Trends in physician management of uncomplicated acute myocardial infarction, 1970 to 1987

To document current management of uncomplicated acute myocardial infarction (AMI), a national survey of 1,065 physicians was performed. Items from previous surveys in 1970 and 1979 were included to permit analysis of time trends in management. Median hospital stay dropped from 21 days in 1970 to 9 days in 1987. Use of beta blockers and aspirin doubled between 1979 and 1987, while use of anticoagulation and sulfinpyrazone dropped 4- to 10-fold. In 1987, coronary angiography was used commonly, especially in younger patients or those with either a non-Q-wave AMI, intravenous thrombolytic therapy or a positive exercise test. These findings document the increasingly aggressive approach to the management of patients with uncomplicated AMI.
