TUESDAY, Sept. 23, 2014 (HealthDay News) -- People using cholesterol-lowering drugs while in the hospital for a hemorrhagic stroke -- which causes bleeding in the brain -- were more than four times more likely to survive than people who weren't taking the drugs, according to a new study.
People taking the commonly used drugs known as statins were also 2.5 times more likely to be discharged home or to a rehabilitation facility, the study reports.
When it comes to the best treatment for hemorrhagic stroke, there hasn't been a standard treatment recommendation, according to the study's lead author, Dr. Alexander Flint, the medical director of neuroscience quality at Kaiser Permanente in Redwood City, Calif. Now, he said, physicians should know that taking patients off statin treatment in the hospital "may carry a risk of substantially worse outcome."
The findings from this study aren't considered definitive because it wasn't designed to prove that the statin treatment directly caused the lower risk of death.
There are two types of stroke -- ischemic and hemorrhagic, according to the National Institute of Neurological Disorders and Stroke. Ischemic strokes are caused by a blockage in a blood vessel in the brain. A hemorrhagic stroke is caused by bleeding from a blood vessel in the brain.
According to Flint, hemorrhagic strokes are less common, comprising about 15 to 20 percent of all strokes. But, hemorrhagic strokes are often more damaging -- as many as 40 percent of people who have a hemorrhagic stroke die within a month, he said.
Previous research has shown that cholesterol-busting statin drugs help after ischemic strokes, Flint said. But, he added, there have been conflicting findings about statin use in hemorrhagic strokes. The goal of this study was to help shed light on the best approach for those patients.
The study authors examined the medical records of almost 3,500 people treated for hemorrhagic strokes at 20 Kaiser Permanente hospitals in Northern California over a decade.
The researchers found that those who took statins in the hospital were much more likely to be alive after 30 days and more likely to leave the hospital for home or a rehabilitation facility.
