Diastolic Function in Heart Failure
Heart failure has reached epidemic proportions, and diastolic heart failure or heart failure with preserved ejection fraction (HFpEF) constitutes about 50% of all heart failure admissions. Long-term prognosis of both reduced ejection fraction heart failure and HFpEF are similarly dismal. No pharmacologic agent has been developed that actually treats or repairs the physiologic deficit(s) respons...
متن کاملLeft atrial function in diastolic heart failure.
BACKGROUND Abnormalities in left ventricular (LV) structure and function occur in patients with diastolic heart failure (DHF). The reasons for the transition from asymptomatic dysfunction to heart failure need better definition, including noninvasive measurements that can detect the transition. METHODS AND RESULTS In 64 patients undergoing right heart catheterization, simultaneous echocardiog...
متن کاملDiastolic function of the heart in untreated primary hypertension.
To study left ventricular (LV) diastolic function of the heart in relation to blood pressure (BP) and other signs of hypertensive cardiac and peripheral vascular changes, isovolumic relaxation time and early diastolic filling were determined in four BP groups of untreated 49-year-old men: normotensive subjects (n = 20), men with borderline hypertension (n = 30), mild hypertension (n = 45), and ...
متن کاملThe effect of acute allergic reactions on diastolic heart function.
PURPOSE Diastolic heart failure is characterized by the presence of heart failure symptoms despite preserved systolic function. Cytokines released during allergic reactions may impair diastolic heart function, either through their direct toxic effects or by inducing coronary artery spasm. The purpose of this study was to examine the effects of acute allergic reactions on diastolic heart functio...
متن کاملThe role of left atrial function in diastolic heart failure.
New heart failure affects 500 000 Americans yearly. Nearly 50% of these patients have a normal left ventricular ejection fraction (LVEF) or so-called diastolic heart failure (DHF). New onset symptomatic DHF is a lethal disease with a 5-year mortality that approaches 50%.1 EchoDoppler techniques use LV filling patterns and tissue Doppler imaging of the mitral annulus to help identify and classif...
