BACKGROUND: Carotid-femoral pulse wave velocity (cfPWV) is considered the gold standard for estimating central arterial stiffness, an independent risk factor for cardiovascular disease (CVD) risk. Appropriately measuring cfPWV requires technical expertise, palpation of the carotid artery—which can cause participant discomfort—and may be confounded by factors such as carotid artery plaque, which reduces accuracy. Measuring heart-femoral PWV (hfPWV) is an alternative that may make assessing AS more accessible to clinicians, however, the extent of its agreement to cfPWV is not yet fully known. METHODS: Five young, healthy female adults aged 26.6 ± 5.9 years old (out of forty total planned) were recruited. hfPWV and cfPWV were measured using electrocardiogram (Equivital) and photoplethysmography, respectively. Measurements were recorded after a five-minute resting period between supine, semi-recumbent, and seated postures. Agreement between the two measurements was determined using the correlation class coefficient (CCC). RESULTS: Analysis is ongoing. However, analysis of a preliminary sample size n = 5 resulted in a CCC of 0.0395 between hfPWV and cfPWV. CONCLUSIONS: The current preliminary findings indicate that there is poor agreement between hfPWV and cfPWV. The results at this time, however, are underpowered. Once the study is completed, the conclusions may serve to provide clinicians additional tools to assess cardiovascular health. FUNDING: No funding applicable.
