Renin–angiotensin–aldosterone system blockers effect in chronic kidney disease progression in hypertensive elderly patients without proteinuria: PROERCAN trial / Efecto de los bloqueantes del sistema renina-angiotensina-aldosterona en la progresión de enfermedad renal crónica en pacientes hipertensos añosos sin proteinuria: ensayo clínico Progresión de Enfermedad Renal Crónica en Ancianos

Introduction: Evidence about nefroprotective effect with RAAS blockers in elderly patients with chronic kidney disease (CKD) without proteinuria is lacking. The primary outcome of our study is to evaluate the impact of RAAS blockers in CKD progression in elderly patients without proteinuria. Materials and methods: Multicenter open-label, randomized controlled clinical trial including patients over 65 year-old with hypertension and CKD stages 3–4 without proteinuria. Patients were randomized in a 1:1 ratio to either receive RAAS blockers or other antihypertensive drugs and were followed up for three years. Primary outcome is estimated glomerular filtration rate (eGFR) decline at 3 years. Secondary outcome measures include BP control, renal and cardiovascular events and mortality. Results: 88 patients were included with a mean age of 77.9±6.1 years and a follow up period of 3 years: 40 were randomized to RAAS group and 48 to standard treatment. Ethiology of CKD was: 53 vascular, 16 interstitial and 19 of unknown ethiology. In the RAAS group eGFR slope during follow up was −4.3±1.1ml/min, whereas in the standard treatment group an increase on eGFR was observed after 3 years (+4.6±0.4ml/min), p=0.024. We found no differences in blood pressure control, number of antihypertensive drugs, albuminuria, potassium serum levels, incidence of cardiovascular events nor mortality during the follow up period. Conclusions: In elderly patients without diabetes nor cardiopathy and with non proteinuric CKD the use of RAAS blockers does not show a reduction in CKD progression.

Introducción: Actualmente no existe suficiente evidencia sobre el efecto nefroprotector de los bloqueantes del sistema renina-angiotensina-aldosterona (BSRAA) en pacientes añosos con enfermedad renal crónica (ERC) sin proteinuria y sin cardiopatía. El objetivo es evaluar el efecto de los BSRAA en la progresión de la ERC en este grupo poblacional. Métodos: Se trata de un estudio prospectivo, aleatorizado, que compara la eficacia de los BSRAA vs. otros tratamientos antihipertensivos en la progresión renal en personas mayores de 65 años con ERC estadios 3 y 4 e índice albúmina/creatinina<30mg/g. Aleatorización 1:1 BSRAA o tratamiento antihipertensivo estándar. Se recogieron cifras tensionales y parámetros analíticos de un año previo a la aleatorización y durante el seguimiento. Resultados: Se incluyeron 88 pacientes seguidos durante tres años con edad media de 77,9±6,1 años. De estos, se aleatorizaron 40 al grupo BSRAA y 48 al estándar. La etiología de ERC fue: 53 vascular, 16 intersticial y 19 no filiada. En el primer grupo se observó una progresión de la ERC con una caída del filtrado glomerular estimado (FGe) de -4,3±1,1mL/min, mientras que en el grupo estándar un aumento del FGe durante el seguimiento de 4,6±0,4mL/min, p=0,024. No se apreciaron diferencias entre ambos en el control tensional, el número de antihipertensivos, la albuminuria, los niveles de potasio, la incidencia de eventos cardiovasculares ni la mortalidad durante el seguimiento. Conclusiones: En pacientes añosos no diabéticos con ERC no proteinúrica y sin cardiopatía el uso de BSRAA no añade beneficio en la progresión de la ERC.

Factors Associated with Neonatal Arterial Hypertension: Case and Control Study.

Background. Neonatal high blood pressure has been diagnosed more frequently in recent years, and its impact extends to adulthood. However, the knowledge gaps on associated factors, diagnosis, and treatment are challenging for medical personnel. The incidence of this condition varies depending on neonatal conditions. Patients in the Newborn Unit are at increased risk of developing high blood pressure. The persistence of this condition beyond the neonatal stage increases the risk of cardiovascular disease and chronic kidney disease in childhood and adulthood. Methodology. A case-control study was carried out. It included hospitalized patients with neonatal hypertension as cases. Three controls were randomly selected for each case and matched by gestational age. The variables were analyzed based on their nature. Multivariate analysis was performed using a multivariate conditional regression model to identify variables associated with the outcome. Finally, the model was adjusted for possible confounders. Results. 37 cases were obtained and matched with 111 controls. In the univariate analysis, heart disease (OR 2.86; 95% CI 1.22-6.71), kidney disease (OR 7.24; 95% CI 1.92-28.28), bronchopulmonary dysplasia (OR 6.62; 95% CI 1.42-50.82) and major surgical procedures (OR 3.71; 95% CI 1.64-8.39) had an association with neonatal arterial hypertension. Only the latter maintained this finding in the multivariate analysis (adjusted OR 2.88; 95% CI 1.14-7.30). A significant association of two or more comorbidities with neonatal arterial hypertension was also found (OR 3.81; 95% CI 1.53-9.49). Conclusions. The study analyzed the factors related to high blood pressure in hospitalized neonates, finding relevant associations in the said population. The importance of meticulous neonatal care and monitoring of risk factors such as birth weight and major surgeries is highlighted.

Recurrent intra-cardiac thrombosis: A rare manifestation of Behçet's disease.

Behçet's disease is a systemic vasculitis characterized by recurrent bipolar aphtosis and ophthalmic disorders. Cardiac involvement is rarely reported and could be associated to poor prognosis. Intracardiac thrombosis is exceptional and represents a therapeutic issue. We report the case of a young man admitted in internal medicine department for management of prolonged fever and recurrent mouth ulcers.

The value of cardiopulmonary comorbidity in patients with acute large vessel occlusion stroke undergoing endovascular thrombectomy: a retrospective, observational cohort study.

BACKGROUND: Chronic lung and heart diseases are more likely to lead an intensive end point after stroke onset. We aimed to investigate characteristics and outcomes of endovascular thrombectomy (EVT) in patients with acute large vessel occlusion stroke (ALVOS) and identify the role of comorbid chronic cardiopulmonary diseases in ALVOS pathogenesis. METHODS: In this single-center retrospective study, 191 consecutive patients who underwent EVT due to large vessel occlusion stroke in neurological intensive care unit were included. The chronic cardiopulmonary comorbidities and several conventional stroke risk factors were assessed. The primary efficacy outcome was functional independence (defined as a mRS of 0 to 2) at day 90. The primary safety outcomes were death within 90 days and the occurrence of symptomatic intracranial hemorrhage(sICH). Univariate analysis was applied to evaluate the relationship between factors and clinical outcomes, and logistic regression model were developed to predict the prognosis of ALVOS. RESULTS: Endovascular therapy in ALVOS patients with chronic cardiopulmonary diseases, as compared with those without comorbidity, was associated with an unfavorable shift in the NHISS 24 h after EVT [8(4,15.25) versus 12(7.5,18.5), P = 0.005] and the lower percentage of patients who were functionally independent at 90 days, defined as a score on the modified Rankin scale of 0 to 2 (51.6% versus 25.4%, P = 0.000). There was no significant between-group difference in the frequency of mortality (12.1% versus 14.9%, P = 0.580) and symptomatic intracranial hemorrhage (13.7% versus 19.4%, P = 0.302) or of serious adverse events. Moreover, a prediction model showed that existence of cardiopulmonary comorbidities (OR = 0.456, 95%CI 0.209 to 0.992, P = 0.048) was independently associated with functional independence at day 90. CONCLUSIONS: EVT was safe in ALVOS patients with chronic cardiopulmonary diseases, whereas the unfavorable outcomes were achieved in such patients. Moreover, cardiopulmonary comorbidity had certain clinical predictive value for worse stroke prognosis.

[A Thrombus in the Right Atrium Associated with Pyogenic Liver Abscess].

Hepatic abscesses are divided into bacterial and amoebic types. Although the prognosis of bacterial liver abscesses has improved owing to progress in drainage techniques and antimicrobial agents, poor outcomes remain common. While there have been some reports of amoebic liver abscesses complicated by thrombosis, bacterial liver abscesses and subsequent thrombus in the right atrium are very rare. We herein report the case of an 82-year-old man. He had suffered acute obstructive suppurative cholangitis 10 months previously, and bile culture yielded Enterococcus faecalis. In the present case, a right atrial thrombus caused by a bacterial liver abscess was observed and the causative organism was thought to be Enterococcus faecalis, for which was detected in a blood culture was positive. The patient was successfully treated with hepatic abscess drainage and surgical right atrial thrombectomy under cardiopulmonary bypass with a beating heart.

Genetic markers of cardiac autonomic neuropathy in the Kazakh population.

BACKGROUND: Cardiac autonomic neuropathy (CAN) is a complication of diabetes mellitus (DM) that increases the risk of morbidity and mortality by disrupting cardiac innervation. Recent evidence suggests that CAN may manifest even before the onset of DM, with prediabetes and metabolic syndrome potentially serving as precursors. This study aims to identify genetic markers associated with CAN development in the Kazakh population by investigating the SNPs of specific genes. MATERIALS AND METHODS: A case-control study involved 82 patients with CAN (cases) and 100 patients without CAN (controls). A total of 182 individuals of Kazakh nationality were enrolled from a hospital affiliated with the RSE "Medical Center Hospital of the President's Affairs Administration of the Republic of Kazakhstan". 7 SNPs of genes FTO, PPARG, SNCA, XRCC1, FLACC1/CASP8 were studied. Statistical analysis was performed using Chi-square methods, calculation of odds ratios (OR) with 95% confidence intervals (CI), and logistic regression in SPSS 26.0. RESULTS: Among the SNCA gene polymorphisms, rs2737029 was significantly associated with CAN, almost doubling the risk of CAN (OR 2.03(1.09-3.77), p = 0.03). However, no statistically significant association with CAN was detected with the rs2736990 of the SNCA gene (OR 1.00 CI (0.63-1.59), p = 0.99). rs12149832 of the FTO gene increased the risk of CAN threefold (OR 3.22(1.04-9.95), p = 0.04), while rs1801282 of the PPARG gene and rs13016963 of the FLACC1 gene increased the risk twofold (OR 2.56(1.19-5.49), p = 0.02) and (OR 2.34(1.00-5.46), p = 0.05) respectively. rs1108775 and rs1799782 of the XRCC1 gene were associated with reduced chances of developing CAN both before and after adjustment (OR 0.24, CI (0.09-0.68), p = 0.007, and OR 0.43, CI (0.22-0.84), p = 0.02, respectively). CONCLUSION: The study suggests that rs2737029 (SNCA gene), rs12149832 (FTO gene), rs1801282 (PPARG gene), and rs13016963 (FLACC1 gene) may be predisposing factors for CAN development. Additionally, SNPs rs1108775 and rs1799782 (XRCC1 gene) may confer resistance to CAN. Only one polymorphism rs2736990 of the SNCA gene was not associated with CAN.

Betaine Protects Mice from Cardiotoxicity Triggered by Sodium Arsenite Through Antioxidative and Anti-inflammatory Pathways.

NaAsO2 is known as a harmful pollutant all over the world, and many chronic heart diseases can be attributed to its prolonged exposure in NaAsO2-contaminated water. Therefore, considering the anti-inflammatory and antioxidant effects of betaine (BET), in this study, our team investigated the cardioprotective effects of this phytochemical agent on sodium arsenite (NaAsO2)-induced cardiotoxicity. Forty male mice were randomly divided into 4 groups: (I) Control; (II) BET (500 mg/kg); (III) NaAsO2 (50 ppm); and (IV) NaAsO2 + BET. NaAsO2 was given to the animals for 8 weeks, but BET was given in the last two weeks. After decapitation, inflammatory factors and biochemical parameters were measured, and Western blot analyses were performed. BET decrease the activity level of alanine aspartate aminotransferase, creatine kinase MB, thiobarbituric acid reactive substances level, inflammatory factors (tumor necrosis factor-α) content, and nuclear factor kappa B expression. Furthermore, BET increased cardiac total thiol and activity levels of catalase, superoxide dismutase, and glutathione peroxidase and nuclear factor erythroid-2 expression. Hence, the administration of BET ameliorated the deleterious effects stemming from the imbalance of oxidative and antioxidant pathways and histopathological alterations observed in NaAsO2-intoxicated mice, thereby attenuating oxidative stress-induced damage and inflammation.

CardioHotspots: a database of mutational hotspots for cardiac disorders.

Mutational hotspots are DNA regions with an abnormally high frequency of genetic variants. Identifying whether a variant is located in a mutational hotspot is critical for determining the variant's role in disorder predisposition, development, and treatment response. Despite their significance, current databases on mutational hotspots are limited to the oncology domain. However, identifying mutational hotspots is critical for any disorder in which genetics plays a role. This is true for the world's leading cause of death: cardiac disorders. In this work, we present CardioHotspots, a literature-based database of manually curated hotspots for cardiac diseases. This is the only database we know of that provides high-quality and easily accessible information about hotspots associated with cardiac disorders. CardioHotspots is publicly accessible via a web-based platform (https://genomics-hub.pros.dsic.upv.es:3099/). Database URL: https://genomics-hub.pros.dsic.upv.es:3099/.

Herpes virus entry mediator signaling blockade produces mortality in neonatal sepsis through induced cardiac dysfunction.

Introduction: Sepsis remains a major source of morbidity and mortality in neonates, and characterization of immune regulation in the neonatal septic response remains limited. HVEM is a checkpoint regulator which can both stimulate or inhibit immune responses and demonstrates altered expression after sepsis. We hypothesized that signaling via HVEM would be essential for the neonatal response to sepsis, and that therefore blockade of this pathway would improve survival to septic challenge. Methods: To explore this, neonatal mice were treated with cecal slurry (CS), CS with Anti-HVEM antibody (CS-Ab) or CS with isotype (CS-IT) and followed for 7-day survival. Mice from all treatment groups had thymus, lung, kidney and peritoneal fluid harvested, weighed, and stained for histologic evaluation, and changes in cardiac function were assessed with echocardiography. Results: Mortality was significantly higher for CS-Ab mice (72.2%) than for CS-IT mice (22.2%). CS resulted in dysregulated alveolar remodeling, but CS-Ab lungs demonstrated significantly less dysfunctional alveolar remodeling than CS alone (MCL 121.0 CS vs. 87.6 CS-Ab), as well as increased renal tubular vacuolization. No morphologic differences in alveolar septation or thymic karyorrhexis were found between CS-Ab and CS-IT. CS-Ab pups exhibited a marked decrease in heart rate (390.3 Sh vs. 342.1 CS-Ab), stroke volume (13.08 CS-IT vs. 8.83 CS-Ab) and ultimately cardiac output (4.90 Sh vs. 3.02 CS-Ab) as well as a significant increase in ejection fraction (73.74 Sh vs. 83.75 CS-Ab) and cardiac strain (40.74 Sh vs. 51.16 CS-Ab) as compared to CS-IT or Sham animals. Discussion: While receptor ligation of aspects of HVEM signaling, via antibody blockade, appears to mitigate aspects of lung injury and thymic involution, stimulatory signaling via HVEM still seems to be necessary for vascular and hemodynamic resilience and overall neonatal mouse survival in response to this experimental polymicrobial septic insult. This dissonance in the activity of anti-HVEM neutralizing antibody in neonatal animals speaks to the differences in how septic cardiac dysfunction should be considered and approached in the neonatal population.

Visualising and quantifying the usefulness of new predictors stratified by outcome class: The U-smile method.

Binary classification methods encompass various algorithms to categorize data points into two distinct classes. Binary prediction, in contrast, estimates the likelihood of a binary event occurring. We introduce a novel graphical and quantitative approach, the U-smile method, for assessing prediction improvement stratified by binary outcome class. The U-smile method utilizes a smile-like plot and novel coefficients to measure the relative and absolute change in prediction compared with the reference method. The likelihood-ratio test was used to assess the significance of the change in prediction. Logistic regression models using the Heart Disease dataset and generated random variables were employed to validate the U-smile method. The receiver operating characteristic (ROC) curve was used to compare the results of the U-smile method. The likelihood-ratio test demonstrated that the proposed coefficients consistently generated smile-shaped U-smile plots for the most informative predictors. The U-smile plot proved more effective than the ROC curve in comparing the effects of adding new predictors to the reference method. It effectively highlighted differences in model performance for both non-events and events. Visual analysis of the U-smile plots provided an immediate impression of the usefulness of different predictors at a glance. The U-smile method can guide the selection of the most valuable predictors. It can also be helpful in applications beyond prediction.

[Prevention of radiotherapy-related cardiotoxicity : benefits of a specialized cardio-oncologic assessment and follow-up]. / Prévention de la cardio-toxicité de la radiothérapie : apport de la prise en charge cardio-oncologique.

To accept the toxic side effects of any treatment, whether medical, surgical or radiotherapeutic, cannot be avoided but implies to evaluate them taking into account the severity and prognosis of the disease that is concerned. Screening, preventing and treatment of these side effects are an integral aspect of the treatment of cancers. We will here review the contribution of the cardio-oncology, a recently emerged medical specialty. Cardiac irradiation cannot be avoided when treating several cancers, most frequently left sided breast cancer. As soon as radiotherapy is considered, it is of prime importance to evaluate each patient's risk factors and to handle them. If technical progresses have led to the complete disappearance of acute side effects of radiotherapy, this is not true for the delayed ones that may occur many years after the irradiation. Hence the need for «red flags¼ and for a systematic follow-up. Cardiac complications of left breast irradiation concern all aspects of cardiology: diseases of cardiac rhythm, valvulopathies, heart failure, coronary and pericardial disorders.

Admettre les effets secondaires d'un traitement, qu'il soit médical, chirurgical ou radiothérapique, est inévitable, mais impose de les évaluer en intégrant la gravité de l'affection pour laquelle ils sont prescrits. Leur dépistage, leur prévention et leur prise en charge font partie intégrante du traitement d'un cancer. Dans cette revue, nous ferons la synthèse de l'apport à cette démarche d'une discipline récente, la cardio-oncologie. L'irradiation cardiaque est incontournable lors du traitement de plusieurs cancers au premier rang desquels le cancer du sein gauche. Dès qu'elle est envisagée, il est essentiel d'évaluer les facteurs de risque de chaque patient et d'organiser leur prise en charge éventuelle. En effet, si les progrès techniques ont permis la disparition des complications cardiaques aiguës de la radiothérapie, ce n'est encore pas le cas des complications différées qui peuvent survenir de nombreuses années après l'irradiation. D'où la nécessité de «drapeaux rouges¼ et d'un suivi régulier systématique. Ces complications, rarement isolées, concernent tous les aspects de la cardiologie : troubles du rythme, valvulopathies, insuffisance cardiaque, maladies coronaires et atteintes péricardiques.

[Cardiac CT in 2024]. / CT cardiaque en 2024.

Coronary Computed Tomography Angiography (CCTA) has now become an established tool in the diagnostic process for patients suspected of coronary artery disease. In light of rapid technological development, CCTA has evolved into an imaging modality providing both anatomical and functional information to guide patient management. In this article, we describe the role of cardiac CT in assessing atherosclerotic plaque, chest pain evaluation, cardiovascular risk stratification, planning and guiding coronary intervention, as well as structural heart diseases.

Le scanner coronarien est actuellement un outil reconnu dans le processus diagnostique des patients chez qui on suspecte une maladie coronarienne. Bénéficiant d'un développement technologique rapide et procurant des informations tant morphologiques que fonctionnelles, le CT cardiaque devient une modalité d'imagerie incontournable pour orienter la prise en charge des patients. Dans cet article, nous décrivons le rôle du CT cardiaque dans l'évaluation de la plaque d'athérosclérose, des douleurs thoraciques, de la stratification du risque cardiovasculaire, de la planification et du guidage de l'intervention coronarienne, ainsi que des maladies cardiaques structurelles.

Cardiac and Renal Comorbidities in Aging People Living With HIV.

Contemporary World Health Organization data indicates that ≈39 million people are living with the human immunodeficiency virus. Of these, 24 million have been reported to have successfully accessed combination antiretroviral therapy. In 1996, the World Health Organization endorsed the widespread use of combination antiretroviral therapy, transforming human immunodeficiency virus infection from being a life-threatening disease to a chronic illness characterized by multiple comorbidities. The increased access to combination antiretroviral therapy has translated to people living with human immunodeficiency virus (PLWH) no longer having a reduced life expectancy. Although aging as a biological process increases exposure to oxidative stress and subsequent systemic inflammation, this effect is likely enhanced in PLWH as they age. This narrative review engages the intricate interplay between human immunodeficiency virus associated chronic inflammation, combination antiretroviral therapy, and cardiac and renal comorbidities development in aging PLWH. We examine the evolving demographic profile of PLWH, emphasizing the increasing prevalence of aging individuals within this population. A central focus of the review discusses the pathophysiological mechanisms that underpin the heightened susceptibility of PLWH to renal and cardiac diseases as they age.

Wnt signaling in cardiac development and heart diseases.

The Wnt signaling pathway is a fundamental cellular communication system with extensive implications in various organs including the heart. In cardiac homeostasis, it governs essential processes like cellular proliferation, differentiation, and apoptosis, ensuring the heart's structural and functional integrity from embryonic stages and throughout life. Both canonical and non-canonical Wnt signaling pathways play a critical role during embryonic heart development in a region- and stage-specific manner. Canonical Wnt signaling also plays a significant role in heart diseases such as myocardial infarction and heart failure. However, the role of non-canonical Wnt signaling in heart diseases has not been fully elucidated. Wnt5a is a major ligand that activates non-canonical Wnt pathway, and recent studies start to clarify the role of the Wnt5a signaling axis in cardiac health and disease. In this review, we will briefly summarize the previous findings on the role of Wnt signaling pathways in heart development and diseases, and then focus on the role of Wnt5a signaling in heart failure progression. The multifaceted roles of the Wnt signaling pathway highlight its therapeutic potential for various types of heart diseases.

The impact of massage and dry cupping on dysrhythmia in cardiac patients: A randomized parallel controlled trial.

BACKGROUND: Heart disease is the leading cause of death in many countries around the world and is linked to numerous complications. In addition to conventional pharmacological treatments, complementary and alternative medicines like massage and dry cupping are employed to help manage the disease and its symptoms. This study aimed to compare the effects of massage and dry cupping on dysrhythmia in patients with heart diseases. METHODS: This randomized parallel controlled clinical trial study was conducted in two critical care units of Shafa hospital in Kerman, southeastern Iran, in 2019-2020. A total of 90 eligible patients were allocated into three groups: massage (n = 30), dry cupping (n = 30), and control (n = 30) using a stratified block randomization method. In the massage group, the head and face were massaged for three consecutive nights, while the dry cupping group received dry cupping between the fifth cervical vertebra and the second thoracic vertebra for the same duration. Each intervention session lasted 15 min. Data collection tools included a socio-demographic and clinical characteristics questionnaire, a form for hemodynamic parameters (systolic blood pressure, diastolic blood pressure, heart rate, respiratory rate, and peripheral oxygen saturation), and a form for assessing dysrhythmia using electrocardiogram readings. Dysrhythmia in the participants was evaluated after each session. RESULTS: The results within each group indicated a statistically significant difference in the prevalence of dysrhythmia in the dry cupping group after the intervention (P < 0.05), but this difference was not statistically significant in the massage and control groups. However, when comparing between the groups, no significant difference was found among the three groups. Additionally, there was no significant difference in the type of dysrhythmia between the groups (P > 0.05). CONCLUSION: While there was no difference in the type of dysrhythmia between the three groups, the additional reduction of dysrhythmia in the dry cupping group could hold clinical significance. Further studies are recommended to validate or refute the findings of the present study.

Risk of Heart Disease in Patients With Amputation: A Nationwide Cohort Study in South Korea.

BACKGROUND: Amputation confers disabilities upon patients and is linked to substantial morbidity and death attributed to heart disease. While some studies have focused on traumatic amputees in veterans, few studies have focused on traumatic amputees within the general population. Therefore, the present study aimed to assess the risk of heart disease in patients with traumatic amputation with disability within the general population using a large-scale nationwide population-based cohort. METHODS AND RESULTS: We used data from the Korean National Health Insurance System. A total of 22 950 participants with amputation were selected with 1:3 age, sex-matched controls between 2010 and 2018. We used Cox proportional hazard models to calculate the risk of myocardial infarction, heart failure, and atrial fibrillation among amputees. Participants with amputation had a higher risk of myocardial infarction (adjusted hazard ratio [aHR], 1.30 [95% CI, 1.14-1.47]), heart failure (aHR, 1.27 [95% CI, 1.17-1.38]), and atrial fibrillation (aHR, 1.17 [95% CI, 1.03-1.33]). The risks of myocardial infarction and heart failure were further increased by the presence of disability (aHR, 1.43 [95% CI, 1.04-1.95]; and aHR, 1.38 [95% CI, 1.13-1.67], respectively). CONCLUSIONS: We demonstrate an increased risk of myocardial infarction, heart failure, and atrial fibrillation among individuals with amputation, and the risk further increased in those with disabilities. Clinicians should pay attention to the increased risk for heart disease in patients with amputation.

Trends of hypertensive heart disease prevalence and mortality in the United States between the period 1990-2019, Global burden of disease database.

Hypertension presents a substantial cardiovascular risk, with poorly managed cases increasing the likelihood of hypertensive heart disease (HHD). This study examines individual-level trends and burdens of HHD in the US from 1990 to 2019, using the Global Burden of Disease (GBD) 2019 database. In 2019, HHD prevalence in the US reached 1,487,975 cases, with stable changes observed since 1990. Sex stratification reveals a notable increase in prevalence among females (AAPC 0.3, 95 % CI: 0.2 to 0.4), while males showed relative constancy (AAPC 0.0, 95 % CI: -0.1 to 0.1). Mortality rates totaled 51,253 cases in 2019, significantly higher than in 1990, particularly among males (AAPC 1.0, 95 % CI: 0.8 to 1.3). Younger adults experienced a surge in HHD-related mortality compared to older adults (AAPC 2.6 versus 2.0). These findings highlight the need for tailored healthcare strategies to address sex and age-specific disparities in managing HHD.

A dynamic probabilistic model of the onset and interaction of cardio-metabolic comorbidities on an ageing adult population.

Comorbidity is widespread in the ageing population, implying multiple and complex medical needs for individuals and a public health burden. Determining risk factors and predicting comorbidity development can help identify at-risk subjects and design prevention strategies. Using socio-demographic and clinical data from approximately 11,000 subjects monitored over 11 years in the English Longitudinal Study of Ageing, we develop a dynamic Bayesian network (DBN) to model the onset and interaction of three cardio-metabolic comorbidities, namely type 2 diabetes (T2D), hypertension, and heart problems. The DBN allows us to identify risk factors for developing each morbidity, simulate ageing progression over time, and stratify the population based on the risk of outcome occurrence. By applying hierarchical agglomerative clustering to the simulated, dynamic risk of experiencing morbidities, we identified patients with similar risk patterns and the variables contributing to their discrimination. The network reveals a direct joint effect of biomarkers and lifestyle on outcomes over time, such as the impact of fasting glucose, HbA1c, and BMI on T2D development. Mediated cross-relationships between comorbidities also emerge, showcasing the interconnected nature of these health issues. The model presents good calibration and discrimination ability, particularly in predicting the onset of T2D (iAUC-ROC = 0.828, iAUC-PR = 0.294) and survival (iAUC-ROC = 0.827, iAUC-PR = 0.311). Stratification analysis unveils two distinct clusters for all comorbidities, effectively discriminated by variables like HbA1c for T2D and age at baseline for heart problems. The developed DBN constitutes an effective, highly-explainable predictive risk tool for simulating and stratifying the dynamic risk of developing cardio-metabolic comorbidities. Its use could help identify the effects of risk factors and develop health policies that prevent the occurrence of comorbidities.
