Arterial stiffness and multiple organ damage: a longitudinal study in population

Area of Science:

• Cardiovascular Science
• Gerontology
• Nephrology

Background:

• Arterial aging, indicated by pulse-wave velocity (PWV), is linked to simultaneous multiple organ damage.
• Previous studies were cross-sectional, limiting understanding of arterial aging trajectories.

Purpose of the Study:

• To investigate the relationship between repeated measures of PWV and traditional cardiovascular risk factors.
• To analyze these factors in individuals who developed simultaneous multiple organ damage (heart, carotid artery, kidney) in the SardiNIA study.

Main Methods:

• A cohort study analyzing retrospective data from 2130 participants in the SardiNIA study over 9 years.
• Organ damage assessed via left ventricular hypertrophy (heart), intima-media thickness/plaque (carotid artery), and reduced estimated glomerular filtration rate (kidney).
• Statistical analysis controlled for traditional cardiovascular risk factors to evaluate PWV's predictive value.

Main Results:

• Each 1 m/s increase in baseline PWV was associated with a 93% higher odds of developing simultaneous three-organ damage (SHATS).
• Each 0.01 m/s annual increase in PWV correlated with a 31% greater odds of developing SHATS.
• These associations remained significant after controlling for traditional cardiovascular risk factors.

Conclusions:

• Arterial stiffness, clinically measured by PWV, serves as an integrated predictive marker.
• PWV effectively predicts multiple age-associated organ damage conditions.
• PWV is a valuable clinical tool for assessing the risk of widespread organ damage due to arterial aging.
