Abstract | OBJECTIVES: METHODS: Thirty three patients with first anterior wall myocardial infarction underwent primary coronary angioplasty and achieved reflow within 8 hr of onset. By using a Doppler guide wire, CFV patterns were assessed immediately after primary coronary angioplasty. T1/ BMIPP dual scintigraphy was performed within 3 days after reperfusion. The extent of discordance in severity score was defined as the T1/ BMIPP mismatch score. RESULTS: Regression analysis showed dual scintigraphy mismatch score correlated well with deceleration time of diastolic flow velocity (r = 0.54, p < 0.01). Mismatch score was greater in the non-early systolic reversal flow group than in the early systolic reversal flow group (5.5 +/- 3.3 vs 1.9 +/- 2.1, respectively, p < 0.01). CONCLUSIONS: Changes in CFV patterns correlated well with T1/ BMIPP mismatch score. CFV pattern immediately after reperfusion is useful for early prediction of myocardial salvage.
