Acute hypercalcemic hypertension in man: Role of hemodynamics, catecholamines, and renin. The effect of acute hypercalcemia on blood pressure, blood volume, hemodynamic parameters, plasma norepinephrine, epinephrine, dopamine, renin, and aldosterone concentrations was investigated. After 1 hour of equilibration, 10 patients received an infusion of calcium gluconate in 5% dextrose (calcium 15 mg/kg of body wt in 3 hours). The calcium infusion increased the mean serum calcium from 8.7 to 13.0 mg/dl, the systolic blood pressure from 144 ± 10 to 184 ± (SEM) 12mm Hg (P < 0.001), the diastolic pressure from 78 ± 4 to 93 ± 5mm Hg (P < 0.01). The plasma volume was decreased by 9% (P < 0.001), whereas the hematocrit was increased (P < 0.05). Heart r...
