Low ‘Bad’ Cholesterol Increases Stroke Risk – Research

On 17/Jul/2019 / In Articles

Researchers from the Pennsylvania State University, United States of America, have said maintaining a low level of low-density lipoprotein, or ‘bad’ cholesterol was important for cardiovascular health, but extremely low LDL may also have risks.
According to the New York Times, the researchers studied 96,043 people for an average of nine years, recording their LDL level biennially, tracking cases of haemorrhagic stroke, caused by the rupture of a blood vessel in the brain and found that about 13 per cent of strokes are of the haemorrhagic type.
They also found that compared with people in the normal range for LDL – 70 to 99 milligrammes per deciliter of blood – people who had LDL of between 50 and 69 had a 65 per cent higher risk of hemorrhagic stroke.
“For people with an LDL below 50, the risk nearly tripled. LDL concentrations above 100, on the other hand, were not significantly associated with stroke, even at levels higher than 160,” the researchers stated.
The senior author of the study which was published in the journal, Neurology, Dr Xiang Gao, said the report did not mean that having a high LDL was harmless.
 “High LDL is a risk for cardiovascular disease, and a level above 100 should be lowered. But there is no single answer for everyone. The ideal level varies depending on an individual’s risk factors. We need a personalised recommendation rather than a general rule,” Gao said.
