coronary microvascular dysfunction:
summary:
. if you feel like a heart attack is happening
but they can't find an obstructed or clogged artery,
that is known as MINOCA:
myocardial infarction [heart cell death due to blood loss]
with non-obstructive coronary arteries
which can be caused by artery spasms, ripped artery,
or a new condition that is known by many names:
coronary microvascular dysfunction
Coronary microvascular disease
Microvascular endothelial dysfunction
Cardiac syndrome X
Nonobstructive coronary heart disease.

The Association of Medical Illustrators is
excited to announce the launch of
the first round of illustrations through the
AMI Diversity Fellowship,
made possible by a grant through Johnson & Johnson’s (J&J)
Our Race to Health Equity (ORTHE) initiative.
In recognition, we will be highlighting the work of
each of our Diversity Fellows.
eg, the first illustration highlights
myocardial infarction with non-obstructive coronary arteries.

(MINOCA), can be caused by artery spasms
or coronary microvascular dysfunction.
interesting that mentions
"coronary microvascular dysfunction";
it is a new diagnosis with many names...
Small vessel disease
https://www.mayoclinic.org/diseases-conditions/small-vessel-disease/symptoms-causes/syc-20352117
Small vessel disease may also be called:
Coronary microvascular disease
Microvascular endothelial dysfunction
Small vessel disease is treatable but may be difficult to detect.
The condition is typically diagnosed after finding
little or no narrowing in the main arteries of the heart
despite the presence of symptoms that suggest heart disease.
Coronary Microvascular Disease (MVD)
In coronary MVD, the heart's coronary artery blood vessels
don't have plaque, but damage to the inner walls of the blood vessels
can lead to spasms
or abnormalities in smaller arteries.
Other names for coronary microvascular disease:
Cardiac syndrome X
Nonobstructive coronary heart disease
Treatment
Medications to relax blood vessels including
beta blockers, calcium channel blockers and nitroglycerin.

What is MINOCA? A Type of Heart Attack Mostly Affecting Women
. myocardial infarction with non-obstructive coronary arteries
(MINOCA), is garnering increased attention.
Janet Wei, MD, and Noel Bairey Merz, MD:
MINOCA is a heart attack caused by
poor blood flow to the heart,
despite no evidence of major blockage in the arteries,
eg, coronary artery spasms, and
spontaneous coronary artery dissection.
A troubling aspect of MINOCA is that
often when we diagnose a heart attack,
we rely on a single imaging method
—invasive coronary angiogram—
to tell us if there’s a big blockage in the coronary arteries.
With MINOCA, the angiogram can look normal.
MINOCA patients are more likely to be female and younger,
and they’re also more likely to be Black or Hispanic/Latino.
