Tc-HFAPi SPECT imaging predicts left ventricular remodeling after acute myocardial infarction.

Background: Despite improved treatments for acute myocardial infarction (AMI), myocardial fibrosis remains a key driver of adverse left ventricular (LV) remodeling and increased mortality. Fibroblast activation and proliferation significantly contribute to this process by enhancing cardiac fibrosis, which can lead to detrimental changes in LV structure. This study evaluates the effectiveness of Tc-labeled fibroblast activation protein inhibitor (Tc-HFAPi) SPECT imaging in predicting LV remodeling over 12 months in post-AMI patients.

Primary mature teratoma of the left adrenal gland: a case report.

Teratoma are germ cell tumors, most frequently arising in and retroperitoneal teratomas are rare, especially adrenal teratomas. Only a few case reports have been documented in the literature so far. We report the case of a 52-year-old asymptomatic male patient who had an incidental finding of a left adrenal teratoma during an abdominal computed tomography scan; due to the large size of the tumor, he underwent laparoscopic left adrenalectomy, and histopathological examination revealed a mature teratoma of the left adrenal gland, Patient recovering well after surgery and had no recurrence after 6 months of postoperative follow-up.

Ectopic adrenocorticotropic hormone-secreting pheochromocytoma with severe metabolic disturbances: A case report.

Introduction: The occurrence of hypercortisolism resulting from adrenocorticotropic hormone (ACTH)-secreting pheochromocytoma is exceedingly uncommon, with limited documented instances thus far.

Presentation Of Case: We present a case of ectopic ACTH-secreting pheochromocytoma in a patient who suffered from severe metabolic disorders. Our clinical case outlines the diagnostic history, preoperative correction of the patient's metabolic disturbances and surgical strategy for management of a rare ectopic ACTH producing pheochromocytoma.

Implications of bleeding on subsequent cardiovascular events in patients with atrial fibrillation after acute coronary syndrome or PCI.

Introduction: The association between bleeding and subsequent major adverse cardiac and cerebrovascular events (MACCE) remains poorly characterized. We aimed to evaluate the impact of hemorrhagic events in patients with atrial fibrillation (AF) and acute coronary syndrome (ACS) or undergoing percutaneous coronary intervention (PCI).

Materials And Methods: A total of 1877 consecutive patients with AF and ACS or undergoing PCI were prospectively recruited.

Clinical Application of CHADS-VASc versus GRACE Scores for Assessing the Risk of Long-term Ischemic Events in Atrial Fibrillation and Acute Coronary Syndrome or PCI.

Background: Early risk stratification of patients with atrial fibrillation (AF) and acute coronary syndrome (ACS) or undergoing percutaneous coronary intervention (PCI) has relevant implication for individualized management strategies. The -VASc and GRACE ACS risk model are well-established risk stratification systems. We aimed to assess their prognostic performance in AF patients with ACS or PCI.

Evolving Antithrombotic Treatment Patterns for Patients With Nonvalvular Atrial Fibrillation and Acute Coronary Syndrome or Underwent Percutaneous Coronary Intervention in China: A Cross-Sectional Study.

Objective: Antithrombotic therapy in patients with nonvalvular atrial fibrillation (NVAF) concomitant with the acute coronary syndrome (ACS) or underwent percutaneous coronary intervention (PCI) is challenging and has evolved in recent years. However, real-world data on this issue about antithrombotic regimens at discharge and its evolving trend were relatively scarce, especially in China.

Methods: A total of 2,182 patients with NVAF and ACS/PCI were enrolled from 2017 to 2019.

[The predictive value of the CHADS-VASc score for in-hospital outcomes in patients with acute myocardial infarction: China PEACE-retrospective acute myocardial infarction study].

This study aimed to evaluate the predictive value of the CHADS-VASc score for in-hospital outcomes of patients with acute myocardial infarction (AMI). Data of 23 728 patients from the China patient-centered Evaluative Assessment of cardiac Events (China PEACE)Retrospective Acute Myocardial Infarction Study were analyzed retrospectively. The patients were categorized into 3 groups according to the CHADS-VASc scores: the low score group (score 1-3), the middle score group (score 4-6) and the high score group (score 7-9).

The incidence and location of epicardial connections in the era of contact force guided ablation for pulmonary vein isolation.

Background: The effects of epicardial connections (ECs) involving pulmonary veins (PVs) in atrial fibrillation (AF) ablation have been revealed recently. However, no systematic approaches to identify and ablate the ECs were established.

Methods: Patients with AF undergoing radiofrequency (RF) catheter ablation were retrospectively analyzed.

Efficiency, Safety, and Efficacy of High-Power Short-Duration Radiofrequency Ablation in Patients with Atrial Fibrillation.

Pulmonary vein isolation (PVI) is the cornerstone therapy of atrial fibrillation (AF). Radiofrequency catheter ablation (RFCA) is performed using a point-by-point method to achieve durable PVI. However, this procedure remains complex and time-consuming, and the long-term clinical outcomes are still not satisfactory.

Electrocatalytic oxygen reduction reaction activity of KOH etched carbon films as metal-free cathodic catalysts for fuel cells.

In this article, surface-modified graphite materials as cathodic catalysts are prepared by hot filament chemical vapor deposition and then chemically etched by KOH solution. Surface morphology, elemental composition, microstructure and surface chemical state of the modified graphite films are characterized by scanning electron microscopy, transmission electron microscopy, energy dispersive spectroscopy, Raman spectroscopy and X-ray photoelectron spectroscopy techniques. Results indicate that the surface of the pristine graphite can be refined to effectively improve the surface area by etching using the KOH solution with a moderate concentration.

Predictive value of unipolar and bipolar electrograms in idiopathic outflow tract ventricular arrhythmia mapping and ablation.

Introduction: Radiofrequency catheter ablation is an effective therapy for focal idiopathic outflow tract ventricular arrhythmia (OTVA). However, visual inspection of the unipolar electrogram (EGM) QS morphology is subjective with a poor specificity for predicting successful ablation sites. This study aims to evaluate the predictive value of unipolar and bipolar EGMs in OTVA mapping and ablation.
