Coronary heart disease - CHD
Like any muscle, the heart
needs a constant supply of oxygen and nutrients that are carried to it by the
blood in the coronary arteries. When the coronary arteries become narrowed or
clogged and cannot supply enough blood to the heart, the result is CHD. If not
enough oxygen-carrying blood reaches the heart, the heart may respond with pain
called angina. The pain is usually felt in the chest or sometimes in the left
arm and shoulder. (However, the same inadequate blood supply may cause no
symptoms, a condition called silent angina.)
When the blood supply is
cut off completely, the result is a heart attack. The part of the heart that
does not receive oxygen begins to die, and some of the heart muscle may be
permanently damaged.
Causes
CHD is caused by a thickening of the inside walls of
the coronary arteries. This thickening, called atherosclerosis, narrows the
space through which blood can flow, decreasing and sometimes completely cutting
off the supply of oxygen and nutrients to the heart.
Atherosclerosis usually occurs when a person has high
levels of cholesterol, a fat-like substance, in the blood. Cholesterol and fat,
circulating in the blood, build up on the walls of the arteries. The buildup
narrows the arteries and can slow or block the flow of blood. When the level of
cholesterol in the blood is high, there is a greater chance that it will be
deposited onto the artery walls. This process begins in most people during
childhood and the teenage years, and worsens as they get older.
In addition to high blood cholesterol, high blood
pressure and smoking also contribute to CHD. On the average, each of these
doubles your chance of developing heart disease. Therefore, a person who has all
three risk factors is eight times more likely to develop heart disease than
someone who has none. Obesity and physical inactivity are other factors that can
lead to CHD. Overweight increases the likelihood of developing high blood
cholesterol and high blood pressure, and physical inactivity increases the risk
of heart attack. Regular exercise, good nutrition, and smoking cessation are key
to controlling the risk factors for CHD.
Symptoms of CHD
Chest pain (angina) or shortness of breath may be the
earliest signs of CHD. A person may feel heaviness, tightness, pain, burning,
pressure, or squeezing, usually behind the breastbone but sometimes also in the
arms, neck, or jaws. These signs usually bring the patient to a doctor for the
first time. Nevertheless, some people have heart attacks without ever having any
of these symptoms.
It is important to know that there is a wide range of
severity for CHD. Some people have no symptoms at all, some have mild
intermittent chest pain, and some have more pronounced and steady pain. Still
others have CHD that is severe enough to make normal everyday activities
difficult.
Because CHD varies so much from one person to another,
the way a doctor diagnoses and treats CHD will also vary a lot. The following
descriptions are general guidelines to some tests and treatments that may or may
not be used, depending on the individual case.
Tests for CHD:
- An electrocardiogram (ECG or EKG)
is a graphic record of the electrical activity of the heart as it contracts
and rests. Abnormal heartbeats and some areas of damage, inadequate blood
flow, and heart enlargement can be detected on the records.
- A stress test (also called a
treadmill test or exercise ECG) is used to record the heartbeat during
exercise. This is done because some heart problems only show up when the
heart is working hard. In the test, an ECG is done before, during, and after
exercising on a treadmill; breathing rate and blood pressure may be measured
as well. Exercise tests are useful but are not completely reliable; false
positives (showing a problem where none exists) and false negatives (showing
no problem when something is wrong) are fairly common.
- Nuclear scanning
is sometimes used
to show damaged areas of the heart and expose problems with the heart's
pumping action. A small amount of radioactive material is injected into a
vein, usually in the arm. A scanning camera records the nuclear material
that is taken up by heart muscle (healthy areas) or not taken up (damaged
areas).
- Coronary angiography (or
arteriography) is a test used to explore the coronary arteries. A fine tube
(catheter) is put into an artery of an arm or leg and passed through the
tube into the arteries of the heart. The heart and blood vessels are then
filmed while the heart pumps. The picture that is seen, called an angiogram
or arteriogram, will show problems such as a blockage caused by
atherosclerosis.
Treatment Of CHD
CHD is managed with lifestyle changes and medications.
Others with severe CHD may need surgery. In any case, once CHD develops, it
requires lifelong management.
Lifestyle changes
Changing your diet to one low in fat, especially
saturated fat, and cholesterol will help reduce high blood cholesterol, a
primary cause of atherosclerosis. In fact, it is even more important to keep
your cholesterol low after a heart attack to help lower your risk of having
another one. Eating less fat should also help you lose weight. If you are
overweight, losing weight can help lower blood cholesterol and is the most
effective lifestyle way to reduce high blood pressure, another risk factor for
atherosclerosis and heart disease.
People with CHD can also benefit from exercise. Recent
research has shown that even moderate amounts of physical activity are
associated with lower death rates from CHD. However, people with severe CHD may
have to restrict their exercise somewhat. If you have CHD, check with your
doctor to find out what kinds of exercise are best for you.
Smoking is one of the three major risk factors for CHD.
Quitting smoking dramatically lowers the risk of a heart attack and also reduces
the risk of a second heart attack in people who have already had one.
Surgery
Coronary angioplasty
or balloon angioplasty begins with a procedure similar to
angiography. However, the catheter positioned in the narrowed coronary artery
has a tiny balloon at its tip. The balloon is inflated and deflated to stretch
or break open the narrowing and improve the passage for blood flow. The
balloon-tipped catheter is then removed.
In a coronary artery bypass operation,
a blood vessel, usually taken from the leg or chest, is grafted onto the blocked
artery, bypassing the blocked area. If more than one artery is blocked, a bypass
can be done on each. The blood can then go around the obstruction to supply the
heart with enough blood to relieve chest pain.
Bypass surgery relieves symptoms of heart disease but
does not cure it. Usually you will need to make a number of changes in your
lifestyle after the operation. If your normal lifestyle includes smoking, a
high-fat diet, or no exercise, changes are advised.
High Blood
Pressure / Hypertension
Many people have high blood
pressure for years without knowing it. Uncontrolled high blood pressure can
lead to stroke, heart attack, heart failure or kidney failure. The only way to
tell if you have high blood pressure is to have your blood pressure checked.
According to recent estimates, one in four U.S. adults has high blood pressure,
but because there are no symptoms, nearly one-third of these people don't even
know they have it. This is why high blood pressure is often called the
"silent killer." More...
High
Cholesterol / Hypercholesterolemia
Hypercholesterolemia,
or high cholesterol, is a high level of cholesterol in the
blood that can cause plaque to form and accumulate leading to
blockages in the arteries (atherosclerosis), increasing the
risk for heart attack, stroke, circulation problems, and
death.
