Safety and efficacy of second-generation drug-eluting stents compared with bare-metal stents: An updated meta-analysis and regression of 9 randomized clinical trials.

ABSTRACT: The efficacy of second-generation drug-eluting stents (DES; eg, everolimus and zotarolimus) compared with bare-metal stents (BMS) in patients undergoing percutaneous coronary intervention was challenged recently by new evidence from large clinical trials. Thus, we aimed to conduct an updated systematic review and meta-analysis of randomized clinical trials (RCTs) evaluating the efficacy and safety of second-generation DES compared with BMS. Electronic databases were systematically searched for all RCTs comparing second-generation DES with BMS and reporting clinical outcomes. The primary efficacy outcome was major adverse cardiac events (MACE); the primary safety outcome was definite stent thrombosis. The DerSimonian and Laird method was used for estimation of summary risk ratios (RR). A total of 9 trials involving 17 682 patients were included in the final analysis. Compared with BMS, second-generation DES were associated with decreased incidence of MACE (RR: 0.78, 95% confidence interval [CI]: 0.69-0.88), driven by the decreased incidence of myocardial infarction (MI) (RR: 0.67, 95% CI: 0.48-0.95), target-lesion revascularization (RR: 0.47, 95% CI: 0.42-0.53), definite stent thrombosis (RR: 0.57, 95% CI: 0.41-0.78), and definite/probable stent thrombosis (RR: 0.54, 95% CI: 0.38-0.80). The incidence of all-cause mortality was similar between groups (RR: 0.94, 95% CI: 0.79-1.10). Meta-regression showed lower incidences of MI with DES implantation in elderly and diabetic patients (P?=?0.026 and P?

Project description:ObjectivesTo assess patients' perspective about factors associated with stent choice.BackgroundDrug eluting stents (DES) markedly reduce the risk of repeat percutaneous coronary intervention (PCI), but necessitate a longer duration of dual anti-platelet therapy (DAPT) as compared with bare metal stents (BMS). Thus, understanding patients' perspective about factors associated with stent choice is paramount.MethodsPatients undergoing angiography rated, on a 10-point scale, the importance (1 = not important, 10 = most important) of avoiding repeat revascularization and avoiding the following potential DAPT drawbacks: bleeding/bruising, more pills/day, medication costs and delaying elective surgery. The factor, or group of factors, that was rated highest by each patient was identified.ResultsAmong 311 patients, repeat revascularization was the single most important consideration to 14.4% of patients, while 20.6% considered avoiding one of the DAPT drawbacks as most important. Most patients (65%) considered avoiding at least one DAPT drawback as important as avoiding repeat revascularization. In no subgroup of patients did more than a quarter of patients prefer avoiding repeat revascularization above all other concerns. Among patients undergoing PCI, more than three quarters received a DES, regardless of their stated preferences (DES use among those most valuing DES benefits, avoiding DAPT drawbacks, or both equally were 78.7%, 86.2%, and 85.6%, respectively, P = 0.56).ConclusionMost patients reported that avoiding DAPT drawbacks was as important as avoiding repeat revascularization. Eliciting patient preferences regarding stent type can enhance shared decision-making and allow physicians to better tailor stent choice to patients' goals and values.Trial registrationDeveloping and Testing a Personalized Evidence-based Shared Decision-making Tool for Stent Selection (DECIDE-PCI).
