Abstract P357: Ideal Cardiovascular Health Criteria are Inversely Related to Cardiovascular Disease and All-Cause Mortality in a Sample of Canadian Adults
Background: Ideal Cardiovascular (CV) Health is an AHA 2020 Impact Goal and consists of 7 health metrics which the public are encouraged to achieve. It is a relatively new definition of health so relationships with mortality need to be explored. The aim of this analysis is to investigate whether or not meeting higher numbers of Ideal CV metrics is related to CV disease and all-cause mortality in a sample of Canadian adults.
Methods: The sample included 6406 adults (18-74 y) from the Canadian Heart Health Surveys (1986-1995). Using Ideal CV Health definitions, data from an interviewer-administered questionnaire were used to classify ideal levels of the smoking, diet (sodium only) and physical activity metrics. BMI, cholesterol and blood pressure levels were classified using measurements assessed in clinic. Due to lack of fasting glucose data, responses on physician-diagnosed diabetes were used. Mortality linkage was conducted using the Canadian Mortality Database (1986-2004). Cox proportional hazard regression models were used to estimate relative risks of CV disease and all-cause mortality, controlling for age.
Results: There were 781 deaths (277 from CV disease) over 14.5 (range 0.5-16.0) years of follow-up. Overall, 0.4% and 2.9% of the sample had either 7 or 6 Ideal CV Health metrics and none of these individuals were classified as deceased from CV disease. Compared to those who had ≤ 1 of the metrics (n = 223), those with ≥ 5 metrics (n = 1012) had lower age-adjusted CV disease mortality risk (unadjusted hazard ratio: 0.20, 95% confidence interval [CI]: 0.11-0.39) and lower age-adjusted all-cause mortality risk (unadjusted hazard ratio: 0.32, 95% CI: 0.22-0.45). When stratified by sex, males with ≥ 5 metrics had an age-adjusted risk of 0.28 (95% CI: 0.13-0.63) of CV disease mortality and an age-adjusted risk of 0.33 (95% CI: 0.20-0.56) of death from all-cause mortality, compared to men with ≤ 1 metric. For females, those with ≥ 5 metrics had an age-adjusted risk of death from CV disease of 0.08 (95% CI: 0.02-0.39) and a risk of 0.36 (95% CI: 0.18-0.71) of death from all cause-mortality, compared to women with ≤ 1 metrics.
Conclusion: These data indicate that meeting 5 or more AHA Ideal CV Health metrics is related to lower all-cause and CV disease mortality. These Ideal CV Health metrics may be a useful health target in other countries.
