arterial age
A calculated parameter that estimates vascular aging relative to chronological age based on arterial stiffness measurements.
Full Definition
Arterial age represents a calculated estimate of vascular aging that compares an individual's arterial stiffness measurements to normative values for healthy individuals across different age groups. It is typically derived from pulse wave velocity measurements and expressed as years above or below chronological age. For example, a 50-year-old with arterial stiffness comparable to a healthy 65-year-old would have an arterial age of 65 years. This concept helps communicate cardiovascular risk in an easily understood format and may motivate lifestyle modifications. Arterial age calculation incorporates multiple factors including pulse wave velocity, blood pressure, and sometimes additional vascular parameters. The measurement provides insight into accelerated vascular aging associated with cardiovascular risk factors.
Usage
Usage note: Express in years; clearly distinguish from chronological age in patient communication.
In Context
- "The patient's arterial age of 68 years exceeded his chronological age of 55 years, indicating accelerated vascular aging." — Vascular risk assessment
- "Improvement in arterial age from 72 to 64 years demonstrated the benefits of intensive lifestyle intervention." — Follow-up evaluation report
