WebbNo reflow is regarded as independent predictor of death or recurrent myocardial infarction. No reflow is a multi-factorial phenomenon. However micro embolization of atherothrombotic debris during PCI remains the principal mechanism responsible for microvascular obstruction.

It is associated with considerable reduction of the myocardial salvage by primary PCI in patients with STEMI. Because reduced myocardial salvage results in larger myocardial necrosis, no-reflow subsequently influences left ventricular function and mortality.
