Abstract
Background: Cardiovascular diseases (CVDs) remain a leading cause of mortality and morbidity globally, often associated with autonomic dysfunction. This dysfunction manifests as reduced heart rate variability (HRV), indicating imbalanced autonomic nervous system activity. Deep breathing (DB) techniques and yoga practices have been shown to enhance cardiovascular health by modulating autonomic function. Incentive spirometry (IS) is a widely used therapy in the management of postoperative and hospitalized patients with CVDs. This study aimed to evaluate the effects of IS combined with DB exercises on cardiovascular parameters in patients with coronary artery disease (CAD). Method: A quasi-experimental study design was employed, with 50 CAD patients divided equally into study and control groups. The study group received IS therapy along with DB exercises, while the control group received standard medical management. Various cardiovascular parameters, including heart rate, blood pressure, and electrocardiographic indicators, were measured pre- and post-intervention. Results: The results revealed significant improvements in cardiopulmonary parameters and electrocardiographic findings in the study group compared to the control group. Specifically, participants in the study group exhibited increased HRV, improved blood pressure control, and favorable changes in electrocardiographic indices indicative of enhanced cardiac function. Conclusion: In conclusion, the findings suggest that the combination of IS therapy with DB exercises may offer substantial benefits in managing CAD by improving autonomic function and cardiovascular health. Further research is warranted to elucidate the underlying mechanisms and optimize the implementation of these interventions in clinical practice.
Keywords: incentive spirometer, coronary artery disease (CAD), cardio-pulmonary parameters, ECG findings.
