[|Human|] My husband had triple bypass and ever since he breathes hard like he is running a race and he isn t doing much. They have done all types of test on him and everything is good if not perfect.he has had problems with his back but nothing major could that be part of it?
[|AI|]  Hi, the breathlessness after a heart bypass surgery can be caused by several factors that we identify to be able to suggest a specific treatment for this problem. The main causes that should be investigated are:1- Lung diseases such as asthma triggered by physical exertion or the use of cardiovascular medications such as beta-blockers; pulmonary fibrosis triggered by use of medications such as amiodarone; sequela of previous pneumonia; emphysema and chronic bronchitis related to use current or previous smoking.2- Heart problems as incomplete myocardial revascularization; as a cardiac dysfunction caused by previous myocardial infarction or during surgery; as arrhythmias caused by physical exertion. Identified the cause of dyspnea can be guided and an appropriate treatment for resolving the problem. Hope I have answered your question. If you have any further questions I will be happy to help you. Wish you good health.
