Our findings suggest CHIP remains relevant into later life & underscore its heterogeneity.

HRs for CHIP were comparable or greater than those for other conventional CVD risk factors (e.g., 👇)

In addition, we examined alternate thresholds of variant allele frequency to define CHIP; associations generally ⬇️ w/ smaller clone size

Key CHIP subtypes were associated w/ adverse CV events

Consistent w/ our prior work, TET2 CHIP associated w/ CHD & HFpEF

👀 ASXL1 CHIP ➡️ HFrEF (aHR >3)

Notably, no associations were seen when we lumped all CHIP types together, underscoring its heterogeneity

We therefore examined ~6,700 👵👵 from the Women's Health Initiative Long Life Study (median age 80 y) and sequenced blood cells ~4,500x in each participant to accurately detect 🔍 and quantify CHIP

Women were followed for ~10 y for coronary heart disease and several secondary outcomes

CHIP = aging-related acquired blood stem cell mutations that predispose to blood cancers

We + others have shown that CHIP also associates w/ ⬆️ CVD risk

But previous work suggested attenuation of associated risk in older adults, who have highest risk of both CHIP + CVD
