Non-cardiovascular comorbidities in heart failure patients and their impact on prognosis.

With the aging of the population and improvement of life expectancy of patients with heart disease, there is an increase in non-cardiovascular (CV) comorbidities affecting chronic heart failure (HF) patients. The increased prevalence of different CV and non-CV comorbidities is a rising problem in the management of patients with HF, mostly because these comorbidities may lead to poor prognosis, increase of hospitalizations and mortality rate. Recently, important data from multicenter randomized studies point to diabetes mellitus or iron deficiency as new pharmacological targets, and this highlights the need of broad expertise for the 21st-century cardiologist. The management of HF should take into account non-CV comorbidities. In this review, we discuss novel aspects of non-CV comorbidities in HF patients and emphasize the impact on prognosis.
