CHA2DS2-VASC-HS SCORE AS A PREDICTOR OF SEVERITY OF CORONARY LESIONS, AND COMPLICATIONS OF PRIMARY PERCUTANEOUS CORONARY INTERVENTION FOR STEMI PATIENTS
Objective: To study if CHA2DS2-VASc-HS score can predict severity of coronarylesions, contrast induced nephropathy and new onset transient ischemic attack(TIA) or stroke during hospital admission in patients without atrial fibrillation(AFib) presented by STEMI and treated by primary PCI.
Methodology: We performed a cross-sectional study on STEMI patients treatedby primary PCI in cardiology department Tanta University hospital, Egyptbetween January 2016 and January 2018. CHA2DS2-VASc-HS score, Mahranrisk score and SYNTAX score were calculated for all patients excluding patientspresented with Afib. Occurrence of CIN, new-onset TIA or stroke and death wasnoted for all patients.
Results: About 179 STEMI patients were included. We found that CHA2DS2-VASc-HS score > 4 is associated with higher incidence of CIN P value (0.001),new-onset stroke or TIA P value (0.003) and death (0,001). Also Score from (0-2) has less incidence of occurrence of theses complication and the score > 4has higher incidence of complex coronary lesions P value (0.001).
Conclusion: CHA2DS2-VASc-HS score can be used as a good predictor ofcomplexity of coronary anatomy, in hospital mortality (CIN, new-onset TIA orStroke and death) in patients presented with STEMI.
