Q & A: Cardiac Drugs

By Stephen T. Sinatra, M.D., F.A.C.C., F.A.C.N., C.N.S., C.B.T.

**Q: If you have diabetes managed with medication (not insulin), high blood pressure also managed with medication, take Plavix blood thinner because you had a stroke, and take Prilosec for stomach issues, is it safe to take the D-ribose supplement?

A: The body makes D-ribose so it’s a safe ingredient to take. However, remember D-ribose can cause blood sugar levels to drop. You mention you are not using insulin, but for those who do, you may require less of it when supplementing with D-ribose. You can take D-ribose with a glass of fruit juice to offset any negative drop in blood sugars.

**Q: My dad has just been prescribed Coumadin after having a pace maker implanted. I am very concerned about this drug. Does the natural nattokinase work as a blood thinner just as well or better than Coumadin? I’m totally convinced that nutrition is key to optimal health, yet the doctors are telling my dad to stay away from all the great greens, pomegranate juice and literally everything concerning Vitamin K that is typically great for your diet. Is there a more natural approach through which he could totally relieve his dependence on Coumadin?

A: These are great questions. Since others have voiced related concerns (see below), we’ve decided to address them all in a separate article about Coumadin.

**Q: I have AF (Atrial Fibrillation) with two leaky heart valves. I want to wean myself off Warfarin (with my Dr’s help) and try nattokinase. Will nattokinase help the leaky valves alone with AF?

A: As mentioned above, we posted an entire article about Warfarin (Coumadin) in response to your question. You may also find this article about atrial fibrillation helpful.

*Q: I had a heart attack last summer, and my recovery has gone very well. I still take Lopressor and Cardizem, am back to work and feeling fine. But my wife thinks I’m different – that I’m moody and sometimes forgetful. Could the drugs be causing such changes?

I frequently hear similar comments from the spouses of my patients. To be frank, often someone who knows you well will notice subtle changes in your personality or behavior that you may not be aware of.

Beta-blockers, and particularly Lopressor, can cause moodiness and interfere with short-term memory. If patients are frustrated by their forgetfulness and mood swings, they may lose their tempers more than usual, adding to the stress on the family.

I recommend you ask your physician about trying other water-soluble beta-blockers such as Corgard or Atenolol. These do not cross the “blood-brain barrier,” so they do not affect your mental functioning. Some of my patients have had dramatic improvements in mood and memory because of this simple adjustment in medication.

    I read your article on the awesome foursome. Mom and I both take D-Ribose for heart health. Mom had a stroke/irregular heart beats about 2-3 years ago, she now has a pacemaker. Mom and I are on the keto diet and we do intermittent fasting. We have been following this lifestyle for about 5-6 months. Is D-Ribose keto friendly? Does it break a fast? D-Ribose lowers blood sugar, is it safe when we are already on a low carb diet?

    Hi Tuzi,
    D-ribose does not act like table sugar in the body. Rather then being used for a fuel, it is metabolized and used for the production of energy (ATP) in your cells. Ribose does contain calories, and it is known to cause an insulin reaction (which actually has the effect of lowering blood sugar). However, this slight insulin response may have an effect on ketone production. It may be a good idea if you take ribose, to monitor your ketone production and be sure it is not disrupting your state of ketosis.
