In most cases, heart failure can be adequately treated and controlled, allowing you to continue to work full time for many years. Your particular situation will depend on the cause and severity of your heart failure, as well as the demands of your job. Your doctor may help you decide the appropriate level of work you can do. You may need to adjust your working hours or other strenuous activities. If you feel you are becoming less able to do your job, discuss this with your doctor in case a change of medication is needed, and/or with your employer to see if other work can be arranged.
