To validate ejection fraction (EF) calculations from 5 and 2 minutes of multiple-gated equilibrium radionuclide angiographic data and to establish its utility during alterations in cardiac performance, we studied 38 patients with chest pain suggestive of coronary artery disease. Twenty-four patients underwent contrast ventriculography (CV) as well as first-pass (FP) and equilibrium (EQ) radionu...

Background Left ventricular (LV) and right ventricular (RV) systolic performance, typically measured as the ejection fraction (EF), is strongly correlated with mortality. However, CMR provides multiple measures that may also reflect systolic performance including LV volumes and cardiac outflow. We examined the predictive relationship of multiple potential measures of cardiac systolic performanc...

Background Heart failure (HF) patients present with a spectrum of phenotypes, including preserved ejection fraction (HFpEF) and reduced EF (HFrEF). The underlying mechanisms of HFpEF and HFrEF may be related to mechanical factors such as stiffness and stress. This study aimed to quantify passive mechanical properties in HFrEF and HFpEF patients using personalised left ventricular (LV) biomechan...

KEY CLINICAL MESSAGE A 50-year-old lady presented with epigastralgia, electrocardiogram (ECG) showed T-wave inversions and the echocardiogram low ejection fraction (EF) with apical ballooning. An esophagogastroduodenoscopy (EGD) revealed gastritis. She recovered with proton pump inhibitors treatment. This is the first case that describes gastritis-induced stress cardiomyopathy. Clinicians shoul...

Introduction MVP is a common disorder affecting 2-3% of the general population. MVP patients with severe MR may remain asymptomatic for a number of years; however, LV systolic function may be impaired post-operatively, even among those with normal pre-operative ejection fraction (EF). Myocardial strain is the assessment of myocardial local deformation and may provide a more accurate assessment ...

conclusions male gender, history of hypertension, high nyha score, and the presence of cad predict lvef deterioration in patients with lbbb. objectives the present study aimed to identify underlying factors that predict left ventricular ejection fraction (lvef) deterioration in patients suffered from complete lbbb. patients and methods in a retrospective case-control study, the data of 220 cons...

OBJECTIVES On-pump beating heart technique for myocardial revascularization has been used successfully among both low and high risk patients. Its application among low ejection fraction patients is limited. The aim of our study is to evaluate this technique among patients with low ejection fraction and to compare results with off-pump bypass technique. METHODS This retrospective study include...

BACKGROUND Aortic stenosis (AS) is becoming increasingly common with the aging population. Many of these patients have reduced left ventricular (LV) ejection fractions (EF) or low transvalvular gradients resulting in reluctance to offer aortic valve replacement (AVR). METHODS Our echocardiographic database for the period of 1993 to 2003 was screened for severe AS (aortic valve area [AVA] </= ...
