Are the lungs or heart causing shortness of breath and no energy?

My husband has been diagnosed with Bronchiostatis and also Pseudonomas which was treated several times with antibiotics in the hospital and at home. The coughing stopped after that but now it is back again and sounds very congested again. He has given 3 sputum samples but evidently there was something wrong with them or a miscommunication between doc and lab. He will be 80 in Feb and also has congestive heart failure and is very tired most of the time and experiencing shortness of breath. He gets an infusion 1/x /mo. for CLL and then gets a little more energy. He just saw the cardiologist who said He is not sure if the no energy and shortness of breath is caused by his lungs or his heart. He has ordered additional heart tests and we are trying to get a sputum sample. Do any of you with brochiostatis and possible pseudomonas have any shortness of breath or tiredness? I feel like we are just spinning our wheels here and my poor husband is not getting any better. Thank you so much for your help. Miriam p.s. he calls himself "a medical wonder" 🤣
