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, especially as compared to peripheral blood pressure, and its implications in assessing the efficacy of antihypertensive treatment with respect to cardiovascular risk factors, kidney disease, and mortality. There is an emerging movement for clinicians to begin using central aortic blood pressure, instead of peripheral blood pressure, as a guide for clinical decisions.
