Abstract:
Objective: To investigate the impact of type 2 diabetes mellitus on progression and revascularization of coronary non-target lesions in patients with coronary heart disease. Methods: From January 2010 to September 2014, we retrospectively analyzed the clinical data of patients with coronary heart disease who underwent two consecutive coronary angiographies at Fuwai Hospital. At least one coronary non-target lesion was recorded at the first procedure in these patients. Patients were grouped according to the diagnose of type 2 diabetes mellitus. Demographic features, risk factors of coronary heart disease, laboratory results as well as characteristics of coronary non-target lesions were collected at baseline (first coronary angiography) and follow-up (second coronary angiography). Lesion progression was defined by quantitative coronary angiography analysis. Lesions revascularization was recorded. Multivariable Cox regression analysis was used to define the impacts of diabetes mellitus on progression and revascularization of non-target lesions. Subgroup analysis in diabetic and non-diabetic groups were further performed. Receiver operating characteristics curve was used to identify the predictive value of HbA1c. Results: A total of 1 255 patients were included, and 1 003(79.9%) were male, age was(58.0±9.7) years old. And 486 patients were diagnosed with type 2 diabetes mellitus. Follow-up time was (14.8±4.5) months. Compared with non-diabetic group, diabetic group were older with less male and had higher BMI index as well as higher prevalence of hypertension, dyslipidemia, prior myocardial infarction and prior percutaneous coronary intervention(all P<0.05). Diabetic patients also had higher level of white blood cells, erythrocyte sedimentation rate, C-reactive protein, endothelin and HbA1c at both baseline and follow-up compared with non-diabetic patients (all P<0.01). There was no significant difference on progression of non-target lesions (20.0%(97/486) vs. 18.5%(142/769), P=0.512), revascularization of non-target lesions (13.2%(64/486) vs. 15.9%(122/769), P=0.190) and non-target lesion related myocardial infarction(1.9%(9/486) vs. 1.3%(10/769), P=0.436) between diabetic and non-diabetic patients. Multivariable Cox regression analysis revealed that diabetes mellitus was not an independent predictor for progression and revascularization of non-target lesions (Both P>0.05). Subgroup analysis in diabetic patients showed that baseline HbA1c level(HR=1.160, 95%CI 1.009-1.333, P=0.037) was an independent predictor for non-target lesion progression. Cut-off value of HbA1c was 6.5% (Area Under Curve(AUC) 0.57, specificity 88.7%; sensitivity 24.2%, P=0.046) by receiver operating characteristics curve. Patients with HbA1c level above 6.5% had 2.8 times higher risk of lesion progression compared with patients with HbA1c level below 6.5% (HR=2.838, 95%CI 1.505-5.349, P=0.001). Compared with non-diabetic patients, diabetic patients with HbA1c below 6.5% also had lower risk of lesion progression (HR=0.469, 95%CI 0.252-0.872, P=0.012). ST-segment elevated myocardial infarction was an independent predictor for revascularization of non-target lesions in diabetic patients. Conclusion: Type 2 diabetes mellitus is not an independent predictor for progression and revascularization of coronary non-target lesions in patients with coronary heart disease. However, elevated HbA1c level is a risk factor for progression of non-target lesion in patients with type 2 diabetes mellitus.
