Systemic haemodynamic and coronary diameter and blood flow variables

  • Values are mean (SEM).

  • Low MgSO4 was at a dose of 0.02 mmol/min; high MgSO4 was at a dose of 0.2 mmol/min.

  • HR, heart rate; L-NMMA, NG-monomethy-L-arginine; MAP, mean arterial pressure.

  • 1-150 p < 0.001 v baseline;

  • 1-151 p < 0.01v low MgSO4;

  • 1-152 p < 0.05v low MgSO4;

  • 1-160 p < 0.05v baseline before L-NMMA;††p < 0.05v others except high MgSO4;

  • 1-153 p < 0.001 v others;

  • 1-154 p < 0.01v others.
