###Human: What can be done to manage breathing difficulty associated with heart block? ###Assistant: Hello. I have gone through an angiography report (attachment removed to protect patient identity). There are multiple blockages including a blockage in a left main coronary artery (LMCA), for which bypass is the best option. So, angioplasty is not possible and should undergo bypass. Also, other medical treatments according to the echo report must be continued. Even after bypass, he should regularly be on medicines and sugar, BP should be adequately controlled. Otherwise, there is a risk of development of new blockages. So, overall needs an early bypass and regular medical therapy.
