Obesity Silently Damages Heart

specifically, this research work showed that people with obesity had raised levels of a heart enzyme known as troponin T, released by damaged heart muscle cells.
Overweight people without an obvious appearance of heart disease experience silent cardiac damage that speed up risk of heart failure in the future, with new research suggesting that obesity is an independent driver of heart muscle damage.
The findings challenge the commonly held belief that cardiovascular diseases seen in severely overweight people are driven by diabetes and high blood pressure, both well-known cardiac risk factors and both occurring frequently among the obese.
”Obesity is a well-known ‘accomplice’ in the development of heart disease, but our findings suggest it may be a solo player that drives heart failure independently of other risk factors that are often found among those with excess weight,”
Specifically, the research showed that obese people had elevated levels of a heart enzyme known as troponin T, released by injured heart muscle cells.
Increases in levels of this enzyme corresponded to an increase in people’s body mass index (BMI) – a measure of body fat based on a person’s weight-to-height ratio. Levels of the enzyme rose proportionally as BMI went up.
Troponin T is the gold standard for diagnosing acute or recent heart attacks and is widely used in emergency rooms to test patients with chest pain and other symptoms suggestive of a heart attack.
