ObjectiveTo investigate the perioperative results and safety of minimally invasive direct coronary artery bypass grafting (MIDCAB) treatment of anterior descending artery disease through a small left thoracic incision assisted by thoracoscopy. MethodsThe clinical data of 92 patients who received MIDCAB in our hospital from May 2014 to October 2018 were retrospectively analyzed, including 72 (78.26%) males aged 42-78 (61.2±7.48) years, and 20 (21.74%) females aged 30-80 (61.30±12.26) years. The perioperative complications, blood product use, left heart function changes, ventilator use time, ICU stay, hospital stay and other indicators were analyzed. ResultsTwo (2.17%) patients were transferred to thoracotomy, 5 (5.43%) patients received blood products during the operation, 2 (2.17%) were subjected to secondary thoracotomy to stop bleeding, 4 (4.34%) had postoperative hypoxemia and 1 (1.08%) was reintubated. The ventilator use time was 3-227 (22.35±35.39) hours, the ICU stay was 16-777 (78.85±108.62) hours, and the postoperative hospital stay was 2-36 (8.86±6.05) days. One (1.08%) patient died in hospital. ConclusionMIDCAB for anterior descending artery disease has good perioperative results, especially for solitary anterior descending artery disease, which can reduce the use of blood products, and shorten the time of ventilator use after operation, ICU stay and hospital stay.

Methods：We analyzed eGFR in the patients with coronary artery disease confirmed by coronary angiography and the control, and compared the proportion of patients with reduced renal function in the different groups. Results: A total 116 cases were included in each group. Among these patients, normal renal function, mildly and severe reduced renal function was documented in 82, 29 and 5 in coronary artery disease group, and in 98, 13 and 5 in the control group, respectively. In comparison to the control, more patients with reduced eGFR were found in coronary artery disease group (χ2 value 7.517,P=0.023), although no significant difference was observed between both groups（Pgt;0.05). Conclusion: Reduced eGFR, even if mildly, could be regarded as the risk factor of coronary artery disease.
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.
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.
Coronary artery disease (CAD) is a cardiovascular disease mainly caused by atherosclerosis, which involves a variety of pathophysiological mechanisms such as lipid metabolism, inflammatory response, and endothelial dysfunction. Fetuin B is a glycoprotein secreted by the liver, which can participate in many processes such as cell inflammation, vascular calcification, and lipid metabolism, and is closely related to the pathogenesis of CAD. This article reviews the relationship between fetuin B and CAD and the mechanism of its occurrence and development, in order to provide new choices and methods for the prevention, diagnosis, and treatment of CAD.
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.
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 significantlyimproved (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.
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.
