Brief Summary:
The purpose of this study is to demonstrate that Iodixanol 320 is associated with a lower incidence of contrast-induced nephropathy (CIN) when compared with hyperosmolar contrast medium Iomeprol 350 in patients with impaired renal function undergoing percutaneous coronary interventions (PCI).

Condition or disease Intervention/treatment Phase
Renal Insufficiency, Chronic Angioplasty, Transluminal, Percutaneous Coronary Coronary Arteriosclerosis Drug: Iodixanol 320 Drug: Iomeprol 350 Phase 4

Detailed Description:

Iodixanol, an iso-osmolar, dimeric, non-ionic contrast agent has been shown to reduce the risk of developing CIN in patients with elevated serum creatinine concentrations compared to low-osmolar contrast agents. However, no information is available about a potential protective effect of Iodixanol in patients with impaired renal function on CIN when used during PCI. Due to the high volume of contrast exposition, patients with impaired renal function are at increased risk for the development of CIN compared to patients with normal excretory renal function.

The purpose of the investigation is to determine the changes of renal function in patients with impaired renal function receiving Iodixanol 320 or Iomeprol 350 for percutaneous coronary intervention.
