Patients in the control group were routinely treated. Patients in the Xinmailong group were additionally treated with Xinmailong injection in addition to routine treatment. Before and 3 months after treatment, G-MPI was used to determine changes in the left ventricular ejection fraction(LVEF), left ventricular end-diastolic volume(LVEDV) and left ventricular end-systolic volume(LVESV). Fourteen days after treatment, changes in plasma brain natriuretic peptide(BNP) levels were determined.RESULTS: Before treatment, there were no significant differences in LVEF, LVEDV, LVESV, and BNP levels between the two groups(all P>0.05). After treatment, LVEDV, LVESV, and BNP levels were significantly lower, and LVEF was significantly higher in the Xinmailong group than in the control group(all P<0.05).CONCLUSION: Additional use of Xinmailong injection in addition to routine treatment improves cardiac function of CHF patients. Because of the safety and effectiveness of Xinmailong injection, this therapy should be promoted.展开更多
