Hi All,

I have recently had a blood pressure reading taken on a home digital
meter (wrist cuff) - this is an unusual occurrence for me, but it
correlates with another reading taken a couple of years ago (that I
didn't follow up): it was 150/75. I'm 36 years old and quit smoking
last year, although for the 3 years previous to that I had a very
light habit (1-2 cigarettes a day). I exercise regularly - although
I'm currently only exercising lightly due to a calf injury, my normal
weekly load would be: 5 days cycle-commuting for about 15km a day; 2
hour long (very strenuous)  5-a-side football games; 1km (or
thereabouts) of pool swimming; 1 or 2 long off-road cycles, normally
in the 30-50km range, normally with 1-2km of total vertical ascent.
I'm 1m85 tall and I weigh 93kg. I have some family history - well,
certainly among my uncles - of mild hypertension (although that may be
linked to a general love of good food and fine wine!) and my father
suffered a fatal MI aged 69, but that is the only heart-attack that I
know of in the family, my grandfather having died after a fall from a
ladder aged 73.

What is the likely cause of the abnormally high systolic reading?
Should I be worried?

Cheers - Adam...
