predictably with exertion or stress and is relieved by rest or

nitroglycerin.
Characteristics: Usually lasts a few minutes. Caused by a

temporary decrease in blood flow to the heart muscle, often

due to coronary artery disease. Symptoms are consistent and
can be anticipated based on activity levels.
Unstable Angina Ans: Description: This type is more
unpredictable and can occur at rest or with minimal exertion.
It may last longer and is not relieved by rest or nitroglycerin.
Characteristics: Considered a medical emergency as it can
precede a heart attack. Symptoms may vary in intensity and
duration. Indicates a significant increase in the risk of
myocardial infarction due to unstable plaque in the coronary
arteries.
Electrocardiogram (ECG or EKG) Ans: Purpose: Measures the
electrical activity of the heart to identify arrhythmias, heart
attacks, and other cardiac conditions.
Procedure: Electrodes are placed on the skin to record the
heart's electrical signals.
, 2
Echocardiogram Ans: Purpose: Uses ultrasound waves to
create images of the heart's structure and function, assessing
heart size, shape, and motion.
Procedure: A transducer is placed on the chest to send and
receive sound waves.
Stress Test Ans: Purpose: Evaluates how the heart performs
under physical stress, often used to diagnose coronary artery
disease.

Procedure: The patient exercises on a treadmill or stationary
bike while heart rate and rhythm are monitored, or medication
Guru01 - Stuvia
is administered to simulate exercise.
Expert
Cardiac Catheterization Ans: Purpose: Involves threading a
catheter through blood vessels to the heart to diagnose and
treat certain heart conditions, such as blockages.
Procedure: A contrast dye is injected to visualize the coronary
arteries using X-ray imaging.
Blood Tests Ans: Purpose: Measures levels of certain
substances in the blood that can indicate heart problems, such
as cardiac troponin (which rises during a heart attack) and
brain natriuretic peptide (BNP, which indicates heart failure).
Procedure: A blood sample is taken and analyzed in a
laboratory.
Chest X-ray Ans: Purpose: Provides images of the heart,
lungs, and blood vessels to check for heart enlargement or
fluid buildup.
