Studies have shown people native to India, Pakistan, Bangladesh, Nepal and Sri Lanka can die from heart disease five to 10 years earlier than those from other ethnic groups.
Atherosclerosis in S. Asians is unlike the classical picture. It is diffuse in nature and doesn't just occur at the top of the arteries which is what is normally seen in other ethnic groups.
Reasons why:
- South Asians may have smaller than avg blood vessels in the heart. Therefore fat deposited on the blood vessel walls will shrink the available space for blood to flow.
- Abnormality in glucose and insulin signalling is seen much earlier in life in this segment of the population.
