RESUMO
Objective: To detect the changes of serum level of connective tissue growth factor (CTGF) in patients with ST-segment elevation myocardial infarction (STEMI) and to study the correlation between CTGF level and the maximal activity of creatine kinase-MB (CK-MB). Methods: Our research included 2 groups of patients: STEMI group and unstable angina (UA) group. All patients were treated in our hospital from 2013-07 to 2014-06,n=50 in each group. In STEMI group, the serum levels of CTGF were examined by ELISA at 24h, 2, 7, 14 days of onset, and in UA group, CTGF level was examined at 24h of onset. The CK-MB activity levels were measured in STEMI group at the same time points by immunosuppression method. Results: The serum level of CTGF in UA patients at 24 h of onset was (10.34 ± 2.00) ng/mL, and in STEMI patients were (16.76 ± 3.17) ng/mL at 24h, (29.87 ± 4.90) ng/mL at 2d, (45.02 ± 8.35) ng/mL at 7d and (31.61 ± 4.40) at 14d. The CTGF levels in STEMI group at different time points were all higher than UA group at 24h of onset,P<0.01. In STEMI group, the CTGF levels were increasing from 24h to 7d, then decreasing at 14d, allP<0.01. In STEMI group, the highest protein concentration of CTGF was positively related to the maximal activity of CK-MB at 7 days of onset (r=0.859,P=0.000). Conclusion: CTGF expression has been up-regulated in STEMI patients which might be related to myocardial ifbrosis. The protein level of CTGF is related to MI size, it shows certain predictive value in relevant patients.
RESUMO
Objective: To explore the clinical and anatomical characteristics of coronary slow lfow (CSF) in relevant patients. Methods: We summarized the patients without coronary angiography (CAG) proved coronary stenosis (stenosis 27 and Control group,n=55 patients with normal coronary lfow. The related laboratory indexes were examined and relationship between MCV and CSF was studied by multi-logistic regression analysis. Results: In CSF group, MCV 90.4 (87.48, 92.65) fL and RDW-CV 12.5 (12.30, 13.18) % were lower than those in Control group 92.3 (90.1, 94.3) fL and 13(12.7, 13.4) %,P Conclusion: Deformability of red blood cells might be involved in pathogenesis of CSF in relevant patients.
RESUMO
Objective To evaluate the effect of homemade tirofiban in percutaneous coronary intervention for acute myocardial infarction. Methods Sixty four cases of consecutive acute myocardial infarction were enrolled and divided into two groups: the tirofiban group (n=34) and the control group (n=30). In addition to intravenous heparin, patients in the tirofiban group received a bolus dose of tirofiban (10 ?g/kg) before stenting and followed by a 0.15 ?g/(kg?min) infusion for up to 12-36 hours. The control group only receive routine intravenous heparin therapy before and during PCI. The post operation TIMI blood flow, bleeding events and major adverse cardiac events were observed in the 2 groups. Results A 97.1% of patients in the tirofiban group compared with 76.7% in the control group obtained TIMI grade 2-3 flow respectively. Among them, 91.2% in the tirofiban group but 70.0% in the control obtained TIMI 3 flow. There were no serious in-hospital bleeding complications and MACE. Conclusion Homemade tirofiban is effective in improving the TIMI grade and prognosis of acute myocardial infarction after PCI.
RESUMO
Objective To investigate the relation of inflammation markers to acute coronary syndrome and the clinical significance by observing the changes of P selectin、CRP 、IL 6、TNF ?、ICAM 1 during unstable agina pectoris and acute myocardial infarction(AMI). Methods 45 patients were selected as acute coronery syndrome(ACS)group, including 25 patients with unstable agina pectoris (UAP) and 20 patients with AMI; 25 patients as stable agina pectoris (SAP)and 20 persons as control group. The blood sample of the control group are drawn from venous in the morning, the agina pectoris group are drown from venous in the morning of the second day after hospitalized, however, the AMIgroup are drown from venous at the point of 6 hour、 12 hour、24 hour、48 hour、72 hour after episode. The concentration of CRP is determined by Scatter Turbidimetry , and the concentration of P selectin、IL 6 、TNF ?、ICAM 1 by ELISA. Results (1) SAP vs control ,the levels of P selectin、CRP 、IL 6、TNF ?、ICAM 1 all raise significantly ( P 0.05) ; (4) AMI vs SAP , the levels of P selectin、CRP 、IL 6、TNF ?、ICAM 1 all raise significantly ( P
