Summary:
The Society for Cardiovascular Angiography and Interventions (SCAI) has released recommendations for the prevention of contrast induced nephropathy (CIN) -- potentially fatal kidney damage that can occur when a special dye is injected during certain cardiovascular procedures. The consensus document, the first to be written on this topic, appears in the January 2007 issue of Catheterization and Cardiovascular Interventions: Journal of the Society for Cardiovascular Angiography and Interventions.

The Society for Cardiovascular Angiography and Interventions (SCAI) has released recommendations for the prevention of contrast induced nephropathy (CIN) -- potentially fatal kidney damage that can occur when a special dye is injected during certain cardiovascular procedures. The consensus document, the first to be written on this topic, appears in the January 2007 issue of Catheterization and Cardiovascular Interventions: Journal of the Society for Cardiovascular Angiography and Interventions.

Contrast dye is essential for many diagnostic and interventional cardiovascular procedures because it enables doctors to visualize blocked blood vessels, said Dr. Marc J. Schweiger, lead author of the SCAI consensus document. "As interventionalists, we work with contrast media every day, so it is crucial that we know how to avoid CIN, with its associated morbidity and mortality."

Dr. Schweiger stressed that CIN is relatively rare; the condition is estimated to occur in 1--3 percent of individuals who undergo interventional cardiovascular procedures in which contrast dyes are used. Patients at greatest risk are the elderly, and those with diabetes, chronic kidney disease, or advanced heart failure. "Nevertheless, we feel that 3 percent is too high a rate, and a lot can be done to lower the risk," Dr. Schweiger said.

In developing the consensus statement, members of SCAI's Catheterization Laboratory Performance Standards Committee (chaired by Dr. Charles E. Chambers) reviewed all of the published literature addressing ways to minimize the risk of CIN. Among the Society's key recommendations are the following:

  1. Do the right tests to properly assess a patient's kidney function. -- In most cases, physicians can get an accurate measure of how well a patient's kidneys are working by estimating the glomerular filtration rate, or eGFR. This test is superior to the often-used serum creatinine test.
  2. Make sure patients are adequately hydrated before, during, and after the procedure. -- "Hydration is very important in preventing CIN," Dr. Schweiger said. "High-risk patients should come for their procedure in plenty of time to be properly hydrated using intravenous hydration."
  3. Address with patients whether to discontinue the use of non-steroidal anti-inflammatory (NSAID) agents 24--48 hours before a procedure. -- Medications such as ibuprofen and Naprosyn are known as NSAIDs and are usually taken for aches and pains associated with arthritis, headache, back injury, and other ailments. These medications can potentially cause a kidney problem by decreasing blood flow to the kidneys. Because contrast dyes can also decrease kidney blood flow, the two agents should not be given concurrently.
  4. In patients at increased risk for CIN, use contrast agents with lower osmolarity, and in the smallest possible quantities. -- Contrast agents with lower osmolarity are less dense and, therefore, less likely to interfere with blood flow to the kidneys.
  5. Monitor patients at increased risk for CIN very closely for up to 48 hours after a procedure that involved the use of contrast dye. -- Physicians and nurses should be on the lookout for any signs of kidney failure. During this period, the serum creatinine test is useful for monitoring kidney function. In addition, patients should not resume taking NSAIDs until their kidney function has returned to normal.

CIN is a rare complication and, in most cases, is preventable, Dr. Schweiger stressed. "We certainly do not want to discourage people from having a procedure they really need because of fears of a complication that is unlikely to occur. The benefits of undergoing most diagnostic and interventional procedures far outweigh any risks associated with the use of contrast dye in such procedures," he said. "In fact, contrast dyes have helped us make enormous progress in the treatment of patients with blocked arteries."

About SCAI

Headquartered in Washington, DC, the Society for Cardiovascular Angiography and Interventions is a 3,700-member professional organization representing invasive and interventional cardiologists. SCAI's mission is to promote excellence in invasive and interventional cardiovascular medicine through physician education and representation, and advancement of quality standards to enhance patient care. SCAI was organized in 1976 under the guidance of Drs. F. Mason Sones and Melvin P. Judkins. The first SCAI Annual Scientific Sessions were held in Chicago in 1978.
