AIMS Mechanical dyssynchrony has been postulated to play a pathophysiologic role in heart failure with preserved ejection fraction (HFpEF). METHODS AND RESULTS We quantified left ventricular (LV) systolic dyssynchrony in 130 HFpEF patients with NYHA class II-IV symptoms, ejection fraction (EF) ≥45%, and NT-proBNP levels >400 pg/mL enrolled in the PARAMOUNT trial, and compared them to 40 healt...

OBJECTIVE Follow-up after tetralogy of Fallot (ToF) repair is directed to detect timely right ventricular (RV) dysfunction by following pulmonary regurgitation and global RV size, with little attention for the effective contribution of regional RV dysfunction. This study investigates the contribution of regional RV dysfunction on exercise capacity after ToF repair. METHODS Forty-two patients ...

Aortic valve disease is a fatal disease with but a single cure. Removal of the mechanical obstruction in aortic stenosis (surgery or TAVI) and replacement of an incompetent valve (so far only surgery) are the only treatment options. While aortic valve replacement in patients with isolated valve disease and normal pumpfunction of the heart has become a routine procedure and is performed with exc...

SUMMARY The relationships between the systolic time intervals determined from simultaneous recordings of the electrocardiogram, the phonocardiogram, the carotid arterial pulse tracing, and direct measures of left ventricular performance as assessed angiographically by measurement of left ventricular stroke volume (SV), end-diastolic volume (EDV), and ejection fraction (EF) were studied in 68 pa...

Background Duchenne/Becker muscular dystrophy (D/BMD) is associated with early onset cardiomyopathy, with cardiac fibrosis amongst the earliest manifestations. Changes in conventional estimates of cardiac function (e.g. ejection fraction, EF) may occur late in Duchenne and Becker muscular dystrophy (DMD/BMD). Cardiac MRI tagging is a noninvasive imaging biomarker for quantifying ventricular dys...

The prognostic value of the left ventricular ejection fraction(EF) was compared to that of other commonly used indices--severity of coronary artery disease, left ventricular end-diastolic pressure, cardiac index, and abnormal ECG--in 144 patients with coronary artery disease followed for an average of 14 months on medical management. During this period, 14 patients (10%) died. Analysis of the m...

BACKGROUND Chronic aortic regurgitation (AR) patients demonstrate left ventricular (LV) remodeling with increased LV mass and volume but may have a preserved LV ejection fraction (EF). We hypothesize that in chronic AR, global longitudinal systolic and diastolic function will be reduced despite a preserved LV EF. METHODS We studied with Doppler echocardiography 27 normal subjects, 87 patients...

AIM We assessed the value of cardiovascular magnetic resonance (CMR) criteria ('Lake Louise Criteria') for predicting left ventricular (LV) functional improvement in patients with acute myocarditis. METHODS AND RESULTS We studied 37 patients who referred for acute myocarditis during clinically acute myocarditis and after a 12-month follow-up. CMR sequences sensitive for oedema, hyperaemia, an...

This study aimed to test the ability of real-time three-dimensional echocardiography (RT3DE) to characterize early abnormalities of right ventricular (RV) structure and function with preserved left ventricular (LV) ejection fraction (EF) in uremic patients undergoing peritoneal dialysis (PD). Sixty-six uremic patients with preserved left ventricular ejection fraction (> 50% LVEF) undergoing per...

BACKGROUND Hospitalization for acute heart failure (HF) is associated with high rates of subsequent mortality and readmission. We assessed the influence of the time interval between previous HF hospitalization and randomization in the Candesartan in Heart failure: Reduction in Mortality and morbidity (CHARM) trials on clinical outcomes in patients with both reduced and preserved ejection fracti...
