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.
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.
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.
ObjectiveTo investigate the association between TNF-α gene -308G/A polymorphism and the risk of coronary atherosclerotic heart disease (CHD) in Chinese population.MethodsWe searched PubMed, Web of Science, CNKI, WanFang Data and VIP Databases from inception to February 2017, to collect case-control studies about the association between TNF-α gene -308G/A polymorphism and risk of CHD in Chinese population. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was performed by Stata 12.0 software.ResultsA total of 10 case-control studies were included. The results of meta-analysis showed a significant association between the TNF-α gene -308G/A polymorphism and CHD risk in Chinese population (A vs. G: OR=1.13, 95%CI 1.02 to 1.26, P=0.020; AA vs. GA/GG: OR=1.47, 95%CI 1.02 to 2.12, P=0.038; AA vs. GG: OR=1.50, 95%CI 1.04 to 2.16, P=0.029).ConclusionThe current evidence shows that the TNF-α gene -308G/A polymorphism may be associated with CHD risk in Chinese population and A allele may be a risk factor. Due to the limited quantity and quality of included studies, more high quality studies are needed to verify the above conclusion.

Coronary heart disease is the second leading cause of death worldwide. As a preventable and treatable chronic disease, early screening is of great importance for disease control. However, previous screening tools relied on physician assistance, thus cannot be used on a large scale. Many facial features have been reported to be associated with coronary heart disease and may be useful for screening. However, these facial features have limitations such as fewer types, irregular definitions and poor repeatability of manual judgment, so they can not be routinely applied in clinical practice. With the development of artificial intelligence, it is possible to integrate facial features to predict diseases. A recent study published in the European Heart Journal showed that coronary heart disease can be predicted using artificial intelligence based on facial photos. Although this work still has some limitations, this novel technology will be promise for improving disease screening and diagnosis in the future.
