Correlation Hand Grip Strength and Walking Distance in Elderly

Coronary artery disease causes muscle dysfunction which leads to decreased muscle fitness due to reduced cardiac output, resulting in reduced oxygen uptake from the blood, and further decreases functional capacity or maximum oxygen uptake. The elderly population is an age group at risk of developing coronary artery disease. Handgrip strength s a good predictor for assessing overall muscle fitness, where handgrip strength assessment with a dynamometer is one method of determining muscle fitness, one of the factors affecting cardiorespiratory fitness, which can be assessed by the 6-minute walk test. This study wants to determine the correlation between handgrip strength and changes in 6-minute walk test after undergoing phase 2 cardiac rehabilitation in the elderly after coronary revascularization and this study also wants to know the predictive value using the parameters studied.
