Introduction: Wellens Syndrome (WS) is an unusual electrocardiographic diagnosis characterized by changes in the T wave specific to severe stenosis at a proximal level of the anterior descending coronary artery (LAD). Therefore, early diagnosis is important, because of the large area of myocardium at risk, which generally represents poor prognosis indicator. Case report: In this series we describe two patients admitted with typical angina pain without changes in the electrocardiogram (EKG). However, even though patients were not having pain, typical changes, characteristic of this síndrome, appeared in the EKG, with normal troponin levles. Both cases had percutaneous coronary intervention (PCI) that prevented extensive anterior AMI, since severe LAD proximal lesions were found. Evolution: Both patients were admitted to the coronary care unit and discharged without complications. After PCI, the first patient had na EKG showing persistent inverted T waves. A followup echocardiogram, performed 2 months later, revealed an ejection fraction of 54%. The second patient had a post-PCI EKG showing an incomplete resolution of the inverted T waves, whereas the follow-up echocardiogram showed an ejection fraction of 60%. Discusion: Both cases showed the importance of an invasive strategy as the best treatment of choice. We should also be careful no to refer these patiens to exercise stress tests, to avoid sudden death.
