Emergency department management of patients with right heart failure.

ABSTRACT

Right heart failure (RHF) can result from many cardiac, pulmonary, and systemic pathologies. Common causes of RHF include pulmonary embolism, left heart failure, congenital heart disease, chronic lung disease, acute myocardial infarction, infiltrative disease, infectious disease, and valvular abnormalities. Acute and chronic RHF confer a high risk for morbidity and mortality in the acute care setting, and interventions commonly used in emergency care can prompt acute decompensation if the RHF is not recognized. The severity of presentation may range from compensated clinically silent cardiovascular dysfunction to venous congestion, multiorgan failure, and circulatory collapse. This review describes the pathophysiology of right heart failure and offers an evidence-based approach to the diagnosis, management, and disposition of both acute and chronic RHF.
