ce the balloon is in place, a pump is used to expand and contract it. When
the balloon expands, it helps improve delivery of oxygenated blood to all the
body's tissues and to the heart muscle itself.
To conduct the retrospective study, the researchers used the National
Registry of Myocardial Infarction 2, a data base maintained by Genentech.
The researchers identified 21,718 patients who had acute heart attacks and
who arrived at the hospital with cardiogenic shock or else developed the
condition while in the hospital. Of the 21,178 patients studied, 6993
received the balloon pump treatment.
Cardiogenic shock is a life-threatening condition in which, as a result
of the heart's failure to pump, blood pressure drops too low to maintain the
functioning of other organs. More often than not, cardiogenic shock leads to
Barron says use of a pump may improve delivery of a thrombolytic drug to
the site of heart-attack causing clot, thereby boosting prospects for breaking
up the clot and restoring blood flow to the oxygen-starved heart.
