Abstract Introduction Relationship between changes in cardiac function, functional capacity, and patient-reported health status in heart failure (HF) remains incompletely defined, which may help inform endpoint selection and clarify how distinct clinical domains reflect treatment response. Methods This post hoc analysis of the randomized cardiac microcurrent (C-MIC) II trial, which evaluated the efficacy and safety of C-MIC therapy in patients with chronic HF with reduced ejection fraction on optimal guideline-directed medical therapy, included 65 ambulatory patients with non-ischaemic dilated cardiomyopathy, New York Heart Association (NYHA) Class III-IV symptoms, and baseline left ventricular ejection fraction (LVEF) 25–35%. Correlations between changes in Kansas City Cardiomyopathy Questionnaire Overall Summary Score (KCCQ-OSS), 6-minute walk distance (6MWD), core lab-assessed LVEF (primary measure) and site-assessed LVEF, and peak oxygen uptake (peak VO2) were evaluated at 4 weeks, 2 months, 3 months, 4 months, and 6 months using Pearson coefficients with 95% confidence intervals (CI). Results The mean age was 60.0 ± 9.7 years and baseline LVEF was 29.8 ± 3.3%. Baseline 6MWD was 291.4 ± 61.6 m and KCCQ-OSS was 42.6 ± 22.7. From baseline to 6 months, changes in KCCQ-OSS (n = 63) and 6MWD (n = 61) showed modest correlations with core lab-assessed LVEF (r = 0.39; 95% CI: 0.16–0.58; P = .0015 and r = 0.39; 95% CI: 0.15–0.58; P = .0022, respectively). Changes in KCCQ-OSS and 6MWD correlated strongly (n = 62; r = 0.63; 95% CI: 0.46–0.76; P < .0001). Changes in KCCQ-OSS and 6MWD did not correlate significantly with changes in peak VO2 (P = .06 and P = .30, respectively). Changes in LVEF and peak VO2 (n = 55) demonstrated modest correlation (r = 0.41; 95% CI: 0.16–0.61; P = .002). Baseline correlations with peak VO2 were weak to modest but increased at 6 months for LVEF (n = 59; r = 0.56; 95% CI: 0.35–0.71; P < .0001). Conclusion In advanced HF, improvements in health status and submaximal functional capacity associate modestly with LVEF, while LVEF correlates more closely with peak VO2. Cardiac function, functional capacity, and health status represent related but distinct domains, supporting multidimensional assessment in HF trials.

ObjectiveTo evaluate the predictive value of LA strain parameters and LASI for AF recurrence following electrical CV, and to compare them to conventional echocardiographic, biochemical, and clinical markers.MethodsIn this prospective, observational pilot study, 31 patients with persistent AF underwent electrical CV and were followed for six months. Echocardiographic evaluation included LA reservoir, conduit, and contractile strain, left atrial stiffness index, left atrial volume index (LAVI), left atrial appendage (LAA) morphology, left ventricular ejection fraction (LVEF), right atrial (RA) area, and right ventricular systolic pressure (RVSP). AF recurrence was assessed at three and six months.ResultsAt three months post-CV, LA reservoir, conduit, and contractile strain values were significantly negatively associated with AF recurrence (p < 0.001), while LASI and E/E' ratios were positively associated (p < 0.001). At six months, only contractile strain retained prognostic significance (p = 0.008). LVEF showed a positive correlation with recurrence at six months (p = 0.003), potentially reflecting the role of diastolic dysfunction.ConclusionLA strain parameters and LASI are valuable tools for predicting AF recurrence after CV, particularly in the early post-procedural period. Contractile strain may serve as a more reliable long-term predictor, emphasizing the importance of longitudinal atrial function assessment in rhythm outcome prediction. However, given the small sample size and single-center design, these results should be considered hypothesis-generating, requiring validation in larger studies.

In patients with heart failure, alterations in electrical fields generated within the myocardium have been associated with myocardial oedema which can act as a substrate for left ventricular dysfunction. Safety and efficacy of a direct microcurrent therapy using an implanted generator (C‐MIC) remain uncertain.

Newly or already diagnosed cancer might significantly influence the clinical presentation, outcome, and therapy of acute pulmonary embolism (PE).

BACKGROUND AND AIMS Adults with congenital heart disease (ACHD) knowledge regarding their heart condition is crucial for optimal long-term outcome. Previous studies from North-Western Europe showed that important gaps in ACHD knowledge still exist. This study evaluates ACHD patients' knowledge in Central and South-eastern Europe (CESEE) and aims to identify opportunities for improving life-long ACHD care and outcomes in this region. METHODS A structured survey regarding the baseline heart condition knowledge was prospectively distributed to stable ACHD patients over a one-year period (2021-2022). Patients' responses were verified by their ACHD physicians to ensure accurate background information. RESULTS Among 1650 patients (age 34.5 ±14) across 14 CESEE countries the majority 1023(62.0%) had simple congenital heart disease with at least one previous heart procedure performed 1201(72.8%); 1060(64.2%) were asymptomatic and 875(53.8%) had secondary school education. Overall, 576(34.9%) did not have basic knowledge regarding their congenital heart disease and 146(12.2%) did not have basic understanding regarding their previous heart procedure/s. Patients considered their life expectancy similar to the general population (p=0.039). Encouragingly, 962(59.5%) expressed a desire to learn more, and 929(58.1%) favoured technological integration in their care. CONCLUSIONS Significant knowledge gaps exist amongst CESEE ACHD patients regarding their heart condition. Better ACHD patient education on current health and prospects is urgently needed. The results of this study should serve for developing congenital heart disease structured transitional and educational programmes in CESEE incorporating technology for their ACHD care and education to enhance patients' health knowledge and healthy life-behaviours to positively influence their life-long prospects.

Introduction. When considering revascularization modalities, for patients with stable presentation, with appropriate coronary anatomy suitable for both PCI and CABG and low predicted surgical mortality, the recommendations are specifically focused on patients with main stem stenosis. In these cases, patients should be individually assessed according to the complexity of the anatomical disease, as determined by the anatomical SYNTAX score. In the last few years, the results of four randomized studies have been published comparing PCI with newer-generation DES and CABG in patients with left-main stenosis. The latest 2024 ESC guidelines for the management of chronic coronary syndromes recommend CABG over PCI when the anatomical SYNTAX score exceeds 22, as indicated by recent trials. The aim of this study was to examine whether the indications for CABG or PCI, as determined by the well-informed intuitive judgment of PCI operators in everyday clinical practice, align with the treatment recommendations outlined in the recently published ESC guidelines. Methods. Between January 1, 2023, and December 31, 2023, patients were recruited from the University Clinical Centre of the Republic of Srpska in Banja Luka, Bosnia and Herzegovina, utilizing the hospital information system. The study included consecutive patients diagnosed with significant unprotected left main coronary artery disease (≥50% diameter stenosis) confirmed through angiography, who did not exhibit major hemodynamic instability and received PCI at our facility. Patients were divided into two groups, based on the anatomical SYNTAX score i.e. those with SYNTAX ≤ 22 and those with SYNTAX > 22. Results. Following inclusion criteria, a total number of 38 patients were included in the analysis. The included patients had either previously diagnosed coronary artery disease or a high suspicion of coronary artery disease. The majority of the participants were male, with an average age of 65.6 years, with the youngest participant being 31 years old and the oldest 83 years old. A large majority of both sexes suffered from arterial hypertension, dyslipidemia, and type 2 diabetes. Participants in whom SYNTAX score was ≤ 22 were younger (p=0.049) and had less complex coronary artery disease i.e. fewer MEDINA 1,1,1 (p< 0.001) with less stents implanted (p=0.040). Over the course of one year of follow-up, three patients passed away, two of whom had a SYNTAX score exceeding 22. Additionally, two patients were lost to follow-up. Conclusion. The present study demonstrates that an intuitive decision-making process by experienced interventional cardiologists for choosing the optimal myocardial revascularization method for the individual patient with left main stenosis led to a discordance of the definitely chosen methods vs. the recommended method based on the SYNTAX score and ESC guidelines. This discordance between the recommended and the finally performed revascularization strategy led to a higher shortterm mortality.

Acute myocardial infarction with ST elevation (STEMI) is a disease of the elderly, rarely of people younger than 40 years, predominantly men with comorbidities. The incidence of STEMI infarction in the general population in women younger than 40 years is very low. This paper presents the case of a young woman who was admitted with a diagnosis of STEMI infarction, which was understood as SCAD after coronary angiography. Repeated invasive diagnostics with intracoronary imaging determined that it was a classic infarction with plaque rupture/erosion and a large intraluminal thrombotic mass that partially embolized with occlusion of the apical part of the anterior descending artery (LAD). She was treated during hospitalization with dual antiplatelet therapy (DAPT) using a potent P2Y12 inhibitor and low molecular weight heparin, high dose of statins. Control coronary angiography revealed insignificant narrowing of the distal part of the main trunk of the left coronary artery (LM) and the proximal segment of the LAD with almost complete resolution of the thrombus. DAPT treatment was continued without stent implantation.

Cryptogenic stroke is an ischemic stroke of unknown cause after a comprehensive diagnostic workup and accounts for a significant percentage of all strokes. This paper presents the case of a 37-year-old female patient with recurrent ischemic strokes, in whom a patent foramen ovale (PFO) was diagnosed and subsequently closed via catheter-based intervention. Despite this therapeutic procedure, further recurrences occurred. During electrophysiological evaluation and ablation of paroxysmal supraventricular tachycardia, paroxysms of atrial fibrillation were detected, leading to the initiation of anticoagulant therapy. During follow-up, the patient remained free of symptomatic recurrences. This case highlights the importance of prolonged monitoring for the detection of atrial fibrillation in patients with cryptogenic strokes, which can significantly influence therapeutic strategies and recurrence prevention.

Background/Aim. Patients classified as belonging to simplified pulmonary embolism severity index (sPESI) class 0 are considered to have low-risk pulmonary embolism (PE). Yet, certain laboratory and echocardiographic parameters not accounted for in the sPESI score might suggest a likelihood of worse outcomes in PE cases. This study seeks to determine if the prognostic value of the sPESI score in acute PE can be improved, refined, and optimised by incorporating brain natriuretic peptide (BNP) and troponin I (TnI) levels, echocardiographic parameters, or glomerular filtration rate. Methods. The study encompassed 1,201 consecutive patients diagnosed with PE, confirmed by multidetector computed tomography (MDCT). Upon admission, each patient underwent an echocardiography exam, and blood samples were taken to measure B-type natriuretic peptide (BNP), troponin I (TnI), creatinine, and other routine laboratory markers. Results. The in-hospital mortality rate was 11.5%. The patients were categorized into three groups using the three-level sPESI model: sPESI 0, sPESI 1, and sPESI ≥ 2. Statistically significant differences were found among these groups regarding mortality rates, TnI values, BNP levels, estimated glomerular filtration rate (eGFR), and the presence of right ventricular dysfunction (RVD). Cox regression analysis identified eGFR as the most reliable predictor of 30-day all-cause mortality [HR 2.24 (CI 1.264-3.969); p = 0.006] across all sPESI categories. However, incorporating TnI, BNP, or RVD did not improve risk prediction beyond the three-level sPESI model. Conclusion. Renal dysfunction at the time of admission is closely related to an elevated risk of in-hospital mortality in patients with acute PE. The three-level sPESI score offers a more accurate method for prognostic stratification in these patients.
