BACKGROUND Early inflammation following acute ST-segment elevation myocardial infarction (STEMI) treated by primary percutaneous coronary intervention (PCI) affects myocardial infarct (MI) size and left ventricular remodeling. The mammalian target of rapamycin (mTOR) is involved in the enhanced inflammatory response and its inhibition has exerted beneficial effects on MI size in preclinical models of acute MI. OBJECTIVES The Controlled Level EVERolimus in Acute Coronary Syndromes trial (CLEVER-ACS) evaluated the effects of targeting inflammation by mTOR inhibition in patients with STEMI undergoing PCI. METHODS CLEVER-ACS was a randomized, multicenter, international, double-blind, placebo-controlled trial. A total of 150 patients with STEMI undergoing PCI were randomly assigned to oral everolimus (days 1-3: 7.5 mg qd, days 4-5: 5.0 mg qd) or placebo for 5 days. The primary endpoint was the change in myocardial infarct size, the secondary endpoint the change in microvascular obstruction (MVO) from baseline (12 hours - 5 days after PCI) to 30 days as assessed by cardiac magnetic resonance imaging (CMR). RESULTS The changes in MI size from baseline to 30 days, the primary endpoint, were -14.2 (95% CI -17.4 to -11.1) g and -12.3 (95% CI -16.0 to -8.7) g in the everolimus and placebo groups (p=0.99). Corresponding changes in MVO were -4.8 (-6.7 to -2.9) g and -6.3 (-8.7 to -4.0) g in the everolimus and placebo groups (p=0.14). Adverse events did not differ between the study groups. CONCLUSIONS Among STEMI patients undergoing PCI, early mTOR inhibition with everolimus did not reduce MI size or MVO at 30 days. |
