研究目的: |
在藏族中低危高血压患者中,比较三类一线降压药物,即肾素-血管紧张素-醛固酮系统抑制剂(renin-angiotensin-aldosterone inhibitor, RASI),钙离子通道阻滞剂(calcium channel blockers, CCB)和噻嗪型利尿剂的降压效果与安全性。 |
||
|
Objectives of Study: |
In Tibetan hypertensive patients at mild to moderate risk, to compare effects and safety of the following first-line antihypertensive drugs, i.e. renin-angiotensin-aldosterone system inhibitor (RASI), calcium channel blockers (CCB), and thiazide diuretics. |
||
|
药物成份或治疗方案详述: |
本研究将采用自身交叉对照研究的设计。未经治疗的藏族1级、2级血压水平的轻-中危高血压患者(18-79岁)将从四川省甘孜藏族自治州的数家医院中纳入。合格的研究对象将被随机分配到3*8周的治疗周期中,每个周期会以各自特定的顺序连续、先后给予受试者厄贝沙坦,氨氯地平,氢氯噻嗪治疗。观察主要指标为三种药物的血压下降水平,次要指标为血压达标率,安全性指标为不良事件发生率。预计需纳入531名患者,以80%的把握度,0.05的显著性水平,15%的失访率,检测两药之间5mmHg的收缩压下降值之差。 |
||
|
Description for medicine or protocol of treatment in detail: |
In a random crossover controlled manner, monotherapy effects of first-line antihypertensive medications will be compared, i.e. renin-angiotensin-aldosterone system inhibitor (RASI), calcium channel blockers (CCB), and thiazide diuretics. Untreated Tibetan hypertensive patients (aged 18-79 years) with BP≤180/110mmHg and cardiovascular risk within mild-moderate level will be recruited from Tibetan autonomous prefecture of Garz (Sichuan, China), and they will be randomized into three consecutively allocated 8-week treatment cycles with irbesartan, amlodipine and hydrochlorothiazide. The endpoints include the differences among three agents in BP reductions, BP control rates, and adverse events frequencies. A sample size of 531 (allowing 15% dropouts) will detect 5 mmHg systolic BP difference between any two drugs with 80% power. |
