Scientists have found a link between Y chromosome and risks of heart attacks in men in a new study that could help in the development of new treatments for men or help doctors find if patient is at a high risk of heart attack.

Scientists showed how the coronary heart disease (CHD) passes down the male line. They found that genetic variations on the Y chromosome increases the risk of siffering from a heart attack.

Dr Hélene Wilson, research advisor at the British Heart Foundation, said "This study shows that genetic variations on the Y chromosome - the piece of DNA that only men have - can greatly increase a man's risk of coronary heart disease. CHD is the cause of heart attacks, which claim the lives of around 50,000 UK men every year."

He said that lifestyle trends including poor diet and smoking are the major causes for the disease but inherence in DNA can also increase risks. A team of international scientists led by experts from the University of Leicester analyzed data from 3,200 men and found a variation on the Y chromosome could increase the risk of heart diseases by as much as 50 per cent.

In an earlier study, Health experts found that different blood pressure in separate arms are linked to risks of heart disease. Doctors usually check their patients' blood pressure incorrectly and this puts them at risks. It is found that doctors should take blood pressure readings from both of his patients' arms to find out risks of heart disease.
