distal stenosis or occluded small branches), and 3) nonischemic causes for myocyte injury (e.g., Spontaneous coronary artery dissection (SCAD) should be considered as a cause of MINOCA.

Marked differences can be seen in the prevalence of coronary artery stenosis at autopsy by age and gender. In 30-39 year old women the rate of coronary stenosis at autopsy was 5/1,545 (0.3%) while 60-69 year old men had a prevalence of 12%, almost 40 times higher. The results of this dataset by age and gender follow.
