Do modified methods for assessing the end-systolic pressure-volume relationship correlate with Sagawa's model of time-varying elastance in human patients?
This study aimed to validate simplified methods for assessing left ventricular end-systolic pressure-volume relationships against Sagawa's time-varying elastance model using simultaneous pressure and radionuclide volume measurements.
McKay et al. (1986) studied this question.
