严重心绞痛,可由压低升高的收缩压、压低升高的心率和抑制收缩喷射时间延长等因素而降低痛阈,达到可耐受水平。如在许多很好的评论中所记载,这些因素与心肌氧气消毫(MVO_2)是一致的。心绞痛此种因素产物水平(“绞痛指数”),说明绞痛的发作各个痛阈。希望能预防诱发绞痛的身体和精神的因素,但常常难以实行,于遭受负荷前或后服用硝酸甘油,可使多年得到良好效果。持续的、自发的或迅速诱起的绞痛,尤其在疼痛类型改变时,无论称为前驱症状期或心肌梗阻期,都可能由于发生冠状动脉急性梗塞而引起。此类发作需要密切观察,适当地注意。精神压力较重的患者,可能反复表现这种疼痛,使诊断产生困难。对控制顽固的绞痛有各种不同的方式,许多方式前途大有希望,但是,当前最有效果的方法是:(1)
Severe angina pectoris can be reduced by lowering systolic blood pressure, lowering heart rate and inhibiting contraction injection time prolongation and other factors to reduce the pain threshold, reaching the tolerable level. As noted in many good reviews, these factors are consistent with myocardial oxygen consumption (MVO_2). Angina pectoris product level (“angina index”), indicating the onset of angina various pain threshold. The hope is to prevent the physical and mental factors that cause angina but are often difficult to administer and taking nitroglycerin either before or after suffering from a load may give good results for many years. Sustained, spontaneous or rapidly induced colic, especially when the type of pain changes, whether known as prodromal or myocardial infarction, may be due to the occurrence of acute coronary infarction caused. Such attacks need close observation, due attention. Patients with severe mental stress may repeatedly show this pain and make the diagnosis difficult. There are many different ways of controlling stubborn colic, and many are promising. However, the most effective ways to do this are: (1)
