A型行为对原发性高血压患者血浆儿茶酚胺的影响

Effect of type A behavior pattern on plasma concentration of catecholamines in patients with primary hypertension

本研究对１００例原发性高血压病人和１００例正常人进行Ａ型行为问卷的测试，并对原发性高血压组中测示为Ａ型行为，Ｂ型行为的各２０例患者及正常人群组２０例Ａ型行为者进行血浆儿茶酚胺的测定，结果显示：（１）正常人群组Ａ、Ｂ型行为的血浆儿茶酚胺（ＣＡ）水平在正常范围，两型间无差异；（２）原发性高血压组Ａ型行为者ＣＡ水平明显高于Ｂ型行为的ＣＡ水平；（３）高血压组Ａ型行为ＣＡ水平明显高于正常组的Ａ型行为的ＣＡ水平。由此提示：Ａ型行为可能对影响原发性高血压病的预后具有危险性。

One hundred patients with primary hyertension and 100 normal subjects completed Type A Behavior Pattern Questionnaire.Randomly selected 20 patients with type B behavior were received measurement of plasma concentration of catecholamines(CA) and compared with corresponding normal subjects of equal numbers.The results showed that:(1)No significant difference was found between type A behavior subjects and type B behavior subjects in normal control group;(2)In the patient group,thd plasma concentration of CA in typeA patients were obviously higher than that in type B ones;(3)Type A behavior patients were with significantly higher CA level than type A normal subjects.The authors speulated that type A behavior,mediated by abnormality in CA metabolism,is a high risk factor in further development of primary hypertension.
