ABSTRACT
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.
ABSTRACT
Protamine is a routinely used safe antidote for heparin reversal in cardiovascular surgeries. Protamine was first introduced to prolong the action of insulin preparations. As protamine interacts with platelets and fibrinogen and has an anticoagulant effect of its own, minimal amount is given to neutralize heparin present in plasma. Although infrequent, protamine is associated with serious adverse drug reactions (ADRs), especially in patients with previous history of protamine hypersensitivity. Here, we report a case of protamine-induced pulmonary arterial hypertension and peripheral vascular collapse in a 60-year-old diabetic male patient who had undergone on-pump coronary artery bypass grafting in a tertiary care center. This was a definite, nonpreventable, severe ADR as per causality, preventability, and severity assessment scale. This patient had no previous history of protamine hypersensitivity and was not on any insulin preparations. Despite precise timely treatment and other resuscitative measures, the patient expired subsequent to these ADRs. This case report throws light on the grave requirement in urgent evolvement of pharmacogenetic and pharmacokinetic tools to detect patients who are at risk of precipitating these ADRs and thus to take precautions to prevent them
ABSTRACT
@#Objective To analyze the safety and follow-up results of on-pump coronary artery bypass grafting (CABG) for the treatment of multivessel diseases via left anterolateral minithoracotomy. Methods From January 2018 to March 2020, a total of 30 patients including 18 males and 12 females with an average age of 61.3±7.5 years having multivessel coronary heart diseases were treated in our hospital with on-pump CABG via left anterolateral minithoracotomy. Among them, 14 patients had three-vessel diseases and 16 patients had two-vessel diseases. Results There were 29 internal mammary artery-to-left anterior descending bypass grafts harvested in total while the rest were saphenous-vein bypass grafts. The average number of bypass vessels was 2.3±0.5. There was no perioperative death in the whole group, one patient underwent rethoracotomy due to hemorrhage, and one patient suffered acute renal insufficiency. The average time of postoperative tracheal intubation was 16.0±5.8 hours, and the postoperative ICU stay was 30.1±11.5 hours. Twenty five patients were followed up, including coronary CT angiography examinations at 6 months and 1 year after operation. Proximal anastomotic stenosis in one patient and distal anastomosis occlusion in one patient occurred. Conclusion On-pump CABG via left anterolateral minithoracotomy is safe for appropriately selected patients.
ABSTRACT
@#Objective To explore the difference of myocardial injury between off-pump coronary artery bypass grafting (OPCAB) and modified perfusion on-pump coronary artery bypass grafting (ONCAB). Methods A total of 558 patients who underwent coronary artery bypass grafting in Beijing Anzhen Hospital from 2017 to 2019 were included. According to whether or not they received modified perfusion cardiopulmonary bypass, all the 558 patients were divided into two groups including an OPCAB group (OP group) and an ONCAB group (ON group). There were 465 patients in the OP group including 282 males and 183 females with an average age of 63.58±7.87 years. In the ON group, there were 93 patients including 64 males and 29 females with an average age of 63.91±7.51 years. Creatine kinase MB (CK-MB) and cardiac specific troponin I (cTnI) were measured 24 hours before operation, 30 minutes after operation, 12 hours after operation, 36 hours after operation and 48 hours after operation. Results No perioperative death occurred in all patients. CK-MB (5.00 ng/mL vs. 8.60 ng/mL, Z=–2.189, P=0.029) and cTnI (3.00 ng/mL vs. 7.80 ng/mL, Z=–5.307, P=0.000) in postoperative 12 hours in the ON group were less than those in the OP group. CK-MB (5.00 ng/mL vs. 5.60 ng/mL, Z=–2.280, P=0.023) and cTnI (0.10 ng/mL vs. 1.02 ng/mL, Z=–6.418, P=0.000) in postoperative 36 hours in the ON group were less than those in the OP group. cTnI (0.07 ng/mL vs. 0.81 ng/mL, Z=–1.946, P=0.032) in postoperative 48 hours in the ON group was less than that in the OP group. Conclusion Compared with OPCAB, modified perfusion ONCAB has less myocardial damage.
ABSTRACT
Data on isolated coronary artery bypass grafting (CABG) performed in 2017 and 2018, and registered in the Japan Cardiovascular Surgery Database were reviewed for preoperative characteristics, postoperative outcomes, and choice of graft material for the left anterior descending artery (LAD). Isolated CABG was performed off-pump in 54.6% (n＝14,684) of all CABG cases (n＝26,913), and graft material for the LAD was left internal thoracic artery in 76.4% and right internal thoracic artery in 19.0%. Operative mortality was 1.5% in elective cases (On-pump CABG : ONCAB 1.9%, off-pump CABG : OPCAB 1.2%, p＜0.001), 7.4% in emergency cases (ONCAB 10.2%, OPCAB 4.3%, p＜0.001), and 2.5% overall. Postoperative morbidity was low in almost all aspects in OPCAB, and average JapanSCORE II is elevating every year. Overall short-term operative results for isolated CABG is stable, and operative candidates are shifting to higher-risk patients.
ABSTRACT
We reviewed the data of the isolated coronary artery bypass grafting (CABG) procedures performed in 2015 and 2016, as registered in the Japan Cardiovascular Surgery Database, for preoperative characteristics, surgical outcomes, and the choice of graft material used for the left anterior descending artery (LAD). Isolated CABG was performed off-pump in 55.0% (n = 16,173) of all CABG cases (n = 29,392). The left internal thoracic artery and the right internal thoracic artery were used as the graft materials in 72.1 and 17.4% cases respectively. The operative mortality rates remained unchanged since the last report, with 1.7% for elective cases, 8.8% for emergency cases, and 3.0% overall. In elective cases, the operative mortality rate was 1.1% for off-pump CABG (OPCAB) compared with 2.5% for on-pump CABG. The morbidity rates for all OPCAB cases were significantly better except for those falling in the ‘readmission ＜30 days’ group.

ABSTRACT
Objective To compare the long-term complications of off-pump and on-pump coronary artery bypass grafting. Methods CNKI, WanFang Data, VIP, PubMed, EMBASE and the Cochrane Central Register were searched for randomized controlled trials (RCTs) of long-term complications of off-pump and on-pump coronary artery bypass grafting. According to the Cochrane system evaluation method, the quality of the research literature was evaluated by the inclusion and exclusion criteria, and the RevMan5.2 software was used for meta analysis. Results A total of 9 studies were included, including 11 660 patients, 5 794 patients in the OPCABG group and 5 866 cases in the ONCABG group. There was no significant difference in mortality between the OPCABG group and the ONCABG group (OR=1.10, 95%CI:0.94-1.30,P=0.22] and no significant difference in myocardial infarction (OR=0.90, 95%CI:0.76-1.06,P=0.21). However, the difference in revascularization was statistically significant between the two groups (OR=1.41, 95%CI:1.09-1.83,P=0.009). The long-term incidence of stroke was significantly lower in OPCABG group than that of ONCABG group (OR=0.75, 95%CI: 0.57-0.98,P=0.04]. Conclusion The on-pump coronary artery bypass grafting can effectively reduce the occurrence of long-term revascularization. However, off-pump coronary artery bypass grafting can effectively reduce the risks of stroke.
