We performed a meta-analysis of randomized controlled trials to compare coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) for the treatment of de novo unprotected left main disease. ⋯ In this largest series of randomized patients with unprotected left main stenosis to date, the risk of death and myocardial infarction was comparable between CABG and PCI. However, patients undergoing CABG had a higher risk of stroke, whereas patients undergoing PCI were at a higher risk for repeat revascularization.

Review Meta Analysis
[Effects of thiazolidinediones on dyslipidemia in patients with type 2 diabetes. Are all equally vasoprotective?].
Patients with type 2 diabetes face a high risk of cardiovascular morbidity and mortality. In these patients a whole cluster of cardiovascular risk factors is found, with insulin resistance being the most significant. Thiazolidinediones, in activating the peroxisome proliferator-activated receptor gamma, lower the insulin resistance. ⋯ The correlation of improved dyslipidemia, reconfirmed by PROactive, and cardiovascular prevention is yet to be resolved. However, as long as the vascular protective mechanism of pioglitazone is not conclusively resolved, findings may not be transmitted to other thiazolidinediones. For these substances, results from major outcome studies are to be required that prove a reduction of the cardiovascular risk.
