Primary Outcome Measures:
  • Contrast-Induced Nephropathy [ Time Frame: 48-72 h ]
    Contrast-Induced Nephropathy was defined as an increase in serum creatinine of more than 0.5 mg/dl from the baseline within 48-72 h of contrast exposure


Secondary Outcome Measures:
  • An early abnormal increase in serum creatinine [ Time Frame: 24h ]
    An early abnormal increase in serum creatinine defined as an increase in serum creatinine of more than 0.5 mg/dl from the baseline within 24h of contrast exposure

  • Major adverse clinical events [ Time Frame: 1 year ]
    Major adverse clinical events: death, requiring renal replacement therapy, 2nd myocardial infarction,target revascularization,acute heart failure, mechanical ventilation,2nd angina,tachyarrhythmia,hypotension,intra-aortic balloon pump and stroke

  • Major adverse clinical events [ Time Frame: 1month ]
    Major adverse clinical events: death, requiring renal replacement therapy, 2nd myocardial infarction,target revascularization,acute heart failure, mechanical ventilation,2nd angina,tachyarrhythmia,hypotension,intra-aortic balloon pump and stroke

  • An early abnormal increase in serum cystatin C [ Time Frame: 24h ]
    An early abnormal increase in serum cystatin C was defined as an increase more than 10% from the baseline within 24h of contrast exposure

Groups/Cohorts
coronary angiography
The investigators reviewed all consecutive patients who were undergoing coronary angiography

Detailed Description:
Contrast media volume to creatinine clearance (V/CrCl) ratios were obtained from consecutive consenting patients after coronary angiography. Receiver-operator characteristic (ROC) curves were used to identify the optimal sensitivity for the observed range of V/CrCl. The predictive value of V/CrCl for the risk of contrast-induced nephropathy was assessed using multivariate logistic regression.Subgroup analysis was performed on patients with creatinine clearance < 60 ml/min,diabetes,emergent angiography.
