One of the reasons, a person during initial stages of atherosclerotic coronary blood vessel may not show any symptoms of cardiac dysfunction because 1. Coronary blood vessels show marked reactive hyperemia. 2. Coronary blood vessels carry large amount oxygen which is not fully used by myocardium 3. The threshold for activation of the pain fibers associated with the Coronary blood vessels does not occur until they are fully compressed by the disease. 4. None of the above is correct

4. None of the above is correct
The coronary arteries supply blood, oxygen and nutrients to your heart. A buildup of plaque can narrow these arteries, decreasing blood flow to your heart. Eventually, the reduced blood flow may cause chest pain (angina), shortness of breath, or other coronary artery disease signs and symptoms.
