Considering you have heart failure (EJ <30%), and developed bronchitis on top of this, it's not surprising that you're experencing continued shortness of breath. I had bronchitis this past winter, and could never of imagined how rough it could be, much less with heart disease such as yours. My shortness of breath lingered as well, as did the crackling in the lungs and wheezing. You'll find this takes quite some time to pass, but I bet it will. Are you on a diuretic as well? If not, mention it to your doctor. My advice? Continue taking the medication as prescriped, live life, and I suspect the shortness of breath will sort its self out in the coming weeks. If not, remember the doctor is a phone call away.
