Survival analysis of patients with heart failure in the Ecuadorian Andean population

In western countries, it is estimated that one to two people per 100 adults have heart failure. In Latin America, and particularly in Ecuador, few studies have assessed survival in this disease. For this reason, this study aimed to determine survival and prognostic factors based on clinical and socio-demographic characteristics.

We did a single-center study of survival analysis in 228 patients with heart failure between 2015 and 2019. Survival analysis was done by the actuarial method and a multivariate Cox regression analysis.

Overall survival at the first year was 86% and at five years was 46%. Heart failure etiology (hazard ratio, 1.162: 95% confidence interval, 1.001 to 1.349; P = 0.049), ethnicity (1.415; 10.1 to 199; P = 0.043), age (1.035; 1.011 to 1.06; P = 0.04) and altered values of basal creatinine (1.21; 1.002 to 1.461; P = 0.048) were associated with worse prognosis.

Global survival time was similar to other international studies. Etiology, ethnicity, creatinine values, and age were factors associated with a worse vital prognosis.
