I feel that if I were to wait for my husband's doctors to recommend anything natural, he would be being deprived of considerable help. I have frequently read about the usefulness of a homocysteine level test at predicting the liklihood of a heart attack and, if the test is positive, the value of supplementing with vitamins B6, B12, and folic acid. Many thanks for this helpful service. Prinzmetal's angina is due to coronary artery spasm in a person with normal coronary arteries. It may be diagnosed in the cath lab by injecting the coronary arteries with ergotomine to see if spasm can be precipitated.
Treatment is with a type of medication called calcium channel blockers.
By definition you husband does not have Prinzmetal's angina because he has coronary artery blockages. However, calcium channel blockers may provide some benefit if your husband has failed other medications. I have never been able to have a meaningful conversation with a doctor about things like COQ10, vitamin E, vitamin B6,etc. I feel that if I were to wait for my husband's doctors to recommend anything natural, he would be being deprived of considerable help. This is well established medical fact but unfortunately still many doctors do not spend significant time on prevention.
