Transient U wave inversion during variant angina.

abstract：BACKGROUND:No-reflow after primary percutaneous coronary intervention (PCI) in ST-elevation myocardial infarction (STEMI) is associated with poor prognosis. Endothelin-1 (ET-1) is a potent endothelium-derived vasoconstrictor that might aggravate reperfusion injury. The aim of our study was to assess the relationship be...
