ABSTRACT

Objective To discuss the clinical features and coronary artery lesions in middle-aged and young patients of coronary heart disease complicated with diabetes mellitus. Methods The clinical data of 386 middle-aged and young patients (aged from 28 to 59 years) of coronary heart disease were retrospectively analyzed. Among them, 176 cases were complicated with diabetes mellitus (diabetes group) and 210 cases didn′t have diabetes mellitus (non diabetes group). The general information, echocardiography and coronary angiography results between 2 groups were compared. Results The female ratio, incidences of hypertension and body mass index (BMI) in diabetes group were significantly higher than those in non diabetes group28.4%(50/176) vs. 6.7%(14/210), 63.6%(112/176) vs. 43.8%(92/210) and (26.5 ± 2.5) kg/m2 vs. (23.8 ± 1.7) kg/m2, and there were statistical differences (P0.05). The total cholesterol (TC) and triglyceride (TG) in diabetes group were significantly higher than those in non diabetes group(4.96 ± 1.32) mmol/L vs. (4.67 ± 1.12) mmol/L and (2.77 ± 2.01) mmol/L vs. (2.09 ± 1.60) mmol/L, the high-density lipoprotein cholesterol (HDL-C) was significantly lower than that in non diabetes group(0.92 ± 0.30) mmol/L vs. (1.10 ± 0.32) mmol/L, and there were statistical differences (P0.05). There were no significant differences in the left atrial diameter, right ventricular diameter, left ventricular end diastolic diameter, ejection fraction, aortic root inside diameter and incidence of weakened ventricular wall motion between 2 groups (P>0.05). The incidence of 3 branch coronary artery lesions in diabetes group was significantly higher than that in non diabetes group59.1%(104/176) vs. 37.6%(79/210), and there was statistical difference (P0.05). Conclusions In middle-aged and young patients of coronary heart disease complicated with diabetes mellitus, the female ratio is higher and hypertension, obesity and hyperlipidemia is more common. The lesions of coronary artery are more serious and diffuse. Three branch coronary artery lesions are the main ones, and the left main branch and the circumflex branch lesion is common.
