Chest Pain: Wellens Syndrome Due to Spontaneous Dissection of the Left Anterior Descending Coronary Artery - A Case Report and Literature Review
REVIEWS IN CARDIOVASCULAR MEDICINE(2024)
摘要
Wellens syndrome is an abnormal electrocardiographic pattern characterized by biphasic (type A) or deeply inverted (type B) T waves in leads V2-V3. It is typically caused by temporary obstruction of the left anterior descending (LAD) coronary artery due to the rupture of an atherosclerotic plaque leading to occlusion. Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome and even a rarer cause of Wellens Syndrome. It occurs when an intramural hematoma forms, leading to the separation of the tunica intima from the outer layers and creating a false lumen that protrudes into the real lumen, ultimately reducing blood flow and thus resulting in myocardial infarction. Here we report a case of SCAD presenting as an acute coronary syndrome with self-resolving chest pain, slightly elevated myocardial necrosis markers and electrocardiographic changes consistent with Wellens pattern type A first, and type B afterwards, that were not present upon arrival to the emergency department.
