Prevalence figures compiled from the following international registries of patients presenting to hospital with acute heart failure: ADHERE,[2] OPTIMIZE,[3] EFICA,[18] ATTEND,[19] IMPACT-HF,[20] and EHFSII.[21] Sensitivities and specificities adapted from a separate meta-analysis by Wang et al.[34] – a synthesis of data from 22 observational series of patients presenting with undifferentiated dyspnoea. COPD = chronic obstructive pulmonary disease.
