Objective To evaluate the influences of myocardial injury markers on the short-term and long-term mortality after coronary artery bypass grafting (CABG), so as to provide valuable references for clinical prognosis assessment. Methods Literature was electronically searched in CBM, PubMed, OVID, EMbase and CNKI from the date of their establishment to August 2011, meanwhile the manual searches were also performed to systemize the papers. According to the Cochrane Handbook for systematic reviews, the studies were screened by two reviewers independently, the quality of the included studies was evaluated, the data were extracted, and meta-analysis was conducted using RevMan5.0 software. Results A total of 10 observational studies including creatine kinase-myocardial band (CK-MB) and cardiac troponin I (cTnI), and the patients involved were 10 793 totally. Results of meta-analysis showed that the increasing release of CK-MB was associated with an increasing short-term mortality risk of both on-pump (RR=2.88, 95%CI 1.94 to 4.28, Plt;0.000 01) and off-pump group (RR=3.64, 95%CI 1.07 to 12.42), P=0.04). Also the increasing release of CK-MB was associated with an increasing long-term mortality risk of both on-pump (RR=2.55, 95%CI 1.91 to 3.40, Plt;0.000 01) and off-pump group (RR=3.36, 95%CI1.46 to 7.72, P=0.004). The increasing release of cTnI was also associated with an increasing risk of both short-term mortality (RR=6.45, 95%CI 2.50 to 16.66, Plt;0.1) and long-term mortality (RR=4.18, 95%CI 2.78 to 6.28, Plt;0.1). Conclusion The evidence shows that the increasing release of both CK-MB and cTnI is associated with an increasing risk of the short-term and long-term mortality.
ObjectiveTo analyze the influencing and prognostic factors for in-hospital death of creatine kinase-MB after cardiac surgery for congenital heart disease in pediatric. MethodsClinical data of 708 children with body weight less than 15 kg who underwent cardiac surgery at Fu Wai Hospital between January 2012 and December 2013 were retrospectively analyzed. There were 269 males (38.0%) and 439 females (62.0%). The postoperative maximum CK-MB was calculated for analysis and patients were devided into three groups:a group A (CK-MB≤25 IU/L), a group B (25 IU/L < CK-MB≤125 IU/L) and a group C (CK-MB > 125 IU/L). ResultsPostoperative CK-MB level was independently associated with cyanotic congenital heart disease (P=0.002), the aorta cross clamp (P=0.030), the cardiopulmonary bypass time (P=0.002), the cross clamp time (P=0.016), the re-establish of bypass (P < 0.001), deep hypothermic circulatory arrest (P=0.024). There was statistical difference in mortality between the 3 groups (P < 0.001). The receiver operating characteristic curve showed that CK-MB has predictive value for in-hospital death (P < 0.001) and the cutoff value is 168.5 IU/L, with a sensitivity of 54.2%, specificity of 90.8%, positive predictive value of 17.3% and negative predictive value of 98.4%. CK-MB level above 168.5 IU/L was an independent risk factor for in-hospital death (OR=6.364, P < 0.001). ConclusionElevation of CK-MB after cardiac surgery is independently influenced by several variables. Pediatric with major CK-MB elevation has high risk of in-hospital death.
Objective To investigate the dynamic expression and clinical significance of myoglobin, creatine kinase and inflammatory mediators in the serum of patients with multiple trauma. Methods From May 2013 to March 2015, 56 patients with multiple trauma admitted in EICU were recruited in the study. According to the injury severity, 56 patients were divided into a mild trauma group, a medium trauma group and a severe trauma group. The subjects were further divided into a MODS group and a non-MODS group based on multiple organ dysfunction syndrome (MODS) criteria. Twenty healthy adults undergoing physical examination were recruited as control. Serum myoglobin, creatine kinase, IL-6 and TNF-α levels were measured in the multiple trauma patients (1st day, 3rd day, 7th day and 14th day) and the controls. Results Compared with the controls, the serum levels of myoglobin, creatine kinase, IL-6 and TNF-α in the patients with multiple trauma increased significantly from 1st to 14th day after injury (allP＜0.05). Serum myoglobin, creatine kinase, IL-6 and TNF-α levels on 3rd day after injury reached the peak, then decreased gradually in the mild, medium, and severe trauma groups, among which the changes of serum myoglobin, creatine kinase, IL-6 and TNF-α levels were significant on 3rd day compared with other timepoints (allP＜0.05). On 1st day after injury, serum levels ofmyoglobin, creatine kinase, IL-6 and TNF-α also differed significantly between the MODS group and non-MODS group (allP＜0.05). The AUCs of myoglobin, IL-6 and TNF-α for predicting MODS were 0.527-0.817, 0.641-0.890, and 0.197-0.544, respectively. Conclusions The dynamic changes of serum myoglobin, creatine kinase, IL-6 and TNF-α in patients with multiple trauma are correlated well with the injury severity and prognosis. Serum myoglobin, IL-6 and TNF-α levels may be good markers to predict secondary MODS in multiple trauma patients.
