摘要: Background— ST-segment elevation (ΣSTe) recovery and the angiographic myocardial blush (MB) grade are useful markers of microvascular reperfusion after recanalization infarct-related artery. We investigated ability a combined analysis MB ΣSTe changes to identify different patterns shortly primary percutaneous coronary angioplasty (PTCA) predict 7-day 6-month left ventricular (LV) functional recovery. Methods Results— were evaluated successful PTCA (restoration TIMI 3 flow) in 114 consecutive patients with acute infarction. LV function was assessed by 2D echocardiograms before at 7 days 6 months thereafter. By combining changes, main groups identified. Group 1 (n=60) had both significant (grade 2 3) (>50% versus basal ΣSTe) high rate (65%) (95%) functional...
