International Journal of Traditional Chinese Medicine 2017;39(7):587-591
Objective To investigate the effects of sodium tanshinone ⅡA injection on myocardial enzymes and heart function of patients with acute myocardial infarction, and to explore its therapeutic mechanism. Methods A total of 217 patients with acute myocardial infarction in Taihe Hospital emergency department were randomly divided into control group (n=110) and the Tanshinone group (n=107). The control group was treated by thrombolysis, vascular dilation, antihypertension, anti-shock and other conventional treatment. On the basis of control group treatment, Tanshinone group added the intravenous injection 20mg sodium tanshinone injection. The ELISA was used to test serum creatine kinase (CKMB), superoxide dismutase (SOD), malondialdehyde (MDA) and cardiac troponin I (CTNI) and other enzymes indexes before and after treatment. The heart function were assessed by measuring the left ventricular patient of maximum rising/ falling rate (± LVdp/dtmax),left ventricular end-diastolic diameter (LVDD), left ventricular ejection fraction (LVEF),systolic blood pressure (SP), diastolic blood pressure (DP), pulse pressure (PP ) and heart rate (HR) and other indicators. Results After treatment, the CK-MB (10.76 ± 1.02 mmol/L vs. 15.17 ± 1.21 mmol/L, t=3.724), CTNI (0.11 ± 0.02 ng/ml vs.1.51 ± 0.05 ng/ml, t=2.570), MDA (4.54 ± 0.23 nmol/ml vs. 9.98 ± 1.37 nmol/ml, t=5.035) in the Tanshinone group were significantly lower than those in the control group (P<0.05). The SOD (452.27 ± 21.56 U/L vs. 209.50 ± 15.43 U/L, t=3.935), LVDD (50.74 ± 5.36 mm vs. 44.91 ± 5.31 mm, t=2.454) and LVEF (4.59% ± 0.17% vs. 3.64% ± 0.11%, t=4.052) in the Tanshinone group were significantly higher than those in the control group (P<0.05). The heart function of +dp/dtmax (3742 ± 162 mmHg/s vs. 3948 ± 193 mmHg/s, t=3.731), -dp/dtmax (3512 ± 135 vs. 3847 ± 181, t=3.025), PP (30.5 ± 5.3 mmHg vs. 35.8 ± 5.1 mmHg, t=2.902), DP (99.2 ± 8.8 mmHg vs. 117.3 ± 10.8 mmHg, t=4.079) in the Tanshinone group were significantly lower than those in the control group (P<0.05). The total effective rate was 98.14% (105/107), the control group was 87.2%(96/110), and there was significant difference between the 2 groups (χ2=10.417, P<0.05). Conclusions The Tanshinone ⅡA sodium injection can improve myocardial enzymes and heart function of patients with acute myocardial infarction, which refered to its protective effect on acute myocardial infarction.
