... is the most common cause of HF-PSF (heart failure with preserved ejection fraction). Therefore it becomes important to understand the pathophysiological mechanisms underlying diastolic dysfunction, as well as the effective therapeutic strategies able to antagonize its development and progression. Among...

Wu; Cheuk-Man Yu The present study aims to evaluate LV (left ventricular) mechanical dyssynchrony in CAD (coronary artery disease) with preserved and depressed EF (ejection fraction). Echocardiography with TDI (tissue...

... measured oxygen consumption, ventilation, Borg score of perceived exertion and venous lactate concentration, and ejection fractions. 3. As expected, patients had lower peak oxygen consumption [median (range) 1.18 (0.98–1.76) versus 1.935 (1.53–2.31) 1/min; P < 0.001], lower peak venous lactate...

... and 15 hypertensive patients of matched age groups. 2. Average values of cardiac output, ejection fraction, heart rate and left ventricular ejection rate were not significantly different in the two groups. 3. Hypertensive patients had a slower rate of left ventricular filling ( P <0.05), suggesting...

... gated radionuclide cardiac blood pool imaging. 2. We examined 16 ventricular volume curves, using a digital filtering method in the frequency domain to smooth statistical noise. Ejection fraction was unchanged by such filtering but the peak rate of change of volume during systole was greatly affected...

... artery disease as indicated by coronary angiography. 3. There was a close relationship between peak velocity, maximum acceleration and ejection fraction calculated from the left-ventricular angiogram. 4. Three patients with chest pain and no cardiac abnormality detectable by cardiac catheterization had...
