Abstract：Objective: To explore value of rhBNP treatment efficacy in patients with acute heart failure by using two-dimensional speckle tracking imaging techniques. Methods: Eighty cases of acute heart failure patients were randomized into observe group(rhBNP) and control group(n=40 each), all the patients were treated with traditional heart failure treatment, but the observe group received rhBNP. Two groups of patients with left ventricular ejection fraction(LVEF), left ventricular long axis of the average total strain(GLS-Avg), peak twist(Ptw）, peak untwist velocity(PutwV), and the time to peak twist(TPK) were observed. Results: After treatment, the LVEF, GLS-Avg absolute value, Ptw and PutwV of patients in two groups were increased, but the increasing degree of the observation group was significantly higher than those of the control group, the difference was statistically significant(P<0．05). TPK of patients in two groups were delayed, but the delaying degree of the observation group was significantly higher than those of the control group, the difference was statistically significant(P<0．05). The parameters in the observe group after treatment has improved, the difference was statistically significant(P<0.05). The parameters in the control group after treatment were improved, but there was no statistically significant difference compared with before treatment(P>0.05). Conclusion: rhBNP has a positive and efficient effects on the patients in clinical. At the same time, 2D-STI can provide an effective and noninvasive method for clinical evaluation of left ventricular function．
