Aortic Calcification Found to Be Widespread
A team led by Marlies Noordzij, MSc, of the
Of the 428 patients, 205 (53%) had moderate AC and 96 (25%) had severe AC at baseline. Thirty percent of these patients experienced progression, defined as an increase in AC between the first and last evaluated x-ray. The mean time between and baseline calcification score and the last available score was 27 months, according to the investigators. These results indicate that plain chest x-rays can be useful for screening dialysis patients for aortic calcification.
Patients who had AC progression had a nearly threefold higher risk of cardiovascular mortality and a nearly twofold higher risk of all-cause mortality compared with those who did not have progression, Dr. Noordzij's group reported.
Findings were presented here at the European Renal Association-European Dialysis and Transplant Association 2008 congress.
