Angina
Pectoris
Angina Pectoris is a medical term for chest pain caused by a lack
of blood flow to the heart muscle. Angina is almost always caused
by a partial obstruction of the coronary arteries. Other less common
causes of angina include abnormal heart rhythm, drug reactions and
thyroid conditions.
Angina Pectoris can take two different
forms: typical and atypical. Typical angina gives a sensation of
pressure or tightness in the center of the chest or to the left
of the sternum, usually brought on by over-exertion or extreme emotions.
It often radiates to the left shoulder down the inside of the left
arm. Onset is gradual, building in intensity and decreases with
rest.
Atypical angina refers to any symptom
that falls outside the norms for typical angina. Common manifestations
of atypical angina are chest discomfort unrelated to over-exertion
or discomfort not located in the chest.
What
is angina pectoris?
Angina Pectoris is the most common symptom of coronary artery disease.
The majority of patients with angina complain of chest pain, but
can also include shortness of breath, fatigue, indigestion, faintness,
pain in the arm or neck.
What causes angina?
Angina signals that a part of the heart muscle is not receiving
an adequate supply of blood and oxygen. When narrowed or blocked
arteries prevent or restrict blood flow, oxygen supply to portions
of the heart may be insufficient. Increases in oxygen demand can
occur during exercise, when you have a fever, during periods of
hypoglycemia or after meals. This increased demand can trigger the
onset of angina.
How can angina be avoided?
Doctors recommend controlling the risk factors that contribute to
the underlying coronary artery disease, namely high blood pressure,
diabetes, cigarette smoking, high blood cholesterol levels, and
obesity.
How is angina treated?
Angina is usually controlled by medications that either increase
the supply of oxygen to the heart muscle by dilating coronary vessels,
or decrease demand for oxygen by slowing the heart rate or decreasing
the intensity of contraction. In some patients, however, medication
becomes insufficiently effective over time.
What happens when medication
fails to control angina?
Angioplasty (bypass surgery) is usually recommended if medication
fails to control angina or if the risk of heart attack is high.
What is an angiogram?
Angiograms are used to evaluate the condition of the coronary arteries
and nourishment of the heart muscle. A dye which can be imaged by
x-ray techniques is injected into the heart's blood vessels via
a catheter is inflated alongside the obstructing plaque deposits,
flattening them against the vessel wall to restore blood flow.
What are coronary arteries?
Surrounding the heart, these arteries provide the heart with a nourishing
supply of blood.
What is coronary artherosclerosis?
Every year one million Americans develop atherosclerosis, partial
or total blockage of arteries caused by deposits of plaque in and
on the walls of the vessels.
What is an electrocardiogram
(EKG)?
An electrocardiogram is a recording of the heart's electrical activity.
It is detected by electrodes attached to the skin, and recorded
in waves that are displayed graphically. The EKG provides information
on heart rate, rhythm, and function. EKG may also indicate the presence
of heart damage or inadequate blood and oxygen supply to the heart
muscle, and abnormalities of heart structure.
Peripheral Vascular
Disease
Symptoms
The most common symptom of PVD is painful cramping in the leg
or hip, particularly when walking. This occurs when there is insufficient
blood flowing to the leg muscles during activity. The pain usually
disappears with rest. Following are possible signs of PVD:
Leg or hip pain during walking
Numbness, tingling or weakness in the legs
Burning or aching pain in feet or toes when resting
Sore on leg or foot that wont heal
Cold legs or feet
Color change in skin of legs or feet
Loss of hair on legs
If you have ANY of the PVD symptoms or
risk factors, seek medical assessment immediately.
Who is at risk for
PVD?
Men are slightly more likely than women to have PVD. Those who are
at highest risk are:
Over 50 Smokers Diabetic Obesity Sedentary
High blood pressure High cholesterol
How is PVD treated?
Based on an examination and risk factors, you may need to modify
your diet, quit smoking and/or begin a regular exercise routine.
If your symptoms are more advanced, you may require medical treatment
such as:
Angioplasty: A tiny balloon is
inserted into a blood vessel through a tiny tube (catheter) and
moved to the site of the blockage. The balloon is then inflated
to open the artery. In some cases, a tiny metal cylinder (stent)
is inserted in the artery to keep it open.
Thrombolytic Therapy: If PVD is
caused by a blood clot, thrombolytic drugs, sometimes referred to
as clot-busting drugs, may be administered to dissolve
the blood clot and restore blood flow.
Thrombectomy: If PVD is caused
by a blood clot, a tiny balloon may be inserted into the affected
artery above the clot site. The balloon is inflated, then pulled
back, removing the clot in the process.
Bypass Graft: A healthy blood
vessel from another part of the body or an artificial artery is
used to create a detour around the blockage.
