Patient information sheet
Condition
Contrast induced nephropathy
Intervention
Treatment group:
Patients will be given 600 mg twice daily N-acetylcysteine the day before the angiogram, and 600 mg twice on the day of the angiogram with intravenous fluids. Samples of urine and blood will be collected before the angiogram and first, second and third day post angiography.
Control group:
Patients will only get intravenous hydration as per normal protocol and will have samples taken like the treatment arm patients.
Intervention type
Drug
Phase
Not Specified
Drug names
N-acetylcysteine
Primary outcome measures
Primarily we are looking for a reduction in the elevation in Albumin/Creatinine ratio and also of other markers of renal damage in urine (retinol binding protein), using the samples collected before the angiogram and first, second and third day post angiography.
Secondary outcome measures
A reduction in the mortality and morbidity related to renal failure that may result secondary to contrast solution used in angiography; this 30-day mortality morbidity reduction will be measured on follow up in clinic normally four to six weeks post angiography.
