ISCHEMIC HEART DISEASE: PART 1
What is ischemia?
A condition in which blood flow (and thus O2) is restricted or reduced in a part of the body.
What is hypoxemia?
Low O2 content in the blood = Low O2 Sats!!
What is hypoxia?
A condition in which the body or a region of the body is deprived of adequate O2 supply at the tissue level
Does ischemia result in hypoxemia or hypoxia?
Hypoxia
_____ ________ _________ is an umbrella term for a range of symptoms associated with sudden, reduced blood flow to the heart i.e. cardiac ischemia.

Yes
IHD includes what 3 things?
- heart attacks
- angina (stable and unstable)
- heart failure and arrhythmias
What is angina?
