Table 2 Microvascular parameters stratified by coronary artery disease group in each ethnic group presented as geometric mean (95% CI) after adjustment for age, mean arterial blood pressure, total cholesterol, HbA1 c and smoking history

From: Attenuation of microvascular function in those with cardiovascular disease is similar in patients of Indian Asian and European descent

  1. No known CAD (Coronary artery disease) recruited from general practice register with no documented history of, or medications suggested of coronary artery disease.
  2. Established CAD recruited with established symptomatic atherosclerotic coronary artery with at least one > 50% stenosis and evidence of other atherosclerotic disease on angiography
  3. p = significance between disease and control group and between each ethnic group; two-way analysis of variance (ANOVA), with test for interaction after adjustment (principle values log transformed)
