The American Heart Association (AHA)'s National Goals are based on the novel term Ideal Cardiovascular Health, a measurable construct more positive than just the absence of clinical disease.
PURPOSE: We examined the effect of the simultaneous presence of 7 favorable health behaviors and factors on all-cause and cardiovascular disease (CVD) mortality in 11,240 adults (23.5% women) aged 20-82 years enrolled in the Aerobics Center Longitudinal Study from 1987 to 2003.
METHODS: All participants were free of CVD, cancer and abnormal electrocardiogram; had a body mass index (BMI) ≥18.5 kg/m2; and achieved ≥85% of age-predicted maximal heart rate on the treadmill test at baseline. Ideal Cardiovascular Health behaviors included not currently smoking, having a BMI=18.5-24.9 kg/m2, being physically active at or above 500 MET-minutes per week, and having a dietary pattern that includes at least two from a) ≥4.5 servings of fruit and vegetables per day, b) ≥ two 3.5-oz servings of fish per week; c) ≥ three 1-oz-equivalent servings of whole grains per day]. Ideal factors included serum total cholesterol <200 mg/dL, blood pressure <120/<80 mmHg, and fasting plasma glucose <100 mg/dL).
RESULTS: During 11.6 ± 3.5 years of follow-up there were 268 deaths, 60 from CVD. Compared to participants with Poor Cardiovascular Health (0 to 2 behaviors/factors), hazard ratios (HR) of all-cause mortality were 0.73 (0.56-0.97) for those with Intermediate Cardiovascular Health (3 to 5 behaviors/factors), and 0.79 (0.52-1.21) for those with Ideal Cardiovascular Health (≥6 behaviors/factors), after adjustment for age, sex and examination year. Adjusted HRs for CVD mortality were 0.40 (0.24-0.68) and 0.22 (0.06-0.74) for Intermediate and Ideal groups respectively. The inclusion of cardiorespiratory fitness (CRF) as a health factor (>20% of age- and sex-specific ACLS cohort) decreased the adjusted HRs of Intermediate and Ideal groups for both all-cause (0.46 (0.33-0.64), 0.49 (0.31-0.79)) and CVD mortality (0.29 (0.16-0.53), 0.14 (0.04-0.50).
CONCLUSION: AHA's definition of Ideal Cardiovascular Health presented a strong protective effect against CVD mortality. The diagnostic power of this tool can be improved by including CRF.
