Correlation between body compositions and cardiopulmonary fitness in patients with coronary heart disease

Objective·To explore the correlation between body compositions and cardiovascular fitness (CRF) in patients with coronary heart disease (CHD).Methods·The CHD patients (CHD group) who underwent elective percutaneous coronary intervention treatment at Renji Hospital, Shanghai Jiao Tong University School of Medicine from October 2022 to June 2023 as well as healthy people (control group) were selected. All the participants completed cardiopulmonary exercise testing (CPET) to determine CRF and bioelectrical impedance analysis (BIA) to determine body compositions on the same day.Results·A total of 191 patients with coronary heart disease and 188 healthy individuals were included. There was no statistically significant difference in baseline characteristics between the two groups. Compared with the control group, the CRF indicators of the CHD group were significantly reduced (all P
