[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Chest tightness, breathlessness, difficulty in walking etc. are suggestive of heart failure. Since he is already a cardiac patient (CABG), you should definitely consult cardiologist for his symptoms. Get done 2d echo and stress test (trade mill test). Angiography is also needed if stress test is positive. He may need diuretics and other cardiac supportive. Hope I have solved your query. I will be happy to help you further. Wishing good health to your father. Thanks.
