Abstract T P345: Cardiovascular Health Metrics and All-cause and Cardiovascular Disease Mortality among Middle Aged Men in Korea: The Seoul Male Cohort Study
Background: In Korea, Cerebrovascular and cardiovascular diseases (CVD) were the second leading cause of deaths in 2011. In 2010, the American Heart Association (AHA) published cardiovascular health metrics (CVHM) aimed at reducing deaths from all CVDs and stroke, and improving the cardiovascular health of the population as a whole. Despite their implications, the AHA’s metrics have not been broadly studied or previously applied to an Asian population.
Objectives: This study estimated the combined association of cardiovascular health behaviors on the risk of all-cause and CVD mortality in middle-aged men in Korea.
Methods: In total, 14,533 men aged 40-59 years were enrolled in 1993 and followed-up through 2011. CVHM defined the following lifestyles proposed by the AHA: smoking, physical activity, BMI, healthy diet score, total cholesterol, blood pressure, and fasting blood glucose. The CVHMs score was calculated as a single categorical variable, by assigning 1 point to each ideal healthy behavior vs. 0 points otherwise. All subjects were classified as meeting 0-7 CVHM. The principal outcome variables were all-cause and CVD mortality. The Cox proportional hazard regression model was used to estimate the hazard ratio (HR) of cardiovascular health behavior, and CVHMs score. PARs were calculated from significant CVHMs.
Results: During 266,482.8 person-years of follow-up, there were 1,314 deaths in total. Current smoking, blood pressure, and fasting blood glucose were significantly associated with all-cause and CVD mortality. The adjusted PARs for the 3 significant metrics combined were 81% (95% CI, 50-94%) and 96% (66-99%) for all-cause and CVD mortality, respectively. More ideal CVHM was significantly associated with lower risks of all-cause and CVD mortality (p-trend<.0001). The adjusted HRs of the groups with 6-7 vs. 0-2 ideal CVHM were 0.49 (0.35-0.70) and 0.23 (0.10-0.57) for all-cause and CVD mortality, respectively.
Conclusions: Among ideal cardiovascular health behaviors, non-smoking, normal blood pressure, and recommended fasting blood glucose levels associated with reduced risks of all-cause and total CVD mortality. There was a strong trend towards decreased all-cause and CVD mortality risk with increasing the number of ideal CVHMs.
