Clinical relevance of midkine as a biomarker predicting atherosclerotic risk factors in individuals with type-2 diabetes mellitus: a cross-sectional study

Objective

Midkine (MK) is a member of a small protein family that includes pleiotrophin. MK levels are elevated in obese patients and have a pro-arthrogenic effect through various pathophysiological processes including vascular inflammation and atherogenesis. This study aimed to investigate the association between serum MK levels and several atherosclerotic risk factors in patients with type 2 diabetes mellitus (T2DM).

Methodology

Ninety subjects were enrolled in this study, comprising 60 T2DM patients and 30 age-matched healthy subjects (HS). The patients were categorized into two groups based on dyslipidemia: group 1 consisted of 30 patients with dyslipidemia, while group 2 included 30 patients without dyslipidemia. Laboratory tests were conducted using routine assays at the National Diabetes Center. MK levels were analyzed using enzyme-linked immunosorbent assay (ELISA).

Results

MK levels were significantly higher in patients with dyslipidemia compared to those without dyslipidemia and HS (P ≤ 0.0001). A significant negative correlation was observed between MK levels and the atherogenic index of plasma (AIP), Castelli's risk index-1 (CRI-I), and Castelli's risk index-2 (CRI-II) (r = - 0.489, p = 0.005; r = - 0.465, p = 0.008; r = - 0.421, p = 0.018, respectively) in patients with dyslipidemia. Furthermore, a significant positive correlation was found between MK levels and HDL-C (r = 0.524, p = 0.002) in patients without dyslipidemia. MK, AIP, and CRI-I were identified as predictors of atherosclerosis in DM patients, with MK indicating very good discriminate power (AUC = 0.805) in identifying T2DM patients with dyslipidemia at a cut-off value of ≤ 4.457 ng/ml.

Conclusion

These findings suggest that MK could be considered a predictive biomarker for dyslipidemia associated with DM. MK levels correlate significantly with atherogenic risk factors, indicating its potential as a sensitive risk predictor for atherosclerosis in patients with T2DM.

The Effect of Virtual Reality Therapy on Functional Recovery in Subacute Stroke Patients: A Randomized Controlled Trial

Virtual reality (VR) therapy can potentially enhance upper extremity recovery and motivation in stroke rehabilitation. The BTS Nirvana system, equipped with infrared sensors and real-time audiovisual feedback, enables objective performance recording and supports task-oriented, intensive exercises. This study evaluates the combined effect of VR therapy using BTS Nirvana and conventional rehabilitation on upper extremity functions in subacute stroke patients. This randomized, controlled, single-masked study included 22 subacute hemiplegic patients divided into a virtual reality group (n = 11) and a control group (n = 11). Both groups received conventional therapy for three weeks, with the VR group undergoing additional sessions using the BTS Nirvana system. Upper extremity functions were assessed using the Fugl-Meyer upper extremity scale, Brunnstrom stage, Functional Reach Test, Chedoke Arm and Hand Activity tests, and range of motion measurements. Both groups showed significant improvements (p < 0.05) in most outcomes, except for shoulder adduction (p = 0.222) and shoulder external rotation (p = 0.113). Intergroup analysis favored the VR group for upper extremity Brunnstrom stage (p = 0.030), shoulder external rotation (p = 0.029), and Chedoke arm test scores (p = 0.039). Time-group interaction analysis also highlighted superior improvements in the VR group for these measures (p < 0.05). The BTS Nirvana system is a safe and effective complement to conventional therapy, offering intensive and repetitive training for upper extremity rehabilitation in subacute stroke patients. Further research with larger sample sizes and extended treatment durations is needed to confirm these findings and refine treatment protocols.

Proteomic and Demographic Comparisons of Recurrent Ischemic Stroke Patients

Rates of recurrent strokes have remained relatively unchanged over the past couple decades, highlighting a need for advancements in secondary prevention of stroke recurrence. This study utilizes the Blood And Clot Thrombectomy Registry And Collaboration (BACTRAC) tissue bank to identify proteomic and demographic differences in recurrent ischemic stroke patients. Blood samples were collected during mechanical thrombectomy of large-vessel occlusion ischemic strokes. Plasma levels for 184 inflammatory and cardiometabolic proteins were measured in systemic blood and intracranial blood from the infarction area. Differences between recurrent and first-stroke patients were analyzed using Fisher's Exact Test for categorical variables and Student's independent samples t tests or Welch's t tests for continuous variables. Proteins were divided into systemic and intracranial proteins, and independent samples t tests were performed with a False Discovery Rate of 5.0%. Significant variables were used in multiple logistic regression. There were 20 patients in the prior stroke group and 121 in the first stroke group. The prior stroke group had a significantly higher percentage of females (80.0% vs 50.4%, p = 0.016) and lower rate of hyperlipidemia comorbidity (10.5% vs 35.5%, p = 0.034). Two systemic proteins were significantly higher in those with a prior stroke: CCL14 and FGF-19. Multiple logistic regression found higher levels of CCL14 and FGF-19 to be predictive of a stroke being recurrent. Along with other demographics, these proteins could provide a predictive model to identify patients with risk of recurrent ischemic strokes. Serum CCL14 and FGF-19 levels are easily accessible biomarkers, making them possible therapeutic targets for recurrent stroke prevention.

The Interaction of Hypertension and Obstructive Sleep Apnea Risk on Cognitive Function in Healthy Older Adults

PURPOSE

To preliminarily examine the individual and interaction effects of hypertension and obstructive sleep apnea (OSA) risk on cognitive functions (i.e., global cognition, memory, attention, and executive function).

METHOD

The current study was a secondary data analysis. Forty older adults were retrieved from a descriptive study. OSA risk was measured by the STOP-BANG questionnaire, and hypertension by self-report and medications used. Spearman rho correlation and two-way analysis of covariance were used in the data analysis.

RESULTS

After controlling for covariates (i.e., age, educational years, health conditions, body mass index, and depressive symptoms), older adults with hypertension had poorer memory and attention; older adults with high OSA risk had poorer memory and better executive function. This interaction effect of hypertension and OSA risk on executive function was significant.

CONCLUSION

The association between hypertension and memory and attention and between OSA risk and memory in older adults was supported. The interaction effect was found in executive function but unexpected. Future studies are needed to recruit older adults with hypertension and diagnosed OSA to explore these interaction effects. [Research in Gerontological Nursing, xx(x), xx-xx.].

Veterinary medical care in rodent models of stroke: Pitfalls and refinements to balance quality of science and animal welfare

Rodent models of cerebral ischemia provide a valuable contribution to a better understanding of stroke pathophysiology, to validate diagnostic methods, and to enable testing of new treatments for ischemia-reperfusion damage and comorbidities. However, ethical concerns have led to increased attention to the welfare aspects of such models. Supportive therapies are an essential part of the overall animal care and use program and should be tailored to the experimental model being studied, the regulatory requirements, and research objectives to achieve high-quality preclinical studies and ethical research practices. On the other hand, the use of veterinary medical treatments in preclinical models of stroke must balance the needs of animal care and potential sources of bias in experimental results. This report provides a systematic review of the scientific literature covering the relevant period from years 1988 to September 2024, with the aim to investigating veterinary medical interventions useful to minimize suffering in rodent models of stroke without producing experimental bias. The research findings, consolidated from 181 selected studies, published from 1991 to 2023, indicate the feasibility of implementing personalized protocols of anesthesia, analgesics, antibiotics, and other supportive therapies in rodent models of stroke, while avoiding scientific interferences. These data fill a gap in current knowledge and could be of interest for an interdisciplinary audience working with rodent models of stroke, stimulating further refinements to safeguard both animal welfare and the validity of experimental findings, and may promote the culture of ethical conduct in various research fields and disciplines.

Impact of Inpatient Stroke Rehabilitation on Caregivers' Perceived Readiness for Patient Discharge

PURPOSE

The purpose of this study is to assess the extent to which caregivers' perceived readiness for discharge improves after participating in a stroke inpatient rehabilitation program, as measured by their self-reported preparedness for transitioning patients to the community.

DESIGN

This was a prospective study involving pre- and postsurveys of caregivers.

METHODS

The Preparedness Assessment for the Transition Home After Stroke (PATH-s) survey instrument was administered to caregivers of patients following a stroke at admission and discharge from inpatient rehabilitation. The PATH-s final score is an average that ranges from 1 to 4. A higher average score indicates higher readiness for discharge.

RESULTS

Twenty-five patient-caregiver dyads complete the study protocol representing a 42% survey response rate of consented participants for both the initial and discharge PATH-s surveys. The initial mean PATH-s was 2.86 (SD = 0.434), and the discharge mean PATH-s was 3.25 (SD = 0.436). The differences between these scores were significant (Z = -4.280, p ≤ .0001), suggesting participation with inpatient rehabilitation following a stroke improved the caregivers' self-reported readiness for discharge.

CLINICAL RELEVANCE

It is important for rehabilitation nurses to be aware of the caregiver's self-reported readiness for discharge to address any issues identified to improve transition for discharge following a stroke.

CONCLUSION

Caregiver readiness for discharge is an important issue yet it may be an undervalued aspect of the care delivery system.

Gut microbiota-related modulation of immune mechanisms in post-infarction remodelling and heart failure

The immune system has long been recognized as a key driver in the progression of heart failure (HF). However, clinical trials targeting immune effectors have consistently failed to improve patient outcome across different HF aetiologies. The activation of the immune system in HF is complex, involving a broad network of pro-inflammatory and immune-modulating components, which complicates the identification of specific immune pathways suitable for therapeutic targeting. Increasing attention has been devoted to identifying gut microbial pathways that affect cardiac remodelling and metabolism and, thereby impacting the development of HF. In particular, gut microbiota-derived metabolites, absorbed by the host and transported to the peripheral circulation, can act as signalling molecules, influencing metabolism and immune homeostasis. Recent reports suggest that the gut microbiota plays a crucial role in modulating immune processes involved in HF. Here, we summarize recent advances in understanding the contributory role of gut microbiota in (auto-)immune pathways that critically determine the progression or alleviation of HF. We also thoroughly discuss potential gut microbiota-based intervention strategies to treat or decelerate HF progression.

Effect of physical activity on left ventricular dimensions and function after myocardial infarction: a systematic review

INTRODUCTION

Coronary artery disease is the major pathophysiological driver of ventricular remodeling. A multimodal intervention is the key strategy to promote a positive left ventricular remodeling with improvement in volumes and ejection fraction, known as "reverse remodeling." The aim of this review was to highlight the effect of physical activity (PA) on echocardiographic and cardiac magnetic resonance parameters of left ventricle in patients with myocardial infarction.

EVIDENCE ACQUISITION

We performed a systematic review of the literature to summarize current evidence about the efficacy (in terms of improvement in chamber dimensions, ejection fraction, speckle tracking and diastolic function) of physical activity in patients with myocardial infarction, supported by echocardiographic or magnetic resonance data. Articles were searched in Pubmed, Cochrane Library and Biomed Central.

EVIDENCE SYNTHESIS

Only papers published in English and in peer-reviewed journals up to November 2022 were selected. After an initial evaluation, 1029 records were screened; the literature search identified 20 relevant articles. From this data, some PA protocols appeared to favor left ventricular reverse remodeling.

CONCLUSIONS

PA provides beneficial effects on left ventricular parameters analyzed by echocardiography and cardiac magnetic resonance.

Soluble urokinase plasminogen activator receptor (suPAR) as a prognostic biomarker in acutely admitted patients with atrial fibrillation

Background

Atrial fibrillation (AF) is associated with a higher incidence of stroke, heart failure, and mortality. Risk assessment of clinical outcomes in patients hospitalized acutely with AF remains a challenge.

Purpose

To investigate if soluble urokinase plasminogen activator receptor (suPAR) levels at admission to the Emergency Department (ED) are associated with 1-year all-cause mortality in patients admitted with AF.

Methods

A prospective cohort study of patients consecutively admitted to the medical ED of a university hospital in Copenhagen, Denmark, between 2020 and 2022 with symptoms of COVID-19. Patients were included if they were admitted with AF as the primary or secondary diagnosis. All patients had suPAR measured at the index admission, and follow-up was up to 1 year. The association between suPAR and 1-year mortality was investigated with multivariate Cox regression. We adjusted for age, sex, smoking, C-reactive protein, creatinine, hemoglobin, albumin, and comorbidities.

Results

Of the 7,258 patients included during the period, 362 (5.0%) patients were admitted with AF as the primary or secondary diagnosis. Due to missing data, 23 (6.4%) patients were excluded. Among the remaining 339 patients, 68 (20.1%) patients were dead at follow-up. The multivariate Cox regression showed that elevated suPAR was independently associated with an increased risk of 1-year mortality, with a hazard ratio of 1.12 (95% confidence interval: 1.05-1.20, p < 0.001).

Conclusion

Elevated suPAR levels were significantly associated with 1-year all-cause mortality in patients acutely admitted with AF to the ED.

Recent advances in microneedles for enhanced functional angiogenesis and vascular drug delivery

Many therapeutic applications use the transdermal method to avoid the severe restrictions associated with oral medication delivery. Given the limitations of traditional drug delivery via skin, transdermal microneedle (MN) arrays have been reported to be versatile and very efficient devices due to their outstanding characteristics such as painless penetration, affordability, excellent medicinal efficacy, and relative safety. MNs have recently received increased attention for their ability to cure vascular illnesses such as hypertension and thrombosis, as well as promote wound healing via the angiogenesis impact. The integrant of method manufacturing and biodegradable material allows for the modification of MN form and drug release pattern, hence increasing the flexibility of such drug delivery. In this review, we focused on recent improvements in MN-mediated transdermal administration of protein and peptide medicines for improved functional angiogenesis and vascular therapy. We also provide an overview of the present applications of MNs-mediated transdermal protein and peptide administration, particularly in the realm of vascular system disease therapy. Finally, the current state of clinical translation and a forecast for future progress are provided.

Tissue elasticity modulates cardiac pacemaker cell automaticity

Tissue elasticity is essential to a broad spectrum of cell biology and organ function including the heart. Routine cell culture models on rigid polystyrene dishes are limited in studying the impact of tissue elasticity in distinct regions of the myocardium such as the cardiac conduction system. Gelatin, a derivative of collagen, is a simple and tunable platform for modeling tissue elasticity. We sought to study the effects of increasing tissue stiffness on cardiac pacemaker cell function by using transcription factor-reprogrammed pacemaker cells cultured on gelatin hydrogels with specific elasticity. Our data indicate that automaticity of the pacemaker cells, measured in rhythmic contractions and oscillating intracellular Ca2+ transients, was enhanced when cultured on a stiffer matrix of 14 kPa. This was accompanied by increased expression of cardiac pacemaker ion channel, Hcn4, and a reciprocal decrease in Cx43 expression compared with control conditions. Propagation of Ca2+ transients was slower in the pacemaker cell monolayers compared with control, which recapitulates a hallmark feature in the native pacemaker tissue. Ca2+ transient propagation of pacemaker cell monolayer was slower on stiffer than on softer hydrogel, and this was dependent on enhanced proliferation of cardiac fibroblasts rather than differences in gap junctional coupling. Culturing the pacemaker cells on rigid plastic plates led to irregular or loss of synchronous contractions as well as unusually long Ca2+ transient durations. Taken together, our data demonstrate that automaticity of pacemaker cells is augmented by stiffer extracellular matrix substrates within the elasticity range of the healthy myocardium. This simple approach presents a physiological in vitro model to study mechanoelectric feedback of cardiomyocytes including the conduction system cells.NEW & NOTEWORTHY The major achievement of this work is development of a robust and straightforward approach to model cardiac conduction system cells with a range of cardiac tissue elasticity with a goal to understand the impact of tissue stiffness on cardiac pacing. Our data provide a framework for further investigation of the heart rhythm in health and disease in the context of fibrosis.

Association of hemoglobin-to-red blood cell distribution width ratio with mortality in critically Ill patients with heart failure and acute kidney injury: insights from the MIMIC-IV database

BACKGROUND

The association between the hemoglobin-to-red cell distribution width ratio (HRR) and mortality in critically ill patients with heart failure (HF) and acute kidney injury (AKI) remains uncertain. This research focuses on exploring the association between HRR and both short-term and long-term all-cause mortality in these patients.

METHODS

Participants were selected from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database and categorized into tertiles based on HRR values. The primary endpoint was 28-days ICU all-cause mortality. Secondary endpoints included 28-days hospital and 90-days hospital all-cause mortality. Cox proportional hazards models and restricted cubic splines were used to analyze the association between HRR and mortality in patients with HF and AKI. Kaplan-Meier survival analysis estimated endpoint differences across tertiles.

RESULTS

A total of 7561 patients were included, with 55.5% being male (n=4199). Cox proportional hazards analysis showed a significant link between HRR and both short-term and long-term mortality in critically ill patients with HF and AKI. This association remained significant after adjusting for confounders. The restricted cubic splines model demonstrated a linear relationship between a higher HRR index and a reduced mortality risk. Kaplan-Meier survival analysis revealed significant differences in short-term and long-term mortality among the tertile groups.

CONCLUSION

The study results show a strong association between lower HRR and increased short-term and long-term mortality in critically ill patients with heart failure and AKI. HRR proves to be a valuable and cost-effective marker for identifying high-risk patients.

Continuous quality improvement for prehospital STEMI improved triage rates and achievement of gold standard < 90-min EMS-to-balloon time

BACKGROUND

ST-elevation myocardial infarction (STEMI) is a type of myocardial infarction caused by a buildup of plaque or clot in the coronary arteries. There are approximately 750,000 STEMI cases each year in the United States. The American Heart Association's Mission Lifeline initiative aimed to optimize prehospital emergency medical services (EMS) and enhance STEMI triage rates through improved standardized protocol. This study evaluates the implementation of Mission Lifeline techniques by Polk County Fire Rescue (PCFR) on improved EMS-to-balloon (E2B) times and triage rates.

METHODS

Data from PCFR, Florida's 4th largest EMS system, were analyzed quarterly from 2015 to 2023. The study included patients with chest pain that were > 35 years of age.

RESULTS

Among 2,585 patients, the percentage meeting the 90-min EMS-to-Balloon time increased from 74% in 2015 to 84% by the year 2019. The average annual under-triage rate for STEMI decreased from ranging from 2% in 2015 to 4% in 2017 to below 1% after the year 2020, reaching as low as 0% in 2021 and 2023. Over-triage rates initially fluctuated, increasing to a height of 12% by 2017, but decreased to < 3% by 2022 and further dropped to 0.6% of cases were over-triage by 2024.

CONCLUSION

Implementation of Mission Lifeline procedures, including obtaining pre-hospital 12-lead ECG and hospital pre-activation, significantly enhanced STEMI care. These interventions led to improved E2B times and more accurate prehospital STEMI identification, underscoring the importance of coordinated, protocol-driven prehospital STEMI care in improving patient outcomes.

An Actor-Partner Interdependence Mediation Model for Assessing the Association Between Health Literacy and mHealth Use Intention in Dyads of Patients With Chronic Heart Failure and Their Caregivers: Cross-Sectional Study

Background

Chronic heart failure (CHF) has become a serious threat to the health of the global population. Self-management is the key to treating CHF, and the emergence of mobile health (mHealth) has provided new ideas for the self-management of CHF. Despite the many potential benefits of mHealth, public utilization of mHealth apps is low, and poor health literacy (HL) is a key barrier to mHealth use. However, the mechanism of the influence is unclear.

Objective

The aim of this study is to explore the dyadic associations between HL and mHealth usage intentions in dyads of patients with CHF and their caregivers, and the mediating role of mHealth perceived usefulness and perceived ease of use in these associations.

Methods

This study had a cross-sectional research design, with a sample of 312 dyads of patients with CHF who had been hospitalized in the cardiology departments of 2 tertiary care hospitals in China from March to October 2023 and their caregivers. A general information questionnaire, the Chinese version of the Heart Failure-Specific Health Literacy Scale, and the mHealth Intention to Use Scale were used to conduct the survey; the data were analyzed using the actor-partner interdependence mediation model.

Results

The results of the actor-partner interdependent mediation analysis of HL, perceived usefulness of mHealth, and mHealth use intention among patients with CHF and their caregivers showed that all of the model's actor effects were valid (β=.26-0.45; P<.001), the partner effects were partially valid (β=.08-0.20; P<.05), and the mediation effects were valid (β=.002-0.242, 95% CI 0.003-0.321; P<.05). Actor-partner interdependent mediation analyses of HL, perceived ease of use of mHealth, and mHealth use intention among patients with CHF and caregivers showed that the model's actor effect partially held (β=.17-0.71; P<.01), the partner effect partially held (β=.15; P<.01), and the mediation effect partially held (β=.355-0.584, 95% CI 0.234-0.764; P<.001).

Conclusions

Our study proposes that the HL of patients with CHF and their caregivers positively contributes to their own intention to use mHealth, suggesting that the use of mHealth by patients with CHF can be promoted by improving the HL of patients and caregivers. Our findings also suggest that the perceived usefulness of patients with CHF and caregivers affects patients' mHealth use intention, and therefore patients with CHF and their caregivers should be involved throughout the mHealth development process to improve the usability of mHealth for both patients and caregivers. This study emphasizes the key role of patients' perception that mHealth is easy to use in facilitating their use of mHealth. Therefore, it is recommended that the development of mHealth should focus on simplifying operational procedures and providing relevant operational training according to the needs of the patients when necessary.

Trends in hypertensive heart disease-related mortality among older adults in the USA: a retrospective analysis from CDC WONDER between 1999 and 2020

BACKGROUND

While hypertensive heart disease (HHD) has been widely studied, this study uniquely examines the impact of the COVID-19 pandemic on HHD mortality trends, which has not been thoroughly explored in the current literature. The pandemic's effects on healthcare access, economic instability, and social isolation present new challenges and opportunities for understanding HHD mortality among the elderly.

RESULTS

Age-adjusted mortality rates (AAMRs) increased overall between 1999 and 2020, from 36.7 to 133.9 per 100,000 people, according to analysis. The data on AAMRs indicated a consistent rise from 1999 to 2017, with a notable uptick from 2017 to 2020. An investigation based on gender revealed that older men had a consistently higher AAMR than older women. The biggest AAMRs were found among the non-Hispanic (NH) Black or African-American population, according to variations in AAMR based on race and ethnicity. Geographic differences between states revealed that compared to Nebraska, Oregon, North Dakota, Maine, and Minnesota, the District of Columbia, Oklahoma, Nevada, Vermont, and Mississippi had substantially higher AAMRs. The West, Northeast, and Midwest were in second place with a continuously higher AAMR, followed by the South. Furthermore, compared to non-metropolitan areas, metropolitan areas had a higher AAMR.

CONCLUSION

The importance of including demographic and geographic factors in public health planning and interventions is highlighted by these findings, which provide insightful information on mortality trends associated with HHD in the elderly.

Behavioral delays in seeking care among post-acute myocardial infarction women: a qualitative study following percutaneous coronary intervention

Background

Cardiovascular diseases (CVD) remain the leading cause of mortality worldwide, with ischemic heart disease contributing significantly to female morbidity and mortality. Despite this, women often delay seeking medical help during acute myocardial infarction (AMI), leading to poorer outcomes compared to men.

Objective

To describe the early experiences of Italian women with AMI, focusing on behaviors that delay access to care.

Methods

Using a phenomenological approach, in-depth interviews were conducted with 22 women hospitalized in Campania, Italy, within five days of an AMI event and their Percutaneous Coronary Intervention (PCI), to capture vivid recollections of the experience. Thematic analysis was employed to identify key themes regarding risk behaviors and delays in care.

Results

Five key themes emerged: (1) vivid recollection of symptoms and experience, (2) lack of knowledge and risk perception of AMI, (3) decision-making process in seeking assistance, (4) influence of family and others on decision-making, and (5) post-AMI reflections on seeking medical care. Delays in seeking care stemmed from symptom misrecognition, social responsibilities, past healthcare experiences, and the role of family in decision-making, which either facilitated or hindered access to care.

Conclusion

The findings highlight the need for targeted educational interventions that address barriers specific to women in recognizing and responding to AMI symptoms. Gender-specific training for healthcare professionals is essential to ensure timely and appropriate care for women.

Gender specific echocardiographic prevalence of valvular stenosis and regurgitations in a large inpatient database of 24,265 patients

INTRODUCTION

Prevalence of different valvular pathologies has not been reported in female and male patients in large population-based studies. The goal of this study was to report the gender-specific prevalence of various valvular pathologies.

METHODS

We retrospectively analyzed 24,265 echocardiograms performed between 1984 and 1998. The prevalence of mitral regurgitation (MR) aortic valve regurgitation (AR) and stenosis (AS), and tricuspid regurgitation (TR) were calculated in female and male patients.

RESULTS

Echocardiograms were performed on 12,926 (53%) female and 11,339 (47%) male patients. Gender-specific echocardiographic prevalence of different valvular abnormalities was as follows: Prevalence of mitral regurgitations was similar in women and men (25% vs 24.7%). Aortic regurgitation was higher in males (5.5 vs 14.9%, P < 0.001). Aortic stenosis prevalence was similar between both genders (2.1 vs 2.3%). Tricuspid valve regurgitations were slightly higher in females (18.5 vs 16.7%, P < 0.001).

CONCLUSION

In this study, we found a significantly higher prevalence of tricuspid valve regurgitation in women. Aortic regurgitation was more prevalent in men. Aortic stenosis and mitral regurgitation had similar prevalence in both genders.

Identification of Potential Diagnostic Biomarkers of Carotid Atherosclerosis in Obese Populations

Objective

This study aimed to investigate the potential mechanisms and biomarkers between Obesity (OB) and carotid atherosclerosis (CAS).

Methods

The GSE12828, GSE125771, GSE43292, and GSE100927 datasets were combined and normalized to obtain CAS-related differentially expressed genes (DEGs), and OB-related DEGs were obtained from the GSE151839 dataset and the GeneCards database. Unsupervised cluster analysis was conducted on CAS samples based on the DEGs of CAS and OB. Subsequently, immune infiltration analysis and gene set enrichment analysis (GESA) were performed. 61 machine learning models were developed to screen for Hub genes. The Single-gene GESA focused on calcium signaling pathway-related genes (CaRGs). Finally, high-fat diet-fed C57BL/6J ApoE-/- mice were used for in vivo validation.

Results

MMP9, PLA2G7, and SPP1 as regulators of the immune infiltration microenvironment in OB patients with CAS, and stratified CAS samples into subtypes with differences in metabolic pathways based on OB classification. Enrichment analysis indicated abnormalities in immune and inflammatory responses, the calcium signaling, and lipid response in obese CAS patients. The RF+GBM model identified CD52, CLEC5A, MMP9, and SPP1 as Hub genes. 15 CaRGs were up-regulated, and 12 were down-regulated in CAS and OB. PLCB2, PRKCB, and PLCG2 were identified as key genes in the calcium signaling pathway associated with immune cell infiltration. In vivo experiments showed that MMP9, PLA2G7, CD52, SPP1, FYB, and PLCB2 mRNA levels were up-regulated in adipose, aortic tissues and serum of OB and AS model mice, CLEC5A was up-regulated in aorta and serum, and PRKCB was up-regulated in adipose and serum.

Conclusion

MMP9, PLA2G7, CD52, CLEC5A, SPP1, and FYB may serve as potential diagnostic biomarkers for CAS in obese populations. PLCB2 and PRKCB are key genes in the calcium signaling pathway in OB and CAS. These findings offer new insights into clinical management and therapeutic strategies for CAS in obese individuals.

Cardiac Contractility Modulation Therapy and Device Algorithm-related Challenges

Heart failure (HF) is a complex and potentially life-threatening medical condition posing significant risks to individuals. It is associated with substantial health care expenditures, considerable morbidity and mortality, and a decline in functional capacity and quality of life. Cardiac contractility modulation (CCM) has emerged as a promising device-based treatment for patients with HF with reduced ejection fraction (HFrEF). Studies have shown that CCM treatment in HFrEF patients can improve exercise tolerance and quality of life and reduce HF hospitalizations. As CCM therapy becomes a more prevalent treatment for HFrEF, the natural learning curve inherent in the use of new technologies necessitates broader provider training and careful patient follow-up. To that end, this article highlights the importance of developing a fundamental troubleshooting algorithm to help optimize the management of patients who have an implanted CCM device.

Metabolic Syndrome in the Amazon: Customizing Diagnostic Methods for Urban Communities

Background/Objectives: Metabolic syndrome is a significant public health issue, particularly in urbanizing regions like the Peruvian Amazon, where lifestyle changes have increased the prevalence of metabolic disorders. This study aimed to develop and validate a simple, cost-effective diagnostic model for early detection of metabolic syndrome in the urban population of San Juan Bautista, Iquitos. Methods: A cross-sectional study was conducted with 251 adults aged over 18 years. Data collection included anthropometric measurements, body composition analysis, and biochemical assessments. Logistic regression analyses identified key predictors of metabolic syndrome, and clinical decision trees were developed to enhance diagnostic accuracy. Results: The prevalence of metabolic syndrome was 47.9%. Systolic blood pressure, triglycerides, and very-low-density lipoprotein cholesterol were the strongest predictors. The most effective diagnostic model, combining very-low-density lipoprotein cholesterol and systolic blood pressure, achieved a sensitivity of 91.6% and a specificity of 78.5%, demonstrating high diagnostic accuracy. Conclusions: The proposed model offers a practical, low-cost tool for early detection of metabolic syndrome in resource-limited urban settings. However, its findings are limited by the small sample size and the lack of external validation, requiring further studies to confirm its generalizability and applicability to other populations. Its implementation in primary healthcare could facilitate timely interventions, reducing the risk of chronic diseases in vulnerable populations.

Adjunctive Mantram Repetition Program to Promote Lifestyle Modifications for Managing Impaired Glucose Tolerance: A Case Report from the USA

We report the case of a 63-year-old man with impaired fasting glucose who was unable to lose weight, engage in exercise or omit refined carbohydrates from his diet until he initiated the Mantram Repetition Program (MRP). Four months following implementation, the patient had lost weight and fasting glucose levels decreased to near normal. These parameters continued to improve at nine months. The patient attributed his success to the adjunctive mantram repetition program which also improved his mood and wellbeing. Implementation of the MRP may be a useful adjunct to promote lifestyle changes in patients with mental health diagnoses.

Dexmedetomidine Inhibits Ferroptosis to Alleviate Hypoxia/Reoxygenation-Induced Cardiomyocyte Injury by Regulating the HDAC2/FPN Pathway

PURPOSE

Myocardial ischemia/reperfusion injury (MIRI) is closely associated with ferroptosis. Dexmedetomidine (Dex) has good therapeutic effects on MIRI. This study investigates whether dexmedetomidine (Dex) regulates ferroptosis during MIRI by affecting ferroportin1 (FPN) levels and elucidates the underlying mechanisms.

METHODS

A murine MIRI model was established using male C57BL/6 J mice subjected to 30 min of left anterior descending coronary artery ligation followed by 48 h of reperfusion. In vitro, cardiomyocyte hypoxia/reoxygenation (H/R) models were created with 16 h of hypoxia and 8 h of reoxygenation. Triphenyltetrazolium chloride (TTC) staining was employed to determine infarct size. The pathological changes in myocardial tissues were assessed using hematoxylin-eosin (HE) staining. Lipid reactive oxygen species (ROS) level was detected using BODIPY™ 581/591 C11, and ferrous iron (Fe2+) and malondialdehyde (MDA) levels were measured using the kits. Cardiomyocyte viability was examined using cell counting kit-8 (CCK8) assay. The histone H3 lysine 27 acetylation (H3K27Ac) level in the FPN promoter region was determined using DNA pulldown assay. Chromatin immunoprecipitation (ChIP) assay was used to investigate the relationship between histone deacetylase 2 (HDAC2) and FPN promoter.

RESULTS

Dex alleviated ferroptosis in cardiomyocytes by upregulating FPN levels, which mitigated H/R-induced oxidative damage. FPN knockdown abolished the protective effects of Dex, confirming its dependence on FPN expression. Additionally, HDAC2 knockdown alleviated I/R-induced myocardial injury and ferroptosis in mice. Moreover, H/R-induced HDAC2 upregulation transcriptionally inhibited FPN expression by reducing the H3K27Ac level in the FPN promoter region, but Dex therapy restored this impact via inhibition of HDAC2. As expected, HDAC2 overexpression partially reversed the inhibitory effect of Dex on H/R-mediated cardiomyocyte ferroptosis.

CONCLUSION

Dex alleviated H/R-mediated cardiomyocyte ferroptosis through regulating the HDAC2/FPN axis. Our findings lend theoretical support to the use of Dex in MIRI therapy.

Evaluation of diagnostic performances of Pro-neurotensin and Heart-type fatty acid binding protein as reliable biomarkers for cardiovascular diseases

AIM

In 2019, cardiovascular diseases accounted for 32% of global deaths. So, early detection of cardiac disorders is crucial. The study aimed to examine the suitability of Pro-neurotensin and Heart-type fatty acid binding protein as dependable biomarkers for cardiac patients with Heart failure as a primary diagnosis.

METHODOLOGY

The prospective study involved 204 Egyptian volunteers (100 cardiac patients and 104 controls) enrolled from El-Sahel Teaching Hospital in Cairo, Egypt, between October 2022 and May 2023. Inclusion criteria included a high risk of cardiovascular events with symptoms like a fast or irregular pulse, shortness of breath, and fatigue. Exclusion criteria included asymptomatic individuals, cognitive disorders, and psychiatric conditions. The Research Ethics Committee approved the protocol. The consultant conducted a clinical examination of all patients and assessed their heart state. Serum ProNT and H-FABP were detected using a kit for the sandwich ELISA technique.

RESULTS

ProNT and H-FABP were significantly elevated in patients compared to controls with p < 0.001. Demonstrated sensitivity of 81% and 84%, with a specificity of 89% and 91%, respectively.

CONCLUSION

Elevated ProNT and H-FABP levels are associated with severe CVDs, suggesting their potential as diagnostic biomarkers for patients, specifically those with heart failure, as a primary characteristic.

Chinese Visceral Adiposity Index Trajectory and Stroke in Prediabetes and Diabetes: A Prospective Cohort Study

AIMS

Stroke is a common diabetic complication, by which the Chinese visceral adiposity index (CVAI) is confirmed as a better predictor of visceral fat. However, the relationship between CVAI change and the stroke risk among patients with diabetes and prediabetes remains unclear. Therefore, we aimed to examine the association of CVAI trajectory with the risk of stroke.

MATERIALS AND METHODS

This prospective cohort study included 11,339 patients with prediabetes and diabetes from the Kailuan study. These participants had complete repeated metabolic and body measurements that formed the continuous CVAI records. The stroke cases were identified by medical records. Latent mixture modelling was conducted to fit four groups of CVAI trajectories. Cox proportional hazard regression models were used to examine the associations between CVAI trajectories and the risk of stroke and its subtypes.

RESULTS

Four distinct CVAI trajectories were identified: the low-stable, moderate low-stable, moderate high-stable, and high-increasing groups. Compared with low-stable CVAI, moderate high-stable (HR: 1.50, 95%CI: 1.10-2.04) and high-increasing CVAI (HR: 2.15, 95%CI: 1.49-3.10) were positively associated with the risk of stroke. Similarly, moderate high-stable (HR: 1.70, 95%CI: 1.21-2.39) and high-increasing CVAI trajectory groups (HR: 2.53, 95%CI: 1.71-3.73) had an increased risk of ischaemic stroke compared with the low-stable CVAI group. However, a significant association was not found between CVAI trajectory and risk of haemorrhage stroke.

CONCLUSION

A long-term elevated CVAI is associated with a higher risk of stroke, especially ischaemic stroke. This finding suggests the health benefits of low CVAI levels and the importance of regular surveillance among patients with prediabetes and diabetes.

Effects of Diabetes and Hyperlipidemia in Physiological Conditions - A Review

BACKGROUND

Diabetes mellitus (DM) is an autoimmune manifestation defined by persistent hyperglycemia and alterations in protein, fatty substances, and carbohydrate metabolism as an effect of problems with the secretion of insulin action or both. Manifestations include thirst, blurred eyesight, weight loss, and ketoacidosis, which can majorly lead to coma. There are different types of diabetes according to class or by cellular level. They are interrelated with hyperlipidemia as they are involved in the metabolism and regulation of physiological factors. Most parameters are seen at cellular or humoral levels, yet the underlying concern remains the same.

OBJECTIVE

To create a systematic correlation between the disease and locate the exact mechanism and receptors responsible for it. So, this article covers a proper way to resolve the conditions and their manifestation through literacy and diagrammatic.

CONCLUSION

Hence, this will be an insight for many scholars to understand the exact mechanism involved in the process.

Epicardial Adipose Tissue and Left Ventricular Hypertrophy in Hypertensive Patients With Preserved Ejection Fraction: A Multicenter Retrospective Cohort Study

This study aimed to investigate the correlation of the increased volume index of epicardial adipose tissue (EAT) and left ventricular hypertrophy (LVH) in patients with Hypertension (HTN). A total of 209 HTN patients and 50 healthy controls, who underwent cardiovascular magnetic resonance (CMR) at two medical centers in China between June 2015 and October 2024, were enrolled for this study. Postprocessing and imaging analysis were conducted and EAT measurements were performed. Restricted cubic splines (RCS) were used to explore the potential relationship with LVH. Binary logistic regression models and mediation analyses were employed to evaluate the association between EAT volume and CMR parameters as well as LVH. Hypertensive patients with LVH exhibited larger indexed EAT volumes, more pronounced diffuse fibrosis, and reduced left ventricular strain compared to hypertensive patients without LVH (all p < 0.001), with results remaining stable after adjusting for confounding factors. The variables that were significant in the univariate regression were included in the multivariate logistic regression model, indicating that indexed EAT volume (p = 0.001), extracellular volume (ECV) (p = 0.012), and global longitudinal strain (GLS) (p = 0.024) were independently associated with LVH. These associations remained stable after adjusting for confounding factors. Mediation analysis further revealed that the relationship between increased EAT volume and LVH was mediated by ECV, native T1, GLS, global circumferential strain (GCS), and global radial strain (GRS) (p < 0.05). These findings imply that EAT is independently linked to LVH in hypertensive patients. The association between EAT and LVH in hypertensive patients may be mediated by myocardial fibrosis or dysfunction.

The association between the metabolic score for insulin resistance and mortality in patients with cardiovascular disease: a national cohort study

Background

The metabolic score for insulin resistance (METS-IR) is a novel index for evaluating insulin resistance and identifying high-risk cardiovascular disease (CVD) patients. This study aims to assess the prognostic value of METS-IR in predicting mortality risk in CVD patients.

Methods

We analyzed data from 2,515 CVD patients in the National Health and Nutrition Examination Survey (NHANES). Associations between METS-IR and all-cause mortality and cardiovascular mortality were evaluated using multivariable Cox proportional hazards models and restricted cubic splines (RCS). Threshold effects and sensitivity analyses were conducted to ensure robustness.

Results

Over a median follow-up of 91.4 months, 1,090 patients died, including 447 from cardiovascular causes. A U-shaped relationship was identified between lnMETS-IR and all-cause and cardiovascular mortality, with thresholds at 3.70 and 3.67. Below thresholds, an increase of lnMETS-IR was associated with a 75% reduction in the risk of all-cause mortality (HR: 0.25, 95% CI: 0.14-0.46) and a 79% reduction in the risk of cardiovascular mortality (HR: 0.21, 95% CI: 0.07-0.56). While above thresholds, an increase of lnMETS-IR was associated with a 180% increase in the risk of all-cause mortality (HR: 2.80, 95% CI: 1.61-4.88) and a 233% increase in the risk of cardiovascular mortality (HR: 3.33, 95% CI: 1.43-7.75).

Conclusions

This study identified a U-shaped association between lnMETS-IR and mortality among CVD patients, underscoring the potential of METS-IR as a valuable prognostic marker for mortality risk in patients with CVD.

Psychological stress among hypertensive male patients in Jordan: prevalence and associated factors

BACKGROUND

Hypertension is a global, modifiable risk factor for cardiovascular and cerebrovascular disorders, imposing a significant burden due to its high mortality and morbidity rates. This study aimed to assess the prevalence and severity of psychological stress among hypertensive patients in Jordan and identify the factors associated with psychological stress.

METHODS

This descriptive, cross-sectional study was conducted on hypertensive patients at three community healthcare clinics in Jordan from May to July 2024. A sample of 276 hypertensive male patients was randomly selected, representing 85% of the total patients in the selected clinics. Patients were selected via systematic random sampling. A self-administered questionnaire on psychological stress using the Depression, Anxiety, and Stress Scale (DASS-42) was employed. The data were collected through Google Forms and analyzed using SPSS statistical software (version 27).

RESULTS

A total of 276 hypertensive males participated in the study, and the mean score of psychological stress was 16.02(± 7.59). The prevalence of psychological stress was 55.1%, with 60 (39.5%) experiencing mild stress and 57 (37.5%) experiencing moderate stress. Chronic diseases and inadequate exercise were significantly associated with psychological stress (p-values: 0.003 and < 0.001, respectively). Participants reporting stressful work were more than four times more likely to experience psychological stress than those who did not report work-related stress (OR = 4.06; 95% CI: 2.00-8.25; p < 0.001). A stressful home environment and insufficient sleep were also significantly associated with psychological stress (p = 0.026 and p < 0.001, respectively).

CONCLUSIONS

The results highlight a strong association between psychological stress and hypertension. Factors such as chronic diseases, insufficient exercise, occupational stress, a stressful home environment, and inadequate sleep contribute to psychological stress among hypertensive patients. These findings provide valuable insights for healthcare providers in developing tailored interventions to alleviate stress while managing hypertension.

Characteristics of Mortality After Endovascular Thrombectomy in Patients with Acute Ischemic Stroke

Purpose

Despite significant advancements in the treatment of acute ischemic stroke (AIS) with endovascular thrombectomy (EVT), post-EVT mortality remains a considerable concern. However, there is a lack of real-world epidemiological data delineating the characteristics of mortality for EVT, particularly in recent years following the widespread promotion of EVT treatment for stroke patients.

Methods

This multicenter, retrospective study collected data from 721 AIS patients who died following EVT across 33 hospitals in Sichuan Province, China, from January 2019 to September 2022. The analysis sought to identify the primary causes of death within 30 days post-EVT and explore their related clinical features.

Results

The leading causes of death were malignant cerebral edema (MCE) in 365 patients (50.6%), pneumonia in 180 patients (25%), and symptomatic intracranial hemorrhage (sICH) in 94 patients (13%). MCE was the predominant cause of death in anterior circulation strokes, while pneumonia prevailed in posterior circulation strokes. MCE was also the primary cause of death within one week post-EVT, but pneumonia became increasingly dominant over time. Large vessel occlusion and lower reperfusion success rate were significantly correlated with MCE. Advanced age increases the risk of death from pneumonia. Tandem occlusion and procedural complications tend to correlate with mortality from sICH.

Conclusion

This study revealed that the principal causes of death after EVT included MCE, sICH, and pneumonia. MCE was found to be correlated with unsuccessful reperfusion. sICH was associated with procedural complications and the operators' experience. Pneumonia was linked to post-EVT management, particularly for those who survived for one week.

Additive interaction of family medical history of cardiovascular diseases with hypertension and diabetes on the diagnosis of cardiovascular diseases among older adults in India

Introduction

The present study aimed to examine the additive interaction of family medical history of cardiovascular disease (CVD) and self-reported hypertension and diabetes on the diagnosis of CVD among older adults aged 45 years and above in India. A family medical history of CVD in individuals with hypertension and diabetes could identify a subpopulation with a higher risk of CVD.

Methods

The study used the data from the Longitudinal Ageing Study in India (LASI) Wave 1 (2017-2018). The total sample size for the study was 58,734 older adults aged 45 years and above. An additive model was applied to determine the additive interaction effect of the family medical history of CVD with hypertension and diabetes on the diagnosis of CVD by calculating three different measures of additive interaction: the relative excess risk due to interaction (RERI), attribution proportion due to interaction (AP), and synergy index (S).

Results

The prevalence of CVD was higher among hypertensive individuals with a family medical history of CVD (18.6%) than individuals without the coexistence of family medical history of CVD and hypertension (4.7%), and hypertensive individuals without family medical history of CVD (11.3%). On the other hand, the prevalence of CVD was higher among individuals with diabetes and family history of CVD (20.5%) than individuals without the coexistence of family history of CVD and diabetes (5.0%). Individuals with parental and sibling medical history had two times higher odds of having chronic heart diseases and strokes, respectively than those without parental and sibling history. In the adjusted model, RERI, AP, and S for CVD were 2.30 (95% CI: 0.87-3.74), 35% (0.35; 95% CI: 0.20-0.51), and 1.71 (95% CI: 1.27-2.28) respectively, demonstrating significant positive interaction between family medical history and hypertension on the diagnosis of cardiovascular diseases.

Conclusions

The present study revealed that in the additive model, the interaction effects of family medical history and hypertension were significantly positive on cardiovascular diseases even after adjustment with potential confounding factors. Therefore, it is crucial to consider the presence of family medical history of CVD among individuals with hypertension and diabetes measured in research and clinical practice.

Mechanical Thrombectomy for Acute Ischemic Stroke in Nonagenarians: A Dilemma in Treatment Approach

Stroke is one of the major causes of mortality and morbidity, particularly among the elderly population. As the general population ages, cerebrovascular disease is anticipated to increase in prevalence. Strokes can manifest as either hemorrhagic or ischemic events. While mechanical thrombectomy is efficacious in the treatment of major arterial occlusion, many studies have excluded nonagenarians due to anticipated poor functional outcomes. The functional prognosis in nonagenarians is influenced by various factors, including procedural challenges related to vessel tortuosity, collateral circulation status, and multiple medical comorbidities. Herein, we report a case of acute ischemic stroke (AIS) in a nonagenarian male with major arterial occlusion successfully managed via mechanical thrombectomy, resulting in an excellent post-procedural outcome at the three-month follow-up.

Indole-3-Carboxaldehyde Inhibits Inflammatory Response and Lipid Accumulation in Macrophages Through the miR-1271-5p/HDAC9 Pathway

Indole-3-carboxaldehyde (ICA), a microbiota-derived tryptophan metabolite, has been reported to protect against atherosclerosis. However, the molecular mechanisms for its atheroprotective effect remain largely unknown. This study aimed to explore the influence of ICA on lipid accumulation and inflammatory response in THP-1 macrophage-derived foam cells. Our results showed that administration of ICA upregulated the expression of miR-1271-5p, ATP binding cassette transporter A1 (ABCA1) and ABCG1, downregulated histone deacetylase 9 (HDAC9) expression and inhibited macrophage lipid accumulation. ICA treatment also facilitated macrophage polarisation to the M2 phenotype and alleviated inflammatory response, as evidenced by decreased IL-6 levels and increased IL-10 levels. HDAC9 was identified as a direct target of miR-1271-5p. HDAC9 overexpression or miR-1271-5p knockdown decreased the effect of ICA on ABCA1 and ABCG1 expression as well as inflammatory response. Taken together, these results suggest that ICA can suppress lipid accumulation and mitigate inflammatory response in macrophages by activating the miR-1271-5p/HDAC9 signalling cascade, thereby providing new explanations for how ICA reduces atherosclerosis.

Combined Effects of Air Pollution and Changes in Physical Activity With Cardiovascular Disease in Patients With Dyslipidemia

BACKGROUND

Sedentary behavior elevates cardiovascular disease (CVD) risk in patients with dyslipidemia. Increasing physical activity (PA) is recommended alongside pharmacological therapy to prevent CVD, though benefits across environmental conditions are unclear.

METHODS AND RESULTS

We analyzed data from 113 918 newly diagnosed patients with dyslipidemia (2009-2012) without prior CVD, sourced from the Korea National Health Insurance Service. Ambient particulate matter (PM) 2.5 and PM10 levels were collected from the National Ambient Air Monitoring System in South Korea. Changes in PA, measured in metabolic equivalents of task-min/wk before and after dyslipidemia diagnosis, were evaluated for associations with air pollution levels and CVD risk using Cox proportional hazards regression. Patients were followed from January 1, 2013, until CVD onset, death, or December 31, 2021. Among patients exposed to low to moderate PM2.5 levels (≤25 μg/m3), increasing PA from inactive to ≥1000 metabolic equivalents of tasks-min/wk was associated with a lower risk of CVD (adjusted hazard ratio, 0.82 [95% CI, 0.70-0.97]; P for trend=0.022). In high PM2.5 (>25 μg/m3) conditions, increasing PA from inactive and decreasing PA from ≥1000 metabolic equivalents of task-min/wk was associated with reduced (P for trend=0.010) and elevated (P for trend=0.028) CVD risks, respectively. For PM10, increased PA was linked to reduced CVD risk (P for trend=0.002) and decreased PA to elevated risk (P for trend=0.042) in low to moderate PM10 (≤50 μg/m3) conditions, though benefits diminished at high PM10 (>50 μg/m3) exposures.

CONCLUSIONS

Promoting PA, while considering the high potential cardiovascular risk associated with air pollution, may be an effective intervention against CVD in patients with dyslipidemia.

Backward walking training is as effective as or better than forward walking training for improving walking speed after stroke: a systematic review with meta-analysis

OBJECTIVE

In people who have had stroke, are the effects of backward walking comparable with forward walking for improving walking (i.e. speed, cadence, and stride length)? Does the addition of backward walking to forward walking help improve the benefits of forward walking? Are any benefits maintained beyond intervention?

METHODS

A systematic review of randomized trials, with adults following stroke, was developed. The intervention of interest was backward walking training, delivered either as a solo intervention or in combination with forward walking training. The outcome measures of interest were walking speed, cadence, and stride length.

RESULTS

The effect of backward walking training is similar as or better than that of forward walking training for improving walking speed (MD 0.16 m/s, 95% CI 0.06 to 0.27), but results for cadence and stride length were very imprecise. The addition of backward walking training to forward walking training provided negligible effects on walking speed (MD 0.03 m/s, 95% CI 0.01 to 0.04), cadence (MD 5 steps/min, 95% CI 1 to 10), and stride length (MD 0.04 m, 95% CI -0.01 to 0.09). Maintenance of effects beyond the intervention period remains uncertain.

CONCLUSIONS

This review provided moderate-quality evidence that backward walking training is slightly better than forward walking training for improving walking speed after stroke, but not when it is additional to forward walking training. Large and well-designed trials are warranted to strengthen the evidence regarding backward walking training, especially in the subacute phase after stroke.

Modified-Mindfulness-Based Stress Reduction as a Treatment for Cognitive Recovery in Patients with Minor Stroke: a Randomized Controlled Pilot Study

Background

Well-developed rehabilitation paradigms exist for post-stroke language and motor impairments. However, no such recovery program has been identified for commonly disabling cognitive deficits in patients following minor stroke. Mindfulness Based Stress Reduction (MBSR) is thought to engage the frontal lobes, improving concentration and attention, and therefore may be an effective option.

Methods

We prospectively enrolled a cohort of patients with subacute minor stroke and randomized them to either an 8-week online modified-MBSR course or online traditional Stroke Support Group (SSG). All patients underwent a battery of cognitive tests and measures of patient reported outcomes (PROs) pre- and post-intervention. ANOVA was used to compare changes in scores over time across both groups, as well as a third group of control patients having received neither intervention (n=128).

Results

A total of 30 patients were randomized (n=16 for m-MBSR; n=14 for SSG). The average age of the cohort was 65.9 years. Both groups scored similarly on assessments one-month post-stroke and demonstrated increased T-scores on cognitive tasks at the 3-month visit. However, the m-MBSR group showed moderately elevated levels of improvement, specifically in processing speed, executive, and global cognitive function. Level of engagement was not associated with better clinical scores, though was unexpectedly low for both groups.

Conclusions

m-MBSR appears to modestly improve frontal lobe activity and demonstrates some success in increasing cognitive performance. However, further studies are needed to determine if it is more efficacious in the chronic stage of recovery when more patients are able to fully engage and actively participate.

Relationships between different trends of the Mediterranean diet and cardiovascular disease-related risk factors in China: results from the CHNS study, 1997-2009

Objectives

The present study aimed to explore the associations between Mediterranean diet trajectories (MDTs) and cardiovascular disease-related risk factors in Chinese adults.

Methods

A total of 4,332 participants from the China Health and Nutrition Survey (CHNS) were included in this study. A group-based trajectory model (GBTM) was used to explore Mediterranean diet trajectories (MDTs). Linear regression analyses were conducted to assess the association between Mediterranean diet trajectories and cardiovascular disease-related risk factors. Stratified analyses by gender were also performed.

Results

The following four groups were identified in the total population: Group 1 (Persistently low MDT, n = 292, 6.74%), Group 2 (Descent MDT, n = 537, 12.40%), Group 3 (Ascent MDT, n = 454, 10.48%), and Group 4 (Persistently high MDT, n = 3,049, 70.38%). Compared to the persistently low MDT (Group 1), both Group 2 and Group 4 were negatively related to low-density lipoprotein cholesterol (LDL-C) (Group 2: β = -0.23, 95% CI: -0.36 to -0.09, p = 0.001; Group 4: β = -0.25, 95% CI: -0.37 to -0.14, p < 0.001), total cholesterol (TC) (Group 2: β = -0.18, 95% CI: -0.32 to -0.04, p = 0.010; Group 4: β = -0.31, 95% CI: -0.43 to -0.19, p < 0.001), and uric acid (UA) (Group 2: β = -15.16, 95% CI: -28.66 to -2.56, p = 0.019; Group 4: β = -27.51, 95% CI: -38.77 to -16.25, p < 0.001) after adjusting for potential risk factors. Only Group 4 exhibited a negative relationship with triglycerides (TG) (β = -0.18, 95% CI: -0.34 to -0.02, p = 0.028) and blood glucose (β = -0.19, 95% CI: -0.37 to -0.02, p = 0.032).

Conclusion

Four MDTs were identified among the total participants, including men and women. These trajectories were summarized as persistently low MDT, ascent MDT, descent MDT, and persistently high MDT. Adherence to high MDTs could reduce the level of some CVD-related risk factors. The impact of the remote MD on CVD-related risk factors may be greater than that of the proximal MD.

Cardiovascular reactivity during conversations about discrimination is buffered by social support among U.S. Latines

Racial discrimination is conceptualized as an acute and chronic stressor. Like other acute stressors, lab-based studies demonstrate acute effects of discrimination-related stressors on stress-related cardiovascular outcomes, including total cardiac output, blood pressure, and indices of sympathetic and parasympathetic nervous system activity. Critically, it is important to understand how individual and social factors buffer the experience of race-related acute stress. The current study extends existing work by measuring cardiovascular indices of stress during conversations about racial/ethnic discrimination and examines the moderating role of social support. Latine/Hispanic participants (N = 97) talked about personal discrimination experiences with either a close other or a research assistant they had never previously met. Participants in both conditions exhibited cardiovascular reactivity indicative of stress during the conversation. Additionally, patterns of reactivity reflected a more adaptive stress response and recovery profile when participants talked about discriminatory experiences with a close other relative to a stranger (less parasympathetic withdrawal during the stressor and more parasympathetic rebound during recovery). These patterns are consistent with a stress buffering account of social support, which suggests social bonds and community-level support are critical to consider in interventions to mitigate the harms of experiencing discrimination and prevent chronic health disparities.

Advances in xenogeneic donor decellularized organs: A review on studies with sheep and porcine-derived heart valves

Heart valve replacement surgeries are performed on patients suffering from abnormal heart valve function. In these operations, the problematic tissue is replaced with mechanical valves or with bioprosthetics that are being developed. The thrombotic effect of mechanical valves, reflecting the need for lifelong use of anticoagulation drugs, and the short-lived nature of biological valves make these two types of valves problematic. In addition, they cannot adapt to the somatic growth of young patients. Although decellularized scaffolds have shown some promise, a successful translation has so far evaded. Although decellularized porcine xenografts have been extensively studied in the literature, they have several disadvantages, such as a propensity for calcification in the implant model, a risk of porcine endogenous retrovirus (PERV) infection, and a high xenoantigen density. As seen in clinical data, it is clear that there are biocompatibility problems in almost all studies. However, since decellularized sheep heart valves have not been tried in the clinic, a large data pool could not be established. This review compares and contrasts decellularized porcine and sheep xenografts for heart valve tissue engineering. It reveals that decellularized sheep heart valves can be an alternative to pigs in terms of biocompatibility. In addition, it highlights the potential advantages of bioinks derived from the decellularized extracellular matrix in 3D bioprinting technology, emphasizing that they can be a new alternative for the application. We also outline the future prospects of using sheep xenografts for heart valve tissue engineering.

Menstrual cycle and the protective effects of remote ischemic preconditioning against endothelial ischemia/reperfusion injury: comparison with postmenopausal women

The aim of this study was to determine whether the capacity of remote ischemic preconditioning (IPC) against endothelial ischemia/reperfusion (I/R) injury changes across the menstrual cycle in premenopausal women and to compare IPC responses to postmenopausal women. Thirty-five women were studied (22 premenopausal/13 postmenopausal). Changes in endothelial function were determined during the early follicular vs. the late follicular phase (after positive urine ovulation test; Study 1), vs. the mid-luteal phase (after positive urine progesterone test; Study 2), and vs. estrogen-deficient postmenopausal women; Study 3). Endothelium-dependent vasodilation was assessed by the forearm blood flow (FBF) to reactive hyperemia with/without I/R injury with remote IPC (3 × 5 min cycles of upper arm ischemia). In the premenopausal women, peak FBF responses during the early follicular phase were blunted 20% (P < 0.0001) with I/R injury (from baseline: 23.4 ± 6.2 to 19.5 ± 4.9 mL/100 mL tissue/min) compared with the late follicular/mid-luteal phases despite IPC. In postmenopausal women, peak FBF was diminished (from: 21.1 ± 5.1 to 17.2 ± 4.4 mL/100 mL tissue/min), and total FBF (area under the curve) was decreased a third (-32%; P < 0.001) with I/R injury. Protection from I/R injury was preserved during the late follicular (from baseline: 21.7 ± 5.3 to 24.8 ± 5.9 mL/100 mL tissue/min; P = 0.109) and mid-luteal phases (from: 25.1 ± 3.9 to 27.2 ± 5.7 mL/100 mL tissue/min; P = 0.267). Reduced estrogen during the early follicular phase and the rise in estrogen associated with ovulation and the mid-luteal phase may contribute to changes in IPC-mediated protection in premenopausal women and shed light on how cardioprotection may change with ovarian hormone deficiency with the menopause transition.NEW & NOTEWORTHY The capacity of remote ischemic preconditioning to protect against vascular endothelial ischemia/reperfusion injury varies widely across the phases of the menstrual cycle in healthy premenopausal women. Robust protection was afforded during the late follicular and mid-luteal phases. In contrast, weakened protection was demonstrated during the early follicular phase, with a level of impairment similar to estrogen-deficient postmenopausal women.

Experiences With mHealth Use Among Patient-Caregiver Dyads With Chronic Heart Failure: Qualitative Study

BACKGROUND

Chronic heart failure has become a serious threat to the health of the global population, and self-management is key to treating chronic heart failure. The emergence of mobile health (mHealth) provides new ideas for the self-management of chronic heart failure in which the informal caregiver plays an important role. Current research has mainly studied the experiences with using mHealth among patients with chronic heart failure from the perspective of individual patients, and there is a lack of research from the dichotomous perspective.

OBJECTIVE

The aim of this study was to explore the experiences with mHealth use among patients with chronic heart failure and their informal caregivers from a dichotomous perspective.

METHODS

This descriptive phenomenological study from a post-positivist perspective used a dyadic interview method, and face-to-face semistructured interviews were conducted with patients with chronic heart failure and their informal caregivers. Data were collected and managed using NVivo 12 software, and data analysis used thematic analysis to identify and interpret participants' experiences and perspectives. The thematic analysis included familiarizing ourselves with the data, generating initial codes, searching for themes, reviewing themes, defining and naming themes, and producing the report.

RESULTS

A total of 14 dyads of patients with chronic heart failure and their informal caregivers (13 men and 15 women) participated in this study, including 3 couples and 11 parent-child pairs. We constructed 4 key themes and their subthemes related to the experiences with mHealth use: (1) opposing experiences with mHealth as human interaction or trauma (great experience with mHealth use; trauma), (2) supplement instead of replacement (it is useful but better as a reference; offline is unavoidable sometimes), (3) both agreement and disagreement over who should be the adopter of mHealth (achieving consensus regarding who should adopt mHealth; conflict occurs when considering patients as the adopter of mHealth), (4) for better mHealth (applying mHealth with caution; suggestions for improved mHealth).

CONCLUSIONS

This study reported that the experiences with mHealth use among patients with chronic heart failure and their informal caregivers were mixed, and it highlighted the human touch of mHealth and the importance of network security. These results featured mHealth as a complement to offline hospitals rather than a replacement. In the context of modern or changing Chinese culture, we encourage patients to use mHealth by themselves and their informal caregivers to provide help when necessary. In addition, we need to use mHealth carefully, and future mHealth designs should focus more on ease of use and be oriented more toward older adults.

Clinical decision-making in patients with non-ST-segment-elevation myocardial infarction: more than risk stratification

OBJECTIVE

This study aims to explore the association between risk stratification and total occlusion (TO) of the culprit artery and multivessel disease (MVD) in patients with non-ST-segment-elevation myocardial infarction (NSTEMI) and to obtain more data on clinical decision-making in addition to risk stratification.

METHODS

We retrospectively collected data from 835 patients with NSTEMI admitted to our hospital between 1 January 2016 and 1 August 2022. All patients underwent percutaneous coronary intervention (PCI) within 72 h of admission. We excluded patients with a history of cardiac arrest, myocardial infarction, coronary artery bypass grafting, or PCI. Univariate and multivariate regression analyses were performed to determine the predictors of acute TO and MVD.

RESULTS

A total of 349 (41.8%) patients presented with a TO culprit vessel, whereas 486 (58.2%) had a patent culprit vessel. Thrombolysis in myocardial infarction (TIMI) and Global Registry of Acute Coronary Events (GRACE) risk stratifications were similar between the two groups of patients (P = 0.712 and 0.991, respectively). The TO infarct vessel was more commonly observed in the left circumflex artery. Patients with TO were more likely to develop MVD (P = 0.004). Univariate and multivariate linear regression analyses were performed to evaluate the role of variables in the presence of TO and MVD in patients with NSTEMI. Regional wall motion abnormalities (RWMAs) [odds ratio (OR) = 4.022; confidence interval (CI): 2.782-5.813; P < 0.001] were significantly linked to TO after adjusting for potentially related variables. Furthermore, age (OR = 1.032; CI: 1.018-1.047; P < 0.001), hypertension (OR = 1.499; CI: 1.048-2.144; P = 0.027), and diabetes mellitus (OR = 3.007; CI: 1.764-5.125; P < 0.001) were independent predictors of MVD in patients with NSTEMI. TIMI and GRACE risk scores were related to MVD prevalence in the multivariate logistic regression model. Patients with a TO culprit vessel had a higher risk of out-of-hospital cardiac death after a 2-year follow-up compared with those without a TO culprit vessel (P = 0.022).

CONCLUSION

TIMI and GRACE risk scores were not associated with a TO of the culprit artery; however, they correlated with the prevalence of MVD in patients with NSTEMI. RWMA is an independent predictor of acute TO in patients with NSTEMI. Patients with a TO culprit vessel had worse clinical outcomes than those without a TO culprit vessel.

Effect of traditional Chinese exercises on the physical and mental health of stroke patients: a meta-analysis

Background

This meta-analysis aimed to investigate the effects of traditional Chinese exercises on stroke and explore the dose-response relationship between the type of exercise and exercise duration with respect to physical and mental health.

Methods

We searched PubMed, Web of Science, EBSCO, China National Knowledge Infrastructure (CNKI), Wan Fang Database, and China Science and Technology Journal Database to identify published randomized controlled trials (RCTs) related to stroke patients and traditional Chinese exercise that met the evaluation criteria, from the inception of the database until September 2022. After assessing the quality of the literature, we used RevMan5.4 for data analysis.

Results

A total of 27 RCTs were included. The results of the meta-analysis revealed that motor function [MD = 4.79, 95% CI: (4.14, 5.43), p < 0.001], balance function [MD = 5.25, 95% CI: (3.93, 6.56), p < 0.001], and mental health [MD = -2.42, 95% CI: (-3.92 to -0.92), p = 0.002] were significantly better in the experimental group than in the control group.

Conclusion

Traditional Chinese exercises have a positive effect on the physical and mental health of stroke patients, with the most significant benefit observed in balance function. While traditional Chinese exercises improve exercise capacity and mental health in stroke patients, these improvements are not directly correlated with longer practice time, and there appear to be certain limitations regarding duration.

Effect of non-invasive brain stimulation on post-stroke cognitive impairment: a meta-analysis

Background

Previous studies have suggested that repetitive transcranial magnetic stimulation (rTMS) may be an effective and safe alternative treatment for post-stroke cognitive impairment (PSCI). Similarly, the application of transcranial direct current stimulation (tDCS) during stroke rehabilitation has been shown to improve cognitive function in PSCI patients. However, there have been conflicting results from some studies. Therefore, this study aims to conduct a meta-analysis to evaluate the effects of tDCS and rTMS on PSCI.

Methods

The meta-analysis search for articles published from the initial availability date to 5 February 2024 in databases. The extracted study data were entered into STATA 12.0 software for statistical analysis.

Results

This meta-analysis provides evidence that both rTMS and tDCS have a positive impact on general cognitive function in PSCI patients [immediate effect of rTMS: standard mean difference (SMD) = 2.58, 95% confidence interval (CI) = 1.44 to 3.71; long-term effect of rTMS: SMD = 2.33, 95% CI = 0.87-3.78; immediate effect of tDCS: SMD = 2.22, 95% CI = 1.31-3.12]. Specifically, rTMS was found to significantly improve attention, language, memory, and visuospatial functions, while it did not show a significant therapeutic effect on executive function (attention: SMD = 3.77, 95% CI = 2.30-5.24; executive function: SMD = -0.52, 95% CI = -3.17-2.12; language: SMD = 3.43, 95% CI = 1.50-5.36; memory: SMD = 3.52, 95% CI = 1.74-5.30; visuospatial function: SMD = 4.71, 95% CI = 2.61-6.80). On the other hand, tDCS was found to significantly improve executive and visuospatial functions but did not show a significant improvement in attention function and memory (attention: SMD = 0.63, 95% CI = -0.30-1.55; executive function: SMD = 2.15, 95% CI = 0.87-3.43; memory: SMD = 0.99, 95% CI = -0.81-2.80; visuospatial function: SMD = 2.64, 95% CI = 1.04-4.23).

Conclusion

In conclusion, this meta-analysis demonstrates that both rTMS and tDCS are effective therapeutic techniques for improving cognitive function in PSCI. However, more large-scale studies are needed to further investigate the effects of these techniques on different cognitive domains in PSCI.

Polyglycerol Sebacate/polycaprolactone/reduced graphene oxide composite scaffold for myocardial tissue engineering

The aim of this research was to fabricate and evaluate polyglycerol sebacate/polycaprolactone/reduced graphene oxide (PGS-PCL-RGO) composite scaffolds for myocardial tissue engineering. Polyglycerol sebacate polymer was synthesized using glycerol and sebacic acid prepolymers, confirmed by Fourier-transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). Six PGS-PCL-RGO composite scaffolds (S1-S6) with various weight ratios were prepared in chloroform (CF) and acetone (Ace) solvents at 8 CF:2Ace and 9 CF:1Ace volume ratios, using the electrospinning method at a rate of 1 ml/h and a voltage of 18 kV. The scaffolds' chemical composition and microstructure were characterized by FTIR, XRD, and scanning electron microscopy (SEM). Further investigations included tensile testing, contact angle testing, four-point probe testing for electrical conductivity, degradation testing, and cytotoxicity testing (MTT). The results showed that adding 2%wt RGO to the composite scaffold decreased fiber diameter and degradation rate, while increasing electrical conductivity and ductility. The 33%PGS-65%PCL-2%RGO (S3) composite scaffold exhibited the lowest degradation rate (23.87 % over 60 days) and the highest electrical conductivity (51E-3 S/m). Mechanical evaluations revealed an elastic modulus of 2.46 MPa and elongation of 62.43 %, aligning closely with the heart muscle's elastomeric properties. The contact angle test indicated that the scaffold was hydrophilic, with a water contact angle of 61 ± 2°. Additionally, the cell toxicity test confirmed that scaffolds containing RGO were non-toxic and supported good cell viability. In conclusion, the 33%PGS-65%PCL-2%RGO composite scaffold exhibits mechanical and structural properties similar to heart tissue, making it an ideal candidate for myocardial tissue engineering.

Curve-centered plaques raise the risk of peri-operative neurological and cardiovascular complications during angioplasty and stenting for severe carotid stenosis

Introduction

Carotid artery stenting is an alternative interventional treatment to carotid endarterectomy. However, preprocedural considerations and anatomical risk factor analyses for carotid artery stenting are currently insufficient. Therefore, we investigated the high-risk anatomical appearance of carotid artery stenting from the neurointerventionist perspective to predict periprocedural complications.

Materials and methods

We retrospectively reviewed patients with carotid stenosis who underwent carotid artery stenting at a comprehensive stroke center between January 2012 and December 2021. We compared the demographic characteristics, medical history, and anatomical appearance of the stenotic segment in patients with and without complications.

Results

We analyzed a total of 148 patients (64 women [43.2%]; median age, 73.0 [interquartile range, 65.5-79.0]). Complications occurred in 39 of the 148 patients, primarily minor and transient. Of baseline or procedural characteristics, a high initial National Institutes of Health Stroke Scale score (p = 0.04), symptomatic stenosis (p = 0.01), and curve-centered plaque of the proximal ICA (p = 0.01) were significantly associated with carotid artery stenting complications in unadjusted analysis. Curve-centered plaque remained an independent risk factor for carotid artery stenting complications after adjustment (odds ratio 2.23[1.02-4.88], p = 0.04).

Conclusion

High-risk vascular anatomical features, such as curve-centered plaque, are associated with a high frequency of periprocedural complications of carotid artery stenting. Tailored patient selection for carotid stenosis is crucial to prevent complications. Patients with curve-centered plaque should consider alternative treatment options such as carotid endarterectomy to achieve optimal clinical results.

Development and validation of a prediction model for heart failure in patients with heart valvular regurgitation

AIMS

Patients with heart valvular regurgitation is increasing; early screening of potential patients developing heart failure (HF) is crucial.

METHODS

From 1 November 2019 to 31 October 2023, a total of 509 patients with heart valvular regurgitation hospitalized in the Department of Cardiovascular Disease of the First Affiliated Hospital of Guangzhou University of Traditional Medicine were enrolled. Three hundred fifty-six cases were selected as the training set for modelling, and 153 cases were selected as the validation set for the internal validation of the model.

RESULTS

A predictive model of heart failure with the following nine risk factors was developed: atrial fibrillation (AF), pulmonary infection (PI), coronary artery disease (CAD), creatinine (CREA), low-density lipoprotein cholesterol (LDL-C), d-dimer (DDi), left ventricular end-diastolic diameter (LVEDd), mitral regurgitation (MR) and aortic regurgitation (AR). The model was evaluated by the C-index [the training set: area under curve (AUC) 0.937, 95% confidence interval (CI) 0.911-0.963; the validation set: AUC 0.928, 95% CI 0.890-0.967]. Hosmer-Lemeshow test (the training set: χ2 10.908, P = 0.207; the validation set: χ2 4.896, P = 0.769) revealed that both the training and validation sets performed well in terms of model differentiation and calibration. Decision curve analysis showed that both the training and validation sets have higher net benefits, indicating that the model has good utility. Ten-fold cross-validation showed that the training set has high similarities with the validation set, which means that the model has good stability.

CONCLUSIONS

The occurrence of heart failure in patients with valvular regurgitation has a significant correlation with AF, PI, CAD, CREA, LDL-C, DDi, LVEDd, MR and AR. Based on these risk factors, a prediction model for heart failure was developed and validated, which showed good differentiation and utility, high accuracy and stability, providing a method for predicting heart failure.

Determinants of adherence to post-stroke/transient ischemic attack secondary prevention medications: A cohort study

BACKGROUND

Adherence to post-stroke secondary prevention medications mitigates recurrence risk. This study aimed to measure adherence to secondary prevention medications during 3 years post-ischemic stroke/transient ischemic attack, using prescription and dispensing data, and identify factors associated with suboptimal adherence.

METHODS

This multicenter, prospective, cohort study involved patients from the STROKE 69 cohort, which included all consecutive patients with suspected acute stroke admitted between November 2015 and December 2016 to any emergency department or stroke center in the Rhône area in France. Prescription data for antihypertensive agents, antidiabetic agents, lipid-lowering drugs, and antithrombotics were collected. Dispensing data were provided by the French regional reimbursement database. Adherence was calculated using the continuous medication acquisition index. Associations between suboptimal adherence and potential influencing factors across the World Health Organization's five dimensions were explored through univariate and multivariate analyses.

RESULTS

From 1512 eligible patients, 365 were included. Optimal adherence to overall treatment (≥90%) was observed in 61%, 62%, and 65% of patients in the first, second, and third years, respectively. Education level (high school diploma or higher: OR = 3.24, 95% CI [1.49; 7.36]) and depression (Hospital Anxiety and Depression Scale-Depression scores 8-10: OR = 1.90, 95% CI [1.05; 3.44]) were significantly associated with suboptimal adherence.

CONCLUSIONS

Overall adherence to secondary prevention medications was fairly good. Having an initial diagnosis of transient ischemic attack, a high level of education, or depression was associated with increased odds of suboptimal adherence, while having a history of heart rhythm disorder was associated with lower odds.

Outcomes of Percutaneous Coronary Intervention in Patients With Prior Coronary Artery Bypass Grafting: A Two-Country Perspective

BACKGROUND

Coronary artery disease (CAD) is a leading cause of mortality worldwide. Treatments such as percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) are crucial for managing CAD. While CABG is often preferred for complex cases, many patients require PCI due to graft failure or new blockages post-CABG. This study evaluates PCI outcomes in Pakistani and Saudi patients with prior CABG, addressing the scarcity of regional data.

OBJECTIVE

The primary objective was to measure the success rate of PCI in post-CABG patients, defined as achieving less than 30% residual stenosis without major complications. Secondary objectives included assessing the incidence of restenosis, repeat revascularization, and major adverse cardiac events (MACEs) over one year.

METHODS

This one-year prospective cohort study was conducted at multiple tertiary care hospitals in Pakistan and Saudi Arabia, involving 246 participants aged 18 years and older who had previously undergone CABG. Participants underwent PCI using standard procedures. Data were collected on demographic information, clinical characteristics, procedural details, and follow-up outcomes. Statistical analysis was performed using IBM SPSS Statistics for Windows, Version 25 (Released 2017; IBM Corp., Armonk, New York, United States), with descriptive statistics summarizing the baseline characteristics. The chi-square test or Fisher's exact test compared categorical variables, and the t-test or Mann-Whitney U test was used for continuous variables. A p-value of less than 0.05 was considered statistically significant.

RESULTS

 The mean age of the participants was 63.5 ± 10.2 years, with 73.2% being male. The PCI success rate was 91.5% (95% CI: 88.2-94.8%), with most patients achieving less than 30% residual stenosis. There were 15 cases (6.1%) of MACEs, including five myocardial infarctions (2.0%) and 10 urgent revascularizations (4.1%). Restenosis occurred in 20 patients (8.1%; 95% CI: 4.7-11.5%), and repeat revascularization was required in 18 patients (7.3%; 95% CI: 4.0-10.6%). Kaplan-Meier survival analysis indicated no significant difference in MACE-free survival between patients with and without restenosis (log-rank test, p=0.423).

CONCLUSION

The high success rate of PCI in post-CABG patients across both Pakistan and Saudi Arabia suggests that it is a viable option even in complex cases. These findings can inform clinical practice, emphasizing the importance of consistent follow-up and tailored interventions to enhance patient outcomes.

The Impact of Hormone Replacement Therapy on the Risk of Heart Failure in Postmenopausal Women: A Meta-Analysis of Clinical and Observational Studies

PURPOSE

The relationship between heart failure (HF) and hormone replacement therapy (HRT) in postmenopausal women remains unclear. This paper aimed to elucidate the association between HRT and HF outcomes in postmenopausal women by scrutinizing evidence from clinical trials and observational studies.

METHODS

The meta-analysis was systematically executed following the PRISMA guidelines to include studies identified from the electronic databases, including PubMed, EMBASE, EBSCO, ICTRP, and NIH clinical trials. The primary endpoint of the effect comprised risk ratios (RR) for HF incidence and mortality, attended by 95% confidence intervals (CIs). The risk of bias was assessed employing the Cochrane Risk of Bias 2 (RoB2) tool for clinical trials and the Newcastle-Ottawa Scale (NOS) for observational studies.

RESULTS

The search yielded a total of eight reports, originating from six individual studies, for inclusion in the current study, and 25 047 participants were included. The meta-analysis demonstrated no remarkable association between HRT and the incidence of HF in postmenopausal women (RR: 1.07, 95% CI: 0.91-1.25, p = 0.37). However, a significant reduction in all-cause mortality was observed among post-menopausal HF patients who received HRT (RR: 0.65, 95% CI: 0.49-0.87, p = 0.003). In age-related subgroup analyses, no significant change in the risk of HF was noticed among participants on HRT.

CONCLUSIONS

The findings of this paper demonstrate that HRT use is not associated with a significant increase in the risk of incident HF. This meta-analysis also suggests a benefit in all-cause mortality when HRT is administered to postmenopausal women with HF.

Life's Essential 8 and Incident Cardiovascular Disease in U.S. Women With Breast Cancer

Background

Relationships between lifestyle risk factors and cardiovascular disease (CVD) risk in women with breast cancer (BC) are underexplored.

Objectives

To evaluate the incidence of CVD in relation to the Life's Essential 8 (LE8) score among women with BC.

Methods

Data from the Women's Health Initiative were utilized. The primary exposure was the LE8 score assessed prior to BC diagnosis. The LE8 score was stratified into low (0-59), moderate (60-79), and high (80-100) cardiovascular health (CVH). The primary endpoint was a composite of incident CVD events, which included coronary heart disease, defined as myocardial infarction along with coronary revascularization, CVD death, and stroke. We calculated the cumulative incidence of CVD and estimated hazard ratios.

Results

Among 7,165 participants, the median age was 70.1 years at BC diagnosis. The mean LE8 score was 62.0 ± 12.2. Over a median follow-up period of 6 years, 490 composite CVD events occurred. The risk of CVD events was highest for low CVH compared with moderate and high CVH. Compared with low CVH, the hazard ratio for incident CVD was 0.57 (95% CI: 0.46-0.69) for moderate CVH and 0.34 (95% CI: 0.20-0.59) for high CVH. LE8, in conjunction with age, provided a C-statistic of 0.74 for the composite risk of CVD.

Conclusions

Higher LE8 scores were associated with a lower risk of incident CVD among women with BC in the United States.
