Abstract
I would like to call your attention to the article by Jiang et al, “Meta-analysis of Effectiveness of First-generation Drug-eluting Stents Versus Coronary Artery Bypass Grafting for Unprotected Left Main Coronary Disease.” I have serious concerns regarding the literature search method and classification of studies included in their meta-analysis. Meta-Analysis of Effectiveness of First-Generation Drug-Eluting Stents Versus Coronary Artery Bypass Grafting for Unprotected Left Main Coronary DiseaseAmerican Journal of CardiologyVol. 110Issue 12PreviewIt is controversial whether drug-eluting stents (DESs) are safe and effective when generalized to “real-world” patients with unprotected left main coronary artery disease. This meta-analysis compared the safety and efficacy of DESs to coronary artery bypass grafting (CABG) in real-world patients with unprotected left main coronary artery. We identified comparative, observational, DES versus CABG studies published from January 2000 through May 2012. All studies included ≥100 patients and reported end points with follow-ups ≥6 months.
