Key result
Each additional ideal cardiovascular health metric was associated with a 31% lower risk of incident cardiovascular disease (HR 0.69) among Iranian adults.
Why the study?
The association between ideal cardiovascular health metrics and incident cardiovascular disease subtypes and all-cause mortality had not been quantified in an Iranian population.
Does meeting ideal cardiovascular health metrics reduce the risk of incident cardiovascular disease and all-cause mortality in an Iranian population?

Does meeting ideal cardiovascular health metrics reduce the risk of incident cardiovascular disease and all-cause mortality in an Iranian population?
Hazard Ratio: 0.69 (95% CI 0.65–0.73)
Meeting a higher number of ideal cardiovascular health metrics is strongly associated with a reduced risk of incident cardiovascular disease and all-cause mortality in an Iranian population.
Supports CV health metric promotion in Iranian adults; extends prior associations to this population.
Objective: To quantify the association between ideal cardiovascular health (CVH) metrics and incident cardiovascular disease (CVD) including different subtypes [coronary heart disease (CHD), stroke, and sudden death], and all-cause mortality in an Iranian population. Methods: The study population included 6,388 participants (2,726 men) aged 48.0 ± 12.4 years free of CVD at baseline. We utilized the American Heart Association's 2020 impact target criteria of ideal, intermediate, and poor CVH. The multivariate Cox proportional Hazard model, adjusted for age, sex, educational level, marital status, and family history of CVD, was applied to estimate the hazard ratio (HR) of outcomes per one additional metric of ideal CVH metrics. Furthermore, the risk was also calculated for ideal and intermediate categories considering poor category as a reference. Results: , and intermediate physical activity for all-cause mortality. Each additional metrics of ideal CVH decreased the risk by 31 (0.69, 0.65-0.73) for CVD, 32 (0.68, 0.64-0.73) for CHD, 31 (0.69, 0.60-0.80) for stroke, 25 (0.75, 0.64-0.88) for sudden death, and 13% (0.87, 0.81-0.93) for all-cause mortality events. Moreover, intermediate and ideal categories of CVH metrics were associated with lower risk for different CVD outcomes, i.e., 44 (0.56, 0.48-0.65) and 76% (0.24, 0.17-0.35) for CVD; 43 (0.57, 0.47-0.67) and 75% (0.25, 0.16-0.37) for CHD, 58 (0.42, 0.29-0.61) and 86% (0.14, 0.04-0.44) for stroke; 56 (0.44, 0.29-0.66) and 55% (0.45, 0.21-0.99) for sudden death; and 25 (0.75, 0.62-0.90) and 46% (0.54, 0.37-0.80) for all-cause mortality events, respectively. We also assessed the impact of changes in ideal CVH status from phase III to phase IV (2008-2011) on CVD events among 5,666 participants. Accordingly, compared to those remaining in the poor category, all of the changes in ideal CVH categories showed a lower risk for CVD events. Conclusion: Among the Iranian population, meeting higher ideal CVH metrics is associated with a lower risk of different CVD events and mortality outcomes.

Hadaegh et al. (2022) conducted a cohort in Cardiovascular disease prevention (n=6,388). Ideal cardiovascular health (CVH) metrics vs. Fewer ideal CVH metrics was evaluated on Incident cardiovascular disease (CVD) per additional ideal CVH metric (HR 0.69, 95% CI 0.65-0.73). Each additional ideal cardiovascular health metric was associated with a 31% lower risk of incident cardiovascular disease (HR 0.69) among Iranian adults.
