Hi there, Thanks for writing in. I am a qualified and certified cardiologist. I am afraid you will have to meet the doctor or group who had done the stent implantation six months ago for it is them who know the technical details and can advise you about the revised medicine schedule under the present circumstances. Moreover, diarrhea can be drug related in any case drugs will have to be re adjusted as per the essential requirement, to give one example the blood thinners can be safely reduced to a predetermined level after six months here blood thinners can turn vomiting due to whatever the cause into blood in vomit (Hematemesis) hence the need to meet them. Secondly, her diabetes control is or paramount importance. Thirdly, diabetic complications like Diabetic Gastroparesis (absence of proper movement of gut due to diabetes) can be responsible for vomiting. Health care magic does not prescribe medicines it guides the patient about the right way to go about an illness. Good Luck.
