About this study

Official title: 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Postoperative mortality

    How does a heart failure diagnosis affect postoperative mortality at 30 days, 90 days, 180 days, and 365 days?

    Measured: 365 days

  2. Postoperative morbidity

    How does a heart failure diagnosis associated with postoperative morbidity at 30 days?

    Measured: 30 days postoperative

Secondary outcomes (1)
  1. Prevalence of heart failure

    What is prevalence of heart failure in surgery in Sweden?

    Measured: 5 years preoperative
