Bypass heart surgeries used to be conducted using heart-lung machines, which carried with it a risk of stroke. Now, one in five bypass surgeries are conducted without the pump, leaving the patient’s heart beating on its own. This new technique isn’t as risk-free as previously thought, according to a study in the New England Journal of Medicine.

The study results initially showed that patients on the pump had similar outcomes to those off the pump, according to a November 5 Associated Press article. “But a year later, the off-pump group had worse outcomes. About 10 percent had either died, had a heart attack, or needed another bypass or procedure, compared with about 7 percent of the on-pump group,” the article states.
