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.

Contemporary Diagnosis and Management of Patients With Myocardial Infarction in...

Myocardial infarction in the absence of obstructive coronary artery disease is found in ≈5% to 6% of all patients with acute infarction who are referred for coronary angiography. There are a variety of causes that can result in this clinical condition.

As such, it is important that patients are appropriately diagnosed and an evaluation to uncover the correct cause is performed so that, when possible, specific therapies to treat the underlying cause can be prescribed.

Real Patient Stories

Lynn’s story

I had my first spasm when I was just a young child and continued for almost 50 years with no diagnosis. I always assumed everybody had flushing feelings throughout their body, and hot flashes accompanied by chest pain.

It wasn’t until I was walking my dogs with my sister, one day, and we were going up a steep incline and I couldn’t keep up. I asked her if she felt chest pains when she walked up hills. She looked at me like I was crazy and told me: No!

I then realized something might be wrong with me.

Dima’s story

March 3rd, 2021 was the day that changed everything. At 55, I had a busy counselling practice and a few other projects on the go. The pandemic was causing anxiety for many of my clients and in my private life. I had a lot of stress of my own: there were safety issues in the building where I lived, and I was looking for a new apartment. Despite this, I thought I was handling it well. I was fairly healthy, I walked daily, ate well, meditated and didn’t smoke or drink.

I started to experience heavy fatigue towards the end of 2020 but told myself it was normal considering all that was going on in the world.

MaryAnn’s story

When I was 39, with zero risk factors for heart disease, I had all the classic symptoms associated with a heart attack. My doctors put me on three blood thinners to dissolve a clot in a minor artery seen in an angiogram. The next day, while the original clot had dissolved, I had a clot in a larger artery. Baffled, the cardiologists put in a stent. As they backed the scope out of the artery, it spasmed in another location.

At that time, I had a 4-year-old, an 8-year-old, and a 12-year-old. My husband traveled extensively for work. I asked myself two questions: 1) How do I feel about dying at age 39? 2) If I don’t die, how do I live?
