Relationship between sarcopenia and cardiovascular disease risk among Taiwanese older adults

Objective: Increasing evidence supports sarcopenia as an important parameter for predicting cardiometabolic risks. The objective of this study was to investigate the relationship between muscle mass, muscle strength, and physical performance, and cardiovascular risk among older community-dwelling adults. Design: The associations between dynapenia, sarcopenia, and Framingham risk score (FRS) were estimated by multivariate regression models. Setting: Muscle mass is estimated by skeletal muscle mass index using a bioelectrical impedance analysis. Muscle strength is measured by handgrip strength using an analogue isometric dynamometer. Physical performance is measured by gait speed using a 6-m walking distance. Dynapenia was defined as low muscle strength and/or slow gait speed presents with normal muscle mass. The diagnosis of presarcopenia and sarcopenia was based on criteria proposed by the Asian Working Group for Sarcopenia in 2014. The FRS was used for evaluating 10-year coronary heart disease (CHD) risk. Participants: Adults aged 65 years and older who attended health examinations from 2015 to 2017 were recruited. Results: There were totally 709 subjects enrolled in this study. Dynapenic men (n 47) had 17 center dot 70 +/- 5 center dot 08 % FRS and sarcopenic women (n 74) had 7 center dot 74 +/- 6 center dot 06 % FRS. Participants with presarcopenia had the lowest FRS (men: 15 center dot 41 +/- 5 center dot 35 %; women: 5 center dot 25 +/- 3 center dot 70 %). Men with dynapenia had higher FRS than the presarcopenia group with odds ratio (OR) of 2 center dot 52 (95 % confidence interval (CI): 1 center dot 03, 6 center dot 14). Women with sarcopenia had significantly higher FRS than the presarcopenia group with OR of 2 center dot 81 (95 % CI: 1 center dot 09, 7 center dot 27). Conclusion: Older dynapenic men and older sarcopenic women had higher risks of 10-year CHD. Presarcopenic older adults had the lowest CHD risk in both genders.
