Abstract
Heart failure is a complex clinical syndrome that presents a difficult diagnostic challenge for practitioners. Index of suspicion for heart failure and a clear understanding of the condition are crucial for timely and correct diagnosis and prompt provision of effective treatment.
Key Points
- Heart failure (HF) is categorised as HF with reduced ejection fraction (formerly known as systolic HF) or HF with preserved ejection fraction (formerly known as diastolic HF).
- HF is diagnosed clinically but needs to be confirmed with further testing.
- Correct and timely diagnosis is important, as prompt treatment can save lives and improve quality of life.
- An echocardiogram is the most important investigation in HF; it will confirm the diagnosis and inform further management strategies.
- In patients for whom the diagnosis is unclear, biomarker analysis with B-type natriuretic peptide (BNP) or N-terminal pro-BNP can be useful.
