    Scientists Identify New Potential Benefits of Statins Beyond Lowering Cholesterol

    Statins are a class of drugs that lower cholesterol levels in the blood. They work by blocking an enzyme in the liver that is responsible for producing cholesterol.

    Recent research links the cholesterol-lowering drugs to a lower risk of bleeding stroke. 

    According to recent research individuals who use statins, a class of drugs that decrease cholesterol levels may have a decreased risk of an intracerebral hemorrhage. Intracerebral hemorrhage is a type of stroke caused by bleeding in the brain. The study was recently published in the journal Neurology.

    “While statins have been shown to reduce the risk of stroke from blood clots, there has been conflicting research on whether statin use increases or decreases the risk of a person having a first intracerebral hemorrhage,” said study author David Gaist, MD, Ph.D., of the University of Southern Denmark in Odense and a member of the American Academy of Neurology. “For our study, we looked at the lobe and non-lobe areas of the brain to see if the location was a factor for statin use and the risk of a first intracerebral hemorrhage. We found that those who used a statin had a lower risk of this type of bleeding stroke in both areas of the brain. The risk was even lower with long-term statin use.”

    The lobe area of the brain includes most of the cerebrum, including the frontal, parietal, temporal, and occipital lobes. The non-lobe area primarily includes the basal ganglia, thalamus, cerebellum, and brainstem.

    For the study, researchers looked at health records in Denmark and identified 989 people with an average age of 76 who had an intracerebral hemorrhage in the lobe area of the brain. They were compared to 39,500 people who did not have this type of stroke and were similar in age, sex, and other factors.

    They also looked at 1,175 people with an average age of 75 who had an intracerebral hemorrhage in the non-lobe parts of the brain. They were compared to 46,755 people who did not have this type of stroke and were similar in age, sex, and other factors.

    Researchers used prescription data to determine information on statin use.

    Of the total participants, 6.8% who had a stroke had been taking statins for five or more years, compared to 8.6% of those who did not have a stroke.

    After adjusting for factors like high blood pressure, diabetes, and alcohol use, researchers found that people currently using statins had a 17% lower risk of having a stroke in the lobe areas of the brain and a 16% lower risk of stroke in the non-lobe areas of the brain.

    Longer use of statins was associated with a lower risk of stroke in both areas of the brain. When using statins for more than five years, people had a 33% lower risk of having a stroke in the lobe area of the brain and a 38% lower risk of stroke in the non-lobe area of the brain.

    “It’s reassuring news for people taking statins that these medications seem to reduce the risk of bleeding stroke as well as the risk of stroke from blood clots,” Gaist added. “However, our research was done in only the Danish population, which is primarily people of European ancestry. More research should be conducted in other populations.”
