ABSTRACT

BACKGROUND Elderly patients with both coronary heart disease (CHD) and diabetes mellitus (DM) undergoing off-pump coronary artery bypass grafting (CABG) face high risks of perioperative glucose fluctuations and impaired recovery. We evaluated the impact of a structured, multidisciplinary case management model on cardiac function and glycemic control in this population. MATERIAL AND METHODS This single-center, randomized controlled trial enrolled 168 elderly (≥65 years) patients with CHD and type 2 DM scheduled for off-pump CABG. Patients were randomized (1: 1) to a control group (CG, n=84; routine care) or an observation group (OG, n=84). The OG received routine care plus a 6-month multidisciplinary intervention including individualized cardiac rehabilitation, modified Mediterranean diet, psychological support, and intensified follow-up. The primary endpoint was 6-month left ventricular ejection fraction (LVEF); HbA1c was a key secondary endpoint. RESULTS All 168 randomized patients were analyzed. At 6 months, the observation group demonstrated significantly superior primary outcomes. LVEF was significantly higher in the OG (mean difference: 6.2%, P<0.001), and HbA1c was significantly lower (mean difference: 1.3%, P<0.001). The intervention group also showed significant improvements in secondary endpoints, including reduced left ventricular diameters (LVESD, LVEDD), an improved lipid profile (P<0.05), longer 6-minute walk test distance, and higher Diabetes-Specific Quality of Life (DSQL) and Activity of Daily Living (ADL) scores (P<0.0001). CONCLUSIONS Structured, multidisciplinary case management significantly improved cardiac function, metabolic control, and functional capacity in elderly diabetic patients after off-pump CABG, validating its efficacy for this high-risk group.
