by Jan-Hendrik van den Bruck, Jan-Hendrik Schipper, Katharina Seuthe, Sebastian Dittrich, Theodoros Maximidou, Arian Sultan, Jana Ackmann, Jonas Wörmann, Cornelia Scheurlen, Jakob Lüker and Daniel Steven

Background/Objectives: Catheter ablation is an established therapy for ventricular tachycardia (VT), though outcomes remain limited in patients with non-ischemic dilated cardiomyopathy (NIDCM) due to complex arrhythmogenic substrates. Late iodine enhancement computed tomography (LIE-CT) offers a promising alternative to cardiac MRI for preprocedural substrate visualization. This study evaluated procedural characteristics and outcomes of LIE-CT-supported VT ablation versus conventional mapping (CM) in NIDCM patients. Methods: NIDCM patients undergoing VT ablation between January 2022 and August 2024 were retrospectively analyzed. LIE-CT data were processed using inHEART software. Patients were matched 1:1 by propensity score based on baseline characteristics, electrical storm, and prior ablations. Results: A total of 46 patients (mean age 59 ± 16.4 years, 74% male) were included (23 LIE-CT, 23 CM). Procedure durations were comparable (231.5 ± 74.2 vs. 220.2 ± 70.2 min, p = 0.5), but mapping time (35.9 ± 15.3 vs. 54 ± 5 min, p < 0.001) and fluoroscopy time (14.7 ± 5.1 vs. 21.3 ± 10.6 min, p = 0.02) were significantly shorter with LIE-CT. Epicardial access was more frequent (52% vs. 26%, p < 0.001), and bipolar ablation for intramural scar was performed in 17% of LIE-CT cases. There were no significant differences in acute kidney injury or 30-day mortality. At a median follow-up of 367 days, VT-free survival was 57% with LIE-CT and 52% with CM (p = 0.8). Conclusions: LIE-CT-supported VT ablation and substrate visualization was safe, without additional risk of acute kidney injury, and enabled more efficient and targeted VT ablation. Prospective studies are warranted to assess its impact on long-term outcomes in NIDCM patients. Full article

Background: The widespread use of cardiac magnetic resonance imaging (MRI) in clinical practice has enabled the identification of numerous patients with evident damage from previous myocarditis, whether known or unknown. For years, myocardial fibrosis has been a topic of interest due to its established correlation with arrhythmic events in various clinical settings, including ischemic heart disease, dilated cardiomyopathy, and hypertrophic cardiomyopathy. MIBG scintigraphy is a method widely used in patients who are candidates for defibrillator implantation or have experienced heart failure. This examination evaluates the sympathetic innervation of the myocardium. Objective: To assess the real arrhythmogenic risk of non-ischemic scars identified in symptomatic or asymptomatic patients through the use of MIBG. Methods: Patients were retrospectively selected based on the presence of non-ischemic myocardial fibrosis detected by cardiac MRI, consistent with a myocarditis outcome (even in the absence of a clear history of myocarditis). These patients underwent myocardial scintigraphy with MIBG using a tomographic technique. Results: A total of 50 patients (41 males, mean age 51 ± 16 years) who underwent MRI from 2019 to June 2024 were selected. The primary indication for MRI was ventricular ectopic extrasystoles detected on Holter ECG (n = 12, 54%), while five patients underwent MRI following a known acute infectious event (23%, including three cases of COVID-19 infection). All symptomatic patients presented with chest pain in the acute phase, accompanied by elevated hsTNI levels (mean value: 437 pg/mL). The MRI findings showed normal ventricular volumes (LV: 80 mL/m2, RV: 81 mL/m2) and normal ejection fractions (56% and 53%, respectively). The mean native T1 mapping value was 1013 ms (normal range: 950–1050). T2 mapping values were altered in the 5 patients who underwent MRI during the acute phase (mean value: 57 ms), without segmentation. Additionally, three patients had non-tamponade pericardial effusion. All patients exhibited LGE (nine subepicardial, seven midwall, six patchy). All patients underwent myocardial scintigraphy with MIBG at least 6 months after the acute event, with only one case yielding a positive result. This patient, a 57-year-old male, had the most severe clinical presentation, including more than 65,000 premature ventricular beats (PVBs) and multiple episodes of paroxysmal supraventricular tachycardia (PSVT) recorded on Holter ECG. MRI findings showed severe left ventricular dysfunction, a slightly dilated LV, and midwall LGE at the septum, coinciding with hypokinetic areas. Conclusions: MIBG scintigraphy could be a useful tool in assessing arrhythmic risk in patients with previous myocarditis. It could help reduce the clinical burden of incidental findings of non-ischemic LGE, which does not appear to be independently associated with an increased risk profile. Full article

Background and Objectives: Early repolarization (ER), previously considered benign for many years, is now recognized as a substantial risk factor for malignant arrhythmia, coronary artery disease, and mortality. The ER pattern, previously regarded as a benign electrocardiographic characteristic, has lately been demonstrated to have a strong association with malignant arrhythmias, coronary artery disease, and elevated death rates. This study seeks to illustrate the prognostic significance of QT interval (QTc) prolongation on electrocardiograms for acute coronary syndrome and death in emergency cases. Prolongation of QTc duration on electrocardiography in emergency room cases may serve as a possible predictor for acute coronary syndrome and mortality. Materials and Methods: A retrospective study was conducted on 924 patients diagnosed with ER in the emergency department from 2020 to 2023. The QTc durations, serum glucose levels, troponin I levels, and additional auxiliary data of the patients were assessed. The alteration in the aVR derivation, often overlooked and deemed insignificant, was compared with clinical severity in ER cases. Results: The average age of the 924 patients in the study was 48.43 (9.65) years, with 30.7% being female. In the non-cardiac group, the mean age was 51.67 (7.98) years, with 738 females (31.9%). The QTc interval in the patient group was 409.54 (33.46) ms, while in the control group it was 411.57 (27.91) ms (p < 0.001). The one-year death rate was 49 (5.3%) for the ER group and nine (0.9%) for the follow-up group. The most common comorbid condition in both groups was tobacco and/or tobacco product intake. Univariate and multivariate regression analyses conducted for both ER types and mortality indicated that QTc prolongation may serve as a predictive factor (p < 0.001). The sensitivity and specificity of prolonged QTc in predicting acute coronary syndrome and mortality were determined to be 76% at the lowest and 98% at the highest levels in ER cases (p < 0.001). The Kaplan–Meier survival analysis for ER types revealed 321 days for the horizontal type and 363 days for the ascending type. Conclusions: Prolonged QTc duration in early repolarization cases may serve as an independent predictor of acute coronary syndrome and mortality. Full article

Background/Objectives: Heart failure (HF) often develops from a prolonged asymptomatic phase where early detection could prevent progression. Pre-heart failure (pre-HF) populations—those with risk factors (Stage A) or subclinical myocardial changes (Stage B)—are critical for intervention. Cardiac magnetic resonance (CMR) with T1 and extracellular volume (ECV) mapping offers a non-invasive approach to detect early myocardial changes in these groups. This systematic review evaluates the role of T1 and ECV mapping in pre-HF populations, focusing on their diagnostic and prognostic utility. Methods: A systematic search of PubMed, EMBASE, and Cochrane was conducted up to April 2025, identifying 17 studies that met inclusion criteria. Data was extracted directly into Excel, and methodological quality was assessed using the Newcastle–Ottawa Scale (NOS) for cohort and cross-sectional studies and AMSTAR-2 for systematic reviews and meta-analyses. A meta-analysis was performed using Review Manager (RevMan) to compare T1 and ECV values between pre-HF and control groups. Results: Studies consistently reported elevated T1 (989.6–1415.41 milliseconds) and ECV (25.7–42.81%) in pre-HF groups compared to controls (T1: 967–1310.63 ms, ECV: 23.5–29.9%). Meta-analysis showed a significant increase in T1 (MD: 27.62 ms, 95% CI: 8.04–47.19, p < 0.006) and ECV (MD: 2.97%, 95% CI: 1.88–4.06, p < 0.00001) in pre-HF groups. RQS scores ranged from 17.2% to 77.8% (mean: 37.9%), and NOS scores ranged from 5 to 8 (mean: 6.2), reflecting variability in study quality. The AMSTAR-2 rating for the systematic review was moderate. Conclusions: T1 and ECV mapping enhance CMR-based detection of early myocardial changes in pre-HF, offering a promising non-invasive approach to predict HF risk. However, variability in study quality, small sample sizes, and methodological inconsistencies limit generalisability. Future research should focus on standardised protocols, prospective designs, and multi-center studies to integrate these techniques into clinical practice, potentially guiding preventive therapies such as SGLT2is and tafamidis.

Radiographic axial spondyloarthritis (r-axSpA) is associated with increased cardiovascular disease (CVD) risk. The coronary artery calcification (CAC) score, an atherosclerosis burden indicator that predicts CVD risk, is not well studied in r-axSpA. This study investigates CAC scores in patients with r-axSpA compared to controls without rheumatic disease and factors associated with CAC scores in r-axSpA patients. Fifty-eight r-axSpA patients from southwestern Sweden were assessed cross-sectionally using clinical disease measures, physical function, spinal mobility, lipid profiles, inflammation markers, and long-term time-averaged C-reactive protein (CRP). Four controls per patient were selected from the Swedish CArdioPulmonary bioImage Study (SCAPIS). CAC was scored on cardiac computed tomography (CT) using the Agatston method. The presence of CAC in the right coronary artery (RCA) was higher in patients compared to controls. However, no significant difference in total CAC scores was observed between r-axSpA patients and controls, despite numerically higher total CAC scores in patients. In r-axSpA patients, CAC scores correlated positively with time-averaged CRP, reduced physical function, and impaired spinal mobility. These findings suggest that chronic inflammation may contribute to coronary calcification and CVD risk in r-axSpA, highlighting the need for effective anti-inflammatory treatments. Further research is warranted to explore the association between coronary calcification, spinal immobility, and limitations in physical function. Full article

Background and Objectives: Electrocardiography (ECG), though non-specific, is widely applied as a valuable tool in the diagnostic work-up of acute myocarditis. Cardiac magnetic resonance (CMR) has become a key non-invasive tool. This study assessed the association of ECG findings (at baseline), echocardiographic parameters, circulating biomarkers, and CMR imaging features (myocardial edema and late gadolinium enhancement—LGE) in patients with acute myocarditis. Materials and Methods: This single-center, retrospective observational study included 86 patients admitted with acute myocarditis from January 2021 to December 2024. Data collected included demographics, clinical presentation, ECG, echocardiography, biomarkers (CRP, troponin I), and CMR imaging performed during hospitalization and at the six-month follow-up. Based on ECG findings, patients were stratified into three groups: no ST elevation or T-wave abnormalities (NSTG, n = 27), T-wave abnormalities (TWAG, n = 24), and ST elevation (STEG, n = 35). Results: We enrolled 86 patients (median age: 26 years; 87.2% male), and the most frequent CMR findings were either LGE (80.2%) and/or myocardial edema (75.6%). The prevalence of edema and LGE was higher in the STEG (both 91.2%) compared to TWAG (65.2%, 77.3%, respectively) and NSTG (57.7, 65.4%, respectively) (p < 0.05). Peak troponin levels were also higher in the STEG than other groups (p = 0.005). In logistic regression analysis, TWAs were independently associated with both edema (OR = 3.15, 95% CI: 1.078–9.189, p = 0.036) and LGE (OR = 3.93, 95% CI: 1.256–12.276, p = 0.019). Biomarkers were associated with lower LVEF in univariate analysis, but not in multivariate models. Conclusions: ECG abnormalities, particularly STE and TWA, are common in acute myocarditis and significantly associated with CMR findings. Although CMR remains essential for definitive diagnosis and risk stratification in acute myocarditis, ECG may serve as a valuable initial screening tool in the context of a multimodal diagnostic approach.

Background: Large vessel occlusion (LVO) strokes account for a significant proportion of ischemic strokes and are often cardioembolic in origin, particularly following atrial fibrillation (AF) with thrombus formation in the left atrial appendage (LAA). Although direct oral anticoagulation (DOAC) therapy reduces stroke risk in AF, anatomical and flow-related factors may still allow thrombi to form and persist, revealing the limitations of anticoagulation in high-risk patients. Examining structural and hemodynamic factors contributing to thrombus persistence is essential for optimizing patient management. Methods: We retrospectively analyzed 169 AF patients with LVO stroke who underwent cardiac CT (cCT) during acute stroke assessment. Patients were categorized based on the presence or absence of persistent LAA thrombi and further stratified by DOAC status. LAA volume, blood stasis and left ventricular (LV) diameter were measured. Thrombi were assessed using Hounsfield Unit (HU) analysis to evaluate potential differences in thrombus composition. Logistic regression analysis was performed to identify independent predictors of thrombus persistence with adjustment for DOAC therapy. Results: Persistent LAA thrombi were identified in 23 patients (13.6%). Patients with thrombi had significantly higher rates of stasis (p = 0.004), larger left ventricular diameters (p = 0.0019) and higher LAA volumes (p = 0.004). When adjusted for DOAC therapy, larger LAA volume (OR 1.05, p = 0.011), presence of LAA stasis (OR 6.14, p = 0.013) and increased LV diameter (OR 1.06, p = 0.006) were independent predictors of thrombus persistence. Thrombus size and HU values did not differ significantly between DOAC and non-DOAC groups. Notably, 30.4% of patients with persistent thrombi were on adequate DOAC therapy. Conclusions: LAA volume, stasis and LV enlargement predict thrombus persistence in the LAA of AF patients with LVO stroke, even under adequate DOAC therapy. These findings highlight the potential need for alternative antithrombotic strategies, including interventional LAA occlusion, and warrant further investigation into individualized stroke prevention in high-risk AF populations.

Cardiovascular disease (CVD) remains the leading global cause of morbidity and mortality, largely driven by atherosclerosis, a chronic inflammatory process involving lipids and immune cells. Although traditional lipid biomarkers such as low-density lipoprotein (LDL) and high-density lipoprotein (HDL) are well-established in CVD risk stratification, the interplay between cytokines, chemokines, growth factors (CCGFs), lipid metabolism, and hematological parameters in non-cardiac populations remains underexplored. We investigated associations between plasma cytokines and lipid-related biomarkers and their relationships with circulating blood cell counts in a cohort of 164 essentially healthy adults aged 18–44 years. CCGF profiling was performed using a proximity extension assay (PEA), and statistical correlations were adjusted for multiple testing using false discovery rate (FDR) correction. The CCGFs that were associated with HDL and apolipoprotein A1 all displayed negative associations. Several pro-inflammatory cytokines, including CCL3, IL-6, and TNFSF10, showed strong positive associations with triglycerides, remnants, non-HDL, and body mass index (BMI). Furthermore, triglycerides and remnants were consistently correlated with elevated leukocyte, neutrophil, and platelet counts. HGF and FGF-21, mainly considered as anti-inflammatory, were positively associated with BMI and negatively associated with HDL, which is compliant with a multitude of actions, depending on the local milieu and the cellular interplay. Our results support the existence of a complex immunometabolic network involving lipids, CCGFs, and blood cells, even in non-diseased individuals. The observed patterns underscore the importance of understanding the intricate cytokine–lipid–cell interactions that may occur in early pathophysiological processes and highlight their potential utility in refining cardiovascular risk assessment beyond traditional lipid metrics.

Background/Objectives: Atrial fibrillation (AF) is associated with increased epicardial adipose tissue (EAT), atrial dilation, and coronary inflammation, though causality remains unclear. Cardiac computed tomography (CCT) allows for precise quantification of EAT volume and the left atrial volume index (LAVI), along with the calculation of the fat attenuation index (FAI), indicating coronary inflammation. Combined with the Coronary Artery Disease-Reporting and Data System (CAD-RADS), these imaging markers may improve AF risk stratification. This study evaluates the association between peri-atrial EAT volumes, LAVI, CAD-RADS, and FAI scores in AF patients using advanced AI platforms. Methods: This retrospective study analyzed 122 patients presenting with angina-type pain and a low-to-intermediate likelihood of CAD, who underwent CCT. Patients were divided into two groups based on rhythm status: 42 with AF and 80 without AF. Total EAT, left atrial (LA-EAT), and bi-atrial EAT (BA-EAT) volumes were assessed, along with LAV, CAD-RADS classification, and FAI scores measured using CaRi-Heart® and syngo.via Frontier®. Results: AF patients exhibited significantly higher EAT volumes (total EAT: 231.8 ± 45.85 vs. 153.2 ± 54.14 mL, p < 0.0001; LA-EAT: 23.55 ± 6.44 vs. 15.54 ± 8.49 mL, p < 0.0001; BA-EAT: 50.24 ± 12.69 vs. 39.84 ± 15.70 mL, p = 0.0002) and elevated LAVI values (57.7 ± 11.44 vs. 45.9 ± 12.58 mL/m2, p < 0.0001). ROC analyses confirmed strong diagnostic performance of total EAT (AUC = 0.869), LA-EAT (AUC = 0.776), BA-EAT (AUC = 0.703), and the LAVI (AUC = 0.756). Higher CAD-RADS categories (2–5) were more frequent in AF, although significant differences were observed only in the lowest category (0–1; 26.2% AF vs. 47.8% non-AF, p = 0.032). Total FAI scores were also higher in AF patients (14.83 ± 10.16 vs. 12.37 ± 7.89, p = 0.044). Conclusions: Increased EAT volumes, an elevated LAVI, and higher FAI scores are significantly associated with AF, suggesting a combined structural and inflammatory substrate. EAT, the LAVI, the FAI, and CAD-RADS collectively represent valuable non-invasive imaging biomarkers for early AF risk assessment. Full article

Background: Elevated cardiac troponin (cTn) levels in patients with paroxysmal supraventricular tachycardia (PSVT) often prompt coronary artery disease evaluation, though the clinical relevance of this finding remains unclear. This study aimed to identify risk factors for cTn elevation after a PSVT episode and assess its clinical significance, including the role of coronary artery disease (CAD) and long-term outcomes. Methods: We retrospectively collected data on demographics, presenting symptoms, comorbidities, chronic antiarrhythmic medication use, tachycardia duration, admission systolic blood pressure (SBP), heart rate (HR), laboratory findings, and cardioversion method in patients presenting to the Emergency Department (ED) with PSVT over a 4-year period. Patients were stratified into two groups based on the presence or absence of troponin elevation. Individuals with elevated cTn levels and at least one cardiovascular risk factor were further evaluated for CAD. One-year outcomes included SVT recurrence, rehospitalization, ablation, and mortality. Results: Among 120 patients with PSVT, 58 (48.3%) exhibited elevated cardiac troponin (cTn) levels. Independent predictors of cTn elevation included retrosternal chest pain, absence of prior SVT history, higher admission HR, and lower SBP. A heart rate cut-off of 165 bpm was identified as optimal for predicting cTn elevation (sensitivity 62.1%, specificity 72.6%). Of the 58 cTn (+) patients, 25 underwent CAD evaluation, with only 1 case (4%) confirming significant coronary disease. At one-year follow-up (n = 118), troponin elevation was not associated with increased SVT recurrence, rehospitalization, ablation, or mortality. Similarly, CAD evaluation in troponin-positive patients did not predict outcomes. Conclusions: Troponin elevation after PSVT is frequent but not prognostically significant. It is likely due to transient myocardial stress rather than CAD, supporting a conservative, individualized approach to further testing. Full article

Background/Objectives: Cardiac involvement in systemic sclerosis (SSc) ranges from subclinical to severe. While pulmonary artery hypertension (PAH) is well-documented, the mechanism of left ventricular (LV) ischemia remains unclear. Oxygen-sensitive cardiovascular magnetic resonance (OS-CMR) imaging offers a novel approach to assessing myocardial oxygenation and ischemia. This study evaluated the changes in myocardial deoxygenation in response to stress using LV OS-CMR in SSc patients without known cardiac disease. Methods: We prospectively recruited SSc patients without prior cardiac disease or risk factors, and age- and sex-matched healthy volunteers (HVs). All participants underwent transthoracic echocardiography (TTE) and 3T CMR, including native T1 mapping, rest/stress OS-CMR, stress perfusion, and late gadolinium enhancement (LGE). The primary outcome was a change in the LV OS-CMR signal intensity (SI) after adenosine stress. Results: Thirty-three participants (23 SSc, 10 HV) were enrolled. SSc patients had significantly lower global LV OS-CMR SI compared to HV (13.4 ± 6.5 vs. 19.5 ± 3.6, p = 0.011). OS-CMR SI change ≤ 10% was observed in at least one segment in 20 (87%) SSc patients and globally in 12 (52%). LGE was present in 5 (22%) patients, and 18 (78%) had ≥1 abnormal T1 mapping segment. LV global longitudinal strain (GLS) was reduced in SSc patients compared to the HVs (−19.04 ± 3.86 vs. −21.92 ± 3.72, p = 0.045). All HVs had normal CMR and TTE findings. Conclusions: SSc patients without known cardiovascular disease or PAH demonstrated subclinical LV ischemia with an impaired myocardial oxygenation response to stress. They further demonstrated LV myocardial deformation abnormalities and LV diffuse fibrosis when compared to an age-matched control group. Our findings support the presence of early coronary microvascular dysfunction and LV myocardial fibrosis in this population, which may explain the adverse cardiovascular risk seen in this population, independent of the presence of PAH.

Introduction: Gestational diabetes mellitus (GDM) is a form of hyperglycemia that develops during pregnancy and poses risks to both the mother and fetus. In other words, it is a glucose intolerance disorder first recognized during pregnancy, specifically in the second and third trimesters, with approximately 7–14% of pregnancies worldwide being affected. Methodology: A systematic literature search was conducted across three major well-established databases; PubMed, Scopus, and ScienceDirect. The search was conducted with the aim of identifying the most suitable studies for the evaluation of fetal cardiac function using Doppler ultrasound techniques in pregnancies affected by GDM. Results: Following a comprehensive full-text assessment, 186 papers were excluded, mainly due to discrepancies in the population, unsuitable study design, publishing type, or unavailability of full-text access. Ultimately, 12 studies met all the inclusion criteria and were incorporated into the scoping review. From the studies included it was found that the conventional pulsed-wave Doppler was the most frequently used modality, assessing parameters such as the E/A ratios, myocardial performance index (MPI), and the isovolumic relaxation time (IVRT). The advanced techniques of choice included tissue Doppler imaging (TDI), speckle-tracking echocardiography (STE), dual-gate Doppler, and automated MPI. Conclusions: Doppler ultrasound techniques, particularly the advanced modalities like TDI and STE, provide valuable insights into fetal cardiac function in GDM pregnancies. Their integration into routine prenatal surveillance may enhance the early detection of cardiac dysfunction and inform timely clinical interventions. Full article

Background: Medical clearance for competitive sports is vital to safeguarding athletes’ health, particularly in high-intensity disciplines like football. In Italy, fitness assessments follow stringent protocols set by the Commissione di Vigilanza per il controllo dell’Idoneità Sportiva (COCIS), with a strong focus on cardiovascular screening. The primary goal is to prevent sudden cardiac death (SCD), a rare but catastrophic event in athletes. Methods: This paper provides an in-depth narrative review of the 2023 COCIS guidelines, examining the cardiological screening process, required diagnostic tests, management of identified cardiovascular conditions, and the protocols’ role in reducing SCD risk. Results: Comparisons with international standards underscore the effectiveness of the Italian approach. Conclusions: The COCIS 2023 guidelines provide clear, evidence-based protocols for cardiovascular risk assessment, significantly enhancing athlete safety and reducing the incidence of SCD in high-intensity sports.

Background: Arteriovenous fistulas (AVFs) may contribute to cardiac remodeling and consequently to an increased risk of heart failure and cardiovascular mortality in patients with end-stage kidney disease (ESKD). We aimed to assess cardiac changes following AVF creation and identify potential parameters associated with cardiac remodeling. Methods: In our prospective, single-center study, ESKD patients without significant pre-existing cardiac disease underwent 2D and 3D echocardiographic evaluation before and after AVF creation, along with AVF flow measurement. Cardiac remodeling was assessed using 3D indexed left and right ventricular end-diastolic volumes (LVEDVi, RVEDVi), while systolic function was assessed using longitudinal strain and 3D ejection fraction. Results: We included 20 patients (18 men; median age 73.5 years [IQR: 67–77]) with a mean AVF flow of 1140 ± 345 mL/min. At a median of 8.2 months (IQR: 7.3–9.3) following AVF creation, significant biventricular dilatation was observed: LVEDVi increased from 89 ± 14 to 97 ± 21 mL/m2 (p < 0.05) and RVEDVi from 80 ± 15 to 91 ± 18 mL/m2 (p < 0.05), while the systolic function of both ventricles did not change significantly. The right ventricle showed the most pronounced remodeling and it was independently associated with volume overload (p = 0.003) and elevated left ventricular filling pressure (p = 0.030), but not with AVF flow. Conclusions: Moderate AVF flow was associated with cardiac remodeling, primarily affecting the right ventricle. Fluid overload and left ventricular filling pressure were key factors associated with right ventricular remodeling, underscoring the need for careful fluid management and vascular access planning in ESKD patients.

Stroke is a significant global health concern characterized by the abrupt disruption of cerebral blood flow, leading to neurological impairment. Accurate and timely diagnosis—enabled by imaging modalities such as computed tomography (CT) and magnetic resonance imaging (MRI)—is essential for differentiating stroke types and initiating interventions like thrombolysis, thrombectomy, or surgical management. In parallel, recent advancements in wearable technology, particularly smart clothing, offer new opportunities for stroke prevention, real-time monitoring, and rehabilitation. These garments integrate various sensors, including electrocardiogram (ECG) electrodes, electroencephalography (EEG) caps, electromyography (EMG) sensors, and motion or pressure sensors, to continuously track physiological and functional parameters. For example, ECG shirts monitor cardiac rhythm to detect atrial fibrillation, smart socks assess gait asymmetry for early mobility decline, and EEG caps provide data on neurocognitive recovery during rehabilitation. These technologies support personalized care across the stroke continuum, from early risk detection and acute event monitoring to long-term recovery. Integration with AI-driven analytics further enhances diagnostic accuracy and therapy optimization. This narrative review explores the application of smart clothing in conjunction with traditional imaging to improve stroke management and patient outcomes through a more proactive, connected, and patient-centered approach.
