People with high thyroid hormone levels at heart disease risk

New Delhi: People with higher levels of thyroid hormones may be more likely to develop cardiovascular conditions such as heart attacks, strokes, say researchers.

Atherosclerosis -- hardening and narrowing of the arteries -- silently and slowly blocks arteries, putting blood flow at risk and thus increase the risk of heart diseases.

"Coronary heart disease and stroke remain a leading cause of mortality worldwide, despite advances in prevention and treatment. Therefore, identifying additional modifiable risk factors for atherosclerosis of major importance," said lead author Arjola Bano, doctoral student at Erasmus University in Netherlands.

The findings revealed that higher free thyroxine (FT4) levels -- hormones produced by the thyroid gland are primarily responsible for regulation of metabolism -- in patients elevated their risk of atherosclerotic morbidity and mortality.

"The study suggests that thyroid hormone measurement can help identify individuals at risk for atherosclerosis and may have future implications for the prevention of atherosclerotic morbidity and mortality," Bano added.

For the study, presented at the annual meeting ENDO 2017 in Orlando, US, the team included 9,231 people with an average age of 64.7 years.
