Effects of calcium infusion on blood pressure in hypertensive and normotensive humans
- Hypertensive subjects exhibit enhanced Parathyroid Hormone gland function even when dietary factors are controlled, and they suggest that these subjects are more sensitive to the cardiovascular effects of short-term calcium infusion.
- In other words, it’s calcium deficiency, not sodium excess.
- During calcium infusion, systolic pressure increased in both groups, whereas diastolic pressure increased only when dietary sodium content was high and mean arterial pressure increased only in hypertensive subjects
- Hypertensive subjects exhibit enhanced Parathyroid Hormone gland function even when dietary factors are controlled, and they suggest that these subjects are more sensitive to the cardiovascular effects of short-term calcium infusion.
- PTH causes diuresis: loss of blood volume, dehydration, hypertension
- Activation of the renin-angiotensin system leads to hypertension.
