When you are having shortness of breath from dcm and heart failure is there anything you can do to help with this symptom?

Yes, typically. If your symptoms are due to becoming fluid overloaded, you may need your diuretic (water pill) adjusted. There are other medication changes which can also be made, depending on your blood pressure, etc. Sometimes people who are quite symptomatic from heart failure benefit from biventricular pacemakers. Also eecp can help some. If all measures fail, then may need to consider heart transplant.
