Association of blood pressure in the supine position with target organ damage in subjects over 60 years old

ObjectiveToexplore the correlation between blood pressure in the supine position and target organ damage in subjects over 60 years of age.MethodsIn 2444 individuals, we investigated the association of systolic blood pressure (SBP) in the supine position with the target organ damage indices microalbuminuria (ALBU), brachial–ankle pulse wave velocity (baPWV), and carotid intima–media thickness (IMT). Supine hypertension (SH) is defined as systolic blood pressure ≥ 140 mmHg and/or diastolic blood pressure ≥ 90 mmHg. Subjects were assigned to either the SH group (1275 cases) or the non-SH group (1169 cases).ResultsThe levels of ALBU, baPWV, and IMT, as well as the percentage of participants with ALBU > 30 mg/L, baPWV ≥ 1400 cm/s, and IMT ≥ 1 mm, were significantly higher in the SH group than in the non-SH group. Multivariate logistic regression analysis showed that SH was an independent risk factor for baPWV and IMT, but the relationship with ALBU was not statistically significant after correction for confoun...
