The Claim

Elevated arginine vasopressin (AVP) levels are associated with an increased risk of cardiovascular mortality and major adverse cardiac events, including heart failure, myocardial infarction, and stroke, through mechanisms involving AVP-mediated vasoconstriction, sodium retention, and endothelial dysfunction.

In plain English

Higher levels of the hormone arginine vasopressin are linked to a greater chance of dying from heart-related causes or experiencing serious heart events such as heart attack, heart failure, or stroke, due to its effects on blood vessel narrowing, salt retention, and blood vessel lining function.

See the scientific wording

Elevated AVP levels are associated with increased risk of cardiovascular mortality and major adverse cardiac events, including heart failure, myocardial infarction, and stroke, likely due to AVP-mediated vasoconstriction, sodium retention, and endothelial dysfunction.

Why this might work

When AVP levels rise, blood vessels tighten, the kidneys hold onto more salt and water, and the liver makes more sugar while fat storage increases. These changes raise blood pressure, overload the heart, damage blood vessel linings, and cause insulin resistance, which together increase the risk of heart attacks, strokes, and heart failure.

  1. Study: The Impact of Hydration on Metabolic Outcomes: From Arginine-Vasopressin Signaling to Clinical Implications

    This study shows that when your body has too much of a hormone called AVP—often because you're not drinking enough water—it can make your blood vessels tighten and your body hold onto too much salt, which stresses your heart and blood vessels over time. This helps explain why high AVP might lead to heart attacks or strokes.
