Hello, Thanks for posting your query on Chat Doctor ...* Brief Answer:it seems that your father needs to do CABG(coronary artery bypass grafting).*Explanation: My opinion is that multiple coronary vessel disease is an indication to do coronary bypass grafting, percutaneous coronary intervention in your father condition is debatable and may be non-beneficial to his condition, on the other hand, CABG would improve morbidity and mortality. I suggest my patients the following : consult a cardiothoracic surgeon about your fathers condition and adhere to antiischemic medications information provided by you is not sufficient to provide a good opinion. If someone comes to me with this condition I would ask them about other comorbidities and results of any other investigations you have done to your father.*Conclusion: I suggest you consult a cardiothoracic surgeon and stick to your medications low salt in diet and If you have any further questions I will be happy to help, If not, you can close the discussion and rate the answer. Wish your father good health.
