摘要

Background Very elderly patients (age ≥ 85 years) are a rapidly increasing segment of the population.As a group,they experience high rates of in-hospital mortality and bleeding complications following percutaneous coronary intervention (PCI).However,the relationship between bleeding and mortality in the very elderly is unknown.Methods Retrospective review was performed on 17,378 consecutive PCI procedures from 2000 to 2015 at Dartmouth-Hitchcock Medical Center.Incidence of bleeding during the index PCI admission (bleeding requiring transfusion,access site hematoma ＞ 5 cm,pseudoaneurysm,and retroperitoneal bleed) and in-hospital mortality were reported for four age groups (＜ 65 years,65-74 years,75-84 years,and ≥ 85 years).The mortality of patients who suffered bleeding complications and those who did not was calculated and multivariate analysis was performed for in-hospital mortality.Lastly,known predictors of bleeding were compared between patients age ＜ 85 years and age ≥ 85 years.Results Of 17,378 patients studied,1019 (5.9％) experienced bleeding and 369 (2.1％) died in-hospital following PCI.Incidence of bleeding and in-hospital mortality increased monotonically with increasing age (mortality:0.94％,2.27％,4.24％ and 4.58％;bleeding:3.96％,6.62％,10.68％ and 13.99％ for ages ＜ 65,65-74,75-84 and ≥ 85 years,respectively).On multivariate analysis,bleeding was associated with increased mortality for all age groups except patients age ≥ 85 years [odds ratio (95％ CI):age ＜ 65 years,3.65 (1.99-6.74);age 65-74 years,2.83 (1.62-4.94);age 75-84 years,3.86 (2.56-5.82),age ≥ 85 years:1.39 (0.49-3.95)].Conclusions Bleeding and mortality following PCI increase with increasing age.For the very elderly,despite high rates of bleeding,bleeding is no longer predictive of in-hospital mortality following PCI.
