... analysis of 61 previous studies involving almost 900,000 adults, conducted mostly in western Europe and North America, clearly showed that people with lower total blood cholesterol levels had a lower heart disease death rate.
But the researchers found no relationship between total cholesterol levels and risk of stroke death, especially at older ages and among people with higher blood pressures.
"I don't think they [the findings] muddy the fact that statins, which lower cholesterol, do lower stroke risk," Dr Sarah Lewington said.
Caused by fatty deposits that clog arteries, coronary artery disease is a leading cause of worldwide death.
The deposits build up in the arteries that supply the heart with blood. Narrowing of the arteries and reduction in blood flow to the heart can lead to heart attack and other conditions .. like strokes.
But, In a commentary accompanying the study ... they say, a link between cholesterol and stroke risk "probably exists".
"Because most of the benefit of statins in preventing cardiovascular events can be ascribed to the LDL reduction, it is puzzling that LDL cholesterol is not associated with stroke risk," they wrote.
And further, contrary to the findings in the study, They added that "there is good evidence that lowering blood cholesterol with statins reduces stroke risk."
But no, not from this study there isn't, and no contray equivalent studies are cited.
