Understanding the Diagnostic Value of Central Aortic Blood Pressure

Why Measure Central Aortic Blood Pressure?

Cardiovascular disease is the leading cause of death worldwide — and elevated blood pressure is the clearest modifiable risk factor. Extensive research shows that central aortic blood pressure measurement, which is the pressure measured at the heart, offers complementary data to brachial pressure measurement that can help health professionals optimize hypertension treatment.

      "You really can't practice good clinical medicine now without measuring central blood pressure. You can’t predict risk. You can’t predict goals. You can’t predict treatment. You don’t know how stiff the arteries are. You just have to have it.”

      Pressure Wave Form Analysis (PWA) Explained

      ATCOR’s SphygmoCor® XCEL PWA (pulse wave analysis) uses a standard brachial cuff to measure brachial systolic and diastolic pressures and capture a brachial waveform. The brachial waveform is then analyzed to provide a central aortic waveform. Noninvasive central blood pressure measurements such as central aortic systolic blood pressure, central pulse pressure, and an aortic augmentation index (AIx) are also reported.

      Two patients with equivalent brachial pressures (Figure 1) but with significantly different central arterial pressure waveforms (Figure 2). The difference in waveform shapes, due to differences in arterial stiffness and the effects of wave reflections, affect the aortic but not the brachial systolic and pulse pressures.
