Spontaneous coronary artery dissection (SCAD) and takotsubo cardiomyopathy (TTS) are two non-atherosclerotic causes of myocardial infarction. They share several common features. Firstly, they have a predilection for the female gender and, in both, the exact mechanism has yet to be fully established. Both they could be responsible for an acute coronary syndrome. Hence, we want to do further consideration based on pathophysiology, literature review, and cases presented affected by both entities up today.
