Predicting outcomes in patients with aortic stenosis using machine learning: the Aortic Stenosis Risk (ASteRisk) score

Open Heart

Objective To use echocardiographic and clinical features to develop an explainable clinical risk prediction model in patients with aortic stenosis (AS), including those with low-gradient AS (LGAS), using machine learning (ML). Methods In 1130 patients with moderate or severe AS, we used bootstrap lasso regression (BLR), an ML method, to identify echocardiographic and clinical features important for predicting the combined outcome of all-cause mortality or aortic valve replacement (AVR) within 5

Guidelines for the development, evaluation, and implementation of AI-based prediction models in healthcare

Cardiomatics

Due to the continuous development of medicine and the huge amount of clinical data collected while practicing it, there is an urgent need to optimize the working time of clinicians. One way to do this is to analyze clinical data using machine learning and artificial intelligence (AI) based on predictive models. These models predict the presence or future occurrence of specific outcomes (e.g., a specific condition or disease) with specific inputs (e.g., certain patient characteristics or medical

Hepatocyte growth factor is associated with greater risk of extracoronary calcification: results from the multiethnic study of atherosclerosis

Open Heart

Background Hepatocyte growth factor (HGF) is a biomarker with potential for use in the diagnosis, treatment and prognostication of cardiovascular disease (CVD). Elevated HGF is associated with calcification in the coronary arteries. However, knowledge is limited on the role HGF may play in extracoronary calcification (ECC). This study examined whether HGF is associated with ECC in the aortic valve (AVC), mitral annulus (MAC), ascending thoracic aorta and descending thoracic aortic (DTAC).
