Summary
The study describes the application of end-systolic pressure-volume relations (ESPVR) to assess cardiac contractility and pump function and how these quantities change with stress. Pressure-volume loops were constructed in ten anesthetized pigs, using both MRI and the conductance catheter to obtain left ventricular volume, combined with a special micromanometer-tip catheter for pressure measurement. The loops were obtained both during normal and reduced hemodynamic loading conditions, the latter acquired bij nitroprusside. Stress conditions were induced by dobutamine at an infusion rate of 10 μg/kg/min.
The ESPVR showed a parallel leftward shift (decreasing volume intercept) with dobutamine, indicating increased contractile state. The leftward shift was similar for the two methods: 6.9 ml for MRI and 7.4 ml for the conductance catheter method on the average. The slope of the ESPVR did not change significantly for either method. This finding is in agreement with results obtained by other investigators. It is concluded that, just as had been shown previously for the conductance method, pressure-volume loops and -relations may be obtained reliably using MRI for left ventricular volume measurement. This is promising for future applications of MRI to assess pump function during dobutamine-induced stress in patients diagnosed for left ventricular dysfunction.
