In-hospital outcome in octogenarians with XXXX undergoing emergent coronary angiography.

Very elderly @entity1 have higher mortality rates than younger @entity1 after @entity1187 ( @entity1187 ). However, the mechanism by which increasing age contributes to such mortality remains unclear. In addition, the efficacy and safety of invasive coronary procedures for octogenarians with @entity1187 have not been well established. We compared the clinical characteristics and in-hospital outcome of 193 octogenarians (mean age, 83 years) with those of 1,462 younger @entity1 (mean age, 64 years) with @entity1187 who underwent emergent coronary angiography. Octogenarians included a greater number of females, had higher rates of @entity66 , a higher Killip class, a higher Forrester class, and lower rates of smoking, @entity6 , and @entity1007 than the younger subjects. Interventions, including percutaneous transluminal coronary angioplasty (PTCA) and coronary artery bypass grafting (CABG), were performed less frequently in octogenarians than in younger @entity1 (88.0% versus 90.8%). The procedural success rate in octogenarians did not differ from that in younger @entity1 . However, the in-hospital mortality rate for the octogenarians was about three times higher than for the younger @entity1 (19.2% versus 6.9%). Multivariate analysis revealed that the predictors of in-hospital mortality in the octogenarians were a higher Killip class and a higher Forrester class. Octogenarians with @entity1187 had fewer coronary risk factors and a similar success rate for the intervention, but had more greatly impaired hemodynamics and higher in-hospital mortality than the younger @entity1 . Therefore, impaired myocardial reserve may contribute to a large portion of in-hospital deaths in octogenarians with @entity1187 .
