在以血流动力学监测、~(201)铊闪烁图和冠状动脉造影一系列的研究来证实冠状动脉痉挛的存在和它的起病方式时,可观察到在变异型心绞痛和常见的休息时心绞痛或不稳定型心绞痛之间有一种过度型的心绞痛。这种病人即使无变异型心绞痛的表现,但多数在缺血性发作之前并无使心肌需氧增加的血流动力学因素出现。曾观察到这种缺血性发作伴有心肌局部~(201)铊吸收的实际减少。我们也观察到在同一病人中有些心绞痛发作由冠状动脉痉挛引起,而另一些发作则由心肌需氧 In a series of studies with hemodynamic monitoring, ~ (201) Thallium scintigraphy and coronary angiography to confirm the presence of coronary artery spasm and its onset, it was observed that in variant angina and common rest Angina or unstable angina there is an excessive type of angina. Even though this patient had no evidence of variant angina, most had no hemodynamic factors that increased myocardial oxygen demand prior to the ischemic attack. It has been observed that this ischemic attack is accompanied by a real reduction of ~ (201) thallium absorption in the myocardium. We also observed some episodes of angina pectoris in the same patient caused by coronary artery spasms, while others were caused by myocardial aerobic
