By adopting the FIND‐HF mnemonic (Fatigue, Increased water accumulation, Natriuretic peptide level testing, Dyspnoea) in a clinical consensus document by the Heart Failure Association of the European Society of Cardiology (ESC), healthcare professionals can attain a higher level of suspicion for HF and have a lower threshold for making biomarker measurements to detect HF and start early treatment with a sodium‐glucose cotransporter‐2 inhibitor (SGLT2‐inhibitor), if there are no contraindications and diuretics in case of congestion.15 This evidence concerns the gene SLC5A2 and hydrops fetalis.
