Management of Wellens Syndrome ECG Pattern

Introduction to Wellens Syndrome

Patients presenting with Wellens syndrome ECG pattern require urgent coronary angiography with revascularization, as this pattern indicates critical proximal LAD stenosis with imminent risk of massive anterior wall myocardial infarction, according to the American Heart Association 1, 2, 3

The ECG pattern of Wellens syndrome is characterized by deeply inverted symmetrical T waves ≥2 mm in leads V1-V4, often extending to V5, as defined by the American College of Cardiology 1, 2
QT prolongation frequently accompanies these changes, as noted by the American Heart Association 1, 2

Establish IV access and continuous cardiac monitoring, as recommended by the American College of Cardiology 4
Administer aspirin 162-325 mg immediately, according to the American College of Cardiology 3
Measure vital signs and assess hemodynamic stability, as recommended by the American College of Cardiology 3

Patients with Wellens syndrome require urgent intervention regardless of TIMI risk score or cardiac biomarker levels, as stated by the American Heart Association 1, 2, 4, 3

Proceed directly to urgent coronary angiography within hours, not days, as recommended by the American College of Cardiology 1, 2
Revascularization (PCI with drug-eluting stents or CABG for multivessel disease) will reverse both T-wave inversions and wall motion abnormalities, according to the American Heart Association 1, 2

Critical stenosis typically occurs in proximal LAD, as noted by the American College of Cardiology 1, 2
Collateral circulation often presents, explaining pain-free presentation, as stated by the American Heart Association 1, 2

Fibrinolytic therapy is contraindicated in this non-STEMI presentation, as recommended by the American College of Cardiology 4, 5, 3
Stress testing is contraindicated and dangerous—these patients require direct angiography, according to the American Heart Association 1, 2

Intracranial hemorrhage (CVA pattern produces similar deep T-wave inversions with QT prolongation) should be excluded, as noted by the American College of Cardiology 1, 2
Takotsubo cardiomyopathy (normal coronaries on angiography, apical ballooning on echo) should be considered, according to the American College of Cardiology 3
Pulmonary embolism with right-sided changes should be ruled out, as recommended by the American College of Cardiology 4, 3

Beta-blocker and ACE inhibitor/ARB should be administered as tolerated, according to the American College of Cardiology 4, 3
Successful revascularization typically results in complete resolution of symptoms and ECG changes, as stated by the American Heart Association 1, 2

In patients with the Wellens ECG pattern, obtain serial high‑sensitivity troponin measurements immediately; a normal result does not exclude the diagnosis. European Society of Cardiology (ESC) non‑ST‑elevation ACS guideline – Class I recommendation. 6

Perform urgent coronary angiography within hours of presentation, irrespective of TIMI risk score or biomarker levels, because the ECG pattern signifies critical proximal LAD stenosis. ESC non‑ST‑elevation ACS guideline – Class I indication for immediate invasive management. 6
