GDF15 and cervical squamous intraepithelial neoplasia: Our study showed that: a) The GDF-15 levels increased in CIN group in AMI patients underwent PCI, GDF-15 was an independent risk factor of CIN in patients with AMI underwent PCI; b) The combination of GDF-15 and serum creatinine provided a better predictive value for CIN, ACEF risk score incorporating GDF-15 showed a better performance in predicting CIN; c) Increased GDF-15 levels and CIN are independent risk factors for all-cause mortality and MACE event in short-term follow-ups.
