Wellens' syndrome is characterized by T-wave changes in electrocardiogram (EKG) 
during pain-free period in a patient with intermittent angina chest pain. It 
carries significant diagnostic and prognostic value because this syndrome 
represents a pre-infarction stage of coronary artery disease involving proximal 
left anterior descending (LAD) artery, which can subsequently lead to extensive 
anterior myocardial infarctions (MIs) and even death without coronary 
angioplasty. Therefore, it is crucial for every physician to recognize EKG 
features of Wellens' syndrome in order to take appropriate immediate 
intervention to reduce mortality and morbidity for MI. Here, we report a case of 
an overweight man with 35 pack-year of smoking history who presented to Easton 
Hospital with intermittent pressing chest pain of 5/6 times within 10 day-period 
and was found to have type A Wellens' sign, which was biphasic T-waves in 
precordial leads V2 and V3 during pain-free period with no cardiac enzymes 
elevation. He was given therapeutic lovenox and subsequently underwent coronary 
angioplasty and had 95-99% occlusion in proximal LAD artery. The unique feature 
of our case was that Wellens' type B EKG changes were seen after reduction of 
stenosis with LAD artery stent, which was likely explained by the reperfusion of 
the ischemic myocardium. Therefore, it is important for physicians to recognize 
EKG features of Wellens' syndrome in order to take appropriate therapy to 
reducing mortality and morbidity form impending MI.
