Heart failure & cardiomyopathies

Impact of Case and Control Selection on Training Artificial Intelligence Screening of Cardiac Amyloidosis

JACC AdvPublished Diagnostic accuracy study

Authors' conclusion

Models performed similarly in population screening, regardless of stringency of cases used during training, showing that institutions without dedicated amyloid clinics can train meaningful models on less curated CA cases.

Study context

Population
Patients with electrocardiogram (ECGs) (∼1.3 million ECGs) screened for cardiac amyloidosis; Cedars-Sinai general patient population test cohort
Participants
341,989 patients∼1.3 million ECGs
Comparison
ECG-based AI models trained with different case and control definitions for cardiac amyloidosis (CA) screening
Outcome
AUC of ECG-based AI models for CA screening
