Use of cardiac procedures and outcomes in elderly patients with myocardial infarction in the United States and Canada.
Tu JV et al.
N Engl J Med, 336(21):1500-5 1997 May 22.

The results of this study, conducted on approximately 234,000 elderly U.S. and Canadian individuals who had a new myocardial infarction in 1991, show that the rate of invasive revascularization procedures is almost 8-fold higher in Americans versus Canadian patients, with 11.7% and 10.6% of American patients undergoing angioplasty and bypass surgery, respectively, compared to 1.5% and 1.4% of Canadians. Although 30-days mortality rates were slightly lower in American versus Canadian patients (21.4% vs. 22.3%), 1-year death rates were practically equivalent in the two populations (34.3% vs. 34.4%), indicating that a significantly higher rate of utilization of invasive cardiac procedures and health care resources in the U.S. does not translate in improved long-term outcome in elderly individuals with acute myocardial infarction.
