OBJECTIVE: To characterise and compare the potentiation of arterial stiffness and vascular ageing by opioids in men and women.
DESIGN: Cross-sectional and longitudinal studies of 576 clinical controls and 687 opioid-dependent patients (ODP) on 710 and 1305 occasions, respectively, over a total of 2382 days (6.52 years), 2006-2011. Methodology Radial pulse wave analysis with Atcor SphygmoCor system (Sydney).
SETTING: Primary care.
CONTROLS: General practice patients with non-cardiovascular disorders, and university student controls. ODP: Patients undergoing clinical management of their opioid dependence. CONTROLS had lower chronological ages (CAs) than ODP (30.0±0.5 vs 34.5±0.3, mean±SEM, p
PRIMARY OUTCOME MEASURES: Vascular Reference Age (RA) and the ratio of vascular age to chronological age (RA/CA).
SECONDARY OUTCOME MEASURES: Arterial stiffness including Augmentation Index.
RESULTS: After BMI adjustment, RA in ODP was higher as a function of CA and of time (both p
CONCLUSIONS: Data show that lifetime opioid exposure, an interactive cardiovascular risk factor, particularly in women, is related to linear, quadratic, cubic and quartic functions of treatment duration and is consistent with other literature of accelerated ageing in patients with OD.
