[eng] Introduction: Both obesity and cardiovascular disease are highly prevalent worldwide and are responsible for high morbidity and mortality. The aim of this study is to assess the relationship between different scales that assess obesity and a scale that assesses cardiovascular risk such as heart age. Methods: Descriptive and cross-sectional study carried out in 139634 Spanish workers in which excess weight was determined by applying different scales, both anthropometric and based on the estimation of body and visceral fat, and cardiovascular risk was also assessed by applying the heart age scale. Results: The values of heart age are higher in those persons who present obesity applying any of the scales analyzed. The value of the obesity scales for predicting high values of heart age is scarce. Conclusions: There is a good relationship between the scales that assess excess weight and heart age values, but the value of these scales for predicting high values of heart age is not high.
