Key result
Intracoronary Doppler measurements revealed no significant difference in coronary flow reserve between proximal, mid, and distal segments of normal LAD arteries (2.3 vs 2.3 vs 2.3, p=0.95).

Distal CFR measurements may suffice in normal LAD; leaves open segment relevance in diseased vessels.
Observational (n=9)
Does coronary flow reserve differ between proximal, mid, and distal segments of normal left anterior descending coronary arteries?
Absolute Event Rate: 2.3% vs 2.3%
p-value: p=0.95
Coronary flow reserve is consistent across proximal, mid, and distal segments of normal LAD arteries, validating the use of distal measurements for assessing microcirculatory function.
Park et al. (2000) conducted an observational in Normal Left Anterior Descending Coronary Arteries (n=9). Intracoronary Doppler guide wire with adenosine vs. Proximal vs. mid vs. distal segments was evaluated on Coronary flow reserve (CFR) (p=0.95). Intracoronary Doppler measurements revealed no significant difference in coronary flow reserve between proximal, mid, and distal segments of normal LAD arteries (2.3 vs 2.3 vs 2.3, p=0.95).
