According to a study conducted by some researchers of Denmark, risk of having a stroke in women can’t be predicted by the high levels of cholesterol though they could easily detect an increased risk in men only when cholesterol level was almost twice the average level.

The report was published in Annals of Neurology and it used a different type of fat in the blood, non-fasting triglycerides, to measure the risk.

Data suggests that more than 150,000 people suffer a stroke in UK every year and most of them are ischemic strokes in which a clot in an artery disrupts the brain's blood supply.

Copenhagen City Heart study was conducted on 13,951 and findings suggest that cholesterol levels in women were not related to the risk of stroke while there was only an association in men with levels higher than 9mmol/liter.

Explaining the nature of the issue, experts said that these fats form remnant cholesterol which is left behind when other forms of cholesterol are made.

Dr. Peter Coleman, Deputy Director of research at The Stroke Association said, "Tests for triglyceride levels aren't routinely carried out in the UK unless there is significant concern. However, this research shows the importance of measuring the fat triglyceride, as well as cholesterol. This study highlights the importance of measuring triglycerides routinely in order to reduce a person's risk of stroke”.
