Heart failure (HF) is a growing disease that affects up to 6.5 million Americans and greatly contributes to the rising expense of health care. HF affects almost 23 million individuals worldwide. Exercise training increased patients' quality of life (QoL) and may be connected with lower morbidity and mortality. To assess the association between exercise training and QoL in HF patients. We examined databases from 2008 to 2019 for research that looked at the association between exercise training and QoL in HF patients. For the analysis, eight controlled studies that met the inclusion criteria were chosen. The study's characteristics, as well as data on QoL in HF patients, exercise training, and aerobic capacity, were extracted and examined. The investigation showed a more positive effect of the training exercise on patients' QoL after heart failure. Regular 30-minute exercise training three times a week for eight weeks is an effective strategy to improve all QoL aspects in individuals with chronic heart failure caused by various etiologies. These exercises had to be modified based on the patients' age and functional capacity.
