BACKGROUND AND PURPOSE In heart failure (HF), left ventricular ejection fraction (LVEF) is inversely associated with mortality and cardiovascular outcomes. Its relationship with stroke is controversial, as is the effect of antithrombotic treatment. We studied the relationship of LVEF with stroke and cardiovascular events in patients with HF and the effect of different antithrombotic treatments....
BACKGROUND Extensive left ventricular (LV) remodeling may not allow functional recovery after revascularization, despite the presence of viable myocardium. METHODS AND RESULTS Seventy-nine consecutive patients with ischemic cardiomyopathy (left ventricle ejection fraction [LVEF] 29+/-7%) underwent surgical revascularization. Before revascularization, viability was assessed by metabolic imagin...
BACKGROUND The primary objective of primary percutaneous coronary intervention (pPCI) in patients with acute ST-segment elevation myocardial infarction (STEMI) is not only to restore the blood flow in the infarct-related artery, but also to save the patients' quality and duration of their life. Since left ventricular ejection fraction (LVEF) is a known predictor of clinical outcomes in STEMI pa...
BACKGROUND The factors that predict recovery of left ventricular (LV) systolic dysfunction among patients with atrial fibrillation (AF) are not completely understood. Late gadolinium enhancement (LGE) of the LV has been reported among patients with AF, and we aimed to test whether the presence LGE was associated with subsequent recovery of LV systolic function among patients with AF and LV dysf...

Tel: (886)7-3121101 ext. 7152, Fax: (886)73117521, E-mail: [email protected] Purpose: The aim of this study was to compare the estimated LVEF be...
OBJECTIVES This investigation sought to study the incremental value of gated rubidium (Rb)-82 positron emission tomography (PET) myocardial perfusion imaging (MPI) over clinical variables for predicting survival and future cardiac events. BACKGROUND The prognostic value of Rb-82 PET-MPI and left ventricular ejection fraction (LVEF) reserve (stress minus rest LVEF) is not well defined. METHO...
AbstractObjectives: This research was carried out to investigate the relationship between depression and left ventricular ejection fraction (LVEF) after Myocardial Infarction (MI). Method: In a prospective study 176 patients aged between 32 and 84 with a mean age of 56 years (SD 10.05) who were admitted with a diagnosis of MI to coronary care unit (CCU) in the city of Isfahan during the first f...
OBJECTIVES The aim of this study was to analyse baseline characteristics and outcome of patients with heart failure and mid-range left ventricular ejection fraction (HFmrEF, left ventricular ejection fraction (LVEF) 40%-49%) and the effect of 1-year change in LVEF in this group. SETTING Multicentre prospective observational study of ambulatory patients with HF followed up at four university h...
The aim of this study was to compare the correlation and consistency of left ventricular ejection fraction (LVEF) obtained by ECG-gated myocardial perfusion SPET (GMPS) using the four formulas (R0-R3) in ECToolbox software and by equilibrium radionuclide ventriculography (ERNV), and determine the optimal diagnostic thresholds of the four formulas in a Chinese population. A hundred and three can...
Background: In hemodialysis patients, parathyroid hormone is considered a risk factor of cardiovascular disease. Moreover, cardiovascular disease is the leading cause of mortality in hemodialysis patients. The aim of this study was to assess the effect of parathyroidectomy on cardiac performance in hemodialysis patients. Methods: This is a single hospital retrospective analysis on fifteen hemod...
