1 Ten untreated hypertensive patients underwent 24 h continuous intra-arterial ambulatory monitoring of blood pressure (BP) and M-mode echocardiography. 2 They were treated with once-daily timolol and followed up at 2, 4, 8 and 12 weeks when dosage was titrated against BP control (indirect measurement) and degree of beta-adrenoceptor antagonism (submaximal bicycle ergometry and sub-lingual GTN). 3 Sixteen weeks after commencing therapy, nine patients underwent repeat continuous ambulatory monitoring of BP and M-mode echocardiography. 4 Casual BP was significantly reduced during the follow-up period at 2, 4, 8 and 12 weeks. 5 A reduction of BP was seen throughout the 24 h although this did not achieve statistical significance when sympathetic activity was low. 6 Echocardiographic measurement of left ventricular mass was significantly reduced after 16 weeks treatment.
10名未经治疗的高血压患者接受了24小时连续动脉动态血压监测和M型超声心动图检查。
他们接受每日一次的噻吗洛尔治疗,并在第2、4、8和12周进行随访,根据血压控制情况(间接测量)和β-肾上腺素能受体拮抗程度(次极量踏车运动试验和舌下含服硝酸甘油)调整剂量。
开始治疗16周后,9名患者再次接受连续动态血压监测和M型超声心动图检查。
在随访期间的第2、4、8和12周,偶测血压显著降低。
尽管在交感神经活动较低时24小时血压下降未达到统计学意义,但在整个24小时内血压均有下降。
治疗16周后,左心室质量的超声心动图测量值显著降低。
