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.
The treatment of patients suffering from both severe coronary artery disease (CAD) and malignancy is different from those who have isolated CAD or tumor, because their body condition is poorer and the lesions of coronary artery are severer, which poses severe challenges to doctors. At present, the surgical treatment for these patients mainly includes staged operation and simultaneous surgery. Staged operation, which separates coronary artery revascularization surgery from tumor resection, has a lower incidence of postoperative complications, but tumor progression may occur during the waiting period. Simultaneous surgery combines heart procedure with tumor resection at the same time, shortens the treatment period of patients, overcomes the defect of tumor progression that may occur during the waiting period of the staged surgery, but the incidence of postoperative complications is higher. The progress of surgical treatment in patients with CAD combined with malignant tumor is summarized.

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.
Objective To explore the impact of diabetes on coronary artery bypass grafting （CABG） in clinical representations, operative morbidity and mortality in this hospital. Methods Data was collected as a part of prospective registry of CABG through Sep. 2001 to Jul. 2003. Four hundreds and eighty-two patients were recruited. They were divided into diabetic group （n= 135） and non-diabetic group （n=347） depended on if the patients with diabetes or not. All patients were treated with insulin for hyperglycemia. Clinical representations, operative morbidity and mortality in this hospital between two groups were compared by using chi-square tests, t tests and logistic regression. Results Re-exploration in diabetic group was higher than that in non-diabetic group （4.4% vs. 0. 9%; x2= 6. 769, P = 0. 009）. There was no significant difference in the operative morbidity and mortality in hospital between two groups. Multi-variance logistic regression showed that the lower left ventricular ejection fraction （〈 0. 40,OR 15.96）, re-exploration （OR 32. 77） and re-intubation （OR 124.17） were the predictors of perioperative mortality in hospital. Conclusions There are no significant difference in the operative mortality and complication between patients with diabetes and patients with non-diabetes. Strict glucose control in perioperative period would reduce hospital mortality and morbidity.
ObjectiveTo explore the relationship between myocardial viability in patients with coronary artery disease who underwent elective coronary artery bypass grafting (CABG) and early application of intra-aortic balloon pump (IABP) after coronary revascularization, and to provide relevant clinical reference for the pre-implantation of 16G single-lumen catheter in the femoral artery of high-risk patients to facilitate the addition of IABP after operation.MethodsThis retrospective study included 521 patients (414 males and 107 females, aged 62.50±8.82 years) who underwent positron emission tomography (PET)-computed tomography (CT) perfusion-metabolism imaging prior to CABG surgery in our institution from December 2015 to August 2020. The myocardial viability information and left ventricular functional parameters were measured, including the proportion of non-viable myocardium (perfusion-metabolic imaging match), hibernating myocardium (perfusion-metabolic imaging mismatch) and dysfunctional myocardium (non-viable+viable myocardium), left ventricular ejection fraction, left ventricular end-diastolic volume and left ventricular end-systolic volume (LVESV). The patients were divided into an IABP group and a non-IABP group according to whether they received IABP treatment after revascularization. The clinical data were reviewed and compared to explore significant impact factors between the two groups. And the multivariate logistic regression analysis was performed to investigate the correlation between preoperative myocardial viability and early use of IABP after CABG.ResultsIn multivariate logistic regression analysis, the amount of non-viable, dysfunctional myocardium and LVESV value were identified as the independent predictors for the probability of IABP use in the initial postoperative period. Receiver operating characteristic analysis showed that 9.5% non-viable myocardium, 19.5% dysfunctional myocardium, and LVESV of 114.5 mL were the optimal cutoff for predicting early IABP implantation during CABG.ConclusionThe myocardial survival status displayed by preoperative PET-CT myocardial perfusion-metabolism imaging can predict the possibility of applying IABP in CABG perioperative period. In addition to routine pre-anesthesia assessment, anesthesiologists can conduct risk stratification assessment for patients with CABG according to the results of preoperative myocardial viability imaging, which is of great significance to ensure the perioperative safety of high-risk patients with CABG.
ObjectiveTo explore the effect of skeletonized left internal mammary artery (LIMA) in coronary artery bypass grafting (CABG). MethodsA total of 122 patients who underwent pure CABG were recruited in the study in the First Affiliated Hospital of China Medical University between January and April 2013. There were 77 males and 45 females with age of 41-76(62.8±10.5) years. They were randomly assigned to received CABG with skeletonized LIMAs (group A, 60 patients) or pedicle LIMAs (the group B, 62 patients) by random digital table. LIMAs were all anastomosised to the left anterior descending artery. ResultsThere was one patient failure in harvesting LIMA process in the group A and B respectively, and they were changed to saphenous vein grafts and excluded from the criteria. There were 2 and 3 patients of postoperative myocardial infarction in the group A and in the group B respectively, with incidence rate of 3.4% and 4.9% respectively (P > 0.05). One patient died in each group during hospitalization with hospital mortality rates of 1.7% and 1.6% respectively (P > 0.05). Complications such as mediastinal infection occurred zero and one patient in the group A and in the group B respectively (P > 0.05). LIMA harvesting time of the group A was statistically longer than that of the group B (30.7±7.2 min vs. 17.2±5.6 min, P < 0.05). In six months of follow-up after surgery, coronary CT showed patency rate of LIMA in the group A and in the group B was 96.8% and 100.0% respectively (P > 0.05). ConclusionThe recent effect of skeletonized LIMA as graft material in CABG is satisfactory.
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.
