I started running 27 years ago and have averaged about 30 miles a week for most of those years
except the last several years. I have run many marathons including Pikes Peak twice. I am now 63
years old. I have had elevated blood pressure for about 10 years. My doctor has tried various
combinations of drugs. For about the past 2 years I have been taking the following 3 medications --
(1) Hydrochlorothiazide (a diuretic), (2) Verapamil (a calcium channel blocker), and (3) Benicar (an
angiotensin II receptor antagonist). Even with 3 drugs, my pressure was no better than about 140/85
on average. Starting in January 2003, I began to notice that my breathing would be very labored and
my legs would feel heavy right at the start of a run, and I just felt worse and worse the further I
went -- there was no second wind. Later in the year it got so bad that I was able to run only 2 or 3
miles before I had to quit -- it was just too difficult moving forward. After many tests, nothing
could be found to explain it other than one of the cardiologists suggested it could be left
ventricle hypertrophy caused by years of elevated blood pressure. Also, I tried eliminating each of
the drugs for a while, but my blood pressure would always go up, and there seemed to be no positive
effect on the running problem. After doing a lot of reading about athletics, blood pressure, etc., I
began to wonder if perhaps I was deficient in one or more of the electrolytes and/or minerals that
get removed from the body by the diuretic. Several blood analyses that I had along the way showed
nothing to be out of the normal range, but still I wondered. I had already been consuming foods high
in potassium because of the diuretic, so I decided to try taking a magnesium supplement. Bingo! 800
mg daily of magnesium citrate made an immediate improvement in both my blood pressure and my running
difficulties. My pressure went to about 118/68 and has been there for the last 8 weeks, and my
breathing eased considerably. However, I still had the heavy legs. I decided this might be due to
the calcium channel blocker since one effect of that drug is to decrease muscle contraction. Sure
enough, when I stopped that drug, my muscle problems disappeared, and my blood pressure did not go
up. I've been off of the drug for about 6 weeks now. My running situation now is that I have worked
up to running 4 miles a time. I still have breathing difficulty for about the first 2 miles, and
then it starts to get easy. I finally have some confidence that I can begin to start increasing my
mileage again. So my observation is that at least one of my blood pressure medicines was causing a
running problem, and a magnesium deficiency was causing a running problem and perhaps causing
elevated blood pressure. My next step is to try eliminating the diuretic. By the way, I'm doing this
experimentation with my doctor's knowledge. I monitor my pressure 3 times a days and have been
graphing it versus time for the past year. Can anyone relate to my experience? Any comments on the
magnesium? Has anyone been diagnosed with left ventricle hypertrophy? Does anyone know if the
hypertrophy is reversible if the blood pressure is maintained at a low value for a long time? Larry
