Objective:To explore the effect of multiple modified process management intervention on cardiac func-tion,psychological state,stress level,sleep quality and adverse events in patients with severe coronary atherosclerot-ic heart disease(CHD).Methods:This randomized controlled study enrolled 130 severe CHD patients who were treated in Affiliated Beijing Shijitan Hospital of Capital Medical University between January 2020 and May 2023.Patients were randomly divided into control group(n=65)and intervention group(n=65).Patients in the control group were treated with routine management intervention,while those in the intervention group were given addi-tional multiple modified process management interventions.Both groups were intervened for 4 weeks.Cardiac func-tion,levels of norepinephrine(NE)and cortisol(COR),scores of Self-rating Anxiety Scale(SAS),Self-rating Depression Scale(SDS),General Comfort Questionnaire(GCQ),Pittsburgh Sleep Quality Index(PSQI),and the incidence of adverse events during intervention were compared between the two groups.Results:Compared to those in control group after intervention,patients in intervention group had significant higher left ventricular ejection fraction(LVEF)[(57.81±2.15)％vs.(50.11±2.99)％]and GCQ score[(95.88±5.37)points vs.(75.81±6.67)points](P＜0.001 all),and significant lower left ventricular end-diastolic volume(LVEDV)[(109.81±5.37)ml vs.(129.26±5.17)ml],left ventricular end-systolic volume(LVESV)[(50.85±3.08)ml vs.(66.02±3.77)ml],levels of NE[(61.56±5.49)pg/ml vs.(69.86±5.03)pg/ml],COR[(85.63±5.19)ng/ml vs.(92.28±6.57)ng/ml],scores of SAS[(30.06±5.19)points vs.(49.51±5.85)points],SDS[(31.86±4.51)points vs.(40.00±5.10)points]and PSQI[(8.72±1.58)points vs.(13.89±2.40)points],and incidence of ad-verse events(4.69％vs.23.44％)(P＜0.01 all).Conclusion:The multiple modified process management interven-tion may improve the cardiac function,adverse psychological state,stress level,sleep quality and reduce the inci-dence of adverse events in patients with severe CHD.

Objective:This systematic review and meta-analysis aims to evaluate the effect of traditional Chinese medicine(TCM)combined with acupuncture on chronic heart failure(CHF).Methods:CNKI,CBM,VIP,Wanfang database,the Cochrane Library,PubMed and Embase databases were searched for randomized controlled trials that com-pare the clinical efficacy between TCM combined acupuncture therapy and routine western medical treatment on CHF from establishment to July 23rd,2024.Results:A total of 14 studies were included in the final analysis.Compared to patients in control group,those in trial group had significant higher total effective rate[OR=3.84,95％CI(2.58,5.72),P＜0.001]and left ventricular ejection fraction[MD=4.69,95％CI(3.74,5.63),P＜0.001],and significant lower left ventricular end-systolic diameter[MD=-3.35,95％CI(-5.24,-1.46),P＜0.001],left ventricular end-diastolic diameter[MD=-3.54,95％CI(-5.08,-2.00),P＜0.001],levels of N terminal pro brain natriuretic peptide[SMD=-1.72,95％CI(-2.28,-1.15),P＜0.001],high sensitive C reactive protein[MD=-6.73,95％CI(-10.16,-3.31),P＜0.001],tumor necrosis factor-α[SMD=-3.77,95％CI(-6.08,-1.45),P=0.001]and interleukin-6[SMD=-1.52,95％CI(-2.21,-0.82),P＜0.001].Conclusion:Traditional Chinese medicine combined with acupuncture may improve the cardiac structure and function,reduce the level of NT-proBNP,and has a certain effect of inhibiting micro-inflammation in patients with chronic heart failure.

Objective:To explore the relationship between the prognostic nutritional index(PNI)and the prevalence of coronary heart disease(CHD)in adults.Methods:A cross-sectional analysis was conducted based on the 2017-2020 National Health and Nutrition Examination Survey(NHANES)database.A total of 12,141 adult participants were initially included and divided into CHD group and control group according to the disease status questionnaire.PNI was calculated using serum albumin level and lymphocyte count.Multivariable logistic regression was applied to explore the association between PNI and the prevalence of CHD in adults.Subgroup analysis was conducted to assess whether this association remained consistent across different populations.A restricted cubic spline model was con-structed to clarify the dose-response relationship between PNI and CHD prevalence in adults.Results:Among the 3,894 adult participants,200(5.14％)had CHD.The PNI level in CHD patients was significantly lower than that of the control group[(49.20±8.59)vs.(51.57±4.80),P＜0.001].Multivariable logistic regression analysis showed that,after adjustment for sex,age,race,marital status,body mass index(BMI),hypertension,diabetes and family history of cardiovascular disease,an increase in PNI was still independently associated with a lower prev-alence of CHD(odds ratio[OR]=0.92,95％CI 0.89～0.94,P＜0.001).The dose-response relationship indica-ted a negative linear correlation between PNI and CHD prevalence(P＜0.001).Subgroup analysis showed that the association between PNI and CHD differed significantly across BMI,hypertension and diabetes subgroups(P for in-teraction＜0.05 or＜0.01).Conclusion:Increasing PNI was significantly associated with a lower prevalence of CHD in adults,and this association was more pronounced in specific high-risk populations,such as those with obe-sity,hypertension,and diabetes.Our findings suggest that maintaining good nutritional status is of great significance in reducing the risk of CHD.

Objective:To construct a risk prediction model of postoperative severe bradyarrhythmia for patients with valvular heart disease and verify the predictive efficacy of the model.Methods:A total of 636 patients undergoing heart valve surgery in Nanjing First Hospital between June 2023 and March 2024 were retrospectively selected.Ac-cording to the need for permanent pacemaker implantation after the surgery,the patients were divided into severe bradyarrhythmia group(n=80)and non-severe bradyarrhythmia group(n=556),then univariate and multivariate Logistic regression analysis were conducted to analyze the influencing factors of postoperative severe bradyarrhyth-mia in patients with valvular heart disease.R software was used to draw a nomogram prediction model for postoper-ative severe bradyarrhythmia in patients with valvular heart disease,and to verify the predictive effect of the model.Results:The incidence of postoperative severe bradyarrhythmia in patients with valvular heart disease was 12.6％in this study.Multivariate Logistic regression analysis showed that BMI＞28kg/m2(OR=2.094,95％CI 1.047～4.189,P=0.037),preoperative conduction block(OR=6.507,95％CI 2.909～14.552,P＜0.001),tricuspid valve surgery(OR=1.831,95％CI 1.094～3.063,P=0.021)and low cardiac output after surgery(OR=3.186,95％CI 1.310～7.751,P=0.011)were independent risk factors of postoperative severe bradyarrhythmia in these patients,while NYHA class Ⅲ～Ⅳ was its independent protective factor(OR=0.328,95％CI 0.194～0.555,P＜0.001).The nomogram model was constructed based on the influencing factors.H-L test in model group showed that x2=3.667,P=0.886,AUC under ROC curve was 0.744(95％CI 0.685～0.803),H-L test in validation group showed that x2=9.314,P=0.316,AUC under ROC was 0.718(95％CI 0.618～0.818),and the accuracy was 72.0％.Conclusion:The independent predictors for postoperative severe bradyarrhythmia in patients with val-vular heart disease include BMI,preoperative conduction block,NYHA class,tricuspid valve surgery and low cardi-ac output after surgery.A prediction model based on the above-mentioned risk factors may have good performance in predicting postoperative severe bradyarrhythmia in this population.

Objective:To explore the diagnostic efficacy of monocyte chemotactic protein-1(MCP-1)and creatine kinase isoenzyme(CK-MB)for chronic heart failure(CHF)and their association with New York Heart Associa-tion(NYHA)class.Methods:A total of 300 patients suspected of CHF who underwent physical examination in the Second People's Hospital of Hefei between January 2020 and August 2021 were analyzed.After 3-month follow-up,a total of 150 patients were diagnosed with CHF.According to NYHA cardiac function classification,CHF pa-tients were divided into class Ⅱ group(n=45),class Ⅲ group(n=45)and class Ⅳ group(n=60).MCP-1 and CK-MB levels were compared among above groups.Receiver operating characteristic(ROC)curve was used to an-alyze the diagnostic efficacy of each index and their combination for CHF and their association with NYHA class were analyzed using Spearman correlation analysis.Results:Compared to those without CHF,patients with CHF had significant higher levels of MCP-1[96.01(86.21,124.28)ng/ml vs.25.38(22.79,28.72)ng/ml,P＜0.001]and CK-MB[46.26(32.74,59.72)U/L vs.19.09(18.61,19.87)U/L,P＜0.001].ROC curve showed that a combination of MCP-1 and CK-MB had a significant higher area under the ROC curve(AUC)(0.947,95％CI 0.915～0.969)than MCP-1(0.797,95％CI 0.747～0.841)or CK-MB(0.855,95％CI 0.810～0.893)alone(Z=4.543,3.170,P＜0.001 all).Compared to those in the class Ⅱ group,those in the class Ⅲgroup and class Ⅳ group had significant higher MCP-1[94.57(91.18,96.92)ng/ml vs.125.27(123.20,128.24)ng/ml vs.68.38(27.55,86.38)ng/ml]and CK-MB[48.04(45.66,51.47)U/L vs.61.01(58.81,62.96)U/L vs.31.75(25.08,33.57)U/L],and those of class Ⅳ group were significantly higher than those of class Ⅲ group(P＜0.001 all).Spearman correlation analysis indicated that the levels of MCP-1 and CK-MB were significant positively correlated with NYHA class in CHF patients(r=0.712,0.878,P＜0.001 both).Con-clusion:MCP-1 and CK-MB were abnormally elevated in CHF patients.Serum levels of MCP-1 and CK-MB are significantly correlated with NYHA class.The combination had high diagnostic efficacy for CHF.

Objective:To explore the therapeutic effect of drug-coated balloon(DCB)combined drug-eluting stent(DES)on coronary bifurcation lesions.Methods:A total of 108 patients with coronary bifurcation lesions admitted in Shanghai Ninth People's Hospital Huangpu Branch,Shanghai Jiaotong University School of Medicine between February 2021 and March 2023 were enrolled in this randomized controlled study.Patients were randomly divided into combined treatment group(n=54,DCB was implanted in the sub-branch,and DES was implanted in the main branch)and DES group(n=54,DES were implanted in both main branch and sub-branch).Clinical therapeutic effect,coronary angiography quantitative parameters before,instant and 9 months after operation and clinical out-comes during 1-year follow-up after operation were compared between two groups.Results:The total effective rate of combined treatment group was significantly higher than that of DES group(96.30％vs.87.04％,P=0.030).Compared to those in DES group,instant and 9 months after operation,patients in the combined treatment group had significant higher diameters of main branch vessel[(3.13±0.31)mm vs.(3.01±0.25)mm,(2.99±0.33)mm vs.(2.84±0.23)mm],sub-branch vessel[(2.51±0.26)mm vs.(2.42±0.13)mm,(2.44±0.24)mm vs.(2.29±0.36)mm],and significant lower main branch stenosis rate[(6.05±0.21)％vs.(6.24±0.31)％,(9.06±0.23)％vs.(10.12±0.12)％]and sub-branch stenosis rate[(7.38±0.42)％vs.(7.63±0.18)％,(8.07±0.39)％vs.(11.25±0.22)％](P＜0.05 or＜0.01).There were no significant difference in incidence of target lesion revascularization,cardiogenic death and major adverse cardiovascular events between two groups(P＞0.05 all).Conclusion:Drug-eluting stent combined drug-coated balloon may promote vascular branch dilation of coro-nary artery lesions,increase the minimum lumen diameter of sub-branch vessels,and reduce the occurrence of ste-nosis in the treatment of coronary bifurcation lesion,which had similar effectiveness and safety with drug-eluting stent technique.

Objective:To investigate the predictive value of serum cholinesterase(CHE)and soluble growth stimula-tion gene 2 protein(sST2)for short-term death in patients with myocardial infarction and heart failure.Methods:A total of 100 patients with myocardial infarction and heart failure admitted in Nanjing Benq Hospital between March 2021 and March 2023 were screened.After 6-month follow-up,patients were grouped according to pres-ence of death.Multivariate Cox regression was used to analyze the factors associated with death during 6-month follow-up in patients with myocardial infarction and heart failure.The predictive value of CHE,sST2 and their combined detection for short-term death in patients with myocardial infarction and heart failure was analyzed by receiver operating characteristic(ROC)curve.Kaplan-Meier survival curve was used to compare short-term sur-vival rate between myocardial infarction and heart failure patients with different CHE and sST2 levels.Results:During 6-month follow-up,46 cases died.Compared to those in survival group,patients in death group had sig-nificant higher heart rate(HR)[(82.20±8.09)beats/min vs.(71.54±6.97)beats/min],mean arterial pressure(MAP)[(126.58±5.38)mmHg vs.(104.79±4.94)mmHg]and sST2[(76.48±4.82)ng/ml vs.(40.62±4.96)ng/ml],and significant lower CHE[(3.47±0.26)IU/L vs.(5.07±0.80)IU/L](P＜0.001 all).Multivariate Cox regression showed that HR(HR 1.046,95％CI 1.002～1.092,P=0.040),MAP(HR 1.988,95％CI 1.298～2.455,P＜0.001),and sST2(HR 1.068,95％CI 1.014～1.125,P=0.013)were independent risk factors for short-term death in patients with myocardial infarction and heart failure,while CHE was its independent protec-tive factor(HR=0.252,95％CI 0.145～0.561,P=0.023).ROC curve analysis indicated that the area under the curve(AUC)of CHE,sST2 and their combination for diagnosing short-term death in patients with myocardial in-farction and heart failure was 0.609(95％0.504～0.707),0.630(95％0.525～0.726)and 0.939(95％0.871～0.977)respectively,and the diagnostic efficacy of combined detection was significantly higher than CHE and sST2 alone(Z=5.814,5.524,P＜0.001 all).Kaplan-Meier survival curve showed that the survival rate of patients with low CHE level was significantly lower than that of patients with high CHE level,and the survival rate of pa-tients with high sST2 level was significantly lower than that of patients with low sST2 level(Log-rank x2=2.415,2.354,P＜0.001 all).Conclusion:CHE and sST2 were independent influencing factors for death during 6-month follow-up in patients with myocardial infarction and heart failure;their combined detection had good predictive value for short-term death in these patients.

Objective:To explore the effect of horizontal Baduanjin guided by interactive standard reaching theory(ISRT)on cardiac function and quality of life in patients with chronic heart failure(CHF).Methods:This random-ized controlled study enrolled 114 patients diagnosed with CHF in Bozhou People's Hospital between September 2024 and February 2025.Patients were randomly divided into control group(n=57,routine nursing care)and interven-tion group(n=57,horizontal Baduanjin under the guidance of interactive standard theory).Both groups were con-tinuously treated for 3 months.Cardiac function indexes,N-terminal pro-brain natriuretic peptide(NT-proB-NP),self-care ability,quality of life and incidence of major adverse cardiovascular events(MACE)were com-pared between the two groups.Results:Compared to patients in the control group,those in the intervention had significant higher left ventricular ejection fraction(LVEF)[(56.34±0.86)％vs.(46.69±0.91)％],6min walking distance(6MWD)[(477.16±6.62)m vs.(451.39±4.17)m]and the proportion of New York Heart Association(NYHA)class Ⅱ(70.18％vs.35.09％),and significant lower NT-proBNP[(237.76±6.41)pg/ml vs.(377.46±6.85)pg/ml],scores of the European heart failure self-care behavior scale 9(EHFSCB-9)[(12.61±1.81)points vs.(25.51±1.71)points],the physical domain[(3.96±0.91)points vs.(11.05±0.79)points],emotional domain[(4.00±0.85)points vs.(11.95±0.81)points]and other domain[(4.05±0.83)points vs.(13.47±1.15)points]of MLHFQ(P＜0.001 all).Compared to those in the control group,patients in intervention group had significant lower incidence of MACE(7.02％vs.22.81％,P=0.035).Conclusion:Under the guidance of the interactive standard theory,the horizontal Baduanjin exercise may enhance the cardiac function,improve self-care ability and quality of life in patients with chronic heart failure.
