Research suggests that low lipoprotein cholesterol levels increase hemorrhagic stroke risks, after examining over 100,000 participants. Low LDL cholesterol is thought to have adverse effects on cardiovascular health.
Excessive cholesterol levels are always linked to low-quality health. However, experts argue that the inverse could also be true. For example, MNT reported that women who were 45+ years of age had a higher stroke and hemorrhagic bleeding risks when they had low bad cholesterol levels.
A Neurology-published study stated that low LDL levels could increase bleeding and stroke risks in women and men. Xiang Gao of PSU led the study. Chaoran Ma, who was the first author, stated that they wished to expand current knowledge by measuring LDL cholesterol levels in many people multiple times.
Gao examined over 96043 participants with no history of cancer, stroke or heart attack. The levels were measured at baseline, with further testing done for nine years. In the study, correlations between hemorrhagic stroke risks and LDL cholesterol were examined, adjusted for medication, BP, sex and age. Those with LDL levels below seventy mg/dl face the highest hemorrhagic stroke risks.
Chances of suffering from bleeding strokes were about 169% greater than those whose LDL levels were less than fifty mg/dl, compared to those at seventy mg/dl – ninety-nine mg/dl. For those in the latter range, stroke risks were almost the same.
Usually, LDL levels above 100 mg/dl are considered the best levels for the normal population. It is also lower in those with elevated heart disease risks, stated Gao. They observed that hemorrhagic stroke risks grew in those with LDL levels under seventy mg/dl.
If completely confirmed, this observation could change treatment targets. Balance and moderation are keys, while deciding optimal LDL levels. Those at high risks due to alcohol consumption, high BP or family history should be more careful, stated Ma.
