The life expectancy of an elderly person with congestive heart failure depends on the severity of the disease, states Cleveland Clinic. Almost half of patients with serious symptoms pass within just 12 months, and others who have less severe symptoms may live another six years.
There isn't an average life expectancy for congestive heart failure patients because the recorded data is too varied. The number of years a patient lives relies on the stage that the disease is in, explains Cleveland Clinic. There are treatments for this condition, but they only treat the symptoms in the short-term. As the disease progresses, it becomes more difficult to find treatment options.
