Heart failure & cardiomyopathiesDiagnostic or prognostic study
Evaluation of diastolic function: machine learning improves classification of left ventricular filling pressure
- multicentre study
- nested cross-validation
- echocardiography simultaneously with, or within 24 h of, heart catheterization
Authors' conclusion
ML can improve classification of LVFP, particularly with a higher feasibility. The study unveiled less used parameters as some of the most valuable for evaluating LVFP.
Study context
- Population
- Patients undergoing echocardiography and heart catheterization
- Participants
