Recently, a group of cardiologists from around the world began to wonder about troponins. Troponins are proteins produced by cardiac-muscle cells when they are hurt or dying. A heart attack releases a sudden tsunami of troponins into the bloodstream.
But even slightly elevated troponin levels, lower than those involved in heart attacks, are worrisome if they persist, most cardiologists believe. Chronically high troponin levels indicate that something is going wrong inside the heart muscle and that damage is occurring and accruing there. If the damage is not halted or slowed, it could eventually result in heart failure.
The researchers pulled information about more than 1,700 of these participants, excluding any who had heart disease or symptoms of heart failure, such as chest pain or shortness of breath.
They found, overall, sitting was more strongly associated with unhealthy troponin levels than exercise was with desirable amounts.
This is just an observational study and merely shows that sitting is linked to high troponins. It cannot explain why the rise in troponins nor injured cardiac cells when sitting.
We just have to sit less for now for health's sake.
