Reduced lung function, measured by forced expiratory volume in one second, is linked to a higher risk of death from cerebrovascular disease, independent of other risk factors.

Area of Science:

  • Epidemiology
  • Pulmonary Medicine
  • Neurology

Background:

  • Cerebrovascular disease poses a significant public health challenge.
  • Ventilatory function is a key indicator of overall physiological health.
  • The relationship between lung function and stroke mortality requires further investigation.

Purpose of the Study:

  • To examine the association between ventilatory function and subsequent mortality from cerebrovascular disease.
  • To determine if impaired lung function predicts stroke risk.

Main Methods:

  • Prospective longitudinal study of 18,403 male civil servants aged 40-64.
  • Follow-up for 18 years to record cerebrovascular disease mortality.
  • Analysis of forced expiratory volume in one second (FEV1) as a measure of ventilatory function.

Main Results:

  • Men with lower forced expiratory volume in one second (<3.0 L) had nearly double the risk of death from cerebrovascular disease compared to those with higher FEV1 (≥3.5 L).
  • This association remained significant after adjusting for age, systolic blood pressure, and other potential confounders including smoking and employment grade.
  • The risk was evident across all systolic blood pressure tertiles.

Conclusions:

  • Impaired ventilatory function is an independent predictor of cerebrovascular disease mortality.
  • Lung function measurements may aid in identifying individuals at higher risk for stroke.
  • Shared underlying causes may link impaired lung function and stroke.
