Objectives:
The aim of this study is to summarize the outcomes of patients undergoing direct stenting (DS) with drug-eluting stents (DES) compared to those who underwent balloon predilatation.
Background:
DS has been associated with improved outcomes in the bare-metal stent era. Although DS with DES implantation has been increasingly adopted in clinical practice, its safety and effectiveness remain controversial.
Methods:
The search criteria identified 546 studies in the Medline/PubMed, Cochrane, and EMBASE databases from 2001 to July 2014. From these, seven studies totaling 10,900 patients were selected. Summarized estimates [odds ratio (OR) and 95% confidence intervals] were obtained using a random-effects model. The primary outcomes were a composite of major adverse cardiac events (MACE), including all-cause death, myocardial infarction (MI), and repeat revascularization. The secondary outcomes included a composite of death and MI and the rates of target lesion revascularization (TLR).
Results:
Overall, 4101 (38%) and 6799 (62%) patients underwent DS with DES and balloon pre-dilatation, respectively. DS with DES reduced the likelihood of MACE (OR: 0.81 [0.71-0.93]). Additionally, DS with DES was associated with reduced rates of death/MI (OR: 0.76 [0.62-0.92]), and TLR (OR: 0.66 [0.44-0.98]).
Conclusions:
DS with DES is safe and may be associated with better outcomes in selected patients. © 2016 Wiley Periodicals, Inc.
