Résumé
Chronic venous disease (CVD) is a common vascular disorder with manifestations ranging from asymptomatic spider veins to venous ulcers. Elevated right atrial pressure, otherwise called central venous pressure (CVP), can also result in edema and hyperpigmentation similar to chronic venous insufficiency. Obstructive sleep apnea (OSA) is a known risk factor for elevation of CVP. Prevalence rates of elevated CVP or OSA are unknown in patients presenting with a diagnosis of CVD. This is a single-center, retrospective, descriptive study of patients referred to our tertiary care center with a diagnosis of CVD. Each patient was evaluated by simultaneous venous duplex ultrasound (to assess venous reflux) and limited echocardiography of the right side of the heart (to assess elevated CVP). We assessed the prevalence and predictors of elevated CVP in this cohort using multivariate logistic regression. A total of 264 patients with CVD were evaluated, and of these, 22.7% had elevated CVP and 26.9% had OSA. There was no significant difference in the prevalence of OSA or elevated body mass index in the group with elevated CVP compared with patients with normal CVP. The predictors of elevated CVP were age >64.6 years (odds ratio [OR], 1.03; 95% confidence interval [CI], 1.003-1.05; P = .026), diabetes mellitus (OR, 2.19; 95% CI, 1.05-4.5; P = .035), and right lower extremity Venous Clinical Severity Score of ≥8.5 (OR, 1.098; 95% CI, 1.011-1.193; P = .026). Other predictors included prior history of pulmonary embolism and renal insufficiency. Compared with the general population, the prevalence of elevated CVP and OSA is significant in this cohort of patients. Age, diabetes, and right lower extremity chronic venous insufficiency symptoms seem to be predictors of elevated CVP. Larger, population-based prevalence studies are needed to confirm these findings.

BACKGROUND
Chronic venous disease (CVD) is a common vascular disorder with manifestations ranging from asymptomatic spider veins to venous ulcers. Elevated right atrial pressure, otherwise called central venous pressure (CVP), can also result in edema and hyperpigmentation similar to chronic venous insufficiency. Obstructive sleep apnea (OSA) is a known risk factor for elevation of CVP. Prevalence rates of elevated CVP or OSA are unknown in patients presenting with a diagnosis of CVD.
METHODS
This is a single-center, retrospective, descriptive study of patients referred to our tertiary care center with a diagnosis of CVD. Each patient was evaluated by simultaneous venous duplex ultrasound (to assess venous reflux) and limited echocardiography of the right side of the heart (to assess elevated CVP). We assessed the prevalence and predictors of elevated CVP in this cohort using multivariate logistic regression.
RESULTS
A total of 264 patients with CVD were evaluated, and of these, 22.7% had elevated CVP and 26.9% had OSA. There was no significant difference in the prevalence of OSA or elevated body mass index in the group with elevated CVP compared with patients with normal CVP. The predictors of elevated CVP were age >64.6 years (odds ratio [OR], 1.03; 95% confidence interval [CI], 1.003-1.05; P = .026), diabetes mellitus (OR, 2.19; 95% CI, 1.05-4.5; P = .035), and right lower extremity Venous Clinical Severity Score of ≥8.5 (OR, 1.098; 95% CI, 1.011-1.193; P = .026). Other predictors included prior history of pulmonary embolism and renal insufficiency.
CONCLUSIONS
Compared with the general population, the prevalence of elevated CVP and OSA is significant in this cohort of patients. Age, diabetes, and right lower extremity chronic venous insufficiency symptoms seem to be predictors of elevated CVP. Larger, population-based prevalence studies are needed to confirm these findings.
