Abstract:
Objective:This study explored the correlation between carotid intima-media thickness (CIMT) and cardiac diastolic dysfunction in patients with type 2 diabetes mellitus (T2DM).Methods:381 T2DM patients hospitalized in the endocrinology department of the Second Affiliated Hospital of Guangzhou Medical University from January 2019 to January 2020 were selected. According to E/A value, they were divided into normal diastolic function group (149 cases) and incomplete diastolic function group (232 cases); According to the CIMT value, they were divided into CIMT normal group (213 cases) and CIMT thickening group (168 cases). The general data, blood lipid, blood glucose, liver and kidney function, cardiac color Doppler ultrasound and carotid color Doppler ultrasound were compared and analyzed. Multivariate logistic analysis was used to analyze the influencing factors of cardiac diastolic dysfunction in patients with T2DM. Receiver operating characteristic curve (ROC) was used to analyze the ability of CIMT value to predict cardiac diastolic dysfunction in T2DM patients.Results:Multivariate regression analysis showed that age ( OR=1.067, P<0.001), increased CIMT ( OR=1.863, P=0.011) and systolic blood pressure ( OR=1.014, P=0.016) were the risk factors for occurrence of cardiac diastolic dysfunction in patients with T2DM ( P<0.05). ROC analysis demonstrated that the area under the curve (AUC) for cardiac diastolic dysfunction diagnosed by CIMT was 0.625 (95% CI: 0.568-0.683, P<0.001). The cut-off value was 0.875, with a sensitivity of 52.6% and specificity of 69.1%. Conclusions:Increased CIMT is an independent risk factor for cardiac diastolic dysfunction in patients with T2DM. The level of CIMT has certain predictive value for the occurrence of cardiac diastolic dysfunction.
