Treatment of LLTS significantly attenuated the occurrence of reperfusion associated ventricular arrhythmia during first 24 h. The area under curve for level of creatine kinase-MB and myoglobin were significantly reduced by LLTS 72 h after reperfusion. In addition, level of NT-proBNP was significantly reduced by LLTS at 24 h and 7 days post-reperfusion. Significant improvements of inflammation, LVEF and wall motion index were observed as well in LLTS group. Here, MB is linked to Ventricular arrhythmia.
