Causes of heart diseases
Heart diseases are more frequent in people who show peculiar personality
physical and mental traits. Coronary heart disease is considered to
have multiple causative factors i.e., no one single factor perhaps
could be identified as one causing a heart attack.
- Heredity:
There is ample evidence to show that incidence of heart disease
is more in persons whose direct predecessors like fathers, grandfathers,
mothers, brothers have suffered from similar disease. Coronary
artery disease is found to run mainly in families. A strong family
history of the disease is important in diagnosis.
- Stress:
Heart disease has often been identified with certain personality
patterns. It is labelled as personality disease or a high executive
disease, that is, it strikes persons with a certain personality.
A certain study has shown that there was four times as much coronary
disease among aggressive type of individuals.
In addition to this other factors such as family responsibilities,
interpersonal relationship, financial worries, leisure interests,
habits of eating drinking and smoking etc. may play a part that
may effect one's heart.
- Smoking:
It has been found by some workers that death rate among those
who had heart attack was 50-150 percent higher in those who were
heavy cigarette smoker than non-smokers.
- Physical Exercise:
There is a fairly general trend towards encouraging regular physical
effort of a kind suited to age and condition of the person concerned.
As a preventive as well as a remedial measure exercise is of great
importance. There is abundant evidence to suggest that a stressful
sedentary life without much exercise provides a situation fraught
with coronary danger. Death rate from coronary heart disease is
lower among those who do strenuous physical work.
Even for patients, who have survived coronary attacks, there has
lately been a change in the thinking in marked contrast in earlier
ideas. The doctors are now a day advocating, after the initial
prescribed rest, walking up the stairs, going on hikes, bicycles
and other forms of exercise. The quantum of exercise in each case
must of course be decided by the attending physician.
- Diet and obesity:
Studies have shown 50 percent increase in heart attacks in employees
who were over weight. Similarly diet and amount of fat are matter
of vital importance. The sound advice which could be given is
to lead a life of moderation in matter of diet and activity an
also to avoid obesity. Large fatty meals and strenuous exercise
after them is not conducive to a healthy heart.
Saturated fats such as whole milk, cream, butter, cheese meat,
fat, etc raise blood cholesterol level. On the other hand unsaturated
fats are of vegetable origin and they tend to lower blood cholesterol
levels like maize oil, cottonseed oil sunflower oil and fat of
fish.
