Randomized Controlled Trial Multicenter StudyStatin Recapture Therapy before Coronary Artery Bypass Grafting Trial: Rationale and study design of a multicenter, randomized, double-blinded controlled clinical trial.
Patients undergoing coronary artery bypass grafting (CABG) are still at significant risk for postoperative major adverse cardiac and cerebrovascular events (MACCEs). Recent clinical evidence shows that cardioprotection in patients receiving a chronic statin treatment can be "recaptured" by a high-dose statin therapy given shortly before an ischemia-reperfusion sequence. Evaluation of this novel therapeutic approach in the setting of CABG seems promising because myocardial ischemia-reperfusion injury plays a pivotal role in poor clinical outcomes that may be improved by a simple preoperative statin recapture treatment. ⋯ The StaRT-CABG trial is expected to provide highly relevant clinical data on the efficacy of this novel therapeutic approach to optimize the care for patients with coronary artery disease undergoing CABG.

Randomized Controlled Trial Multicenter StudyEffects of the dual peroxisome proliferator-activated receptor activator aleglitazar in patients with Type 2 Diabetes mellitus or prediabetes.
Insulin-resistant states, including type 2 diabetes (T2D) and prediabetes, are associated with elevated cardiovascular (CV) risk. Aleglitazar is a dual peroxisome proliferator-activated receptor α/γ agonist with favorable insulin-sensitizing and glucose-lowering actions, favorable effects on blood lipids, and an acceptable safety profile in short-time studies. Therefore, it was hypothesized that aleglitazar would reduce CV morbidity and mortality in patients with T2D mellitus and prediabetes (defined as glycosylated hemoglobin ≥5.7% to <6.5%) with previous CV complications. ⋯ Even within a short duration of exposure, aleglitazar was associated with excess adverse events, corroborating the findings of a larger and longer trial in T2D. Coupled with the previous failure of several other peroxisome proliferator-activated receptor α/γ activators, this class now holds little promise for CV therapeutics.
