Flag, Identify, Network, Deliver (FIND) Lp(a) Machine Learning Model: Targeted Screening Enrichment of Elevated Lipoprotein(a) in Atherosclerotic Cardiovascular Disease
Authors' conclusion
One-half of adults with ASCVD flagged by FIND Lp(a) MLM had confirmed elevated Lp(a) ≥125 nmol/L. A 2.2-fold screening enrichment was observed (≥125 nmol/L model); enrichment was greater with ≥150 and ≥200 nmol/L submodels. Early performance indicators support the central role of FIND Lp(a) MLM within the ongoing FIND Lp(a) program.
