Abstract The coronavirus disease 2019 (COVID-19) can result in a hyperinflammatory state, leading to acute respiratory distress syndrome (ARDS), myocardial injury, and thrombotic complications, among other sequelae. Statins, which are known have anti-inflammatory antithrombotic properties, been studied the setting of viral infections, but their benefit has not assessed COVID-19. This is retrospective analysis patients admitted with COVID-19 from February 1 st through May 12 th , 2020 study...

Abstract The primary practice of healthcare artificial intelligence (AI) starts with model development, often using state-of-the-art AI, retrospectively evaluated metrics lifted from the AI literature like AUROC and DICE score. However, good performance on these may not translate to improved clinical outcomes. Instead, we argue for a better development pipeline constructed by working backward end goal positively impacting clinically relevant outcomes leading considerations causality in...

Abstract The electrocardiogram (ECG) is the most frequently performed cardiovascular diagnostic test, but it unclear how much information resting ECGs contain about long term risk. Here we report that a deep convolutional neural network can accurately predict long-term risk of mortality and disease based on ECG alone. Using large dataset 12-lead collected at Stanford University Medical Center, developed SEER, Estimator Electrocardiogram Risk. SEER predicts 5-year with an area under receiver...

Abstract Background and Aims Early identification of cardiac structural abnormalities indicative heart failure is crucial to improving patient outcomes. Chest X-rays (CXRs) are routinely conducted on a broad population patients, presenting an opportunity build scalable screening tools for Stage B or worse with deep learning methods. In this study, model was developed identify severe left ventricular hypertrophy (SLVH) dilated ventricle (DLV) using CXRs. Methods A total 71 589 unique CXRs...

BACKGROUND: Artificial intelligence, particularly deep learning (DL), has immense potential to improve the interpretation of transthoracic echocardiography (TTE). Mitral regurgitation (MR) is most common valvular heart disease and presents unique challenges for DL, including integration multiple video-level assessments into a final study-level classification. METHODS: A novel DL system was developed intake complete TTEs, identify color MR Doppler videos, determine severity on 4-step ordinal...

The 12-lead electrocardiogram (ECG) remains a cornerstone of cardiac diagnostics, yet existing artificial intelligence (AI) solutions for automated interpretation often lack generalizability, remain closed-source, and are primarily trained using supervised learning, limiting their adaptability across diverse clinical settings. To address these challenges, we developed compared two open-source foundational ECG models: DeepECG-SSL, self-supervised learning model, DeepECG-SL, model. Both models...
