Blood stem cell changes linked to heart and artery disease

PROJECT 4: Somatic evolution of the hematopoietic system in cardiovascular disease

NIH-funded research Massachusetts General Hospital · NIH-11269231

This project looks for tiny clonal changes in blood cells that may drive atherosclerotic heart and artery disease to help improve detection and future treatments.

What this research studies

This project will develop a very sensitive blood test using microsatellite sequencing combined with deep targeted sequencing to find small clonal expansions in the blood, including those without known cancer-linked mutations. Researchers will apply this test to samples from people with atherosclerotic cardiovascular disease to see which clonal patterns are associated with disease. They will compare clones that carry known leukemogenic driver mutations to those without such mutations to determine which are likely harmful. The goal is to clarify links between blood cell clones and cardiovascular disease to guide better risk prediction and targeted therapies.

Who could benefit from this research

Good fit: Ideal candidates are adults with atherosclerotic cardiovascular disease or related risk factors who can provide blood samples or join observational follow-up.

Not a fit: People without atherosclerotic cardiovascular disease, those unwilling to provide blood samples, or those seeking immediate treatment changes are unlikely to gain direct benefit from participation.

Why it matters

Potential benefit: If successful, the work could lead to blood tests that identify people at higher risk and new treatments that target harmful mutant blood cells.

How similar studies have performed: Earlier studies have linked clonal hematopoiesis to heart disease, but this project expands detection to mutation-free clones and thus explores a relatively new area.
