P2RY12 and Schnyder corneal dystrophy: However, patients prescribed P2Y12 antagonists (HR = 0.285, 95% CI: 0.135–0.603, p < 0.001), those with a GFR >  60 ml/min (HR = 0.314, 95% CI: 0.158–0.624, p < 0.001), and those with a higher ejection fraction (HR = 0.962, 95% CI: 0.939–0.986, p = 0.002) were less likely to experience SCD following CABG.
