Lung function over the life cycle

PEOPLE have often discussed the virtues of lung function in the prediction of survival at all ages.

In infants born extremely prematurely, difficult-to-control asthma, smoking-related lung disease and chronic obstructive pulmonary disease (COPD), much emphasis has been placed on markers of airway obstruction obtained through spirometry. 

Of primary importance are measures of expiratory airflow, such as the forced expiratory volume in the first second of expiration (FEV1).

Moreover, there are many studies which have shown relationships between increased cardiovascular risk and a lower FEV1. 

Some recent epidemiological work has cast some doubt on this for otherwise healthy people with no history or symptoms of lung disease, which has suggested that it is the forced vital capacity (FVC) that may independently predict a person’s longevity.

Data was gathered from the limited access data set of the Atherosclerosis
