根据传统的概念,不稳定性高血压者周围血管阻力正常,而持续性高血压者则增高。作者认为这种概念不完全正确,并研究了不稳定性高血压病人的总周围阻力和皮肤及肌肉血管阻力,与正常血压和持续性高血压者作了比较。研究对象包括正常血压者73例;原发性持续性高血压者173例;原发性不稳定性高血压者32例。后一组病史短,年龄小,血压波动于正常和异常之间,常伴有血管舒缩不稳定、潮热、多汗、手湿,血压波动常与精神—情感因素有关,内脏无受累的征象,心脏指数一般是高的,平均值为4.8±0.51(正常血压组及持续性高血压组的心脏指数平均值分别为3.44±0.92和3.28±0.62)。
According to the traditional concept, unstable peripheral vascular resistance in patients with hypertension is normal, while those with persistent hypertension are increased. The authors believe this concept is not entirely correct, and studied the overall peripheral resistance and skin and muscle vascular resistance in patients with unstable hypertension compared with normotensive and persistent hypertension. The subjects included 73 cases of normal blood pressure; 173 cases of primary persistent hypertension; 32 cases of essential hypertension. After a group of short history, age, fluctuations in blood pressure between normal and abnormal, often accompanied by vasomotor instability, hot flashes, hyperhidrosis, hand wet, blood pressure fluctuations are often associated with the spirit - emotional factors, visceral uninvolved Sign, cardiac index is generally high, with an average of 4.8 ± 0.51 (average heart index of normal and persistent hypertension were 3.44 ± 0.92 and 3.28 ± 0.62, respectively).
