[Cardiovascular hyperreactivity to physical stress predicts high blood pressure in working populations: 4 years follow-up].
BACKGROUND
High blood pressure (HBP) is a disease, and as well as a risk factor for other diseases, such as atherosclerosis. Cardiovascular hyperreactivity (CVHR) is a predictor for this disease. The aim of this study was to demonstrate if CVHR to physical stress predicts HBP in working populations.


METHODS
A four year (2008-2012) cohort study was conducted on two population groups: CVHR (48), and normal cardiovascular reactivity (40) after applying the Sustained Weight test. A survival analysis was used to predict HBP, and the χ(2) test and hazard ratio, with a confidence interval of 95%, were used for the statistical analysis.


CONCLUSIONS
The CVHR is a predictor of HBP, determined by the Sustained Weight test. The working populations can be stratified according to cardiovascular reactivity in order to introduce preventive health actions on the modifiable cardiovascular risk factors of future hypertensives in the workplace.
