BACKGROUND: Postural hypotension induced by transition from supine to sitting position and measures for its prevention in heart failure has not been investigated. OBJECTIVE: Our purpose was to evaluate the prevalence of postural hypotension and associated clinical manifestations as well as the contribution of various risk factors for postural hypotension on transition from lying to sitting in older patients with decompensated heart failure, and to study the eventual preventive effect of leg bandaging. METHODS: Seating-induced postural hypotension (>or=20 mm Hg systolic and/or >or=10 mm Hg diastolic blood pressure fall) was assessed on the first study day in 108 patients aged >or=60 years, hospitalized for acutely decompensated heart failure. On the next day, in patients manifesting postural hypotension, compression bandages were applied along both legs before seating. Blood pressure, heart rate, O(2) saturation, and the occurrence of dizziness or palpitations were recorded prior to and 1, 3 and 5 min following seating. RESULTS: Postural hypotension occurred in 49.1% of patients. Dizziness and/or palpitations manifested in 25%. Diastolic (36.1%) versus systolic (23.1%) postural hypotension prevailed (p=0.05). On univariate analysis, postural hypotension was associated with female sex (p=0.03), more severe heart failure (p=0.05), longer bedrest (p=0.04), higher supine systolic (p=0.01) or diastolic (p=0.002) blood pressure, nonischemic heart failure (p=0.002), and not using nitrates (p = 0.01). On multivariate analysis, longer bedrest (OR=1.58, 95% CI=1.13-2.2, p<0.001), higher supine diastolic blood pressure (OR=1.33, 95% CI=1.1-1.61, p=0.001), and nonischemic heart failure (OR=3.48, 95% CI=1.4-8.63, p=0.009) were the most predictive of postural hypotension. Compression bandages prevented postural hypotension in 21 of 49 patients and decreased the degree of postural blood pressure fall (p<0.001). CONCLUSION: Seating-induced postural hypotension is common among older inpatients with decompensated heart failure, especially with longer bedrest, higher supine diastolic blood pressure and non-ischemic etiology. Leg compression bandaging may be useful for the prevention of postural hypotension in these patients. Copyright 2008 S. Karger AG, Basel.
