Clinical correlates of longitudinal tracking of left ventricular diameter in diastole.
| Covariates | Coefficient | 95% CI |
|---|---|---|
| Age (10 year increase) | — | — |
| with diabetes | −0.11 | (−0.45, 023) |
| without diabetes | −0.60 | (−0.70, −0.50) |
| Male Sex * | 4.38 | (4.17, 4.58) |
| BMI (5 kg/m2 increase) | — | — |
| men | 0.83 | (0.66, 1.00) |
| women | 1.05 | (0.94, 1.17) |
| SBP (10 mm Hg increase) | 0.24 | (0.17, 0.30) |
| DBP (10 mm Hg increase) | −0.27 | (−0.38, −0.17) |
| Diabetes † | −0.31 | (−0.72, 0.10) |
CI, confidence interval; BMI, body mass index; SBP, systolic blood pressure; DBP, diastolic blood pressure. The coefficients represent the increase in left ventricular diameter in diastole in mm per increase in the continuous covariates (or presence versus absence of categorical covariates). All models also adjusted for examination cycle and significant interaction terms; any non-significant covariates were retained in the model if they contributed to a significant interaction term. In a model that included pulse pressure instead of SBP and DBP, the coefficient of mm change in LVDD per 10 mm Hg increase in pulse pressure was 0.31 (95% CI 0.21, 0.40) for men and 0.19 (95% CI 0.12, 0.27) for women.
Given presence of a significant BMI interaction term, coefficients are for individuals with a BMI of 25 kg/m2.
Given presence of a significant age interaction term, coefficients are for individuals at age 50 years.
