Clinical trials in heart failure (HF) tend to randomize patients according to demographic characteristics and severity of left ventricular dysfunction, without taking account of the precise diagnosis. This article reviews results from recent trials suggesting that the etiology of HF, and particularly whether it is ischemic or nonischemic, may influence the long-term prognosis and the response t...
655 Heart failure (HF) is a complex syndrome in which structural or functional cardiac abnormalities impair the filling of ventricles or left ventricular ejection of blood. HF disproportionately occurs in those ≥65 years of age. Among the estimated 1.5 to 2 million residents in skilled nursing facilities (SNFs) in the United States, cardiovascular disease is the largest diagnostic category, and...
Activation of PPARs may be involved in the development of heart failure (HF). We evaluated the relationship between expression of PPARγ in the myocardium during coronary artery bypass grafting (CABG) and exercise tolerance initially and during follow-up. 6-minute walking test was performed before CABG, after 1, 12, 24 months. Patients were divided into two groups (HF and non-HF) based on left v...
2 MeV He+ backscattering spectrometry and x-ray diffraction have been used to study HfSi2 formed by thermal annealing of a Hf Si film on evaporated Si (Si•) at temperatures between 575 and 650 ·c. A laterally uniform layer of Hf Si2 forms and its thickness is proportional to the square root of time at a fixed temperature. The activation energy of this reaction is found to be 3.5 ± 0.3 eV. This ...
We investigated the impact of a high-fat (HF) diet during pre- and post-weaning periods on the intestinal microbiota and alkaline phosphatase (AP) activity in male rats. Nutrition from birth was influenced by feeding rat dams with either a standard or HF diet. After weaning male pups nursed by control dams continued on a standard diet (CC) or HF diet (C->HF), while offspring nursed by HF dams c...
سابقه و هدف: امروزه با پیشرفت علم دندانپزشکی و تمایل بیشتر بیماران برای حفظ دندانهایشان، دندانهایی با روکش پرسنلی متداول شده و از آنجا که قدرت باند کامپوزیت با پرسلن ضعیف می باشد این تحقیق با هدف مقایسه باند یک نوع کامپوزیت تجاری (one coat bond) با تکنیک acid etch پرسلن بهمراه کامپوزیت self cure معمولی انجام گرفت. مواد و روشها: مطالعه به روش تجربی و با استفاده از تکنیک مشاهده بر روی 40 بلوک پرس...
Background Characterizing myocardial mechanical properties is valuable in understanding cardiomyopathy with and without clinical heart failure (HF). We sought to examine the incremental value of strain assessment in patients with left ventricular systolic dysfunction without HF (LVSD), HF with reduced ejection fraction (HFrEF), LV diastolic dysfunction without HF (LVDD) and HF with preserved EF...
Introduction: Medication adherence is essential to improve outcomes emanated from the disease. The increase in the complexity of the medical regimens causes poor adherence in patients with heart failure; also, the progressive nature of Heart Failure (HF) and its complicated drug regimens are mostly stressful. This study has been conducted on the HF patients at the heart hospital of Kermanshah c...
BACKGROUND We evaluated the effects of endurance exercise and a high-fat diet on insulin resistance and ceramide contents of skeletal muscle in Sprague-Dawley rats. METHODS We randomly divided 32 rats into four groups: control (CON, n = 8), high fat diet (HF, n = 8), exercise (Ex, 24 m/min for 2 hours, 5 days/wk, n = 8), HF/Ex (n = 8). After 4-week treatments, plasma lipid profiles, glucose a...
Maternal high-fat (HF) diet has long-term consequences on the metabolic phenotype of the offspring. Here, we determined the effects of postweaning exercise in offspring of rat dams fed HF diet during gestation and lactation. Pregnant Sprague-Dawley rats were maintained on chow or HF diet throughout gestation and lactation. All pups were weaned onto chow diet on postnatal day (PND) 21. At 4 wk o...
