The de Winter ECG pattern is a dynamic early manifestation of ACS that indicates severe coronary stenosis and requires urgent coronary angiography.
These two cases and the literature review indicated that the de Winter ECG pattern is dynamically evolving. Its ECG pattern evolution is variable, progressing to STEMI, NSTEMI, Wellens, or even a normal. In patients presenting with chest pain, a de Winter ECG pattern, regardless of the subsequent dynamic evolution of the ECG, indicates the presence of severe coronary artery stenosis. The de Winter ECG pattern may be an early manifestation of ACS and requires urgent coronary angiography to save the patient's life and improve prognosis.
