Know the difference between central and tissue perfusion.
When you think tissues – think specific places.
Central is generalized – cardiac output.
First sign of pumping problem is lungs. Left side failure is first right side is later in life.
Exemplars
- Angina (supply of O2 is less than demand)
Stable: relieve with rest and nitro
Unstable: unable to relieve with rest and nitro; its changing. We worry about this.
- Coronary Artery Disease – damage to arteries of heart
- Atherosclerosis: plaque (hardening)
Hyperlipidemia -
- Myocardial Infarction: tissue death; heart attack
STEMI: S-T seg is elevated
NonSTEMI: S-T seg isn’t elevated
- Hypertension:
- Congenital Heart defects: branch down into 4 main categories; two main branches: cyanotic and
non-cyanotic
- Heart Failure:

least CCS class III severity).
