Abstract

Background—: Systolic blood pressure and pulse pressure are substantially higher in older adults. The relative contributions of increased forward versus reflected pressure wave amplitude or earlier arrival of the reflected wave to elevated pulse pressure remain controversial. Methods and Results—: We measured proximal aortic pressure and flow, forward pressure wave amplitude, global wave reflection, reflected wave timing, and pulse wave velocity noninvasively in 6417 (age range, 19 to 90 years; 53 women) Framingham Heart Study Third Generation and Offspring participants. Variation in forward wave amplitude paralleled pulse pressure throughout adulthood. In contrast, wave reflection and pulse pressure were divergent across adulthood: In younger participants, pulse pressure was lower and wave reflection was higher with advancing age, whereas in older participants, pulse pressure was higher and wave reflection was lower with age. Reflected wave timing differed modestly across age groups despite considerable differences in pulse wave velocity. Forward wave amplitude explained 80 (central) and 66 (peripheral) of the variance in pulse pressure in younger participants (<50 years) and 90 and 84 in the older participants (≥50 years; all P <0.0001). In a stepwise model that evaluated age–pulse pressure relations in the full sample, the late accelerated increases in central and peripheral pulse pressure were markedly attenuated when variation in forward wave amplitude was considered. Conclusions—: Higher pulse pressure at any age and higher pulse pressure with advancing age is associated predominantly with a larger forward pressure wave. The influence of wave reflection on age-related differences in pulse pressure was minor.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
