Background Survivors of cancer have elevated risk of cardiovascular disease, likely stemming from the negative impact of anticancer therapies on vascular function. Arterial stiffness is a strong indicator of vascular function and independent predictor of cardiovascular disease. The American Heart Association recommends Life's Essential 8 for optimal cardiovascular health. It is currently unknown, however, whether greater adherence to Life's Essential 8 is associated with low arterial stiffness in survivors of cancer. Methods and Results This cross‐sectional study included 172 older adult (≥65 years) survivors of cancer (74±6 years; 58% female). Life's Essential 8 100‐point cardiovascular health score, with higher scores indicative of better cardiovascular health, was calculated based on 8 components: diet, physical activity, nicotine exposure, sleep health, body mass index, blood lipids, blood glucose, and blood pressure. Participants were classified as having low (<60), moderate (60–79), or high (≥80) cardiovascular health. Pulse wave velocity (PWV) was used to assess arterial stiffness; with high arterial stiffness defined as a pulse wave velocity ≥10 m/s. The mean cardiovascular health score was 72±11 and 40 survivors (23%) had high arterial stiffness. Compared with low cardiovascular health, the odds ratio of high arterial stiffness was 0.12 (95% CI, 0.03–0.50) and 0.02 (95% CI, 0.003–0.18) for moderate and high cardiovascular health, respectively. Every 10‐point increase in the cardiovascular health score was associated with a 0.43 m/s reduction in pulse wave velocity ( P <0.001). Conclusions Greater adherence to the American Heart Association's Life's Essential 8 was associated with lower prevalence of high arterial stiffness in older adult survivors of cancer. Prospective studies with larger samples are needed.
