Is reproducibility of ultrasonographically determined intima-media thickness dependent on arterial wall thickness . The Tromsø Study?
We conclude that B-mode ultrasound provides reproducible estimates of the IMT in both the near and far walls of the carotid artery. Although measurement error is generally small, it increases proportionally with the level of IMT.
25OHD deficiency was associated with orthostatic hypotension in oldest-old women, due to a greater drop in diastolic blood pressure on standing. This finding may lead to better understanding of the pathophysiology of falls in oldest-old adults with vitamin D deficiency.
