Objective To observe the effect of low-dose dabigatran etexilate on the clinical efficacy of elderly patients with venous thromboembolism (VTE). Methods Seventy-five elderly (≥ 80 years old) VTE patients admitted to Cangzhou Central Hospital from October 2016 to June 2018 were enrolled, they were treated according to the VTE guidelines, and low dose dabigatran etexilate was the anticoagulant therapy selected, 110 mg once daily for 6 months. After treatment for 6 months, the thrombus regression situation with color Doppler ultrasonography;clinical efficacy was evaluated by clinical symptoms and ultrasonographic results, the changes in platelet count (PLT), coagulation parameters [international normalized ratio (INR), activated partial thromboplastin time (APTT), fibrinogen (Fib)] before and after treatment were detected and the occurrence of adverse reactions were recorded and safety of drug was evaluated. Results There were no significant differences in PLT, INR and Fib before and after treatment [PLT (×109/L): 197.88±58.00 vs. 199.88±65.15, INR: 1.02±0.10 vs. 1.05±0.13, Fib (g/L): 2.89±0.67 vs. 2.84±0.70, all P > 0.05], the APTT after treatment was significantly prolonged compared with that before treatment (seconds:40.9±7.34 vs. 26.2±3.16), the difference being statistically significant (P < 0.05), the amount of APTT prolongation after treatment did not exceed 2 times [average (1.75±0.24) times] of the baseline value before treatment. The total effective rate of low-dose dabigatran etexilate for treatment of elderly patients with VTE for 6 months was 90.7% (68/75);no obvious adverse reactions occurred during the treatment. Conclusion Low-dose dabigatran etexilate for treatment of elderly patients with VTE is safe and effective without any obvious adverse reactions, and is worthy to be promoted for clinical use.

Objective To observe the effects of recombinant human B-type natriuretic peptide (rhBNP) on cardiac function and heart rate variability (HRV) in patients with heart failure after acute myocardial infarction (AMI). Methods One hundred and twenty patients with heart failure after AMI admitted to the Department of Cardiology of Cangzhou Central Hospital of Hebei Province from January 2015 to January 2018 were enrolled. The patients were divided into a conventional treatment group and an rhBNP treatment group according to random number table method, with 60 cases in each group. The two groups were treated according to the AMI guidelines, the conventional treatment group received west medicine anti-myocardial ischemia and anti-heart failure treatment; the rhBNP treatment group received rhBNP on the basis of routine treatment; the first load dose was 2 μg/kg intravenous injection impact treatment, followed by maintaining dose 8.5 ng·kg-1·min-1 intravenous drip for 7 days. The changes of hypersensitivity C-reactive protein (hs-CRP), N-terminal B-type natriuretic peptide precursor (NT-proBNP), left ventricular ejection fraction (LVEF) and HRV index were observed before and after treatment in the two groups [HRV indexes including the changes of average normal RR interval standard deviation (SDNN), the average value of the normal RR interval standard deviation (SDANN), the root mean square (RMSSD) of the adjacent RR interval difference, and the percentage of adjacent RR interval difference > 50 ms (PNN50)]; the incidences of adverse reactions in the two groups were observed. Results After treatment, the levels of hs-CRP and NT-proBNP in the two groups were significantly lower than those before treatment (all P < 0.05). LVEF, SDNN, SDANN, RMSSD and PNN50 were higher than those before treatment, and the changes of the above indicators in the rhBNP treatment group were more significant than those in the conventional treatment group [hs-CRP (mg/L): 6.2±3.3 vs. 11.8±5.5, NT-proBNP (ng/L): 2.5±2.0 vs. 6.4±4.3, LVEF: 0.49±0.02 vs. 0.44±0.04, SDNN (ms): 93.3±18.1 vs. 79.1±16.0, SDANN (ms): 87.3±17.8 vs. 70.9±14.9, RMSSD: 30.3±11.0 vs. 23.8±10.4, PNN50: (15.9±7.3)% vs. (9.6±5.5)%, all P < 0.05]; No significant adverse reactions occurred during the treatment of the two groups. Conclusion rhBNP can significantly improve the heart function of patients with heart failure after AMI, reduce the levels of inflammatory response indicators and improve HRV;since its clinical efficacy is good, and its application safe, it is worthy to promote its clinical use.

Objective To study the effect of corrected TIMI frame count (CTFC) of infarction related artery on systolic function of infarct area of myocardium after primary percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI). Methods One hundred and six patients with AMI having undergone successful PCI in Cangzhou Central Hospital were selected, and they were divided into two groups (each, 53 cases). The standard of fast or slow flow was in accord to the CTFC of infarction related artery (IRA) measured soon after successful PCI. The patients with greater value of CTFC were enrolled in the slow flow group, while the patients with smaller such value were assigned in the fast flow group. At 6, 12, 24 and 48 hours after PCI, the venous plasma MB isoenzyme of creatine kinase (CK-MB) level was measured. And at 1 week, 1 month and 3 months after PCI, the left ventricular ejection fraction (LVEF) was measured by cardiac ultrasound, and the levels of radial strain (RS) and longitudinal strain (LS) of the infarct area were measured via speckle tracking imaging (STI). The differences in CTFC, CK-MB, RS and LS between the two groups were analyzed, and the correlations between the strains and CTFC, CK-MB were analyzed by Pearson linear correlation method. Results After successful PCI, the CK-MB of fast flow group was higher than that of the slow flow group at 6 hours. However, the CK-MB of slow flow group was higher than that of the fast flow group after 12 hours, appearing separate phenomenon, and the statistical significance occurred beginning from 24 hours after PCI (U/L, 24 hours:98.43±11.65 vs. 86.43±18.97, 48 hours:51.09±8.94 vs. 49.80±6.92, both P 0.05). RS and LS in fast flow group were higher than those in slow flow group, and the statistically significant difference appeared from 1 month after PCI (1 month RS:29.74±6.66 vs. 26.86±5.61, LS:-16.37±3.91 vs. -15.27±3.22, 3 months RS: 30.03±6.31 vs. 27.63±5.67, LS: -17.74±3.96 vs. -15.75±4.17, all P 0.05). Both RS and LS at 1 week, 1 month and 3 months were of significantly positive correlation with CTFC of each group (fast flow group:r value of CTFC and RS was respectively-0.526,-0.515,-0.532, r value of CTFC and LS was respectively-0.532,-0.541,-0.572;slow flow group:r value of CTFC and RS was respectively-0.691,-0.685,-0.702, r value of CTFC and LS was respectively-0.621,-0.584,-0.605, all P<0.01). Conclusion CTFC has some relationship with the recovery of the systolic function in area of infarct myocardium after PCI, and can be regarded as an important index to predict the long-term prognosis in patients with AMI.
