Explanation:
Detailed explanation-1: -Conclusions-Resting coronary artery flow velocity is inversely related to the ratio of lumen area to regional left ventricular mass. Higher resting velocities are found when insufficient lumen size exists for the distal myocardial bed, as occurs with diffuse mild or moderate coronary atherosclerosis.
Detailed explanation-2: -Velocity of blood in the vasculature has an inverse relationship with cross-sectional area (volumetric flow rate (Q) = flow velocity (v) x cross-sectional area (A)). As the cross-sectional area increases, velocity decreases.
