Troponin T Reveals Damage
Obesity can lead to heart muscle damage and increased risk for heart failure even in the absence of overt heart disease, say researchers. The findings show that obesity can cause heart muscle injury independently of other risk factors like high cholesterol, high blood pressure and diabetes. Researchers at Johns Hopkins found the heart damage using an ultrasensitive blood test that shows measurements for the protein troponin T, which is released from damaged heart muscle cells. Researchers found that levels of troponin T rose as body mass index, or BMI, increased. The research is published in Journal of the American College of Cardiology: Heart Failure.
