Clonal Hematopoiesis and Cardiovascular Disease in Patients With Multiple Myeloma Undergoing Hematopoietic Cell Transplant
Main finding · CVDResult — go to the resultHazard ratio 2.72 95% CI 1.70–4.39Authors' conclusion
CHIP was significantly and independently associated with risk of CVD in patients with MM undergoing HCT and may serve as a novel biologically plausible biomarker for CVD in this cohort. Patients with MM and both CHIP and cardiovascular risk factors had an exceptionally high risk of CVD.

Cardiovascular disease (CVD) with CHIP plus preexisting hypertension or dyslipidemia
- CHIP + hypertension: nearly 7-fold increased risk; CHIP + dyslipidemia: 4-fold (reference: no CHIP, no hypertension, or dyslipidemia)
