Developing hypertension is likely to be at least two times greater in individual with exaggerated blood pressure response on exercise testing (ET). Few reports have evaluated the parameters of 24-hour Ambulatory Blood Pressure Monitoring (ABPM) in normotensive individuals with exaggerated blood pressure response to exercise.


To evaluate the relationship among the casual blood pressure with hyper-reactive response on ET and to compare Ambulatory Blood Pressure Monitoring (ABPM) data of hyper-reactive individuals with a control group in order to detect early disorders, that allows a preventive action with prognostic implication.


Casual BP measurement and parameters of ABPM of 26 adult individuals, with mean age of 41.50+/-11.78 years, normotensive at rest and hyper-reactive on ET was compared to those of 16 adult individuals, with mean age of 41.38+/-11.55 years, normotensive at rest with normal BP response on exercise. The values <140 x 90 mmHg were considered normal for casual BP. The values <220 mmHg for systolic BP and/or an increase > or = 5 mmHg diastolic BP on ET for hyper-reactive response diagnosis.


Hyper-reactive individuals presented the systolic (p=0.03) and diastolic (p=0.002) casual BP and mean systolic BP (p=0.050), systolic pressure load during the day (p=0.011), and systolic (p=0.017) pressure load higher when compared to the control group.


Casual high normal BP had a positive correlation with exaggerated BP response. The hyper-reactive individuals showed particular characteristics in casual BP as well as in ABPM parameters, which, although within the range of reference values, differed from those of individuals with normal response to exercise.
