Methods: The Gene Expression Omnibus (GEO) database was used for data retrieval, and the chip data GSE3585 was downloaded, which was the original data of DCM and normal control group. At the same time, the chip data GSE76701 was downloaded, which was the original data of CHF and control group. Differentially expressed mRNAs (DEmRNAs) were screened by R language limma package, the data were standardized, and the common differentially expressed genes were screened. GO function and KEGG pathway enrichment analysis were performed on the common differentially expressed genes. String11.0 online tool was used for data analysis to obtain differentially expressed genes, and the results were imported into Cytoscape 3.9.1 software. The results were imported into Cytoscape 3.9.1 software, and the common expression gene module was obtained by MOCDE algorithm. Nine Hub genes were obtained by 10 algorithms such as MCC. Results: A total of 248 differentially expressed genes were screened. GO analysis showed that differentially expressed genes were mainly concentrated in 9 different physiological and pathological processes. KEGG analysis showed that the main signaling pathways involved in differentially expressed genes were 2, and 9 key differentially expressed genes were predicted: NPPB, NPPA, MYH6, FRZB, ASPN, SFRP4, RPS4Y1, DDX3Y. Conclusion: This study preliminarily explored the molecular mechanism of DCM and CHF, and obtained the common differentially expressed genes of the two diseases. Further experimental studies are needed to verify the correlation between gene expression and clinicopathological features. Provide new ideas for clinical drug treatment research.展开更多

The control group received regular treatment, the observation group received regular + Danhong injection treatment, and both therapies lasted for 14 d a course, two sessions. Serum contents of neuroendocrine molecules and ventricular remodeling-related indexes, Doppler ultrasonic ventricular remodeling parameter levels, and so on were compared between two groups of patients before and after treatment.Results: Before treatment, serum contents of neuroendocrine molecules and ventricular remodeling-related indexes as well as Doppler ultrasonic ventricular remodeling parameter levels were not statistically different between two groups of patients. After treatment, serum neuroendocrine molecules NT-proBNP, ANP, AngⅡ, ALD and NE contents of observation group were lower than those of control group, serum ventricular remodeling indexes TGF-β1, NF-κB, CysC and FGF23 contents were lower than those of control group, and ultrasonic ventricular remodeling parameters LVMI, LVRI, RVEDV and RVESV levels were lower than those of control group.Conclusion: Adjuvant Danhong injection therapy helps optimize the neuroendocrine molecule contents and inhibit the ventricular remodeling process in patients with ischemic cardiomyopathy heart failure.展开更多

In this study, we investigated the association between QT dispersion corrected for heart rate （cQTd） and heart function in patients with CHF. Methods From January 2013 to December 2015, we continuously enrolled 240 patients categorized as New York Heart Association functional class （NYHA） III-IV with a left ventricular ejection fraction （LVEF） 〈 40%. Based on the etiology, the patients were divided into a dilated cardiomyopathy （DCM） group （n = 120） and an ischemic cardiomyopathy （ICM） group （n = 120）. Then, based on the cQTd width, the ICM group was divided into two subgroups： a QS group （cQTd ≤60 ms, n = 70） and a QL group （cQTd 〉 60 ms, n = 50）. All patients were examined by echocardiography and 12-lead electrocardiography （ECG） at 1, 3, 6, and 12 months after enrollment. Results After one year of optimized medical treatment, patients in both groups showed significant improvement in LVEF and NYHA classification from baseline. However, the cQTd in the ICM group, especially the QL, was significantly shorter than that in the DCM group at each time point. In addition, the cQTd was negatively correlated with LVEF and 6-min walking test and positively correlated with NYHA class in the ICM group. Conclusions The present findings clearly demonstrate that cQTd is a meaningful parameter for assessing heart function in the follow-up of ICM patients.展开更多

All patients un-derwent a symptom limited cardiopulmonary exercise testing on a cycle-ergometer, in order to access CHF severity. A multivariate linear regression analysis us-ing simultaneous entry of predictors was performed to examine which of the CHF variables and of the person-ality variables were correlated independently to QoL scores in the two summary scales of the KCCQ, namely the Overall Summary Scale and the Clinical Summary Scale.RESULTS: The Neuroticism personality trait score had a significant inverse correlation with the Clinical Sum-mary Score and Overall Summary Score of the KCCQ(r =-0.621, P < 0.05 and r =-0.543, P < 0.001, respec-tively). KCCQ summary scales did not show significant correlations with the personality traits of Extraversion, Openness, Conscientiousness and Agreeableness. Mul-tivariate linear regression analysis using simultaneous entry of predictors was also conducted to determine the best linear combination of statistically significant univari-ate predictors such as Neuroticism, VE/VCO2 slope and VO2 peak, for predicting KCCQ Clinical Summary Score. The results show Neuroticism(β =-0.37, P < 0.05), VE/VCO2 slope(β =-0.31, P < 0.05) and VO2 peak(β = 0.37, P < 0.05) to be independent predictors of QoL. In multivariate regression analysis Neuroticism(b =-0.37, P < 0.05), the slope of ventilatory equivalent for carbon dioxide output during exercise,(VE/VCO2 slope)(b =-0.31, P < 0.05) and peak oxygen uptake(VO2 peak),(b = 0.37, P < 0.05) were independent predictors of QoL(adjusted R2 = 0.64; F = 18.89, P < 0.001).CONCLUSION: Neuroticism is independently associat-ed with QoL in CHF. QoL in CHF is not only determined by disease severity but also by the Neuroticism person-ality trait.展开更多

Hypoglycemia can potentially lead to worsening of cardiac function in patients with ischemic heart disease. We present a case of cardiogenic shock in a patient with hypoglycemia secondary to insulin accumulation due to worsening renal function with dramatic recovery of shock once his sugars normalized.展开更多
