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.
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 (<0.001).
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.
癌症幸存者患心血管疾病的风险增加,这可能源于抗癌治疗对血管功能的负面影响。动脉僵硬度是血管功能的一个强有力指标,也是心血管疾病的独立预测因子。美国心脏协会建议通过实现“Life's essential 8”来促进心血管健康。然而,目前尚不清楚癌症幸存者对“Life's essential 8”的依从性更高是否与动脉僵硬度降低相关。
这项横断面研究纳入了 172 名年龄较大(≥65 岁)的癌症幸存者(74±6 岁;58%为女性)。根据 8 个组成部分:饮食、身体活动、尼古丁暴露、睡眠健康、体重指数、血脂、血糖和血压,计算出 Life's essential 8 的 100 分心血管健康评分,得分越高表明心血管健康状况越好。参与者的心血管健康状况分为低(<60 分)、中(60-79 分)或高(≥80 分)。脉搏波速度(PWV)用于评估动脉僵硬度;高动脉僵硬度定义为 PWV≥10m/s。平均心血管健康评分为 72±11,40 名(23%)幸存者存在高动脉僵硬度。与低心血管健康相比,高动脉僵硬度的优势比分别为 0.12(95%CI,0.03-0.50)和 0.02(95%CI,0.003-0.18),中、高心血管健康时的优势比分别为 0.12(95%CI,0.03-0.50)和 0.02(95%CI,0.003-0.18)。心血管健康评分每增加 10 分,脉搏波速度就会降低 0.43m/s(<0.001)。
癌症幸存者对美国心脏协会“Life's essential 8”的依从性越高,其动脉僵硬度高的发生率越低。需要进行具有更大样本量的前瞻性研究。
