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.
ObjectiveTo compare the superiority of total arterial revascularization in patients with coronary artery disease (CAD) complicated with left ventricular dysfunction. MethodsThis retrospective study included the patients who were diagnosed with CAD and the left ventricular ejection fraction (LVEF) of ≤40% and underwent coronary artery bypass grafting (CABG) at our hospital from January 2016 to July 2019. The patients were divided into two groups according to the different types of bypass vessels: a total arterial revascularization group (TAR group) and a conventional group (a CON group). The clinical data were compared between the two groups to explore the incidence of important complications and evaluate the safety of total arterial revascularization and its protective effect on cardiac function. Results Finally 75 patients were enrolled including 52 males and 23 females with a mean age of (61.58±7.93) years. There were 35 patients in the TAR group and 40 patients in the CON group. The operation time and the drainage volume at 24 hours after operation in the TAR group were longer or more than those in the CON group (P<0.001), but there was no statistical difference in hospital stay, postoperative complications (such as respiratory failure, mediastinal infection, renal failure), intra-aortic balloon pump or extracorporeal membrane oxygenation use rate (P>0.05). After 2 years of follow-up, compared with the CON group, the cardiac function of the TAR group was significantly improved, the LVEF was higher, the left ventricular end diastolic diameter was reduced, and the graft stenosis rate was lower (all P<0.05). Conclusion Total arterial revascularization is a safe and feasible surgical method, which is helpful to improve the cardiac function and improve the quality of life.
Objective To introduce the technique of surgical patch angioplasty for the treatment of patients with isolated left main coronary artery stenosis. Methods Retrospective investigation of results of surgical patch angioplasty in patients with isolated left main coronary artery disease. Results All 8 patients who underwent left main coronary artery patch angioplasty survived with no major perioperative complications. One patient had recurrent angina and required coronary artery bypass grafting 6 months after patch angioplasty. All other patients were symptom free and had normal activity, at a mean follow-up of 5. 3 years. Conclusions Patch angioplasty can be used as an alternative surgical technique in cases of isolated left main coronary artery stenosis with no distal coronary artery disease. However, it may not be suitable for patients with significant left main coronary artery calcification.
The coronary artery disease is a frequent severe disease of cardiovascular system in recent years. Meanwhile, lung cancer, with its high morbidity and mortality, is the most frequent malignant tumor of respiratory system in the world. Clinical studies have shown that the incidence of coronary artery disease and lung cancer is high throughout the year, and comorbidities are becoming more common, especially in elderly patients. The incidence of lung cancer and coronary heart disease may be related. This article summarizes the common risk factors (smoking and environmental pollution, fibrinogen, estrogen, and age), and treatment (surgical treatment, neoadjuvant therapy, and targeted therapy) progress of the two diseases, providing a theoretical basis for clinical prevention and treatment.
This study aimed to explore the possible association between single nucleotide polymorphism (SNP) rs189037 C > T in the promoter region of ataxia telangiectasia mutated (ATM) gene and essential hypertension (EH). We performed a case-control study to collect randomly 369 hospitalized patients aged 50 years and above. They were divided into EH group (190 patients) and control group (179 subjects) according to the diagnostic criteria of hypertension. The SNP rs189037 genotyping was performed using polymerase chain reaction-restriction fragment length polymorphism. The genotype frequencies of ATM gene polymorphism rs189037 for the whole sample were 33.9% CC, 48.0% CT, and 18.1% TT. There was no significant difference in the genotype frequency distributions of the SNP rs189037 between EH and control groups (P=0.619). After adjustment of the major confounding factors, the SNP rs189037 was still not associated with EH (P > 0.05). We further analyzed data from different groups divided by genders and age respectively, and the relationship was retained (P > 0.05). In addition, we found that the percentage of the TT genotype was much lower in coronary artery disease (CAD) patients than those in the CC or CT genotype (OR=0.49, 95% CI=0.26~0.90, P=0.021). In conclusion, our study suggests that SNP rs189037 in the promoter of ATM gene is not associated with EH. But it is related to the incidence of CAD, and TT genotype seems to be a protective factor for CAD.
ObjectiveTo describe our experiences of application of off-pump coronary artery bypass grafting surgery (OPCABG) in coronary artery disease (CAD) patients with dilated left ventricle.MethodsA retrospective analysis of 303 patients with dilated left ventricle [left ventricular end-diastolic diameter (LVEDD)> 60 mm] who underwent OPCABG from January 2008 to December 2018 at a single center was conducted. There were 205 males and 98 females at age of 45-87 (66.9±9.3) years.ResultsThe mean pulmonary artery pressure in 90 patients was more than 25 mm Hg. Sixteen patients underwent OPCABG with emergent transition of extracorporeal circulation (CPB). Twenty-one patients underwent OPCABG with CPB at the beginning of CABG. Thirty-five patients underwent intra-aortic balloon counterpulsation (IABP). Four patients died during in-hospital time with the experience of emergent transition of CPB. Six months after operation, LVEDD and left ventricular ejection fraction (LVEF) were improved.ConclusionOPCABG is a safe and effective alternative for CAD patients with dilated left ventricle. However, for patients with higher pulmonary pressure and a spherical left ventricle after cardiac reshaping, there is a high risk of emergent transition of CPB during OPCABG; for this kind of patients, it is necessary to start CPB at the beginning of OPCABG.
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, or other complications between the two groups were not statistically significant (P>0.05), and the differences in the rates of moderate-to-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 are similar between those treated with TAVR+PCI and SAVR+CABG, and TAVR+PCI is a safe alternative to SAVR+CABG.
ObjectiveTo investigate the early clinical efficacy of minimally invasive cardiac surgery coronary artery bypass grafting (MICS CABG) via left intercostal small incision for multivessel coronary artery disease. MethodsThe patients who received off-pump CABG in the Central China Fuwai Hospital of Zhengzhou University from June 2021 to June 2023 were enrolled. Patients were divided into two groups according to the operative technique used, including a traditional midline sternotomy group and a left intercostal small incision group. The clinical data of the two groups were compared. ResultsA total of 143 patients were enrolled, including 70 patients in the traditional midline sternotomy group and 73 patients in the left intercostal small incision group. The age of the patients in the left intercostal small incision group and the traditional midline sternotomy group was (63.8±8.0) years and (63.0±7.8) years, respectively; the proportions of males were 69.9% and 74.3%, respectively. The differences were not statistically significant (all P>0.05). All patients in the two groups successfully completed the operation, and no patients in the left intercostal small incision group were converted to thoracotomy. The patients in the left intercostal small incision group showed less postoperative drainage within postoperative 24 hours [(239.4±177.7) mL vs. (338.0±151.9) mL, P<0.001], lower perioperative blood transfusion rate [32.9% (24/73) vs. 51.4% (36/70), P=0.028], higher postoperative myoglobin level within postoperative 24 hours [366.1 (247.9, 513.0) ng/mL vs. 220.8 (147.2, 314.9) ng/mL, P<0.001], shorter intensive care unit stay [45.5 (31.5, 67.5) h vs. 68.0 (46.0, 78.5) h, P=0.001] and postoperative hospital stay [(10.8±4.0) d vs. (13.1±5.3) d, P=0.028] compared to the traditional midline sternotomy group. There was no significant difference in the incidence of major adverse cardiac and cerebrovascular event between the two groups [2.7% (2/73) vs. 2.9% (2/70), P=1.000]. ConclusionCompared to the full median sternotomy, MICS CABG leads to a good clinical result with smaller trauma, faster overall recovery, and less perioperative blood transfusion.
ObjectiveTo analyze the efficacy of one-stop carotid endarterectomy (CEA) and off-pump coronary artery bypass grafting (OPCABG) for patients with coronary artery disease (CAD) combined with carotid artery stenosis. MethodsThe clinical data of patients with CAD and severe carotid artery stenosis who underwent one-stop CEA and OPCABG in our department from March 2018 to June 2021 were retrospectively analyzed. Before the surgery, all patients routinely underwent coronary and carotid angiography to diagnose CAD and carotid artery stenosis. All patients underwent CEA first and then OPCABG in the simultaneous procedure. ResultsA total of 12 patients were enrolled, including 9 males and 3 females, aged 58-69 (63.7±3.4) years. All patients had unilateral severe carotid artery stenosis, and the degree of stenosis was 70%-90%. The lesions of carotid artery stenosis were located in the bifurcation of carotid artery or the beginning of internal carotid artery. All patients successfully underwent one-stop CEA combined with OPCABG. The number of bridging vessels was 2-4 (2.8±0.6). The operation time of CEA was 16-35 (25.7±5.6) min. There was no death during the perioperative or follow-up periods. No serious complications such as stroke and myocardial infarction occurred during the perioperative period. During the follow-up of 6-40 months, the patency rate of arterial bridge was 100.0% (12/12), and that of venous bridge was 95.5% (21/22). Cervical vascular ultrasound showed that the blood flow of carotid artery was satisfactory. ConclusionOne-stop CEA and OPCABG can be safely and effectively used to treat CAD and carotid artery stenosis. The early and middle-term curative effect is satisfactory.
ObjectiveTo systematically review the long-term efficacy of coronary artery bypass grafting (CABG) versus drug-eluting stent implantation (DES-PCI) for patients with multivessel coronary artery disease. MethodsWe searched The Cochrane Library (Issue 2, 2015), PubMed, EMbase, CBM, CNKI, WanFang Data and VIP to collect randomized controlled trials (RCTs) about CABG versus DES-PCI for patients with coronary multivessel disease from the inception to October 2015. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then meta-analysis was performed by using RevMan 5.2 software. ResultsA total of seven RCTs, involving 5 723 patients were included. The results of meta-analysis showed that: compared with the DES-PCI group, the CABG group had lower 1-year incidence of target vessel revascularization (OR=0.39, 95%CI 0.31 to 0.48, P<0.000 01), 5-year mortality (OR=0.78, 95%CI 0.65 to 0.94, P=0.008), and 5-year incidence of myocardial infarction (OR=0.46, 95%CI 0.37 to 0.58, P<0.000 01). However, 1-year, 2-year and 5-year incidences of stroke in the CABG group were significantly higher than that in the DES-PCI group (all P values <0.05). ConclusionThe available evidence suggests that CABG is superior to DES-PCI for patients with multivessel coronary artery disease in long-term effects, but CABG could increase the incidence of stroke. Due to the quantity and quality of the included studies, the above conclusions still need to be verified by more high-quality RCTs.
