Outpatient coronary arteriography

A total of 12,719 outpatient coronary angiograms have been performed, using the Sones Technique, at Butterworth Hospital in Grand Rapids, Michigan, over the past 14 years. A consecutive series of 5,107 of these outpatient angiograms were selected for review here. Sixty-one percent of these patients were diagnosed with coronary artery disease. No deaths occurred in this series. Only 2.22% of patients in this series had complications. Outpatient coronary angiography is a safe, cost-effective, and efficient diagnostic technique.     

冠状动脉造影正常的冠状动脉疾病研究进展

有些冠状动脉疾病(如冠状动脉痉挛、心肌桥、冠脉微血管性心绞痛等)冠状动脉造影表现正常.有资料显示临床明确诊断为冠状动脉疾病的患者中有10%～30%冠状动脉造影正常.近年来随着血管内超声(IVUS)等新技术的飞速发展,对冠状动脉造影正常的冠状动脉疾病的研究有了更深入的进展.现就这一问题总结了几种冠状动脉造影正常的冠状动脉疾病,目的 是为正确的诊断和治疗这类疾病提供帮助.     

Exercise-induced coronary spasm with S-T segment depression and normal coronary arteriography

The unique association of both exercise-induced coronary arterial spasm and S-T segment depression with normal findings on selective coronary arterlography is described. The patient had a prior history of typical effort angina that had recently progressed to angina at rest. Despite the change In anginal pattern, the electrocardiogram disclosed S-T segment depression that was consistent with subendocardial Ischemia, during both exercise testing and spontaneous chest pain. Exercise thallium-201 sclntigraphy demonstrated the presence of large perfusion defects of the anterior and septal walls of the left ventricle. Coronary arteriographie findings, in the absence of symptoms, were entirely normal. Severe localized, reversible coronary spasm of the proximal left anterior descending coronary artery was subsequently demonstrated during spontaneous angina, Isometric arm exercise and after the administration of ergonovine maleate. After treatment with isosorblde dlnitrate and nifediplne, the patient had no further chest pain or electrocardiographic changes, and a repeated thallium-201 stress test revealed nomal findings and greatly Improved exercise tolerance.
