The usual treatment of ACS is recommended as an initial treatment, although in type I variant the treatment of the allergic reaction could be enough. [journals.viamedica.pl]

Inflammatory mediators such as histamine constitute the pathophysiologic basis of Kounis hypersensitivity-associated acute coronary syndrome. [tandfonline.com]
The pathophysiology is thought to be mediated by the induction of inflammatory cytokines, after an allergic insult that potentiates coronary vasospasm, plaque rupture or in-stent thrombosis. [jacc.org]
