The Claim

In adults with type 2 diabetes receiving thyroxine replacement therapy, impaired renal function (eGFR <45 mL/min/1.73 m²), hypertension, history of diabetic microvascular complications, end-stage renal disease, coronary heart disease, heart failure, cerebrovascular accident, and diabetic foot infection are associated with a higher incidence of major adverse cardiovascular events, while peripheral artery disease is not significantly associated with major adverse cardiovascular events.

In plain English

Among adults with type 2 diabetes on thyroxine therapy, conditions such as reduced kidney function, high blood pressure, diabetic eye or nerve damage, kidney failure, heart disease, heart failure, stroke, and foot infections are linked to a higher rate of serious heart-related events, while narrowing of the arteries in the limbs is not linked to these events.

See the scientific wording

In adults with type 2 diabetes receiving thyroxine replacement therapy, impaired renal function (eGFR <45 mL/min/1.73 m²), hypertension, history of diabetic microvascular complications, end-stage renal disease, coronary heart disease, heart failure, cerebrovascular accident, and diabetic foot infection are associated with a higher incidence of major adverse cardiovascular events, while peripheral artery disease is not significantly associated with these events.

Why this might work

Thyroid hormone makes blood vessels relax and reduces inflammation, which lowers blood pressure and slows artery damage. This helps prevent heart attacks, strokes, and other serious heart problems, especially in people with diabetes who already have damaged kidneys or blood vessels.

  1. Study: Risk factors and clinical implications of thyroxine replacement therapy on major adverse cardiovascular events in type 2 diabetes: a retrospective cohort study

    This study found that type 2 diabetes patients on thyroid hormone medicine who have kidney problems, high blood pressure, past heart attacks or strokes, or foot infections are more likely to have serious heart issues—but leg artery narrowing doesn’t seem to increase that risk in this group.
