BACKGROUND Although beta blockers (BBs) are established therapy in heart failure, some patients whose left ventricular ejection fraction (LVEF) initially increases on BB therapy experience a subsequent LVEF decline. This study aimed to evaluate the proportion of patients with non-ischemic cardiomyopathy (NICM) whose LVEF declines while on BB therapy and determine important predictors of LVEF de...
conclusion the cv value correlated more closely with low lvef and more accurately indicated an enlarged heart than ca or ctr. this may be due to the fact that an anteroposterior measurement of heart size is included in the former but not the latter two measurements. these study results may help quantify left heart enlargement with greater accuracy than may be obtained from standard cxr. backgro...
AIMS The prognostic values of left ventricular ejection fraction (LVEF) during heart failure (HF) with acute decompensation or after optimal treatment have not been extensively studied. We hypothesized that posttreatment LVEF has superior predictive value for long-term prognosis than LVEF at admission does. METHODS AND RESULTS In Protocol 1, 428 acute decompensated HF (ADHF) patients with LVE...
Background and purpose: Annually heart failure includes about three million emergency outpatient visits in the United States. In heart failure NT-proBNP will be released in response to increased myocardial stretch Materials and methods: This study was conducted in 80 individuals attending Fatemeh Zahra Hospital, in Sari, 2010-2011. Patients with GFR≤60, age≥75, atrial fibrillation (AF) and hyp...
BACKGROUND A new non-linear approach was applied to calculate the left ventricular ejection fraction (LVEF) using multigated acquisition (MUGA) images. METHODS In this study, 50 patients originally for the estimation of the percentage of LVEF to monitor the effects of various cardiotoxic drugs in chemotherapy were retrospectively selected. All patients had both MUGA and echocardiography exami...
We aimed to evaluate levels of amino-terminal pro-brain natriuretic peptid (NT-proBNP) in prediction of left ventricular ejection fraction (LVEF) in heart failure patients. Prospective study on 60 consecutive patients with symptoms and signs of heart failure was performed. Blood samples for NT-proBNP analysis was taken from all test subjects and echocardiography was also done in all of them. Ac...
introduction: the correlation between right and left ventricular ejection fractions (rvef and lvef, respectively) has been studied in only a small number of patients with a marked decrease in rvef and lvef. the aim of the present study was to compare lvef and rvef in patients with ischemic heart disease. rvef and lvef were measured by cardiovascular magnetic resonance (cmr) imaging. materials a...
background: acute myocardial infarction (ami) is the leading cause of disability and death in iran and many other countries. objective: to investigate the prognostic value of ccl5 and ccl18 in patients with acute myocardial ischemia. methods: in this cohort study we recruited and followed 50 patients with acute anterior myocardial infarction (aami) for developing cardiovascular accidents in a 6...
The impact of heart failure with preserved left ventricular ejection fraction (LVEF) on activated hemostasis is still unclear. We sought to compare the activation of hemostasis in patients with heart failure with preserved LVEF, with impaired LVEF, and in healthy controls. Biomarkers of coagulation and fibrinolysis (D-dimer, tPA and PAI-1) were determined in outpatients with chronic stable (NYH...
BACKGROUND Patients with recovery of left ventricular ejection fraction (LVEF) remain at risk for future deterioration of LVEF. However, there are no tools to risk stratify these patients. We hypothesized that global longitudinal strain (GLS) could predict sustained recovery within this population. METHODS AND RESULTS We retrospectively identified 96 patients with a reduced LVEF <50% (screeni...
