Study: Modifiable Risks Vary by Age in CVD Prediction
A study in Circulation has highlighted the varying impact of modifiable risk factors on cardiovascular disease risk across different age groups. The research suggests that multiple risk factors in younger individuals are more predictive of future cardiovascular events than the same factors in older adults.
The study found that age, sex, and race determine nearly three-quarters of cardiovascular disease risk. However, the impact of modifiable risk factors such as smoking, high blood pressure, high blood lipids, diabetes, metabolic syndrome, obesity, and sedentary lifestyle decreases with age. High systolic blood pressure (SBP) and high LDL cholesterol are prevalent and significant risk factors, even in older adults. Maintaining a heart-healthy diet, controlling weight, managing blood pressure, optimizing blood sugar, and keeping cholesterol levels normal can help lower cardiovascular disease risk. The study also noted that lowering SBP to normal and LDL cholesterol by 30% could substantially reduce heart attacks.
The findings emphasize the importance of considering age when assessing cardiovascular disease risk. While modifiable risk factors are crucial, their predictive value decreases with age. Therefore, healthcare providers should consider the unique risk profile of each patient, including age, when developing prevention strategies.
