Results: The improvement on chest stuffiness, short breath, fatigue and spontaneous perspiration in the treatment group was better than those in the control group (P < 0.05) and XYK showed obvious improving effect on ESR, AST, LDH, CPK and CPK-MB (P < 0.01 or 0.05). There was no adverse reaction or side-toxic effects revealed in using XYK.
