Hello and thank you for using Chat Doctor. I carefully read your question and I understand your concern. You should not worry.I'll try to explain you something and give you my opinion. As you explain your father has a stent on a coronary artery. This means that the artery with a stenosis now should have normal blood flow. You should know that for the fist 6 months their is a risk for stent stenosis, so it is mandatory to take the medication and do regular control after 1,3 and 6 months. Normaly after stent intervention your father should be back to a normal live because this is why we intervene to have a normal life without chest pains or dyspnea. Feeling weak or tired might be related to several thinks like hypotension because of medication or his cardiac function, might be related to low heart rate or different pathologies like anemia or thyroid gland problems. About his medication copper does not cause such symptoms. Lasix might give electrolyte imbalance that might cause weakness. So, to find the real reason my opinion is that you should monitor his blood pressure and his heart rate during the day. Then it is necessary a full blood analyze to exclude anemia, thyroid problems or electrolyte imbalance. I will also suggest a cardiac echo to see cardiac function even though I suppose he was already done it. Hope I was helpful. Wish your father good health. Best regards.
