Lung function and airway obstruction: associations with circulating markers of cardiac function and incident heart failure in older men - The British Regional Heart Study

This study examined to what extent lung function and airway obstruction was associated with cardiac markers (ie N-terminal probrain natriuretic peptide and cardiac troponin T) and the risk of incident heart failure in 3242 British males aged 60–79 years. Lung function testing (FEV1, FVC) was undertaken using a Vitalograph COMPACT spirometer.
