Wellens Syndrome is a condition that indicates a critical narrowing of the proximal left anterior descending (LAD) artery. It is considered a pre-infarction state, meaning that patients with this syndrome are at high risk of developing a large anterior myocardial infarction (MI) if not treated promptly. Wellen’s syndrome, also called LAD coronary syndrome or widow maker, was first described in 1982 by de Zwaan et al 1 in a subgroup of patients with unstable angina during a pain-free period. Recognizing this syndrome is crucial for clinicians, as it demands urgent intervention to prevent a potentially catastrophic outcome. This article aims to provide a comprehensive understanding of Wellen’s syndrome, including its clinical significance, diagnostic criteria, management, and implications for patient care. Case presentation. Wellens syndrome is an acute coronary syndrome (ACS) characterized by isolated T-wave changes and evolution in the electrocardiogram (ECG), also known as the anterior descending branch T-wave syndrome.
