Implication
May inform volume targets in acute right ventricular infarction; leaves open need for randomized confirmation of optimal filling pressures.
Structured PICO
What is the optimal right ventricular filling pressure to maximize right ventricular stroke work index in patients with acute right ventricular infarction?
P
Population
41 patients who fulfilled the diagnostic electrocardiographic and haemodynamic criteria of acute right ventricular infarction
I
Intervention
Haemodynamic monitoring during volume loading and intravenous glyceryl trinitrate infusion to alter right atrial pressure
O
Outcome
Right ventricular stroke work index, cardiac index, and stroke indexsurrogate
In patients with acute right ventricular infarction, maintaining a mean right atrial pressure of 10-14 mm Hg optimizes right ventricular stroke work and cardiac index.
