title: Relationship of metabolic syndrome with quantum of coronary artery disease in Indian patients with chronic stable angina.
abstract: BACKGROUND
  The current study was aimed to ascertain presence and severity of coronary artery lesions in patients of Type 2 diabetic mellitus (DM) with coronary artery disease (CAD), in our population, by using scoring system analysis of the coronary angiography.
  
  
  METHODS
  147 consecutive patients with Type 2 DM of chronic stable angina (CSA) were enrolled in the study with 147 age- and sex-matched patients of CSA who did not have diabetes to serve as control. All of them underwent coronary angiography and were evaluated by using four scores to quantify the coronary artery lesions. The scores analyzed were coronary score, extent score, severity score, and atherosclerosis score. Other major risk factors such as smoking and hypertension lipid profile were also evaluated.
  
  
  RESULTS
  Type 2 diabetics with CAD had higher coronary score (0.91 +/- 0.63 in diabetics vs. 0.43 +/- 0.39, p < 0.001), extent score (4.91 +/- 3.1 vs. 2.3 +/- 1.8, p < 0.001), severity score (1.85 +/- 0.41 vs. 1.2 +/- 0.32, p < 0.001), and atherosclerosis score (0.52 +/- 0.31 vs. 0.21 +/- 0.26, p < 0.001) as compared to non-diabetics with CAD. Left main stem involvement, 2-vessel disease, and 3-vessel disease were also more frequent in the diabetics. These diabetes also had higher incidence of obesity, hypertension, and dyslipidemia.
  
  
  CONCLUSIONS
  In our population, diabetics suffer from higher prevalence of diffuse and extensive coronary atherosclerosis. The grades of stenosis in coronary arteries are also higher in diabetic patients when compared with non-diabetics with CAD, as was the prevalence of other components of the metabolic syndrome.
