Abstract

OBJECTIVES: To evaluate vascular wall structure and conduit artery stiffness in patients with primary aldosteronism. METHODS: This observational study, conducted in a University Hypertension Center, evaluated the carotid wall by 2-D ultrasonography and ultrasonic tissue characterization, and analyzed arterial stiffness by applanation tonometer. Twenty-three consecutive patients with primary aldosteronism, 24 matched patients with essential hypertension and 15 controls were studied. Intima-media thickness and corrected integrated backscatter signal of the carotid arteries were evaluated. Radial and femoral pulse wave velocity and aortic augmentation index were also investigated. RESULTS: Intima-media thickness in patients with essential hypertension (0.69 +/- 0.03 mm) was higher (P < 0.04) than that in controls (0.59 +/- 0.02 mm). This finding was more evident in primary aldosteronism patients (0.84 +/- 0.03 mm), in whom intima-media thickness was greater than that in controls (P < 0.0001) or in patients with essential hypertension (P < 0.01). Similarly, corrected integrated backscatter signal in patients with essential hypertension (-23.6 +/- 0.35 dB) was higher (P < 0.0001) than that in controls (-26.2 +/- 0.44 dB), but it was even more elevated in patients with primary aldosteronism (-22.1 +/- 0.46 dB), who showed greater corrected integrated backscatter signal than was the case in patients with essential hypertension (P < 0.009) or in controls (P < 0.0001). Femoral pulse wave velocity was higher in primary aldosteronism patients (10.8 +/- 0.57 m/s) than in patients with essential hypertension (9.1 +/- 0.34 m/s, P < 0.03) or in controls (7.1 +/- 0.51 m/s, P < 0.0001). Femoral pulse wave velocity was lower in controls than in patients with essential hypertension (P < 0.0001). The same pattern was observed for radial pulse wave velocity. Aortic augmentation index was higher in primary aldosteronism patients (28.2 +/- 2.1%) than in patients with essential hypertension (26.0 +/- 1.8%) or in controls (16.8 +/- 2.0%, P < 0.001). Patients with essential hypertension likewise exhibited higher aortic augmentation index than controls (P < 0.001). CONCLUSION: Aldosterone excess is responsible per se for vascular morphological (wall thickening and carotid artery fibrosis) and functional (central stiffness) damage.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
