The purpose of this study is to examine the efficacy of an intensive, supervised, lifestyle modification program on symptoms and signs of heart failure as well as laboratory and echocardiographic measures of cardiac structure and function. This will be a 6 month trial in 50 patients with a clinical diagnosis of heart failure with preserved ejection fraction (HFpEF). Patients will be enrolled in the Medical University of South Carolina weight management 15 week lifestyle change program which will involve weekly visits that rotate among the clinical specialities (dietary, exercise and behavioral) and scheduled visits with the research Registered Nurse. Each patients baseline data will be used as the control and compared with the same measurements at the 6 month end point.

Diastolic heart failure is now being recognized as a key form of heart failure in older people. The focus of this research is to study ways to improve and maintain physical activity and f...
The principle aim is to determine the efficacy of eplerenone in patients with diastolic heart failure to reverse cardiac remodeling and to improve diastolic function.
To investigate whether the medicines eplerenone or atorvastatin have a favourable effect on diastolic heart failure. Eplerenone is a drug that has been shown to be beneficial in Chronic H...
The main objective is to replicate the validation of omics biomarkers of left ventricular diastolic dysfunction in patients with metabolic syndrome. The aim was to recruit overall 750 pa...
The study is designed to define the underlying vascular abnormalities present in patients with diastolic heart failure and test the effect of a therapy aimed at vascular abnormalities. Th...
We performed a retrospective pilot study on a group of symptomatic patients attending our community heart failure clinic with left ventricular diastolic dysfunction (LVDD), rising or elevated LV end d...
Resting heart rate has long been thought to be a risk factor in cardiovascular disease and a prognostic factor in heart failure. β-Blockers were originally used in heart failure for their heart rate ...
Diastolic dysfunction (DD), a precursor to clinical heart failure (HF), has traditionally been evaluated by echocardiography. Data regarding morphological descriptions of pulmonary vein (PV) orifices ...
The ratio of transmitral early filling velocity (E) to early diastolic tissue velocity (E') is a key diastolic function parameter. The early diastolic strain rate (E'sr) has been proposed as a substit...
This study determined whether there is development of tachyphylaxis to enhancement of cardiorenal response to acute volume loading (AVL) with B-type natriuretic peptide (BNP) after 12-week, twice-dail...
Heart failure caused by abnormal myocardial relaxation during DIASTOLE leading to defective cardiac filling.
A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.
A selective beta-1-adrenergic partial agonist. Because it is a partial agonist (DRUG PARTIAL AGONISM) it acts like an agonist when sympathetic activity is low and as an antagonist when sympathetic activity is high. It reduces MYOCARDIAL ISCHEMIA and improves ventricular function in patients with mild to moderate heart failure. In patients with severe heart failure it has been shown to produce benefits in systolic and diastolic function.
Enlargement of the HEART, usually indicated by a cardiothoracic ratio above 0.50. Heart enlargement may involve the right, the left, or both HEART VENTRICLES or HEART ATRIA. Cardiomegaly is a nonspecific symptom seen in patients with chronic systolic heart failure (HEART FAILURE) or several forms of CARDIOMYOPATHIES.
Heart sounds caused by vibrations resulting from the flow of blood through the heart. Heart murmurs can be examined by HEART AUSCULTATION, and analyzed by their intensity (6 grades), duration, timing (systolic, diastolic, or continuous), location, transmission, and quality (musical, vibratory, blowing, etc).
