New York, April 28 : Spending too much time sitting is bad for your heart as researchers, including one of Indian-origin, have found that sedentary behaviour is associated with increased amounts of calcium deposits in the heart’s arteries, which in turn is linked to a higher risk of heart attack.
“This is one of the first studies to show that sitting time is associated with early markers of atherosclerosis buildup in the heart,” said senior study author Amit Khera, associate professor at University of Texas Southwestern Medical Centre.
“We observed a significant association between increased sedentary time and coronary artery calcium,” Khera said.
“These associations were independent of exercise, traditional cardiovascular disease risk factors such as diabetes and high blood pressure, and socioeconomic factors,” Khera noted.
This research suggests that increased subclinical atherosclerosis characterized by calcium deposition is one of the mechanisms through which sedentary behavior increases cardiovascular risk and that this risk is distinct from the protective power of exercise,” he explained.
