title: Hemodynamic effect of endothelin antagonists in dogs with myocardial infarction.
abstract: The hemodynamic effects of enalapril, an angiotensin-converting enzyme inhibitor, BQ-123, a selective ETA receptor antagonist, and bosentan, a nonselective ETA and ETB receptor antagonist, were studied in dogs 4 weeks after myocardial infarction (MI) produced by ligation of the left anterior descending coronary artery. Reduced arterial pressure and total peripheral resistance after administration of analapril, BQ-123, and bosentan revealed that both the renin-angiotensin system and endothelin participate in maintenance of cardiovascular function in chronic MI.
