Kim W, Park SH, Kim WS, et al. - Given the utility of quadriceps strength as a predictor of the level of exercise capacity in patients with coronary heart disease has been reported in a recent study, researchers explored if the link between muscular strength and exercise capacity is also noted with handgrip strength (HGS). Participants were 443 people (61.8 ± 11.2 yr; 78% male) who received coronary intervention and took part in cardiac rehabilitation between 2015 and 2018. Findings revealed the link of HGS with exercise capacity in coronary heart disease as well as supported its use as a predictor of the level of exercise capacity. An attainment of a 200-m walk on the 6-minute walk test was predicted by an HGS of 26% of body weight (positive predictive value = 0.95). The likely contribution of these observations was suggested in setting the recommended level of daily activity and the level of cardiac rehabilitation in coronary heart disease.
