Rackley et al used the pulmonary artery occlusive pressure and cardiac index to classify a patient after an acute myocardial infarction.
NOTE: The same parameters but different decisions points are used in 06.08.11 (Hemodynamic Parameters and Risk after Myocardial Infarction).
Parameters:
(1) pulmonary artery occlusive pressure (PAOP) in mm Hg
(2) cardiac index in liters per minute per square meter
|
PAOP |
Cardiac Index |
Class |
|
< 20 mm Hg |
> 2.5 |
I |
|
< 20 mm Hg |
<= 2.5 |
II |
|
20 - 24 mm Hg |
> 2.5 |
III |
|
> 24 mm Hg |
> 2.5 |
IV |
|
> 24 mm Hg |
<= 2.5 |
V |
where:
• No class was listed for a PAOP of 20-24 mm Hg and cardiac index <= 2.5. I divided Class III in to IIIA and IIIB.

Management |
