The Evaluation of Guidelines in Syncope Study score (EGSYS score) is a clinical tool designed for risk stratification in patients presenting with syncope. The primary purpose of the EGSYS score is to identify patients at higher risk of cardiovascular events and mortality, thereby guiding further diagnostic workup and management.
The EGSYS score incorporates several key components, including the presence or absence of palpitations before syncope, abnormal electrocardiogram (ECG) findings or heart disease, syncope during physical exertion, and syncope in a supine position. Each of these factors contributes positively to the score, indicating an increased risk. Conversely, the presence of autonomic prodromes such as nausea or vomiting, and predisposing or precipitating factors like a warm or crowded environment, prolonged orthostasis, or emotional triggers, contribute negatively to the score, suggesting a lower risk.
The EGSYS score, therefore, provides a comprehensive assessment of the patient's syncope episode, integrating both positive and negative risk factors to yield a final score that aids in clinical decision-making.
