introduction: coronary artery bypass graft can improve myocardial contractility and functional class in ischemic heart disease. materials & methods: this study was done on 200 patient’s with cabg operation during 6 months. 142 patients were men and 56 patients were women with mean age 57.7  9.2 years (36-83). ef was measured by echocardiography before & 1 week after cabg, ccsfc evaluated befor...

coronary artery disease is one of the most common causes of mortality and morbidity across the world. its treatment includes medical treatment, coronary artery bypass graft (cabg) and percutaneous coronary intervention (pci). the purpose of this study was to investigate the effect of pci on echocardiographic findings of left ventricular (lv) systolic and diastolic function. 115 patients with co...

Background: Study the correlation between the left ventricular end diastolic volume (LVEDV), ejection fraction (EF) and the development of arrhythmia. Patients and methods: Two hundreds patients with documented acute coronary syndrome and myocardial infection with dysrhythmia documented by ECG and holter monitoring assessed at the cardiac department at Baghdad teaching hospital over the period ...

Current guidelines for the management of heart failure (HF) divide patients with HF into 2 categories: those with reduced ejection fraction (EF of ≤40%; HFrEF) and those with preserved ejection fraction (>40%; HFpEF). It has been recognized that a subset of patients with HFpEF previously had HFrEF. These patients with recovery or improvement in EF (HFiEF) may be clinically distinct from those w...

BACKGROUND Heart failure with recovered or improved ejection fraction (HFiEF) has been proposed as a new category of HF. Whether HFiEF is clinically distinct from HF with persistently reduced ejection fraction remains to be validated. METHODS AND RESULTS Of the 5010 subjects enrolled in the Valsartan Heart Failure Trial (Val-HeFT), 3519 had a baseline left ventricular EF of <35% and a follow-...

30 patients with delayed contrast enhancement in patterns suggestive of myocardial infarctions were reviewed. Infarct mass was quantitatively measured using short axis images obtained in the delayed phase of gadopentetate administration. Left ventricular mass and ejection fraction were measured using short axis, steady state free precession images. A relationship is drawn between increased mass...

During these more than 20 years of evolution in understandings the mechanisms heart failure (HF) with preserved fractional ejection, there has been a rich variety terminology, including „diastolic failure“, „heart systolic function“ and fraction“. By defi nition, latter term “ejection fraction-induced failure” proved to be most appropriate was accepted as correct, presence diastolic dysfunction ...

Previous reports have suggested that left ventricular first-third ejection fraction (EF) can be obtained from the left ventricular time-activity curve derived from first-pass radionuclide angiography based on Anger camera data. The validity of this technique was assessed by: a study of beat-to-beat variations in data from 15 patients in which electrocardiographic data were simultaneously record...

Left ventricular ejection fraction (LVEF) remains the most commonly utilized metric of cardiac function and has been related to outcomes in patients across the spectrum of heart failure (HF). In patients with HF and reduced ejection fraction (EF), LVEF had been shown to be predictive of cardiovascular death, HF hospitalization, and all-cause mortality in a relatively linear fashion, with those ...

OBJECTIVE To investigate the value of Simpson's rule, Teichholz's formula, and recording of mitral ring motion in assessing left ventricular ejection fraction (EF) in patients with left ventricular hypertrophy. DESIGN Left ventricular ejection fraction calculated by Simpson's rule and by Techholz's formula and estimated by mitral ring motion was compared with values obtained by radionuclide a...
