10 Ways to Prevent a Stroke

By Eric Van De Graaff, MD May 06, 2009 Posted in: Heart Health

Lists are big.  I love them and so do most people.  For me they do three things.  They give me a pithy, terse overview of a particular subject without the need to delve into it too far.  They validate (or repudiate, as the case may be) my own frame of reference on a subject.  And they spark discussion and controversy.  Although I have no authoritative source on the subject, I believe top ten lists must have originated with the FBI (“most wanted”), or Casey Kasem, or even the Moses’ original “top ten.”  A few years back the American Film Institute generated some controversy by creating lists of the 100 best films of the last 100 years and followed up with other “100 best” lists in sub-genres.  These lists became a rousing success despite (or perhaps because of) initial outrage.  Some people hate these types of rankings—I love them, even if I can’t see why Citizen Kane is the best film ever made.

Well, my lists are unfortunately not quite so fascinating but I’ll give it a shot.  Next week I am scheduled to give a lecture on stroke prevention. For this blog entry I’ll produce my list of the 10 best things you can do to prevent a stroke.

A little background first.  A stroke (synonym: cerebrovascular accident, CVA) occurs when part of the brain is starved of oxygen long enough to do permanent damage.  Many things can interrupt blood flow to the brain.   A vessel with a weakened wall (aneurysm) can rupture and cause bleeding and pressure on a portion of the brain tissue and lead to a hemorrhagic stroke.  A clot can become lodged in one of the vessels—arising from the heart or other vessels in the chest, neck and head—and cut off downstream flow to the area of the brain normally supplied by that vessel.  This last mechanism is the most common scenario and generally results in the classic symptoms of numbness, paralysis, slurring of speech, and weakness.

So here goes.

The ten things you can do to avoid a stroke:

  1. Know and treat your blood pressure

    We have plenty of studies showing that most Americans don’t know what their usual blood pressure is, and most who have high blood pressure are not adequately treated.  Check your pressure periodically and seek treatment advice if your numbers are consistently above 130 over 80.

  2. Don’t smoke, and if you do, quit

    Tobacco use (even light, occasional use) increases the risk of stroke.  On the other hand, quitting produces a rapid drop in risk, as was reported in a study from the Journal of the American Medical Association.

  3. Get thin

    I know, this is easier said than done.  Obesity itself serves as a risk factor for stroke and can also lead to metabolic syndrome, a disorder that involves diabetes, cholesterol abnormalities, and high blood pressure.

  4. Limit alcohol intake

  5. Seek treatment if you have atrial fibrillation

    This irregular rhythm arising in the upper chambers of the heart is generally associated with more advanced age and can dramatically increase your risk of stroke if left untreated.  Anticoagulation with warfarin (Coumadin) is the current treatment of choice (please see my previous post about this medication).

  6. Be aggressive with cholesterol treatment

    Curiously, high cholesterol has not been clearly established as a risk factor for stroke (as it is with heart attacks), but treatment with statin medications (Zocor, Lipitor, Crestor, etc.) decreases stroke risk rather dramatically.

  7. Exercise on a regular basis

    I know, I know.  I have to add this—I’m a cardiologist, after all.

  8. See your doctor regularly if you have any form of vascular disease

    Blockage in any vessel of the body (such as coronary artery disease in the heart) implies that the chance is much higher that blockages exist elsewhere, such as in the carotid arteries of the neck.

  9. Know the symptoms of stroke and seek care immediately

    If we catch this very early we can provide aggressive treatment that may result in full resolution of symptoms.  The American Heart Association has a useful page on this subject.

  10. Keep reading my blog

    Actually, this doesn’t really reduce your risk of stroke, but I couldn’t come up with a tenth item and I wanted and opportunity to insert a shameless plug.
