The study confirmed that baseline HCY level and RDW value in STEMI patients undergoing PCI are independently associated with increased risk for MACE outcome. Joint assessment of HCY and RDW enhances risk prediction ability, with RDW identified as a stronger predictor of unfavorable prognosis in AMI patients.
OBJECTIVE: We aimed to confirm whether serum on admission homocysteine level (HCY) and red cell distribution width (RDW) value are independent risk factors for MACE incidence in patients with STEMI myocardial infarction treated by percutaneous coronary intervention (PCI), as well as the possibility of their joint assessment in order to enhance the risk stratification for major adverse cardiac events (MACE). PATIENTS AND METHODS: A total of 80 patients with acute myocardial infarction (AMI) were included in the study and tested for blood HCY and RDW values. Patients were followed up for six months after discharge and evaluated for MACE occurrence. RESULTS: The RDW value was significantly associated with HCY level (r=0.267, p=0.026). Univariate logistic regression analysis identified both the RDW and HCY as independent predictors of MACE (OR 2.179; CI 95% 1.250 to 3.797; p=0.006 and OR 1.108; CI 95% 1.013 to 1.213; p=0.025, respectively), naming RDW as a stronger predictor of unfavorable prognosis in AMI patients. Addition of HCY to RDW value in receiver operating characteristic (ROC) curve analysis increased the area under the curve (AUC) from 0.705 to 0.730 (p=0.007), while risk prediction model, which also included traditional risk factors, increased AUC up to 0.806, implying this model as good predictor of MACE both in low-risk and high-risk STEMI patients. CONCLUSIONS: A high baseline HCY level and RDW value in patients with STEMI undergoing PCI is independently associated with increased risk for MACE outcome. Their joint assessment increases risk prediction ability.
