Abstract

Wellens syndrome or also called anterior descending T wave syndrome, described for the first time in 1982 by Wellens and Zwaan, as a subtype of high-risk unstable angina that progresses to myocardial infarction in the anterior face, which can be massive and fatal; Documentation of this pattern on the ECG would be essential to initiate pharmacological treatment and priority referral to the hemodynamics room; A case of a 74-year-old male patient is described who begins symptoms in the early morning with typical chest pain and adrenergic discharge that progressively disappears. The patient is sent to a High Specialty Medical Center for Catheterization, which correlates injury in a rare anatomical site of the middle segment of the anterior descending artery. Knowledge of Wellens Syndrome in the emergency room is of utmost importance to reduce morbidity in patients and avoid its consequences, as well as the importance of primary referral for cardiac catheterization.
