Angina pectoris presenting with unusual form of coronary spasm: a case report]
Journal of cardiology(2006)
摘要
A 46-year-old male with asthma bronchiale and eosinophilia was admitted to our hospital because of continuous severe chest pain. Electrocardiography showed ST segment elevation in leads II, III and aVF during chest pain. Emergency coronary angiography showed a series of coronary arterial narrowings in segments 1 and 2. After injection of nitroglycerin 0.1 mg and nicorandil 2 mg into the right coronary artery, the coronary arterial narrowing was gradually relieved. The artery became completely normal after 10 min. Left coronary arterial angiography showed no abnormalities. The diagnosis was spontaneous coronary arterial spasm based on the coronary angiographic findings. The spasm occurred as multiple short narrow arterial segments. Normalization of the coronary artery took a long time. In a case like this, thrombus is easily formed that may cause acute myocardial infarction and unnecessary coronary angioplasty may be performed.
