A newly designed non-invasive Doppler analysis of femoral arterial pulses was compared to cardiac 99mTc radionuclide ventriculographies (RNV) in 22 consecutive patients (mean age: 51.6 y; 17 male). 15 patients had proven or suspected coronary artery disease, 4 had orthotopic cardiac transplantation and 3 were under antimalignant chemotherapy. The patients underwent simultaneous RNV and 4 MHz femoral arterial Doppler in a stress protocol. Postexertional Doppler values (peak velocity, mean velocity, diastolic velocity and acceleration) showed significant correlations to RNV parameters of systolic cardiac function at rest and post exercise. The best correlation was seen between cardiac output and mean velocity or peak velocity of femoral arterial pulses (R = 0.822, p < 0.001 and R = 0.732, p < 0.001 respectively). This non-invasive Doppler test should be considered as a valuable supplement to routine exercise protocol to analyse systolic left ventricular function. J Clin Basic Cardiol 2000; 3: 59-60.
