Yet Another Study Proves Safety Of Ultrasound Contrast
NEW YORK (Reuters Health), Aug 10 - Contrary to earlier concerns, using contrast agents in echocardiography does not lead to more myocardial infarctions (MIs) or deaths, a new meta-analysis has shown.
"This analysis should put to rest the concerns about the safety of echo contrast agents. The usefulness of these agents has been shown in many studies and they should be used in these clinical situations," senior author Dr. Mouaz H. Al-Mallah told Reuters Health by e-mail.
In October 2007, based on four reported deaths after administration of an ultrasound contrast agent, the U.S. Food and Drug Administration issued a black box warning for all such agents, the researchers note in their paper. Contrast agents were specifically contraindicated in patients with acute cardiopulmonary syndromes, severe pulmonary hypertension, and QT prolongation."
