Background/Objectives: Real-world evidence shows alarmingly suboptimal utilization of guideline directed medical therapy (GDMT) in heart failure with reduced ejection fraction (HFrEF). One of the barriers of GDMT implementation appears to be concerns about the potential development of drug-related adverse events (AEs), particularly in high-risk patients. This study aimed to evaluate whether advanced HFrEF (AHF) patients can be up-titrated safely and whether AHF predisposes individuals to the occurrence of putatively drug-related AEs. Methods: A total of 373 HFrEF patients with documented baseline, 2 months, and 12 months visits were analyzed for utilization and target dosages (TDs) of HF drugs. Successful up-titration and AEs were evaluated for different stages of HF reflected by N-terminal pro-B type natriuretic peptide (NT-proBNP) (<1000 pg/mL, 1000–2000 pg/mL, >2000 pg/mL). Results: A stepwise increase in HF medications was observed for all drug classes during follow-up. At 12 months, 73%, 75%, 62%, 86%, and 45% of patients received ≥90% of TDs of beta-blockers (BBs), renin–angiotensin system inhibitors (RASis), mineralocorticoid receptor antagonists (MRAs), sodium–glucose cotransporter-2 inhibitors (SGLT2 i), and triple-therapy, respectively. Predictors of successful up-titration in logistic regression were baseline HF drug TDs, estimated glomerular filtration rate (eGFR), and potassium, but not NT-proBNP or age. The development of AEs was rare, with hyperkalemia as the most common event (34% at 12 months). AEs were comparable in all stages of HF. However, the development of hyperkalemia was more frequent in patients with higher NT-proBNP and also accounted for most cases of incomplete up-titration. Conclusions: This study suggests that with dedicated protocols and frequent visits, GDMT can be successfully implemented across all stages of HFrEF, including patients with AHF. Full article

Background: This study presents an innovative approach to cardiovascular disease (CVD) risk prediction based on a comprehensive analysis of clinical, immunological and biochemical markers using mathematical modelling and machine learning methods. Baseline data include indices of humoral and cellular immunity (CD59, CD16, IL-10, CD14, CD19, CD8, CD4, etc.), cytokines and markers of cardiovascular disease, inflammatory markers (TNF, GM-CSF, CRP), growth and angiogenesis factors (VEGF, PGF), proteins involved in apoptosis and cytotoxicity (perforin, CD95), as well as indices of liver function, kidney function, oxidative stress and heart failure (albumin, cystatin C, N-terminal pro B-type natriuretic peptide (NT-proBNP), superoxide dismutase (SOD), C-reactive protein (CRP), cholinesterase (ChE), cholesterol, and glomerular filtration rate (GFR)). Clinical and behavioural risk factors were also considered: arterial hypertension (AH), previous myocardial infarction (PICS), aortocoronary bypass surgery (CABG) and/or stenting, coronary heart disease (CHD), atrial fibrillation (AF), atrioventricular block (AB block), and diabetes mellitus (DM), as well as lifestyle (smoking, alcohol consumption, physical activity level), education, and body mass index (BMI). Methods: The study included 52 patients aged 65 years and older. Based on the clinical, biochemical and immunological data obtained, a model for predicting the risk of premature cardiovascular aging was developed using mathematical modelling and machine learning methods. The aim of the study was to develop a predictive model allowing for the early detection of predisposition to the development of CVDs and their complications. Numerical methods of mathematical modelling, including Runge–Kutta, Adams–Bashforth and backward-directed Euler methods, were used to solve the prediction problem, which made it possible to describe the dynamics of changes in biomarkers and patients’ condition over time with high accuracy. Results: HLA-DR (50%), CD14 (41%) and CD16 (38%) showed the highest association with aging processes. BMI was correlated with placental growth factor (37%). The glomerular filtration rate was positively associated with physical activity (47%), whereas SOD activity was negatively correlated with it (48%), reflecting a decline in antioxidant defence. Conclusions: The obtained results allow for improving the accuracy of cardiovascular risk prediction, and form personalised recommendations for the prevention and correction of its development.

This study included 221 patients with COVID-19 who were admitted to the emergency department of Avicenne Hospital in Rabat between August 2020 and August 2021. Patients were divided into three groups according to their D-dimer levels (<1, 1–2, and >2 µg/mL). Adjusted and unadjusted logistic regression analyses were performed to assess the association between elevated D-dimer levels and in-hospital mortality. Pearson’s correlation analysis was performed to explore the relationship between D-dimer levels and various biological and clinical parameters. The results revealed a statistically significant difference in the mean (SD) age among the three groups (p = 0.006). Analysis showed a statistically significant difference in the means (SD) of oxygen saturation, duration of hospital stay, and breathing rate among the three independent groups of COVID-19 patients. Patients with elevated D-dimer levels (greater than 2 µg/mL) experienced worse outcomes than those in the other groups, with severity, transfer to intensive care, and in-hospital mortality of 55 (40.7%), 35 (16%), and 24 (11%) patients, respectively, with p-values of 0.048, 0.002, and 0.002, respectively. Patients in the D-dimer > 2 µg/mL group had significantly higher C-reactive protein (CRP), lactate dehydrogenase, urea, cardiac troponin, B-type natriuretic peptide, and ferritin levels than those in the other two groups. The p-value was significant among the three groups (p = 0.044, p = 0.001, and p < 0.001). Age and elevated D-dimer levels (greater than 2 µg/mL) were associated with mortality in patients diagnosed with COVID-19. Correlation analysis indicated that D-dimer in COVID-19 patients is associated with worsening respiratory, hepatic, cardiac, and coagulation parameters, suggesting their utility as an integrative marker of disease severity. D-dimer levels > 2 µg/mL were identified as an independent risk factor for COVID-19 in-hospital mortality. Measuring and monitoring D-dimer levels can assist clinicians in taking timely actions and predicting the prognosis of patients with COVID-19. Full article

Background: High plasma levels of Galectin-3 (Gal-3) and uric acid (UA) are associated with a decline in renal function in different populations. However, this association has not yet been studied in patients with coronary artery disease (CAD). Methods: We included 556 patients with stable CAD. Plasma levels of Gal-3, UA, N-Terminal probrain natriuretic peptide (NT-proBNP), calcidiol, fibroblast growth factor 23, phosphate, parathormone, and klotho were assessed at baseline. The primary outcome was the percentage decrease in eGFR; the secondary outcomes were the absolute decrease in eGFR and achieving a reduction of ≥20% in this parameter. Results: Age was 63.1 ± 12.2 years, and 73.9% of patients were male. The median eGFR was 86.77 (72.27, 97.85) mL/min/1.73 m². After 3.47 (2.10–5.72) years of follow-up, eGFR declined by 3.62% [−2.07–13.82]. Baseline UA (0.012 [CI95% 0.003, 0.020]; p = 0.008), Gal-3 (0.0153 [CI95% 0.001, 0.029]; p = 0.037), and NT-proBNP (0.017 [CI95% 0.000–0.025]; p = 0.027) were independent positive predictors of the percentage decrease in eGFR, while calcidiol (−0.005 [CI95% −0.009, −0.002]; p = 0.005) was an inverse predictor of this outcome. Similarly, UA and Gal-3 were positive independent predictors of the absolute decline in eGFR (0.009 [0.003, 0.017]; p = 0.004 and 0.012 [0.001, 0.023]; p = 0.031, respectively), while calcidiol was inversely associated (−0.003 [−0.005]–[−0.001]; p = 0.020). Uric acid (1.237 [1.046–1.463]; p = 0.013) and NT-proBNP (1.000 [1.000–1.001]; p = 0.049) levels were positive independent predictors of a ≥20% decrease in eGFR. In patients with eGFR ≥ 60 mL/min/1.73 m², UA was the only biomarker independently associated with renal function decline. Conclusions: In patients with CAD and normal or mildly reduced renal function, UA and Gal-3 plasma levels are independent positive predictors of a future decrease in eGFR. These findings could lead to a change in the approach to patients with CAD in the future. Full article

The insulin-like growth factor binding protein, acid-labile subunit (IGFALS), plays a crucial role in glucose metabolism and immune regulation, key processes in recovery from surgery. Here, we studied the perioperative serum IGFALS dynamics and explored potential clinical implications. A total of 79 patients undergoing elective cardiac surgery with implementation of cardiopulmonary bypass had their serum isolated at baseline, 24 h, seven days, and three months postoperatively to assess serum concentrations of IGFALS and insulin growth factor 1 (IGF-1). Markers of perioperative injury included troponin I (TnI), high-mobility group box 1 (HMGB-1), and heat shock protein 60 (Hsp-60). Inflammatory status was assessed via interleukin-6 (IL-6) and interleukin-8 (IL-8). Additionally, we measured in vitro cytokine production to viral stimulation of whole blood and monocytes. Surrogates of neuronal distress included neurofilament light chain (NF-L), total tau (τ), phosphorylated tau at threonine 181 (τp181), and amyloid β40 and β42. Renal impairment was defined by RIFLE criteria. Cardiac dysfunction was denoted by serum N-terminal pro-brain natriuretic peptide (NT-proBNP) levels. Serum IGFALS levels declined significantly after surgery and remained depressed even at 3 months. Administration of acetaminophen and acetylsalicylic acid differentiated IGFALS levels at the 24 h postoperatively. Serum IGFALS 24 h post-operatively correlated with production of cytokines by leukocytes after in vitro viral stimulation. Serum amyloid-β1-42 was significantly associated with IGFALS at baseline and 24 h post-surgery Patients discharged home had higher IGFALS levels at 28 days and 3 months than those discharged to healthcare facilities or who died. These findings suggest that IGFALS may serve as a prognostic biomarker for recovery trajectory and postoperative outcomes in cardiac surgery patients. Full article

Background/Objectives: Sotatercept has demonstrated efficacy in pulmonary arterial hypertension (PAH), but its use has not been studied in patients with Group 3 pulmonary hypertension (PH). Additionally, patients with connective tissue disease-associated PAH (CTD-PAH) were underrepresented in the STELLAR trial. Given the limited treatment options for pulmonary hypertension in patients with interstitial lung disease (PH-ILD), this study aimed to evaluate the use of sotatercept in CTD-PAH patients with concomitant ILD. Methods: Eligible patients (n = 7) had a confirmed diagnosis of CTD-PAH with concomitant ILD. The patients were already receiving background PAH therapy. Baseline hemodynamic and clinical measurements were reassessed after 24 weeks of sotatercept therapy. The variables assessed included six-minute walk distance (6MWD), pulmonary vascular resistance (PVR), echocardiographic right ventricular systolic pressure (eRVSP), N-terminal pro-brain natriuretic peptide (NT-proBNP) levels, World Health Organization (WHO) functional class, and supplemental oxygen requirements. Results: The study included seven patients with a mean age of 57 years (range: 39–73 years). After 24 weeks, the mean 6MWT distance increased from 211 m to 348 m (p < 0.01). Mean PVR decreased from 7.77 WU at baseline to 4.53 WU (p < 0.01). Mean eRVSP decreased from 79.43 mmHg to 54.14 mmHg (p < 0.01). NT-proBNP decreased from 3056.86 pg/mL to 1404.29 pg/mL (p < 0.01). The WHO functional class and supplemental oxygen requirements improved in all patients. Conclusions: Sotatercept was tolerated in patients with CTD-PAH and ILD, with no evidence of adverse respiratory effects. When added to foundational PAH therapy, sotatercept resulted in significant improvements across multiple parameters. These findings suggest that sotatercept may be a promising therapeutic option as an adjunctive treatment in this patient population. Full article

Background/Objectives: We aimed to identify the factors associated with clinically important changes in quality of life (QoL) of real-world heart failure (HF) patients. Methods: This is a single-centre, prospective cohort study including 419 patients at an HF clinic between January 2013 and February 2020. QoL was assessed regularly using Minnesota Living with Heart Failure Questionnaire (MLHFQ). We used five nested linear mixed-effects models to account for QoL measurements between patients and within-patient. Models were adjusted for time, sociodemographic factors, comorbidities, self-care adherence, and HF severity factors. Results: Median age was 78 years, 54.4% of patients were female, and 49.6% had left ventricle ejection fraction ≥ 50%. At baseline, 62.5% of patients were New York Heart Association (NYHA) class II. Median N-terminal-pro-B type natriuretic peptide level was 1454 pg/mL. Mean MLHFQ total score at baseline was 25 points (95%CI: 22.97–27.60). Having an implanted cardiac resynchronization therapy-pacemaker (CRT-P) was associated with moderate to large improvement in QoL (−13.55 points, 95%CI: −22.45–−4.65). NYHA class II and estimated glomerular filtration rate < 30 mL/min/1.73 m² were associated with small to moderate QoL deterioration (9.74 points, 95%CI: 6.74–12.75 and 5.82 points, 95%CI: 1.17–10.47, respectively). NYHA classes III or IV and a recent HF hospitalization were associated with large to very large QoL deterioration (28.39 points, 95%CI: 23.82–32.96; 60.59 points, 95%CI: 34.46–86.72; and 26.91 points, 95%CI: 21.80–32.03, respectively). Conclusions: CRT-P implantation, NYHA class and HF hospitalization are associated with the most clinically important QoL changes. Full article

Post-acute sequelae of COVID-19 have been associated with an elevated risk of thromboembolism and adverse cardiovascular events (CVEs). We aim to evaluate whether alterations in poorly studied hemostatic and endothelial proteins are associated with CVEs in patients previously admitted to the ICU and evaluated one year post-discharge. We carried out a cross-sectional study involving 63 COVID-19 patients previously admitted to the ICU one year post-discharge. Plasma levels of factor IX (coagulation factor), protein C, protein S (natural anticoagulant), and von Willebrand factor (VWF, an endothelial marker) were measured using a Luminex 200™ analyzer. Generalized linear models (GLMs) were used to assess the association of these coagulation proteins with CVEs and N-terminal pro-B-type natriuretic peptide (NT-proBNP). We found that lower levels of factor IX (p = 0.011), protein C (p = 0.028), and protein S (p = 0.008) were associated with CVEs one year after ICU discharge. Additionally, at the one-year follow-up, we found lower levels of factor IX (p = 0.002) and higher levels of VWF (p = 0.006) associated with higher levels of NT-proBNP, underscoring the involvement of both hemostatic imbalance and persistent endothelial dysfunction. Our findings revealed a gender-specific pattern of associations with NT-proBNP levels. These findings highlight the significant role of persistent hemostatic imbalance and endothelial dysfunction in the development of cardiovascular abnormalities among COVID-19 survivors discharged from the ICU.

Background: Cardiovascular diseases (CVDs) remain a leading cause of morbidity and mortality, despite advances in treatment. Early detection of vascular aging is critical, as preclinical atherosclerosis often remains undiagnosed. AI-determined vascular age, originally developed using carotid-femoral pulse wave velocity (cf-PWV), may help to identify individuals at elevated risk. This study aimed to evaluate the clinical utility of an alternative AI-determined vascular age model based on the arterial velocity pulse index (AVI) and arterial pressure volume index (API) in a Japanese hospital-based cohort. Methods: This retrospective, exploratory study analyzed electronic health records of 408 patients from Yokohama City University Hospital. This study was approved by the Clinical Research Ethics Committee (approval numbers: B180300040, F240500007), and patient consent was obtained through an opt-out process. AI-determined vascular age was estimated using a Generalized Additive Model (GAM) with backward stepwise regression, substituting cf-PWV with AVI and API. Correlations with chronological age were assessed, and comparisons of cardiovascular and renal function markers were performed across age-stratified groups. Results: AI-determined vascular age showed a strong correlation with chronological age (p < 0.05). Significant differences were observed in cardiac diastolic function parameters, B-type natriuretic peptide (BNP), and estimated glomerular filtration rate (eGFR) between the highest and lowest quintiles of AI-determined vascular age. Conclusions: AI-determined vascular age using AVI and API appears to be a feasible surrogate for cf-PWV in clinical settings. This index may aid in stratifying vascular aging and identifying individuals who could benefit from early cardiovascular risk management. Full article

Background/Objectives: Pulmonary hypertension (PH) is a progressive disorder with high morbidity and mortality, partly driven by chronic inflammation. Soluble urokinase plasminogen activator receptor (suPAR) reflects immune activation. We evaluated whether suPAR is altered in Group 1 and Group 4 PH and its association with clinical, echocardiographic, and laboratory parameters. Methods: We enrolled 44 PH patients (36 in Group 1, 8 in Group 4) and 45 healthy controls. All underwent clinical and echocardiographic assessments; right heart catheterization was performed in the PH patients. Serum suPAR was measured by ELISA. N-terminal pro B-type natriuretic peptide (NT-proBNP) and C-reactive protein (CRP) were also assessed. Results: The suPAR plasma levels in the PH group were between 23.91 and 960.8 pg/mL (median: 73.14 p25: 62.77, p75: 167.13). suPAR was significantly higher in PH versus controls (73.14 [62.77–167.13] vs. 65.52 [53.06–80.91] pg/mL; p = 0.012). In logistic regression, systolic blood pressure, erythrocyte sedimentation rate, NT-proBNP, and suPAR independently predicted PH. suPAR correlated negatively with six-minute walk distance (r = −0.310) and tricuspid annular plane systolic excursion (r = −0.295) but positively with systolic pulmonary artery pressure (r = 0.241). On multivariate analysis, six-minute walk distance was the only independent correlate of suPAR (p = 0.004). suPAR levels did not differ between Group 1 and Group 4 PH. Conclusions: suPAR is elevated in Group 1 and Group 4 PH and correlates with functional and echocardiographic indices of disease severity. Larger prospective studies are needed to determine suPAR’s role in diagnosis, risk stratification, and therapeutic decision-making. Full article

Right heart failure (RHF) is a major cause of morbidity and mortality, often resulting from pulmonary arterial hypertension and characterized by impaired calcium (Ca²⁺) handling and maladaptive remodeling. Phosphodiesterase 9A (PDE9A), a cGMP-specific phosphodiesterase, has been proposed as a potential contributor to RHF pathogenesis by suppressing the cardioprotective cGMP–PKG signaling pathway—a conclusion largely extrapolated from left-sided heart failure models. This review examines existing evidence regarding PDE9A’s role in RHF, focusing on its effects on intracellular calcium cycling, fibrosis, hypertrophy, and contractile dysfunction. Data from preclinical models demonstrate that pathological stress upregulates PDE9A expression in cardiomyocytes, leading to diminished PKG activation, impaired SERCA2a function, RyR2 instability, and increased arrhythmogenic Ca²⁺ leak. Pharmacological or genetic inhibition of PDE9A restores cGMP signaling, improves calcium handling, attenuates hypertrophic and fibrotic remodeling, and enhances ventricular compliance. Early-phase clinical studies in heart failure populations suggest that PDE9A inhibitors are well tolerated and effectively augment cGMP levels, although dedicated trials in RHF are still needed. Overall, these findings indicate that targeting PDE9A may represent a promising therapeutic strategy to improve outcomes in RHF by directly addressing the molecular mechanisms underlying calcium mishandling and myocardial remodeling.

In chronic kidney disease (CKD), various disorders occur that worsen with the progression of CKD. These include increased levels of hormones such as adiponectin, leptin, and prolactin, changes in feedback loops and metabolism, and decreased renal clearance, contributing to significant morbidity and mortality. We conducted a cross-sectional observational study on 157 randomly selected patients with various stages of chronic kidney disease, 29% of whom had diabetes. We recorded clinical and usual laboratory data. We determined muscle mass and adipose tissue mass using bioimpedance. In addition, we measured serum prolactin levels, tumor necrosis factor-alpha (TNF-α), Interleukin 6 (IL-6), and Interleukin-1 beta (IL-1β). N-terminal pro-B-type natriuretic peptide (NT-proBNP) was evaluated as a marker of cardiac function. We evaluated the relation between prolactin, TNF-α, IL-6, IL-1β, and NT-proBNP by bivariate and multivariate analysis. In bivariate analysis, we recorded associations of prolactin with inflammatory markers: TNF-α (r = 0.65, p < 0.001), IL-6 (r = 0.66, p < 0.001), and IL-1β (r = 0.25, p = 0.002). In multivariate analysis we observed that serum prolactin values are associated with IL-1β [median (25th–75th percentile): [−0.001 (−0.001; −0.00003), p = 0.037], muscle mass [−0.03 (−0.04; −0.01), p = 0.003], and NT-proBNP [0.0001 (0.0001; 0.0001)] p < 0.001 In conclusion, in chronic kidney disease, prolactin is associated with inflammatory markers (IL-1β, TNF-α, IL-6), and nutritional status. Additionally, prolactin has been linked to NT-ProBNP, a marker of cardiac function. Full article

Objectives: Kawasaki Disease (KD) is an acute vasculitis associated with systemic inflammation. This study aimed to investigate the level and clinical significance of soluble ST2 (sST2) in children with KD. Methods: A retrospective analysis was conducted on 287 pediatric KD patients treated at the Pediatric Cardiology Department of Shengjing Hospital, China Medical University, from November 2021 to December 2022. Patients were stratified into subgroups based on the presence of myocardial damage (MD), coronary artery lesions (CAL), multi-organ involvement (MOD; ≥3 organs) and/or intravenous immunoglobulin-resistant KD (IVIG-R KD). In each group, we analyzed the correlation between sST2 levels and various laboratory parameters, including white blood cell count (WBC), hemoglobin (HB), platelet count (PLT), C-reactive protein (CRP), interleukin-6 (IL-6), erythrocyte sedimentation rate (ESR), N-terminal pro-brain natriuretic peptide (NT-pro BNP), D-dimer, and albumin (ALB). Results: Patients in the CAL group were significantly younger and predominantly male (p < 0.05). In the MD, CAL, MOD, and IVIG-R KD groups, levels of sST2, CRP, NT-pro BNP, and D-dimer were significantly higher than in their respective comparison groups (p < 0.05). sST2 showed weak positive correlations with WBC, CRP, IL-6, NT-pro BNP, and D-dimer, and weak negative correlations with HB and ALB (p < 0.05). sST2, HB, and IL-6 were identified as independent risk factors for MOD (p < 0.05). sST2 and HB were independent risk factors for IVIG-R KD (p < 0.05). Among acute-phase patients, four cases had sST2 levels > 200 ng/mL—all were classified as IVIG-R KD and MOD; three of these also developed coronary artery aneurysms (CAA). Conclusions: Elevated sST2 levels in the acute phase of KD may serve as a clinical indicator of IVIG-R KD, CAA, MOD, and MD. Full article

The aim of this study was to evaluate and synthesize the existing evidence on N-terminal pro-brain natriuretic peptide (NT-proBNP) and brain natriuretic peptide (BNP) as biomarkers for preeclampsia as compared with a healthy pregnant group, but also comparing them in early-onset preeclampsia (EOP) versus late-onset preeclampsia (LOP). Five electronic databases, PubMed, EMBASE, Web of Science, Scopus, and LILACS, were searched for studies on pregnant women comparing NT-proBNP and BNP levels in preeclampsia vs. healthy pregnancies and EOP vs. LOP. From the 752 identified records, 31 studies were included in the review, referring to 3915 participants. When comparing PE to healthy pregnancies and EOP to LOP, there was a considerable increase in NT-proBNP levels in the PE group, respectively, in EOP: 206.19 pg/mL (95% CI 139.68–272.69) (p ≤ 0.001) in the PE group, and 182.42 pg/mL (95% CI 99.65–265.19) (p ≤ 0.001) in the EOP group. Regarding BNP, the levels were higher in the PE group (30.13 (95% CI 17.22–43.04), p ≤ 0.001), respectively in the EOP group (33.35 pg/mL (95% CI 20.26–46.43), p ≤ 0.001). NT-proBNP and BNP levels are consistently elevated in preeclampsia compared to healthy pregnancies and in EOP compared to LOP. Full article

Background: Left ventricular filling pressure (LVFP) is pivotal in heart failure management, yet non-invasive assessment remains challenging. While echocardiography is the first line, cardiovascular magnetic resonance (CMR) offers enhanced accuracy. This study evaluates the interplay between CMR-derived LVFP and echocardiography, focusing on sex differences and correlations with N-terminal pro-brain natriuretic peptide (NT-proBNP). Methods: In this prospective study, 222 patients with CMR-derived LVFP > 14 mmHg underwent transthoracic echocardiography (TTE) and CMR. Sex-specific CMR equations (incorporating left atrial volume and ventricular mass) were used to estimate pulmonary capillary wedge pressure (PCWP). Correlations between imaging parameters and NT-proBNP were assessed. Results: CMR-derived LVFP showed no sex-based differences (p = 0.3143), unlike echocardiographic indices: women had higher E/e′ (p < 0.0001) and lower lateral mitral annular velocities (p = 0.0159). CMR-derived LVFP correlated strongly with NT-proBNP (r = 0.47, p < 0.0001), outperforming E/e′ (r = 0.41). Stratification by CMR PCWP tertiles revealed higher NT-proBNP (p = 0.0003), left atrial volumes (p < 0.0001), and septal thickness (p < 0.0001) in the highest tertiles. CMR-derived LVFP demonstrated superior diagnostic accuracy (AUC = 0.754 vs. 0.740 for E/e′) in identifying elevated NT-proBNP (>400 pg/mL). Sex-independent CMR measures contrasted with echocardiography, where parameters like left atrial volume varied by sex (p = 0.012). Conclusions: CMR-derived LVFP is a robust, sex-independent biomarker strongly linked to NT-proBNP, offering superior diagnostic performance over echocardiography. Its integration with echocardiographic indices enhances the non-invasive assessment of cardiac filling pressures, advocating a synergistic imaging approach to refine heart failure management.
