Dyssynchronous heart failure models in canines:New insights into electrocardiographic,echocardiographic and histological features

Background:We investigated the similarities and differences between two experi-mental approaches using tachy-pacing technology to induce desynchronized heart failure in canines.Methods:A total of eight dogs were included in the experiment,four were tachy-paced in right ventricle apex(RVAP)and 4 were paced in right atrium after the ablation of left bundle branch to achieve left bundle branch block(RAP+LBBB).Three weeks of follow-up were conducted to observe the changes in cardiac function and myocar-dial staining was performed at the end of the experiment.Results:Both experimental approaches successfully established heart failure with reduced ejection fraction models,with similar trends in declining cardiac function.The RAP+LBBB group exhibited a prolonged overall ventricular activation time,de-layed left ventricular activation,and lesser impact on the right ventricle.The RVAP approach led to a reduction in overall right ventricular compliance and right ventricu-lar enlargement.The RAP+LBBB group exhibited significant reductions in left heart compliance(LVGLS,%:RAP+LBBB−12.60±0.12 to−5.93±1.25;RVAP−13.28±0.62 to−8.05±0.63,p=0.023;LASct,%:RAP+LBBB−15.75±6.85 to−1.50±1.00;RVAP−15.75±2.87 to−10.05±6.16,p=0.035).Histological examination revealed more pronounced fibrosis in the left ventricular wall and left atrium in the RAP+LBBB group while the RVAP group showed more prominent fibrosis in the right ventricular myocardium. Conclusion : Both approaches establish HFrEF models with comparable trends. The RVAP group shows impaired right ventricular function, while the RAP+LBBB group exhibits more severe decreased compliance and fibrosis in left ventricle.

Potential preservative mechanisms of cardiac rehabilitation pathways on endothelial function in coronary heart disease

Cardiac rehabilitation,a comprehensive exercise-based lifestyle and medical management,is effective in decreasing morbidity and improving life quality in patients with coronary heart disease.Endothelial function,an irreplaceable indicator in coronary heart disease progression,is measured by various methods in traditional cardiac rehabilitation pathways,including medicinal treatment,aerobic training,and smoking cessation.Nevertheless,studies on the effect of some emerging cardiac rehabilitation programs on endothelial function are limited.This article briefly reviewed the endothelium-beneficial effects of different cardiac rehabilitation pathways,including exercise training,lifestyle modification and psychological intervention in patients with coronary heart disease,and related experimental models,and summarized both uncovered and potential cellular and molecular mechanisms of the beneficial roles of various cardiac rehabilitation pathways on endothelial function.In exercise training and some lifestyle interventions,the enhanced bioavailability of nitric oxide,increased circulating endothelial progenitor cells(EPCs),and decreased oxidative stress are major contributors to preventing endothelial dysfunction in coronary heart disease.Moreover,the preservation of endothelial-dependent hyperpolarizing factors and inflammatory suppression play roles.On the one hand,to develop more endothelium-protective rehabilitation methods in coronary heart disease,adequately designed and sized randomized multicenter clinical trials should be advanced using standardized cardiac rehabilitation programs and existing assessment methods.On the other hand,additional studies using suitable experimental models are warranted to elucidate the relationship between some new interventions and endothelial protection in both macro-and microvasculature.

Glycemic Control and Diabetes Duration in Relation to Subsequent Myocardial Infarction among Patients with Coronary Heart Disease and Type 2 Diabetes

Objective This study aimed to investigate the impact of glycemic control and diabetes duration on subsequent myocardial infarction(MI)in patients with both coronary heart disease(CHD)and type 2 diabetes(T2D).Methods We conducted a retrospective cohort study of 33,238 patients with both CHD and T2D in Shenzhen,China.Patients were categorized into 6 groups based on baseline fasting plasma glucose(FPG)levels and diabetes duration(from the date of diabetes diagnosis to the baseline date)to examine their combined effects on subsequent MI.Cox proportional hazards regression models were used,with further stratification by age,sex,and comorbidities to assess potential interactions.Results Over a median follow-up of 2.4 years,2,110 patients experienced MI.Compared to those with optimal glycemic control(FPG<6.1 mmol/L)and shorter diabetes duration(<10 years),the fullyadjusted hazard ratio(HR)(95%Confidence Interval[95%CI])for those with a diabetes duration of≥10 years and FPG>8.0 mmol/L was 1.93(95%CI:1.59,2.36).The combined effects of FPG and diabetes duration on MI were largely similar across different age,sex,and comorbidity groups,although the excess risk of MI associated with long-term diabetes appeared to be more pronounced among those with atrial fibrillation.Conclusion Our study indicates that glycemic control and diabetes duration significant influence the subsequent occurrence of MI in patients with both CHD and T2D.Tailored management strategies emphasizing strict glycemic control may be particularly beneficial for patients with longer diabetes duration and atrial fibrillation.

BACKGROUND Congenital heart disease is most commonly seen in neonates and it is a major cause of pediatric illness and childhood morbidity and mortality.AIM To identify and build the best predictive model for predicting cyanotic and acyanotic congenital heart disease in children during pregnancy and identify their potential risk factors.METHODS The data were collected from the Pediatric Cardiology Department at Chaudhry Pervaiz Elahi Institute of Cardiology Multan,Pakistan from December 2017 to October 2019.A sample of 3900 mothers whose children were diagnosed with identify the potential outliers.Different machine learning models were compared,and the best-fitted model was selected using the area under the curve,sensitivity,and specificity of the models.RESULTS Out of 3900 patients included,about 69.5%had acyanotic and 30.5%had cyanotic congenital heart disease.Males had more cases of acyanotic(53.6%)and cyanotic(54.5%)congenital heart disease as compared to females.The odds of having cyanotic was 1.28 times higher for children whose mothers used more fast food frequently during pregnancy.The artificial neural network model was selected as the best predictive model with an area under the curve of 0.9012,sensitivity of 65.76%,and specificity of 97.23%.CONCLUSION Children having a positive family history are at very high risk of having cyanotic and acyanotic congenital heart disease.Males are more at risk and their mothers need more care,good food,and physical activity during pregnancy.The best-fitted model for predicting cyanotic and acyanotic congenital heart disease is the artificial neural network.The results obtained and the best model identified will be useful for medical practitioners and public health scientists for an informed decision-making process about the earlier diagnosis and improve the health condition of children in Pakistan.

Mediating function of heart failure in the causal relationship between diastolic blood pressure and hypertensive renal disease with renal failure:a mediated Mendelian randomization study

Objective:To study the causality relationship between diastolic blood pressure(DBP)and hypertensive renal disease with renal failure(HRDRF)and the mediating role of hear t failure(HF)in the causality relationship by network Mendelian randomization(MR).Methods:Genome-wide analysis of DBP,HRDRF,and HF was downloaded from the public database(Genome-Wide Analysis Study[GWAS])and was used to analyze the results and to conduct mediated MR analysis.Results:Analysis showed that DBP was positively correlated with HRDRF(OR=1.0002,95%CI:1.0001–1.0003,P=1.8076e-05)and DBP was positively correlated with HF(OR=1.0295,95%CI:1.0221–1.0370,P=2.5292e-15).HF and HRDRF had a positive causal effect(OR=1.0001,95%CI:1.0000–1.0001,P=0.0152).Mediation analysis showed that the contribution ratio of HF to the combined effect of DBP and HRDRF was 24.69%.Conclusions:DBP can increase the risk of renal disease with renal failure,and HF may play an impor tant role in mediating this causal relationship.

Serum cystatin C,monocyte/high-density lipoprotein-C ratio,and uric acid for the diagnosis of coronary heart disease and heart failure

BACKGROUND Coronary heart disease(CHD)and heart failure(HF)are the major causes of morbidity and mortality worldwide.Early and accurate diagnoses of CHD and HF are essential for optimal management and prognosis.However,conventional diagnostic methods such as electrocardiography,echocardiography,and cardiac biomarkers have certain limitations,such as low sensitivity,specificity,availability,and cost-effectiveness.Therefore,there is a need for simple,noninvasive,and reliable biomarkers to diagnose CHD and HF.AIM To investigate serum cystatin C(Cys-C),monocyte/high-density lipoprotein cholesterol ratio(MHR),and uric acid(UA)diagnostic values for CHD and HF.METHODS We enrolled 80 patients with suspected CHD or HF who were admitted to our hospital between July 2022 and July 2023.The patients were divided into CHD(n=20),HF(n=20),CHD+HF(n=20),and control groups(n=20).The serum levels of Cys-C,MHR,and UA were measured using immunonephelometry and an enzymatic method,respectively,and the diagnostic values for CHD and HF were evaluated using receiver operating characteristic(ROC)curve analysis.RESULTS Serum levels of Cys-C,MHR,and UA were significantly higher in the CHD,HF,and CHD+HF groups than those in the control group.The serum levels of Cys-C,MHR,and UA were significantly higher in the CHD+HF group than those in the CHD or HF group.The ROC curve analysis showed that serum Cys-C,MHR,and UA had good diagnostic performance for CHD and HF,with areas under the curve ranging from 0.78 to 0.93.The optimal cutoff values of serum Cys-C,MHR,and UA for diagnosing CHD,HF,and CHD+HF were 1.2 mg/L,0.9×10^(9),and 389μmol/L;1.4 mg/L,1.0×10^(9),and 449μmol/L;and 1.6 mg/L,1.1×10^(9),and 508μmol/L,respectively.CONCLUSION Serum Cys-C,MHR,and UA are useful biomarkers for diagnosing CHD and HF,and CHD+HF.These can provide information for decision-making and risk stratification in patients with CHD and HF.

Current concept in the diagnosis,treatment and rehabilitation of patients with congestive heart failure

Heart failure(HF)is a major public health problem with a prevalence of 1%-2%in developed countries.The underlying pathophysiology of HF is complex and as a clinical syndrome is characterized by various symptoms and signs.HF is classified according to left ventricular ejection fraction(LVEF)and falls into three groups:LVEF≥50%-HF with preserved ejection fraction(HFpEF),LVEF<40%-HF with reduced ejection fraction(HFrEF),LVEF 40%-49%-HF with mid-range ejection fraction.Diagnosing HF is primarily a clinical approach and it is based on anamnesis,physical examination,echocardiogram,radiological findings of the heart and lungs and laboratory tests,including a specific markers of HF-brain natriuretic peptide or N-terminal pro-B-type natriuretic peptide as well as other diagnostic tests in order to elucidate possible etiologies.Updated diagnostic algorithms for HFpEF have been recommended(H2FPEF,HFA-PEFF).New therapeutic options improve clinical outcomes as well as functional status in patients with HFrEF(e.g.,sodium-glucose cotransporter-2-SGLT2 inhibitors)and such progress in treatment of HFrEF patients resulted in new working definition of the term“HF with recovered left ventricular ejection fraction”.In line with rapid development of HF treatment,cardiac rehabilitation becomes an increasingly important part of overall approach to patients with chronic HF for it has been proven that exercise training can relieve symptoms,improve exercise capacity and quality of life as well as reduce disability and hospitalization rates.We gave an overview of latest insights in HF diagnosis and treatment with special emphasize on the important role of cardiac rehabilitation in such patients.

Health Systems Strengthening to Tackle the Global Burden of Pediatric and Congenital Heart Disease: A Diagonal Approach

1 Background Congenital heart disease(CHD)is the most common major congenital anomaly,affecting approximately one in every 100 live births[1].Among congenital anomalies,66%of preventable deaths are due to CHD,and 58%of the avertable morbidity and mortality due to congenital anomalies would result from scaling congenital heart surgery services[2].Every year,nearly 300,000 children and adults die from CHD,the majority of whom live in low-and middle-income countries(LMICs)[3].Approximately 49%of all individuals with CHD will require surgical or interventional care at some point in their lifetime[4];as a result of advances in access to and the delivery of such services,over 95%of children born with CHD in high-income countries now live into adulthood[3].Here,adults have surpassed children in the number of CHD cases at a ratio of 2:1[5].

Sodium-Glucose Cotransporter 2 Inhibitors in Adult and Pediatric Congenital Heart Disease: Review of Emerging Data and Future Directions

Heart failure(HF)is common in patients with congenital heart disease(CHD)and there are limited medical therapies.Sodium-glucose cotransporter 2 inhibitors(SGLT2i)are a proven medical therapy in patients with acquired HF,though data are limited in patients with CHD.The aim of this review is to summarize the current evidence for use of SGLT2i in patients with CHD and identify future directions for study.In available publica-tions,SGLT2i in patients with CHD seem to be well tolerated,with similar side effect profile to patients with acquired HF.Improvement in functional capacity and natriuretic peptides are mixed,though there is a signal for potential reduction in HF hospitalizations.One prospective study in patients with systemic right ventricles showed an improvement in systolic function for patients already on maximal HF medical therapy.Though lim-ited,there is emerging data on use of SGLT2i in pediatric patients with CHD and HF.Future prospective studies are needed to evaluate for clinically meaningful endpoints,including HF hospitalization,as well as evaluate the hemodynamic impact in subtypes of CHD at high risk for HF.

Machine Learning-Based Intelligent Auscultation Techniques in Congenital Heart Disease:Application and Development

Congenital heart disease(CHD),the most prevalent congenital ailment,has seen advancements in the“dual indi-cator”screening program.This facilitates the early-stage diagnosis and treatment of children with CHD,subse-quently enhancing their survival rates.While cardiac auscultation offers an objective reflection of cardiac abnormalities and function,its evaluation is significantly influenced by personal experience and external factors,rendering it susceptible to misdiagnosis and omission.In recent years,continuous progress in artificial intelli-gence(AI)has enabled the digital acquisition,storage,and analysis of heart sound signals,paving the way for intelligent CHD auscultation-assisted diagnostic technology.Although there has been a surge in studies based on machine learning(ML)within CHD auscultation and diagnostic technology,most remain in the algorithmic research phase,relying on the implementation of specific datasets that still await verification in the clinical envir-onment.This paper provides an overview of the current stage of AI-assisted cardiac sounds(CS)auscultation technology,outlining the applications and limitations of AI auscultation technology in the CHD domain.The aim is to foster further development and refinement of AI auscultation technology for enhanced applications in CHD.

Congenital heart“Challenges”in Down syndrome

In this editorial,we comment on the article by Kong et al published in the recent issue of the World Journal of Cardiology.In this interesting case,the authors present the challenges faced in managing a 13-year-old patient with Down syndrome(DS)and congenital heart disease(CHD)associated with pulmonary arterial hypertension.In this distinct population,the Authors underscore the need for early diagnosis and management as well as the need of a multidisciplinary approach for decision making.It seems that the occurrence of CHD in patients with DS adds layers of complexity to their clinical management.This editorial aims to provide a comprehensive overview of the intricate interplay between DS and congenital heart disorders,offering insights into the nuanced diagnostic and therapeutic considerations for physicians.

Sodium glucose cotransporter 2 inhibitors in the management of heart failure:Veni,Vidi,and Vici

Heart failure(HF)is a chronic disease associated with high morbidity and mortality rates.Renin-angiotensin-aldosterone system blockers(including angiotensin receptor/neprilysin inhibitors),beta-blockers,and mineralocorticoid receptor blockers remain the mainstay of pharmacotherapy for HF with reduced ejection fraction(HFrEF).However,despite the use of guideline-directed medical therapy,the mortality from HFrEF remains high.HF with preserved ejection fraction(HFpEF)comprises approximately half of the total incident HF cases;however,unlike HFrEF,there are no proven therapies for this condition.Sodium glucose cotransporter-2 inhibitors(SGLT-2is)represent a new class of pharmacological agents approved for diabetes mellitus(DM)that inhibit SGLT-2 receptors in the kidney.A serendipitous finding from seminal trials of SGLT-2is in DM was the significant improvement in renal and cardiovascular(CV)outcomes.More importantly,the improvement in HF hospitalization(HHF)in the CV outcomes trials of SGLT-2is was striking.Multiple mechanisms have been proposed for the pleiotropic effects of SGLT-2is beyond their glycemic control.However,as patients with HF were not included in any of these trials,it can be considered as a primary intervention.Subsequently,two landmark studies of SGLT-2is in patients with HFrEF,namely,an empagliflozin outcome trial in patients with chronic HF and a reduced ejection fraction(EMPEROR-Reduced)and dapagliflozin and prevention of adverse outcomes in HF(DAPA-HF),demonstrated significant improvement in HHF and CV mortality regardless of the presence of DM.These impressive results pitchforked these drugs as class I indications in patients with HFrEF across major guidelines.Thereafter,empagliflozin outcome trial in patients with chronic HF with preserved ejection fraction(EMPEROR-Preserved)and dapagliflozin evaluation to improve the lives of patients with preserved ejection fraction HF(DELIVER)trials successively confirmed that SGLT-2is also benefit patients with HFpEF with or without DM.These results represent a watershed as they constitute the first clinically meaningful therapy for HFpEF in the past three decades of evolution of HF management.Emerging positive data for the use of SGLT-2is in acute HF and post-myocardial infarction scenarios have strengthened the pivotal role of these agents in the realm of HF.In a short span of time,these classes of drugs have captivated the entire scenario of HF.

Kill two birds with one stone:Hapatologist’s approach to metabolic dysfunction-associated steatotic liver disease and heart failure

Heart failure(HF)is a major global public health concern,and one of the less commonly known risk factors for HF development is metabolic dysfunction-associated steatotic liver disease(MASLD),as they share a similar pathophysio-logical background.In this article,we evaluated a recently published review article by Arriola-Montenegro et al.This article briefly summarizes the common pathophysiology of HF and MASLD development and evaluates the available therapeutic options to treat both conditions.Clinical practice guidelines highlight the importance of initiating and titrating guideline-directed medication therapy(GDMT)for patients with HF with reduced ejection fraction.GDMT is comprised of the four pillars currently proposed in most clinical practice guidelines,namely angiotensin-converting enzyme inhibitors(ACEIs),angiotensin receptor blockers(ARBs),angiotensin receptor-neprilysin inhibitors,beta-blockers,mineralocor-ticoid receptor antagonists,and sodium-glucose co-transporter 2 inhibitors(SGLT-2i).Given the similarity of pathophysiology and risk factors,recent studies for GDMT regarding ACEIs,ARBs,mineralocorticoid receptor antagonists,and SGLT-2i have shown beneficial effects on MASLD.Nonetheless,other medications for both conditions and novel therapies require more robust data and well-designed clinical studies to demonstrate their efficacies in both conditions.

Electroacupuncture improves myocardial fibrosis in heart failure rats by attenuating ECM collagen deposition through modulation of TGF-β1/Smads signaling pathway

Background: To explore the effects of electroacupuncture on cardiac function and myocardial fibrosis in rat models of heart failure, and to elucidate the underlying mechanism of electroacupuncture in heart failure treatment. Methods: Healthy male Sprague-Dawley rats were allocated into three groups: Sham group, Model group, and electroacupuncture (Model + EA) group, with each group comprising 8 rats. The model underwent a procedure involving the ligation of the left anterior descending coronary artery to induce a model of heart failure. The Model + EA group was used for 7 consecutive days for electroacupuncture of bilateral Shenmen (HT7) and Tongli (HT5), once a day for 30 min each time. Left ventricular parameters in rats were assessed using a small-animal ultrasound machine to analyze changes in left ventricular end-diastolic volume, left ventricular end-systolic volume, left ventricular ejection fraction, and left ventricular fractional shortening. Serum interleukin-1β (IL-1β), cardiac troponin (cTn), and N-terminal brain natriuretic peptide precursor levels were measured using ELISA. Histopathological changes in rat myocardium were observed through HE staining, while collagen deposition in rat myocardial tissue was assessed using the Masson staining method. Picro sirius red staining, immunohistochemical staining, and RT-qPCR were utilized to distinguish between the various types of collagen deposition. The expression level of TGF-β1 and SMAD2/3/4/7 mRNA in rat myocardial tissues was determined using RT-qPCR. Additionally, western blot analysis was conducted to assess the protein expression levels of TGF-β1, SMAD3/7, and p-SMAD3 in rat myocardial tissues. Results: Compared with the Sham group, the left ventricular ejection fraction and left ventricular fractional shortening values of the Model group were significantly decreased (P < 0.01);the left ventricular end-diastolic volume and left ventricular end-systolic volume values were remarkably increased (P < 0.01);serum N-terminal brain natriuretic peptide precursor content was increased (P < 0.01);serum IL-1β and cTn levels were increased (P < 0.01);myocardial collagen volume fraction were increased (P < 0.01);and those of the expression of TGF-β1 and SMAD2/3/4 mRNA was increased (P < 0.01);the expression of SMAD7 mRNA was decreased (P < 0.01);the protein expression levels of TGF-β1, SMAD3, and p-Smad3 were increased (P < 0.01);the protein expression level of SMAD7 was decreased (P < 0.01) in the Model group. Compared to the Model group, the expression levels of the proteins TGF-β1, SMAD3, and p-Smad3 in myocardial tissue were found to be decreased (P < 0.01), and the expression level of the protein SMAD7 was found to be increased (P < 0.01) in the Model + EA group;the collagen volume fraction and deposition of type Ⅰ /Ⅲ collagen were decreased (P < 0.01) in the Model + EA group. Conclusion: Electroacupuncture alleviates myocardial fibrosis in rats with heart failure, and this effect is likely due to attributed to the modulation of the TGF-β1/Smads signaling pathway, which helps reduce collagen deposition in the extracellular matrix.

Living biodrugs and how tissue source influences mesenchymal stem cell therapeutics for heart failure

In this editorial we comment on the article by Safwan M et al.We especially fo-cused on the cardiac function restoration by the use of mesenchymal stem cells(MSCs)therapy for heart failure(HF),which has emerged as a new treatment approach as“Living Biodrugs”.HF remains a significant clinical challenge due to the heart’s inability to pump blood effectively,despite advancements in medical and device-based therapies.MSCs have emerged as a promising therapeutic approach,offering benefits beyond traditional treatments through their ability to modulate inflammation,reduce fibrosis,and promote endogenous tissue rege-neration.MSCs can be derived from various tissues,including bone marrow and umbilical cord.Umbilical cord-derived MSCs exhibit superior expansion ca-pabilities,making them an attractive option for HF therapy.Conversely,bone marrow-derived MSCs have been extensively studied for their potential to im-prove cardiac function but face challenges related to cell retention and delivery.Future research is focusing on optimizing MSC sources,enhancing differentiation and immune modulation,and improving delivery methods to overcome current limitations.

Dapagliflozin in heart failure and type 2 diabetes:Efficacy,cardiac and renal effects,safety

BACKGROUND Heart failure(HF),especially HF with reduced ejection fraction(HFrEF),presents complex challenges,particularly in the aging population where it often coexists with type 2 diabetes mellitus(T2DM).AIM To analyze the effect of dapagliflozin treatment on cardiac,renal function,and safety in patients with HFrEF combined with T2DM.METHODS Patients with T2DM complicated with HFrEF who underwent treatment in our hospital from February 2018 to March 2023 were retrospectively analyzed as the subjects of this study.The propensity score matching method was used,and a total of 102 eligible samples were scaled.The clinical efficacy of the two groups was evaluated at the end of the treatment,comparing the results of blood glucose,insulin,cardiac function,markers of myocardial injury,renal function indexes,and 6-min walk test(6MWT)before and after the treatment.We compared the occurrence of adverse effects on the treatment process of the two groups of patients.The incidence of adverse outcomes in patients within six months of treatment was counted.RESULTS The overall clinical efficacy rate of patients in the study group was significantly higher than that of patients in the control group(P=0.013).After treatment,the pancreatic beta-cell function index,left ventricular ejection fraction,and glomerular filtration rate of patients in the study group were significantly higher than control group(P<0.001),while their fasting plasma glucose,2-h postprandial glucose,glycosylated hemoglobin,insulin resistance index,left ventricular end-systolic diameter,left ventricular end-diastolic diameter,cardiac troponin I,creatine kinase-MB,N-terminal pro b-type natriuretic peptide,serum creatinine,and blood urea nitrogen were significantly lower than those of the control group.After treatment,patients in the study group had a significantly higher 6MWT than those in the control group(P<0.001).Hypoglycemic reaction(P=0.647),urinary tract infection(P=0.558),gastrointestinal adverse effect(P=0.307),respiratory disturbance(P=0.558),and angioedema(P=0.647)were not statistically different.There was no significant difference between the incidence of adverse outcomes between the two groups(P=0.250).CONCLUSION Dapagliflozin significantly enhances clinical efficacy,cardiac and renal function,and ambulatory capacity in patients with HFrEF and T2DM without an increased risk of adverse effects or outcomes.

Heart abnormality associates with a wide spectrum of psychiatric disorders:Evidence from Mendelian randomization analyses

Psychiatric disorders and heart abnormality are closely interconnected.Previous knowledge has been well-established that psychiatric disorders can lead to increased cardiovascular morbidity and even sudden cardiac death.Conversely,whether heart abnormality contributes to psychiatric disorders remains rarely studied.The work by Zhang et al pointed out that chronic heart failure had effects on the anxiety and depression(AD)severity,and indices including left ventricular ejection fraction,N-terminal pro-brain natriuretic peptide and interleukin-6 were independent risk factors for AD severity.In addition to the aforementioned AD,we herein find that heart failure might additionally impact the development of autism spectrum disorder and post-traumatic stress disorder(albeit P>0.05),and significantly protects against the presence of attention deficit hyperactivity disorder(ADHD),[odds ratio(OR)=0.61,P=0.0071]by using a Mendelian randomization analysis.Bradycardia is also a protective factor for ADHD(OR=0.61,P=0.0095),whereas hypertrophic cardiomyopathy is a mild risk factor for schizophrenia(OR=1.02,P=0.032).These data suggest a wide spectrum of psychiatric disorders secondary to heart abnormality,and we highlight more psychiatric care that should be paid to patients with heart abnormality.

Quran memorisation and heart rate variability:How do they correlate?

BACKGROUND Heart rate variability(HRV)was shown to be affected by performing religious activities.AIM To examine the relationship between the level of Quran(the holy book of Muslims)memorisation and HRV among teenagers.METHODS This experimental study included 16 Tahfiz students and 16 non-Tahfiz students(n=32).The HRV was measured in three tasks:Recalling familiar verses,memorising new verses,and recalling the newly memorised verses of the Quran.HRV analysis was done using these parameters:Standard deviation of N-N(heartbeat peak)interval;low frequency(LF);high frequency(HF)and LF/HF ratio.RESULTS There were significant differences between tasks for all parameters(P<0.05).However,between the groups,only the LF/HF ratio had significant differences,with F=5.04,P<0.05.Pearson correlation showed a moderate positive correlation between the number of pages memorised and the LF/HF ratio(r=0.61,P<0.05).CONCLUSION Quran memorisation increased the HRV and our results suggested that this activity could be developed as an effective sympathovagal modulation training activity.

The Problem of Rehospitalisation for Heart Failure at the Cardiology Department of the Hôpital National Ignace Deen

Introduction: Despite current therapeutic advances, heart failure in sub-Saharan Africa remains a common, serious and costly disease, particularly due to rehospitalizations. The objective of this work was to determine the proportion of rehospitalizations for heart failure and to identify etiological factors. Methodology: This was a retrospective descriptive study with a duration of 8 months from April 1 to November 30, 2021. This study included all patients rehospitalized in the department for Heart Failure and who agreed to participate in our study. Results: During the period of our study, 437 patients were hospitalized in the HF department, among which we collected 126 cases of rehospitalization for HF with a frequency of 28.83%. The mean age of our patients was 46.32 ± 18.98 years with the extremes of 15 to 84 years. The most affected age group was between 35 and 44 years old in 24 cases, i.e. a frequency of 19%. We observed a female predominance of 64 cases, i.e. a frequency of 50.8% compared to 62 cases, i.e. a frequency of 49.2% with a sex ratio (M/F) equal to 0.96. 98 cases of our patients, i.e. a frequency of 77.8%, were mutual insurance companies who felt they had the necessary support from those around them. In our sample, the underlying heart disease was mainly represented by valvular heart disease in 59 cases, followed by hypertensive heart disease in 42 cases with the respective frequencies of 46.82% and 33.33%. The majority of our patients were rehospitalized (1 - 3) times after a first episode of HF flare-up in 117 cases or 92.9%. Irregularity at control and therapeutic break were the most common decompensation factors with frequencies of 75.8% and 74.2% respectively. The majority of our patients were rehospitalized (1 - 3) times after a first episode of HF flare-up in 117 cases or 92.9%. Irregularity at control and therapeutic break were the most common decompensation factors with frequencies of 75.8% and 74.2% respectively. Conclusion: It appears in this study that rehospitalizations for heart failure are frequent, linked to irregularity in control and the lack of therapeutic education.
