Cardiovascular responses in borderline hypertension remain hypothesis-generating; leaves open prospective validation before informing risk stratification.
Observational (n=98)
Fahrenberg et al. (1993) conducted an observational in Blood pressure (borderline hypertensive, mildly elevated, normotensive) (n=98). Laboratory tasks (mental and physical) vs. Normotensive subjects was evaluated on Average daytime blood pressure and heart rate. Physical laboratory tasks like upright tilt and climbing stairs predicted average daytime blood pressure and heart rate better than psychological tasks in male students.
