Abstract

BACKGROUND: Lifetime risk is an informative estimate for driving lifestyle and behavioral changes especially for young adults. The impact of composite risk factors for cardiovascular disease on lifetime risk stratified by sex has not been investigated in the Japanese population, which has a much lower mortality of coronary heart disease compared with the Western population. We aimed to estimate lifetime risk of death from cardiovascular disease attributable to traditional risk factors. METHODS AND RESULTS: We analyzed pooled individual data from the Evidence for Cardiovascular Prevention from Observational Cohorts in a Japanese cohort study. A modified Kaplan– Meier approach was used to estimate the remaining lifetime risk of cardiovascular death. In total, 41 002 Japanese men and women with 537 126 person-years of follow-up were included. The lifetime risk at the index-age of 45 years for those with optimal risk factors (total cholesterol <4.65 mmol/L, systolic blood pressure <120 mm Hg, diastolic blood pressure <80 mm Hg, absence of diabetes, and absence of smoking habit) was lower compared with the highest risk profile of ≥2 risk factors (6.8% [95% CI, 0%–11.9%] versus 19.4% [16.7%– 21.4%] for men and 6.9% [1.2%–11.5%] versus 15.4% [12.6%–18.1%] for women). CONCLUSIONS: The magnitude and the number of risk factors were progressively associated with increased lifetime risk even in individuals in early adulthood who tend to have low short-term risk. The degree of established cardiovascular risk factors can be converted into lifetime risk. Our findings may be useful for risk communication in the early detection of future cardiovascular disease risk.
