Introduction:

Heart failure is a worldwide problem and will increase in the coming years as a result of population aging. It is associated with multiple comorbidities that may be involved in its development, contribute to the progression of the disease, or worsen the prognosis.

Objective:

To assess the influence of comorbidities on the mortality of patients with chronic heart failure.

Methods:

A retrospective cohort study was carried out in 242 patients with a diagnosis of chronic heart failure and a mean follow-up of 5 years in the heart failure protocol consultation at Hermanos Ameijeiras Surgical Clinical Hospital. The magnitude of the association between the presence of comorbidities and mortality was determined through the use of logistic regression.

Results:

The mean age was higher in deceased patients 72.12 ± 12.088 years (p = 0.003). The isolated presence of comorbidities did not show an association with mortality, but it did when more than two comorbidities coexisted. (OR: 2.91. CI: .991-8.61). A linear association was found between the number of comorbidities and mortality (p = 0.044).

Conclusion:

The studied comorbidities did not show an independent association with mortality, but the sum of them did increase the risk of death in patients with heart failure.
