Objective:To evaluate the effect of ulinastatin on the postoperative pulmonary complications (PPCs) in the patients undergoing off-pump coronary artery bypass grafting (OPCABG).Methods:Medical records from patients scheduled for elective OPCABG from September 2021 to August 2023 were retrospectively collected. The patients were divided into ulinastatin and control groups based on the intraoperative use of ulinastatin. Confounding factors were adjusted using propensity score matching and an extended Cox proportional hazards model. The primary outcome was the development of PPCs within 30 days after surgery, and secondary outcomes included length of stay in intensive care unit, length of hospital stay and occurrence of other adverse events.Results:A total of 1 532 patients were included in this cohort study, and 585 cases (38.2%) experienced PPCs. Compared with control group, the incidence of PPCs was significantly decreased (before matching: 42.7% vs. 35.2%, P=0.004; after matching: 42.2% vs. 35.6%, P=0.033), the incidence of acute kidney injury was decreased and no significant differences were found in the length of stay in intensive care unit, length of hospital stay and incidence of other adverse events in ulinastatin group ( P>0.05). In the extended Cox proportional hazard model before and after adjustment for confounding factors, the risk of PPCs was significantly reduced after the use of ulinastatin ( HR value before adjustment was 0.81, 95% confidence interval [ CI] 0.67-0.99, P=0.004; the HR value after adjustment was 0.79, 95% CI 0.65-0.96, P=0.022). The risk of PPCs was significantly decreased in patients aged >65 yr and at high risk of PPCs after using ulinastatin ( HR=0.667, 95% CI 0.542-0.821, P<0.001; hR value was 0.641, 95% CI 0.516-0.812, P<0.001). Conclusions:The intraoperative use of ulinastatin is helpful in decreasing the risk of PPCs in patients undergoing OPCABG.

Objective:To explore the current status of barriers to participation in phaseⅡcoronary artery bypass grafting (CABG) patients and the factors influencing them, and to provide new ideas for reducing barriers to participation in rehabilitation and improving the participation rate in cardiac rehabilitation.Methods:For this study, a cross-sectional survey research method was utilized. The study included 334 patients who underwent CABG and were admitted to the Second Hospital of Hebei Medical University between June 2022 and May 2023. These patients were selected using the convenience sampling method. A General Information Questionnaire, the Cardiac Rehabilitation Barriers Scale (CRBS-C/M), and a Questionnaire on the Knowledge of Information Related to Cardiac Rehabilitation were used to conduct the survey. Multiple linear regression was used to analyze the independent influencing factors on barriers to participation in phase Ⅱ cardiac rehabilitation in post-CABG patients.Results:Out of 334 patients, 248 were males and 86 were females with age (54.74 ± 7.61) years old. The total average score of CRBS-C/M in patients after CABG surgery was 3.20 ± 0.43, with the highest external logistic factors score of 3.42 ± 0.58. The knowledge status score of information related to cardiac rehabilitation was 42.11 ± 7.94. Multiple linear regression analysis revealed that the following factors independently influenced post-CABG patients′ barriers to participating in phaseⅡcardiac rehabilitation: marital status, whether or not they had completed phase I cardiac rehabilitation,number of other comorbidities, knowledge of cardiac rehabilitation information. All of these differences were statistically significant ( t values were -4.87-3.35, all P<0.05). Conclusions:The barriers to participation in phase Ⅱ cardiac rehabilitation in post-CABG patients are at an intermediate to high level, and healthcare professionals should emphasize the assessment of barrier factors in these patients, and target the development and implementation of phase Ⅱ cardiac rehabilitation in terms of the influencing factors.

La cirugía de revascularización coronaria (CABG) es el estándar de tratamiento para la revascularización de la enfermedad de la arteria coronaria izquierda y/o de tres vasos. La cirugía coronaria sin bomba (OPCAB) evita el uso de derivación cardiopulmonar y puede mejorar los resultados a largo plazo al reducir las tasas de lesión miocárdica perioperatoria, accidente cerebrovascular (ACV), deterioro neurocognitivo y mortalidad de causa cardiaca. En la actualidad, se han llevado a cabo diversos ensayos clínicos desde la popularización del OPCAB en la década de los 90. Sin embargo, hasta el momento no se ha demostrado ningún beneficio del OPCAB en comparación con la cirugía tradicional a pesar de las reducciones favorables a corto plazo en los requerimientos de transfusión y otras complicaciones postoperatorias. Además, OPCAB se asocia con una revascularización miocárdica menos eficaz y no previene por completo las complicaciones tradicionalmente asociadas con la circulación extracorpórea (CEC). Este artículo revisa la evidencia actual de OPCAB en comparación con CABG tradicional en cuanto a los resultados clínicos a corto y largo plazo. Se analizan los resultados de la cirugía coronaria sin circulación extracorpórea (CEC) , comparándola con la cirugía convencional (con CEC). La revascularización coronaria sin CEC presenta resultados similares a la convencional, siempre que se cumplan determinadas condiciones en la selección de los pacientes. Una de ellas, muy importante, es la mayor experiencia del cirujano con el procedimiento.
The results of coronary artery revascularization performed without extracorporeal circulation (off pump) are compared to those of the traditional ("on pump") procedure. Compliance with selective conditions are required to obtain similar results. The most important being the experience of the surgeon performing the off pump procedure.

Background: Quantification of urinary tissue inhibitor of metalloproteinase?2 (TIMP?2) and insulin?like growth factor binding protein (IFGBP?7), which is commercially known as NephroCheck�(NC) test have been suggested as promising tools for the early detection of acute kidney injury (AKI) after cardiac surgery involving cardio?pulmonary bypass (CPB). Objectives: The aim of the present study was to test the hypothesis that single value of postoperative NC test performed at 4 hours after surgery can predict AKI in off?pump coronary artery bypass grafting (OPCABG) surgery. Setting and Design: This prospective single?center study was conducted at the tertiary cardiac center in India from December 2017 to November 2018. Methods: Ninety adult patients of both sex undergoing elective OPCABG were included. Anesthesia was standardized to all patients. Urine samples were collected preoperatively and at 4 hours after surgery for NC test. Urine output, serum creatinine, estimated glomerular filtration rate (eGFR) were also measured. AKI staging was based on kidney disease improving global outcomes (KDIGO) guidelines. Statistical Analysis: To assess the predictability of NC test for the primary endpoint, area under the receiver operating characteristic curve (ROC), was calculated. Results: Thirteen patients developed AKI in the study cohort (14.4%) out of which 7 patients (7.8%) developed stage 2/3 AKI and the remaining stage 1 AKI. Baseline renal parameters were similar between AKI and non?AKI group. The area under curve (AUC) of NC test at 4 hours after surgery was 0.60 [95% confidence interval (CI): 0.42?0.77]. Postoperative NC test performed at 4 hours after surgery did not predict AKI in this study population (P = 0.24). There were no significant differences in duration of mechanical ventilation, length of intensive care stay and hospital stay between the two groups (P > 0.05). Conclusion: NephroCheck� test performed at 4 hours after surgery did not identify patients at risk for developing AKI following OPCABG surgery

Coronary Artery Bypass Grafting (CABG) Surgery is considered the standard treatment for revascularization in Coronary Artery Disease. The Off-Pump Coronary Artery Bypass Graft (OPCAB) which evades the use of Cardiopulmonary Bypass (CPB) became a popular CABG procedure, due to the adverse effect of CPB. Hypothetically, OPCAB may improve the rates of perioperative Myocardial Injury, Neurocognitive Impairment, Stroke and Mortality. However, some studies showed no superior outcomes for OPCAB compared to on-pump CABG. This study aims to evaluate the short-term and long-term outcomes of OPCAB versus On-Pump CABG. The results showed that OPCAB is probably a safe procedure for patients, especially for those with high-risk conditions. OPCAB procedure showed superior short-term outcomes in terms of Myocardial Infarction, Systemic Inflammatory Response, Postoperative Cognitive Dysfunction, Renal Failure, Stroke, Pulmonary Complication, Postoperative Transfusion, Hospital stay length and infection than On-pump CABG. However, regarding long-term outcomes, Off-Pump CABG had a higher rate of incomplete revascularization and repeat revascularization and a higher risk of long-term mortality as well as lower graft patency. Furthermore, the result showed that the higher experience of the surgeons in OPCAB improves the outcome of the Surgery.

BACKGROUND: Long-term outcomes of Off-Pump Coronary Artery Bypass Grafting (OPCAB) as an alternative to the traditional Coronary Artery Bypass Grafting (CABG) technique with cardiopulmonary bypass (CPB) are not well defined. AIM: To compare 10-year survival of isolated OPCAB versus CABG with CPB. MATERIAL AND METHODS: Analysis of information obtained from databases, clinical records and surgical protocols of patients treated with isolated CABG between January 2006 and November 2008 at a Regional Hospital. Of 658 isolated CABG, 192 (29.2%) were OPCAB and 466 (79.9%) CPB. Propensity Score Matching (PSM) was performed to compare both groups. After PSM, two groups of 192 cases were obtained. Mortality data was obtained from the Chilean public identification service. Ten-year survival was calculated and compared with Kaplan-Meier and log-rank methods. RESULTS: Follow-up data was obtained in all cases. No statistically significant differences were found when comparing 10-year survival between OPCAB versus CPB (78.6% and 80.2% respectively, p 0.720). There was also no statistical difference in cardiovascular death free survival (90.1% with CPB versus 89.1% OPCAB, p 0.737). Survival was comparable when analyzing subgroups with diabetes mellitus, left ventricular dysfunction or chronic kidney disease, among others. CONCLUSIONS: In our series, OPBAB has a comparable 10-year survival with CABG with CPB.

Objective:To evaluate the dose-response relationship of remimazolam for loss of consciousness during anesthesia induction in the patients undergoing coronary artery bypass grafting (CABG).Methods:American Society of Anesthesiologists Physical Status classification Ⅲ or Ⅳpatients, aged 55-64 yr, with body mass index of 21-26 kg/m 2, scheduled for elective CABG under general anesthesia, were included in this study.The trial was conducted using the modified Dixon′s up-and-down method. The initial dose of remimazolam was 0.225 mg/kg, each time the concentration increased/decreased by 0.025 mg/kg in the next patient depending on whether or not the patients lost consciousness. Criteria for loss of consciousness was considered as the modified vigilance sedation score≤1 within 3 min after remimazolam administration. The 50% effective dose (ED 50), 95% effective dose (ED 95) and their 95% confidence interval ( CI) was analyzed by probit probability analysis method. Results:The ED 50 of remimazolam for loss of consciousness during anesthesia induction was 0.175 mg/kg, 95% CI was 0.163-0.185 mg/kg, ED 95 was 0.211 mg/kg, and 95% CI was 0.197-0.255 mg/kg. Conclusions:The ED 50 and ED 95 of remimazolam were 0.175 and 0.211 mg/kg respectively when used for loss of consciousness during anesthesia induction in the patients undergoing CABG.

Objective:Of all spontaneous bleeding complications in patients with acute ST-elevation myocardial infarction (STEMI), upper gastrointestinal bleeding (UGIB) is the most common and of specific interest, because it can be prevented by several prophylactic measures. The purpose of this study was to investigate the in-hospital incidence, associated outcomes, and predictors of UGIB after STEMI.Methods:In this retrospective study, we analyzed the records of 2 791 patients with acute STEMI admitted to Beijing Anzhen Hospital Affiliated to Capital Medical University between January 2018 and January 2022. The patients were divided into the UGIB group ( n=61) and non-UGIB group ( n=2 730) according to the presence or absence of upper gastrointestinal hemorrhage, respectively. Baseline clinical conditions, coronary lesions, in-hospital deaths, and in-hospital adverse events were compared between the two groups. Logistic regression analysis was also performed for risk factors that could lead to UGIB. Results:The in-hospital incidence of UGIB after STEMI was 2.2% (61/2 791). Hospital stay was significantly longer in the UGIB group [8(6, 12) days vs. 5 (4, 7) days, Z=3.28, P<0.001] and in-hospital mortality was significantly higher in the UGIB group than in the non-UGIB group (9.8% vs. 0.8%, χ2=0.63, P=0.001). Patients with UGIB were significantly older than those without UGIB (63±11 years vs. 58±11 years, t=-3.75, P<0.001). The serum creatinine level of UGIB patients was significantly higher than that of non-UGIB patients [(80(62, 98) mmol/L vs. 73(64, 84) mmol/L, Z=1.68, P=0.007], the red blood cell count of UGIB patients was significantly lower than that of non-UGIB patients [4.1(3.8, 4.6)×10 12/L vs. 4.6(4.2, 4.9)×10 12/L, Z=2.61, P<0.001], and the hemoglobin concentration of UGIB patients was significantly lower than that of non-UGIB patients [129(109, 141) g/L vs. 141(130, 152) g/L, Z=2.52, P<0.001]. Brain natriuretic peptide levels were significantly higher in UGIB patients than in non-UGIB patients [331(165, 644) ng/L vs. 181(89, 333) ng/L, Z=2.42, P<0.001]. Logistic regression analysis showed that age ( OR=1.045, 95% CI 1.009-1.082, P=0.013); hemoglobin ( OR=1.594, 95% CI 1.150-2.210, P=0.005); hematocrit ( OR=0.181, 95% CI 0.060-0.546, P=0.002); and mean hemoglobin concentration ( OR=0.845, 95% CI 0.752-0.951, P=0.005) were independent risk factors for UGIB in patients with STEMI. Logistic regression analysis of risk factors for in-hospital death revealed that concurrent UGIB was an independent risk factor for in-hospital death in patients with STEMI ( OR=2.954, 95% CI 0.635-13.751, P=0.024). Conclusions:The incidence of in-hospital UGIB in STEMI patients was 2.2%, and the in-hospital mortality rate of STEMI complicated with UGIB increased to 9.8%. Concurrent UGIB was an independent risk factor for in-hospital death in patients with STEMI. The most important predictors of in-hospital UGIB in patients with STEMI were age, hemoglobin, hematocrit, and mean hemoglobin concentration.

@#Objective To study the relationship between preoperative heart rate variability (HRV) and postoperative atrial fibrillation (POAF) after off-pump coronary artery bypass grafting (OPCAB). Methods A retrospective analysis was performed on the clinical data of 290 patients who were admitted to the Department of Cardiovascular Surgery, General Hospital of Northern Theater Command from May to September 2020 and received OPCAB. There were 217 males and 73 females aged 36-80 years. According to the incidence of POAF, the patients were divided into two groups: a non-atrial fibrillation group (208 patients) and an atrial fibrillation group (82 patients). The time domain and frequency domain factors of mean HRV 7 days before operation were calculated: standard deviation of all normal-to-normal intervals (SDNN), root mean square of successive differences, percentage difference between adjacent normal-to-normal intervals that were greater than 50 ms, low frequency power (LF), high frequency power (HF), LF/HF. Results The HRV value of patients without POAF was significantly lower than that of patients with POAF (P<0.05). The median SDNN of the two groups were 78.90 ms and 91.55 ms, respectively. Age (OR=3.630, 95%CI 2.015-6.542, P<0.001), left atrial diameter (OR=1.074, 95%CI 1.000-1.155, P=0.046), and SDNN (OR=1.017, 95%CI 1.002-1.032, P=0.024) were independently associated with the risk of POPAF after OPCAB. Conclusion SDNN may be an independent predictor of POAF after OPCAB.

A 70-year-old woman diagnosed with angina pectoris was scheduled to undergo off-pump coronary artery bypass grafting (OPCAB) using the left internal thoracic artery and the saphenous vein (SVG). We performed a proximal anastomosis of the SVG to the ascending aorta using a clampless proximal anastomotic device. When this device was removed from the ascending aorta after completion of the SVG proximal anastomosis, we noticed the extensive appearance of an ascending aortic adventitial hematoma. Transesophageal echocardiography revealed a flap in the ascending aorta, which was diagnosed as an iatrogenic aortic dissection. The decision was made to immediately perform an additional aortic replacement. There was an intimal tear consistent with the device insertion site, which was identified as the site for the development of aortic dissection. After performing an ascending aortic replacement, coronary artery bypass grafting was performed. Her postoperative course was uneventful, and enhanced CT on postoperative day 12 showed aortic dissection up to the level of the abdominal aorta, but the false lumen was completely thrombosed. Iatrogenic aortic dissection caused by proximal anastomotic device during OPCAB is a very rare but serious complication, and early intraoperative diagnosis and prompt additional surgical treatment were considered necessary to save the patient's life.

Man in his 70s, who had suffered from idiopathic thrombocytopenic purpura (ITP), was admitted to our hospital with chest pain at rest. Coronary angiography revealed obstruction of the right coronary artery and triple vessel disease. Because a bleeding tendency was expected during coronary artery bypass grafting, we performed percutaneous coronary intervention to the culprit lesion first, and then intravenous immunoglobulin and high dose dexamethasone were tried. His platelet count rose from 49,000 to 103,000/mm3, so we performed coronary artery bypass grafting. The patient had no postoperative hemorrhagic complications. We believe that high dose dexamethasone therapy is useful for patients with ITP who need surgery immediately.

Objective:To observe the different administration methods of methoxamine on the body temperature protection of patients undergoing off-pump coronary artery bypass grafting (OPCABG).Methods:The clinical data of 278 patients underwent OPCABG from January 2019 to December 2021 in Jinzhou Central Hospital were retrospectively analyzed, and the patients were used the methoxamine during the operation. Among them, 157 cases were given methoxamine by continuous intravenous infusion (continuous intravenous infusion group), and 121 cases were given methoxamine by fractional intravenous infusion in stages (fractional intravenous infusion group). The changes of mean arterial pressure (MAP) and heart rate during operation were recorded, and the fluctuation rate of MAP was calculated. The dosage of methoxamine, use time of variable temperature blanket, time from the end of operation to waking up and occurrence of adverse reactions such as hypothermia, rigors, coagulation disorders and renal insufficiency were recorded.Results:During anesthesia, the fluctuation rate of MAP in continuous intravenous infusion group was significantly lower than that in fractional intravenous infusion group: (16.62 ± 3.17)% vs. (23.53±3.69)%, and there was statistical difference ( P<0.05). The MAP and heart rate of continuous intravenous infusion group were more stable at each time point than that of fractional intravenous infusion group. The use time of variable temperature blanket, and incidences of hypothermia, rigors in continuous intravenous infusion group were significantly lower than those in fractional intravenous infusion group: (86.17 ± 19.66) min vs. (146.72 ± 29.37) min, 2.55% (4/157) vs. 9.92% (12/121) and 1.91% (3/157) vs. 8.26% (10/121), and there was statistical difference ( P<0.01 or <0.05); there were no statistical differences in dosage of methoxamine, time from the end of operation to waking up and incidence of coagulation disorders between two groups ( P>0.05); Renal insufficiency did not occur in both groups. Conclusions:Continuous intravenous pumping of methoxamine can obviously reduce the heat loss of human body, enhance the insulation effect of other insulation measures, and reduce the incidence of hypothermia in patients underwent OPCABG.

Objective:To investigate the difference of adverse events in patients with chronic obstructive pulmonary disease (COPD) who underwent on-pump coronary artery bypass grafting (ONCABG) and off-pump coronary artery bypass grafting (OPCABG).Methods:The clinical data of COPD patients undergoing CABG surgery admitted to Beijing Anzhen Hospital affiliated to Capital Medical University from January 2021 to December 2021 were retrospectively analyzed. According to whether they received cardiopulmonary bypass or not, they were divided into ONCABG group (64 cases) and OPCABG group (154 cases). The preoperative and postoperative clinical data were analyzed. The whole group was divided into 4 subgroups (ON1、ON2、OP1、OP2) according to whether receiving cardiopulmonary bypass or not and FEV160% as the cut-off point, to investigate the difference of postoperative adverse events.Results:A total of 218 patients were included, ranging in age from 45 to 76 years old, with a mean age of (63.81±7.72) years, including 149 males (68.35%). There was no significant difference in the incidence of postoperative adverse events between the ONCABG and OPCABG groups ( P>0.05). In subgroup analysis, the incidence of postoperative pulmonary infection (72.73% vs. 45.65%, P<0.05) and postoperative atrial fibrillation (59.09% vs. 32.61%, P<0.05) was higher in ON1 (FEV1≤60% ONCABG, 22 cases) group than in OP1 (FEV1≤60% OPCABG, 46 cases) group. Conclusion:The incidence of postoperative pulmonary infection and atrial fibrillation in COPD patients with FEV1≤60% was higher in ONCABG than in OPCABG.

@# Objective To analyze the efficacy of off-pump coronary artery bypass grafting (OPCABG) in elderly patients with coronary artery disease complicated with moderate ischemic mitral regurgitation. Methods The clinical data of patients aged≥70 years with coronary artery disease complicated with moderate mitral regurgitation, and undergoing OPCABG from January 2009 to January 2020 in Beijing Anzhen Hospital were retrospectively analyzed. The echocardiographic indicators of the patients were compared preoperatively, postoperatively before discharge and during the follow-up. Results Finally 239 patients were enrolled. There were 136 males and 103 females, aged 74.1±3.2 years. Before postoperative discharge, 49 (20.5%) patients had no mitral regurgitation, 144 (60.3%) mild regurgitation, 46 (19.2%) moderate regurgitation, and 0 severe regurgitation. The area of mitral regurgitation was significantly improved (2.5±1.8 cm2 vs. 5.6±1.0 cm2, P<0.001). There were 10 (4.2%) patients of hospital death, 23 (9.6%) of low cardiac output, 3 (1.3%) of myocardial infarction, and 8 (3.3%) of nervous system injury after operation. As a result, 208 (90.8%) patients were followed up and the mean follow-up time was 3.4 years (range 1-9 years). The cumulative survival rates at postoperative 2, 4, 6, and 8 years were 95.8%, 88.0%, 78.4%, and 73.1%, respectively. Postoperative follow-up showed significant improvements compared with those before surgery in the area of mitral regurgitation, left ventricular ejection fraction, left ventricular end-diastolic and left ventricular end-systolic diameters (all P<0.05). Duirng the follow-up, the major adverse cardiac and cerebrovascular events were all cause death in 22 (10.6%) patients, including cardiac death in 17 (8.2%) patients, myocardial infarction in 7 (3.4%) patients, heart failure in 24 (11.5%) patients, cerebrovascular events in 11 (5.3%) patients, re-hospitalization due to heart disease in 23 (11.1%) patients, and none of the patients with myocardial infarction were revascularized. Conclusion The mid- and long-term outcomes of OPCABG in the treatment for elderly patients with coronary artery disease complicated with moderate ischemic mitral regurgitation is good.

@#Objective To compare and analyze the postoperative quality of life in patients after minimally invasive coronary artery bypass grafting (MICABG) and conventional median thoracotomy off-pump coronary artery bypass grafting surgery (OPCABG). Methods From November 2015 to January 2018, 94 patients who underwent MICABG in the Peking University Third Hospital were included in the MICABG group. During the same period 441 patients who received OPCABG were included in the OPCABG group. The patients were matched by using propensity score matching method with a ratio of 1∶1. The quality of life was compared between two groups at 1 month, 6 months and 12 months after the surgery using SF-36 scale. Results A total of 82 patients were matched for each group. In the MICABG group, there were 66 males and 16 females with a mean age of 62.6±8.2 years. In the OPCABG group, there were 67 males and 15 females with a mean age of 63.2±13.2 years. One month after the operation, the physical health assessment (PCS) and mental health assessment (MCS) of the MICABG group were higher than those of the OPCABG group (50.3±10.6 points vs. 46.1±10.3 points, P=0.011; 59.5±9.3 points vs. 54.2±11.0 points, P=0.002). Scores of these following five dimensions: general health, physical functioning (PF), role-physical, social functioning (SF), role-emotion in the MICABG group were higher than those in the OPCABG group, while the score of body pain was inferior to that in the OPCABG group, and the differences were statistically significant (P<0.05). Six months after the surgery, the PCS and MCS of the two groups were not statistically different (80.0±13.1 points vs. 77.8±12.4 points, P=0.271; 81.6±13.5 points vs. 80.4±11.2 points, P=0.537). However, the scores of PF and SF in the MICABG group were still higher than those in the OPCABG group (P<0.05). Twelve months after the surgery, there was no statistical difference in the score of each dimension between the two groups (P>0.05). Conclusion The improvement of quality of life within 6 months after MICABG is better than that of OPCABG, and it is similar between the two groups at 12 months after the surgery, indicating that MICABG has a certain effect of improving the short-term quality of life after the surgery, and the long-term quality of life is comparable to conventional surgery.

@#Objective To analyze the risk factors for acute kidney injury (AKI) after off-pump coronary artery bypass grafting (OPCABG). Methods The PubMed, EMbase, The Cochrane Library, Web of Science, Wanfang data, CBM, VIP, CNKI were searched by computer for researches on risk factors associated with the development of AKI after OPCABG from the inception to March 2022. The meta-analysis was performed using RevMan 5.4 software. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of included studies. Results A total of 18 researches were included, involving 9 risk factors. The NOS score of all included studies was≥6 points. Meta-analysis results showed that age [OR=1.03, 95%CI (1.01, 1.06), P=0.020], body mass index (BMI) [OR=1.10, 95%CI (1.05, 1.15), P<0.001], history of hypertension [OR=1.45, 95%CI (1.27, 1.66), P<0.001], history of diabetes [OR=1.50, 95%CI (1.33, 1.70), P<0.001], preoperative serum creatinine level [OR=2.05, 95%CI (1.27, 3.32), P=0.003], low left ventricular ejection fraction [OR=4.51, 95%CI (1.39, 14.65), P=0.010], preoperative coronary angiography within a short period of time [OR=2.10, 95%CI (1.52, 2.91), P<0.001], perioperative implantation of intra-aortic balloon pump [OR=3.42, 95%CI (2.26, 5.16), P<0.001], perioperative blood transfusion [OR=2.00, 95%CI (1.51, 2.65), P<0.001] were risk factors for AKI after OPCABG. Conclusion Age, BMI, history of hypertension, history of diabetes, preoperative serum creatinine level, low left ventricular ejection fraction, preoperative coronary angiography within a short period of time, perioperative implantation of intra-aortic balloon pump, perioperative blood transfusion are risk factors for AKI after OPCABG. Medical staff should focus on monitoring the above risk factors and early identifying, in order to prevent or delay the onset of postoperative AKI and promote early recovery of patients.

Objective:To investigate the impact of " staging" hybrid coronary artery revascularization (HCR) on the short-and long-term efficacy of patients with multiple coronary artery lesions.Methods:A retrospective case-control study was conducted. Eighty patients with multiple coronary artery lesions admitted to the Baoding Second Central Hospital from January 2017 to October 2018 were selected and divided into two groups according to different surgical methods. Forty patients were treated with " staging" HCR and were designated as the HCR group, and 40 patients were treated with off-pump coronary artery bypass grafting (OPCAB) and were designated as the OPCAB group. The perioperative related indicators and perioperative serious complications were compared between the two groups. The serum myocardial injury marker levels were detected preoperatively and 48 hours postoperatively, including heart-type fatty acid binding protein (H-FABP) and troponin I (cTnI). All subjects were followed up for at least 3 years to calculate the incidence of major adverse cardiovascular and cerebrovascular events (MACCE).Results:The bypass surgery time, mechanical ventilation time, ICU stay time, and total hospital stay time in the HCR group were all less than those in the OPCAB group (all P<0.05), and the incision length in the HCR group was shorter than that in the OPCAB group ( P<0.05). The intraoperative bleeding volume, postoperative 24-hour drainage volume, red blood cell transfusion volume, and plasma transfusion volume in the HCR group were all less than those in the OPCAB group (all P<0.05). Forty-eight hours after surgery, the serum H-FABP and cTnI levels in both groups were significantly higher than those preoperatively (all P<0.05), but the increase was more significant in the OPCAB group (all P<0.05). The perioperative serious complication rate in the HCR group was 2.50%(1/40), which was significantly lower than that in the OPCAB group [20.00%(8/40)] ( P<0.05). During the 3-year follow-up after surgery, the MACCE incidence in the HCR group was 12.50%(5/40), and that in the OPCAB group was 22.50%(9/40). There was no significant difference in the long-term MACCE incidence between the two groups ( P>0.05). Conclusions:" Staging" HCR treatment for multiple coronary artery lesions can achieve ideal surgical results. Compared with OPCAB, its short-term efficacy is more significant, and long-term efficacy is equivalent.

ABSTRACT Introduction: Despite its survival benefits, bilateral internal thoracic artery (BITA) grafting is not commonly utilized due to concerns over deep sternal wound infection (DSWI). We observed the role of routine use of BITA and off-pump coronary artery bypass grafting (OPCABG) in the incidence of DSWI and associated risk factors. Methods: Between January 2010 and December 2020, 1,207 patients were treated with isolated coronary artery bypass grafting. In all cases, OPCABG was attempted, and BITA was used whenever there was a need for a second arterial graft for the left coronary artery. DSWI was defined as a wound infection requiring surgical intervention and/or the administration of antibiotics. Multiple linear regression analysis was employed to model the risk of DSWI. Results: The incidence of DSWI was 0.58%. Mortality rate was higher in DSWI group than in no-DSWI group (28.57% vs. 1.25%; P<0.001). No significant difference in DSWI incidence was observed when BITA (70.6%) or single internal thoracic artery (29.4%) were used (P=0.680). The prevalence of diabetes (100% vs. 40.7%; P=0.001), hyperlipidemia (100% vs. 85.9%; P=0.045), and obesity (71.4% vs. 26.8%; P-0.017) was significantly elevated in DSWI group, when compared with no-DSWI group. Diabetes (P=0.0001), unstable angina (P=0.0064), previous myocardial infarction > 30 days (P=0.0009), left ventricular ejection fraction < 50% (P=0.0074), and emergency surgery (P=0.0002) were independent risk factors. Conclusion: The results of routine use of skeletonized BITA after OPCABG were satisfactory regarding DSWI incidence and operative mortality in a single-center experience.

ABSTRACT Introduction: Risk factors and postoperative complications can worsen the condition of patients undergoing coronary artery bypass grafting; some of these factors and complications are closely related to mortality rate. Objective: To describe clinical factors and outcomes related to mortality of patients undergoing coronary artery bypass grafting and on invasive mechanical ventilation. Methods: This is a single-center retrospective data analysis of patients who underwent coronary artery bypass grafting on invasive mechanical ventilation between 2013 and 2019. Data regarding clinical characteristics, postoperative complications, intensive care unit and mechanical ventilation time, and their relationship with mortality were analyzed. Results: Four hundred seventy-two patients who underwent coronary artery bypass grafting entered the study. Their mean age was 62.3 years, and mean body mass index was 27.3. The mortality rate was 4%. Fifty percent of the patients who had ventilator-associated pneumonia died. Considering the patients who underwent hemotherapy and hemodialysis, 20% and 33% died, respectively. Days of intensive care unit stay and high Acute Physiology and Chronic Health Evaluation score and Simplified Acute Physiology Score were significantly related to death. Conclusion: Factors and clinical conditions such as the patients' age, associated comorbidities, the occurrence of ventilator-associated pneumonia, length of stay in the intensive care unit, and mechanical ventilation time are related to higher mortality in patients undergoing coronary artery bypass grafting.

ABSTRACT Introduction: We propose a new technique for box-lesion ablation combined with off-pump coronary artery bypass grafting for the treatment of patients with coronary artery disease and paroxysmal or persistent atrial fibrillation. Methods: Eight male patients with paroxysmal (n=2) or persistent atrial fibrillation (n=6) and coronary artery disease underwent box-lesion ablation combined with off-pump coronary artery bypass grafting. Box-lesion ablation was performed using a bipolar flexible clamping device with irrigated electrodes which was originally designed for thoracoscopic epicardial ablation. Results: Complete revascularization was performed in all patients. There were no deaths or major complications. At a median follow-up of 14 months, seven patients (87.5%) were in sinus rhythm. Conclusion: Box-lesion ablation can be easily and effectively combined with coronary artery surgery in an off-pump setting.
