Favorable cardiovascular risk profile in young women and long-term risk of cardiovascular and all-cause mortality

Area of Science:

• Cardiology
• Preventive Medicine
• Epidemiology

Background:

• Assessing the long-term impact of cardiovascular risk factors in young women is challenging due to low short-term mortality rates.
• Cardiovascular risk factors in young adulthood may have a significant influence on later-life health outcomes.

Purpose of the Study:

• To evaluate the association between baseline cardiovascular risk factor status and mortality from coronary heart disease (CHD), cardiovascular diseases (CVDs), and all causes in young women.
• To determine the risk associated with unfavorable cardiovascular profiles in women aged 18-39.

Main Methods:

• Prospective cohort study involving 7302 women aged 18-39 screened between 1967-1973.
• Risk groups were defined based on national guidelines for blood pressure, cholesterol, BMI, diabetes, and smoking status.
• Mortality outcomes (CHD, CVD, all-cause) were tracked over an average of 31 years, with hazard ratios calculated for different risk groups.

Main Results:

• Only 20% of women had a low-risk profile; 59% had one or more elevated risk factors.
• CVD death rates increased significantly with the number of risk factors.
• Low-risk women had a substantially lower risk of CVD mortality (HR=0.19) compared to those with multiple risk factors.

Conclusions:

• A favorable cardiovascular risk factor profile in young women is associated with rare occurrences of CHD and CVD.
• Maintaining a low-risk profile in young adulthood leads to significantly lower long-term and all-cause mortality.
• These findings underscore the importance of early cardiovascular risk factor management for women's long-term health.
