The causes of some "White Coat Hypertension".
Frank Russo - April 21, 2008
These's no doubt that some hypertension is caused by the nervousness and ambience of the measurement. However, with the advent of do-it-yourself machines, it is obvious that this does not represent the whole picture in "white coat hypertension".
It is a fact that the arterial wall has to collapse so as to occlude the vessel and thus bring about a cessation of the heart-beat near there. Now the arterial wall is fairly complex incorporating an intima, a muscle layer and an elastic layer. Obviously there would be variations in the strength of the arterial walls from one individual to another... hence a person with strong walls will find that their pressure will appear higher simply because the walls will un-collapse themselves at a higher pressure.
The answer to this is to do repeat measurements on the same arm at a particular time interval... interestingly the energy of the arterial wall will thus diminish, and the pressure will better reflect the heart function rather than any local arterial wall strength.
