Abstract

Acute coronary syndromes (ACS) in patients with diabetes mellitus (DM) are associated with a high risk for major adverse cardiovascular events (MACEs) despite statin treatment. The impact of combined bezafibrate and statin therapy in patients with DM and ACS has not been specifically investigated. The aim of this study was to evaluate the association of combined therapy with 30-day MACEs in patients with DM participating in the nationwide Acute Coronary Syndrome Israeli Surveys (ACSIS). The study population comprised 3,063 patients with DM from the ACSIS 2000, 2002, 2004, 2006, 2008, and 2010 enrollment waves who were alive at discharge and received statins. Of these, 225 (7.3%) received on discharge combined bezafibrate and statin therapy, and 2,838 (92.7%) were treated with statins alone. MACEs were defined as a composite measure of death, recurrent myocardial infarction, recurrent ischemia, stent thrombosis, ischemic stroke, and urgent revascularization. The development of 30-day MACEs was recorded in 8% patients receiving combination therapy and 14.2% of those receiving statins alone (p = 0.01). Crude 1-year mortality and 30-day rehospitalization rates were also significantly lower in patients receiving combination therapy: 4.0% versus 8.1% (p = 0.03) and 13.3% versus 21.6% (p = 0.003), respectively. Multivariate analysis identified combined therapy as an independent predictor of reduced risk for 30-day MACEs, with an odds ratio of 0.56 (95% confidence interval 0.34 to 0.92), corresponding to a 44% relative risk reduction. In conclusion, a significantly lower risk for 30-day MACEs was observed in statin-treated patients with DM who also received bezafibrate after ACS. Signals regarding improvement of 30-day rehospitalization and 1-year mortality rates emerged as well.
