Heart failure constitutes a major public health concern in the United States and is one of the leading causes of hospitalization, readmission, and death. Due to an aging U.S. population, it is estimated that the prevalence of heart failure will increase by 25% over the coming decades, affecting approximately 3.5% of the population by the year 2030. The ability to discriminate patients admitted with acute heart failure syndromes who are at increased risk for poor post-hospitalization outcomes is thus critical to guide therapeutic decision making for healthcare providers. This review paper will discuss clinical, hemodynamic, as well as biochemical markers that have been demonstrated to predict post-discharge outcomes among patients hospitalized with acute heart failure.
