Nonagenarians admission and prognosis in a tertiary center intensive coronary care unit – a prospective study

Abstract Background With increasing life expectancy, the prevalence of nonagenarians with cardiovascular disease is steadily growing. However, this population is underrepresented in randomized trials and thus poorly defined, with little quality evidence to support and guide optimal management. The aim of the present study was to evaluate the clinical management, therapeutic approach, and outcomes of nonagenarians admitted to a tertiary care center intensive coronary care unit (ICCU). Methods We prospectively collected all patients admitted to a tertiary care center ICCU between July 2019 – July 2022 and compared nonagenarians to all other patients. The primary outcome was in-hospital mortality. Results A total of 3807 patients were included in the study. Of them 178 (4.7%) were nonagenarians and 93 (52%) females. Each year the prevalence of nonagenarians has increased from 4.0% to 2019, to 4.2% in 2020, 4.6% in 2021 and 5.3% in 2022. Admission causes differed between groups, including a lower rate of acute coronary syndromes (27% vs. 48.6%, p
