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.
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.
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 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 investigate the role of preoperative peripheral blood CD4/CD8 ratio in predicting the prognosis of patients with coronary atherosclerotic heart disease (CAD) after off-pump coronary artery bypass grafting (OPCABG).MethodsA total of 118 patients with CAD who underwent OPCABG in our hospital from September 2016 to April 2017 were included in the study, including 82 males and 36 females aged 62.74±4.50 years. The primary end point was the incidence of major adverse cardiovascular events (MACE). Patients were divided into a high CD4/CD8 group (≥1.40, 62 patients) and a low CD4/CD8 group (<1.40, 56 patients) according to the results of flow cytometry. The correlation between CD4/CD8 ratio and prognosis of patients after OPCABG and the value of CD4/CD8 ratio for predicting postoperative MACE were evaluated.ResultsMedian duration of follow-up was 23.25 (20.91, 24.70) months, during which 21 patients (17.80%) experienced MACE and 4 patients (3.39%) were lost to follow-up. Kaplan-Meier analysis revealed that high CD4/CD8 group had a significantly higher MACE rate than the low CD4/CD8 group did (log-rank χ2=5.797, P=0.02). The results of adjusted Cox proportional hazards model showed that CD4/CD8 ratio (HR=3.103, 95%CI 1.557-6.187, P<0.01) was an independent risk factor of MACE in patients with CAD after OPCABG. The receiver operating characteristic curve showed that area under curve was 0.778 (95%CI 0.661-0.894, P<0.01), the optimal cut off value was 2.24, the sensitivity was 57.1%, and the specificity was 87.6%.ConclusionPreoperative peripheral blood CD4/CD8 ratio is an independent predictor of MACE after OPCABG in patients with CAD.
Technical advances both in cardiac surgery and relating to anesthesia,cardiopulmonary bypass and myocardial protection have significantly improved the prognosis for patients combined with coronary heart disease and heart valve disease. In addition to technology, variable factors that affect operative survival following combined operation include the severity of valvular disease, the number of coronary vessels affected, impairment of left ventricular function and both age and gender differences. In this article, we review the outcome of surgical intervention for heart valve disease combined with coronary heart disease and discuss future prospects in this field.
Objective To explore the role of systolic and diastolic dysfunction in the prognosis of Chinese patients with coronary artery disease (CAD). Methods CAD patients who underwent coronary arteriography in the Department of Cardiology of West China Hospital between July 2008 and June 2012 were included in this study. All the patients underwent color Doppler echocardiographic examination. Based on patients’ systolic and diastolic cardiac function, left ventricular ejection fraction (LVEF) <55% was as the systolic dysfunction and the ratio of mitral peak velocity of early filling to early diastolic mitral annular velocity (E/e’) >15 was as the diastolic dysfuntion. They were divided into normal cardiac function group (LVEF≥55%, E/e’ ratio≤15), systolic and diastolic dysfunction group (LVEF<55%, E/e’ ratio>15), diastolic dysfunction group (LVEF≥55%, E/e’ ratio>15) and systolic dysfunction group (LVEF<55%, E/e’ ratio≤15). The end points of follow-up were all-cause death and a major cardiovascular event (MACE). Results A total of 985 patients with complete echocardiographic report were included in this study. During the follow-up of (21.4±9.7) months, 46 patients (4.7%) died, and 52 (5.4%) had a MACE. Systolic dysfunction concomitant with diastolic dysfunction group and systolic dysfunction group patients had a higher risk of 36-month all-cause death (4.8%, 10.7%,P<0.001) and a higher risk of 41-month MACE (8.6%, 7.6%,P=0.028). Single factor analysis of all-cause death mortality showed that compared with the normal group, all-cause death mortality was the highest in systolic and diastolic dysfunction group (P<0.05), followed by diastolic dysfunction group (P<0.05) and systolic dysfunction group (P>0.05). Single factor analysis of MACE showed that compared with the normal group, MACE was still the highest in systolic and diastolic dysfunction group (P<0.05), followed by systolic dysfunction group (P<0.05) and diastolic dysfunction group (P>0.05). A multivariate Cox regression model analysis showed that compared with the normal group, the risk of all-cause death was the highest in the systolic and diastolic dysfunction group [hazard ratio (HR)=2.96, 95% confidence interval (CI) (1.34, 6.54),P=0.007], followed by the systolic dysfunction group [HR=1.91, 95%CI (0.67, 5.42),P=0.224] and the diastolic dysfunction group [HR=0.95, 95%CI (0.40, 2.23),P=0.905]. Conclusion Compared with normal patients, patients with either systolic or diastolic dysfunction have a poorer prognosis, and patients with systolic dysfunction concomitant with diastolic dysfunction have the poorest prognosis.
