在冠状动脉疾病患者,冷压试验使冠状动脉阻力增加和冠状动脉血流减少,可能是通过反射性冠状动脉痉挛。本文报道用冷加压试验(交感神经反射性兴奋)激发冠状动脉痉挛,以作为诊断冠状动脉痉挛的一种有用的非药物性方法。方法:35例胸痛综合征患者,男性34例,女性1例,平均年龄50.1岁(30～62岁),其中6例为变异性心绞痛(组1)。14例为典型性心绞痛(组2)。15例为无明确缺血性心电图表现的不典型胸痛(组3)。患者先作选择性冠状动脉造影,再进行冷加压试验。
In patients with coronary artery disease, cold compression tests increase coronary resistance and decrease coronary blood flow, possibly through reflex coronary artery spasms. This article reports the use of a cold compression test (sympathetic reflex excitation) to stimulate coronary artery spasm as a useful non-pharmacological approach for the diagnosis of coronary artery spasm. Methods: Thirty-five patients with chest pain syndrome, 34 males and 1 females, with an average age of 50.1 years (30-62 years), of whom 6 had variant angina (group 1). 14 cases of typical angina (group 2). Fifteen patients had atypical chest pain without definite ischemic electrocardiogram (group 3). Patients with selective coronary angiography before further cold compression test.
