Question: 1 / 400

What might normal ABI results imply about a person's vascular health?

Presence of severe vascular issues

Normal blood flow and healthy arteries

Normal Ankle-Brachial Index (ABI) results indicate that there is a healthy ratio of blood pressure in the ankle compared to the arm, which suggests adequate blood flow to the lower extremities. This is indicative of well-functioning arteries, meaning there are no significant blockages or peripheral artery disease, both of which can lead to diminished blood flow and various vascular issues.

In context, lower ABI values could suggest the presence of vascular issues, necessitating further cardiovascular assessment, or indicate an increased risk for claudication (pain caused by insufficient blood flow during exercise). However, normal ABI findings specifically mean that vascular health is intact, affirming that the person has normal blood flow and healthy arteries. This conclusion stems from the fact that ABI is a reliable non-invasive test used to evaluate peripheral artery health.
