Context. Approximately half of patients with overt congestive heart failure (CHF) have diastolic dysfunction without reduced ejection fraction (EF). Yet,
LV performance—Pressure vs. volume curves Fig. 1.2describes the relationship between LV pressure and volume during the cardiac cycle, referred to as the pressure-volume (PV) loop. The early diastolic phase (point A to B) is due to active LV relaxation, and during this time LV suction accou...
postmortem examination.1,4,5Acquired basilar systolic heart murmurs can be associated with endocarditic lesions on either of the semilunar valves, with the aortic valve being most commonly affected.6If sufficiently severe, significant aortic regurgitation can occur, causing a diastolic murmur as well....
We chose to include patients with CHF because the precise underlying pathophysiologic cause of heart failure with preserved ejection fraction is still debated, and abnormalities in these patients include abnormal left ventricular systolic properties; ventricular-arterial coupling; left ventricular diastolic ...
However, the response of diastolic function after an extrasystole is unknown. We studied 58 patients with chronic heart failure (CHF) and two control subjects to evaluate the response of relaxation following extrasystole. At cardiac catheterization, from the derivative of the left ventricular (LV) ...
However, there is still a lack of evidence for the effectiveness of (both non-pharmacological and pharmacological) treatment of patients with "undefined" (e.g. diastolic) heart failure ("elderly female patient in general practice")[52]. In our patient sample, prescription rates of ACE-...
ml/kg/min), greater diameter of the left atrium (49.9 vs. 45.9 mm) and decreased end-diastolic volume (LVEDV = 159.5 vs. 183.7 ml), less frequent occurrence of LBBB (7.5% vs. 13.0%), higher overall mortality (28.3% vs. 17.1%), and more frequent rehospitalizations (15% vs. 8%)....

Thus, in a population-based sample, patients with CHF and normal LV EF were older and overweight, more often women, had renal dysfunction, impaired early diastolic LV relaxation, and concentric LV geometry, whereas patients with CHF and severe LV dysfunction were more often men, had lower body...
Systolic and diastolic asynchrony was calculated using TDI recordings of right ventricular and LV walls. The CHF group consisted of 116 patients. Diastolic asynchrony was more frequent than systolic, concerning both intraventricular (58% vs. 47%; p = 0.0004) and interventricular (72 vs. 45%; p...
