What does borderline peripheral vascular disease on ankle brachial index test mean? it was 0.93. i had normal calcium score/cta.

Probably nothing: Normally the ankle/brachial artery index is greater than 1.0, but you have to look at the results in context. First question, why did you get the test? Second question, do you have any symptoms, such as leg pain during exercise? Third question, any risk factors, e.g. trauma, diabetes? Normally, at 19 years of age, it is highly improbable that this is meaningful.

Below: There may be mild plaque in the arteries supplying blood to your legs. In most labs, 0.9-1.0 are actually considered normal. It is extremely you actually have peripheral disease at your age. Talk to the provider that ordered the test.

PVD, PAD: i would not call an ABI of .93 borderline PVD (peripheral vascular disease). It is normal. If you divide the arm blood pressure by the ankle pressure the number should be 1.0. Meaning the arm and ankle should have the same blood pressure. ABI's of .5 suggest occlusive disease or a blockage somewhere in the leg or calf. Again, an ABI of 0.93 is normal
