Objective To explore the factors affecting the operation of coronary artery bypass grafting with heart beating and improve the effect of the operation. MethodsFrom January 2012 to June 2016, 898 patients with coronary heart disease who received cardiovascular surgery in the Second Affiliated Hospital of Jilin University were analyzed retrospectively. All patients only underwent coronary artery bypass grafting with beating heart. Among them, 797 patients underwent the off-pump coronary artery bypass grafting (an OPCABG group, 592 males and 205 females, with an average age of 60.5±8.4 years); another 101 patients received on-pump beating heart coronary artery bypass grafting (an OPBH group, 77 males and 24 females, with an average age of 61.5±8.2 years). ResultsThe average number of grafts in the OPCABG group was 3.36±0.74, and in the OPBH group was 3.71±0.69 (P<0.05). The postoperative ventilation time (10.8±9.5 h vs. 20.6±12.3 h), ICU stay (28.8±15.5 h vs. 37.4±30.8 h), hospital stay (10.9±4.8 d vs. 14.8±8.6 d), mortality (1.1% vs. 3.0%), the utilization rate of intra-aortic balloon pump (2.4% vs. 8.9%) and extracorporeal membrane oxygenation (0.5% vs. 5.0%) were significantly different between the OPCABG group and OPBH group (all P<0.05). Twelve patients died after surgery, and the total bloodless operation ratio was 91.3%. ConclusionThe results show that most patients can achieve good results with the help of apical fixation and myocardial fixator, improved surgical techniques and methods, good anesthesia management as well as flexible and accurate use of vasoactive drugs. But extracorporeal circulation is necessary in the patients with large left ventricle, low ejection fraction and hemodynamic instability after intraoperatively moving the heart.
Objective To compare and analyze the early- to mid-term outcomes of transcatheter aortic valve replacement (TAVR) combined with percutaneous coronary intervention (PCI) versus surgical aortic valve replacement (SAVR) combined with coronary artery bypass grafting (CABG) for the treatment of significant aortic stenosis (AS) and coronary artery disease (CAD). Methods The data of patients with significant AS and CAD who underwent surgical treatment at Central China Fuwai Hospital of Zhengzhou University from January 2018 to July 2023 were collected. These patients were divided into a TAVR+PCI group and a SAVR+CABG group according to the operation method. Propensity score matching (PSM) was used to select patients with close clinical baseline characteristics, and the early- to mid-term outcomes of the two groups were compared. Results A total of 272 patients were enrolled, including 208 males and 64 females, with a mean age of 64.16±8.24 years. There were 47 patients in the TAVR+PCI group and 225 patients in the SAVR+CABG group. After 1∶1 PSM, 32 pairs were selected. There was no statistical difference in baseline data between the two groups (P>0.05). Compared with the SAVR+CABG group, the TAVR+PCI group had significantly shorter operative time, mechanical ventilation time, ICU stay, postoperative hospital stay, and less intraoperative bleeding, and significantly lower postoperative transfusion and complete revascularization rates (P<0.05). The differences in the rates of postoperative in-hospital death, myocardial infarction, stroke, and other complications between the two groups were not statistically significant (P>0.05), and the differences in the rates of severe perivalvular leakage, death, or readmission in the mid-term follow-up were not statistically significant (P>0.05). Conclusion In patients with significant AS and CAD, the early- and mid-term rates of death and complications were similar between those treated with TAVR+PCI and SAVR+CABG, and TAVR+PCI is a safe alternative to SAVR+CABG.
ObjectiveTo evaluate the association between extent and severity of acute coronary syndrome and uric acid, leukocytes. MethodsA retrospective analysis of leukocytes, platelets, lipids and uric acid levels were performed on 23 patients with acute myocardial infarction (AMI group), 17 patients with unstable angina (UA group), and 17 healthy subjects (controls) between January and December 2010. ResultsIn the three groups (AMI, UA, and Control), the leukocyte count was respectively (10.4±3.2)×109/L, (6.9±2.4)×109/L and (5.4±1.1)×109/L (P<0.05); neutrophil was (7.4±3.2)×109/L, (4.8±2.3)×109/L, and (3.4±0.8)×109/L (P<0.001); and uric acid was (401.4±94.3), (384.1±74.1) and (285.5±76.8) μmol/L, respectively (P<0.001). Multinomial Logistic regression showed leukocyte was a predictor for AMI (OR=1.712, P=0.003), while uric acid was not (OR=1.006, P=0.255), regarding the UA group as the reference. When the control group was using as reference, leukocyte was an independently significant factor for AMI (OR=2.942, P=0.004) and was not a significant factor for UA (OR=1.718, P=0.125); uric acid was a significant factor for AMI and UA (OR=1.027, P=0.016; OR=1.021, P=0.041). ConclusionUric acid may be associated with the chronic development of coronary heart disease, while leukocytes may play a potential role in plaque destabilization and the onset of AMI.
Technical advances both in cardiac surgery and relating to anesthesia,cardiopulmonary bypass and myocardial protection have significantly improved the prognosis for patients combined with coronary heart disease and heart valve disease. In addition to technology, variable factors that affect operative survival following combined operation include the severity of valvular disease, the number of coronary vessels affected, impairment of left ventricular function and both age and gender differences. In this article, we review the outcome of surgical intervention for heart valve disease combined with coronary heart disease and discuss future prospects in this field.
ObjectiveTo evaluate the short- and mid-term outcomes of sequential anastomosis and simple anastomosis of saphenous vein in off-pump coronary artery bypass grafting.MethodsThe clinical data of 438 patients who underwent sequential anastomosis of saphenous vein and 165 patients who underwent simple anastomosis of saphenous vein from 2015 to 2018 in Daxing Teaching Hospital were retrospectively analyzed. After propensity score matching, 130 pairs of patients were included in the sequential anastomosis group [78 males and 52 females, aged 60 (52, 68) years] and simple anastomosis group [80 males and 50 females, aged 61 (52, 70) years]. The short- and mid-term clinical outcomes were compared.ResultsThe two propensity score-matched groups had similar baseline clinical data. No significant difference was found between sequential anastomosis and simple anastomosis groups in the in-hospital outcomes, including in-hospital death (1.5% vs. 1.5%, P=1.000), the incidence of complications (4.6% vs. 6.2%, P>0.05), and the mean flow of grafts (30.0±11.8 mL/min vs. 28.0±9.5 mL/min, P=0.597). The operation time of the sequential anastomosis group was shorter than that of the simple anastomosis group (142.5±21.2 min vs. 186.3±27.6 min, P<0.001). The drainage of the sequential anastomosis group was less than that of the simple anastomosis group (204.7±39.6 mL vs. 271.3±48.3 mL, P<0.001). The follow-up time was 12-60 (28.3±8.9) months, during which the mortality of the two groups was not statistically different (3.2% vs. 4.0%, P=0.796).ConclusionThe saphenous vein sequential anastomosis of saphenous vein is superior to the simple anastomosis. Sequential anastomosis technique can reduce aortic anastomosis, shorten operation time, and reduce bleeding drainage during off-pump coronary artery bypass grafting. The short- and mid- term clinical effects are satisfactory.
ObjectiveTo evaluate the perioperative, short- and mid-term results of total artery bypass grafting and saphenous vein bypass grafting in three-vessel coronary heart disease patients complicated with diabetes.MethodsRetrospective analysis was performed on 46 patients (a TAR group) including 36 males and 10 females with an average age of 65.1±11.3 years who underwent total artery bypass grafting in Renji Hospital affiliated to Shanghai Jiao Tong University Medical College from 2005 to 2014. A total of 46 patients with age and gender matched admitted during the same period were selected as a control group (NCR group), in which left internal mammary artery and great saphenous vein were used as grafting vessels. Preoperative, perioperative, and postoperative (1 year and 5 years) data of the two groups were analyzed.ResultsIn terms of perioperative data, the TAR group was inferior to the NCR group in operation time, postoperative 24 h drainage volume and postoperative 24 h blood transfusion volume. However, there was no difference between the two groups in terms of perioperative mortality, ICU stay, etc. One year after surgery, there was no difference in angina pectoris recurrence, recurrent myocardial infarction or grafting vessel patency rate between the two groups. Five years after the operation, the TAR group was superior to the NCR group in angina recurrence, myocardial infarction, and grafting vessels patency rate.ConclusionFor patients with three-vessel coronary heart disease complicated with diabetes, total arterial bypass grafting can achieve better mid-term effect, although it can prolong the operation time and increase the amount of drainage and blood transfusion 24 h after operation.
ObjectiveTo evaluate the efficacy of staged carotid artery stenting and coronary artery bypass grafting in the treatment of coronary heart disease complicated with carotid stenosis. MethodsThe clinical data of patients with coronary heart disease and carotid stenosis treated in Fuwai Hospital from November 2019 to September 2021 were retrospectively analyzed. All patients underwent staged carotid artery stenting and coronary artery bypass grafting. The incidence and risk factors of severe complications such as myocardial infarction, cerebral infarction and death during the perioperative period and follow-up were analyzed. ResultsA total of 58 patients were enrolled, including 47 males and 11 females with an average age of 52-77 (64.2±5.6) years. No complications occurred before coronary artery bypass grafting. There was 1 myocardial infarction, 1 cerebral infarction and 1 death after the coronary artery bypass grafting. The early complication rate was 5.2%. During the follow-up of 18.3 months, 1 cerebral infarction and 2 deaths occurred, and the overall complication rate was 10.3%. According to Kaplan-Meier survival curve analysis, patients with symptomatic carotid stenosis (log-rank, P=0.037) and placement of close-cell (log-rank, P=0.030) had a higher risk of postoperative ischemic cerebrovascular event, and patients with previous cerebral infarction had a higher risk of postoperative severe complications (log-rank, P=0.044). ConclusionStaged carotid artery stenting and coronary artery bypass grafting is safe and feasible for the treatment of coronary heart disease complicated with carotid stenosis.
Patients undergoing coronary artery bypass grafting (CABG) belong to the very high-risk group of atherosclerotic cardiovascular disease. Although CABG gets advantages in relieving symptoms and improving long-term outcomes, a significant risk of cardiovascular adverse events after surgery still exists and standardized secondary prevention is needed. Lipid management plays a critical role as a secondary preventive strategy in CABG. However, lipid management of CABG patients in real clinical setting is inadequate, including lack of standardized lipid-lowering strategy, low goal attainment rate, as well as poor long-term medication adherence. In recent years, a series of clinical trials have provided a lot of groundbreaking new evidence for lipid management in patients with cardiovascular diseases which offers new strategies together with objectives of lipid-lowering and comprehensive management for patients undergoing CABG. This article reviews the strategy and research progress of lipid management after CABG, aiming to provide objective reference for clinical treatment.
ObjectiveTo 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.MethodsFrom 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.ResultsThere 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.ConclusionOn-pump CABG via left anterolateral minithoracotomy is safe for appropriately selected patients.
