Asian Indian Dylipidemia

Asian Indian Dyslipidemia 

  • The excess burden of CAD (coronary artery disease) among South Asians appears to be primarily due to dyslipidemia that is characterized by: high levels of apolipoprotein (apo) B, triglycerides (TG), lipoprotein(a), borderline high levels of LDL (low-density lipoprotein) cholesterol, low levels of HDL (high-density lipoprotein) cholesterol, and apo A1.1-3 Asian Indians have the lowest HDL and the highest ratio of total cholesterol to HDL and apo B to Apo A1─ the two best lipid predictors of heart disease as shown in Table 018.4-7
  • Nearly half of Asian Indians (but not Pakistanis or Bangladeshis) are lifelong vegetarians. Unlike in other populations, Asian Indian vegetarians and non-vegetarians have a nearly similar pattern of dyslipidemia and similar rates of CAD.3, 8, 9
  • Similar to diabetes and heart disease, dyslipidemia occurs at lower levels of BMI and body fat in South Asians than in Whites.10-12
  • An elevated level of total cholesterol is the strongest risk factor for CAD.13 The mean level of total cholesterol in cord blood of newborns worldwide is 75 mg/dL, which rises to 120 mg/dL in two weeks and remains at that level until approximately 20 years of age, when it starts to gradually rise again.14
  • Total cholesterol levels among Asian Indians are similar or lower than in Europids.3, 15 Long term prospective studies have shown an 8-fold higher CAD mortality with an increase in total cholesterol from <160 to >280 mg/dL among young Americans.16
  • The optimum level of total cholesterol appears to be <160 mg/dL,especially for Asian Indians, much lower than the 200 mg/dL considered desirable in the Western society.2 Contrary to common belief, very low levels of total cholesterol and LDL-C are not associated with increased risk of stroke or cancer.17-19 
  • Asian Indians around the globe have high triglycerides, and low HDL but LDL-C levels that are similar or lower than in the Europid population.4, 8, 20-30 This appears to be due to widespread insulin resistance even in the absence of obesity. 
  • Total cholesterol levels correlate well with the presence and severity of CAD in Asian Indians similar to whites.31, 32 At a given total cholesterol, Asian Indians have greater risk due to low HDL and high total cholesterol/HDL ratio.3, 15, 19
  • Asian Indians have a high prevalence of high triglycerides, which appears to be due to obesity and  high glycemic load  on aback ground of insulin resistance. 7 An 88 mg/dL increase in triglyceride levels significantly increases the risk of CAD by 30% in men and 75% in women.33-35
  • Despite high levels of TG, several studies fail to show a preponderance of small dense LDL among Asian Indians.7, 36-39
  • Among men and women, high TG/HDL-C ratio is a powerful independent predictor of small dense LDL, metabolic syndrome, myocardial infarction, cardiovascular events and all-cause mortality.40, 41
  • More than 40% of Asian Indians have high levels of Lipoprotein(a) which provides a genetic predisposition to premature CAD among Asian Indians. Elevated Lp(a) becomes particularly dangerous in the presence of low HDL and high total cholesterol/HDL ratio and account for the malignant heart disease in young Asian Indians.42
