Key result
Nitrous oxide inhalation during cardiac catheterization did not significantly depress left ventricular performance and decreased determinants of myocardial oxygen demand.
Why the study?
Does nitrous oxide inhalation affect hemodynamics and left ventricular function in patients undergoing cardiac catheterization?
Population
30 patients undergoing cardiac catheterization, 24 of whom had coronary artery disease.

Supports hemodynamic safety of nitrous oxide in catheterization; leaves open randomized confirmation of oxygen-demand effects.
Does nitrous oxide inhalation affect hemodynamics and left ventricular function in patients undergoing cardiac catheterization?
Nitrous oxide inhalation during cardiac catheterization does not significantly depress left ventricular performance and may favorably decrease myocardial oxygen demand in patients with coronary heart disease.
Joshua Wynne (1980) studied Coronary artery disease / Patients undergoing cardiac catheterization (n=30). Nitrous oxide inhalation was evaluated on Hemodynamics and left ventricular function. Nitrous oxide inhalation during cardiac catheterization did not significantly depress left ventricular performance and decreased determinants of myocardial oxygen demand.
