Background Mitral annular plane systolic excursion (MAPSE) reflects longitudinal left ventricular function, predicts survival in heart failure patients and provides a sensitive marker of early systolic dysfunction in hypertensive patients with normal ejection fraction (EF). Doppler mitral annulus velocity (e’) in early diastole predicts cardiac mortality, differentiates diseases and estimates f...
Interrelationships among left ventricular (LV) size, LV function, and heart size were investigated in 49 patients studied 2-12 months after myocardial infarction. LV end-diastolic volume (EDV) and ejection fraction (EF) were determined by biplane ventriculography. Heart size was estimated from chest films by the cardiothoracic ratio (CTR) and cardiac volume (CV) methods. Ventricular function (i...
Thirty-one left ventricular (LV) biplane angiograms were performed in 28 patients with tricuspid atresia. Measurements of left ventricular end-diastolic volume (LVEDV) and left ventricular end-systolic volume were obtained by the modified Simpson's rule and systolic ejection fraction (EF) calculated. Left ventricular volumes and ejection fractions were also obtained in 19 control patients with ...
salivary gland involvement is one of the radioiodine therapy complications. salivary gland scintigraphy in quantitative mode can accurately evaluate salivary gland function. methods: salivary gland scintigraphy was performed with tc-99m pertechnetate, at the time of iodine therapy as a basic study and then 3 weeks and 3 months afterwards. ejection fraction (ef) of parotid and submandibular glan...
Ejection phase indices such as mean velocity of circumferential fiber shortening (V-cf), ejection fraction (EF), and mean normalized systolic ejection rate (MSER) are thought to reflect the level of left ventricular (LV) inotropic state. Although known to be influenced by changes in afterload, their response to altered preload is less certain. This question was examined in ten normal subjects s...
BACKGROUND Systolic right ventricular (RV) function is an important predictor in the course of various congenital and acquired heart diseases. So far, tricuspid annular motion velocity in systole as obtained by pulsed wave tissue Doppler imaging (TDI) has rarely been investigated for RV function assessment in a sizeable adult patient population. METHODS 258 individuals were included in the st...
INTRODUCTION Cardiac function is influenced by bone marrow transplantation (BMT). Studies have shown the various cardiotoxic effects of high-dose chemotherapy. In this study, we aimed to determine the effects of BMT on cardiac systolic function using echocardiographic indices. MATERIALS AND METHODS Patients with lymphoma (Hodgkin's and non-Hodgkin's), multiple myeloma, and solid tumors which ...
Postextrasystolic potentiation (PESP) and 1-epinephrine infusion have previously been shown by the ventriculographic technique to augment left ventricular wall motion in patients with coronary artery disease. The present study relates the magnitude of this augmentation to short-term prognosis in 56 patients with coronary artery disease and a factor already identified with reduced life expectanc...
AIMS Heart failure (HF) increases the risk of stroke and thrombo-embolism (TE) in non-valvular atrial fibrillation (NVAF), and is incorporated in stroke risk stratification scores. We aimed to establish the role of ejection fraction (EF) in risk prediction in patients with NVAF and HF. METHODS AND RESULTS Patients with NVAF, history of HF, and measured EF were included in a retrospective anal...
