Levels of a lung protein found in the blood of smokers could indicate their risk of dangerous plaque build-up in blood vessels, according to a study published in journal Arteriosclerosis, Thrombosis, and Vascular Biology.
Researchers were able to determine the amount of circulating pulmonary surfactant B (SP-B), a protein which is found in damaged lung cells, in the study.
It was found that smokers who had higher levels of SP-B also had more build-up of dangerous plaque in the aorta.
“We now are close to having a blood test to help measure the smoking-related effects that contribute to atherosclerotic heart disease,” said Dr Anand Rohatgi, co-lead author of the study.
“Smoking is one of the biggest contributors to the development of heart disease.”
In other news, a study published in the American Journal of Cardiology has found that increasing the levels of high-density lipoproteins (HDL) cuts the risk of heart attack and stroke.
