TL;DR: A meta‐analysis of randomized controlled trials of statin loading prior to percutaneous coronary intervention (PCI) found no consistency in the results of these trials between statin and PCI use.
Abstract: Objective
We performed a meta-analysis of randomized controlled trials of statin loading prior to percutaneous coronary intervention (PCI).
Background
Statin loading prior to PCI has been shown to decrease peri-procedural myocardial infarction (pMI) but less is known regarding the clinical benefit of pre-procedural statin loading.
Methods
We searched for trials of statin naive patients presenting with stable angina or NSTE-ACS and treated with statins prior to PCI. We evaluated the incidence of pMI and major cardiac events including spontaneous myocardial infarction, death, and target vessel revascularization.
Results
Out of 1,210 articles, 14 randomized controlled trials were included in this meta-analysis. Among 3,146 patients, 1,591 patients were randomized to a loading dose of statin before PCI and 1,555 patients were given statin therapy initiated only after the PCI. Statin loading prior to PCI was associated with a 56% relative reduction in pMI (OR: 0.44, 95% CI: 0.35–0.56; P < 0.00001). There was a 41% reduction in clinical events in follow-up in the group of patients treated with statin loading prior to PCI (OR: 0.59, 95% CI: 0.38–0.92, P = 0.02). When stratified according to the clinical presentation, the results were only significant for those patients with NSTE-ACS (OR: 0.18, 95% CI: 0.07–0.47; P = 0.0005) and was not noted in the group of patients who underwent PCI for stable angina (OR: 0.92, 95% CI: 0.53–1.61; P = 0.78).
Conclusions
High dose statin therapy given prior to PCI in patients with NSTE-ACS is associated with a reduction in pMI and short-term clinical events. © 2013 Wiley Periodicals, Inc.

TL;DR: The NCDR CAS score, comprising 6 clinical variables, predicts in-hospital S/D after CAS and may be useful to assist clinicians in evaluating optimal management, share more accurate pre-procedural risks with patients, and improve patient selection for CAS.

TL;DR: This paper showed that differences in the type, function and transcriptome of granulocytic-MDSC may explain the severity of COVID-19, in particular the association with pulmonary complications.
Abstract: COVID-19 ranges from asymptomatic in 35% of cases to severe in 20% of patients. Differences in the type and degree of inflammation appear to determine the severity of the disease. Recent reports show an increase in circulating monocytic-myeloid-derived suppressor cells (M-MDSC) in severe COVID 19 that deplete arginine but are not associated with respiratory complications. Our data shows that differences in the type, function and transcriptome of granulocytic-MDSC (G-MDSC) may in part explain the severity COVID-19, in particular the association with pulmonary complications. Large infiltrates by Arginase 1+ G-MDSC (Arg+G-MDSC), expressing NOX-1 and NOX-2 (important for production of reactive oxygen species) were found in the lungs of patients who died from COVID-19 complications. Increased circulating Arg+G-MDSC depleted arginine, which impaired T cell receptor and endothelial cell function. Transcriptomic signatures of G-MDSC from patients with different stages of COVID-19, revealed that asymptomatic patients had increased expression of pathways and genes associated with type I interferon (IFN), while patients with severe COVID-19 had increased expression of genes associated with arginase production, and granulocyte degranulation and function. These results suggest that asymptomatic patients develop a protective type I IFN response, while patients with severe COVID-19 have an increased inflammatory response that depletes arginine, impairs T cell and endothelial cell function, and causes extensive pulmonary damage. Therefore, inhibition of arginase-1 and/or replenishment of arginine may be important in preventing/treating severe COVID-19.

Abstract: We followed 108 patients presenting to the emergency department with atypical chest pain and triaged with stress echocardiography. One-year cardiac event-free survival was 100% with a negative stress echocardiogram and 25% with a positive study.
