Treatment of acute myocardial infarction by primary coronary angioplasty or intravenous thrombolysis in the "real world" - One-year results from a nationwide French survey

Background-Recent randomized trials comparing primary coronary angioplasty and intravenous thrombolysis at the acute stage of myocardial infarction ha ve shown a limited but definite advantage for primary angioplasty. The aim of this study was to document 1-year outcome in patients receiving either t hrombolysis or primary angioplasty for acute myocardial infarction in the " real world." Methods and Results-We used a nationwide prospective registry of all patien ts admitted for acute myocardial infarction in French intensive care units in November 1995. Of the 721 patients who received reperfusion therapy, 152 were treated with primary angioplasty and 569 received intravenous thrombo lysis. The two groups were remarkably similar with respect to all baseline descriptors, except that a higher proportion of patients in the angioplasty group had a history of cerebrovascular accident (10% versus 2%, P<0.01), I n-hospital outcome was not different in the 2 groups. One-year survival was 85.5% in the angioplasty group and 89.5% in the thrombolysis group (P=0.18 ), Multivariate analysis showed that older age, anterior location of infarc tion, female sex, and history of heart failure were related to 1-year morta lity. In patients alive on day 5, the use of primary angioplasty and higher Killip class were additional adverse prognostic indicators. Conclusions-The results of this large registry of real-world practice indic ate no survival benefit for patients treated with primary angioplasty compa red with those who received thrombolytic therapy.
