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.

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.
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.
Objective To evaluate the outcome and explore the mechanism of coronary vein bypass grafting （CVBG） performed by anastomosing the right internal mammary artery with the middle cardiac vein via off-pump surgery. Methods Twelve Chinese experimental miniswines （either male or female, age from 7 to 10 months, body weight 40±5 kg） with severely diffuse stenosis in the right coronary artery were randomly divided into control group and experiment group with 6 miniswines in each group, using a random number table method. CVBG was performed in the experiment group and sham surgery was performed in the control group. To assess cardiac function, graft flow, graft patency and micro-circulation reperfusion of ischemia myocardium, following measurements were conducted. Eight weeks after right coronary endarterectomy, transthoracic echocardiography was performed for both groups. Coronary angiography, graft flow and echocardiography were performed or measured 6 hours and 3 months after CVBG or sham surgery. Measurement of myocardial blood flow with non-radioactive colored microspheres was also conducted 3 months after surgery for two groups. Results There was no statistical difference in cardiac function 8 weeks after right coronary endarterectomy between the two groups. There were significant improvements in cardiac systolic and diastolic function （ejection fraction 3 months after operation: 52%±6% vs. 44%±5%, t=-2.500, P=0.031） in the experiment group after CVBG compared with the control group. Graft flow of the experiment group 6 hours and 3 months after CVBG were 44.50±5.86 ml/min and 43.33±5.01ml/min respectively （P=0.718）, and pulsatility index （PI） was 0.73±0.14 and 0.80±0.14 respectively（P=0.858）. Internal mammary artery grafts and the anastomoses were all patent without stenosis, documented by coronary artery angiography for the experiment group 6 hours and 3 months after CVBG. Myocardial flow in all aspects especially in the subendocardial layer, estimated by non-radioactive colored microsphere injection, was significantly higher in the experiment group after CVBG than that of the control group, transmural flow was 0.33±0.05ml/（g ? min） vs. 0.19±0.03 ml/（g ? min） （P＜0.05）. Conclusion Ischemic conditions of the myocardium can be relieved by CVBG using internal mammary artery in a short-term to medium-term period. The mechanism may be due to improvement of the myocardial micro-circulation.
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.
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.

ObjectiveCompare the therapeutic effects of multivessel percutaneous coronary intervention (MV-PCI) and culprit-only revascularization strategy (C-PCI) in percutaneous coronary intervention (PCI) for patients with acute myocardial infarction complicated by cardiogenic shock (AMICS) and multivessel disease (MVD). MethodsThe PubMed, Embase, Cochrane Library, MEDLINE, Web of Science, CENTRAL, CNKI and WanFang Data databases were searched to collect studies comparing C-PCI vs. MV-PCI in patients with AMI and CS from inception to March 2, 2025. Methodological quality of the included studies was assessed using the Newcastle-Ottawa scale (NOS) and the risk of bias (ROB) tool. Meta-analysis was performed using RevMan software (version 5.4.0). ResultsA total of 18 studies (1 randomized controlled trial, 1 post-hoc analysis of a randomized controlled trial, and 16 retrospective observational studies), enrolling 101 693 patients. The results of the observational studies showed that MV-PCI was associated with higher risk of short-term mortality (OR=1.13, 95%CI 1.01 to 1.25, P=0.03), renal replacement therapy (OR=1.41, 95%CI 1.32 to 1.50, P<0.00001), and cerebrovascular accident events (OR=1.21, 95%CI 1.10 to 1.33, P=0.0001). No significant difference was observed in long-term mortality (OR=0.93, 95%CI 0.74 to 1.16, P=0.51), recurrent myocardial infarction (OR=1.16, 95%CI 0.97 to 1.39, P=0.10), repeat revascularization events (OR=0.83, 95%CI 0.58 to 1.20, P=0.33) and bleeding event rates (OR=1.01, 95%CI 0.71 to 1.34, P=0.97) between groups. The results remained consistent after adding the only randomized trial.ConclusionsIn patients with AMICS and concomitant MVD, C-PCI provides comparable survival benefits to MV-PCI and is associated with a reduced risk of all-cause mortality, cerebrovascular events, and the need for renal replacement therapy.
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.
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.
