Prolonged Mean Vo 2 Response Time in Systolic Heart Failure

Prolonged mean VO2 response time in systolic heart failure: an indicator of impaired right ventricular-pulmonary vascular function.

BACKGROUND In patients with left ventricular systolic dysfunction (LVSD), the rate at which oxygen uptake (VO2) increases on initiation of exercise is inadequate to match metabolic demands. To gain mechanistic insights into delayed VO2 kinetics in LVSD, we simultaneously assessed hemodynamic measurements, ventilatory parameters, and peripheral oxygen usage during exercise. METHODS AND RESULTS...

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...

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...

Systolic time intervals in heart failure in man.

Systolic Heart Failure

Copyright © 2010 Massachusetts Medical Society. A 74-year-old man with a history of hypertension and myocardial infarction that occurred 5 years previously presents with breathlessness on exertion. His current medications include a statin and aspirin. On examination, his pulse is 76 beats per minute and regular, and his blood pressure is 121/74 mm Hg. There is jugular venous distention, lateral...
