Abstract
Coronary vasospasm can lead to decreased cardiac perfusion and result in acute coronary syndrome. Here is a case of a 49-year-old man presented to the emergency department with epigastric pain and nausea with normal initial electrocardiogram. However, 6 h later, the patient experienced severe chest pain prompting a repeat electrocardiogram demonstrating inferior ST-segment elevation with troponin I levels peaked at 1.2 ng/ml (normal range: 0.00-0.02 ng/ml). Coronary angiography revealed angiographic stenosis in the left circumflex territory of a left dominant system which resolved with intracoronary nitroglycerin administration indicating ischemia with nonobstructive coronary arteries secondary to coronary vasospasm. He was discharged on isosorbide mononitrate and amlodipine therapy and had no recurrence of symptoms during follow-up.
期刊介绍：
Research advances have contributed to improved outcomes across all specialties, but the rate of advancement in cardiology has been exceptional. Concurrently, the population of patients with cardiac conditions continues to grow and greater public awareness has increased patients" expectations of new drugs and devices. Future Cardiology (ISSN 1479-6678) reflects this new era of cardiology and highlights the new molecular approach to advancing cardiovascular therapy. Coverage will also reflect the major technological advances in bioengineering in cardiology in terms of advanced and robust devices, miniaturization, imaging, system modeling and information management issues.
