Implication
May aid preclinical risk detection via arterial elasticity; leaves open whether it improves stratification or guides therapy.
Key Points
- To review the pathophysiological role of endothelial dysfunction and decreased arterial compliance in cardiovascular risk, and to evaluate noninvasive methods for clinical risk stratification.
- Reviewed mechanisms of endothelial injury, focusing on reduced nitric oxide bioavailability, smooth muscle changes, and arterial stiffening.
- Evaluated diagnostic technologies for assessing arterial elasticity, with emphasis on office-based, noninvasive pulse contour analysis.
- Endothelial dysfunction reduces nitric oxide secretion, prompting arterial stiffening and creating a feedback loop that elevates blood pressure and accelerates atherosclerosis in hypertensive, diabetic, and normotensive individuals.
- Noninvasive pulse contour analysis enables practical measurement of small-artery elasticity to identify patients at elevated cardiovascular risk before clinical disease manifests.

Population
Patients at risk for cardiovascular events, including those with hypertension, diabetes, smokers, and normotensive patients before clinical disease appearance

Exposure
Pulse contour analysis for noninvasive measurement of arterial elasticity

Outcome
Cardiovascular risk stratification and identification of patients at risk for CV eventssurrogate
Pulse contour analysis is a promising noninvasive tool for measuring arterial compliance to identify early cardiovascular risk, though its impact on therapeutic decision-making requires further validation.
Limitations
- Further research is needed to confirm whether this method offers a means of improving risk stratification and therapeutic decision making
