Abstract

Allergic reactions are a wide-spectrum condition that can range from a simple symptom to a fatal shock. It still maintains its mystery in the pathophysiological sense today. Kounis syndrome is an allergic reaction that is related to coronary arteries and can lead to myocardial infarction and be fatal. Due to the uncertainty of its mechanism and low incidence, it cannot be clearly predicted in which situations and for what reason patients will encounter this disease. Kounis syndrome, which will be further clarified as case reports increase, was encountered in this case in a young patient who applied to the emergency department with the complaint of dysmenorrhea. Diclofenac sodium was injected intramuscularly to the patient due to dysmenorrhea. After the injection, the patient was monitored because she did not feel well and had shortness of breath. An electrocardiogram (ECG) was taken when an irregular rhythm was seen on the monitor. ECG showed widespread ST depressions and arrhythmia. In the blood taken, the high-sensitive troponin I value was found to be 10 times higher than normal. Coronary artery disease was not detected in the patient for whom coronary angiography was recommended. Our case was described as type 1 kounis syndrome.
