May influence post-MI spasm assessment by ethnicity; leaves open whether this alters prognosis or therapy.
Does coronary constrictor response to acetylcholine differ between Japanese and Caucasian patients early after acute myocardial infarction?
Japanese patients exhibit a significantly higher incidence of coronary spasm and vasoconstriction early after acute myocardial infarction compared to Caucasians, highlighting important racial differences in coronary vasomotion.
