Kounis syndrome links acute coronary events with allergic reactions. It presents as allergic angina or myocardial infarction, with two subtypes based on coronary artery disease presence and mechanism.
Area of Science:
- Cardiology
- Allergy and Immunology
- Pathophysiology
Background:
- The link between acute coronary events and allergic reactions has been recognized since 1950.
- Kounis syndrome, described in 1991, encompasses allergic angina and myocardial infarction.
- It involves diverse triggers, including medications, environmental factors, and medical conditions.
Purpose of the Study:
- To review the pathobiology of Kounis syndrome.
- To outline the clinical features and associated conditions.
- To discuss current management strategies for Kounis syndrome.
Main Methods:
- Review of existing literature on Kounis syndrome.
- Analysis of reported cases and associated conditions.
- Synthesis of information on pathophysiology, clinical presentation, and treatment.
Main Results:
- Kounis syndrome has two subtypes: Type I (coronary spasm in non-CAD patients) and Type II (plaque erosion/rupture in CAD patients).
- Associated conditions include Takotsubo cardiomyopathy, drug-eluted stent thrombosis, and coronary allograft vasculopathy.
- The syndrome highlights the complex interplay between allergic responses and cardiovascular events.
Conclusions:
- Kounis syndrome represents a distinct entity linking allergy and acute coronary syndromes.
- Understanding its subtypes and associated conditions is crucial for diagnosis and management.
- Further research is needed to elucidate its full spectrum and optimize therapeutic approaches.

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
