Abstract Aims Left ventricular hypertrophy (LVH) has been associated with an increased risk of cardiovascular (CV) disease and linked to increased morbidity and mortality. In patients with chronic kidney disease (CKD) and type 2 diabetes (T2D), hypertension is common, and patients with these co‐morbidities additionally have a high prevalence of LVH. This analysis of the prespecified pooled FIDELITY analysis comprising the randomized, double‐blind, placebo‐controlled, multicentre FIDELIO‐DKD and FIGARO‐DKD phase III studies aimed to explore the CV and kidney effects of finerenone, a nonsteroidal mineralocorticoid receptor antagonist, in patients with CKD and T2D stratified by a diagnosis of LVH at baseline. Methods and results A diagnosis of LVH in the FIDELITY patient population was determined at baseline using investigator‐reported electrocardiogram (ECG) findings. The two efficacy outcomes, assessed by baseline LVH, were the composite CV outcome of time to CV death, non‐fatal myocardial infarction, non‐fatal stroke, or hospitalization for heart failure (HHF), and a composite kidney outcome of time to onset of kidney failure, a sustained decrease in estimated glomerular filtration rate (eGFR) ≥57% from baseline over ≥4 weeks, or kidney‐related death. Safety outcomes by baseline LVH were reported as treatment‐emergent adverse events. At baseline out of 13 026 patients in FIDELITY, 96.5% had hypertension and 9.6% had investigator‐reported LVH. The relative risk reduction for the composite CV and kidney outcomes with finerenone versus placebo was lower in the LVH subgroup; however, the treatment effect of finerenone was not modified by baseline LVH for either outcome (Pinteraction = 0.1075 for composite CV outcome and Pinteraction = 0.1782 for composite kidney outcome). Analysis of the composite CV outcome components showed a greater reduction in the risk of HHF versus placebo for patients with baseline LVH compared with those without (Pinteraction = 0.0024). Overall safety events were comparable between the LVH subgroups and treatment arms. Treatment‐emergent hyperkalaemia was observed more frequently with finerenone versus placebo, but discontinuation rates were low in both treatment arms and between LVH subgroups. Conclusions In conclusion, the overall CV and kidney benefits of finerenone versus placebo were not modified by the presence of LVH at baseline, with overall safety findings being similar between LVH subgroups. A greater benefit was observed for HHF in patients with versus without LVH, suggesting that LVH may be a predictor of the treatment effect of finerenone on HHF.

Abstract Aims In low‐risk patients with severe aortic stenosis (AS), sutureless surgical aortic valve replacement (SU‐SAVR) may be an alternative to transcatheter aortic valve implantation (TAVI). The risk of heart failure hospitalization (HFH) after aortic valve replacement (AVR) in this population is incompletely characterized. This study aims to investigate the incidence, predictors, and outcomes of HFH in patients undergoing SU‐SAVR versus TAVI. Methods and results Patients referred for AVR between 2013 and 2020 at two centres were consecutively included. The decision for SU‐SAVR or TAVI was determined by a multidisciplinary Heart Team. Cox regression and competing risk analysis were conducted to assess adverse events. Of 594 patients (mean age 77.5 ± 6.4, 59.8% male), 424 underwent SU‐SAVR, while 170 underwent TAVI. Following a mean follow‐up of 34.1 ± 23.1 months, HFH occurred in 112 (27.8%) SU‐SAVR patients and in 8 (4.8%) TAVI patients (P

Background Several early-phase clinical trials for the treatment of nonalcoholic steatohepatitis (NASH) use liver fat content as measured with the MRI-derived proton density fat fraction (PDFF) for a primary outcome. These trials have shown relative reductions in liver fat content with placebo treatment alone, a phenomenon termed the placebo effect. This phenomenon confounds the results and limits generalizability to future trials. Purpose To quantify the effect of placebo treatment on change in the absolute PDFF value and to identify variables associated with this observed change. Materials and Methods This is a secondary analysis of prospectively collected data from seven early phase clinical trials that included participants with a diagnosis of NASH based on MRI and/or liver biopsy who received placebo treatment. The primary outcome was a greater than or equal to 30% relative reduction in PDFF after placebo treatment. Normalization of PDFF, relative change in alanine aminotransferase (ALT) level, and normalization of ALT level were also examined. An exploratory linear mixed-effects model was used to estimate an overall change in absolute PDFF and to explore parameters associated with this response. Results A total of 187 participants (median age, 52 years [IQR, 43-60 years]; 114 women) who received placebo treatment were evaluated. A greater than or equal to 30% relative reduction in baseline PDFF was seen in 20% of participants after 12 weeks of placebo treatment (10 of 49), 9% of participants after 16 weeks (two of 22), and 28% of participants after 24 weeks (34 of 122). A repeated-measures linear mixed-effects model estimated a decrease of 2.3 units (median relative reduction of 13%) in absolute PDFF values after 24 weeks of placebo treatment (95% CI: 3.2, 1.4; P < .001). Conclusion In this analysis of 187 participants, a clinically relevant decrease in PDFF was observed with placebo treatment. Based on the study model, assuming an absolute PDFF decrease of approximately 3 units (upper limit of 95% CI) to account for this placebo effect in sample size calculations for future clinical trials is suggested.

Patent foramen ovale (PFO) closure, along with medical therapy, has emerged as the therapeutic gold standard in younger (60 years) patients with a PFO-related cerebrovascular event, a complex group of patients who were mostly excluded from PFO closure clinical trials. Nevertheless, several studies have shown a higher prevalence of PFO among older patients with cryptogenic stroke, and its presence has been associated with an increased risk of recurrent events. Furthermore, older patients exhibit a higher prevalence of high-risk PFO anatomical features, present inherent age-related risk factors that might increase the risk of paradoxical embolism through a PFO, and have a higher incidence of ischemic events after a PFO-related event. Additionally, observational studies have shown the safety and preliminary efficacy of PFO closure in older PFO-related stroke patients. Yet, higher rates of recurrent cerebrovascular events and new-onset atrial fibrillation were observed in some studies among older patients compared to their younger counterparts. After careful case-by-case evaluation, including the assessment of hidden potential cardioembolic sources of a cryptogenic stroke other than PFO, transcatheter PFO closure might be a safe and effective therapeutic option for preventing recurrent thromboembolic events in patients >60 years with a high-risk PFO-associated stroke. Ongoing trials will provide important insights into the role of PFO closure in the elderly population.

Objectives This study aimed to evaluate the efficacy and safety of finerenone, a selective, non-steroidal mineralocorticoid receptor antagonist, on cardiovascular and kidney outcomes by age and/or sex.Design FIDELITY post hoc analysis; median follow-up of 3 years.Setting FIDELITY: a prespecified analysis of the FIDELIO-DKD and FIGARO-DKD trials.Participants Adults with type 2 diabetes and chronic kidney disease receiving optimised renin–angiotensin system inhibitors (N=13 026).Interventions Randomised 1:1; finerenone or placebo.Primary and secondary outcome measures Cardiovascular (cardiovascular death, non-fatal myocardial infarction, non-fatal stroke or hospitalisation for heart failure (HHF)) and kidney (kidney failure, sustained ≥57% estimated glomerular filtration rate (eGFR) decline or renal death) composite outcomes.Results Mean age was 64.8 years; 45.2%, 40.1% and 14.7% were aged

Background and aims: Dyslipidaemia is a significant risk factor for cardiovascular disease in the Mexican population. This analysis aimed to describe the baseline LDL-c levels of patients presenting to cardiovascular clinics and evaluate the proportion who achieved their risk-based LDL-c goals as recommended by 2021 ESC prevention guidelines. Methods: The REMECAR registry is an observational study of patients attending a specialized cardiovascular clinic for their first visit. The cardiovascular risk was retrospectively determined using the 2021 ESC guideline stratification and the SCORE2 and SCORE-OP. Results: A total of 5443 patients were included in the analysis. Within this population, 55.96% presented as very high, 39.98% as high and 4.06% as moderate to low risk. 63% of the participants were not on any lipid-lowering treatment at entry, while 12.4% were receiving high-intensity statin therapy. Patients presenting with established atherosclerotic cardiovascular disease had a mean LDL-c of 90.9 ± 40.7 mg/dL. Of these, 14.1% were achieving LDL-c levels of 70–55 mg/dL and 19.3% were achieving LDL-c levels

Background Scarce data exist on sex differences in patients with cryptogenic cerebrovascular events undergoing patent foramen ovale (PFO) closure. This study aimed to determine the sex differences in clinical profile, procedural characteristics, and long‐term outcomes of patients with cryptogenic cerebrovascular events undergoing PFO closure. Methods and Results A retrospective cohort was used, including 1076 consecutive patients undergoing PFO closure because of a cryptogenic cerebrovascular event. Patients were divided into 2 groups: 469 (43.6%) women and 607 (56.4%) men. The median follow‐up was 3 years (interquartile range, 2–8 years). Women were younger (46±13 versus 50±12 years; P

Therapeutic Area: Kidney Disease Background: Left ventricular hypertrophy (LVH) is a predictor of cardiovascular (CV) disease and associated morbidity and mortality. Patients with chronic kidney disease (CKD), type 2 diabetes (T2D) have a higher prevalence of LVH. In this exploratory analysis we investigated the effect of baseline LVH on cardiovascular and renal outcomes from FIDELITY, a pooled dataset from two phase III multicentre, double-blind trials of patients with CKD and T2D (FIDELIO-DKD and FIGARO-DKD). Methods: Patients in FIDELITY were treated with the maximum tolerated labelled dose of a renin–angiotensin system inhibitor (RASi) and randomized 1:1 to finerenone or placebo. LVH at baseline was determined based on coded electrocardiogram findings. Efficacy outcomes included a composite of CV death, non-fatal myocardial infarction (MI), non-fatal stroke, or hospitalization for heart failure (HFF), and a composite of kidney failure, a sustained ≥57% decrease in estimated glomerular filtration rate from baseline over ≥4 weeks, or renal death. Safety was also assessed. Results: Notable differences in demographics and baseline characteristics included higher systolic blood pressure and urine albumin-to-creatinine ratio in patients with LVH vs those without. Finerenone consistently reduced the relative risk of the CV composite outcome in patients with and without LVH (reduction of 28% vs 11%, respectively; p-value for interaction 0.11; Figure). The relative risk of HHF was reduced in both patient subgroups (66% reduction in patients with LVH vs 14% without LVH), with the effect of finerenone being significantly greater in patients with LVH (p-value for interaction 0.0024). Overall safety was similar between subgroups. The incidence of hyperkalaemia was higher with finerenone vs placebo irrespective of baseline LVH status, however discontinuation due to hyperkalaemia remained low in both groups. Conclusions: In this exploratory analysis, finerenone, in addition to standard of care with a RASi, reduced the overall risk of CV and kidney outcomes in patients with CKD and T2D with or without LVH at baseline. Furthermore, the effect of finerenone in reducing the incidence of HHF appeared to be more pronounced in patients with LVH than in those without.

Transcatheter patent foramen ovale (PFO) closure is a safe and effective treatment for secondary prevention after a PFO-associated stroke as demonstrated in multiple large randomized clinical trials. However, these trials excluded a significant proportion of patients who could have benefited from percutaneous PFO closure due to coexisting potential confounders such as additional thromboembolic risk factors, namely thrombophilia. Since scarce and conflicting data existed on such patients, current clinical management guidelines on patients with PFO mainly recommended against PFO closure in patients with thrombophilia and failed to provide any recommendation on the type and duration of antithrombotic treatment after transcatheter PFO closure. In the past 2 years, there has been new evidence supporting transcatheter PFO closure as a clinically meaningful alternative (vs. medical treatment) in this high-risk group of patients, along with additional data supporting the important role of systematic screening for thrombophilia in PFO-associated cerebrovascular events. This review article provides an updated overview of the incidence, clinical characteristics and outcomes of PFO closure in patients with thrombophilia, also commenting on the most appropriate medical treatment after PFO closure and future perspectives in the field.

Background/Objectives: The recommendations for antithrombotic therapy after transcatheter edge-to-edge mitral valve repair (TEER) are empirical, and the benefit of antiplatelet (APT) or anticoagulation therapy (ACT) remains undetermined. The study sought to investigate the degree and the timing of coagulation and platelet marker activation after TEER. Methods: This was a prospective study including 46 patients undergoing TEER. The markers of coagulation activation, namely prothrombin fragment 1 + 2 (F1 + 2) and thrombin-antithrombin III (TAT), and the markers of platelet activation, namely soluble P-Selectin and soluble CD-40 ligand (sCD40L), were measured at baseline, 24 h, 1 month, and 1 year after TEER. Results: At discharge, 20 (43%) patients received APT (single: 16, dual: 4), 24 (52%) received ACT, and 2 (4%) had both single APT and ACT. Levels of F1 + 2 and TAT significantly increased at 24 h post TEER (both p < 0.001), rapidly returning to baseline levels at 1 month. However, levels of F1 + 2 and TAT remained higher at 1 month in patients without ACT compared to patients with ACT (respectively, 303.1 vs. 148.1 pmol/L; p < 0.001 and 4.6 vs. 3.0 µg/L; p = 0.020), with a similar trend at 1 year. Levels of soluble P-selectin and sCD40L remained stable at all times after TEER (respectively, p = 0.071 and p = 0.056), regardless of the APT. Conclusions: TEER is associated with an acute activation of the coagulation system, with no increase in platelet activation markers. Hence, the use of dual APT is questionable in this population. Our results raise the hypothesis that the optimal antithrombotic therapy after TEER could be short-term ACT over APT. Further larger studies are warranted. [ABSTRACT FROM AUTHOR]

Background/Objectives: Patients with cardiogenic shock on veno-arterial extracorporeal membrane oxygenation (VA-ECMO) frequently develop left ventricular (LV) distension and pulmonary edema due to an increased LV afterload. A balloon atrial septostomy (BAS) is a technique used to alleviate LV pressure and facilitate left atrial decompression. While primarily performed in pediatric populations, this procedure's feasibility in adult patients is less studied. This study aimed to evaluate the procedural outcomes, including the safety and effectiveness, of BASs in adult patients with cardiogenic shock supported by VA-ECMO. Methods: This single-center retrospective study included 11 adult patients with cardiogenic shock on VA-ECMO, who underwent a BAS between 2012 and 2023. Multiple parameters were used to evaluate the global clinical impact of a BAS on patients with cardiogenic shock. Results: Between 2012 and 2023, 11 patients with cardiogenic shock on VA-ECMO underwent a BAS procedure in our institution. The mean time from the BAS to advanced therapy was 6.4 days. Procedural success was achieved in all patients with no complications. Nine patients (82%) had an improvement in PaO2/FiO2 24 h post-BAS procedure. All patients had an improvement in the pulmonary edema on the chest X-ray 24 to 48 h after the procedure, with clear radiography achieved in nine patients (82%) in a mean time of 7 days (range: 1.5–13 days). A total of five patients (45%) had in-hospital mortality due to non-procedural complications and the mortality timing from BAS was between 5 to 23 days. Among those discharged, all six patients were alive at the 1-year follow-up. Conclusions: A BAS is a feasible and safe technique for decompressing the left atrium in adult patients on VA-ECMO. It significantly improved pulmonary edema and oxygenation in most cases. Further studies with larger populations are needed to evaluate its impact on long-term outcomes. [ABSTRACT FROM AUTHOR]

La presente propuesta tiene como objetivo principal, a partir de la interpretación de la historia de la humanidad como historia de la fabricación, realizar un recorrido crítico del pensamiento de Vilém Flusser con especial énfasis en cómo define y caracteriza el paso de la relación hombre-máquina al binomio hombre-aparato en las sociedades contemporáneas signadas por las imágenes técnicas.

El presente artículo tiene como objetivo central caracterizar y discutir ciertas problemáticas que encierran los dispositivos electrónicos de votación desde una mirada sociológica y filosófica de la tecnología que sea capaz de tensionar algunos de los presupuestos y prenociones que subyacen a los intentos de modernizar los sistemas tradicionales de voto. En un contexto signado por la fascinación por las nuevas tecnologías, distintas voces se encargan de subrayar las presuntas ventajas de la votación electrónica como solución ante las dificultades que enfrenta la votación tradicional. Así, frente a las promesas y expectativas que envuelven a las narrativas tecnofílicas en torno a su implementación, también se busca poner en discusión ese cariz tecnooptimista que impregna a los discursos públicos a la luz de diferentes estudios que conciben al dispositivo del voto electrónico como una caja negra, al inhabilitar el control y auditoría del voto por parte de la ciudadanía. Por consiguiente, en tanto sistema opaco y cerrado, estos dispositivos aparecen como un fiel representante de la alienación tecnológica.

Abstract Background Direct oral anticoagulants (DOACs) provide a safe, effective alternative to vitamin K antagonists (VKAs) for venous thromboembolism (VTE) treatment, as shown via intention-to-treat comparative effectiveness analysis. However, on-treatment analysis is imperative in observational studies because anticoagulation choice and duration are at investigators' discretion. Objectives The aim of the study is to compare the effectiveness of DOACs and VKAs on 12-month outcomes in VTE patients using on-treatment analysis. Methods The Global Anticoagulant Registry in the FIELD - VTE (GARFIELD-VTE) is a world-wide, prospective, non-interventional study observing treatment of VTE in routine clinical practice. Results In total, 8,034 patients received VKAs (n = 3,043, 37.9%) or DOACs (n = 4,991, 62.1%). After adjustment for baseline characteristics and follow-up bleeding events, and accounting for possible time-varying confounding, all-cause mortality was significantly lower with DOACs than VKAs (hazard ratio: 0.58 [95% confidence interval 0.42–0.79]). Furthermore, patients receiving VKAs were more likely to die of VTE complications (4.9 vs. 2.2%) or bleeding (4.9 vs. 0.0%). There was no significant difference in rates of recurrent VTE (hazard ratio: 0.74 [0.55–1.01]), major bleeding (hazard ratio: 0.76 [0.47–1.24]), or overall bleeding (hazard ratio: 0.87 [0.72–1.05]) with DOACs or VKAs. Unadjusted analyses suggested that VKA patients with active cancer or renal insufficiency were more likely to die than patients treated with DOAC (52.51 [37.33–73.86] vs. 26.52 [19.37–36.29] and 9.97 [7.51–13.23] vs. 4.70 [3.25–6.81] per 100 person-years, respectively). Conclusion DOACs and VKAs had similar rates of recurrent VTE and major bleeding. However, DOACs were associated with reduced all-cause mortality and a lower likelihood of death from VTE or bleeding compared with VKAs.

Aims: In low‐risk patients with severe aortic stenosis (AS), sutureless surgical aortic valve replacement (SU‐SAVR) may be an alternative to transcatheter aortic valve implantation (TAVI). The risk of heart failure hospitalization (HFH) after aortic valve replacement (AVR) in this population is incompletely characterized. This study aims to investigate the incidence, predictors, and outcomes of HFH in patients undergoing SU‐SAVR versus TAVI. Methods and results: Patients referred for AVR between 2013 and 2020 at two centres were consecutively included. The decision for SU‐SAVR or TAVI was determined by a multidisciplinary Heart Team. Cox regression and competing risk analysis were conducted to assess adverse events. Of 594 patients (mean age 77.5 ± 6.4, 59.8% male), 424 underwent SU‐SAVR, while 170 underwent TAVI. Following a mean follow‐up of 34.1 ± 23.1 months, HFH occurred in 112 (27.8%) SU‐SAVR patients and in 8 (4.8%) TAVI patients (P < 0.001). The SU‐SAVR cohort exhibited higher all‐cause mortality (138 [32.5%] patients compared with 30 [17.6%] in the TAVI cohort [P < 0.001]). These differences remained significant after sensitivity analyses with 1:1 propensity score matching for baseline variables. SU‐SAVR with HFH was associated with increased all‐cause mortality (61.6% vs. 23.1%, P < 0.001). Independent associates of HFH in SU‐SAVR patients included diabetes, atrial fibrillation, chronic obstructive pulmonary disease, lower glomerular filtration rate and lower left ventricular ejection fraction. SU‐SAVR patients with HFH had a 12‐month LVEF of 59.4 ± 12.7. Conclusions: In low‐risk AS, SU‐SAVR is associated with a higher risk of HFH and all‐cause mortality compared to TAVI. In patients with severe AS candidate to SU‐SAVR or TAVI, TAVI may be the preferred intervention. [ABSTRACT FROM AUTHOR]

Background: In the phase 3 clinical trials FIGARO-DKD and FIDELIO-DKD, finerenone reduced the risk of cardiovascular and kidney events among people with chronic kidney disease (CKD) and type 2 diabetes (T2D). Evidence regarding finerenone use in real-world settings is limited. Methods: A retrospective cohort study (NCT06278207) using two Japanese nationwide hospital-based databases provided by Medical Data Vision (MDV) and Real World Data Co., Ltd. (RWD Co., Kyoto Japan), converted to the OMOP common data model, was conducted. Persons with CKD and T2D initiating finerenone from 1 July 2021, to 30 August 2023, were included. Baseline characteristics were described. The occurrence of hyperkalemia after finerenone initiation was assessed. Results: 1029 new users of finerenone were included (967 from MDV and 62 from RWD Co.). Mean age was 69.5 and 72.4 years with 27.3% and 27.4% being female in the MDV and RWD Co. databases, respectively. Hypertension (92 and 95%), hyperlipidemia (59 and 71%), and congestive heart failure (60 and 66%) were commonly observed comorbidities. At baseline, 80% of persons were prescribed angiotensin-converting-enzyme inhibitors or angiotensin-receptor blockers. Sodium–glucose cotransporter 2 inhibitors and glucagon-like peptide 1 receptor agonists were prescribed in 72% and 30% of the study population, respectively. The incidence proportions of hyperkalemia were 2.16 and 2.70 per 100 persons in the MDV and RWD Co. databases, respectively. There were no hospitalizations associated with hyperkalemia observed in either of the two datasets. Conclusions: For the first time, we report the largest current evidence on the clinical use of finerenone in real-world settings early after the drug authorization in Japan. This early evidence from clinical practice suggests that finerenone is used across comorbidities and comedications. [ABSTRACT FROM AUTHOR]

El presente artículo tiene como objetivo central explorar y analizar el ascenso y caída del automóvil Tucker 48 desde un enfoque sociotécnico en el marco del pleno desarrollo de las sociedades industriales avanzadas, en las cuales el automóvil goza de prerrogativa en tanto que se configura y erige como emblema y representante del triunfo de la subjetividad moderna. Tomando en consideración la marginalidad de estudios historiográficos abocados al tratamiento de innovaciones y “fracasos” tecnológicos, la propuesta pretende destacar la importancia de los desarrollos de Preston Tucker en el posterior andamiaje y funcionamiento del automóvil. Frente a nociones deterministas e instrumentalistas que pregonan la autonomía, neutralidad e independencia de la tecnología respecto a la sociedad, el abordaje del Tucker 48 demanda una mirada multidireccional y sistémica a fin de ilustrar de forma cabal la complejidad inherente a su comportamiento y funcionamiento. El análisis desde la perspectiva sociotécnica permite identificar algunos de los vínculos fundamentales entre el poder tecnológico y el poder económico que influyen en los procesos de cambio dentro del capitalismo.
