I believe the Spiro.. is a potassium sparing diuretic. Still need to have blood test with that to see your body is not holding too much potassium. I have seen it suggested (and told by Dr. Mildred Seelig, who was the world's leading magnesium specialist) that people taking clacium channel blockers should not be taking calcium supplements. They kind of contradict each other. You don't want to block the calcium channels (somewhat) while adding more to the system. Even though you are young (same age as I am)...you might what to consult a "certified geriactric pharmacist" on your medications. You can find a list of them in your area by looking them up. They have a considerable amount more of education to obtain this certification. They are a real doctor, with their degree in pharmacy. They really helped my mother, and also did agree that the doubling of her diltiazem along with her statin was the cause of her condition worsening. I am at least skilled in observation testing, and the cause and effect came in the same time frame. The beta blockers are known to raise blood sugars (and can raise trigs)....however coreg (beta blocker) has been shown not to raise blood sugars. Spectracell in Houston can do the intracellular magnesium test, as well as a complete intracellular panel, including cholesterol with is broken down much more than the normal cholesterol panels. Insurance will cover these tests. You doctore writes the prescription for the tests and you local lab draws the blood. The samples are then sent to spectracell. The test also included homocystine, lp(a), fibrogen, CoQ10, and many other things. Still stains in women are NOT shown to increase longevity. I don't care where other people get their information, but the Statin STudy at UCSD (and NIH (government) funded study) has combed through every statin trial and study. This is their conclusion. It is from the data submitted to form all of the touted "benefits" that the drug companies claim. While it is true in women there were less cardio events, there were more cancer deaths that canceled out the the longevity factor. In this information also it showed that people over 65 had increased longevity with higher cholesterol levels....this included LDL. You might remember that a drug company was about to go for final FDA approval for a medication that raised HDL....well that blew up in their face because of the additional heart attacks it caused. Messing with cholesterol with medication is a risky business... It is a fine balance in your body and requires many factors. Just lowering (or raising) cholesterol with medication causes a disruption in that pathway. Did you ever notice what road constrution does to the flow of traffic? You body is much like that, but a highway of chemical reactions. You might want to up the Coq10 a bit. ALso make sure you are taking fish oil for the omega 3's. Good luck.... oh one more thing, if your cardio guy ever tries to give you amiodarone for your heart... just note that the FDA has issued a warning saying it is to be the medication of ABSOLUTE LAST RESORT. IT is REQUIRED by law that the doctor give you this information in writting. It also depletes Coq10. Another one of those helpful drugs that depletes a required substance in your body...and which doctors pay no attention to.
