Standard formulas and individualised parenteral nutrition preparations in very low birth weight infants.

OBJECTIVES

Chronic inflammatory arthritis (CIAs), including rheumatoid arthritis (RA), psoriatic arthritis (PsA) and ankylosing spondylitis (AS) are characterised by high cardiovascular disease (CVD) risk, partly due to endothelial dysfunction and increased arterial stiffness of the carotid artery and aorta. The aim of the present study is to determine whether ultrasonography measures of carotid and aortic stiffness are correlated with left ventricular mass and function in patients affected by CIAs.

METHODS

In this cross-sectional study, we consecutively enrolled outpatients diagnosed with CIAs with no overt CVD. For each participant we assessed disease characteristics, CVD risk factors, medications, including disease-modifying anti-rheumatic drugs (DMARDs), blood pressure, lipids and glucose levels. Carotid ultrasonography was performed in all patients using carotid distensibility (CD) and aortic stiffness index (AoSI) as measures of arterial stiffness. Participants underwent the same day a full echocardiographic study including assessment of left ventricular function and mass (LVM).

RESULTS

The study population comprised 208 CIAs patients (mean age 57.4±11.4 y; females 63.9%), including 137 (65.9%) RA, 42 (20.2%) PsA and 29 (13.9%) AS patients. In multiple regression analysis, CD correlated with age (β=-0.198, p<0.0001), mean arterial pressure (β=-0.281, p<0.0001) and treatment with DMARDs (β=-1.976, p=0.021), while AoSI was not associated with any anthropometric, haemodynamic or clinical covariates. CD was inversely related to LVM (r=-0.20, p=0.005), whereas AoSI was directly correlated with diastolic function of the left ventricle (E/E'; r=0.191, p=0.007).

CONCLUSIONS

Our results underline the strict correlation between arterial stiffness and left ventricular mass and function in patients with CIAs.
