Abstract 4370204: Incidence of Myocarditis in Patients Receiving Immune Checkpoint Inhibitors
Background: Myocarditis has been recognized as an uncommon but potentially severe side effect of immune checkpoint inhibitors (ICIs). Single-center studies utilizing high-quality c...
Abstract 4369650: Fibro-proliferative Remodeling of the Endocardium in Pulmonary Vein Stenosis
Background: Pathologically elevated shear stress and cellular proliferation are known to contribute to the luminal obstruction in pulmonary vein stenosis (PVS). The initial stenosi...
Abstract 4366912: Utilizing Sequential Organ Failure Assessment score to Predict In-patient Mortality Among Patients Requiring Rapid Response Within 24 Hours of Admission
Introduction: The Sequential Organ Failure Assessment (SOFA) score is a tool to predict mortality in the medical intensive care unit (MICU). Since SOFA was developed in septic shoc...
Abstract 4369301: FB-1083 demonstrates potent efficacy in preclinical models of Heart Failure with Preserved Ejection Fraction and Pulmonary Hypertension
Introduction: Faun269g is a ligand gated ion channel discovered using the FaunaBio Platform that shows important protection from hypoxia/reperfusion damage in hibernating lined gro...
Abstract 4358805: Silent Fibrosis, Loud Signals: Early-Onset Atrial Arrhythmias as the Sentinel of Familial Restrictive Cardiomyopathy
Background: Restrictive cardiomyopathy (RCM) is a rare cardiac condition characterized by stiff and noncompliant ventricular walls, leading to impaired diastolic filling and normal...
Abstract 4363454: Single-Lead ECG AI Model Accurately Predicts Moderate-to-Severe Hyperkalemia in Multi-Hospital External Validation
Background: Hyperkalemia represents a life-threatening electrolyte disorder with substantial mortality risk, particularly in patients with chronic kidney disease (CKD) and end-stag...
