Correlation of Myocarial Oxygen Consumption Index with Hand Grip Strength and Sit to Stand in Coronary Artery Disease Patients Undergoing Angioplasty

Abstract

Introduction: The condition known as coronary artery disease (CAD) occurs when plaque deposits cause the arteries that carry blood to the heart to narrow or become clogged. PTCA is used to clear blocked coronary arteries and bring blood back to the heart muscle. It is crucial to understand how MVO2 correlates with hand grip strength and the sit-to-stand test in patients with CAD who have had angioplasty to improve patient outcomes.

Objectives: To find the correlation of MVO2 with HGS and Sit to stand test in CAD patients undergoing angioplasty.

Methodology: 50 subjects diagnosed with CAD were included in the study. MVO2, HGS, and STS were assessed pre and post angioplasty. MVO2 index was assessed using RPP, HGS    was assessed by handheld dynamometer, and lower limb strength was assessed by using 1 min STS. Data was analyzed by the software python version 3.9.

Result: There was no statistically significant correlation of MVO2 with HGS and STS pre  and post angioplasty.

Conclusion: From this study, we can conclude that there is a weak positive correlation of pre and post MVO2 with pre-post HGS and STS which is not statistically significant. After the comparison of pre and post data of MVO2, HGS, and STS; we can conclude that there was an  increase in strength and physical capacity of the subjects but it was not statistically significant.
