VascVita's health calculations and wellness metrics are grounded in peer-reviewed scientific research. The following sources inform our algorithms, activity thresholds, and vascular estimation models.

Arterial Stiffness Estimation

Citation

Greve SV, et al. (2016). Estimated carotid-femoral pulse wave velocity has similar predictive value as measured carotid-femoral pulse wave velocity. Journal of Hypertension, 34(7), 1279–1289.

Used In

This study validates the Greve 2 mathematical model used in VascVita to estimate pulse wave velocity (PWV), a key indicator of arterial stiffness.

DOI

Pulse Wave Estimation

Citation

Heffernan KS, et al. (2023), Estimated pulse wave velocity as a measure of vascular aging. PLoS ONE 18(1): e0280896.

Used In

This study validates the estimated pulse wave velocity (ePWV) as a simplified, high-accuracy proxy for vascular aging, enabling arterial stiffness screening using only age and blood pressure without specialized equipment.

DOI

PWV Population Reference Values

Citation

Reference Values for Arterial Stiffness' Collaboration. (2010). Determinants of pulse wave velocity in healthy people and in the presence of cardiovascular risk factors: 'establishing normal and reference values'. European Heart Journal, 31(19), 2338–2350.

Used In

Established the definitive age- and sex-specific reference values (nomograms) for pulse wave velocity, providing the clinical gold standard to distinguish normal vascular aging from stiffness driven by cardiovascular risk factors.

DOI

Exercise & Arterial Health

Citation

Ashor AW, et al. (2014). Exercise modalities and endothelial function: a systematic review and dose–response meta-analysis of randomized controlled trials. PLOS ONE, 9(10), e110034.

Used In

Research demonstrating exercise-induced reductions in arterial stiffness, establishing the 1,000 MET-min/week threshold used in activity recommendations.

DOI

Sleep & Arterial Stiffness

Citation

Wang H, et al. (2021). Sleep duration and arterial stiffness: a U-shaped association study linking short and long sleep durations with increased pulse wave velocity.

Used In

Established a U-shaped association between sleep duration and arterial stiffness, demonstrating that both short and long sleep durations are strongly associated with increased pulse wave velocity.
