A data compiled for last two years, part of one of the largest ongoing studies being conducted in 12 cities across India, has thrown up startling figures.

The study revealed that more than 70% of urban Indians are at a risk of developing heart disease during their lifetime. More than one lakh respondents were part of a web–based self–intervention survey over the Internet undertaken in a non–profit initiative by Marico Industries.

Heart age of individuals above 30 years was calculated using an algorithm based on "framing ham heart" study being conducted by US–based National Heart Lung and Blood Institute and Boston University.

Experts say that even as an individual might seemingly be young, the heart can age quicker than progression of biological years due to factors such as lifestyle, gender and levels of cholesterol or blood sugar in the body. Also, the frequency of eating fried and packaged food as opposed to whole grains and vegetables was also considered while surveying individuals.

Among these 70% people at risk, 64% fall between the age bracket of 30–34 years. Men are shown to be at a higher risk than women. Close to 75% men are at cardiovascular disease (CVD) risk, while only 66% women are likely to be affected by CVD. "Women in India seem to be doing better than men because of cardio protective cover hormone oestrogen which protects them from developing CVD at a young age, especially before menopause," observed the study.

Also, the study claims that one in six persons smoke, which doctors say is a precipitating factor for a deteriorating heart. "Smoking increases blood pressure and releases free radicals in the body responsible of a sinking heart," said Salome Benjamin, consultant nutritionist.
