Objective To compare the effects of ticagrelor and clopidogrel on patients undergoing percutane-ous coronary intervention(PCI)with acute ST elevated myocardial infarction (STEMI).Methods 120 patients with STEMI received PCI within 12h of symptom onset in our hospital were randomly divided into clopidogrel treated group (n=60)and ticagrelor treated group (n=60).Serum was collected before surgery and 36 hours after PCI for ALT, Cr,CK-MB,and MA.Cardiac ultrasound was examined,too.All patients were followed 6 months post-PCI for main adverse cardiovascular and cerebrovascular events (MACCE)and medicine side effect.Results No significantly difference was noted in baseline between the two groups.The level of CK-MB and MA in the ticagrelor treated group [CK-MB(56.5 ±8.3)U/L,MA (45.9 ±6.4)mm[and clopidogrel treated group[CK-MB(74.3 ±9.6)U/L,MA (35.6 ±7.3)mm]were significant difference (CK-MB,P=0.043;MA,P=0.038).The MACCE of patients in ticagrelor treated group were significantly lower than patients in clopidogrel treated group during post-PCI 6 months follow-up(The ratio of angina in ticagrelor group was 1.7%,while in clopidogrel group was 6.7%,P=0.042). Conclusion Ticagrelor is more effective in suppress the function of platelet,decrease MACCE in patients with STE-MI undergoing PCI.

Objective To compare the clinical outcomes of Chinese rapamycin-eluting stents (Firebird stents) and imported paclitaxel-eluting stents ( Taxus stents ) in the treatment of acute myocardial infarction. Methods Ninety-seven patients with ST segment elevated acute myocardial infarction were treated with Firebird stents (in 51 patients) and Taxus stents (in 46 patients). The death rate, re-acute myocardial infarction, target lesion revascularization (TLR) ,and major adverse cardiac event (MACE) within 9 months after percutaneous coronary intervention ( PCI) were observed between the two groups. Results The rate of successful stent-implantation, angina,death, re-acute myocardial infarction, TLR and MACE was 100% ,9. 8% ,0% ,2. 0% ,0% , 11. 8% in the Firebird stent group and 100% ,8. 7% ,0% ,2. 2% ,0% ,0% and 10.9% in the Taxus stents group within 9 months after PCI. There was no significant difference between the two groups. Conclusions There is no significant difference in the clinical effect between the Firebird stent group and Taxus stent group within 9 months after PCI. However, the effect-cost ratio is better in the Firebird stent than the Taxus stent.

BACKGROUNDRadiofrequency catheter ablation (RFCA) for atrial fibrillation (AF) has developed rapidly, and is a commonly performed ablation in many major hospitals throughout the world, due to its satisfactory results. The aim of this study was to detect the effect of RFCA on C-reactive protein (CRP), brain natriuretic peptide (BNP), and echocardiograph in patients with persistent and permanent AF.

METHODSA total of 120 patients (71 males, mean age (50.8 ± 12.0) years) with persistent and permanent AF undergoing RFCA under guidance of the Carto merge technique were studied. Left atrial diameter (LAD), right atrial diameter (RAD), left ventricular ejection fraction (LVEF), CRP, and BNP were observed 3, 6 and 12 months after RFCA and compared with results before RFCA. The recurrence of atrial arrhythmias was observed 3 and 12 months after the procedure.

RESULTSCompared with that before RFCA, LAD and RAD decreased and LVEF increased significantly after RFCA. Meanwhile, the levels of CRP and BNP were reduced significantly at 3, 6, and 12 months after RFCA (P < 0.05). In the non-recurrent patients, LVEF was increased significantly compared with the recurrent patients at 3, 6, and 12 months after RFCA (P < 0.05). CRP and BNP levels were decreased significantly in the non-recurrent patients compared with the recurrent patients at 3, 6, and 12 months after RFCA (P < 0.05). After one or two applications of RFCA, during a follow-up of 12 months, 12 patients (10.0%) had AF, 10 patients (8.3%) had atrial flutter, and 5 patients had atrial tachycardia (4.2%).

CONCLUSIONSConversion of AF to sinus rhythm by RFCA, has been shown to reduce LA size and improve LVEF. It can also significantly decrease the levels of CRP and BNP in patients with persistent and permanent AF and reduce the risk of inflammation and developing heart failure.

Objective: To explore the relationship between liver controlled attenuation parameters (CAP) and body fat mass and its distribution. Methods: From May to December 2018, 978 adult patients visited at the fatty liver center of the Third People's Hospital of Changzhou were treated. The patient's liver controlled attenuation parameters were measured by transient elastography and the body fat mass and its distribution were measured by bioelectrical impedance technology. Pearson’s correlation coefficient was adopted to describe the correlation between liver CAP value and body mass index (BMI), body fat mass index (BFMI), trunk fat mass index (TFMI), limbs fat mass index (LFMI) and visceral fat area (VFA). Receiver operating characteristic curve (ROC) and area under the curve (AUC) were used to evaluate BMI, BFMI, TFMI, LFMI and VFA to differentiate the cut-off points and efficacy of CAP for diagnosing grading of fatty liver changes in S0-1 and S2-3. Results: In 653 cases of male, S0 ~ S3 accounted for 4.90%, 3.37%, 22.36% and 69.37%, respectively, and in 325 cases of females, S0 ~ S3 accounted for 7.38%, 6.46%, 13.23% and 72.92%, respectively. Female patients had more visceral, trunk and limbs fat than male (P < 0.01). Body mass, body fat mass, body fat percentage, BMI, BFMI, TFMI, LFMI, and VFA were increased in male and female patients with increasing liver fat grade (P < 0.01). CAP values ​​of male and female patients were positively correlated with BMI, BFMI, TFMI, LFMI and VFA. Percentage of body fat mass increased with increasing liver fat grade (male: F = 13.42, P < 0.001; female: F = 3.22, P = 0.023); while limb fat mass percentage did not increase with liver fat grade (Male: F = 1.13, P = 0.34; female: F = 1.05, P = 0.37). Hepatic steatosis grading (S0 ~ 1 or S2 ~ 3) diagnosed with CAP were distinguished through BMI, BFMI, TFMI, LFMI and VFA. AUC was 0.80 ~ 0.82 in males (P < 0.01), and 0.75 ~ 0.78 in females (P < 0.01). Conclusion The liver CAP value is positively correlated with the body's limbs, trunk and visceral fat, and has a strong correlation with trunk and visceral fat. BMI, BFMI, TFMI, LFMI and VFA up to some extent can identify the CAP diagnosis of grading of fatty liver changes in S0-1 and S2-3.
