Background: Patients with chronic kidney disease (CKD) have an elevated risk of adverse cardiovascular events. However, the impact of different stages of CKD on the prognosis of patients with atrial fibrillation (AF) after percutaneous coronary intervention (PCI) remains uncertain.
Methods: This multicenter registry included 902 patients with AF undergoing PCI. Patients were divided into 3 groups based on renal function: normal [estimated glomerular filtration rate (eGFR) ≥ 60 mL/min/1.73m2], early CKD (30 ≤ eGFR <60 mL/min/1.73m2), and advanced CKD (eGFR <30 mL/min/1.73m2 or patients on hemodialysis). The primary endpoint was net adverse clinical events (NACE) within 1 year after PCI, a composite of all-cause death, myocardial infarction (MI), ischemic stroke, and major bleeding (Bleeding Academic Research Consortium type 3 or 5) events.
Results: Of the 902 patients, 338 (37.5 %), 438 (48.5 %), and 126 (14.0 %) were grouped as normal, early CKD, and advanced CKD. Within the one-year follow-up period, 142 (15.7 %) patients experienced NACE after PCI. The progression of CKD was associated with increased NACE rates, mainly driven by an increased risk of all-cause death. There were no significant differences in the rates of MI, ischemic stroke, and major bleeding events among the three groups.
Conclusions: Advanced CKD was significantly associated with a higher incidence of NACE compared with early CKD or normal renal function in patients with AF after PCI.

The role of point-of-care ultrasound (POCUS) in diagnosing acute heart failure is not fully established. We evaluated the diagnostic accuracy of cardiac, lung, and inferior vena cava (IVC) POCUS, individually and combined, in the emergency department (ED).
We systematically searched PubMed, Embase, Web of Science, and Google Scholar for English-language studies published from inception to November 2024. Statistical analyses were conducted using STATA 16, and study quality was assessed with the QUADAS-2 tool.
Fifteen studies involving 2751 dyspneic patients in the ED were included. Lung ultrasound demonstrated sensitivities of 72 % for B-lines ≥10, 79 % for bilateral B-pattern in two or more zones, and 100 % for pleural effusion, with specificities of 86 %, 82 %, and 75 %, respectively. Cardiac ultrasound revealed sensitivities of 70 % for the E/A ratio, 100 % for the E/e′ ratio, and 63–82 % for varying left ventricular ejection fraction (LVEF) thresholds (<40 %, <45 %, <50 %), with specificities ranging from 76 % to 88 %.
Plethoric IVC demonstrated a sensitivity of 100 % and a specificity of 25 %. The IVC collapsibility index (IVC-CI) <20 % and <50 % yielded sensitivities of 43 % and 83 % and specificities of 90 % and 81 %, respectively. Multiorgan ultrasound combining lung and cardiac findings achieved overall sensitivity of 78 % and specificity of 96 %. Combining bilateral B-pattern in two or more zones, MAPSE, E/A, and E/e′ yielded 96 % sensitivity and 93 % specificity. The combination of LVEF and B-lines demonstrated 61 % sensitivity and 96 % specificity, while LVEF and bilateral B-pattern in two or more zones showed 70 % sensitivity and 93 % specificity. LVEF and pleural effusion showed a sensitivity of 91 % and a specificity of 99 %. Adding IVC to the combined lung and cardiac approach resulted in a specificity of 99 % but reduced sensitivity to 54 %. Conclusively, the lung, cardiac, and IVC ultrasounds, individually or combined, demonstrated consistently high specificity and moderately high sensitivity.

Cardiovascular disease (CVD) is the world's major concern affecting the heart, blood arteries, and the blood that flows through and between them, making it a significant obstacle to contemporary healthcare practices. Approximately one in three individuals has a CVD, and many of them have several, overlapping diseases that might eventually result in catastrophic events such as a heart attack or stroke. The previous century opened the door for progress of life-saving drugs and treatment modalities. Recent developments in nanomaterials provide novel approaches for the treatment of CVD. Due to their unique properties, which include increased target specificity, sensitivity, and both active and passive targeting of cardiac tissues, the use of nanoparticles as carriers has received a lot of attention in the field of cardiology. Drug delivery using heart-targeted nanocarriers is a safe, efficient method of treating heart-related conditions such as hypertension, atherosclerosis, and myocardial infarction. Here, we highlight significant clinical opportunities in the quickly emerging field of CVD nanomedicine. This review concentrates on the use of nanoparticle-based therapeutics in CVD and provides a key take away regarding the use of metal, lipid, and polymer-based nanoparticle in CVD treatment. In this review, we emphasize recent advances in the use of nanomedicine to treat CVD and the therapeutic potential of drug delivery via nanoparticles in clinical prospects.

The ring finger protein 213 (RNF213) gene, identified in 2011 as a susceptibility gene for moyamoya disease (MMD), has since been recognized as a key factor in a broader spectrum of vascular disorders. The p.R4810K mutation in RNF213 is particularly common among Japanese MMD patients, although a smaller percentage of healthy individuals also carry the mutation, indicating that environmental factors, alongside genetic predisposition, likely influence disease onset. RNF213, a large E3 ubiquitin ligase, plays essential roles in vascular homeostasis, immune response, and endoplasmic reticulum stress reaction. Its mutation disrupts normal angiogenesis, contributing to abnormal vascular remodeling in conditions such as pulmonary hypertension and coronary artery disease. This review examines the multifaceted role of RNF213 and its p.R4810K mutation in the pathogenesis of MMD and other vascular conditions, collectively referred to as RNF213-associated vascular diseases.
While research has begun to clarify the mutation's effects on angiogenesis and the involved pathways, the roles of RNF213 and its mutation in vascular integrity remain unclear. This comprehensive overview underscores the complex interaction between genetic and environmental factors in RNF213-related vascular diseases and calls for further research to elucidate these mechanisms and develop targeted therapeutic interventions.

Radiofrequency catheter ablation (RFCA) is a common treatment option for ventricular arrhythmias (VA). Risks of RFA for VA include emboli and bleeding complications. In contrast to atrial fibrillation ablation procedures, for which anticoagulation therapy is relatively well standardized, peri-procedural antithrombotic therapy practices for RFCA of VA vary among laboratories and remains an area of investigation. This summary focuses on the current evidence-based antithrombotic therapies of RFCA for VA, with a particular emphasis on two recent major studies.

Implantable cardioverter defibrillator (ICD) implantation is an established treatment that reduces the risk of sudden cardiac death; however, patients with ICD have been shown to be anxious. This study aimed to identify the characteristics of anxiety about returning to work after ICD implantation and to explore reemployment support.
Methods
Data from 56,002 patients who worked before admission to the cardiology department were analyzed using the Inpatient Clinico-Occupational Database of the Rosai Hospital Group (2011−2022). The patients were further categorized into two groups depending on whether ICD surgery was performed during hospitalization. Among patients who had undergone ICD surgery, multivariable logistic regression models were used to estimate the relationships between the prehospitalization occupational data, clinical data, and anxiety about returning to work.
Results
The ICD group had a higher rate of anxiety about returning to work than the non-ICD group (26.2 % vs. 16.1 %; p < 0.001). In the ICD group, younger age at discharge, female sex, self-employed, and longer working hours per day were independently associated with anxiety about returning to work. Among patients experiencing anxiety about returning to work, compared with the non-ICD group, the ICD group had a lower rate of anxiety about workplace understanding (17.9 % vs. 35.0 %; p = 0.008); but a higher rate of anxiety about workplace life (37.5 % vs. 18.3 %; p < 0.001).
Conclusions
The ICD group had a higher rate of anxiety about returning to work. This study suggests that interventions for anxiety about returning to work, especially regarding life in the workplace, are important for working populations with ICDs.
背景：植入式心律转复除颤器（ICD）植入术是一种降低心源性猝死风险的成熟治疗方法；然而，ICD患者表现出焦虑。本研究旨在了解ICD植入后重返工作岗位的焦虑特征，并探讨再就业支持。方法：使用罗赛医院集团住院临床职业数据库（2011-2022）对56002例入院前在心内科工作的患者数据进行分析。根据住院期间是否进行ICD手术，将患者进一步分为两组。在接受ICD手术的患者中，使用多变量logistic回归模型来估计住院前职业数据、临床数据和重返工作焦虑之间的关系。结果：ICD组对重返工作的焦虑率高于非ICD组(26.2 % vs. 16.1 %；p 结论：ICD组对重返工作岗位的焦虑率更高。这项研究表明，对重返工作岗位的焦虑进行干预，特别是对工作场所的生活，对患有icd的工作人群很重要。

Although perfusion imaging is effective for evaluating relative myocardial blood flow (MBF) distribution, it has a well-known limitation in single photon emission computed tomography (SPECT): it often underestimates ischemia, particularly in patients with three-vessel coronary artery disease or left main trunk disease. In such cases, global reductions in MBF may not create significant perfusion defects, complicating the accurate detection of ischemia. In contrast, positron emission tomography (PET) has long offered absolute MBF quantification through dynamic imaging, allowing for a more precise assessment of coronary artery disease and microvascular dysfunction. By integrating absolute MBF quantification with perfusion imaging, PET has significantly improved diagnostic accuracy in ischemia evaluation.
Relative to PET, traditional SPECT has struggled to achieve comparable MBF quantification due to its lower sensitivity and spatial resolution. However, recent advancements in semiconductor-based detector technology have enabled SPECT to approximate PET's quantification accuracy. Emerging studies indicate that modern SPECT systems can now deliver absolute MBF values with enhanced reliability, opening new possibilities for clinical application.
Despite PET's superior quantification capability, its availability remains confined to specialized facilities, limiting its broader clinical use. In this context, the implementation of SPECT to quantify MBF presents a promising avenue for expanding access to more accurate ischemia assessment. Enhancing the diagnostic precision of SPECT could improve patient stratification and treatment planning, particularly in environments where PET is not readily available.
This review summarizes recent advancements in MBF quantification using SPECT, discusses its clinical implications, and explores the prospects for its integration into routine cardiovascular imaging.

Frailty has increasingly been recognized as an important factor influencing the prognosis of older patients with heart failure (HF). While previous studies have primarily focused on physical frailty, the need for comprehensive frailty assessments, including assessments of cognitive and social aspects, has been emphasized for effective HF management. Although the importance of multidimensional frailty assessment has been highlighted in the past, specific indicators for defining multidimensional frailty and its relationship with prognosis have not been clearly established to date. The FRAGILE-HF cohort study is a multicenter prospective cohort study that investigates the prevalence, overlap, and prognostic impact of multidimensional frailty in older patients with HF. The primary objective of this project was to address issues related to multidimensional frailty in older patients with HF. Additionally, this study provides extensive foundational data not only on frailty but also on sarcopenia and cachexia, which are commonly observed in older patients with HF. This review summarizes the current understanding of physical and non-physical frailty, sarcopenia, and cachexia in patients with HF, with a focus on insights from the FRAGILE-HF registry.

This study evaluated the safety of sacubitril/valsartan for up to 52 weeks in Japanese patients with chronic heart failure (CHF) in real-world settings.
Methods
This was an uncontrolled, multicenter, observational study conducted at 120 sites in Japan. Adult patients on standard of care for CHF and newly initiated on sacubitril/valsartan were included. The primary outcome was the exposure-adjusted incidence rate (EAIR: patients/100 patient-years) of adverse drug reactions (ADRs) and adverse events of interest (related to hypotension, hyperkalemia, renal impairment, and dehydration). The impact of patient risk factors on ADRs and clinical outcomes (EAIR of the composite endpoint [cardiovascular (CV) death or first hospitalization due to heart failure], and its components) were also assessed.
Results
Overall, 682 patients (median age: 78.0 years, male: 61.4 %, age 75 years: 61.9 %) were assessed. Sacubitril/valsartan was typically initiated at 50 mg twice daily and up-titrated to 100 mg or 200 mg sequentially at 2- to 4-week intervals. Dose adjustments were made in 57.2 % of patients. EAIRs of ADRs related to hypotension, hyperkalemia, renal impairment, and dehydration were 7.776, 0.606, 0.913, and 0.151, respectively. The incidence of ADRs was 9.7 %, with hypotension (4.7 %) and decreased blood pressure (1.8 %) being the most common ADRs. Patients with systolic blood pressure (SBP) of ≤120 mmHg at sacubitril/valsartan initiation had a higher risk of ADRs than those in other SBP groups. EAIRs for composite endpoints, CV death, and first hospitalization for heart failure were 9.404, 2.269, and 8.150, respectively.
Conclusions
This study did not show notable differences from the known safety profile of sacubitril/valsartan, and no new safety concerns were identified in Japanese patients with CHF. The EAIR of the composite endpoint of CV death or first hospitalization due to heart failure was lower than that in patients enrolled in clinical studies at the time of approval.
