Incidence of Heart Failure and Its Association With Postoperative Mortality in Surgery - a National Registry Study

The study is an exploratory study that aims to explore the incidence of heart failure in a national surgical cohort, and to compare postoperative mortality and morbidity in patients with and without heart failure. Furthermore, we want to investigate differences in the incidence of heart failure and its impact on postoperative morbidity and mortality in day surgery compared to inpatient surgery.
