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 کاملDeranged myofilament phosphorylation and function in experimental heart failure with preserved ejection fraction.
AIMS Heart failure (HF) with preserved ejection fraction (HFpEF) is a major cause of morbidity and mortality. Key alterations in HFpEF include increased left ventricular (LV) stiffness and abnormal relaxation. We hypothesized that myofilament protein phosphorylation and function are deranged in experimental HFpEF vs. normal myocardium. Such alterations may involve the giant elastic protein titi...
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 کاملEffects of a myofilament calcium sensitizer on left ventricular systolic and diastolic function in rats with volume overload heart failure.
Aortocaval fistula (ACF)-induced volume overload (VO) heart failure (HF) results in progressive left ventricular (LV) dysfunction. Hemodynamic load reversal during pre-HF (4 wk post-ACF; REV) results in rapid structural but delayed functional recovery. This study investigated myocyte and myofilament function in ACF and REV and tested the hypothesis that a myofilament Ca(2+) sensitizer would imp...
متن کامل[Diastolic dysfunction and diastolic heart failure].
There are frequent clinical Cases in Cardiological practice when cardiac failure develops together with normal systolic function of left ventricle. In these patients after revealing the diastolic dysfunction the heart diastolic failure is diagnosed, but in frequent cases this diagnosis is based on exclusion method. According to Framingham data the number of patients with clinically manifested d...
