Minor Strokes May Lead to Major Ones
Study: Stroke or Heart Attack Often Follow Within 10 Years
'Like a Volcano'
The risk may stem in part from increasing age, as well as plaque buildup in
blood vessels, says Graeme Hankey, MD, FRCP, FRACP, of the stroke unit and
neurology department at the University of Western Australia.
Atherosclerosis (the hardening of the arteries) is a risk factor for heart
disease and stroke. It behaves "like a volcano," writes Hankey. That is, it can
seem to lie dormant for a long time before it blows its top by causing sporadic
problems that can have deadly consequences.
In a real volcano, lava is unavoidable. But in the body, you can curb plaque
buildup through diet, exercise, and for some people, medication.
There is room for improvement in long-term prevention strategies in TIA
survivors, say Agra and colleagues.
They don't give many details about prevention methods used by participants,
except that all patients initially took aspirin. The study didn't assign
patients to any particular plan.
After a stroke or TIA, patients are often given blood-thinning or
anticlotting drugs to help avoid future strokes. Lowering blood pressure and
cholesterol, eating healthfully, being active, and following doctors' orders
can also reduce stroke and heart attack risk.
