A team of scientists in Britain’s University of Leicester has found out that the smaller your height, the greater risk you have of heart disease.
Scientist researched two million people to detect that part of DNA which controls the height and heart health.
The research results showed with the increase of every two and a half inches in height, the likelihood of heart disease is reduced to 13.5%.
The British Heart Foundation said the people of small stature should not be unnecessarily worried and because with a healthy lifestyle this risk can be reduced.
Heart disease in the UK, which includes heart attack and heart failure, is the leading cause of death. Each year, more than 73 thousand people have died beacued of heart problem.
50 years ago it was learned that the tall height has a key role in heart health, but researchers do not know why it had to be.
It also involve many other reasons, such malnutrition in childhood may impact on the height of a person that in turn affects heart.
But University of Leicester research shows that the answer is within our DNA.
They observed 180 genes were identified whose height was concerned.
‘I would not say that short heighted people should be more cautious because six feet one inch tall person needs to give up smoking as well’ ,says Nilesh Samani, a cardiologist at the University of Leicester in the U.K.
Samani and his colleagues looked at the genes of nearly 200,000 people, “and we found a very striking relationship,” Samani says.
For someone 2.5 inches shorter than average, the risk of coronary artery disease increases by about 13.5 percent. And the shorter you are, the larger the effect. But the risk is much smaller than the risk posed by smoking or high cholesterol.
The team didn’t see a significant connection in women. This could be because the study had fewer women — about 80,000, compared to men. Or there may not be a genetic effect of height on coronary heart disease in women.
“We’ve been rather simplistic in our view of what causes coronary artery disease,” Samani tells NPR. “We thought about traditional risk factors and then genes that might cause coronary disease. But what this [study] highlights for me is that probably developmental processes are going on that probably have an influence on height, and they probably also have an influence on [blood vessels of the heart] in a way that predisposes you to getting coronary artery disease.”
The challenge now is to ferret out the actual genetic variations that underlie both height and heart disease.
“Eventually, of course, there may be some treatments that could emerge from this, but I wouldn’t want to say that’s a short-term possibility,” Samani says.
