Hello sir, your symptoms fit in classic angina and the breathlessness is due to the heart. Now your doctor wanted to optimise your medication so as to make sure that your heart gets enough blood supply and limit in symptoms occur. Prolomet, Nikoran, ranolaz, imdur, myonit Sr and others , are to help relive the symptoms, telmisartan is for blood pressure, lacilactone to remove extra fluid maybe because your heart pumping has gone low. Sir many meds are similar to each other and different brand names, so I would like that you review it with your doctor, so he can cut down on unnecessary ones, as so much pill burden will be bad for your stomach. Lastly if symptoms persist think about revasularisation that is either angioplasty or reoccurring do bypass. I would be able to help you better If you can send the angiogram and the complete prescription with the med list and when you take which medicine. Hoping I could help Regards Dr. Priyank Mody
