ABSTRACT
Resumen Introducción: Las enfermedades coronarias son una de las principales causas de muerte en todo el mundo. El tratamiento para la enfermedad coronaria puede ser farmacológico y no farmacológico. Cuando el diagnóstico es reciente, los pacientes inician un proceso adaptativo y con esto hay posibilidad de desarrollar síntomas depresivos. Objetivo: Identificar la prevalencia de síntomas depresivos y factores asociados al inicio del programa de rehabilitación cardíaca en pacientes con enfermedad coronaria en una institución de salud. Materiales y método: Estudio transversal analítico, en 95 pacientes con enfermedad coronaria que iniciaron el programa de rehabilitación cardíaca. Se analizaron datos sociodemográficos, factores de riesgo cardiovascular y actividad física. Los puntajes de la subescala de síntomas depresivos fueron medidos con DASS-21. Se estimaron prevalencias y razones de prevalencia mediante modelos de regresión de Poisson con varianza robusta, con niveles de confianza del 95%. Resultados: El 70.5% de los pacientes que iniciaron el programa presentaron síntomas depresivos. El régimen de salud (RP: 0.75; IC 95%: 0.60-0.94; p = 0.013), el riesgo cardiovascular (RP: 0.62; IC 95%: 0.50-0.77; p < 0.001) y la esternotomía previa (IC 95%: 1.01-1.62; p = 0.040) son factores asociados para síntomas depresivos en estos pacientes. Conclusiones: Siete de cada diez pacientes con enfermedad coronaria que iniciaron el programa, presentaron síntomas depresivos.
Abstract Introduction: Coronary heart disease is one of the leading causes of death worldwide (1). Treatment for coronary disease is pharmacological and non-pharmacological. When the diagnosis is recent, patients begin an adaptive process and with this the possibility of developing depressive symptoms. Objective: To identify the prevalence of depressive symptoms and factors associated with presenting these symptoms at the beginning of the cardiac rehabilitation program in patients with coronary disease in a health institution. Materials and method: Analytical cross-sectional study in 95 patients with coronary disease who started the cardiac rehabilitation program. Sociodemographic data, cardiovascular risk factors, physical activity, and depressive symptoms subscale scores were measured with the DASS-21. Prevalence and prevalence ratios were estimated using Poisson regression models with robust variance, with confidence levels of 95%.

Abstract Introduction: To characterize the population of patients hospitalized for acute heart failure with an ejection fraction of less than 50% in the Departmental Hospital of Villavicencio. Materials and method: This is a descriptive retrospective cohort study of patients hospitalized for acute heart failure with an ejection fraction (LVEF) of less than 50% between January 1, 2020, and December 31, 2021. Results: A total of 206 participants were included, with a median age of 70 years, of the participants, 71.8% were men, the most frequent comorbidities were hypertension (76.2%), coronary disease (47.1%), and diabetes (32%). The main etiologies of heart failure were ischemic (62.1%) and hypertensive (27.2%), with 6.8% attributed to Chagas disease. The most common causes of decompensation were acute coronary syndrome (39.3%) and poor adherence to treatment (25.7%). The median hospital stay was 7.5 days, and the hospital mortality rate was 14.6%, acute coronary syndrome was the leading cause of death (56.7%). A high requirement for intensive care unit (ICU) management was observed (20.4%), which was higher in patients with slightly reduced LVEF compared to those with reduced LVEF (35.7% vs. 18%, RR = 1.98, p = 0.03), however, the mortality rate was similar between both groups (17.9% vs. 14%, RR = 1.32, p = 0.54). Conclusions: It was found a high prevalence of ischemic heart disease, along with a high requirement for ICU management and high in-hospital mortality.

ABSTRACT
Objective:To predict Chinese materia medica that may prevent and treat coronary microvascular dysfunction (CMD) by identifying disease core targets.Methods:CMD- related targets were obtained through GeneCards and OMIM databases. Subnetworks were extracted by using MCODE plugin in Cytoscape 3.9.1. Core targets of subnetworks were obtained by using cytoNCA plugin. GO function and KEGG pathway enrichment analysis for core targets were performed by using Metascape. Coremine Medical database was used to match targets with Chinese materia medica. Obtained Chinese materia medica was screened, and their properties and tastes, meridians and efficacy categories were under statistics.Results:Totally 3 859 disease-related targets were screened and five subnetworks were obtained. An in-depth study of MCODE1 yielded ten core targets, including IL-1β, IL6, TNF, STAT3, AKT1, ACTB, VEGFA, GAPDH, TP53, and ALB. GO functional enrichment analysis showed that these core targets were mainly involved in biological processes, such as positive regulation of gene expression, positive regulation of transcription, DNA template, and negative regulation of gene expression. KEGG pathway enrichment analysis identified 67 signaling pathways, including the AGEs-RAGE signaling pathway, HIF-1 signaling pathway, adipocytokine signaling pathway, fluid shear stress, and atherosclerosis. The researchers identified 36 kinds of Chinese materia medica associated with the ten core targets, including Salviea Miltiorrhizae Radix et Rhizoma, Chuanxiaong Rhizoma, Carthami Flos, Paeoniae Radix Rubra, Coptidis Rhizoma, Ginseng Radix et Rhizoma, Ophiopogonis Radix, Schisandrae Chinensis Fructus, Cinnamomi Cortex, Nelumbinis Semen, and Valerianae Jatamansi Rhizoma et Radix among 880 herbs.Conclusion:This study predicts 36 kinds of Chinese materia medica that have the effect of preventing and treating CMD, which can provide research ideas for the development of new drugs.
ABSTRACT
Objective:With the help of SWOT(S: internal strengths, W: internal weaknesses, O: external opportunities, T: external threats)analysis, to explore the internal and external conditions of internet-based cognitive behavioral therapy applied to improve the negative emotions of patients with coronary heart disease, and to propose development strategies.Methods:SWOT analysis was used to analyze and sort out the internal strengths and internal weaknesses, external opportunities and external threats of internet-based cognitive behavioral therapy in improving the negative emotions of patients with coronary heart disease.Results:The internal strengths of internet-based cognitive behavioral therapy in improving the negative emotions of patients with coronary heart disease were significant therapeutic effect, strong operability and high cost-effectiveness. The internal weaknesses included excessive dependence on patients′ treatment enthusiasm, and a lack of psychological training among nurses. The external opportunities included demand support, technical support, and theoretical support. The external threats were the lack of large-scale empirical research and the risk of patient personal information leakage.Conclusions:In the clinical application of internet-based cognitive behavioral therapy to improve the negative emotions of patients with coronary heart disease, both strengths and weaknesses coexist, and opportunities and threats coexist. Only by taking strengths of opportunities to overcome weaknesses, improve the autonomy and enthusiasm of patients in treatment, and increase the psychological training of medical staff, can internet-based cognitive behavioral therapy be further promoted in the clinical application of improving the negative emotions of patients with coronary heart disease.

ABSTRACT
Objective:To investigate the value of peripheral blood platelet to gamma-glutamyl transferase ratio (PLT/GGT) in evaluating plaque stability recognized by virtual histology-intravascular ultrasound (VH-IVUS) in patients with coronary heart disease.Methods:This study was a prospective study. A total of 100 patients with coronary heart disease admitted in Zhejiang Veteran Hospital/the Third Affiliated Hospital of Jiaxing University from June 2020 to December 2022 were included. They were divided into vulnerable plaque group (42 cases) and stable plaque group (58 cases) based on the stability of the plaque examined by VH-IVUS. The general data, PLT/GGT and other laboratory indexes were compared between the two groups. The relationship between PLT/GGT and plaque stability in peripheral blood of patients with coronary heart disease and the evaluation value of PLT/GGT on plaque stability were analyzed.Results:The levels of C-reactive protein (CRP) and gamma-glutamyl transferase (GGT) in the vulnerable plaque group were higher than those in the stable plaque group: (8.07 ± 1.85) mg/L vs. (7.23 ± 1.57) mg/L, (72.39 ± 10.85) U/L vs. (67.13 ± 8.57) U/L, and PLT, PLT/GGT levels were lower than those in the stable plaque group: (180.76 ± 11.75) × 10 9/L vs. (187.36 ± 12.47) × 10 9/L, 2.55 ± 0.42 vs. 2.84 ± 0.41, the differences were statistically significant ( P<0.05). Point two column correlation found that the plaque stability recognized by VH-IVUS in patients with coronary heart disease was related to CRP, GGT, PLT, PLT/GGT ( P<0.05). Receiver operating characteristic curve analysis showed that the area under the curve (AUC) for assessing plaque stability using the peripheral blood PLT/GGT in patients with coronary heart disease was 0.71, which had certain evaluation value. Conclusions:The peripheral blood PLT/GGT in patients with coronary heart disease is closely related to the plaque stability recognized by VH-IVUS, and can be used as an effective indicator for evaluating plaque stability in patients.
ABSTRACT
Objective:To investigate the efficacy of trimetazidine in the treatment of atrial arrhythmias in patients with ischemic cardiomyopathy and heart failure and analyze the effect of trimetazidine on cardiac function and atrial arrhythmias.Methods:A total of 79 patients with ischemic cardiomyopathy and heart failure who received treatment at the Second Hospital of Jiaxing from December 2018 to June 2020 were included in this study. These patients were randomly divided into an observation group ( n = 41) and a control group ( n = 38). Patients in the control group received conventional drugs, while those in the observation group received trimetazidine sustained-release tablets twice daily, each time taking 35 mg in addition to conventional drugs. The treatment lasted for 24 weeks. Before and after treatment, cardiac function indicators (left ventricular ejection fraction, B-type brain natriuretic peptide, 6-minute walking distance), cardiac color Doppler ultrasound indicators [ratio of early to late peak filling rate (E/A ratio)], left ventricular fractional shortening), electrocardiogram parameters (maximum P-wave duration, minimum P-wave duration, and P-wave dispersion), dynamic electrocardiogram parameters [number of single atrial premature beats, total number and duration of paroxysmal atrial tachycardia episodes, total number and duration of paroxysmal atrial flutter/fibrillation attacks, standard deviation of RR intervals, root mean square of successive differences between normal heartbeats, proportion of successive RR intervals that differ by more than 50 ms divided by the total number of NN intervals (PNN50), standard deviation of average NN intervals, high frequency and low frequency], as well as changes in high sensitivity C-reactive protein were analyzed in each group. Results:After treatment, left ventricular ejection fraction, B-type brain natriuretic peptide, 6-minute walking distance, maximum P-wave duration, P-wave dispersion, total number of atrial flutter/atrial fibrillation attacks, and duration of atrial flutter/atrial fibrillation in the observation group were (51.05 ± 7.68)%, (1 615.59 ± 1 129.78) ng/L, (350.02 ± 62.99) m, (99.73 ± 11.60) ms, (22.44 ± 12.03) ms, (0.22 ± 0.61), and (4.59 ± 12.30) minutes, respectively, which were significantly superior to (46.82 ± 7.34)%, (2 267.47 ± 1 539.03) ng/L, (294.16 ± 58.20) m, (111.71 ± 10.00) ms, (36.77 ± 15.07) ms, (0.76 ± 1.13), (15.66 ± 22.30) minutes in the control group, t = -2.95, 2.16, -4.08, 4.89, 4.68, 2.69, 2.76, all P < 0.01). Conclusion:Trimetazidine can effectively reduce atrial arrhythmias and improve the prognosis of patients with ischemic cardiomyopathy and heart failure, which warrants clinical promotion.
ABSTRACT
Objective:To evaluate the correlation and consistency between quantitative coronary flow fraction (QFR) and cardiac magnetic resonance imaging (CMR) in assessing myocardial ischemia in patients with coronary heart disease (CAD).Methods:A retrospective analysis was conducted on the data of coronary heart disease patients who underwent load CMR examination and coronary angiography at the Beijing Anzhen Hospital, Capital Medical University from August 2017 to March 2022. CMR examination includes cardiac cine, load/rest myocardial perfusion imaging, and delayed enhancement sequence. According to the results of CMR examination, the patient′s left ventricular myocardial segments were divided into normal segment group and abnormal segment group (further divided into ischemic segment group and infarcted segment group). On the basis of coronary angiography, an artificial intelligence based platform (AngioPlus system) was applied to calculate the preoperative coronary artery QFR value of patients undergoing percutaneous coronary intervention treatment. Kappa test was used to evaluate the consistency of QFR and CMR in diagnosing abnormal myocardium; Mann Whitney U test was used to compare the differences in QFR between groups; The receiver operating characteristic (ROC) curve was used to evaluate the efficacy of QFR in diagnosing abnormal myocardium; Spearman correlation analysis was used to clarify the relationship between myocardial infarction area and QFR value of the supplying coronary artery in patients.Results:Among the 70 CAD patients enrolled, there were 60 males and 10 females, aged (54.1±11.1)years. At the vascular level, the consistency between QFR and CMR in diagnosing myocardial injury (including ischemia and infarction) is moderate (Kappa value=0.514). The sensitivity and specificity of detecting abnormal myocardial segments in CAD patients were 57% and 91%, respectively. The area under the curve (AUC) value of QFR predicting abnormal myocardium in CAD patients was 0.769, and the optimal cutoff value was QFR=0.865. At this time, the sensitivity and specificity of QFR predicting myocardial injury in CAD patients were 67.2% and 84.3%, respectively. The difference in vascular QFR between the normal segment group, ischemic segment group, and infarcted segment group was statistically significant ( P<0.001), with the infarcted segment group having significantly lower QFR values than the other two groups (all P<0.01). The range of myocardial infarction was negatively correlated with the QFR value of the supplying coronary artery ( r=-0.45, P<0.001). At the patient level, the consistency between QFR and CMR in diagnosing myocardial injury (including ischemia and infarction) was moderate (Kappa value=0.445), with a sensitivity of 74% and a specificity of 81% for diagnosing myocardial injury in CAD patients. Conclusions:Compared with CMR, QFR has better specificity in detecting myocardial injury in CAD patients. The QFR value of the infarcted segment group is significantly lower than that of the ischemic group and the normal group. The area of myocardial infarction is negatively correlated with the QFR value of the supplying coronary artery.
ABSTRACT
Objective:To explore the relationship between changes in levels of thrombomodulin (TM) and non high-density lipoprotein cholesterol (non-HDL-C) with ascending aortic elastic function and degree of coronary artery disease (CHD) in patients with coronary heart disease (CHD).Methods:A total of 147 patients with coronary heart disease diagnosed through coronary angiography at Yulin First Hospital from January 2018 to December 2022 were selected as the CHD group. In addition, 90 volunteers who underwent health examinations at our hospital and did not experience coronary artery disease were selected as the control group. Two groups were compared in terms of blood lipids [triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C)], ascending aortic elastic function parameters [arterial dilation (AD), arterial stiffness index (ASI)], TM, non HDL-C levels, and other indicators, and stratified analysis was conducted according to the number of coronary lesions. The linear correlation analysis method was used to analyze the relationship between TM, non-HDL-C, Gensini score, and ascending aortic elastic function parameters.Results:The serum levels of TG, TC, LDL-C, TM, and non HDL-C in the CHD group were significantly higher than those in the control group, while the HDL-C levels were lower than those in the control group, with statistical significance (all P<0.05). The ASI of the ascending aorta in the CHD group was significantly higher than that in the control group, while the AD was lower than that in the control group, and the differences were statistically significant (all P<0.05). The serum levels of TG, TC, LDL-C, TM, and non HDL-C in CHD patients with multiple coronary artery lesions were significantly higher than those in patients with dual or single coronary artery lesions, and the HDL-C levels were lower than those in patients with dual or single coronary artery lesions, with statistical significance (all P<0.05); The serum levels of TM and non HDL-C in CHD patients with dual coronary artery disease were significantly higher than those in single coronary artery disease patients, and the HDL-C levels were lower than those in single coronary artery disease patients, with statistical significance (all P<0.05). The ASI of CHD patients with multiple coronary artery lesions was significantly higher than that of patients with dual or single coronary artery lesions, and the AD was lower than that of patients with dual or single coronary artery lesions, with statistical significance (all P<0.05); The ASI of CHD patients with dual coronary artery disease was significantly higher than that of patients with single coronary artery disease, and the AD was lower than that of patients with single coronary artery disease, with statistical significance (all P<0.05). The TM, non HDL-C levels in CHD patients were significantly negatively correlated with AD (all P<0.05), and positively correlated with ASI and Gensini scores (all P<0.05). Conclusions:The levels of TM and non HDL-C in CHD patients significantly increase, and the ascending aortic elasticity function was decreased. TM and non HDL-C are related to coronary elasticity function and the severity of coronary artery disease.
ABSTRACT
Objective To observe characteristics of atherosclerotic plaque of coronary heart disease(CHD)with different traditional Chinese medicine(TCM)syndrome type based on intravenous ultrasound(IVUS).Methods Data of 116 CHD patients were retrospectively analyzed.The patients were divided into syndrome of blood stasis due to qi deficiency(n=33),syndrome of blockade of phlegm-turbidity(n=42)as well as syndrome of intermin-gled phlegm and blood stasis(n=41)according to TCM syndrome differentiation.IVUS was performed to compare lesion vessel and plaque characteristics among different syndromic types of CHD.Results The lipid pool area,extravascular elastic membrane area,remodeling index,plaque eccentricity index of CHD with syndrome of blood stasis due to qi deficiency were all larger than those of syndrome of blockade of phlegm-turbidity as well as syndrome of intermin-gled phlegm and blood stasis(all P<0.05).The proportion of fibrous-fatty within plaques of syndrome of blood stasis due to qi deficiency was bigger than that of syndrome of intermin-gled phlegm and blood stasis(P<0.05).The lipid pool area,extravascular elastic membrane area and plaque eccentricity index of CHD of syndrome of blockade of phlegm-turbidity were smaller than,while the proportion of necrotic core within plaques was bigger than those of syndrome of intermin-gled phlegm and blood stasis(all P<0.05).Conclusion Atherosclerotic plaque characteristics in CHD with different TCM syndrome types were different,and the plaque stability of syndrome of blood stasis due to qi deficiency was the worst.
ABSTRACT
Objective:To investigate the clinical value of multiparametric myocardial imaging using a dual-layer detector spectral CT in the non-invasive preoperative assessment of patients with coronary atherosclerotic heart disease (CHD) undergoing percutaneous coronary intervention (PCI).Methods:The clinical and imaging data of 90 patients who underwent coronary CT angiography (CCTA) with dual-layer spectral detector CT and invasive coronary angiography (ICA) within 30 days at the Affiliated Changshu Hospital of Nantong University from January 2021 to October 2022 were retrospectively analyzed. A total of 189 coronary arteries were included in the study cohort. The patients were divided into PCI ( n=44) and non-PCI groups ( n=46) according to whether they received PCI after evaluation with ICA. The diameter stenosis rate of the coronary arteries, myocardial iodine concentration (IC) and effective atomic number (Z eff) values were obtained from CCTA conventional and spectral images. The IC values and Z eff values of the myocardium in the areas with abnormal perfusion were compared with those in the areas with normal perfusion. The diagnostic performance of these parameters, as well as their combined model, was evaluated and compared using receiver operating characteristic (ROC) curve and area under the curve (AUC) in the pre-PCI assessment of patients with CHD. Results:Baseline patient data did not show statistically significant differences between the PCI and non-PCI groups (all P>0.05). There were statistically significant differences in IC values [(0.42±0.28) and (2.26±0.48) mg/ml] and Z eff values (7.39±0.33 and 8.50±0.25) between the myocardium areas with abnormal perfusion and the myocardium areas with normal perfusion in all patients (all P<0.001). The AUC for assessing whether patients with CHD need PCI treatment using myocardial IC and Z eff values were 0.865 and 0.853, respectively, which were significantly higher than assessment based only on lumen diameter stenosis rate (AUC=0.726, P<0.001). Conclusions:The IC and Z eff derived from myocardial spectral images can be used to diagnose myocardial perfusion abnormalities in patients with CHD. The spectral myocardial multi-parameters imaging shows promising potentials in pre-PCI assessment of patients with CHD, which can improve the efficiency of evaluation and may help to avoid unnecessarily invasive procedures.
ABSTRACT
Objective To investigate the protective and treatment role of ulinastatin(UTI)on con-trast-induced acute kidney injury(CIAKI)in the elderly with coronary heart disease(CHD)and chronic kidney diseases(CKD).Methods A total of 321 elderly CHD inpatients complicated with CKD undergoing coronary angiography admitted in the First Medical Center of Chinese PLA Gen-eral Hospital from November 2021 to November 2022 were enrolled consecutively and then divid-ed into UTI group(n=161)and hydration group(n=160).Their cardiac and renal function pa-rameters were collected and analyzed before and 2 d after intervention.The changes in above pa-rameters and incidence of CIAK were observed and compared between the two groups.Results In 2 d after intervention,the UTI group had significantly lower Scr,urea,CysC,homocysteine and NT-proBNP,but higher eGFR than the hydration group(P<0.01).There were 62 patients(62/321,19.3%)developing CIAKI,including 17 from the UTI group and 45 from the hydration group,and statistical difference was observed in the incidence(10.6%vs 28.1%,P<0.01).For the patients with comorbidities of hypertension,diabetes,hyperlipidemia and hyperuricemia,the incidence of CIAKI was obviously lower in the UTI group than the hydration group(P<0.01).Multivariate logistic regression analysis showed that UTI was an independent protective factor for occurrence of CIAKI(OR=0.348,95%CI:0.180-0.673,P=0.001).Conclusion UTI can im-prove renal function and reduce the risk of CIAKI in elderly CHD patients with CKD.
ABSTRACT
Objective To explore the efficacy and safety of enhanced external counterpulsation(EECP)in elderly patients with acute ischemic stroke(AIS)complicated by coronary heart dis-ease(CHD).Methods A total of 65 AIS patients with CHD admitted in our hospital from Janu-ary to June 2023 were recruited and randomly divided into a control group(drug secondary pre-vention,n=32)and a treatment group(drug combined with EECP therapy,n=33).Their NIHSS score,mRS score and Canadian Cardiovascular Society(CCS)angina grade were evaluated before and after treatment and compared between the two groups.The incidences of recurrent ischemic stroke,new hemorrhagic stroke and major adverse cardiovascular events(MACE)were also recor-ded during treatment.Results The NIHSS score and mRS score were significantly decreased in both groups after treatment(P<0.01).After treatment,the NIHSS score(2.67±1.63 vs 3.56± 1.83),mRS score[1.0(0.0,1.0)vs 2.0(1.0,2.0)]and CCS grade[1.0(1.0,2.0)vs 2.0(1.0,2.0)]were obviously lower in the treatment group than the control group(P<0.05,P<0.01).There were no statistical differences in the incidence rates of recurrent ischemic stroke,new-onset hem-orrhagic stroke,and MACE between the control group and the treatment group(9.4%vs 6.1%,6.3%vs 3.0%,12.5%vs 6.1%,P>0.0 5).Conclusion EECP is a safe and effective treatment option for elderly AIS patients with CHD.
