PURPOSE: The purpose of the study was to evaluate parameters that characterize patients with myocardial reinfarction as compared to patients with a first infarction in clinical practice, and possibly to determine their clinical outcome. METHODS: The 60 minutes Myocardial Project is a German multicentre prospective observational study in which 136 hospitals are participating. Fourteen thousand, nine hundred and eighty consecutive patients with acute Q wave myocardial infarction were included from July 1992 to September 1994. RESULTS: Out of these 14,980 patients, there were 2854 (19%) with reinfarction and 12,126 (81%) with a first infarction. Patients with a reinfarction arrived at the hospital 24 min earlier than patients with a first infarction (pre-hospital delay 156 vs 180 min; P < 0.001); the door-to-needle time with reinfarction was longer (38 vs 30 min; P < 0.001); however, patients with reinfarction were older (69 vs 66 years; P < 0.001), had a lower rate of a diagnostic first ECG (54 vs 71%; P < 0.001) and received thrombolytic therapy less frequently than patients with a first infarction (46 vs 52%; P < 0.001). A low number of patients received primary PTCA ( n = 205) since only a few hospitals offered a primary PTCA service at the time the study was performed. In patients with reinfarction, there were more reasons as to why thrombolytic therapy was not given (24 vs 21%; P < 0.001). Left bundle branch block occurred more frequently in patients with reinfarction (15 vs 8%; P < 0.001). The intra-hospital course in patients with reinfarction was associated with an increase of complications and intra-hospital death (23 vs 15%; P < 0.001. CONCLUSIONS: Although reinfarction patients arrived earlier at hospital than patients with a first infarction, the former received thrombolytic therapy less frequently than the latter. Patients with reinfarction were older, more frequently had a non-diagnostic ECG on admission and had a higher rate of contraindications against thrombolytic therapy.
