Implication
This editorial highlights that non-invasive evaluation of pulsatile indices, specifically the augmentation index, is a valuable and superior tool compared to pulse pressure for predicting long-term cardiovascular risk in patients undergoing PCI.
Key Points
- To review the pathophysiological principles of arterial wave reflections and evaluate how pulsatile haemodynamics can improve cardiovascular risk assessment and therapeutic monitoring.
- Reviewed physical principles of pulsatile arterial haemodynamics and mathematical wave decomposition using Fourier analysis to model oscillatory blood pressure.
- Evaluated clinical literature and trial evidence comparing central aortic pressure with peripheral brachial pressure measurements.
- Synthesized findings regarding wave reflection parameters, including pulse wave velocity and augmentation index, in patients undergoing percutaneous coronary intervention and anti-hypertensive therapy.
- Peripheral systolic blood pressure and pulse pressure exceed central aortic values by approximately 12–14 mmHg due to wave reflection amplification at arteriolar branching points.
- In pharmacotherapy comparisons, a 4 mmHg difference in brachial systolic blood pressure between perindopril and atenolol translated to a 10 mmHg divergence in carotid systolic blood pressure.
- Arterial wave reflections measured via augmentation index independently predicted long-term severe cardiovascular events in coronary intervention patients, outperforming traditional pulse pressure.
