CIRCUS Trial design: Patients with anterior STEMI were randomized to IV cyclosporine 2.5 mg/kg (n = 475) vs. placebo (n = 495) immediately before coronary reperfusion. (p = 0.77) Results All-cause death, worsening heart failure during the index hospitalization, rehospitalization for heart failure, or adverse LV remodeling within 1 year: 59.0% of the cyclosporine group vs. 58.1% of the placebo group (p = 0.77) 59.0 58.1 % Conclusions Among patients with anterior STEMI undergoing primary PCI, IV cyclosporine failed to improve clinical outcomes or prevent adverse LV remodeling Cyclosporine Placebo Cung TT, et al.
