We examined the hemodynamic effects of congesting cuffs (rotating tourniquets) in 12 patients with first acute myocardial infarction and new onset of congestive heart failure 24 to 48 hours after admission. Congesting cuffs were applied for two periods of 15 minutes each, 15 minutes apart, and inflated to 30 mm Hg and 60 mm Hg consecutively. No change was noticed in mean pulmonary artery wedge pressure, which was 20 +/- 3 mm Hg at the beginning of the study and 19 +/- 3 mm Hg at the completion (P greater than .05, NS), nor in other hemodynamic and blood gases parameters. Patients’ clinical conditions remained unchanged. We conclude that application of congesting cuffs at pressures of 30 mm Hg and 60 mm Hg does not result in any change in clinical or hemodynamic data in patients with acute myocardial infarction and new onset of congestive heart failure.
