Coronary Artery Disease Incidence

  • Data for CAD (coronary artery disease) incidence in Asian Indians is sparse but was consistently and substantially higher than compatriots of other ethnic origins.1-3
  • The incidence rate of heart disease, in contrast to prevalence, is the number of new cases diagnosed each year or over a given period of time. It is usually the number of people getting heart attack per 100,000 per year.4
  • In the 10-year prospective follow-up of the St. James Survey in Trinidad, the age-standardized CAD incidence in Asian Indians was 2-fold higher than Whites and 7-fold higher than blacks.2
  • In Singapore, where all heart attacks in the country are systematically entered in the registry, the incidence of heart attack has been 3-fold higher among Asian Indians than Chinese men and women.1, 5-7
  • In many countries, hospitalization for heart attacks in Asian Indians compared to other ethnic groups is 2 to 4-fold higher overall and 5 to 10-fold higher in those under 40 years of age.8-10
  • The 18-year follow-up of the Whitehall-II study showed South Asians had higher cumulative incidence of angina (chest pain) than Whites and was accompanied by a worse prognosis than Europids.11
  • The 17-year follow up of a cohort in UK showed death rate from CAD among South Asians was 2.2-fold higher than whites even when adjusted for age, smoking, cholesterol, blood pressure, insulin resistance, abdominal obesity, metabolic syndrome, diabetes, and socioeconomic status.3
  • In the US, the hospitalization for CAD among Asian Indians was 3.6 times higher than whites and 6 times higher than Chinese.12
