  • ROLES OF PLACENTAL GROWTH FACTOR IN PERCUTANEOUS CORONARY ANGIOPLASTY AND STENTIMPLANTATION

    To investigate the value of plasma placental growth factor (PlGF) in percutaneous coronary angioplasty and stent implantation. Methods From May 2006 to March 2007, 61 patients (53 males and 8 females, mean age61 years) and 28 normal controls were included. All patients present with acute chest pain and underwent coronary angiography, the lesion severity of coronary arteries was assessed by Gensini coronary scoring system. Of them, 26 patients having serious coronary lesion underwent (percutaneous transluminal coronary angioplasty, PTCA) and stent implantation. Cardiovascular events were recorded after 30 days. Plasma PlGF was determined by ELISA. Results According to the angiography, the patients could be divided into CAD group (n=45) and Non- CAD group (n=16). Plasma PlGF level in CAD group was significantly higher than that in Non-CAD group and control group [(10.70 ± 0.49) ng/L vs (4.53 ± 0.64) ng/L vs (3.64 ± 0.36) ng/L, P lt; 0.001)], and there was no significant difference between the non-CAD group and control group (P gt; 0.05). A significant positive correlation was found between Gensini coronary score and plasma PlGF level (r=0.918, P lt; 0.01). Moreover, patients with cardiovascular events had a higher PlGF level than those without cardiovascular events after PTCA and stent implantation [(13.98 ± 3.39) ng/L vs (7.25 ± 2.96) ng/L, P lt; 0.01)]. Conclusion PlGF level has diagnostic value in patients with acute chest pain. The measurement of plasma PlGF might be helpful for early diagnosis of coronary artery disease. Patients with higher plasma PlGF level may have more severe coronary lesion. PlGF may be one of predictors for cardiovascular events after PCI.

  • Effectiveness and Safety of Coronary Artery Bypass Grafting for Unprotected Left Main Coronary Artery: A Systematic Review

    Objective To systematically review the effectiveness and safety of coronary artery bypass grafting (CABG) versus percutaneous coronary stent implantation (PCI) in the treatment of patients with unprotected left main coronary artery disease (ULMCA). Methods Databases including The Cochrane Library (Issue 2, 2012), PubMed, EMbase, CBM, CNKI, WanFang Data and VIP were electronically searched from inception to September 2012 for randomized controlled trials on the effectiveness and safety of coronary artery bypass grafting (CABG) versus percutaneous coronary stent implantation (PCI) for ULMCA; References of the included studies were also retrieved. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of the included studies. Then, meta-analysis was performed using RevMan 5.0. Results Four studies were included involving 1 611 cases, of which, 802 cases are in the CABG group, while 809 cases were in the PCI group. The results of meta-analysis showed that: comparing with PCI, CABG significantly reduced the postoperative repeat revascularization rate (OR=0.45, 95%CI 0.31 to 0.66, Plt;0.000 1), but there was no significant difference between the two groups in reducing the myocardial infarction incidence (OR=1.28, 95%CI 0.47 to 3.48, P=0.63), mortality rate (OR=1.36, 95%CI 0.80 to 2.34, P=0.26), and the incidence of major adverse cardio-cerebral vascular events (OR=0.92, 95%CI 0.66 to 1.28, P=0.61). Conclusion This study indicates that CABG is superior to PCI in reducing postoperative rate of target vessel revascularization. But CABG and PCI are alike in reducing myocardial infarction incidence, mortality rate, and the incidence of major adverse cardio-cerebral vascular events. Due to the limited quantity and quality of the included studies, the above conclusion needs to be verified by more high quality RCTs.

  • Drug Therapy for No-reflow Phenomenon Following Coronary Stent Implantation: A Systemic Review

    Objectives To evaluate the clinical efficacy and safety of coronary artery drug injection for slow flow/no-reflow phenomenon after coronary stent implantation. Methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, Issue 2, 2009), PubMed, EMbase, CBM, CNKI, VIP, and WanFang databases from their inception to April 2009. Two reviewers independently evaluated the quality of the included studies and extracted the data. Meta-analyses were performed by RevMan 5.0 software. Results Eight randomized controlled trials (RCTs) involving 593 patients were included. The results of meta-analyses showed that urokinase, adenosine, and anisodamine could significantly improve the thrombolysis in myocardial infartion (TIMI) flow. In addition, anisodamine could improve the coronary blood pressure. Urokinase significantly reduced the incidence of malignant ventricular arrhythmias and non-fatal of heart failure during hospitalization, but it could not change the mortality and the incidence of unstable angina, recurrence of myocardial infarction, and ischemic target revascularization. Conclusion Evidence shows that anisodamine, urokinase, urapidil and adenosine can improve TIMI flow and improve myocardial perfusion on the no-reflow patients post coronary stent implantation and urokinase can significantly reduce the incidence of main adverse cardiovascular events. Their clinical application is worthy to be advocated.

    ObjectiveTo evaluate safety and effectiveness of stent placement and emergency surgery in treatment of proximal colon cancer obstruction.MethodsThe PubMed, Embase, Cochrane Library, ClinicalTrials, CNKI, CBM, Wanfang Data, etc. were searched comprehensively. The literatures of Chinese and English randomized controlled trial and retrospective comparative study of stent placement and emergency surgery for the proximal colon cancer obstruction were retrieved. The RevMan 5.3 and Stata 12.0 softwares were used. The meta-analysis was made on the safety and effectiveness of these two treatments.ResultsA total of 9 literatures involving 636 patients were included, all of them were the retrospective studies, 4 of them only reported the clinical success rate and technical success rate. The technical success rate of stent placement was 0.94 [95% CI (0.91, 0.96)]. The clinical success rate was 0.90 [95% CI (0.87, 0.93)]. Compared with the emergency surgery group, the total complication rate and the temporary stoma rate were lower [OR=0.32, 95% CI (0.11, 0.94), P=0.04; OR=0.18, 95% CI (0.05, 0.65), P=0.009] and the hospital stay was shorter [MD=–2.97, 95% CI (–4.52, –1.41), P=0.000 2] in the stent placement group. The perioperative mortality rate, laparoscopic surgery rate, 5-year disease-free survival rate, and 5-year overall survival rate had no significant differences between these two groups (P>0.05).ConclusionCompared with emergency surgery, endoscopic stent placement for treatment of proximal colon cancer obstruction has a lower incidence of complications, temporary colostomy rate, shorter hospital stay, and it has no significant differences in mortality, laparoscopic surgery rate, and survival rate.

  • Long-term Effect of Coronary Artery Bypass Grafting for Coronary Multivessel Lesions: A Meta-analysis

    ObjectiveTo systematically review the long-term efficacy of coronary artery bypass grafting (CABG) versus drug-eluting stent implantation (DES-PCI) for patients with multivessel coronary artery disease. MethodsWe searched The Cochrane Library (Issue 2, 2015), PubMed, EMbase, CBM, CNKI, WanFang Data and VIP to collect randomized controlled trials (RCTs) about CABG versus DES-PCI for patients with coronary multivessel disease from the inception to October 2015. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then meta-analysis was performed by using RevMan 5.2 software. ResultsA total of seven RCTs, involving 5 723 patients were included. The results of meta-analysis showed that: compared with the DES-PCI group, the CABG group had lower 1-year incidence of target vessel revascularization (OR=0.39, 95%CI 0.31 to 0.48, P<0.000 01), 5-year mortality (OR=0.78, 95%CI 0.65 to 0.94, P=0.008), and 5-year incidence of myocardial infarction (OR=0.46, 95%CI 0.37 to 0.58, P<0.000 01). However, 1-year, 2-year and 5-year incidences of stroke in the CABG group were significantly higher than that in the DES-PCI group (all P values <0.05). ConclusionThe available evidence suggests that CABG is superior to DES-PCI for patients with multivessel coronary artery disease in long-term effects, but CABG could increase the incidence of stroke. Due to the quantity and quality of the included studies, the above conclusions still need to be verified by more high-quality RCTs.

  • Progress and prospect of reducing jaundice tretment in elderly patients with malignant obstructive jaundice

    ObjectiveTo summarize the various treatment methods for reducing jaundice in the elderly patients with malignant obstructive jaundice (MOJ), and provide reference for the treatment of elderly MOJ.MethodUsing “malignant obstructive jaundice” as the Chinese keyword and the English keyword, a computer search of the literatures on the treatment of elderly MOJ patients was conducted and reviewed.ResultsThe treatment methods of reducing jaundice in elderly MOJ included radical surgery, cholangiojejunostomy, endoscopic ultrasound-guided biliary drainage, endoscopic biliary stent implantation, percutaneous transhepatic biliary drainage and stent implantation. Radical surgery was the most effective, but it was traumatic and had many complications for elderly patients. Cholangiojejunostomy was effective and suitable for elderly patients who cannot tolerate major surgery. Endoscopic ultrasound-guided biliary drainage was less traumatic to elderly patients, but technical difficulty. Endoscopic biliary stent implantation was currently the first-line choice for the treatment of elderly patients with advanced MOJ. Percutaneous transhepatic biliary drainage and stent implantation were suitable for elderly and frail patients with high obstruction.ConclusionThe treatment of elderly MOJ needs to be individualized and regionalized, and appropriate treatment methods should be selected according to the patient’s condition and the medical level of the medical center.

  • Correlation between Serum Bilirubin and Recurrent Coronary Events in Patients after Coronary Artery Stent Implantation

    ObjectiveTo investigate the factors related to recurrent coronary events in patients after coronary artery stent implantation. MethodsWe retrospectively studied the patients performing coronary angiography (CAG) who were admitted to the Department of Cardiology of the Second Affiliated Hospital of Guangzhou Medical University between January 2012 and June 2013. All of the enrolled patients had received CAG in our hospital, with complete coronary angiogram and clinical data. The patients were divided into two groups according to the coronary angiogram and clinical data: coronary event group and non-coronary event group. SPSS 16.0 software was employed for statistical analysis, and multivariate analysis was performed using binary logistic regression model to analyze the risk factors. ResultsA total of 115 patients were included, of which 50 patients had recurrent coronary events. Both the serum total bilirubin and unconjugated bilirubin in patients with coronary events were significantly lower compared with the patients without coronary events at baseline and at the time of CAG reexamination (P < 0.05 or P < 0.01). The serum total bilirubin at baseline and the serum total bilirubin and unconjugated bilirubin at the time of CAG reexamination were significantly lower in patients with revasculization due to the progression of coronary artery lesions compared with the patients without coronary events (P < 0.05 or P < 0.01). The serum unconjugated bilirubin in patients with in-stent restenosis were significantly lower compared with the patients without coronary events at baseline and at the time of CAG reexamination (P < 0.05). The results of logistic regression analysis showed that multi-vessel coronary artery disease (two-vessel coronary artery disease: OR=10.094, 95%CI 2.498 to 40.798, P=0.001; three-vessel coronary artery disease: OR=16.047, 95%CI 4.121 to 62.481, P=0.000) and low serum unconjugated bilirubin (OR=0.873, 95%CI 0.773 to 0.987, P=0.03) were independent risk factors of recurrent coronary events. ConclusionMulti-vessel coronary artery disease and low serum unconjugated bilirubin are independent risk factors of recurrent coronary events in patients after coronary artery stent implantation.
