Myocardial Infarction With Nonobstructive Coronary Arteries (MINOCA)

Myocardial infarction with nonobstructive coronary arteries (MINOCA) is clinically defined by the presence of the universal acute myocardial infarction (AMI) criteria, absence of obstructive coronary artery disease (≥50% stenosis), and no overt cause for the clinical presentation at the time of angiography (eg, classic features for takotsubo cardiomyopathy).

With the more frequent contemporary use of coronary angiography in AMI, clinicians have been regularly confronted with this puzzling problem and seeking guidance in its management. An article by Lindahl et al in this issue of Circulation represents a major step forward in MINOCA and thereby warrants taking stock of the past, present, and future management strategies of this intriguing condition.

The ER ophthalmologist directed me to cardiology for a vascular problem.

A week later, I could not walk 100 meters (325 feet) without crushing chest pain and shortness of breath.

I was no longer functional. Making my bed was all I could do in a whole day. I was no longer an active 54-year-old.

Natsuko’s story

At 4am, I woke up in the dark with crushing chest pain, nausea, shortness of breath, and pain radiating to my left arm and jaw. I was terrified.
