Brief summary
To determine a relatively safe contrast media volume to creatinine clearance cut-off value to avoid contrast-induced nephropathy in patients following 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.

|---|---|---|
| Contrast-Induced Nephropathy | 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
| Measure | Time frame | Description |
|---|---|---|
| An early abnormal increase in serum creatinine | 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 | 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 |
| An early abnormal increase in serum cystatin C | 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 |
