Brief Summary:
To investigate the predictive value of the contrast media volume to creatinine clearance (V/CrCl) ratio for the risk of contrast-induced nephropathy (CIN) (i.e., within 48-72 h) and to determine a relatively safe V/CrCl cut-off value to avoid CIN in patients following PCI

Condition or disease
Contrast Induced Nephropathy

Detailed Description:
contrast media volume to creatinine clearance (V/CrCl) ratios were obtained from consecutive consenting patients after unselective PCI. 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 CIN was assessed using multivariate logistic regression.

Group/Cohort
percutaneous coronary intervention
The investigators reviewed all consecutive patients who were undergoing percutaneous coronary intervention



Primary Outcome Measures :
  1. 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 :
  1. 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
