BACKGROUND: The cortical vessel signs (CVSs) on susceptibility-weighted images (SWIs) have been reported in patients with hyperacute ischemic stroke. We evaluated the change of this susceptibility sign on the immediate SWI after full recanalization and its clinical implications. METHODS: Nineteen hyperacute ischemic stroke patients who had acute large artery occlusion and underwent post-recanalization SWI were enrolled in this study. The patients had ICA (internal carotid artery, 2 cases), M1 (M

We showed that when serum CRP level is high, IRI results in multiple miRNA profile changes not only in ischemic areas but also in non-ischemic myocardium. Our results may provide a strong basis for studying the role of CRP and miRNAs in ischemic heart disease.

OBJECTIVE: The molecular mechanisms of the degeneration of the aortic wall in abdominal aortic aneurysm (AAA) are poorly understood. The monomeric form of C-reactive protein (mCRP) is deposited in damaged cardiovascular organs and aggravates the prognosis; however, it is unknown whether mCRP is deposited in the degenerated aorta of abdominal aortic aneurysm (AAA). We investigated whether mCRP is deposited in AAA and examined the associated pathogenic signaling pathways. METHODS: Twenty-four case

This study aimed to investigate the clinical implication of surgical resection for the malignancies of heart and great vessels. Between January 2001 and May 2011, a retrospective review of the results in 12 patients was conducted. There were 6 patients with primary cardiac tumor including leiomyosarcoma, angiosarcoma, undifferentiated type sarcoma and malignant fibrous histiocytoma. The remaining 6 patients had the metastatic tumors or adjacent invasion to the heart and great vessels. Six of sev

OBJECTIVES: We evaluated the effect of monomeric C-reactive protein (CRP) deposition on areas at risk (AAR) of myocardium with ischaemia-reperfusion injury. METHODS: Myocardial ischaemia-reperfusion injury model was produced by ligation of the left anterior descending coronary artery for 45 min followed by 45 min of reperfusion using female Sprague-Dawley rats. Tissue from non-ischaemic areas, areas at risk and infarct areas determined by Evans blue and 2,3,5-triphenyltetrazolium chloride staini

ABSTRACT Background Abdominal aortic aneurysm (AAA) is a potentially lethal condition that often remains asymptomatic until it ruptures. Recent research suggests that immune-inflammatory processes are associated with AAA development, yet the exact mechanisms remain unclear. Serum C-reactive protein (CRP) serves as a prognostic marker for AAA and various cardiovascular diseases. When CRP accumulates in damaged tissues, it transforms into a monomeric form, exacerbating tissue damage. Our previous

Heart failure (HF), particularly acute decompensated heart failure (ADHF), remains a significant health challenge, with limited long‐term therapeutic options to alleviate congestion and improve cardiac function. Pharmacological treatments focus on reducing congestion, but many patients are discharged with persistent symptoms, leading to poor outcomes. Current device‐based solutions, such as balloon catheters, offer some relief from fluid overload but require hospitalization, a driveline, and dir

Abdominal aortic aneurysm (AAA) progression carries a significant rupture risk, demanding accurate prediction models beyond traditional methods that rely on limited clinical parameters and often overlook complex factor interplay. We aimed to enhance prediction by developing and validating an end-to-end multi-modal deep learning (DL) model that integrates features extracted using ResNet from computed tomography (CT) images, geometric features derived from radiomics based on CT annotations, and cl

Background: We present our 12-year experience of pulmonary thromboendarterectomy in patients with chronic thromboembolic pulmonary hypertension. Materials and Methods: Between January 1999 and March 2011, 16 patients underwent pulmonary thromboendarterectomy. Eleven patients (69%) were classified as functional class III or IV based on the New York Heart Association (NYHA) classification. Seven patients had a history of inferior vena cava filter insertion, and 5 patients showed coagulation disord

Background: We investigated the effects of C-reactive protein (CRP) deposition on the vessel walls in abdominal aortic aneurysm (AAA) by analyzing spatially resolved changes in gene expression. Our aim was to elucidate the pathways that contribute to disease progression. Methods: AAA specimens from surgically resected formalin-fixed paraffin-embedded tissues were categorized into the AAA-high CRP [serum CRP ≥ 0.1 mg/dL, diffuse and strong immunohistochemistry (IHC); n = 7 (12 cores)] and AAA-low
