Acute Coronary Syndromes

results: The overall incidence of CR was 2.4% (n=135). Over 35 years, there was a linear trend increasing primary percutaneous coronary intervention (PPCI) (1st;0.3%, 2nd;33%, 3rd;67%, P<0.001). The incidence of CR in the 3rd interval was significantly lower than those in 1st and 2nd intervals (1st;2.7%, 2nd;2.7%, 3rd;1.8%, P=0.04). In the multivariate analysis (Table), female, first-AMI and older age (>70 years old) were common independent determinants among 3 intervals, although hypertension and anterior AMI became insignificant in the recent two intervals. Importantly, PPCI became a significant factor preventing CR in 3rd interval, whereas thrombolysis was insignificant in any intervals.
