Objectives: To evaluate clinical reinfarction during a 3-year follow-up after randomization to primary angioplasty versus fibrinolysis in anterior and non-anterior ST elevation myocardial infarction (STEMI). Methods: Clinical reinfarction was prospectively assessed by an endpoint committee blinded to the study treatment. Results: At 30 days, primary angioplasty compared with fibrinolysis reduced the reinfarction rate both in anterior STEMI patients (n = 823; 2.5 vs. 5.6%, p = 0.02) and in non-anterior STEMI patients (n = 743; 0.8 vs. 7.4%, p < 0.001). After 3 years, the reduction in reinfarction rate was no longer present in anterior STEMI patients (11.2 vs. 11.2%, p = 0.86), but persisted in non-anterior STEMI patients (5.2 vs. 13.5%, p < 0.001). Reinfarction after anterior STEMI carried a higher mortality than reinfarction after non-anterior STEMI (37.6 vs. 15.3%, p = 0.01). Independent predictors of death were: age [hazard ratio (HR) per 1-year increase in age = 1.08 (1.07-1.09)], clinical reinfarction [HR = 5.15 (3.57-7.43)], anterior index STEMI [HR = 1.65 (1.24-2.19)], and Killip class ≥2 [HR = 1.42 (1.01-2.00)]. The additional late reinfarctions after angioplasty for anterior STEMI were located within the angioplasty-treated target segment. Anterior STEMI patients had smaller mean target vessel diameter, which was associated with reinfarction. Conclusions: Clinical reinfarction is an independent predictor of death. The early superiority of primary angioplasty over fibrinolysis on reinfarction rate after anterior STEMI diminished during long-term follow-up.
