Aortic stiffness and pulse wave reflection in young subjects with migraine: A case-control study.
Summary of "Aortic stiffness and pulse wave reflection in young subjects with migraine: A case-control study."
Migraine has been associated with an increased risk for ischemic stroke and other cardiovascular (CV) events, including angina, myocardial infarction, and CV death, but the mechanisms that link migraine to CV disease remain uncertain. We hypothesized that aortic pulse wave velocity (PWV), a direct measure of aortic stiffness and an independent predictor of stroke and CV disease, may be increased in young migraineurs with no overt CV disease or major CV risk factors.
We studied 60 subjects with migraine (age 33 ± 8 years, 85% women, blood pressure 119/74 ± 11/9 mm Hg) and 60 age-, sex-, and blood pressure-matched healthy control subjects. In all participants, carotid-femoral PWV and aortic augmentation index were determined by applanation tonometry. Cases and controls were free from overt CV disease, diabetes, and major CV risk factors.
Subjects with migraine had a higher aortic PWV (7.6 ± 1.2 vs 6.4 ± 1.1 m×s(-1), p < 0.001) and aortic augmentation (heart rate-adjusted augmentation index, 0.17 ± 0.13 vs 0.08 ± 0.15, p < 0.001) than matched control subjects. Migraine patients with aura (n = 17) had higher aortic PWV than those without aura (n = 43; 8.2 ± 1.2 vs 7.4 ± 1.1 m×s(-1), p = 0.027). Age, mean arterial pressure as a measure of distending pressure, and migraine (all p < 0.05) independently predicted aortic PWV when a consistent number of CV risk factors was simultaneously controlled for.
Migraine is independently associated with increased aortic stiffness and enhanced pressure wave reflection. This finding, obtained in young subjects without major CV risk factors, may represent one possible mechanism underlying the increased CV risk in migraine patients.

Medical and Biotech [MESH] Definitions
Small clusters of chemoreceptive and supporting cells located near the ARCH OF THE AORTA; the PULMONARY ARTERIES; and the coronary arteries. The aortic bodies sense PH; CARBON DIOXIDE; and oxygen concentrations in the BLOOD and participate in the control of RESPIRATION. The aortic bodies should not be confused with the PARA-AORTIC BODIES in the abdomen (which are sometimes also called aortic bodies).
Use of a pulse of X-rays or fast electrons to generate free radicals for spectroscopic examination.
An electrochemical technique for measuring the current that flows in solution as a function of an applied voltage. The observed polarographic wave, resulting from the electrochemical response, depends on the way voltage is applied (linear sweep or differential pulse) and the type of electrode used. Usually a mercury drop electrode is used.
Small masses of chromaffin cells found near the SYMPATHETIC GANGLIA along the ABDOMINAL AORTA, beginning cranial to the superior mesenteric artery (MESENTERIC ARTERY, SUPERIOR) or renal arteries and extending to the level of the aortic bifurcation or just beyond. They are also called the organs of Zuckerkandl and sometimes called aortic bodies (not to be confused with AORTIC BODIES in the THORAX). The para-aortic bodies are the dominant source of CATECHOLAMINES in the FETUS and normally regress after BIRTH.
Pathological condition characterized by the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to regurgitation. It is caused by diseases of the AORTIC VALVE or its surrounding tissue (aortic root).
