Key result
Sustained handgrip in hypertensive patients elicited marked increases in blood pressure and moderate increases in heart rate and cardiac output, with higher mean arterial pressure than normotensives.
Why the study?
What are the haemodynamic responses to sustained handgrip in patients with hypertension compared to normotensive subjects?
Observational (n=15)
What are the haemodynamic responses to sustained handgrip in patients with hypertension compared to normotensive subjects?
Sustained handgrip in hypertensive patients elicits a similar haemodynamic response pattern to normotensives but results in higher absolute mean arterial blood pressures.

Similar handgrip responses in hypertension as in normotension; leaves open whether testing informs management, needing larger studies.
The haemodynamic responses to sustained handgrip were studied in 15 hypertensive patients. The response pattern was found to be similar to that in normotensive subjects, and was characterized by marked increase in systolic, diastolic and mean arterial pressure, moderate increase in heart rate and cardiac output, and no change in central venous pressure, stroke volume or total peripheral resistance. Mean arterial blood pressure was found to be higher in our patients than it is in normotensive subjects during static muscular contraction, and higher than it is in hypertensive subjects during dynamic exercise.

Hoel et al. (1970) conducted an observational in Hypertension (n=15). Sustained handgrip vs. Normotensive subjects was evaluated on Haemodynamic responses (blood pressure, heart rate, cardiac output, central venous pressure, stroke volume, total peripheral resistance). Sustained handgrip in hypertensive patients elicited marked increases in blood pressure and moderate increases in heart rate and cardiac output, with higher mean arterial pressure than normotensives.
