Hypertension
Everyone needs blood pressure to move blood through
the circulatory system. Blood pressure o created by contrac-
tions of the bean muscle, which pumps the blood through the
vessels, and by the resisunce of the arterial walls. With each
beat of the heart, blood pressure goes up and down within a
limited range. When it goes up and stays up, it is called high
blood pressure, also known as hypenension.
High blood pressure is a silent, mysterious killer...silent
because it has no characteristic sympt s; mysterious be-
cause, in more than 90 percent of theases, the cause n
unknown, and there is no cure. 0 hypertension is not
controlled, serious cardiovascular complications may result.
Hypertension, or high blood pressure, affects nearly 2;000,000
Canadians and in tIese persons the pressure puts an extra
work load upon the heart which is responsible for the
development of hypertensive heart disease.
The tragedy of hypertension is that half the people who
have it ire unaware of the fact and, of those who do know, it is
estimated that only one in lour ate receiving adequate
treatment. Research has developed drugs and other means of
controlling high blood pressure in most cases. High blood
pressure can result in stroke, congestive heart failure and
kidney failure and is a major risk factor in coronary artery
disease.
We know that the person whose systolic blood pressure is
over 150 has 2 times more risk of having a heart attack than the
person with a systolic blood pressure under 120and 4 times the
chance of suffering a stroke. The importance of early diagnosis
and adequate treatment of hypertension are obvious in the
light of these facts.
There are several types of hypertension. Some people
suffer from occasional periods of elevated pressure; some
have sustained, but modest, elevations of blood pressure,
sometimes referred to as "essential" hypertension; and others
have a severe.and persistent elevation — often referred to as
"malignant" hypertension.
While the exact cause of primary or essential hypertension
is unknown, certain factors contribute to 0. The kidneys, for
instance, may release a substance into the bloodstream which
triggers a chain of chemical events leading to high blood
pressure. Hypertension may also be cause by long-standing
kidney disease, orcertain abnormalities ofthe adrenal or other
endocrine glands. fmottol5s are thought by rnanyto playa role
in increasing the blood pressure.
Rheumatic
Heart Disease
Rheumatic fever is usually considered a disease of child--
hood,
hild-hood, striking during the school-age years. It is usually
preceded by a "strep" infection, which, for reasons not
understood, results in the development of rheumatic fever in
certain children some ten to fourteen days after the "strep"
infection clean up. It should be noted that very few "seep"
infections are followed by the onset.of rheumatic lever.
Rheumatic fever is ohen recurrent, particularly following
subsequent "strep" infections arsd recurrent attacks may lead
to rheumatic heart disease, in which the valves of the heart are
scarred and deformed. Luckily rheumatic heart disease can
usually be prevented by the use of antibiotics to treat "strep"
infection arsd by long-term administration of antibiotics to
rheumatic fever patients to prevent recurrence of the disease
and subsequent heart damage.
The development of open-heart surgery has dramatically
changed the outlook for those whose heart valves have been
scarred or deformed — about 85% of cases can now be cured
by surgical techniques.
Congenital Defects
Congenital defects are congenital malformations of the
heart or its major blood vesseh which are caused by abnormal
development of the embryo. Some defects are hereditary;
others are caused when a pregnant woman fs exposed to
diseases such as German measles, or to chemical toxins. In all,
there are 35 recognizable types of defects.
The most common defects are holes in the wall dividing
the lower chambers a the upper chambers of the heart. These
defects can often be detected at birth because of the unusual
murmur the heart makes with each beat. Other defects affecting
major arteries may require highly elaborate tests for accurate
diagnosis and these tests often cannot be undertaken until the
infant n several months old.
Again, the great progress in recent years in cardiovascular
surgery has made it possible to correct many of these defects
surgically and extend the life expectancy and quality of these
children.

Evidence that cardiovascular research
pays off is reflected in this arrow flow
chart. The overall death tate from heart
and blood vessel disease for people
under 65 is down 31% since 1955. Marked
reductions have been achieved in deaths
due to stroke, high blood pressure and
most other forms of .heart disease BUT,
in HEAR1 ATTACK. the single leading
killer, the decline has been 21%
Thousands of Canadians are currently
living, who would have died prematurely
if 1955 death rates prevailed today.
