摘要
肾上腺素能活性增加,常表现为慢性心绞痛,可能对病程产生不利影响。鉴于可乐定(CL)对肾上腺素能神经系统的抑制作用,在一项双盲交叉研究中,对60例常规用药后每周至少出现5次冠状动脉疼痛的患者进行了小剂量CL治疗慢性心绞痛的有效性评估。CL以2 x 75微克/天的剂量口服,持续2周。53.7%的患者冠状动脉疼痛频率降低至少50%,硝酸甘油总消耗量从322片/周降低到174片/周,测功性能从168瓦×分钟/例增加到283瓦×分钟/例。尿中肾上腺素和去甲肾上腺素分泌减少。血压和心率没有明显变化。10例患者出现轻微和短暂性副作用,其中9例完成试验。结论:低剂量CL对慢性心绞痛患者是有效和安全的,可能是通过减轻肾上腺素能应激。
Clonidine effect in chronic angina pectoris. Double-blind, crossover trial on 60 patients.
Increased adrenergic activity, often manifested in chronic angina, is likely to influence adversely the course of the disease. In view of the inhibitory effect of clonidine (CL) upon the adrenergic nervous system, the effectiveness of small doses of CL in chronic angina was evaluated in a double-blind crossover study on 60 patients suffering at least 5 coronary pains per week in spite of routine medication. CL was given orally in a dose of 2 x 75 microgram/day for a 2 wk. Reduction in frequency of coronary pains by at least 50% was observed in 53.7% of patients, total nitroglycerin consumption decreased from 322 to 174 tablets/week, and ergometric performance increased from 168 to 283 W x min/patient. Urinary excretion of adrenaline and noradrenaline diminished. Blood pressure and heart rate were not considerably changed. Mild and transient side effects occurred in 10 patients, 9 of them completed the trial. It is concluded that CL in low doses is effective and safe in patients with chronic angina, presumably by alleviating adrenergic strain.
