A medical study indicates that ethnic Indians are far more susceptible to heart disease than other ethnic groups. The British study by Dr. Colin Bary, a consultant cardiologist from Manchestor, found that CHD (coronary heart disease) sets in earlier among Indians, than other nationalities. His study, which included Southeast Asians, Caucasians and South Africans said, Indians tended to experience CHD symptoms from the age of 50 onwards while it was in the 57-59 age group for other nationalities.
