Some medications cause discomforts and are very often overlooked by Doctors. A good friend of mine was on Aspirin, Clopidogrel, Bisoprolol and Lipitor. For 2 years he went to his Doctor complaining of chest pains and they had no explanation. They suspected "MAYBE" artery spasm or small vessel disease, but they were really guesses. Just before Christmas just gone, he had enough and stopped taking all his medications. After three days he started to improve and felt much better. He started to do a lot of gardening, walking to the shops and had no pains or shortness of breath. He tested this for a month and his condition improved a lot. He then started all his meds again and within a week all his problems returned. He is now trying different brands of medications with his Doctor to see which one/s are causing the issues.
I am in no way suggesting that you stop any meds, but I am saying it is a strong possibility. Clopidogrel (plavix) is a medication given after stenting and this causes shortness of breath with me. I had to endure it for a year and when the medication was stopped, it was like I had a new pair of lungs. ALL medications have side effects but at different severities and are often overlooked.
Hello and hope you are doing well.
If repeated stenting and medications are not helping with your symptoms, then CABG, coronary artery bypass grafting, is the next choice. This is however contraindicated in the absence of an open major artery 1 mm or more in diameter beyond the obstructing lesion; the absence of viable myocardium in the area supplied by the stenosed artery; and coexisting severe noncardiac conditions with a poor prognosis. So, please discuss with your doctor about the contraindications for CABG.
Hope this helped and do keep us posted.
