RESUMO
Cardiovascular disease (CVD) and cancer are the two leading causes of morbidity and mortality in the world. The emerging field of cardio-oncology has revealed that these seemingly disparate disease processes are intertwined, owing to the cardiovascular sequelae of anticancer therapies, shared risk factors that predispose individuals to both cardiovascular disease and cancer, as well the possible potentiation of cancer growth by cardiac dysfunction. As a result, interest has increased in understanding the fundamental biological mechanisms that are central to the relationship between CVD and cancer. CVD and cancer frequently coincide in the same patient and often complicate each other. To date, much of the focus in cardio-oncology has been on the cardiovascular complications developed during cancer progression and as a result of cancer treatment. However, the reverse can also be true, and patients with CVD have been shown to be at increased risk of developing cancer (reverse cardio-oncology), as reviewed previously. Recently, the American Heart Association (AHA) updated the Life's Essential 8 (LE8) score, which captures modifiable risk factors, including smoking, body mass index, physical activity, sleep, dietary habits, blood pressure, fasting glucose, and total cholesterol levels, to assess CVH. Many studies have demonstrated a robust association between LE8 and CVD and all-cause mortality in the general population. Beyond assessment and monitoring, using metrics such as LE8 has the unique advantage to identify modifiable risk factors and refers cancer survivors for targeted interventions to manage their CVD risk. Future research in larger study samples is needed to investigate whether the optimal CVD defined by LE8 may differ in population subgroups and implement and evaluate CVD promotion interventions in the high-risk cancer survivor population.
