Abstract
Objective: To investigate the association between sarcopenia and ventricular remodelling after coronary artery bypass grafting (CABG) in elderly patients with coronary heart disease (CHD). Methods: A total of 135 elderly patients with CHD admitted to hospital between February 2021 and May 2023 were prospectively selected. According to whether ventricular remodelling occurred during the follow-up period, patients were divided into an occurrence group and a non-occurrence group. Results: The incidence of ventricular remodelling after CABG in elderly patients with CHD was 23.70% (32/135). Significant differences between the two groups were observed in smoking history, diabetes history, prevalence of sarcopenia, degree of preoperative coronary stenosis, levels of lipoprotein (a) ([Lp(a)]), uric acid (UA), protease-activated receptor 2 (PAR2), monocyte-to-HDL ratio (MHR), and suspended red blood cell input (P < 0.05). Multivariable logistic regression analysis identified smoking history (odds ratio [OR] = 2.186, 95% confidence interval [CI] 1.34–3.57), diabetes history (OR = 2.171, 95% CI 1.32–3.58), sarcopenia (OR = 2.230, 95% CI 1.37–3.62), a high degree of preoperative coronary stenosis (OR = 2.223, 95% CI 1.36–3.64), elevated Lp(a) (OR = 2.143, 95% CI 1.32–3.49), elevated UA (OR = 2.164, 95% CI 1.31–3.58), elevated PAR2 (OR = 2.192, 95% CI 1.32–3.64), and elevated MHR (OR = 2.201, 95% CI 1.32–3.68) as independent risk factors for ventricular remodelling after CABG in the study population. Analysis showed that sarcopenia predicted ventricular remodelling with a sensitivity of 90.0%, specificity of 47.0%, and an area under the curve of 0.772 (95% CI 0.68–0.86, P < 0.0001). Conclusion: Sarcopenia is a risk factor affecting ventricular remodelling after CABG in elderly patients and shows strong predictive efficacy in this population.
