central aortic pressure
Blood pressure measured at the aortic root, considered more predictive of cardiovascular outcomes than peripheral blood pressure.
Full Definition
Central aortic pressure refers to the blood pressure measured at the aortic root, closer to the heart, rather than at peripheral sites like the brachial artery. This measurement is increasingly recognized as more predictive of cardiovascular outcomes and target organ damage than traditional peripheral blood pressure readings. Central aortic pressure can be estimated non-invasively using specialized devices that analyze pulse wave characteristics. The difference between peripheral and central pressure becomes more pronounced with aging and arterial stiffening.
Usage
Usage note: Distinguish from peripheral blood pressure measurements in cardiovascular risk assessment contexts.
In Context
- "The patient's central aortic pressure was significantly lower than the brachial measurement, indicating arterial stiffening." — cardiology consultation note
- "Central aortic pressure assessment may guide antihypertensive therapy more effectively than peripheral readings." — clinical research protocol
