Summary

This study aims to evaluate whether the serum levels of Cystatin C (CysC) can be used as early biomarkers for the identification of patients who are prone to AKI after cardiac interventional surgeries as primary percutaneous coronary intervention (PCI)

Detailed description

Acute Kidney Injury (AKI) is defined as an absolute increase in serum creatinine ≥0.3 mg/dl (≥26.4 μmol/l), a percentage increase in serum creatinine ≥50% (1.5-fold from baseline), or a reduction in urine output (documented oliguria \< 0.5 ml/kg/hour for \> 6 hours) Serum creatinine which is considered the gold standard currently for diagnosis of AKI remains unchanged until 50% of kidney function falls down. It is affected by non-specific factors like diet, age, dehydration, muscle mass, gender, and drugs There were evidences of the association between AKI and acute coronary syndrome (ACS); First, AKI detection may be missed by cardiologists. Physicians tend to disregard mild or transient serum creatinine elevation during hospital stay for ACS, and they often attribute small serum creatinine increases to laboratory variations. Cystatin C (CysC), a cystatin protease inhibitor, is less affected by non-specific factors. When GFR decreases, CysC begins to increase. CysC was recommended to be measured in addition to creatinine in GFR estimation.
