Specifically, each patient contains 105 features, including demographics (e.g. age and gender), vital signs (e.g. blood pressure and heart rate), lab tests (e.g. NT-proBNP and CTnT), echocardiography (e.g. ejection fraction and QRS interval), comorbidities (e.g. diabetes and renal insufficiency), length of stay (LOS) and medications (e.g. ACEI/ARB, beta blocker and MRA). Here, NPPB is linked to Renal insufficiency.
