To compare the long-term prognosis of a group of patients treated by an early invasive approach after a non-Q-wave anterior wall acute myocardial infarction (AMI) with a similar group treated conservatively, data from 110 consecutive patients with non-Q-wave AMI were retrospectively obtained from 3 different hospitals: (1) a hospital with coronary angioplasty and coronary bypass facilities favoring an early invasive approach, (2) a hospital with a catheterization laboratory and no coronary angioplasty or coronary bypass facilities, and (3) a community hospital without a catheterization laboratory. Patients were divided according to the presence or absense of an early invasive approach: those who had undergone in-hospital catheterization and revascularization (n = 55) and those with a conservative approach (n = 55). The early invasive approach resulted in a significant decrease in major events. The rate of recurrent myocardial infarction was 29% in the conservative group versus 7.2% in the invasive group (p = 0.025). Survival rate curves at 3-year follow-up showed significant differences in mortality (p = 0.001), recurrent myocardial infarction (p = 0.002), recurrent angina pectoris (p = 0.001), and development of congestive heart failure (p = 0.05). Multivariate analysis disclosed the early invasive approach to be an independent predictor for decreasing the likelihood of recurrent infarction by 86% (odds ratio 0.14, confidence intervals 0.04 to 0.48, p = 0.0006), and for decreasing the likelihood of recurrent angina by 66% (odds ratio 0.34, confidence intervals 0.18 to 0.63, p < 0.005). The early invasive strategy may result in an improved outcome in the treatment of patients with non-Q-wave anterior wall AMI compared with patients treated conservatively.
