The objective of the study is to evaluate the effectiveness of a self-care program that integrates physical exercise with components of aerobic and muscular strength training in improving functional capacity and muscular strength in people hospitalized for decompensated heart failure, in a clinical stabilization phase The main question it aims to answer is: Is the Self-care program that integrates physical exercise with aerobic and muscular strength training components effective in improving the capacity for self-care in people hospitalized for decompensated HF, in the clinical stabilization phase? In this randomized clinical trial, the Self-Care program will be applied in the experimental group. The ERIC-HF program will be applied in the control group. The ERIC-HF is a program of exercise only with an aerobic component. Participants will complete these programs during their hospital stay and various assessment instruments (quality of life, functional capacity, capacity for self-care, muscle strength) will be applied at admission, at discharge and one month after discharge.
