Q- What is atherosclerosis and angina
pectoris?
Ans- Angina
pectoris (also referred to angina) is chest pain / pressure that occur when the
blood and oxygen supply to the heart muscles cannot keep up with the needs of
the muscle. When coronary arteries are narrowed by more than 50% to 70%, the
arteries may not be able to increase the supply of blood to heart muscles
during exercise / other period of high demand for oxygen.
·
An insufficient supply of oxygen to the
heart muscle cause angina
·
Angina that occurs with exercise or
exertion is called exertional angina.
Diabetic patients, progressive decrease in blood flow to the heart may
occur without any pain or with just shortness of breath or unusually early
fatigue.
Q- What is unstable angina?
Ans- Exertional
angina usually feels like a pressure, heaviness, squeezing or aching across the
chest. This pain may travel to the neck, jaw arms back or even the teeth and
may be accompanied by shortness of breath, nausea or a cold sweat. Exertional
angina typically lasts from one to 15 min and relieved by rest or by placing a
tablet of NTG under tongue. Both resting and NTG decreases the heart muscle’s
demand for oxygen, this relieving angina. Angina also can occur at rest. Angina
at rest more commonly indicates that a coronary artery has narrowed to such a
critical degree that the heart is not receiving enough oxygen even at rest.
Angina at rest infrequently may be sued to spasm of a coronary artery (a
condition called Prinzmetal’s or variant angina.
Causes:- Classified as
one of the following two types-
·
Stable Angina
·
Unstable Angina
·
Coronary artery spasm Other Causes:-
·
Blockage of a coronary artery by blood
clot or by compression from something outside the artery
·
Inflammation or infection of coronary
arteries
Injury to one / more coronary arteries.

·
Pain may spread to the
shoulder, neck or arms
It may be located in upper abdomen, back or jaw.
Q- What are the
examination and Test?
· Ans- ECG
·
Chest x-ray
·
Blood test - cardiac
enzymes(CPKMB, TROP I)
·
Exercise stress test
·
Thallium stress test
·
Dobutamine echo
cardiogram stress test
Coronary angiogram
Q- What are the
treatments?
Ans- Treatment of angina
depend on the serenity of symptoms and result of test that are done to find the
underlying cause
Self care at home:-
·
Call immediate help
and intervention is the best chance for survival if someone is having heart
attack
·
Lie down in a
comfortable position with the head up
·
Chew a regular adult
aspirin or its equivalent or use of tablet NTG
·
Medical treatment –
Aspirin, clopidogrel, atorvastatin, beta blocker
·
Surgical Treatment
Regular follow up.
Q- What is the
prevention?
Ans- Best action is to
reduce risk factor early in life Although no one can escape aging, inherited
risk or gender, certain risk factors are in your control
·
Stop smoking and using
nicotine in any form
·
Control high blood
pressure
·
Lower blood fat
(through diet, exercise and medication)
·
Maintain a healthy
weight
·
Control diabetic and
blood sugar
Do not use stimulants such as cocaine and amphetamines.
