Once congestive heart failure sets in, some patients live for many more years, while others pass away within a matter of months, according to Caring.com. The differences comes from the severity of the disease and the therapeutic treatments that patients use to make their lives longer and higher in quality.
When congestive heart failure, or CHF, is mild or moderate, the heart pumps less blood with each beat, and some blood goes back in as the veins back up. This leads to congestion in the heart tissue. However, medications allow these patients to remain fairly active and to live for many more years. Once the CHF becomes severe and medications no longer help, life expectancy shortens considerably, as patients enter the hospital and face a poor prognosis for recovery, notes Caring.com
