Key result
An abnormal blood pressure response to exercise predicted the development of established hypertension at 2 years, occurring in 63.33% of exposed men versus 15% of those with a normal response.
Why the study?
Does an abnormal blood pressure response to exercise predict the development of established hypertension in men with borderline hypertension?
Cohort (n=28)
Does an abnormal blood pressure response to exercise predict the development of established hypertension in men with borderline hypertension?
An abnormal blood pressure response to maximal exercise testing is a strong predictor for the development of established hypertension in men with borderline hypertension.

May support risk stratification in borderline hypertension; leaves open whether exercise BP testing improves outcomes in prospective trials.
Twenty-eight men with borderline hypertension according to the World Health Organization criteria underwent maximal exercise testing, and then were followed for a two year period. The prevalence of abnormal blood pressure behavior during exercise was 53.58% (n = 15). During follow-up established hypertension developed in 63.33% (n = 10) of subjects with an abnormal blood pressure response to exercise, and only in 15% (n = 2) of subjects with normal blood pressure behavior. In predicting established hypertension development in a two year follow-up, maximal exercise testing has the following statistical values: sensitivity = 83.33%, specificity = 68.75%, accuracy = 75%, positive predictive value = 66.66%, negative predictive value = 84.61%.

Guerrera et al. (1991) conducted a cohort in Borderline hypertension (n=28). Abnormal blood pressure response to exercise vs. Normal blood pressure response to exercise was evaluated on Development of established hypertension. An abnormal blood pressure response to exercise predicted the development of established hypertension at 2 years, occurring in 63.33% of exposed men versus 15% of those with a normal response.
