ObjectiveBy exploring the influencing factors of readmission in patients with stable angina of coronary heart disease （CHD） based on real-world clinical data， to establish a risk prediction model of integrated traditional Chinese and western medicine， in order to provide a basis for early identification of high-risk populations and reducing readmission rates. MethodsA prospective clinical study was conducted involving patients with stable angina pectoris of CHD， who were divided into a training set and a validation set at a 7∶3 ratio. General information， traditional Chinese medicine （TCM）-related data， and laboratory test results were uniformly collected. After a one-year follow-up， patients were classified into a readmission group and a non-readmission group based on whether they were readmitted. Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for readmission. A risk prediction model of integrated traditional Chinese and western medicine was constructed and visualized using a nomogram. The model was validated and evaluated in terms of discrimination， calibration， and clinical decision curve analysis. ResultsA total of 682 patients were included， with 477 in the training set and 205 in the validation set， among whom 89 patients were readmitted. Multivariate logistic regression analysis identified heart failure history ［OR = 6.93， 95% CI （1.58， 30.45）］， wiry pulse ［OR = 2.58， 95% CI （1.42， 4.72）］， weak pulse ［OR = 3.97， 95% CI （2.06， 7.67）］， teeth-marked tongue ［OR = 4.38， 95% CI （2.32， 8.27）］， blood stasis constitution ［OR = 2.17， 95% CI （1.06， 4.44）］， phlegm-stasis mutual syndrome ［OR = 3.64， 95% CI （1.87， 7.09）］， and elevated non-high-density lipoprotein cholesterol ［OR = 1.30， 95% CI （1.01， 1.69）］ as influencing factors of readmission. These factors were used as predictors to construct a nomogram-based risk prediction model for readmission in patients with stable angina. The model demonstrated moderate predictive capability， with an area under the receiver operating characteristic curve （AUC） of 0.818 ［95% CI （0.781， 0.852）］ in the training set and 0.816 ［95% CI （0.779， 0.850）］ in the validation set. The Hosmer-Lemeshow test showed good calibration （χ² = 4.55， P = 0.80）， and the model's predictive ability was stable. When the threshold probability exceeded 5%， the clinical net benefit of using the model to predict readmission risk was significantly higher than intervening in all patients. ConclusionHistory of heart failure， teeth-marked tongue， weak pulse， wiry pulse， phlegm-stasis mutual syndrome， blood stasis constitution， and non-high-density lipoprotein cholesterol are influencing factors for readmission in patients with stable angina of CHD. A clinical prediction model was developed based on these factors， which showed good discrimination， calibration， and clinical utility， providing a scientific basis for predicting readmission events in patients with stable angina.

OBJECTIVE To investigate the ameliorative effects and potential mechanism of total secondary ginsenosides （TSG） on hypertrophic changes of primary cardiomyocytes stimulated by angiotensin Ⅱ （Ang Ⅱ）. METHODS Primary cardiomyocytes were isolated from the hearts of neonatal SD rats and divided into the following groups： control group， AngⅡ group （2 µmol/L）， TSG group （7.5 µg/mL）， PFK-015 group [6-phosphofructo-2-kinase/fructose-2， 6-bisphosphatase 3 （PFKFB3） inhibitor， 10 nmol/L]， and TSG+PFK-015 group （TSG 7.5 µg/mL+PFK-015 10 nmol/L）. The surface area， protein synthesis， energy metabolism-related indicators [free fatty acid （FFA）， coenzyme A （CoA）， acetyl coenzyme A （acetyl-CoA）]， and the expressions of glycolysis-related factors [hypoxia-inducible factor 1α （HIF-1α）， glucose transporter protein 4 （GLUT-4）， lactate dehydrogenase A （LDHA）， pyruvate dehydrogenase kinase 1 （PDK1） and PFKFB3] in primary cardiomyocytes of each group were measured. RESULTS Compared with the control group， the surface area of primary cardiomyocytes and protein synthesis were significantly increased， the content of FFA， protein and mRNA expressions of HIF-1α， LDHA， PDK1 and PFKFB3 were significantly increased or up-regulated in the AngⅡ group， while the contents of CoA and acetyl-CoA， the protein and mRNA expressions of GLUT-4 were significantly decreased or down-regulated （P＜0.05）. Compared with the AngⅡ group， both TSG group and PFK-015 group showed significant improvements in these indexes， with the TSG+PFK-015 group generally demonstrating superior effects compared to either treatment alone （P＜0.05）. CONCLUSIONS TSG can reduce the surface area of AngⅡ-induced primary cardiomyocytes， decrease protein synthesis， and inhibit their hypertrophic changes. These effects may be related to improving energy metabolism and the inhibition of glycolysis activity.

ObjectiveTo investigate the current status of secondary prevention of stable angina in patients with coronary heart disease in three regions of China， namely Henan Province， Xinjiang Uygur Autonomous Region， and Tianjin City， and analyze the the influencing factors. MethodsA cross-sectional study was conducted to include patients with stable angina with coronary heart disease in Henan， Tianjin and Xinjiang from August 10， 2020 to March 14， 2021. General information， traditional Chinese medicine （TCM） syndrome elements， prescriptions and other data of patients were collected， and clinical characteristics， blood pressure， blood lipid and blood glucose of patients were analyzed； the patients were divided into groups according to whether their blood pressure， blood lipid and blood glucose were up to standard. With the most common syndrome element as the main variable， region， age and gender as covariables， Logistic regression equation was incorporated to analyze the influencing factors for the patients' blood pressure， blood lipid and blood glucose being up to standard. ResultsA total of 1061 coronary heart disease patients with stable angina were included， including 658 in Henan， 210 in Xinjiang， and 193 in Tianjin. The clinical characteristics of patients in the three regions showed statistical different in age， sex， disease course， complication， blood pressure， blood lipid， blood glucose， smoking， drinking， living habits， and medication treatment （P＜0.05 or P＜0.01）. For the included patients， qi deficiency （79.55%， 844/1061） and blood stasis （39.96%， 424/1061） were the main syndrome elements. The overall compliance rate of blood pressure was 48.89% （506/1035）， blood lipids 12.68% （133/1049） and blood glucose 48.18% （504/1046）. Qi deficiency was the independent factor affecting the blood pressure of coronary heart disease patients with stable angina combined with hypertension （P = 0.029，95%CI ［1.048， 2.369］）， and the independent factors influencing the blood lipid standard of coronary heart disease patients with stable angina （P = 0.011， 95%CI ［1.133， 2.646］）， but not the independent factors affecting blood glucose standard in coronary heart disease patients with diabetes （P＞0.05）. ConclusionCoronary artery disease patients with stable angina have geographical variability in clinical characteristics and distribution of TCM syndrome elements， and the overall control of blood pressure， blood lipids， and blood glucose is poor， and qi deficiency syndrome is an independent risk factor affecting the control of blood pressure and blood lipids.
