Abstract:
Objective To explore the incidence and clinical characteristics of sarcopenia in hospitalized elderly patients with coronary heart disease and search for the related factors. Methods This study was a single?center observational study. According to the inclusion criteria, elderly patients hospitalized with coronary heart disease from Peking Union Medical College Hospital between December 2017 and December 2018 were enrolled. The patients were divided into sarcopenic group and non?sarcopenic group according to the diagnostic criteria of the Asian Working Group for Sarcopenia. Activities of daily living of the patients were assessed (including ADL and IADL). Comorbidity of the patients was evaluated by the Charlson comorbidity index (CCI). Long?term medication use of the patients was recorded to assesse whether there was polypharmacy. The nutritional status of the patients was examined by the mini nutritional assessment?short form (MNA?SF). The full tandem stance time of the patients was evaluated. The history of falls over the previous year, urinary incontinence, and living conditions of the patients were also recorded. Multivariate logistic regression was used to analyze the related factors for sarcopenia of elderly patients with coronary heart disease. Results A total of 364 patients were enrolled in the study. The patients were aged 65-96 (74.6±6.5) years and there were 218 (59.9%) male patients. There were 264 cases of stable coronary heart disease and 100 cases of acute coronary syndrome. The median number of long?term used medication was 7. One hundred and fifty-two (41.8%) patients were complicated with type 2 diabetes, 38 (10.4%) patients were complicated with anxiety/depression, and 98 (26.9%) patients had the history of falls over the previous year. Eighty-two (22.5%) patients were complicated with urinary incontinence, 12 patients (3.3%) were complicated with malnutrition and 33 patients (9.2%) were living alone. There were 81 (22.3%) sarcopenic patients and 283 (77.7%) non?sarcopenic patients among all the hospitalized elderly patients with coronary heart disease. The sarcopenic patients were more older, with lower body mass index(BMI)(both P<0.001), higher CCI and more long?term used medication (both P<0.05), higher proportions of malnutrition, urinary incontinence, history of falls, and living alone (all P<0.05) compared to non?sarcopenic patients. ADL and IADL scores of sarcopenic patients were significantly lower than those of non?sarcopenic patients (both P<0.001). There was also a higher proportion of unable to accomplish full tandem stance among sarcopenic patients compared to non?sarcopenic patients (P<0.001). Moreover, higher hs?CRP level (P=0.047), lower albumin level (P=0.004) and significantly lower prealbumin level (P<0.001) were observed in sarcopenic patients compared to non?sarcopenic patients. Stepwise multivariate binomial logistic regression analysis revealed that male ( OR=5.036, 95%CI 1.782-14.230, P=0.002), low BMI ( OR=0.883, 95%CI 0.796-0.980, P=0.019), as well as low prealbumin level ( OR=0.990, 95%CI 0.980-1.000, P=0.045) were related factors for sarcopenia among elderly patients with coronary heart disease. Conclusions Sarcopenia is a geriatric condition commonly seen in hospitalized elderly patients with coronary heart disease. Male, low BMI, and low prealbumin level were the factors related to sarcopenia for older adults with coronary heart disease.
