Vitamin D: Crucial for healthy arteries?

Posted on: August 8, 2013   by  John Cannell, MD

Healthy arteries are like long balloons that expand and contract with blood pressure variations. They should not be rigid pipes that do not distend. The balloon-like quality of arteries is called distensibility, and it is measured by ultrasound. In addition, ultrasound measures abnormal growth (hypertrophy) of the main pumping chamber of the heart, the left ventricle.

Recently, Turkish researchers, led by Doctor Osman Kuloğlu and 10 colleagues, working under the supervision of Professor Murat Çaylı, all of the Adana Numune Training and Research Hospital in Turkey, measured both aortic distensibility and left ventricular hypertrophy together with 25(OH)D levels in 136 newly diagnosed diabetics. They also measured high sensitivity C reactive Protein (CRP), a measure of inflammation.

    Dr. Cannell,

    If I may quote from your above article:

    “In the meantime, there’s no reason for diabetic patients not to be sufficient in vitamin D.”

    I’m finding via my discussions with others that it is the term “sufficient” which requires better definition.

    For example, (we know) that the IOM defines vitamin D sufficiency to be 20 ng/ml.

    This is the level that many (many) many doctors now utilize when determining a patient’s vitamin D status.

    People I talk with will tell me: “Oh yes! My doctor did certainly TEST my vitamin D status, and I have a healthy level of 22 ng/ml.”

    (sigh)

    I’m sorry for being (so) repetitive, but in my opinion, to be expeditious change must come from within the medical community.

    Doctors must talk with colleagues. It is a must–a “walk your talk” kinda thing.

    I do my part…over and over and over again. For example: I just spent my lunch hour talking with a young Indian PhD here at my institution of employment. Our institution’s privately operated HMO found her to be insufficient in Vitamin D. She did not remember her level, but knowing where work I may only imagine just how low her level must be. She told me: “No worries, the HMO is treating me to increase my level to sufficiency (guess what # is used here for sufficiency??), and I am taking my D2 faithfully….”

    I’m sorry for being (so) repetitive, but in my opinion, to be expeditious change must come from within the medical community.

    (sigh)

    I’d like to add that the reason I mentioned that my young is from India, is because 80% (I think more like 99%) of Indians are deficient in D.
