Kounis Syndrome: Causes, Symptoms, And Treatment
Kounis syndrome, also known as allergic angina or allergic myocardial infarction, is a rare condition triggered by an allergic reaction. This unique syndrome occurs when the body's immune system responds to an allergen by releasing chemicals that can cause sudden chest pain or even a heart attack. It is crucial to identify and avoid potential allergens to prevent the onset of Kounis syndrome. By understanding the triggers and taking appropriate precautions, individuals can reduce the risk of experiencing this serious allergic reaction affecting the heart.
What Are the Symptoms of Kounis Syndrome
Kounis syndrome symptoms include chest pain, shortness of breath, dizziness, and fainting. Patients may experience nausea, vomiting, and sweating. Skin rash and itching are also common. Severe allergic reactions can lead to low blood pressure and heart rhythm abnormalities. Seek immediate medical attention if experiencing these symptoms after exposure to an allergen.
- Chest pain and tightness: People with Kounis syndrome may experience sudden chest discomfort or a feeling of pressure, often mistaken for a heart attack.
- Shortness of breath: Breathing difficulties, wheezing, or gasping for air can occur in individuals having an allergic reaction that triggers Kounis syndrome.
- Skin rash or hives: Some patients may develop red, itchy skin rashes or raised welts on their body as a result of the allergic response in Kounis syndrome.
- Dizziness or fainting: Feeling lightheaded, dizzy, or passing out can be a symptom of Kounis syndrome, especially when the allergic reaction affects blood flow.

It can be triggered by various allergens such as insect bites, foods, medications, or environmental factors. The release of inflammatory mediators during the allergic response can result in acute coronary events, making it a serious condition that requires prompt medical attention.
- Allergic reactions to medications such as antibiotics, non-steroidal anti-inflammatory drugs (NSAIDs), or contrast agents can trigger Kounis syndrome.
- Stings or bites from insects like bees, wasps, or ants are common causes of Kounis syndrome.
- Consuming certain foods, particularly shellfish, nuts, or eggs, can lead to an allergic response that results in Kounis syndrome.
- Exposure to environmental allergens like pollen, dust mites, or animal dander may provoke an allergic reaction leading to Kounis syndrome.
- Physical factors such as exercise-induced anaphylaxis or cold-induced urticaria can also be underlying causes of Kounis syndrome.
Types Of Kounis Syndrome
- Type 1 Kounis syndrome, also known as allergic angina syndrome, is characterized by the development of chest pain (angina) due to allergic reactions, typically triggered by foods, medications, or insect stings.
- Type 2 Kounis syndrome involves acute coronary events, such as heart attacks or unstable angina, occurring in individuals with pre-existing coronary artery disease triggered by allergic reactions.
- Type 3 Kounis syndrome, also called vasospastic angina with allergic shock, manifests as severe allergic reactions leading to systemic vasospasm and potentially life-threatening conditions like anaphylactic shock and myocardial ischemia.
Risk Factors
Risk factors for Kounis syndrome include a history of allergies, especially to medications or insect stings, pre-existing cardiovascular disease, and a family history of heart conditions. Factors such as a previous myocardial infarction, hypertension, or smoking can also increase the risk of developing this condition. Identifying and managing these risk factors is crucial in preventing Kounis syndrome episodes.
- Individuals with a history of allergic reactions, particularly to medications or insect stings, are at increased risk for developing Kounis syndrome.
- Patients with a known history of coronary artery disease or other cardiovascular conditions are more susceptible to experiencing Kounis syndrome.
- People with a family history of heart conditions or allergic reactions may have a higher predisposition to developing Kounis syndrome.
- Those with poorly controlled asthma or other respiratory conditions have an elevated risk of experiencing Kounis syndrome during an allergic reaction.
- Patients undergoing procedures involving the use of contrast media or other allergenic substances are at heightened risk for developing Kounis syndrome.

Diagnosis of Kounis Syndrome
Kounis syndrome is diagnosed by a doctor through a combination of your symptoms, medical history, physical examination, and possibly blood tests or an electrocardiogram (ECG). The doctor will look for signs of allergic reaction and heart problems, as this condition involves both. It's important to seek medical help right away if you suspect you may have Kounis syndrome to receive proper diagnosis and treatment.
- Electrocardiogram (ECG) is a primary diagnostic tool used to identify abnormal heart rhythms and changes in the heart's electrical activity in patients suspected of having Kounis syndrome.
- Blood tests to measure cardiac enzymes, such as troponin and creatine kinase-MB, can help confirm myocardial injury and assess the extent of cardiac damage in individuals with Kounis syndrome.
- Echocardiography is commonly performed to evaluate heart function, detect abnormalities in the heart's structure, and assess the presence of any complications like heart failure or pericardial effusion in Kounis syndrome patients.
- Coronary angiography is a valuable diagnostic procedure that allows visualization of the coronary arteries to detect any block.
Treatment for Kounis Syndrome
Treatment for Kounis syndrome involves managing the allergic reaction that is causing the symptoms. This may include administering medications such as antihistamines, corticosteroids, and adrenaline. In severe cases, emergency medical attention may be needed to stabilize the patient's condition. It is important to avoid triggers that may cause the allergic reaction and to follow up with a healthcare provider for further management.
- Prompt administration of epinephrine is crucial in managing Kounis syndrome, as it helps counteract the severe allergic reaction and stabilizes blood pressure and heart rate.
- Antihistamines such as diphenhydramine can be given to alleviate itching and hives associated with Kounis syndrome, providing symptomatic relief.
- Corticosteroids like prednisone may be prescribed to reduce inflammation and prevent further allergic reactions in patients with Kounis syndrome.
- In severe cases of Kounis syndrome, intravenous fluids and medications to support blood pressure and cardiac function may be necessary to stabilize the patient's condition.
- Long-term management of Kounis syndrome often involves identifying and avoiding triggers
