BACKGROUNDExperimental and clinical evidence suggests that cyclosporine may attenuate reperfusion injury and reduce myocardial infarct size. We aimed to test whether cyclosporine would improve clinical outcomes and prevent adverse left ventricular remodeling. METHODSIn a multicenter, double-blind, randomized trial, we assigned 970 patients with an acute anterior ST-segment elevation myocardial infarction (STEMI) who were undergoing percutaneous coronary intervention (PCI) within 12 hours after symptom onset and who had complete occlusion of the culprit coronary artery to receive a bolus injection of cyclosporine (administered intravenously at a dose of 2.5 mg per kilogram of body weight) or matching placebo before coronary recanalization. The primary outcome was a composite of death from any cause, worsening of heart failure during the initial hospitalization, rehospitalization for heart failure, or adverse left ventricular remodeling at 1 year. Adverse left ventricular remodeling was defined as an increase of 15% or more in the left ventricular end-diastolic volume. RESULTSA total of 395 patients in the cyclosporine group and 396 in the placebo group received the assigned study drug and had data that could be evaluated for the primary outcome at 1 year. The rate of the primary outcome was 59.0% in the cyclosporine group and 58.1% in the control group (odds ratio, 1.04; 95% confidence interval, 0.78 to 1.39; P = 0.77). Cyclosporine did not reduce the incidence of the separate clinical components of the primary outcome or other events, including recurrent infarction, unstable angina, and stroke. No significant difference in the safety profile was observed between the two treatment groups. CONCLUSIONSIn patients with anterior STEMI who had been referred for primary PCI, intravenous cyclosporine did not result in better clinical outcomes than those with placebo and did not prevent adverse left ventricular remodeling at 1 year.

Although many advances have been made in the development of methods to reopen the culprit coronary artery and prevent reocclusion, there is currently no specific treatment that targets myocardial reperfusion injury, which is a paradoxical form of myocardial damage that occurs as a result of the restoration of vessel patency.2 Growing evidence from experimental studies and small-size proof-of-concept clinical trials shows that reperfusion injury contributes greatly to the final infarct size.3-5 Preclinical studies indicate that the opening of the mitochondrial permeability transition pore (PTP) in the inner mitochondrial membrane plays a major role in reperfusion injury. ...

This prospective registry reflects the real-life experience of transcatheter aortic valve implantation in high-risk elderly patients in France. The early results are satisfactory in terms of feasibility, short-term haemodynamic and functional improvement, and safety. Longer term follow-up will be further assessed.

Rates of bleeding and thrombotic events were not significantly different according to 6- versus 24-month DAPT after PCI with new-generation DES in good aspirin responders. (Is There A LIfe for DES After Discontinuation of Clopidogrel [ITALICplus]; NCT01476020).
