Background:
Kounis syndrome (KS) is an underdiagnosed disease. The management of the disease remains elusive because of its infrequency.
Case Presentation:
A 78-year-old man with anaphylactic shock was admitted to our hospital 2 h after multiple bee stings. After recovering from an anaphylactic reaction, he presented with chest pain with ST elevation. We diagnosed him with KS. After a continuous intravenous infusion of vasodilators, his chest pain and ST elevation improved. However, chest pain with ST-segment elevation recurred the next day. Coronary angiography revealed severe stenosis in the middle left anterior descending coronary artery, and drug-eluting stents were implanted. The patient was discharged on foot after treatment for heart failure.
Conclusion:
KS, in which anaphylaxis and acute coronary syndrome occur simultaneously, can recur repeatedly after an initial anaphylactic reaction; however, it could be delayed or it could present simultaneously with the anaphylactic reaction. Therefore, long-term observation is important.

Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...
