Impact of Walking and Respiratory Training on Cardiopulmonary Function and Activity Endurance in Patients With Chronic Heart Failure.

OBJECTIVE

This study aimed to examine the impact of combining walking with respiratory training in patients with chronic heart failure (CHF).

METHODS

Eighty patients with CHF, admitted to the Department of Cardiology at the Affiliated Taizhou People's Hospital of Nanjing Medical University between January 2024 and June 2024, were selected as study participants. They were randomly assigned to either a control group or an observation group, with 40 patients in each group. The control group received standard rehabilitation care, while the observation group underwent walking combined with respiratory training along with standard rehabilitation care. Cardiac function, pulmonary function, and activity tolerance were compared between the two groups.

RESULTS

After 3 months of intervention, the observation group exhibited lower levels of heart rate (HR), left ventricular end-diastolic diameter (LVEDD), and left ventricular end-systolic diameter (LVESD) compared to the control group, while the left ventricular ejection fraction (LVEF) was significantly higher (p < 0.05). Additionally, the forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), FEV1/FVC ratio, and 6-min walking distance were greater in the observation group compared to the control group (p < 0.05).

CONCLUSION

In patients with CHF, combining walking and respiratory training significantly enhances cardiopulmonary function and activity tolerance, demonstrating potential clinical use.
