Why the study?
It was unknown whether the pattern of lung function impairment differs for the prediction of sudden cardiac death versus non-fatal coronary events.
Is low lung function associated with an increased risk of sudden cardiac death compared to non-fatal coronary events in middle-aged subjects?
Population
28 584 middle-aged subjects without history of CE from the Malmo Preventive Project
Comparison
Measures of lung function assessed at baseline spirometry
Design
Prospective population-based cohort study

May refine post-CE SCD risk stratification; leaves open whether spirometry improves models in prospective validation.
Is low lung function associated with an increased risk of sudden cardiac death compared to non-fatal coronary events in middle-aged subjects?
Low FEV1 is a strong predictor of future sudden cardiac death, suggesting spirometry could aid in global cardiovascular risk assessment.
