This provides a method to reduce cardiovascular risk in patients with a
genetic profile associated with a response to proprotein converter
subtilisin /
kexin type 9 (PCSK9) inhibitor therapy. [Solution] A method for treating a patient at risk of major cardiovascular adverse events (MACE) includes: determining the patient's polygenetic risk
score (CAD-PRS), which includes a weighted sum of multiple
gene variants associated with
coronary artery disease; identifying the patient as being at high risk of MACE if the patient has a CAD-PRS greater than a threshold CAD-PRS determined from a
reference population; and administering a PCSK9 inhibitor to the patient if the patient has been identified as being at high risk of MACE.
