Hypertensive response to exercise and exercise training in hypertension: odd couple no more

The diagnostic and prognostic implication of exaggerated blood pressure response to exercise has been controversial, with opinions ranging from a benign process to a harbinger of potential cardiovascular morbidity. Nonetheless, lowering of blood pressure and prevention of hypertension is in first instance preferable by lifestyle changes, and many studies have shown the inverse association between physical activity level and the incidence of cardiovascular diseases suggesting low aerobic fitness as a strong predictor for future cardiovascular disease and all-cause mortality in both healthy and cardiovascular disease patients, including those with hypertension.

Endothelial function, large artery stiffness and neurohormonal response are surely implicated both in the development of exaggerated blood pressure response to exercise and in the positive effect of physical exercise in the prevention and management of hypertension and cardiovascular disease in general.

In their interesting and well documented review published in this issue Kim and Ha broadly described the possible pathophysiologic mechanisms of exaggerated blood pressure response to exercise and its clinical implications: in this regard, a very interesting issue could be represented by the role of exercise training. In fact, there is an the ample evidence in the literature that physical activity could positively affect endothelial function, arterial stiffness, neurohormonal response and finally blood pressure levels both in healthy men and in hypertensive patients and so should be considered a very important element in the prevention and management of cardiovascular disease.
