To determine the relationship of left ventricular function and ventricular tachycardia, 48 hour ECG monitoring and technetium-99m gated equilibrium radionuclide angiography were performed in 84 consecutive patients with hypertrophic cardiomyopathy and sinus rhythm. Measurements of ejection fraction (EF), peak ejection rate (PER, edv/s), peak filling rate (PFR, edv/s) and time to peak filling ra...
abstract background: this study sought to determine patient characteristics, process of care, and outcome as predictors of reintubation after open-heart surgery. methods: we performed a retrospective case control study that included all patients undergoing cardiac surgery who required reintubation and an equal number of control patients not requiring reintubation. putative risk factors were ana...
Background: 99mTc-MIBI cardiac perfusion scanning is recognized as a clinically useful method in evaluating coronary artery disease. By the implementation of new imaging techniques and systems, it seems possible to obtain high-quality images with a lower dose of radiopharmaceuticals. The purpose of this study was to evaluate the effect of injection dose of 99mTc-MIBI on quantitative parameters ...
AIMS This study was designed to identify the characteristics and long-term prognosis of heart failure with preserved ejection fraction (HFPEF) in patients hospitalized for a first episode of HF. METHODS AND RESULTS Consecutive patients (n = 799) hospitalized for a first episode of HF during 2000 in the Somme department (France) were recruited. EF was available in 662 (83%) patients, represent...
Global left ventricular (LV) ejection fraction (LVEF) has been used as a measure of improvement in LV function following cell therapy. Although the impact of cell therapy on LVEF in shortand long-term follow-up has been generally positive, there is concern that research evaluating regional therapeutics (e.g., cell or gene therapy) may require analysis of regional LV function localized to the si...
Background—Post–myocardial infarction global ejection fraction and infarct-related artery patency might be expected to be associated with health-related quality-of-life (HRQOL) outcomes, but this association has not been previously shown. The GUSTO-I Angiographic Study cohort 2-year follow-up afforded an examination of such potential relationships. Methods and Results—A total of 1848 patients (...
BACKGROUND Women with signs and symptoms of ischemia, no obstructive coronary artery disease (CAD) and preserved left ventricular ejection fraction (EF) often have diastolic dysfunction and experience elevated rates of major adverse cardiac events (MACE), including heart failure (HF) hospitalization with preserved ejection fraction (HFpEF). We evaluated the predictive value of inflammatory biom...
Recurrent stroke in the warfarin versus aspirin in reduced cardiac ejection fraction (WARCEF) trial.
BACKGROUND AND PURPOSE WARCEF randomized 2,305 patients in sinus rhythm with ejection fraction (EF) ≤ 35% to warfarin (INR 2.0-3.5) or aspirin 325 mg. Warfarin reduced the incident ischemic stroke (IIS) hazard rate by 48% over aspirin in a secondary analysis. The IIS rate in heart failure (HF) is too low to warrant routine anticoagulation but epidemiologic studies show that prior stroke increas...
سابقه و هدف: تفاوت روزانه در وقوع سکته حاد قلبی با حداکثر وقوع صبحگاهی آن امری شناخته شده می باشد. در مورد ایجاد اختلال عملکرد سیستولیک بطن چپ برمبنای زمان وقوع انفارکتوس اطلاعات ناچیزی در دست می باشد. باتوجه به اهمیت پیدایش نارسایی قلبی بدنبال سکته حاد قلبی ما برآن شدیم تا زمان وقوع سکته حاد قلبی بر پیدایش اختلال عملکرد سیستولیک بطن چپ را بررسی نماییم. مواد و روش ها: در یک مطالعه آینده نگر تعد...
BACKGROUND The fundamental determinant of the natural history of Chagas' disease is cardiac involvement. METHODS AND RESULTS We studied 104 male patients with congestive heart failure due to Chagas' disease to estimate the survival distribution function and to evaluate age, functional class (FC), maximal oxygen consumption (VO2max), and ejection fraction (EF) as predictors of survival. Statis...
