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).
(1) pulmonary artery occlusive pressure (PAOP) in mm Hg
(2) cardiac index in liters per minute per square meter
< 20 mm Hg
20 - 24 mm Hg
> 24 mm Hg
• 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.
treat aggressively if recurrent chest pain or hypertension, else watch
treat pulmonary edema and hypoxemia
