Exercise and Cardiovascular Outcomes by Hypertensive Status: NHANES I Epidemiological Follow-up Study, 1971-1992

This study, consistent with previous observational data, demonstrates that increased exercise is associated with decreased CVD event. Interestingly, this effect is most robust among hypertensive subjects, whereas for prehypertensive and normotensive subjects, a significant benefit of exercise on CVD outcome, perhaps because of lack of power, was not found.
