<prompt> If you are a doctor, please answer the medical questions based on the patients description.My 69 year old wife has been diagnosed with Stage 3 CKD and hypertension, as well as coronary blockage 70-80 which will likely require a stint to avoid a heart attack. The doctor explained that the stint would require a regimen of aspirin and Plavix sic? for an extended period. Our understanding is that aspirin is quite harmful to kidneys, so we re on the horns of a dilemma. Do the risks of heart problems outweigh those of dialysis, or can she survive for an extended period on the aspirinPlavix without significant additional kidney damage?  <response>: Hello, aspirin for heart problem is taken in the dose of 62-150 mg per day which doesnt have adverse effect on kidney it is rather far higher dose where aspirin is taken as a painkiller, and Plavix is similar blood thinner given at 75 mg a day which is removed from the body 50 by liver and 50 by kidney and so no dose modification is needed for the kidney disease. Both are beneficial for the heart and should be taken without doubt. Regards Chat Doctor.
