Episode notes
Definition And Diagnostic Importance
- Acute decompensated heart failure includes impaired filling or reduced ejection fraction and is common in the ED.
- Missing the diagnosis may increase mortality, so clinical suspicion matters.
History And Exam Predictors
- Certain history and exam findings strongly increase the probability of heart failure, including prior CHF, PND, orthopnea, and DOE.
- An S3 had a very high positive likelihood ratio, followed by JVD and rales.
Always Get An ECG
- Always obtain an ECG to assess for acute myocardial infarction in dyspneic patients.
- A normal ECG makes left ventricular systolic dysfunction unlikely, with a high negative predictive value.
