Q

What are the main differences between stable and unstable angina?

A

In STABLE angina, pain is experienced on exertion with relief from GTN
In UNSTABLE angina, pain is experienced at rest and is not necessarily relieved by nitrate use.

Q

What is AF?

A

It is an arrhythmia wherein there is an irregularly irregular beating of the heart. It leads to inefficient ventricular filling and therefore reduced cardiac output.

Q

What constitutes heart failure?

A

It is the inability of the heart to pump efficiently. This means that there can either be systolic dysfunction (affecting cardiac output), or diastolic dysfunction (improper filling of the atria or ventricles).
