The Claim

In hypertensive patients with fasting glucose levels ≤125 mg/dL, a higher triglyceride-glucose (TyG) index is associated with reduced endothelial progenitor cell counts and impaired microvascular function, regardless of the presence or absence of diabetes or coronary artery disease.

In plain English

In people with high blood pressure and normal fasting blood sugar, a higher triglyceride-glucose index is linked to lower levels of endothelial progenitor cells and worse microvascular function, whether or not they have diabetes or coronary artery disease.

See the scientific wording

In hypertensive patients with fasting glucose levels ≤125 mg/dL, the association between the triglyceride-glucose (TyG) index and reduced endothelial progenitor cells and impaired microvascular function is consistent across subgroups with and without diabetes or coronary artery disease, suggesting that metabolic dysfunction contributes to early vascular impairment regardless of overt cardiovascular disease status.

Why this might work

High levels of insulin resistance cause inflammation and stress in the bone marrow, which reduces the number of cells that repair blood vessels. With fewer of these repair cells in the bloodstream, the tiny blood vessels cannot respond properly to demand for blood flow, leading to reduced function.

  1. Study: Insulin Resistance is Associated With Skin Microvascular Dysfunction and Reduced Circulating Endothelial Progenitor Cells in Hypertensive Patients

    In people with high blood pressure and normal or slightly high blood sugar, higher insulin resistance (measured by fat and sugar levels in the blood) was linked to worse blood vessel repair and function—even in those without diabetes or heart disease. This suggests metabolic problems harm blood vessels early, before other diseases show up.
