This study explores deep feature representations from photoplethysmography (PPG) signals for coronary artery disease (CAD) identification in 80 participants (40 with CAD). Finger PPG signals were processed using multilayer perceptron (MLP) and convolutional neural network (CNN) autoencoders, with performance assessed via 5-fold cross-validation. The CNN autoencoder model achieved the best results (recall 96.

Liver biopsy is the gold standard for diagnosing FALD, but has limitations. Magnetic resonance elastography (MRE) is a popular non-invasive method for evaluating liver stiffness and fibrosis in FALD; however, no unified view exists.

Objectives: Unstructured data, such as procedure notes, contain valuable medical information that is frequently underutilized due to the labor-intensive nature of data extraction. This study aims to develop a generative artificial intelligence (GenAI) pipeline using an open-source Large Language Model (LLM) with built-in guardrails and a retry mechanism to extract data from unstructured right heart catheterization (RHC) notes while minimizing errors, including hallucinations.
Materials And Methods: A total of 220 RHC notes were randomly selected for pipeline development and 200 for validation from the Pulmonary Vascular Disease Registry.

Background: Arterial compliance is an independent predictor of diastolic dysfunction. Invasive catheterization can accurately reflect diastolic function. However, studies on the invasive assessment of diastolic function are currently limited.

Objectives: To quantify intraoperative pulmonary arterial catheter (PAC) use during cardiac surgery and identify hospital-, anesthesiologist-, and patient-level factors associated with PAC utilization.
Design: A cross-sectional, observational study using generalized logistic mixed models to examine variations in PAC use.
Setting: Fifty-three US academic hospitals participating in the Multicenter Perioperative Outcomes Group (MPOG) national registry PARTICIPANTS: 145,343 adult patients undergoing cardiac surgery between January 1, 2016, and December 31, 2022.
