Hi Sir, I am 42 years old male. As a routine medical check-up, I was diagnosed positive in TMT test. As a follow up of this I had undergone Coronary Angiography, 15 days ago, which indicated multiple blockages. Even though blockages are serious in nature, more than 70%, some are 80%, no symptom of chest pain I ever felt. I am a heavy smoker. Now that I quit smoking after Angiography, my concern is whether to fix these blockages by CABG, suggested by Cardiologist. Later, on the advise of another Cardiologist, I had undergone Stress Thallium test which indicates Normal study, no indication of ischemic heart disease. With these contrasting results I am puzzled. Now my question is whether to treat blockages by medication or bypass surgery. Kindly advise.
