Impact of left ventricular mass/end-diastolic volume ratio by three-dimensional echocardiography on two-dimensional global longitudinal strain and diastolic function in native hypertensive patients.

Abstract: BACKGROUND In hypertensive patients, high left ventricular (LV) mass/end-diastolic volume ratio (LVM/EDV) is related to LV dysfunction and myocardial fibrosis. PURPOSE We examined the ability of 3D-echo-derived LVM/EDV ratio in identifying early systolic and diastolic dysfunction in relation with LV concentric geometry in native hypertensive patients. METHODS One-hundred and forty-four newly diagnosed, never treated hypertensive patients underwent 2D-echo, including computation of 2D-derived global longitudinal strain (GLS), and 3D-echo. The study population was divided into two groups: elevated 3D-LVM/EDV (≥1.23 in women and ≥1.22 in men), corresponding to LV concentric geometry (n = 50), and normal ratio (<1.23 in women and <1.22 in men) corresponding to LV normal or eccentric geometry (n = 94). RESULTS The two groups were comparable for sex, heart rate, BMI, and blood pressure (BP). Patients with elevated 3D-LVM/EDV ratio were older and had lower GLS (P < 0.001) than patients with normal LVM/EDV ratio. Transmitral E/A ratio (P < 0.0001) and e' velocity (P < 0.0001) were lower, and E/e' ratio (P < 0.0001) higher in patients with elevated LVM/EDV ratio. In the pooled population, LVM/EDV ratio was positively correlated to E/e' (r = 0.39, P < 0.0001) and negatively to GLS (r = -0.29, P < 0.001). By separate multilinear regression analyses, after adjusting for sex, age, heart rate, mean BP and BMI, LVM/EDV ratio - but not 2D-relative wall thickness - was independently associated with E/e' (β = 0.304, P = 0.003) and GLS (β = -0.501, P < 0.0001). CONCLUSION Three-dimensional echocardiographic assessment of LV concentric geometry allows identifying an early diastolic and longitudinal systolic dysfunction in native hypertensive patients. In particular, 3D-LVM/EDV ratio is independently associated with both E/e' ratio and GLS.

Relationship between pulse pressure variation and echocardiographic indices of left ventricular filling pressure in critically ill patients.

Abstract: Summary Background Pulse pressure variation (PPV) is a dynamic index of fluid responsiveness. This parameter helps clinicians in improving haemodynamic status while avoiding potential fluid overload. Echocardiographic indices, such as E/E' ratio and left atrial (LA) strain by speckle tracking echocardiography (STE), are used to estimate left ventricular (LV) filling pressures. This study aimed at exploring the relationship between PPV and echocardiographic indices of LV filling pressures in critically ill patients. Methods Twenty-two patients (mean age of 50·9 ± 21·6, male/female = 15/7) admitted to intensive care unit, and requiring mechanical ventilation and invasive arterial pressure monitoring, were studied. In all patients, two independent operators assessed simultaneously PPV, using a pulse contour method, mean E/E' ratio and peak atrial longitudinal strain (PALS) by means of STE. PALS values were obtained by averaging LA segments measured in the 4-chamber and 2-chamber views (global PALS). Results A significant negative correlation was found between mean E/E' ratio and PPV (R2 = −0·76; P 15%. Conclusion In a group of mechanically ventilated patients PPV, derived from pulse contour analysis, and echocardiographic preload parameters were well correlated. Global PALS by STE provided better estimation of PPV than mean E/E' ratio. PALS seems a potential alternative to PPV in assessing fluid responsiveness in critically ill patients.

Favourable interaction of calcium antagonist plus ACE inhibitor on cardiac haemodynamics in treating hypertension: rest and effort evaluation.

Abstract: The aim of the study was to evaluate the effects of verapamil sustained release (SR) 240 mg, enalapril and their combination on blood pressure (BP) and cardiac haemodynamics at rest and during exercise in 20 patients with moderate essential hypertension (seven men and 19 women, mean age±s.d. 59.7±15.8 years). After a 4 week placebo run-in period, patients were randomly allocated to received verapamil SR 240 mg once daily or enalapril 20 mg once daily for 4 weeks in a double-blind fashion. Patients whose diastolic blood pressure (DBP) was still ≥95 mm Hg at the end of this period received verapamil SR plus enalapril for an additional 4 weeks. At the end of the placebo, single and combined treatment periods, resting and exercise (bicycle ergometry) haemodynamics were evaluated by radionuclide ventricular angiography (technetium-99m) and the following parameters were assessed: BP, heart rate, double product, systemic vascular resistances (SVR), cardiac output (CO), stroke volume (SV), ejection fraction (EF) mean ejection rate (mER) and peak filling rate (PFR). Both verapamil SR and enalapril monotherapies significantly reduced resting and exercise BP (P<0.01), with a BP normalisation (DBP≤95 mm Hg) of five of 10 and 4 of 10 patients respectively. A greater BP fall and a normalisation of 11 of 11 patients was obtained in non-responders to monotherapy, when treated with verapamil SR and enalapril (P<0.01). Verapamil SR also reduced heart rate at rest and during exercise (-11.8% and -18.4%, respectively, P<0.05). Double product was significantly reduced at rest and during exercise in the verapamil group (P<0.01); enalapril alone and verapamil plus enalapril reduced double product only at rest (P<0.01). Resting and exercise SVR significantly decreased in the verapamil, enalapril and combined treatment groups (rest -16%, -19% and -15%; exercise -19%, -18% and -15%, respectively, P<0.01). Left ventricular function showed a trend towards improvement after monotherapies; CO, EF and mER significantly improved with the combined regimen. In conclusion, verapamil SR and enalapril in a once a day administration were effective in the treatment of moderate hypertension, their anti-hypertensive effect was associated with a significant reduction of SVR. A further BP reduction was obtained with the combination of the two drugs that induced a reduction of SVR with a good tolerability profile. The better BP reduction obtained with the combination of the two drugs was associated with an improvement of left ventricular function particularly during effort where, for any reduction in DBP, there was more improvement in SV and CO

Can echocardiography improve the prediction of thromboembolic risk in atrial fibrillation? Evidences and perspectives

Abstract: Atrial fibrillation is the most common arrhythmia and its prevalence is expected to further increase. Patients with atrial fibrillation have an increased risk of stroke (fivefold increased risk), heart failure, and death. In patients with non-valvular atrial fibrillation, the most recent guidelines recommend the use of the CHA2DS2-VASc (congestive heart failure, arterial hypertension, age > 75 years, diabetes mellitus, stroke/transient ischemic attack, vascular disease, age 65–74 years, sex category) scoring system to identify those who may benefit from oral anticoagulant treatment. Guidelines recommend initiation of oral anticoagulation with vitamin K antagonists or direct oral anticoagulants in men with a score ≥ 2 and in women with a score ≥ 3, while oral anticoagulation in individuals with a score of 0 is not recommended. Accordingly, men with CHA2DS2VASc score = 1 (and women with CHA2DS2VASc = 2) represent a grey zone where guidelines do not provide a definite oral anticoagulant indication. Implementation of risk stratification with transthoracic echocardiography could be extremely useful. Both prospective and observational studies using transthoracic echocardiography prediction of events and studies utilizing transesophageal echocardiographic parameters as surrogate markers of thromboembolic events make sustainable the hypothesis that echocardiography could improve thromboembolism prediction in non-valvular atrial fibrillation. However, because of some controversial results of different studies, determination of the best echocardiographic parameter predicting thromboembolic events in atrial fibrillation remains uncertain. The combination of left atrial enlargement with left atrial function (in particular assessing left atrial strain) appears to be very valuable, but needs to be confirmed in large-scale multi-center trials.

Recommendations for cardiac chamber quantification by echocardiography in adults: an update from the American Society of Echocardiography and the European Association of Cardiovascular Imaging.

Abstract: The rapid technological developments of the past decade and the changes in echocardiographic practice brought about by these developments have resulted in the need for updated recommendations to the previously published guidelines for cardiac chamber quantification, which was the goal of the joint writing group assembled by the American Society of Echocardiography and the European Association of Cardiovascular Imaging. This document provides updated normal values for all four cardiac chambers, including three-dimensional echocardiography and myocardial deformation, when possible, on the basis of considerably larger numbers of normal subjects, compiled from multiple databases. In addition, this document attempts to eliminate several minor discrepancies that existed between previously published guidelines.
