Abstract:
【Objective】Diabetes mellitus is a risk equivalent for coronary heart disease. This retrospective study was designed to investigate the risk factors of the progression of coronary lesions in patients with type 2 diabetes（T2DM）and Non- diabetes Mellitus（NDM）.【Methods】 526 patients with T2DM and 425 patients with NDM at the Third Affiliated Hospital of Sun Yat-sen University between March 2001 and January 2017 who underwent coronary imaging studies（coronary angiography or coronary CTA）twice during the same period were enrolled. The effects of cardiovascular risk factors on the progression of coronary lesions were analyzed in parallel in these two types of patients.【Results】Risk factors of the progression of coronary lesions in T2DM patients included smoking（OR = 1.836，95% CI：1.030~3.371，P = 0.04），Lp（a） ［OR = 1.001，95% CI：1.000~1.002，P = 0.004（baseline）；OR = 1.001，95% CI：1.000~1.002，P = 0.009（re-examined）］，HbA1c leve［l OR = 1.471，95% CI：1.030~2.100，P = 0.034（re-examined）］，uncontrolled LDL-C（OR = 1.882，95% CI：1.091~3.245，P = 0.023），TC［OR = 2.029，95% CI：1.028~4.008，P = 0.041（re-examined）］and low HDL-C ［OR = 0.017，95% CI：0.040~0.729，P = 0.017（re-examined）］. Comparative risk factors in NDM included BMI［OR =1.746，95%CI：2.462~2.712，P = 0.026（baseline）；OR = 0.001，95%CI：0~0.394，P = 0.025（re-examined）］，uncontrolled LDL-C（OR = 2.875，95%CI：1.669~4.952，P < 0.001）and low ApoA［OR = 0.282，95%CI：0.082~0.971，P = 0.045 （baseline）；OR = 0.117，95%CI：0.038~0.835，P = 0.029（re-examined）］. Lowest level of progression was found in the group with HbA1c<6.5%［0（0~3.4）points/year vs 0.3（0~3.0）points/year vs 1.0（0~5.1）points/year，P = 0.049. 0（-0.4~2.7）points/year vs 0.6（0~4.0）points/year vs 0.9（0~4.2）points/year，P=0.029］in T2DM patients.【Conclusion】Except for achievement of LDL- C goals，there might be some differences in risk factors for progression of coronary lesions between T2DM and NDM patients. Smoking，Lp（a），TC，HDL- C and control levels of HbA1c are independent predictors in T2DM as well as BMI and ApoA in NDM. Lowering HbA1c to less than 6.5% may delay progression of lesion.
