Figure 1 Relation between six-month change in global wall motion index (WMI) and coronary flow velocity reserve after percutaneous coronary intervention (A) and change in WMI as a function of corrected Thrombolysis In Myocardial Infarction (TIMI) frame count, (B) myocardial blush grade (C), and TIMI flow grade (D). The regression lines and 95% confidence intervals are shown. Change in WMI >0 reflects improvement of left ventricular function after six months.
