The effect is critically reviewed of chronic administration of beta-adrenoreceptor antagonists on morbidity and mortality in angina pectoris and myocardial infarction. There is inconclusive evidence that the abrupt cessation of therapy with these agents may increase morbidity and mortality in angina pectoris. The type of anginal patient in which this may occur is not yet defined and neither is the mechanism. There is no evidence that beta-antagonists prolong the life of anginal patients. In the acute phase of experimental myocardial infarction, these drugs reduce mortality but do not do so in man. There is increasing evidence that they prolong life if administered to patients surviving the acute phase of myocardial infarction. The need for further studies is discussed.
对β-肾上腺素能受体拮抗剂长期给药对心绞痛和心肌梗死患者发病率和死亡率的影响进行了严格审查。尚无确凿证据表明突然停用这些药物会增加心绞痛患者的发病率和死亡率。可能出现这种情况的心绞痛患者类型尚未明确,其机制也不清楚。没有证据表明β受体拮抗剂能延长心绞痛患者的寿命。在实验性心肌梗死的急性期,这些药物可降低死亡率,但在人类患者中并非如此。越来越多的证据表明,对心肌梗死急性期存活的患者给药,这些药物可延长其寿命。文中讨论了进一步研究的必要性。
