NCT05880355

Brief Summary

Subjects with urgently reperfused type I myocardial infarction (MI) will be recruited and randomized to receive either placebo or the oral inflammasome (NLRP3) inhibitor dapansutrile. The primarily outcome measure will be carotid plaque volume change over 6 months; secondary outcome measures will be plaque inflammatory activity and coronary microvascular function.
