Researchers at the Chinese University's Faculty of Medicine say they’ve found that patients who are of Chinese ethnicity are at higher risk of death if they develop a complication linked to blood thinning treatment for heart disease.

The study analysed the clinical and imaging data of 232 patients who experienced an intracerebral haemorrhage between 2016 and 2021. It found that 70 percent of Chinese patients had a poor neurological outcome and almost 40 percent died within 90 days.

European and American studies, meanwhile, found that only around 50 percent of patients suffered severe neurological disability and there was a 28 percent mortality rate.

“This is a very impactful finding,” said Dr Bonaventure Ip, an assistant professor of neurology.

“Such a study has never been performed among the Asian or Chinese patients. That is exactly why we need to have a better management strategy for patients [with the disease]."

Direct oral anticoagulants are widely used to reduce the risk of stroke, as the drug prevents clots from forming inside blood vessels. However, one in every thousand patients face the risk of developing intracerebral haemorrhage.

The findings were released on Monday, to mark World Brain Day.

The team said people should maintain healthy habits, such as eating a balanced diet, exercise regularly and avoiding excessive alcohol consumption. They say such habits are especially important for people with atrial fibrillation.

The team also urged people to immediately seek help if they experience symptoms of stroke, including inability to move one side of their limbs, facial asymmetry, drooling of saliva and slurring of speech.
