As age increases the aortic diameter tends to increase and the peak velocity of systolic flow tends to decrease until patients reach an age greater than 60 years old. [6] Patients over the age of 60 tend to have an increase of peak systolic velocity. [6]
Aortic unfolding is an abnormality visible on a chest X-ray, that shows widening of the mediastinum which may mimic the appearance of a thoracic aortic aneurysm. [ 1 ] With aging, the ascending portion of the thoracic aorta increases in length by approximately 12% per decade, whereas the diameter increases by just 3% per decade.
A thoracic aorta diameter greater than 3.5 cm is generally considered dilated, whereas a diameter greater than 4.5 cm is generally considered to be a thoracic aortic aneurysm. [4] Still, the average diameter in the population varies by for example age and sex.
The aortic arch, arch of the aorta, or transverse aortic arch (English: / eɪ ˈ ɔːr t ɪ k / [1] [2]) is the part of the aorta between the ascending and descending aorta. The arch travels backward, so that it ultimately runs to the left of the trachea .
Aortic stenosis is the most common valvular heart disease in the developed world. [4] It affects about 2% of people who are over 65 years of age. [1] Estimated rates were not known in most of the developing world as of 2014. [5] In those who have symptoms, without repair the chance of death at five years is about 50% and at 10 years is about 90 ...
An aortic aneurysm is an enlargement (dilatation) of the aorta to greater than 1.5 times normal size. [1] Typically, there are no symptoms except when the aneurysm dissects or ruptures, which causes sudden, severe pain in the abdomen and lower back. [2] [3] The etiology remains an area of active research.
When examining the cost-effectiveness of statin use in older adults, the researchers report that statins were cost-effective, with the cost per quality-adjusted life years gained below £3,502 ...
Increased aortic PWV has been shown to predict cardiovascular, and in some cases all-cause, mortality in individuals with end stage kidney disease, [15] hypertension, [16] diabetes mellitus [17] and in the general population. [18] [19] However, at present, the role of measurement of PWV as a general clinical tool remains to be established ...
