Hyderabad: Coronary artery disease (CAD) in Indians below 30 years is mainly due to inadequate consumption of fruits, vegetable salads and foods rich in folate and vitamin B 12 rather than mutations in certain genes.
A team of city researchers has found that a majority of young heart patients examined as part of the study consumed inadequate quantity of fruits and salads and foods fortified with vitamin B12 and folate or folic acid.
When their genetic makeup was studied to find out whether any mutation in genes was responsible for CAD, only a few patients showed such mutation. A majority of the young heart patients studied had no genetic mutations, and yet they got coronary artery disease mainly because of low intake of B12 and folate-rich foods, particularly vegetables and fruits.
The team comprised doctors from the Institute of Genetics and Hospital
for Genetic Diseases, Apollo Hospital, Care Hospital and Gandhi
Hospital. Coronary artery disease is linked to high levels of an amino
acid (homocysteine) and this is linked to mutations in genes known as
MTHFR and MS. But in 100 young heart patients examined, only a handful
had the mutation, while a majority of them had low levels of B12 and
folate. The quantum of homocysteine also goes up if dietary intake of
B12 and folate is insufficient. Smoking, intake of tobacco products
and lack of physical exercise added to the problem.
Young Indians are three times at higher risk of heart diseases than
people living in the West. "Though high levels of homocysteine have
been widely linked to the early onset of heart diseases in other
populations, a definite proof among Indians is lacking," the team
pointed out adding that high levels of this amino acid is linked
mainly to the diet rather than the genes.
The study gains significance as about 25 per cent of heart attacks
among men and women in India occur when they are younger than 40.
"This is unheard of in other populations," the researchers observed.
They said prolonged cooking and frying of vegetables results in loss
of 90 per cent of folate content.
