The Epidemiology of Heart Failure

The Epidemiology of Heart Failure

(p.9) Chapter 2 The Epidemiology of Heart Failure
Supportive Care in Heart Failure

This chapter concentrates on the state of knowledge in the epidemiology of heart failure (HF). It starts by addressing the definition, diagnosis, and cause of HF in order to understand the epidemiology of HF. It is stated by epidemiological studies that two-thirds or more of new cases of HF are diagnosed subsequent to a hospital admission. In addition, the problems with the interpretation of epidemiological studies are presented. It then emphasizes the epidemiology of clinical HF, left-ventricular systolic dysfunction (LVSD), heart failure with normal ejection fraction (HFNEF), and severe HF. The cause of HF is usually considered to be due to myocardial disease. However, many contributory factors conspire to exacerbate the underlying disease and some contributory factors may be a more important cause of HF than the underlying disease. It specifically discusses arrhythmias, anaemia, renal dysfunction, diabetes mellitus, liver disease, valve disease, dyssynchrony, and pulmonary hypertension, hypotension, and heart failure co-morbidities. In general, the epidemiology of HF is often over-simplified. Proper understanding, in absolute terms, of the numbers of patients and the type of HF that requires management should assist in the better planning of diagnosis and management.
