As of 2013, only about 1 in 3 patients diagnosed with heart failure survives for longer than five years, according to the American Heart Association. However, overall survival rates are influenced by older patients whose health is worse than in previous years.
Despite the relatively poor prognosis for heart failure patients, their overall survival rate improved by 45 percent in the decade between 1994 and 2004, as reported by the American Heart Association. Some of the improvement is likely due to the increased use of aspirin, beta blockers and statin drugs in patients diagnosed with heart failure. However, the AHA study found that patients with heart failure were more likely to have other comorbid conditions such as kidney disease and high blood pressure.
