Higher regional post-MI procedure rates were not associated with better survival; leaves open questions of overuse and requires randomized confirmation.
Does a higher regional rate of cardiac procedures improve mortality or quality of life in Medicare patients after acute myocardial infarction?
A higher regional rate of coronary angiography and revascularization after acute MI was not associated with improved survival or quality of life, suggesting potential overuse without clinical benefit.
Guadagnoli et al. (1995) studied this question.
