Gender differences of in-hospital outcomes in patients undergoing percutaneous coronary intervention in the drug-eluting stent era.

ABSTRACT: Most studies on gender difference of the in-hospital outcome of percutaneous coronary intervention (PCI) were performed in the pre-drug-eluting stents (DES) era. This study was performed to investigate whether gender influences the in-hospital outcome of PCI in the DES era.A total of 44,967 PCI procedure between January and December of 2014 from the nationwide PCI registry database in Korea were analyzed. The study population was male predominant (70.2%). We examined the association of gender with unadjusted and adjusted in-hospital mortality and composite events of PCI, including mortality, nonfatal myocardial infarction, stent thrombosis, stroke, urgent repeat PCI and bleeding requiring transfusion.Most of the study patients (91.3%) received DES. The incidence rates of in-hospital mortality (2.95% vs 1.99%, P?<.001) and composite events (7.01% vs 5.48%, P?<.001) were significantly higher in women compared to men. Unadjusted analyses showed that women had a 1.49 times higher risk of in-hospital mortality and a 1.30 times higher risk of composite events than men (P?<.001 for each). After adjustment for potential confounders, female gender was not a risk factor for mortality (P?=?.258), but the risk of composite events remained 1.20 times higher in women than in men (P?=?.008).Among patients undergoing PCI in the contemporary DES era, female gender was associated with an increased risk of in-hospital composite events, but not in-hospital mortality. More careful attention should be emphasized to minimize procedure-related risks and to improve prognosis in women undergoing PCI.

Project description:BackgroundDrug-eluting stents (DESs) were considered as ground-breaking technology promising to eradicate restenosis and the necessity to perform multiple revascularization procedures subsequent to percutaneous coronary intervention. Soon after DESs were released on the market, however, there were reports of a potential increase in mortality and of early or late thrombosis. In addition, DESs are far more expensive than bare-metal stents (BMSs), which has led to their limited use in many countries. The technology has improved over the last few years with the second generation of DESs (DES-2). Moreover, costs have come down and an improved safety profile with decreased thrombosis has been reported.ObjectivePerform a cost-benefit analysis of DES-2s versus BMSs in the context of a publicly funded university hospital in Quebec, Canada.MethodsA systematic review of meta-analyses was conducted between 2012 and 2016 to extract data on clinical effectiveness. The clinical outcome of interest for the cost-benefit analysis was target-vessel revascularization (TVR). Cost units are those used in the Quebec health-care system. The cost-benefit analysis was based on a 2-year perspective. Deterministic and stochastic models (discrete-event simulation) were used, and various risk factors of reintervention were considered.ResultsDES-2s are much more effective than BMSs with respect to TVR rate ratio (i.e., 0.29 to 0.62 in more recent meta-analyses). DES-2s seem to cause fewer deaths and in-stent thrombosis than BMSs, but results are rarely significant, with the exception of the cobalt-chromium everolimus DES. The rate ratio of myocardial infraction is systematically in favor of DES-2s and very often significant. Despite the higher cost of DES-2s, fewer reinterventions can lead to huge savings (i.e., -$479 to -$769 per patient). Moreover, the higher a patient's risk of reintervention, the higher the savings associated with the use of DES-2s.ConclusionDespite the higher purchase cost of DES-2s compared to BMSs, generalizing their use, in particular for patients at high risk of reintervention, should enable significant savings.
