In this brief presentation, Dr. Anne Truong MD cites research from major cardiovascular studies showing that clinically diagnosed erectile dysfunction (ED) consistently appears before overt heart disease, heart attacks, and peripheral artery disease by an average of three years—often ranging from two to five years before any chest pain or other cardiovascular symptoms emerge. She attributes this temporal relationship to the "artery size hypothesis": systemic risk factors such as high cholesterol, insulin resistance, and endothelial dysfunction cause arterial stiffening, and because penile arteries are smaller than coronary arteries, they become occluded earlier, making sexual dysfunction an early physiological signal. Dr. Truong frames sexual health as a practical "check‑engine light" for the heart, suggesting that clinicians should view new‑onset ED as a warning sign prompting cardiovascular risk assessment well before traditional symptoms arise.

Research data published across major cardiovascular studies show that true erectile dysfunction occurs before heart disease, before heart attack, before peripheral artery disease by an average of 3 years, often 2 to 5 years before any type of chest pain develops. Why did this happen? They call it the artery size hypothesis. When systemic inflammation starts, like high cholesterol, insulin resistance, and endothelial dysfunction happening that make the arteries stiff, where do you think the blood could start to flow first? Your sexual health is literally the check engine for your heart 3 years before that.
