Hemodynamic classification in acute myocardial infarction.

Objective: Current mortality (M(1)) in hemodynamic subgroups of patients with acute myocardial infarction (AMI) was compared to that observed 30 years ago (M(0)), when hemodynamic classification was established. The prognostic value of oxyhemodynamic indexes in predicting M(1) for patients receiving right heart catheterization (RHC) was investigated.

Patients And Methods: We assigned 393 patients with AMI (mean age, 72 +/- 10 years) to four Killip categories.
