What is Wellens syndrome?

• A. Decreased blood flow in the right coronary artery
• B. Critical stenosis of the left anterior descending coronary artery
• C. Acute coronary syndrome
• D. Cardiac arrest

Answer: (B)

Wellens syndrome is characterized by specific EKG findings that indicate critical stenosis of the left anterior descending coronary artery, typically manifested as deeply inverted or biphasic T waves in the anterior leads (V2 and V3). This condition is a warning sign of impending myocardial infarction, especially in patients with chest pain who present with these EKG changes. The identification of Wellens syndrome is crucial since it indicates a high risk for coronary events and often necessitates urgent intervention or monitoring.

Understanding the implications of Wellens syndrome helps in recognizing that while the patient may not present with sustained chest pain at the time of the EKG, the underlying severe stenosis poses a significant risk of acute coronary syndrome if not addressed. Consequently, timely identification and management can improve outcomes in patients with this syndrome.
