Risk Stratification of Cardiovascular Disease according to Age Groups in New Prevention Guidelines: A Review.

Abstract

Age is a strong risk factor for cardiovascular disease. Accordingly, most cardiovascular risk prediction models have included age as an independent risk factor. There is much evidence that effective management of cardiovascular risk factors improves clinical outcomes even in older adults. However, there are concerns that intensive treatment for older adults increases the risk of adverse events. For hypertensive patients, intensive blood pressure reduction with combination therapy increases the risk of syncope, acute kidney injury, and falls. Intensive glucose-lowering therapy among older patients with diabetes increases the risk of hypoglycemia or cognitive impairment. These findings suggest that a balanced approach for older adults is required to increase the benefits and decrease the risk of side effects. In contrast to older people, the estimated 10-year cardiovascular risk in young and healthy individuals is low. However, the lifetime cardiovascular risk in these patients is actually high. The 2021 European Society of Cardiology guideline on cardiovascular disease prevention in clinical practice has been published. It proposed a different risk stratification and recommendation for treatment according to age group, based on the concept of avoiding undertreatment in young people and overtreatment in older persons. Although the guideline recommends age-dependent risk stratification, risk categories should not be applied to the mandatory initiation of drug treatment. In all age groups, other factors such as lifetime cardiovascular risk, treatment benefit and harm, comorbidities, frailty, and patient preferences should be considered when managing patients for primary prevention.
