Objective To identify the relationship between preoperative left ventricular dysfunction and perioperative risk factors in coronary artery bypass grafting (CABG). Methods The clinical data of 192 patients who underwent CABG from November 2015 to October 2016 were analyzed retrospectively. The patients were divided into three groups by preoperative left ventricular ejection fraction (LVEF) in echocardiography: a serious left ventricular dysfunction group (LVEF≤35%, 23 patients, 15 males and 8 females at age of 63.91±5.36 years), a moderate left ventricular dysfunction group (35%<LVEF<50%, 24 patients, 20 males and 4 females at age of 66.29±6.03 years) and a normal left ventricular function group (LVEF≥50%, 145 patients, 86 males and 59 females at age of 66.60±6.41 years). Results The overall mortality was 4.16% (8/192), 17.39% (4/23) in patients with LVEF≤35% and 2.76% (4/145) in those with LVEF≥50%. Preoperative LVEF≤35%, hypoxia, assisted circulation, acute kidney injury (AKI) and postoperative continuous renal replacement therapy (CRRT) were risk factors of perioperative mortality in coronary artery surgery. LVEF≤35% and CRRT were independent preditors of mortality. There were significant differences in mortality and postoperative complications between the serious left ventricular dysfunction group and other two groups. Conclusion Postoperative mortality and complications are obviously serious in the patients with LVEF≤35%. We should pay more attention to preoperative risk factors. Postoperative individual manipulation, intra-aortic balloon pump and CRRT can enhance survival of those patients.

目的探讨脾静脉高压的临床特征及诊断依据。方法 回顾性分析6例脾静脉高压病例的临床症状、体征、影像学检查及术中发现等资料。结果 临床症状主要表现为呕血和便血； CT扫描3例脾静脉狭窄，3例脾静脉显示不清； 术中测定门静脉压力，切脾前左侧为2.94±0.2 kPa(35.0±2.1 cmH2O)，高于右侧的1.96±0.2 kPa(20.0±2.3 cmH2O)，切脾后左侧为2.06±0.1 kPa(21.0±1.3 cmH2O)，右侧为1.76±0.1 kPa(18.0±1.4 cmH2O)，二者无明显差异。术中探查脾静脉，5例脾静脉栓塞，1例狭窄。结论 术前CT增强扫描，术中测定左右半门静脉压力以及术中发现脾静脉栓塞或狭窄，可以诊断脾静脉高压。
ObjectiveTo investigate the risk factors of death in patients undergoing continuous renal replacement therapy (CRRT) after cardiac surgery. MethodsWe retrospectively analyzed records of 66 adult patients without history of chronic renal failure suffering acute kidney injury (AKI) following cardiac surgery and undergoing CRRT in our hospital between July 2007 and June 2014. There were 38 males and 28 females with mean age of 59.11±12.62 years. They were divided into a survival group and a non-survival group according to prognosis at discharge. All perioperative data were collected and analyzed by univariate analysis and multivariate logistic regression analysis. ResultsIn sixty-six adult patients, eighteen patients survived with a mortality rate of 72.7%. Through univariate analysis and multivariate logistic regression, risk factors of death in the post-operative AKI patients requiring CRRT included hypotension on postoperative day 1 (B=2.897, OR=18.127, P=0.001), duration of oliguria until hemofiltration (B=0.168, OR=1.183, P=0.024), and blood platelet on postoperative day 1 (B=-0.026, OR=0.974, P=0.001). ConclusionHypotension on postoperative day 1 (POD1) is the predominant risk factor of death in patients requiring CRRT after cardiac surgery, while blood platelet on POD1 is a protective factor. If CRRT is required, the sooner the better.
ObjectiveTo systematically evaluate the efficacy and safety of radiofrequency ablation versus amiodarone in the treatment of atrial fibrillation, so as to provide reference for the chosen of clinical treatment options. MethodsWe searched PubMed, The Cochrane Library (Issue 10, 2014), CNKI, VIP and WanFang data from inception to October 2014 to collect randomized controlled trials (RCTs) comparing radiofrequency ablation versus amiodarone for atrial fibrillation. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.3 software. ResultsA total of 4 RCTs involving 511 atrial fibrillation patients were included. The results of meta-analysis showed that:compared with amiodarone, radiofrequency ablation could reduce the risk of atrial fibrillation recurrence (RR=0.35, 95%CI 0.22 to 0.55, P<0.000 01). There was no significant difference in all-cause mortality (RR=0.97, 95%CI 0.17 to 5.61, P=0.97) between both groups. The incidence of adverse events in the radiofrequency ablation group was 7.7%, and was lower than 12.7% of the amiodarone group, but there was no significant difference between the two groups. ConclusionCurrent evidence shows that, compared with amiodarona, radiofrequency ablation is related to lower recurrence rate and higher efficacy, but there is no difference in the safety between the two interventions. However, due to the limited quality and quantity of included studies, higher quality studies are needed to verify the above conclusion.
