Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. I m afraid your question is too vague to be answered. If you d like to receive a credible answer you should clarify the following: - bad heart : it could be a lot of things for example atrial fibrilllation (fits well with your history of stroke), coronary heart disease, heart failure, pericarditis, etc. - what drugs: you haven t mentioned either the names or the active ingredients of the drugs you re using and the dosage. This is very important! - messing me up : this is not a very helpful description, I m afraid. Please describe your symptoms in detail. One final note is this: the most appropriate person to decide about a patient s treatment is the patient s doctor. This is the only doctor that knows the patient s history in detail. Some side effects can be attributed to drugs but an experienced doctor can tell when a patient requires further investigation or not. So in conclusion, I don t have enough data to comment on the essence of your case. You can send another question will more details if you d like. Until then I d suggest you to follow your doctor s advice. Hope I have answered your query. Let me know if I can assist you further.
