作者对于95名缓进型高血压病人,在入院即刻和住院2周以后,同时比较血浆去甲肾上腺素(PNA)的浓度、血浆肾素活性(PRA)和卧位血压值。PNA浓度按着青年(39岁以下)、中年(40～59岁)、老年(60岁以上)病人和肾素亚群组比较。1.在正常血压组年龄和PNA呈有意义的正相关(r=0.455,P<0.002),而在原发性高血压组并无此关系。2.在正常血压组进行年龄配对比较,年轻病人PNA显示有意义的高值(p<0.001),而在中年和老年病人无显著差异。3.观察到PNA和舒张压呈有意义的正相关(r=0.396,P<0.05)。并且在年轻病人和高肾素活性病人相关更加明显。
Authors of 95 patients with hypertensive type of hypertension, immediately after admission and 2 weeks after admission, while plasma norepinephrine (PNA) concentration, plasma renin activity (PRA) and supine blood pressure values. PNA concentrations were compared with those of the subgroup of patients (39 years of age or younger), middle-aged (40-59 years), elderly (60 years of age or older) and renin subgroups. 1. There was a positive correlation between age and PNA in the normotensive group (r = 0.455, P <0.002), but not in the essential hypertension group. 2. Age-matched comparisons in normotensives showed a statistically significant (p <0.001) PNA for younger patients but no significant difference between middle-aged and elderly patients. 3. A significant and positive correlation between PNA and diastolic blood pressure was observed (r = 0.396, P <0.05). And in younger patients and high renin activity of patients is more obvious.
