The Claim
Thyroid-stimulating hormone (TSH) and free T4 levels do not predict major adverse cardiovascular events in adults with type 2 diabetes receiving thyroxine replacement therapy, as no clinically useful cutoff values were identified through receiver operating characteristic analysis.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adults with type 2 diabetes who are taking thyroxine, the levels of TSH and free T4 in the blood do not reliably indicate whether a person will experience serious heart problems.
See the scientific wording
Thyroid-stimulating hormone (TSH) and free T4 levels are not predictive of major adverse cardiovascular events in adults with type 2 diabetes receiving thyroxine replacement therapy, as no clinically useful cutoff values were identified through receiver operating characteristic analysis.
Thyroid hormone increases nitric oxide in blood vessels, lowers bad cholesterol, and makes arteries more flexible, which protects the heart and blood vessels. These changes happen whether TSH or free T4 levels are high or low, so measuring those levels cannot tell who will have a heart attack or stroke.
What the research says
1 studyIn people with type 2 diabetes taking thyroid hormone, this study found that checking TSH or free T4 levels can't tell doctors who will have a heart attack or stroke — there's no magic number that predicts risk.
