Aortic Pressure
Central aortic blood pressure (CAP or CASP) is the blood pressure at the root of aorta. Studies have shown the importance of central aortic pressure and its implications in assessing the efficacy of antihypertensive treatment with respect to cardiovascular risk factors. The traditional method of measuring blood pressure in the arms has been shown to underestimate the efficacy of medications such as amlodipine and overestimate the efficacy of those like atenolol. A clinical trial demonstrated that different medications for lowering blood pressure have different effects on the central aortic pressure and blood flow characteristics, despite producing similar branchial blood pressure readings. The study also indicated that the CAP is a better independent predictor of cardiovascular and kidney outcomes. * References Further readingCAFE - The Conduit Artery Functional Endpoint Study* * * * {{DEFAULTSORT:Blood Pressure ...

Aorta The aorta ( ) is the main and largest artery in the human body, originating from the left ventricle of the heart and extending down to the abdomen, where it splits into two smaller arteries (the common iliac arteries). The aorta distributes oxygenated blood to all parts of the body through the systemic circulation. Structure Sections In anatomical sources, the aorta is usually divided into sections. One way of classifying a part of the aorta is by anatomical compartment, where the thoracic aorta (or thoracic portion of the aorta) runs from the heart to the diaphragm. The aorta then continues downward as the abdominal aorta (or abdominal portion of the aorta) from the diaphragm to the aortic bifurcation. Another system divides the aorta with respect to its course and the direction of blood flow |
