Changing clinical profiles and in-hospital outcomes of octogenarians undergoing cardiac surgery over 18 years: a single-centre experience

Abstract OBJECTIVES With an ageing population, increasing numbers of octogenarians are undergoing high-risk cardiac surgery. We examine the changing characteristics and in-hospital outcomes for octogenarians over an 18-year period. METHODS Clinical data from our prospective database for all octogenarians who had cardiac surgery from March 1999 through May 2016 were reviewed. We examined trends, risk profiles and in-hospital outcomes over 3 eras, namely early (1999–2004), middle (2005–2010) and late (2011–2016). A multivariable analysis was performed to identify independent predictors for adverse outcomes. RESULTS There were 1022 patients aged 80–94 years in our study cohort. The octogenarian population increased progressively from early to late eras (4.5%, n = 255 vs 7.1%, n = 321 vs 9.3%, n = 446), as the average logistic EuroSCORE predicted mortality (9% vs 9.7% vs 10.1%, P
