Heart failure & cardiomyopathies

INSIGHT Model: Explainable Artificial Intelligence for Real-World EHR-Based Screening of Transthyretin Amyloidosis Cardiomyopathy

JACC AdvPublished explainable artificial intelligence screening tool

Authors' conclusion

In an unselected HF population with 1% prevalence of suspected ATTR-CM, INSIGHT-CM identified patients among whom 1 in 5 fit the pattern for suspected ATTR-CM, offering meaningful opportunities to improve timely diagnosis and treatment.
