In the present study, with the application of the Verify-Now P2Y12 assay for platelet function tests in clinical practice and the use of polymerase chain reaction-high performance capillary electrophoresis (PCR-HPCE) for sequencing, we found that if patients had no hypoproteinaemia or had hypertension, the SNP in rs1045642 was associated with CR (CC vs. TT: albumin ≥35, P = 0.042; hypertension, P = 0.045; C vs. T: albumin ≥35, P = 0.033; hypertension, P = 0.040). Here, P2RY12 is linked to hypertensive disorder.
