Other than giving your dog whatever medication your vet has prescribed, there isn't much else that can be done. CHF is a progressive disease. Some of the symptoms can be treated temporarily (such as if your dog develops fluid in the chest), but when your dog's heart completely fails, there is nothing that can be done whether you are at home or at the vet's or at work. Enjoy the time you have - which could be days or years.
There is nothing irresponsible about leaving your dog at home alone for a few hours. You have to keep living your life.
