Health experts have found that different blood pressure in separate arms are linked to risks of heart disease.

Cardiologist Oscar Garfein have said that 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.

“I found that in one arm, it was very, very low, and in the other one, it was normal. It helped me arrive at a diagnosis of a potentially-lethal condition,” said Garfein.

The new study shows that Garfein's way of taking blood pressure readings from both of his patients' arms could be more helpful in detecting heart disease or blood vessel problems.

The study showed that if two readings of systolic blood pressure are different by more than 15 then it might indicate narrowing of arteries to the legs, decreased blood flow to the brain, heart disease or a 70 percent increased risk of death from either heart attack or stroke.

The study said that if heart or blood vessel diseases are detected early then it could reduce death rates among patients.
