Poor efficacy of intravenous thrombolysis in de Winter pattern: A case report.

de Winter syndrome is a strong indication of severe coronary artery disease, requiring rapid identification and opening of coronary vessels to restore blood flow. For patients admitted to hospitals with PCI capacity or transferred primary PCI <2 hours, primary PCI should be performed as soon as possible. Thrombolysis can still be considered for patients first diagnosed in non-PCI institutions with transport time >2 hours, but its efficacy remains to be discussed and further verified.
