NPPB and chronic obstructive pulmonary disease: NT-proBNP was recorded in only 38.1% of HF patients, although it isrecommended in the HF guidelines as a test to assist GPs to rule out HF.Especially in elderly patients with comorbidities, such as COPD, HF patients maybe overdiagnosed due to overlap in symptoms and signs (Brenner etal., 2013).
