Key result
Volume loading in patients with severe right ventricular infarction did not significantly improve cardiac output (2.4 vs 2.3 l/min/m2, P=ns) or stroke volume, but decreased RV ejection fraction.
Why the study?
Does intravenous fluid loading improve cardiac output and hemodynamics in patients with severe right ventricular infarction?
Population
11 consecutive patients with severe right ventricular infarction complicated by low cardiac output syndrome.

Loading...
May not support volume loading in severe RV infarction; leaves open optimal fluid strategies pending randomized data.

Does intravenous fluid loading improve cardiac output and hemodynamics in patients with severe right ventricular infarction?
Absolute Event Rate: 2.4% vs 2.3%
p-value: p=ns
Intravenous volume loading in severe right ventricular infarction increases filling pressures and right ventricular volumes but fails to improve stroke volume or cardiac output, challenging its routine use in this setting.
SlNIORAKIS et al. (1994) conducted an observational in Severe right ventricular infarction (RVMI) (n=11). Volume loading vs. Baseline (before volume loading) was evaluated on Cardiac output (l/min/m2) (p=ns). Volume loading in patients with severe right ventricular infarction did not significantly improve cardiac output (2.4 vs 2.3 l/min/m2, P=ns) or stroke volume, but decreased RV ejection fraction.
