A clinical and biochemical critical pathway for the evaluation of patients with suspected acute congestive heart failure: The proBNP Investigation of Dyspnea in the Emergency Department (PRIDE) algorithm
Dyspnea is a primary clinical manifestation of acute congestive heart failure (CHF) among patients presenting to the emergency department (ED). Unfortunately, other critical illnesses, including acute coronary syndromes, pulmonary embolism, chronic obstructive pulmonary disease, and pneumonia, may present with clinical symptoms and signs similar to acute CHF. N-terminal pro-brain natriuretic peptide (NT-proBNP) has proven to be a powerful tool in the diagnostic assessment of dyspnea as a result of its ability to confirm or exclude the presence of acute CHF. However, many of the disorders that mimic acute CHF may result in elevated NT-proBNP levels as well. Results from the ProBNP Investigation of Dyspnea in the Emergency Department (PRIDE) study recently demonstrated that a strategy integrating NT-proBNP testing into routine clinical assessment demonstrated a better diagnostic yield than each strategy used in isolation. We present a diagnostic algorithm integrating NT-proBNP testing with clinical assessment for use in routine clinical practice.
