Sitting for long hours in office? It could be dangerous. Doctors say, spending long hours on chair might lead to rise in coronary artery calcification that can increase the risk of a heart attack.
A research suggests that exercise may not entirely counteract the negative effects of a mostly sedentary lifestyle on coronary artery calcium. The study’s lead author Jacquelyn Kulinski says, that exercise is important to reduce your cardiovascular risk and improve your fitness level.
The study, however, suggests that reducing how much you sit every day may represent a more novel, companion strategy (in addition to exercise) to help reduce your cardiovascular risk.
Kulinski, an assistant professor of cardiovascular medicine at the Medical College of Wisconsin, US claims that the study offers a unique perspective on the effects of sedentary behaviour because it links sitting with an early marker for heart disease risk.
Coronary artery calcification, measured through a non-invasive CT heart scan, indicates the amount of calcium contained in plaques within the heart’s arteries.
The researcher came to the conclusion after analyzing heart scans and physical activity records of more than 2,000 adults living in Dallas. They found each hour of sedentary time per day on average was associated with a 14 percent increase in coronary artery calcification burden.
The association was independent of exercise activity and other traditional heart disease risk factors.
He further said, the study offers a promising message. Kulinski said, reducing the amount of time you sit by even an hour or two a day could have a significant and positive impact on your future cardiovascular health.
