Acetaminophen-Induced Type II Kounis Syndrome: A Case Report Highlighting Diagnostic Challenges and the Utility of a Physician-Staffed Rapid Response Car
Abstract
Kounis syndrome (KS) is a clinical condition where anaphylaxis induces acute coronary syndrome. This report describes a case of Type II KS in an 85-year-old male, triggered by intravenous acetaminophen, resulting in total occlusion of the right coronary artery. The intervention of a physician-staffed rapid response car (RRC) facilitated early pre-hospital diagnosis of ST-segment elevation myocardial infarction (STEMI). This enabled an integrated transition to emergency percutaneous coronary intervention (PCI). The case demonstrates the utility of advanced pre-hospital systems in managing the therapeutic conflicts associated with KS.
