目的:报道1例冠状动脉发育不良(HCAD)合并小心综合征。方法:患者为73岁女性,因反复心绞痛入院。有10 a高血压病史,无糖尿病史。心脏超声示主动脉瓣增厚、钙化、关闭不全,左室舒张功能减低。X线胸片示心胸比值0.40。心电图无明显异常。结果:冠脉造影示右冠脉主干从后降支以远突然变细、变短,左冠前降支及回旋支变细,左室造影正常。经钙拮抗剂及阿司匹林等药物治疗后,症状缓解出院。结论:该患者为非常少见的存活下来的HCAD,同时合并小心综合征,这可能与心肌长期缺血致心脏发育不良有关。
Objective: To report a case of Coronary Artery Dysplasia (HCAD) with Caution Syndrome. Method: The patient was 73 years old and admitted to hospital for recurrent angina pectoris. Have a 10-year history of hypertension, no history of diabetes. Cardiac ultrasound showed aortic valve thickening, calcification, incomplete closure, reduced left ventricular diastolic function. X-ray showed heart ratio 0.40 chest. ECG no obvious abnormalities. Results: Coronary angiography showed that the right coronary artery suddenly became thinner and shorter from the descending branch, and the left anterior descending coronary artery and the circumflex artery became thinner and left ventricular angiography was normal. After calcium antagonists and aspirin and other drugs, relieve symptoms discharged. CONCLUSIONS: This patient is a very rare surviving HCAD with concurrent caution syndrome, which may be related to long-term myocardial ischemia caused by cardiac dysplasia.
