BACKGROUND Obstructive sleep apnea subjects the failing heart to adverse hemodynamic and adrenergic loads and may thereby contribute to the progression of heart failure. We hypothesized that treatment of obstructive sleep apnea by continuous positive airway pressure in patients with heart failure would improve left ventricular systolic function. METHODS Twenty-four patients with a depressed l...
Systemic oxygen uptake and deep femoral vein oxygen content were determined at peak exercise in 53 patients with chronic heart failure with impaired systolic function (mean left ventricular ejection fraction 0.18; n = 41) or preserved systolic function (mean left ventricular ejection fraction 0.70; n = 12) and in 6 age-matched sedentary normal subjects. At peak exercise, deep femoral vein oxyge...
Heart failure is a descriptive clinical syndrome, which encompasses the consequences of both right and left ventricular dysfunction (systolic and non-systolic). Systolic left ventricular dysfunction, about which there is most epidemiological and experimental evidence, is a malignant disease. In a recent population based study more than one third of patients had died within 12 months of diagnosi...
OBJECTIVE To investigate the relation between plasma adrenomedullin and the severity of diastolic dysfunction in patients with heart failure. DESIGN Prospective study. SETTING University teaching hospital. PATIENTS 77 patients (mean (SEM) age 66.3 (1.2) years; 75% male) who were being followed in the outpatient clinic after admission to hospital for acute heart failure. INTERVENTIONS Sa...
