Abstract
Our aim was to compare direct stenting (DS) with conventional stenting (CS) in patients with acute coronary syndrome (ACS). We searched PubMed, EMBASE, and ISI web of science for eligible studies. Primary end point was major adverse cardiac events (MACEs) in short term. Secondary end points were 1-year mortality and after-procedural no-reflow phenomenon. Twelve trials in 8998 patients were included. The odds ratios (ORs) were pooled using the Mantel-Haenszel fixed effect model. Short-term MACEs were significantly reduced in the DS arm in contrast to the CS (5.00% vs 8.08%, DS vs CS, respectively, OR [95% confidence interval] = 0.61 [0.46-0.80], P = .0004). One-year mortality and after-procedural no-reflow phenomenon were significantly lower in the DS group. No heterogeneity was observed through I2 test ( Phet = .81, .89, and .77 for each end point, respectively). This meta-analysis demonstrated that in selected patients with ACS, DS is not only safe and feasible but also reduces short-term and 1-year mortality as well as the occurrence of after-procedural no-reflow phenomenon.
