This study quantitatively evaluated the change in myocardial blood flow resulting from medical revascularization in patients with acute anterior myocardial infarction. Changes in great cardiac vein flow were measured using a thermodilution technique in 13 patients with acute infarction; 3 received intracoronary streptokinase and 10 percutaneous transluminal angioplasty. Average great cardiac vein flow during left anterior descending coronary artery occlusion was 62 ± 6 ml/min and increased to 70 ± 7 ml/min (p = 0.039) after arterial recanalization. There was significant individual variability in the great cardiac vein flow increments that was highly predictive of functional recovery as expressed by the change in ejection fraction at 7 to 10 days (r = 0.93, p = 0.0008). Incremental great cardiac vein flow was inversely correlated with the degree of residual stenosis and the duration of ischemia (r = 0.88, p = 0.0007). Patients with residual stenosis ≤50% had a significantly larger increase in great cardiac vein flow (14 ± 5 ml/min) than did those with residual stenosis >50% (0 ± 2 ml/min, p = 0.026). Neither preinterventional left ventricular ejection fraction, hemodynamics nor age predicted incremental great cardiac vein flow.Therefore, quantitative measurements of great cardiac vein flow during medical revascularization in patients with an acute anterior myocardial infarction demonstrate variable reflow that is physiologically significant. A high grade residual stenosis and prolonged period of ischemia limit large increases in flow and prevent functional recovery. This study emphasizes the fact that recanalization in itself cannot be used as an indicator of the success of interventions designed to produce myocardial reperfusion.
