Key result
Peak diastolic filling rate during exercise radionuclide angiography fell to 1.7 end-diastolic counts/sec in patients with CAD, compared to an increase to 3.2 in those with normal arteries (p<0.001).
Why the study?
Does exercise radionuclide angiography detect coronary artery disease by measuring alterations in diastolic filling rate?
Cross-Sectional (n=85)

May support CAD detection via exercise radionuclide angiography diastolic filling; leaves open clinical adoption pending validation.
Poliner et al. (1984) conducted a cross-sectional in Coronary artery disease (n=85). Coronary artery disease vs. Normal coronary arteries was evaluated on Peak diastolic filling rate during exercise (end-diastolic counts/sec) (p=<0.001). Peak diastolic filling rate during exercise radionuclide angiography fell to 1.7 end-diastolic counts/sec in patients with CAD, compared to an increase to 3.2 in those with normal arteries (p<0.001).
