Abstract/OtherAbstract:
This study investigated possible differences between hypertensive men and hypertensive women concerning the hemodynamic effects of incremental doses of exogenous epinephrine. The study population comprised 38 men (37 +/- 10 years) (standard deviation) and 25 women (33 +/- 9 years) with mild essential hypertension (mean blood pressure 147/90 and 147/93 mm Hg, respectively). Body mass index was slightly higher in men (25 +/- 3 kg/m2) than in women (23 +/- 2 kg/m2). Both groups received an intravenous infusion with epinephrine of 15 and 30 ng/kg/min for 8 minutes each. Despite the similar doses of epinephrine infused in both groups, the increase of venous plasma epinephrine in men was nearly twice that in women (1.04 +/- 0.09 vs 0.67 +/- 0.09 nmol/liter, p less than 0.01), suggesting that women cleared the infused epinephrine more efficiently than men. At the highest infusion dose, the increase of systolic blood pressure was larger in men than in women (5.3 +/- 1.2 vs 1.7 +/- 1.1 mm Hg, p less than 0.05). Conversely, the decrease of diastolic blood pressure was also larger in men than in women (-8.8 +/- 1.0 vs -5.8 +/- 1.0 mm Hg, p less than 0.05). The heart rate increased to the same extent in both groups (11.5 +/- 0.8 and 13.7 +/- 1.2 beats/min). If the blood pressure responses were corrected for the increase of plasma epinephrine, the difference between men and women disappeared.(ABSTRACT TRUNCATED AT 250 WORDS)
