It is well recognized that patients with severe left ventricular (LV) systolic dysfunction develop pulmonary venous hypertension or postcapillary pulmonary hypertension, which leads to an increase in pulmonary vascular resistance (PVR) and right ventricular (RV) systolic failure. It is often underrecognized, however, that patients with heart failure with preserved LV ejection fraction and diast...

Background and Purpose: Sleep breathing disorders have a negative impact on the illness outcome and quality of life in patients with heart failure. This study was conducted to investigate the probability of obstructive sleep apnea in men with heart failure and some related factors. Method: This was a cross-sectional study conducted on 100 male patients with systolic heart failure selected throu...

112 Diastolic heart failure (heart failure with preserved systolic function) causes 30% to 50% of all cases of heart failure, and its prognosis is almost as ominous as that of systolic heart failure. Currently, it is diagnosed when clinical criteria for heart failure are present and left ventricular ejection fraction is preserved (higher than 40% to 50%). However, determinations of brain natriu...

Higher blood pressure and body mass index (BMI) are risk factors for heart failure. It is unknown whether the presence of these risk factors in midadulthood affect the future development of heart failure. In the community-based Framingham Heart Study, we examined the associations of antecedent blood pressure and BMI with heart failure incidence in later life. We studied 3362 participants (57% w...

32 ABSTRACT Central Sleep Apnea (CSA) is one of the most common comorbidities in patients with systolic heart failure. CSA is a manifestation of respiratory control instability that occurs in advanced systolic dysfunction, and can negatively impact the prognosis of heart failure patients. Innovative therapeutic approaches have been introduced and are showing efficacy and positive effect on ca...

BACKGROUND The utility of longitudinal, circumferential, and radial strain and strain rate in determining prognosis in chronic heart failure is not well established. METHODS AND RESULTS In 416 patients with chronic systolic heart failure, we performed speckle-tracking analyses of left ventricular longitudinal, circumferential, and radial strain and strain rate on archived echocardiography ima...

Systolic heart failure is a major problem for Americans today, with 550,000 new cases diagnosed per year, and ultimately contributes to 287,000 deaths annually. While pharmacologic therapy has drastically improved outcomes in patients with systolic heart failure, hospitalizations from systolic heart failure continue to increase and remain a major cost burden. In response to this unmet need, rec...

BACKGROUND Cardiac resynchronization therapy results in improved ejection fraction in patients with heart failure. We sought to determine whether these effects were mediated by changes in contractility, afterload, or volumes. METHODS AND RESULTS In 610 patients with New York Heart Association class I/II heart failure from the Resynchronization Reverses Remodeling in Systolic Left Ventricular ...

background: echocardiographic evaluations of the longitudinal axis of the left ventricular (lv) function have been used in the diagnosis and assessment of heart failure with normal ejection fraction (hfnef). the evaluation of the global and segmental peak systolic longitudinal strains (pslss) by two-dimensional speckle tracking echocardiography (ste) may correlate with conventional echocardiogr...
