Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The intention of this trial is to investigate, if a short-term calorie restriction before contrast agent administration can prevent contrast induced nephropathy.;Primary end point(s): Analysis of the increase of serum creatinine 48h after the onset of coronary intervention (contrast agent exposition).;Timepoint(s) of evaluation of this end point: 48 hours after intervention;Secondary Objective: Analysis of the increase of serum creatinine 24h after the onset of coronary intervention (contrast agent exposition); Neutrophil gelatinase-associated lipocalin (NGAL in µg/l) in urine 24h after the onset of coronary intervention (contrast agent exposition); Cystatin C in plasma (mg/l) 24h after the onset of coronary intervention (contrast agent exposition) | — |
