The structure of complications in patients with different musculoskeletal disorders after coronary artery bypass surgery

Th e aim of the research. To analyse the structure of complications in patients with coronary artery disease and different musculoskeletal disorders (MSD) undergoing elective coronary artery bypass graft surgery (CABG) with cardiopulmonary bypass. Material and methods. From 2019 to 2020, a single-centre cohort study was conducted on 387 stable coronary artery disease patients aged over 50 before elective CABG. The following MSD were assessed: sarcopenia, osteopenia, and osteosarcopenia. Patients were divided into four groups according to the MSD type: group I included 52 (13.4 %) patients with sarcopenia, group II included 28 (7.2 %) patients with osteopenia, group III was composed of 25 (6.5 %) patients with osteosarcopenia, and group IV included 282 (72.9 %) patients without MSD. Patients underwent CABG using cardiopulmonary bypass. Cardiovascular, infectious and non-infectious complications, death, a composite endpoint including cardiovascular complications and death, as well as the total number of complications were analysed. Results. Infectious complications were revealed in 23 (5.9 %) patients. Th e highest frequency of infectious complications was noted in patients with osteosarcopenia while the lowest frequency was found in patients without MSD (24 % vs 5.8 % in group I, 7.1 % in group II, 4.3 % in group IV). The highest number of surgical complications was noted in patients with sarcopenia and osteosarcopenia (17.3 % in group I, 7.1 % in group II, 12 % in group III, 5.3 % in group IV; p = 0.002). The composite endpoint was significantly more prevalent in patients with osteopenia (32.1 vs. 9.6 % in group I, 12 % in group III, and 12.8 % in group IV). Th ere were no statistically signifi cant diff erences in the total number of complications between the groups of patients with MSD. Th e complications were 2-fold more likely to occur in patients with osteopenia and osteosarcopenia compared to patients without MSD. Moreover, MSD increased the risk of the composite endpoint by 1.7 times (odds ratio (OR) 1.73, 95 % confi dence interval (CI) 1.04-2.89; p = 0.035); osteopenia increased the risk of the combined endpoint by 3 times (OR 3.01, 95 % CI 1.02-8.9; p = 0.046). Surgical complications were associated with baseline MSD (OR 1.71, 95 % CI 1.06-2.76; p = 0.026); sarcopenia increased the risk of surgical complications by 2 times (OR 2.02, 95 % CI 1.05-3.88; p = 0.034). Conclusion. The frequency of complications in patients with MSD was 1.79-fold higher compared with patients without MSD. Cardiovascular and infectious complications as well as complications associated with surgical treatment were more common in patients with MSD. MSD can be used as a risk factor for the development of in-hospital complications because the presence of these disorders increases the risk of cardiovascular complications, non-infectious complications and death by 1.7 times. Moreover, osteopenia was associated with a threefold increase in the composite endpoint risk, while sarcopenia doubled the risk of non-infectious complications.
