One of the great success stories of medical research in recent years has
been in the understanding and control of high blood pressure,
Before 1950 there was virtually no treatment and high blood pressure
often resulted in strokes, heart failure and sometimes blindness. The basic
cause of the condition, namely undue constriction of the small arteries of the
body, may be due to more than one condition. Intensive research has been
directed to the mechanism of arterial constriction especially in relation to the
result of this, laboratory and clinical research medicines have been
body salt content, abnormalities in the kidneys and endocrine organs. As a
developed which can treat the high blood pressure by either regulating the
salt content of the body or relaxing the constriction of the arteries.
The result is that most cases of high blood pressure can now be well
controlled and patients lead long and normal lives.
