With all the prevention possibilities out there your stroke association and doctor should be able to tell you exactly what you need to do to not have a stroke. Don't take 'I don't know' for an answer. They were trained for these types of questions.

University of Minnesota Medical School researchers have collaborated
with the School of Public Health and discovered an enzyme that, when
found at high levels and alongside low levels of HDL (good cholesterol), can dramatically reduce the risk of cardiovascular disease.
The enzyme - glutathione peroxidase, or GPx3 - is a natural antioxidant
that helps protect organisms from oxidant injury and helps the body
naturally repair itself. Researchers have found that patients with high
levels of good cholesterol, the GPx3 enzyme does not make a significant
difference. However, those patients with low levels of good cholesterol,
the GPx3 enzyme could potentially be a big benefit. The enzyme's link
to cardiovascular disease may also help determine cardiovascular risk in
patients with low levels of good cholesterol and low levels of the
protective GPx3.
The new research, published by PLoS One, supports the view that natural antioxidants may offer the human body profound benefits.
"In our study, we found that people with high levels of the GPx3 enzyme
and low levels of good cholesterol were six times less likely to develop
cardiovascular disease than people with low levels of both," said lead
author Jordan L. Holtzman, M.D., Ph.D., professor of pharmacology and
medicine within the University of Minnesota Medical School. "This GPx3
enzyme gives us a good reason to believe that natural antioxidants like
GPx3 are good for heart health."
The combination of low HDL and low GPx3 affects an estimated 50 million
people - one in four adults - in the U.S. This condition can lead to
fatal heart attacks and strokes.
Researchers continue to look for new ways to better predict who is at
risk for these diseases and how patients can limit the impact of the
disease once it's diagnosed.
"It's important to point out that people should not rush out to their
doctors and demand testing for the GPx3 enzyme," said Holtzman. "But in
time, we hope that measuring this enzyme will be a common blood test
when determining whether a patient is at risk for cardiovascular
disease, including heart attacks and strokes."
To arrive at his results, Holtzman and his colleagues studied the three major risk factors for cardiovascular disease: hypertension,
smoking and high cholesterol. Data suggests that those with low levels
of HDL and GPx3 were six times more likely to die from cardiovascular
disease, including heart attack or stroke, than those with low levels of
HDL and high levels of GPx3.
The study examined 130 stored samples from the Minnesota Heart Survey
from participants who died of cardiovascular disease after 5-12 years of
follow-up care. The ages of patients studied ranged from 26-85 years
old. Their data was compared to 240 control samples.
"This is an important enzyme for people with low HDL cholesterol," said
Holtzman. "We think further research will be important in determining
the future role of GPx3 and what drugs may serve to increase its
activity in the blood."
