a Transthoracic echocardiography parameters from eight rats under baseline conditions and stimulation with adenosine and dobutamine: ejection fraction (EF), end-diastolic volume (EDV), and end-systolic volume (ESV). b Visualisation of the following pulsed wave Doppler-derived blood flow parameters in eight rats: diastolic peak velocity (DPV), velocity time integral (VTI), and coronary flow velocity reserve (CFVR). c Graphs showing the effect of adenosine and dobutamine on myocardial perfusion measured by myocardial contrast echocardiography (MCE) in eight rats using the following parameters: normalised peak enhancement (normalised PE), normalised wash-in rate (normalised WIR), and normalised area under the curve (normalised AUC). * p < 0.05; ** p < 0.01; ***p <0.001. Values are shown as the mean ± standard deviation
