Lung Measures and risk of incident Atrial Fibrillation in the Multi-Ethnic Study of Atherosclerosis
| Model 1 | Model 2 | |
|---|---|---|
| Variable | Hazard ratio (95% confidence interval) | |
| FEV1 per 500ml | 1.25 (1.12–1.36) | 1.21 (1.0–1.36) |
| FVC per 500ml | 1.20 (1.08–1.31) | 1.19 (1.02–1.33) |
| FEV1/FVC ratio | 1.65 (0.06–2.02) | 1.51 (0.05–4.9) |
| Percent emphysema (log) | 0.95 (0.83–1.08) | 0.96 (0.84–1.10) |
| Percent predicted FEV1 | 1.02 (1.01–1.03) | 1.01 (1.00–1.02) |
| Percent predicted FVC | 1.02 (1.01–1.03) | 1.01 (1.00–1.03) |
| Percent predicted FEV1/FVC ratio | 1.10 (1.00–1.02) | 1.01 (0.99–1.02) |
FEV1: Forced expiratory volume in 1 second, FVC: Forced vital capacity
Data are presented as decreasing value of lung volumes eg. Row 1, FEV1 per 500ml refers to 500ml lower FEV1
Model 1 adjusted for age, sex, ethnicity, height and weight.
Model 2 further adjusted for cigarette smoking status, log pack years, diabetes status, systolic blood pressure, heart rate, exercise, alcohol use, total and high density cholesterol.
