The term coronary heart disease covers a
group of clinical syndromes arising particularly from
failure of the coronary arteries to supply sufficient
blood to the heart. They include angina pectoris,
coronary thrombosis or heart attack and sudden death
without infarction.
There has been a marked increase in the incidence of
heart disease in recent years. Heart attacks have become
the number one killer in western countries. They rank
third in India , after tuberculosis and infections. The
disease affects people of all ages and both sexes,
although it is more common in men than in women,
especially in those aged 40-60 years.
The heart, the most vital organ in the body, is a muscle
about the size of a clenched fist. It starts working even
before birth inside the womb. Weighing about 300 grams,
it pumps about 4,300 gallons of blood every day through
the body and supplies oxygen and nourishment to all the
organs. It beats 1,00,000 times a day, continually
pumping the blood through more than 60,000 miles of tiny
blood vessels. The heart, in turn, needs blood for its
nourishment, which is supplied by coronary arteries.
In the event of narrowing or hardening of the arteries on
account of their getting plugged with fatty substances,
the flow of blood is restricted. The heart then does not
get sufficient oxygen. This condition is known as
ischaemia of the heart or angina pectoris, which is a
latin word meaning pain in the chest. It is actually a
cry of the heart for more blood. In this condition,
exercise or excitement provokes severe chest pain and so
limits the patients physical activity. It serves as
a warning to slow down and prompt preventive measures
will prevent a heart attack.
If the narrowed arteries get blocked due to a clot or
thrombus inside them, causing death of that portion of
the heart which depends upon the choked arteries, it is
called a heart attack or coronary thrombosis. It may lead
to death or heal, leaving a scar. Patients with healed
lesions may be severely disabled or may be able to resume
normal life with restrictions in their physical
activities. A high proportion of cases of sudden death
occur in persons who have had angina pectoris or coronary
thrombosis.
The coronary arteries get narrowed due to various
chemical deposits on their inner linings. These are
caused by inherited or acquired defects in the metabolic
processes of the body with regard to intake and
absorption of various substances. A diet rich in fatty
foods, especially animal fats, causes fatty substances to
settle in the coronary arteries, thus blocking and
narrowing them. The process of silting up of arteries is
known as arterioscelrosis and is a major degenerative
change affecting the circulatory system.Symptoms
A common
symptom of heart disease is shortness of breath, which is
caused by the blood being deprived of the proper account
of oxygen. Another common symptom is chest pain or pain
down either arm. Other symptoms are palpitation,
fainting, emotional instability, cold hand and feet,
frequent perspiration and fatigue. All these symptoms may
be caused by many other disorders. Appropriate tests and
studies are, therefore, essential to establish the true
nature of these symptoms.
Causes
The basic
causes of heart disease are wrong food habits, faulty
style of living and various stresses. The famous
Framingham Heart Study of the National Heart and Lung
Institutes identified seven major risk factors in
coronary heart disease. These are : (I) elevated blood
levels of cholesterol, triglycerides and other fatty
substances, (ii) elevated blood pressure (iii) elevated
blood uric acid levels ( mainly caused by a high protein
diet), (iv) certain metabolic disorders, notably
diabetes, (v) obesity, (vi) smoking, and (vii) lack of
physical exercise. Any one or a combination of these risk
factors can contribute to heart disease. Most of them are
of dietary origin. These risk factors can be controlled
by changing ones life style and re-adjusting the
diet. Constant worry and tension stimulates the adrenal
glands to produce more adrenaline and cartisons. This
also contributes to constricted arteries, high blood
pressure and increased work for the heart.
Dietary
Cure
The
fundamental factor in all heart diseases is the diet. A
corrective diet designed to alter body chemistry and
improve the quality of general nutritional intake can, in
many cases, reverse the degenerative changes which have
occurred in the heart and blood vessels.
The diet should be lacto-vegetarian, low in sodium and
calories. It should consist of high quality, natural
organic foods, with emphasis on whole grains, seeds,
fresh fruits and vegetables. Foods which should be
eliminated are all white flour products, sweets,
chocolates, canned foods in syrup, soft drinks, squashes,
all hard fats of animal origin such as butter, cream and
fatty meats. Salt and sugar should be reduced
substantially.
Most flesh foods have a high sodium content and some
meats are also very fatty. They are also highly
acid-forming and create a high level of toxic matter in
the system. They should be avoided by patients with a
heart disease. The patient should also avoid tea, coffee,
alcohol and tobacco. Tea and coffee contain caffeine
which has a toxic effect on the heart and nervous system.
Caffeine is a strong cardiac stimulant, which if taken
regularly can cause palpitation or disturbances of heart
rhythm.
Alcohol damages the liver and overstimulates the heart.
It also alters the blood sugar level and depletes the
bodys vitamin B reserve. Nicotine has a toxic,
irritant effect on the heart muscles and disturbs the
blood sugar level.
The diet of the patient with heart disease should consist
of nutrients as near to their whole natural state as
possible so as to ensure an adequate intake of essential
vitamins, minerals and trace elements. Fruits and
vegetables should form a large part of the diet and
should be taken in their fresh raw state whenever
possible. Grapes and apples are particularly beneficial.
The essential fatty acids which reduce serum cholesterol
levels and minimise the risk of arterioscelerosis can be
obtained from sunflower seed oil, corn oil or safflower
oil. Several studies have indicated that garlic can
reduce the cholesterol level in persons whose body
normally cannot regulate it. Another important
cholesterol lowering herb is alfalfa. Lecithin helps
prevent fatty deposits in arteries. Best food sources are
unrefined, raw, crude vegetable oils, seeds and grains.
Patients with heart disease should increase their intake
of foods rich in vitamin E, as this vitamin promotes
heart functioning by improving oxygeneration of the
cells. It also improves the circulation and muscle
strength. Many whole meal products and green vegetables,
particularly the outer leaves of cabbage, are good
sources of vitamin E. The vitamin B group is important
for heart and circulatory disorders. The best sources of
vitamin B are whole grains.
Vitamin C is also essential as it protects against
spontaneous breaks in capillary walls which can lead to
heart attacks. It also guards against high blood
cholesterol. The stress of anger, fear, disappointment
and similar emotions can raise blood fat and cholesterol
levels immediately but this reaction to stress can do
little harm if the diet is adequate in vitamin C and
panthothenic acid. The richest sources of vitamin C are
citrus fruits.
The following is the suggested diet for persons suffering
from some disorder of the heart :
Upon
arising : Lukewarm water with lemon juice and
honey.
Breakfast
: Fresh
fruits such as apples, grapes, pears, peaches,
pineapples, oranges, melons, one or two slices of whole
meal bread and skimmed milk.
Mid-morning
: Fresh fruit
juice or coconut water.
Lunch
: Combination
salad of vegetables such as lettuces, cabbage, endive,
carrots, cucumber, beetroot, tomato, onion and garlic,
one or two slices of wholemeal bread or chappatis and
curd.
Mid-afternoon
: Fresh fruit
juice.
Dinner
: Fresh
vegetable juice or soup, two steamed or lightly cooked
vegetables, one or two whole wheat chappatis, and a glass
of butter-milk.
The patient should also
pay attention to other laws of nature for health building
such as taking moderate exercise, getting proper rest and
sleep, adopting the right mental attitude and getting
fresh air and drinking pure water.
