Heart Assist Doesn’t Assist?

High-risk patients with weakened hearts don’t benefit significantly when a device that keeps blood pumping through the body is used during angioplasty procedures to re-open narrowed coronary arteries. That was the main finding of a study that was published August 25 in the Journal of the American Heart Association.

The device in question is an intra-aortic balloon pump (IABP), which is placed inside the aorta, the main artery supplying blood to the body. It can be used throughout the artery-clearing procedure or as a rescue device if blood pressure falls too low.

Among 301 patients treated in 17 cardiac centers in the United Kingdom between December 2005 and January 2009, no significant differences were found in death rates, heart attacks, strokes or the need for more angioplasty procedures.

The study was conducted by researchers led by Simon Redwood, MD, of St. Thomas’ Hospital in London. They concluded that results “do not support a strategy of routine IABP placement” before angioplasty in high-risk patients.

Intra-aortic balloon pumps also can be used for cardiac support immediately after open heart surgery and in critically ill patients.

Question for comment: Have you or someone you know ever relied on an IABP device during surgery?
