Abstract
1021 Relation between the assessment of microvascular injury by cardiovascular magnetic resonance and coronary Doppler flow velocity measurements in patients with acute anterior wall myocardial infarction
Highlights
Cardiovascular magnetic resonance (CMR) has been used to detect and quantify microvascular obstruction (MVO) in patients after acute myocardial infarction but has never been compared to coronary blood flow velocity patterns
We studied the relation between the presence and severity of MVO measured by CMR and intracoronary Doppler flow measurements, for assessment of myocardial reperfusion in patients with acute anterior wall myocardial infarction treated by primary percutaneous coronary intervention (PCI)
The extent of MVO correlated with diastolic-systolic velocity ratio (r = 0.44, p = 0.02), diastolic deceleration time (r = -0.61, p = 0.001), diastolic deceleration rate (r = 0.75, p < 0.0001), and coronary flow velocity reserve of the infarct-related artery (r = -0.44, p = 0.02)
