This often indicates blocked arteries.

Low blood flow during both rest and exercise indicates that part of the heart is not getting enough blood, according to Mayo Clinic. This may be due to a previous heart attack or to severe coronary artery disease. The final possible result from a nuclear stress test may show no flow to areas of the heart. In this case, it is due to tissue damage from a previous heart attack. Those who do not have enough blood pumping through their heart may need to undergo treatment known as coronary angiography to further diagnose the condition.
