Three large 2024 studies — a 50-million-person database analysis, a 29,000-patient cohort, and a landmark meta-analysis — found PDE5 inhibitor use associated with 22–30% reductions in cardiovascular events and mortality. Here is what the data actually says and what it means.
In 2024, three substantial datasets converged on a consistent finding: men who use tadalafil have meaningfully lower rates of heart attacks, cardiovascular events, and all-cause death than men who do not.
This is not a hypothesis. It is a pattern showing up in the largest population databases in medicine.
Understanding why requires understanding what tadalafil actually does to the vascular system — and why the endothelium is a better longevity target than most people realize.
Your endothelium is a single-cell-thick layer lining every blood vessel in your body. By surface area it is one of the largest organs you have — roughly 60,000 miles of vasculature covered by approximately 7 trillion cells.
When endothelial function is normal, all of this happens seamlessly. When it degrades — through oxidative stress, insulin resistance, hypertension, smoking, age — the downstream consequences reach every organ in the body.
