Data from patients who had ST-elevation acute myocardial infarction and renal failure and were enrolled in the 2002 Acute Coronary Syndrome Israeli Survey (ACSIS) were studied to determine the effect of different myocardial reperfusion modalities on short- and long-term outcomes. Thirty-day crude mortalities were 8.3% in the thrombolysis group, 40.0% in the primary percutaneous coronary intervention group, and 29.7% in the no-reperfusion group (p = 0.03). Crude and adjusted mortality odds ratios that were observed at 7, 30, and 365 days, with the thrombolysis group as the reference, were 3.1 to 8.1 in the percutaneous coronary intervention group and 1.5 to 4.6 in the no-reperfusion group. Our results suggest that thrombolysis may represent the preferred modality of reperfusion therapy in patients with renal failure and ST-elevation acute myocardial infarction. A large randomized prospective study is needed to confirm these results.
