Aim: Few multicenter studies have assessed the effects of angiotensin receptor blockers on cardiovascular events after drug-eluting stent implantation in patients with ischemic heart disease.<BR>Methods: An open-label multicenter randomized prospective study is in progress to evaluate the effects of candesartan on cardiovascular events in patients with ischemic heart disease after implantation of sirolimus- and/or paclitaxel-eluting stents.<BR>Results: A total of 1,145 patients were enrolled at 39 institutes in the Candesartan for prevention of Cardiovascular events after CYPHER or TAXUS Coronary stenting (4C trial). Patients were randomized into a group treated with candesartan (n=602) and a group treated with standard medical therapy without candesartan (n=543). The primary endpoint of the 4C trial is a composite of all-cause death, successful resuscitation after cardiopulmonary arrest and cardiovascular events including non-fatal myocardial infarction, unstable angina requiring emergent hospitalization, congestive heart failure requiring emergent hospitalization and cerebrovascular attacks. All patients will be followed-up for 36 months.<BR>Conclusions: The 4C trial will be the first multicenter study to elucidate the effects of candesartan after drug-eluting stent implantation and may provide new information to optimize medical therapy after percutaneous coronary interventions.
