Objective : To investigate the factors affecting concurrent sarcopenia among patients with cardiovascular diseases, so as to provide insights into early identification and prevention of cardiovascular diseases complicated with sarcopenia. Methods: A total of 250 inpatients with cardiovascular diseases in the Sixth Division Hospital of Xinjiang Production and Construction Corps were recruited and divided into the sarcopenia and non-sarcopenia groups according to the diagnostic criteria of sarcopenia. Subjects' basic characteristics, body mass index, blood biochemical indicators and human body composition parameters were collected using questionnaire surveys, and factors affecting concurrent sarcopenia among patients with cardiovascular diseases using a multivariable logistic regression model. Results: Among the 250 patients with cardiovascular diseases, there were 149 males (59.60%) and 101 females (40.40%). The overall prevalence of sarcopenia was 8.40% among the study subjects. The mean age and body mass index were (75.19±9.74) and (20.77±2.19) kg/m2 in the sarcopenia group and (65.24±11.50) years and (25.85±2.87) kg/m2 in the non-sarcopenia group. Multivariable logistic regression analysis identified age (OR=1.115, 95%CI: 1.030-1.207) and body mass index (OR=0.582, 95%CI: 0.445-0.761) were as factors affecting concurrent sarcopenia among patients with cardiovascular diseases. Conclusion Advanced age and low body mass index may increase the risk of concurrent sarcopenia among patients with cardiovascular diseases.
