Pathophysiological characterization of isolated diastolic heart failure in comparison to systolic heart failure.

CONTEXT Many older patients with symptoms of congestive heart failure have a preserved left ventricular ejection fraction (LVEF). However, the pathophysiology of this disorder, presumptively termed diastolic heart failure (DHF), is not well characterized and it is unknown whether it represents true heart failure. OBJECTIVE To assess the 4 key pathophysiological domains that characterize class...

The Prevalence of Anemia in Elderly With Systolic Heart Failure

Objectives: Anemia is prevalent in heart failures and is an independent risk factor for adverse clinical outcomes in patients with CHF. The aim of the present study was to determine the prevalence of anemia in elderly with systolic heart failure hospitalized in Alborz Hospital of Karaj in 2009. Methods & Materials: This is a descriptive retrospective study that reviewed 154 medical records o...

Self-care behaviors in patients with systolic heart failure

Background and Purpose: To improve life quality, and lower mortality and rehospitalization for heart failure patients, awareness and adherence to self-care behaviors are essential. This study aims to determine the adherence level to self-care behaviors in the patients with systolic heart failure hospitalized in Alborz hospital in Karaj andShahriar hospital, and it was conducted in 2013. Methods...

Digoxin and reduction of heart failure hospitalization in chronic systolic and diastolic heart failure.

In the Digitalis Investigation Group trial, digoxin-associated decrease in the combined end point of heart failure (HF) hospitalization or HF mortality was significant in systolic but not in diastolic HF. To assess whether this apparent disparity could be explained by differences in baseline characteristics and sample size, we used propensity score matching to assemble a cohort of 916 pairs of ...

Pathophysiological role of oxidative stress in systolic and diastolic heart failure and its therapeutic implications.

Systolic and diastolic myocardial dysfunction has been demonstrated to be associated with an activation of the circulating and local renin-angiotensin-aldosterone system (RAAS), and with a subsequent inappropriately increased production of reactive oxygen species (ROS). While, at low concentrations, ROS modulate important physiological functions through changes in cellular signalling and gene e...
