Sex Differences in Coronary Artery Disease Characteristics Among Patients With Type 2 Myocardial Infarction
Authors' conclusion
Among patients with type 2 MI, prevalence of any CAD and obstructive CAD did not differ according to sex. Total plaque volume was similar between sexes, but women had a lower volume of low-attenuation plaque
