Alternation in the Coronary Blood Flow Velocity Pattern in Patients With No Reflow and Reperfused Acute Myocardial Infarction

Abstract

The coronary flow velocity pattern in patients with the no-reflow phenomenon was characterized by the appearance of systolic retrograde flow, diminished systolic antegrade flow, and rapid deceleration of diastolic flow. Thus, the Doppler guidewire allows us to assess the presence of microvascular dysfunction in AMI.
