The clinical management of CAD complicated by T2DM requires coordinated glycemic control, as poor management can exacerbate cardiovascular risks and increase morbidity and mortality. While endocrinologists traditionally manage diabetes, cardiologists are increasingly involved due to the cardiovascular risks associated with poor glycemic control. This study explores the current practices of glycemic management by cardiologists and endocrinologists in patients with CAD and T2DM, focusing on treatment intensification in a Chinese hospital setting.Methods: This cross-sectional study included 1,074 hospitalized patients with both CAD and T2DM, admitted to the Cardiology Department of Ruijin Hospital between January 2021 and December 2023. Data were retrospectively collected from electronic medical records, including demographic information, clinical characteristics, and treatment interventions. Patients were stratified by year, and differences in treatment strategies between cardiologists and endocrinologists were analyzed. Glycemic control was assessed using HbA1c levels, with treatment intensification defined by any adjustment in antidiabetic therapy and consideration for comprehensive cardiovascular risk factors.Results: Endocrinologists were significantly more likely to initiate treatment intensification, especially in cases of severe hyperglycemia (HbA1c ≥ 9.0%), while cardiologists’ role in glycemic management was limited, with a preference for outpatient endocrinology referrals over in-hospital adjustments. Despite improvements in glycemic control, the percentage of patients achieving comprehensive cardiovascular risk management targets remained low.Conclusion: This study underscored the distinct yet complementary roles of cardiologists and endocrinologists in managing glycemic control among patients with CAD and T2DM, noting endocrinologists’ more active involvement in treatment intensification. Future integrated care models should harness the unique expertise of both specialties to optimize patient outcomes, better address glycemic control needs, and enhance overall cardiovascular risk management in this high-risk patient population.Keywords: coronary artery disease, type 2 diabetes mellitus, glycemic control, cardiologists, endocrinologists, treatment intensification |
