Bad Cholesterol Predicts a Stroke Risk; a Myth!

CholesterolSince years, Cholesterol levels have been thought as the common factor for causing a stroke to an individual. But recently it has been denied by the researchers of this new study conducted at Copenhagen University Hospital.

In general, out of ten strokes almost nine are ischemic strokes. These strokes occur due to obstruction of blood to the brain. This obstruction is generally because of the build-up of fatty deposits inside blood vessels, which in other words is also known as hardening of the arteries or atherosclerosis.

For many people it is the bad cholesterol level that adds to the build-up of these fatty deposits, known as plaques.

But researchers, to overcome this myth investigated 7,579 women and 6,372 men. All these were tested with their non-fasting cholesterol measurements and Triglyceride levels, and were then followed for next 33 years.

Triglycerides are a different type of fat, existing in the body with similar function of contributing to plaque build-up.

During the follow-up period, out of the total, equal number of men and women - 837 were found suffering from ischemic stroke. Among these, in women cholesterol levels were not associated with stroke risk factors, whereas in men, it was. But it existed only in those cases, where cholesterol level was almost double the average level.

However, it was revealed, that elevated levels of triglyceride are associated with an increased stroke risk, both in men and women.
