Filter by:The REduction of rIsk for Contrast-Induced Nephropathy (REICIN) study is the largest prospective multicenter data base for CIN flowing coronary angiography (CAG) or percutaneous coronary intervention (PCI). The REICIN study has the potential to characterize contemporary CIN incidence, modified risk factors and prognosis, so that to identify strategiaes to reduce risk of CIN following CAG/PCI.
To determine a relatively safe contrast media volume to creatinine clearance cut-off value to avoid contrast-induced nephropathy in patients following coronary angiography
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
OBJECTIVE: To evaluate the efficacy of prevention of contrast induced nephropathy in patients with ST segment elevation myocardial infarction treated with primary percutaneous coronary intervention. DESIGN: Prospective study. SETTING: Three-center study Acute kidney injury was defined as a rise in creatinine >25% from baseline Serum creatinine will be measured at baseline and each day for the following 3 days and at 30 days. Patients will be randomised to: 1. Standard treatment 2. Standard treatment + acetylcystein for 2 days 3. Standard treatment + Sodium bicarbonate 500 ml / followed by 100 ml/h for 5 hours 4. Standard treatment + acetylcystein for 2 days + Sodium bicarbonate 500 ml / followed by 100 ml/h for 5 hours
The investigators will study 2 separate groups: - Cardiology patients undergoing invasive coronary angiography +/- PCI (Percutaneous coronary intervention). - Patients undergoing CT examination with contrast medium. All patients will receive intravenous (I.V) hydration for 8-12h before and 36 to 48 h after angiography with 0.45% saline 100ml/h. All patients will receive oral N-acetyl cysteine 1200 mg twice daily, a day before, on the day of the angiography and for another 48 hours. In addition, patients will be assigned to receive oral pentoxyphylline (P group) or placebo (C - control group) tablets 3 times a day one day before, on the day of the procedure and for another 48 hours. Baseline Serum Creatinine (S.Cr) levels in will be taken before angiography and two days after angiography. Radio-contrast nephropathy is defined, in this study, as increase in serum ≥ 25 % of baseline after injection of the radio-contrast agent. Pentoxyfylline is an orally active haemorheological agent for the treatment of peripheral vascular disease, cerebrovascular disease and a number of other conditions involving a defective regional microcirculation. Pentoxyfylline acts primarily by increasing red blood cell deformability, by reducing blood viscosity and by decreasing the potential for platelet aggregation and thrombus formation (mechanism unclear). Pentoxyfylline has also proven to have a significant anti inflammatory effect as well as anti oxidant effect, mechanisms considered to be important patho-physiological causes of contrast induced nephropathy.
The increased risk for contrast-induced nephropathy (CIN) in patients with chronic kidney disease (CKD) undergoing coronary angiography (CAG) has been established. Current and historical data on CIN prevention strategies have shown wide variation with respect to the optimal type, route and timing of these therapies. We investigate the role for oral hydration and/or oral sodium bicarbonate administration compared to intravenous hydration and/or sodium bicarbonate in patients with CKD undergoing CAG.
The purpose of this study is to demonstrate the efficacy of alpha tocopherol for prevention contrast-induced nephropathy in CKD patients undergoing elective coronary procedures.
The use of N-acetylcysteine and ascorbic acid reduce the incidence of radiographic contrast agent induced reduction in renal function in Intensive Care Unit patients.
The aim of this study is to determine whether sodium bicarbonate is superior to sodium chloride in preventing contrast induced nephropathy in diabetic patients undergoing coronary angiography or intervention.
The purpose of this research is to determine the relationship between novel blood tests for heart function (including hormones and heart enzymes measured in the blood), and assess for kidney damage before and after angiography (cardiac catheterization). We hypothesize that these novel tests will enable us to predict possible complications of catheterization immediately after the procedure.
