One-year cardiovascular outcomes after coronavirus disease 2019: The cardiovascular COVID-19 registry

Abstract: Background The long-term cardiovascular (CV) outcomes of COVID-19 have not been fully explored. Methods This was an international, multicenter, retrospective cohort study conducted between February and December 2020. Consecutive patients ≥18 years who underwent a real-time reverse transcriptase-polymerase chain reaction (RT-PCR) for SARS-CoV2 were included. Patients were classified into two cohorts depending on the nasopharyngeal swab result and clinical status: confirmed COVID-19 (positive RT-PCR) and control (without suggestive symptoms and negative RT-PCR). Data were obtained from electronic records, and clinical follow-up was performed at 1-year. The primary outcome was CV death at 1-year. Secondary outcomes included arterial thrombotic events (ATE), venous thromboembolism (VTE), and serious cardiac arrhythmias. An independent clinical event committee adjudicated events. A Cox proportional hazards model adjusted for all baseline characteristics was used for comparing outcomes between groups. A prespecified landmark analysis was performed to assess events during the post-acute phase (31–365 days). Results A total of 4,427 patients were included: 3,578 (80.8%) in the COVID-19 and 849 (19.2%) control cohorts. At one year, there were no significant differences in the primary endpoint of CV death between the COVID-19 and control cohorts (1.4% vs. 0.8%; HRadj 1.28 [0.56–2.91]; p = 0.555), but there was a higher risk of all-cause death (17.8% vs. 4.0%; HRadj 2.82 [1.99–4.0]; p = 0.001). COVID-19 cohort had higher rates of ATE (2.5% vs. 0.8%, HRadj 2.26 [1.02–4.99]; p = 0.044), VTE (3.7% vs. 0.4%, HRadj 9.33 [2.93–29.70]; p = 0.001), and serious cardiac arrhythmias (2.5% vs. 0.6%, HRadj 3.37 [1.35–8.46]; p = 0.010). During the post-acute phase, there were no significant differences in CV death (0.6% vs. 0.7%; HRadj 0.67 [0.25–1.80]; p = 0.425), but there was a higher risk of deep vein thrombosis (0.6% vs. 0.0%; p = 0.028). Re-hospitalization rate was lower in the COVID-19 cohort compared to the control cohort (13.9% vs. 20.6%; p = 0.001). Conclusions At 1-year, patients with COVID-19 experienced an increased risk of all-cause death and adverse CV events, including ATE, VTE, and serious cardiac arrhythmias, but not CV death.

Ten-year patterns of stent thrombosis after percutaneous coronary intervention with new- versus early-generation drug-eluting stents: insights from the DECADE cooperation.

Abstract: The DECADE cooperation is a pooled analysis of individual patient data from drug-eluting stent (DES) trials with a 10-year follow-up. This analysis reports the risk of definite stent thrombosis (ST) through to 10 years after percutaneous coronary intervention (PCI) in patients treated with early- and new-generation DES.Individual patient data from 5 DES trials with a 10-year follow-up were pooled. The primary endpoint was definite ST up to 10 years after PCI. Patients were divided into 2 groups as per the generation of DES implanted (early and new DES). Individual participant data were analyzed using a 1-stage approach.We included 9700 patients, 6866 in the new DES group and 2834 in the early DES group. Through to 10 years, definite ST occurred in 69 of 6866 patients treated with new DES and in 91 of 2834 patients treated with early DES (1.0% vs 3.5%, adjusted hazard ratio, 0.32; 95%CI, 0.23-0.45). The rate of definite ST was lower in the new DES group than in the early DES group from 1 to 5 years (rate ratio, 0.14; 95%CI, 0.08-0.26) and from 5 to 10 years (rate ratio, 0.23; 95%CI, 0.08-0.61) after PCI.The incidence of definite ST through to 10 years after PCI with new-generation DES was 1%. New-generation DES are associated with a lower 10-year incidence of definite ST than early-generation DES, particularly beyond 1 year after PCI.

A case-control, multicentre study of consecutive patients with COVID-19 and acute (myo)pericarditis: incidence, risk factors, clinical characteristics and outcomes

Abstract: Objective To estimate incidence, risk factors, clinical characteristics and outcomes of acute (myo)pericarditis (AMP) in patients with COVID-19. Methods Case-control, retrospective review, consecutive case inclusion performed in 62 Spanish EDs. All COVID-19 patients with AMP (cases) were compared in clinical characteristics and outcomes with COVID-19 without AMP (control group A) and non-COVID patients with AMP (control group B). We estimated unadjusted standardised incidence (SI, not adjusted by population’s age/sex) of AMP in COVID-19 and non-COVID populations (per 100 000/year). Results We identified 67 AMP in COVID-19 patients (SI=56.5, OR with respect to non-COVID patients=4.43, 95% CI=3.98 to 4.94). Remarkably, COVID-19 cases presented with chest pain less frequently than non-COVID patients and had less typical ECG changes, higher NT-proBNP (N-terminal prohormone of brain natriuretic peptide), more left and right ventricular dysfunction in echocardiography and more need of inotropic/vasopressor drugs. Admission to intensive care was higher than control group A (OR=3.22, 95% CI=1.43 to 7.23), and in-hospital mortality was higher than control group B (OR=7.75, 95% CI=2.77 to 21.7). Conclusion AMP is unusual as a form of COVID-19 presentation (about 1‰ cases), but SI is more than fourfold higher than non-COVID population, and it is less symptomatic, more severe and has higher in-hospital mortality; therefore, rapid recognition, echocardiographic assessment of myopericardial inflammation/dysfunction and treatment with vasoactive drugs when needed are recommended in AMP in patients with COVID-19.

Coronary Microvascular Angina: A State-of-the-Art Review

Abstract: Up to 60–70% of patients, undergoing invasive coronary angiography due to angina and demonstrable myocardial ischemia with provocative tests, do not have any obstructive coronary disease. Coronary microvascular angina due to a dysfunction of the coronary microcirculation is the underlying cause in almost 50% of these patients, associated with a bad prognosis and poor quality of life. In recent years, progress has been made in the diagnosis and management of this condition. The aim of this review is to provide an insight into current knowledge of this condition, from current diagnostic methods to the latest treatments.

Gender Differences in 10-Year Outcomes Following STEMI: A Subanalysis From the EXAMINATION-EXTEND Trial.

Abstract: Short-term outcomes following ST-segment elevation myocardial infarction (STEMI) in women are worse than in men, with a higher mortality rate. It is unknown whether sex plays a role in very long term outcomes.The aim of this study was to assess whether very long term outcomes following STEMI treatment are influenced by sex.EXAMINATION-EXTEND (10-Year Follow-Up of the EXAMINATION Trial) was an investigator-driven 10-year follow-up of the EXAMINATION (A Clinical Evaluation of Everolimus Eluting Coronary Stents in the Treatment of Patients With ST-Segment Elevation Myocardial Infarction) trial, which randomly 1:1 assigned 1,498 patients with STEMI to receive either everolimus-eluting stents or bare-metal stents. The present study was a subanalysis according to sex. The primary endpoint was the composite patient-oriented endpoint (all-cause death, any myocardial infarction, or any revascularization) at 10 years. Secondary endpoints were individual components of the primary endpoint. All endpoints were adjusted for age.Among 1,498 patients with STEMI, 254 (17%) were women. Overall, women were older, with more arterial hypertension and less smoking history than men. At 10 years, no difference was observed between women and men for the patient-oriented composite endpoint (40.6% vs 34.2%; adjusted HR: 1.14; 95% CI: 0.91-1.42; P = 0.259). There was a trend toward higher all-cause death in women vs men (27.6% vs 19.4%; adjusted HR: 1.30; 95% CI: 0.99-1.71; P = 0.063), with no difference in cardiac death or other endpoints.At very long term follow-up, there were no differences in the combined patient-oriented endpoint between women and men, with a trend toward higher all-cause death in women not driven by cardiac death. The present findings underline the need for focused personalized medicine in women after percutaneous revascularization aimed at both cardiovascular and sex-specific risk factor control and targeted treatment.

Magnesium-based resorbable scaffold vs permanent metallic sirolimus-eluting stent in patients with ST-segment elevation myocardial infarction: 3-year results of the MAGSTEMI randomised controlled trial.

Abstract: BACKGROUND Long-term safety and performance of magnesium-based bioresorbable scaffolds (MgBRS) in ST-segment-elevation myocardial infarction (STEMI) patients are uncertain. AIMS To report the 3-year clinical outcomes of the MAGSTEMI trial. METHODS This investigator-driven, multicentre, randomised, single-blind, controlled trial randomised STEMI patients 1:1 to MgBRS or to permanent metallic sirolimus-eluting stents (SES) at 11 academic centres. The main secondary endpoints included device-oriented composite endpoints (DoCE) and patient-oriented composite endpoints (PoCE), their individual components, any bleeding, and device thrombosis rate. All endpoints were defined according to the Academic Research Consortium. Events were adjudicated by an independent committee. RESULTS Three-year clinical follow-up was obtained in 142 (90.0%) patients. At 3-year follow-up, MgBRS were associated with a higher rate of DoCE than SES (13 [17.6%] vs 5 [6.6%], diff -11.0 [95% CI: -21.3 to -0.7]; p=0.038). This difference was driven by an increased incidence of DoCE within the first year of follow-up. In the landmark analysis, there was no difference between 1 and 3 years (0 [0.0%] vs 1 [1.4%]; p=1.000). The difference in the rate of DoCE was driven by a higher incidence of target lesion revascularisation (TLR) in the MgBRS group compared to SES (12 [16.2%] vs 4 [5.3%]; diff -10.9% [95% CI: -20.7 to -1.2]; p=0.030). The difference in TLR was observed during the first year, with no further differences observed between 1 and 3 years (0 [0.0%] vs 1 [1.4%]; p=1.000). CONCLUSIONS At 3-year follow-up, MgBRS were associated with a higher rate of TLR, which was clustered within the first year, compared to SES.

Direct actions of dapagliflozin and interactions with LCZ696 and spironolactone on cardiac fibroblasts of patients with heart failure and reduced ejection fraction

Abstract: Inhibitors of SGLT2 (SGLT2i) have shown a positive impact in patients with chronic heart failure and reduced ejection fraction (HFrEF). Nonetheless, the direct effects of SGLT2i on cardiac cells and how their association with main drugs used for HFrEF affect the behaviour and signalling pathways of myocardial fibroblasts are still unknown. We aimed to determine the effects of dapagliflozin alone and in combination with sacubitril/valsartan (LCZ696) or spironolactone on the function of myocardial fibroblasts of patients with heart failure and reduced ejection fraction (HFrEF).

An open secret in porcine acute myocardial infarction models: The relevance of anaesthetic regime and breed in ischaemic outcomes

Abstract: Large animal models of acute myocardial infarction (AMI) play a crucial role in translating novel therapeutic approaches to patients as denoted by their use in the right-before-human testing platform. At present, the porcine model of AMI is used most frequently as it mimics the human condition and its anatomopathological features accurately. We want to describe to, and share with, the translational research community our experience of how different anaesthetic protocols (sevoflurane, midazolam, ketamine+xylazine+midazolam, and propofol) and pig breeds [Large White and Landrace x Large White (LLW)] can dramatically modify the outcomes of a well-established porcine model of closed-chest AMI. Our group has extensive experience with the porcine model of reperfused AMI and, over time, we reduced the time of ischaemia used to induce the disease from 90 to 50 min to increase the salvageable myocardium for cardioprotection studies. For logistical reasons, we changed both the anaesthetic protocol and the pig breed used, but these resulted in a dramatic reduction in the size of the myocardial infarct, to almost zero in some cases (sevoflurane, 50-min ischaemia, LLW, 2.4 ± 3.9% infarct size), and the cardiac function was preserved. Therefore, we had to re-validate the model by returning to 90 min of ischaemia. Here, we report the differences in infarct size and cardiac function, measured by different modalities, for each combination of anaesthetic protocol and pig breed we have used. Furthermore, we discuss these combinations and the limited literature pertaining to how these two factors influence cardiac function and infarct size in the porcine model of AMI.

Circulating miRNA Fingerprint and Endothelial Function in Myocardial Infarction: Comparison at Acute Event and One-Year Follow-Up

Abstract: MicroRNAs (miRNA) are major regulators of intercellular communication and key players in the pathophysiology of cardiovascular disease. This study aimed to determine the miRNA fingerprint in a cohort of 53 patients with acute myocardial infarction (AMI) with non-ST-segment elevation (NSTEMI) relative to miRNA expression in healthy controls (n = 51). miRNA expression was initially profiled by miRNA array in the serum of patients undergoing cardiac catheterization during NSTEMI (n = 8) and 1 year past the event (follow-up, n = 8) and validated in the entire cohort. In total, 58 miRNAs were differentially expressed during AMI (p < 0.05), while 36 were modified at follow-up (Fisher’s exact test: p = 0.0138). Enrichment analyses revealed differential regulation of biological processes by miRNA at each specific time point (AMI vs. follow-up). During AMI, the miRNA profile was associated mainly with processes involved in vascular development. However, 1 year after AMI, changes in miRNA expression were partially related to the regulation of cardiac tissue morphogenesis. Linear correlation analysis of miRNA with serum levels of cytokines and chemokines revealed that let-7g-5p, let-7e-5p, and miR-26a-5p expression was inversely associated with serum levels of pro-inflammatory cytokines TNF-α, and the chemokines MCP-3 and MDC. Transient transfection of human endothelial cells (HUVEC) with let-7e-5p inhibitor or mimic demonstrated a key role for this miRNA in endothelial function regulation in terms of cell adhesion and angiogenesis capacity. HUVEC transfected with let-7e-5p mimic showed a 20% increase in adhesion capacity, whereas transfection with let-7e-5p inhibitor increased the number of tube-like structures. This study pinpoints circulating miRNA expression fingerprint in NSTEMI patients, specific to the acute event and changes at 1-year follow-up. Additionally, given its involvement in modulating endothelial cell function and vascularization, altered let-7e-5p expression may constitute a therapeutic biomarker and target for ischemic heart disease.

Multivessel spontaneous coronary artery dissection: Clinical features, angiographic findings, management, and outcomes.

Abstract: BACKGROUND Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome. Multivessel (MV) SCAD is a challenging clinical presentation that might be associated to a worse prognosis compared with patients with single-vessel (SV) involvement. METHODS The Spanish multicentre nationwide prospective SCAD registry included 389 consecutive patients. Patients were classified, according to the number of affected vessels, in SV or MV SCAD. Major adverse events (MAE) were analyzed during hospital stay and major cardiac or cerebrovascular adverse events (MACCE) at long-term clinical follow-up. RESULTS A total of 41 patients (10.5%) presented MV SCAD. These patients had more frequently a previous history of hypothyroidism (22% vs 11%, p = 0.04) and anxiety disorder (32% vs 16%, p = 0.01). MV SCAD patients presented more often as non-ST segment elevation myocardial infarction (73% vs 52%, p = 0.01) and showed less frequently type 1 angiographic lesions (12% vs 21%, p = 0.04). An impaired initial Thrombolysis In Myocardial Infarction (TIMI) flow 0-1 was less frequent (14% vs 29%, p < 0.01) in MV SCAD. In both groups, most patients were treated conservatively (71% vs 79%, p = NS). No differences were found regarding in-hospital MAE or MACCE at late follow-up (median 29 ± 11 months). However, the rate of stroke was higher in MV SCAD patients, both in-hospital (2.4% vs 0%, p < 0.01) and at follow-up (5.1% vs 0.6%, p = 0.01). CONCLUSIONS Patients with MV SCAD have some distinctive clinical and angiographic features. Although composite clinical outcomes, in-hospital and at long-term follow-up, were similar to those seen in patients with SV SCAD, stroke rate was significantly higher in patients with MV SCAD.

Immediate versus staged revascularisation of non-culprit arteries in patients with acute coronary syndrome: a systematic review and meta-analysis

Abstract: Although there is robust evidence that revascularisation of non-culprit vessels should be pursued in patients presenting with an acute coronary syndrome (ACS) and multivessel coronary artery disease (MVD), the optimal timing of complete revascularisation remains disputed. In this systematic review and meta-analysis our results suggest that outcomes are comparable for immediate and staged complete revascularisation in patients with ACS and MVD. However, evidence from randomised controlled trials remains scarce and cautious interpretation of these results is recommended. More non-biased evidence is necessary to aid future decision making on the optimal timing of complete revascularisation.

Impact of Age at the Time of the First ST-Elevation Myocardial Infarction on 10-Year Outcomes (from the EXAMINATION-EXTEND Trial).

Abstract: The aim of this substudy of the EXAMINATION-EXTEND was to analyze 10-year outcomes according to the patient's age at the time of the first ST-elevation myocardial infarction (STEMI). Of 1,498 patients with STEMI included in the EXAMINATION-EXTEND study, those with a previous history of coronary ischemic even or ischemic stroke were excluded from this analysis. The remaining 1,375 patients were divided into 4 age groups: <55, 55 to 65, 65 to 75, and >75 years. The primary end point was 10-year patient-oriented composite end point (POCE) of all-cause death, any MI, or any revascularization. At 10-year follow-up, patients aged <55 years (adjusted hazard ratio [HR] 0.24, 95% confidence interval [CI] 0.18 to 0.31, p = 0.001), 55 to 65 years (adjusted HR 0.26, 95% CI 0.20 to 0.34, p = 0.001), and 65 to 75 years (adjusted HR 0.38, 95% CI 0.30 to 0.50, p = 0.001) showed lower risk of POCE than those aged >75 years, led by a lower incidence of all-cause death (<55 : 6% vs 55 to 65: 11.9% vs 65 to 75: 25.7% vs >75 years: 61.6%, p = 0.001). Cardiac death was more prevalent in the older group (<55: 3.7% vs 55 to 65: 5.8% vs 65 to 75: 10.9% vs >75 years: 35.5%, p = 0.001). In the landmark analyses, between 5- and 10-year follow-up, young patients exhibited a higher incidence of any revascularization (<55: 7.4% vs 55 to 65: 4.9% vs 65 to 75: 1.8% vs >65 years: 1.6%, p = 0.001). In conclusion, in patients with a first STEMI, advanced age was associated with high rates of POCE at 10-year follow-up due to all-cause and cardiac death. Conversely, younger patients exhibited a high risk of revascularization at long-term follow-up.

Changes in the treatment strategy following intracoronary pressure wire in a contemporaneous real-life cohort of patients with intermediate coronary stenosis. Results from a nationwide registry.

Abstract: BACKGROUND Intracoronary pressure wire is useful to guide revascularization in patients with coronary artery disease. AIMS To evaluate changes in diagnosis (coronary artery disease extent), treatment strategy and clinical results after intracoronary pressure wire study in real-life patients with intermediate coronary artery stenosis. METHODS Observational, prospective and multicenter registry of patients in whom pressure wire was performed. The extent of coronary artery disease and the treatment strategy based on clinical and angiographic criteria were recorded before and after intracoronary pressure wire guidance. 12-month incidence of MACE (cardiovascular death, non-fatal myocardial infarction or new revascularization of the target lesion) was assessed. RESULTS 1414 patients with 1781 lesions were included. Complications related to the procedure were reported in 42 patients (3.0 %). The extent of coronary artery disease changed in 771 patients (54.5 %). There was a change in treatment strategy in 779 patients (55.1 %) (18.0 % if medical treatment; 68.8 % if PCI; 58.9 % if surgery (p < 0.001 for PCI vs medical treatment; p = 0.041 for PCI vs CABG; p < 0.001 for medical treatment vs CABG)). In patients with PCI as the initial strategy, the change in strategy was associated with a lower rate of MACE (4.6 % vs 8.2 %, p = 0.034). CONCLUSIONS The use of intracoronary pressure wire was safe and led to the reclassification of the extent of coronary disease and change in the treatment strategy in more than half of the cases, especially in patients with PCI as initial treatment.

Safety and feasibility of transradial access for percutaneous coronary intervention in chronic total occlusions.

Abstract: Transfemoral access is the most frequently used vascular approach in chronic total occlusion percutaneous coronary interventions (CTO-PCI). The aim of this study was to evaluate the safety and feasibility of a transradial access CTO-PCI program and its impact on angiographic and clinical results and length of hospital stay. Retrospective multicenter cohort study including 2550 consecutive CTO-PCI procedures included in a multicenter registry with accurate information on vascular access. A total of 896 procedures were performed as radial-only access while 1654 were performed through at least 1 femoral puncture. Clinical and angiographic data were collected. The mean age was 66.3 ± 11.4 years. The mean Japan-chronic total occlusion score (2.7 ± 0.3) was similar in the 2 groups. Successful revascularization was achieved in 2009 (79.6%) cases, 78.2% and 82.1% in the femoral and radial access cohorts, respectively (P = .002). Periprocedural in-hospital complications were observed in 5.1% and 2.3% (P = .02), with fewer access site-dependant vascular complications in the transradial cohort (2.3% vs 0.2%; P = .009). The mean length of hospital stay was significantly shorter in the transradial access group (0.89 ± 1.4 vs 2.2 ± 3.2 days, P < .001). A transradial program for CTO-PCI is safe and effective in most CTO lesions. The transradial strategy has fewer vascular complications and shorter length of hospital stay without compromising the success rate. El acceso femoral es la vía vascular mayoritariamente utilizada en intervenciones coronarias percutáneas de desobstrucción de oclusiones totales crónicas (ICP-OTC). El objetivo de este estudio fue evaluar la viabilidad y seguridad del acceso radial en un programa de ICP-OTC y su impacto sobre el resultado clínico y angiográfico y la duración de la estancia hospitalaria. Estudio multicéntrico retrospectivo de cohortes en el que se incluyeron de forma consecutiva 2.550 procedimientos de ICP-OTC con información precisa sobre acceso vascular. Un total de 896 casos se realizaron por acceso radial puro y 1.654 se realizaron con al menos una punción femoral. Se analizaron datos clínicos y angiográficos. La edad media fue de 66,3 ± 11,4 años. La puntuación Japan-chronic total occlusion (J-CTO) fue similar en ambos grupos (2,7 ± 0,3). El éxito del procedimiento se obtuvo en un 79,6% de los procedimientos, 78,2% y 82,1% en la cohorte transfemoral y transradial respectivamente p = 0,02). Las complicaciones intrahospitalarias periprocedimiento se observaron en el 5,1% y el 2,3% (p = 0,02), con un menor número de complicaciones vasculares dependientes del sitio de punción (2,3% frente a 0,2%, p = 0,009). La duración media del ingreso hospitalario fue significativamente menor en el grupo radial (0,89 ± 1,4 frente a 2,2 ± 3,2 días; p < 0,001). Un programa de acceso radial para la ICP-OTC es seguro y efectivo para la mayoría de las oclusiones. La estrategia transradial permite un menor número de complicaciones vasculares y una estancia media más corta sin comprometer la tasa de éxito del procedimiento.

Overlapping versus single long stents in long chronic total occlusions: insights of the Iberian CTO Registry.

Abstract: BACKGROUND It is unknown whether the availability of long drug-eluting stents modify the PCI strategy of long CTO. To describe the contemporary PCI strategy of long chronic total occlusions (CTO) using overlapping (OS) or single long stents (SS) and to analyze its results. METHODS 2842 consecutive CTO PCIs were included. T hose with an occlusion length ≥20 mm in which ≥ 1 DES was implanted were analyzed. We compared procedural characteristics and clinical outcomes of CTO treated with OS or SS. RESULTS 1088 CTO PCIs were analyzed (79.9% males; 64.7±10.6 years). Mean J-score was 2.8 ± 0.9. A SS was used in 38.5% of cases and OS in 61.5%. Total stent length was 64.1±29.9 mm; it was higher in the OS group (OS:79.9±25.5 mm vs SS:38.3±14.7 mm; p<0.0001). Mean number of stents in the OS group was 2.3±1. Very long stents (≥40 mm) were used in 27.4% of cases, more frequently in the OS group (OS:32.4% vs SS:19.3%; p<0.0001). After a mean follow-up of 19±15.9 months, the rate of adverse events (MACE) was 2% (cardiac death:1.6%, myocardial infarction:1.6%, target lesion revascularization:1.9% and stent thrombosis: 0.18%) with no significant differences between both groups. Overlapping was not an independent predictor of MACE. CONCLUSIONS In long CTO PCIs, OS is more frequently used than single stenting, especially in more complex procedures. Clinical outcomes at a mid-term follow-up are favorable. Using newer generation DES, overlapping was not an independent predictor of MACE, however a trend toward a higher event rate was observed in the OS group.

Long-term effects of coronavirus disease 2019 on the cardiovascular system: the CV COVID-19 registry

Abstract: Abstract Background Patients with COVID-19 have an increased risk of cardiovascular adverse events during the acute phase. However, the long-term cardiovascular outcomes are unknown. Objective We aimed to determine the long-term effects of COVID-19 in the cardiovascular system. Methods This is a multicenter, observational, retrospective registry conducted at 17 centers in Spain and Italy. Consecutive patients older than 18 years who underwent a real-time reverse transcriptase-polymerase chain reaction (RT-PCR) for SARS-CoV2 in the participating institutions were included. Patients were classified into two groups, according to the results of the RT-PCR: COVID-19 positive or negative. The primary outcome was cardiovascular (CV) death at 1-year. The secondary outcomes included acute myocardial infarction, stroke, heart failure hospitalization, pulmonary embolism, and serious cardiac arrhythmias at 1-year. Outcomes were compared between the two groups. An independent clinical event committee adjudicated events. Results A total of 4427 patients were included, 3578 (80.8%) patients with COVID-19 and 849 (19.2%) without COVID-19. COVID-19 patients were older, had a higher rate of classical cardiovascular risk factors, except for active smoking, and had fewer comorbidities. At a median time of 13.5 (IQR 11.8–15.8) months, after an adjustment by baseline characteristics, there was no difference in CV death (1.4% vs. 1.1%; HR 1.03 [0.49–2.18]; p=0.941) between patients with COVID-19 and without. However, COVID-19 patients experienced higher rate of venous thromboembolism (VTE) (3.9% vs. 0.6%, HR 6.11 [2.46–15.16]; p=0.001), major bleeding (2.9% vs. 0.5%, HR 5.38 [1.95–14.84]; p=0.001), and serious cardiac arrhythmias (2.6% vs. 0.9%, HR 2.25 [1.07–4.73]; p=0.033). During follow-up, between discharge and end of follow-up, COVID-19 patients did not experience a higher risk of adverse cardiovascular outcomes (composite of CV death, any MI, ischemic stroke, systemic arterial thrombosis, VTE, heart failure hospitalization, or any serious arrhythmia) compared to patients without (HR 0.80; [0.53–1.21]; p=0.298). Conclusions At 1-year follow-up, COVID-19 was not associated with an increased risk of cardiovascular death but with a higher risk of VTE events, major bleeding, and serious cardiac arrhythmias. COVID-19 was not associated with a higher risk of adverse cardiovascular events during follow-up. Funding Acknowledgement Type of funding sources: Public grant(s) – National budget only.

29 prognostic impact of target vessel failure as first event after st-segment elevation myocardial infarction: insight form 10-year follow-up of the examination extend trial

Abstract: Outcome after primary PCI for ST-segment elevation myocardial infarction may be very different. Either it may be free of events during years or it may be characterized by many recurrent events. It is unknown whether to have a target vessel failure (TVF) as first event may impact subsequent outcomes during follow-up. We aim to evaluate very long-term outcomes of STEMI patients according to the occurrence of TVF as the first event during follow-up. EXAMINATION-EXTEND trial randomized STEMI patients to everolimus-eluting stent or bare-metal stent with 10-year follow-up. All the patients were stratified according to their first event (TVF-First vs. NonTVF-First). TVF was defined as the composite of TV cardiac death, TV myocardial infarction, or TV revascularization. The primary endpoint of this study was 10-year POCE, defined as the composite of all-cause death, any myocardial infarction, or any revascularization. Out of the 1498 enrolled patients, 161 (10.7%) had a TVF as first clinical event during follow-up. TVF-First patients had higher rates of previous MI or PCI, with less use of manual thrombectomy, and received more BMS with a longer total stent length. On multivariate analysis, manual thrombectomy and bare-metal stent implantation were independent predictors of TVF as first event. Ten-year adjusted POCE was statistically higher in TVF-First patients compared to the NonTVF-First group (31.1% vs 27.5%, adjHR: 1.82; 95%CI: 1.34 - 2.48; p < 0.001). In our STEMI population TVF occurred in 10.7% as the first event during follow-up. At 10-year follow-up, patients who experienced a TVF as first event exhibited a high risk for subsequent POCE events as compared to patients who did not.

Atrial fibrillation and acute coronary syndromes in nonagenarians

Abstract: Type of funding sources: None. Atrial fibrillation (AF) is the most common arrhythmia in the elderly. Age increases both thromboembolic risk and bleeding complications. However, these patients are not anticoagulated on many occasions. AF in the context of acute coronary syndrome (ACS) increases the complexity of the management of these patients and they are underrepresented in clinical trials. The objective of the study was to analyze the impact of AF in nonagenarian patients at 12 months. Other objectives were to evaluate the therapeutic strategy for ACS and AF and to compare clinical events according to AF subtype and treatment at discharge. A retrospective, multicenter and observational study was carried out, in which all nonagenarian patients admitted for ACS and AF (prevalent or incident) between 2005 and 2018 were consecutively included. Patients with type 2 myocardial infarction were excluded. Baseline characteristics were analyzed and mortality at 12 months was analyzed in all patients and according to AF subtype (incident AF was considered when occurred during admission and prevalent AF was considered in patients with previous history of AF) 680 patients with a mean age of 92.6 ± 2.4 years were analyzed. Patients with AF more frequently presented chronic kidney disease (CKD) and non-ST-segment elevation acute coronary syndrome (Non-STEMI) and arterial hypertension (HBP) (Table 1). Mortality rate was similar in patients with previous AF and those without history of AF (Figure 1 A). 21.6% (147) of the patients had AF at admission, of which only 47.7% of the patients were previously anticoagulated. Treatment at discharge is shown in Figure 1 B. Mortality at 1 year according to discharge treatment and AF subtype are represented in figures 1C and 1D. This is the largest registry of ACS and AF in this population. Patients with prevalent AF had more frequent Non-STEMI and comorbidities, with a similar mortality to AF subgroup at 1 year. Previous AF was no related to higher mortality in this cohort. Half of the patients were not anticoagulated at discharge. OAC was not associated with prognostic benefit in our series.

Data standards for transcatheter aortic valve implantation: the European Unified Registries for Heart Care Evaluation and Randomised Trials (EuroHeart).

Abstract: AIMS Standardized data definitions are necessary for the quantification of quality of care and patient outcomes in observational studies and randomised controlled trials (RCTs). The European Unified Registries for Heart Care Evaluation and Randomised Trials (EuroHeart) project of the European Society of Cardiology (ESC) aims to create pan-European data standards for cardiovascular diseases and interventions, including transcatheter aortic valve implantation (TAVI). METHODS AND RESULTS We followed the EuroHeart methodology for cardiovascular data standard development. A Working Group of 29 members representing 12 countries was established and included a patient representative, as well as experts in the management of valvular heart disease from the European Association of Percutaneous Cardiovascular Interventions (EAPCI), the European Association of Cardiovascular Imaging (EACVI) and the Working Group on Cardiovascular Surgery. We conducted a systematic review of the literature and used a modified Delphi method to reach consensus on a final set of variables. For each variable, the Working Group provided a definition, permissible values and categorized the variable as mandatory (Level 1) or additional (Level 2) based on its clinical importance and feasibility. In total, 93 Level 1 and 113 Level 2 variables were selected, with the level 1 variables providing the dataset for registration of patients undergoing TAVI on the EuroHeart IT platform. CONCLUSION This document provides details of the EuroHeart data standards for TAVI processes of care and in-hospital outcomes. In the context of EuroHeart, this will facilitate quality improvement, observational research, registry-based RCTs and post-marketing surveillance of devices and pharmacotherapies.
