Implication

Chest radiography inaccurately estimates wedge pressure in acute MI; leaves open its hemodynamic utility and requires prospective validation.

Structured PICO

Does the chest film accurately predict hemodynamic status (wedge pressure) in patients with acute myocardial infarction?

P
Population
86 patients with acute myocardial infarction
I
Intervention
Chest roentgenogram (film)
C
Comparator
Hemodynamic parameters (wedge pressure) obtained within 2 hours of the roentgenogram
O
Outcome
Correlation between radiographic appearance of pulmonary vasculature and wedge pressure levelssurrogate

The chest roentgenogram has significant limitations in accurately predicting the hemodynamic status (wedge pressure) of patients with acute myocardial infarction, often demonstrating diagnostic or therapeutic phase lags.
