The target blood pressure should be a mean arterial pressure (MAP) of 60 to 75 mmHg, or the lowest blood pressure tolerated. Initial decreases should be by about 20%. [2] The target heart rate is less than 65 beats per minute. Long-term blood pressure control is required for every person who has experienced aortic dissection. [42] [43]
Blood vessel coarctation, which is the narrowing of a blood vessel, also can cause dissection. Aortic dissections most often happen in the first 10 cm of the the aorta closest to the heart. In order for an aortic dissection to occur, an underlying condition usually has to exist that weakens the aorta’s wall.
Elevated central aortic blood pressure has generally been found to be a greater predictor of cardiovascular disease-related mortality, structural changes in the heart, and chronic kidney disease than elevated peripheral blood pressure (such as measured in the brachial artery, the main artery in the upper arm where blood pressure is most commonly measured).
Arterial dissections become life-threatening when growth of the false lumen prevents perfusion of the true lumen and the related end organs. For example, in an aortic dissection, if the left subclavian artery orifice were distal to the origin of the dissection, then the left subclavian would be said to be perfused by the false lumen, while the left common carotid (and its end organ, the left ...
Less common presentations include intracranial bleeding, aortic dissection, and pre-eclampsia or eclampsia. [6] Massive, rapid elevations in blood pressure can trigger any of these symptoms, and warrant further work-up by physicians. Physical exam would include measurement of blood pressure in both arms.
Pulse pressure is calculated as the difference between the systolic blood pressure and the diastolic blood pressure. [3] [4]The systemic pulse pressure is approximately proportional to stroke volume, or the amount of blood ejected from the left ventricle during systole (pump action) and inversely proportional to the compliance (similar to elasticity) of the aorta.
A study of people who died after traumatic aortic rupture found that in 55–65% of cases the damage was at the aortic isthmus and in 10–14% it was in the ascending aorta or aortic arch. [4] An angiogram will often show an irregular outpouching beyond the takeoff of the left subclavian artery at the aortic isthmus, representing an aortic ...
A normal systolic blood pressure will be less than 120 mm Hg, and a normal diastolic blood pressure will be less than 80 mm Hg. [3] A blood pressure that is more than 15 mm Hg different between the right and left arm may indicate a problem with the patient's blood vessels. [1] A normal heart rate is between 60 and 100 beats per minute.
