Two pilot studies of interleukin-1 (IL-1) blockade in ST-segment elevation myocardial infarction (STEM) showed blunted acute inflammatory response and overall favorable outcomes at 3 months follow-up. We hereby present a patient-level pooled analysis with extended follow-up of 40 patients with clinically stable STEMI randomized to anakinra, a recombinant IL-1 receptor antagonist, 100 mg/day for 14 days or placebo in a double-blinded. fashion. End points included death, cardiac death, recurrent acute myocardial infarction (AMI), stroke, unstable angina, and symptomatic heart failure. Median follow-up was 28 (interquartile range 3 to 38) months. Sixteen patients (40%) had a total of 22 adverse cardiovascular events: 1 cardiac death, 4 recurrent AMI, 5 episodes of unstable angina pectoris requiring hospitalization and/or urgent revascularization, and 11 new diagnoses of heart failure. Treatment with anakinra was associated with a hazard ratio of 1.08 (95% confidence interval 0.31 to 3.74, p = 0.90) for the combined end point of death, recurrent AMI, unstable angina pectoris, or stroke and a hazard ratio of 0.16 (95% confidence interval 0.03 to 0.76, p = 0.008) for death or heart failure. In conclusion, IL-1 blockade with anakinra for 2 weeks appears, therefore, to have a neutral effect on recurrent ischemic events, whereas it may prevent new-onset heart failure long term after STEMI.
