ABSTRACT
AIM: This study aimed to evaluate the relationship between Timed Up and Go test performance and the incidence of older adult heart diseases and mortality.
METHODS: This was a retrospective cohort study of 1,084,875 older adults who participated in a national health screening program between 2009-2014 (all aged 66 years old). Participants free of myocardial infarction, congestive heart failure, and atrial fibrillation at baseline were included and were divided into Group 1 (<10 s), Group 2 (10-20 s) and Group 3 (≥20 s) using the Timed Up and Go test scores. The endpoints were incident myocardial infarction, congestive heart failure, atrial fibrillation, and all-cause mortality.
RESULTS: During mean follow-up of 3.6 years (maximum 8.0 years), 8885 myocardial infarctions, 10,617 congestive heart failures, 15,322 atrial fibrillations, and 22,189 deaths occurred. Compared with participants in Group 1, Group 2 and Group 3 participants had higher incidences of myocardial infarction (Group 3: adjusted hazard ratio = 1.40, 95% confidence interval = 1.11-1.77), congestive heart failure (Group 3: adjusted hazard ratio = 1.59, 95% confidence interval = 1.31-1.94) and total mortality (Group 3: adjusted hazard ratio=1.93, 95% confidence interval = 1.69-2.20). The additional risks remained after adjusting for multiple conventional risk factors. For atrial fibrillation, a linear trend of increased risk was observed with slower Timed Up and Go test speed, but was statistically marginal (Group 3: adjusted hazard ratio=1.17, 95% confidence interval=0.96-1.44).
CONCLUSION: Slower Timed Up and Go test speed is associated with increased risk of developing myocardial infarction, congestive heart failure, and mortality in older adults.
