摘要

Background

immediate post-exercise blood pressure (BP) is associated with an increased vascular stiffness. It is not clear whether it is capable of identifying atherosclerotic plaques and changes in vascular structure, which would be clinically useful in identifying older adults with a subclinical vascular impairment linked to future cardiovascular diseases.

Aims

The purpose of this study was to investigate the association of immediate post-exercise BP and carotid intima-media thickness.

Methods

This cross-sectional investigation involved 105 older adults (aged 67 ± 9 years; 77% female), without diagnosed cardiovascular disease. Carotid intima-media thickness (cIMT) was assessed using ultrasound; systolic BP was measured before and immediately after a 3-min moderate walking test, following stage 1 of Bruce protocol. Robust Poisson regression model was employed to analyze the prevalence ratio (PR) and 95% confidence intervals (CI) for increased cIMT.

Results

No significant association between immediate post-exercise systolic BP and cIMT was observed. Older adults in the highest quartile of immediate post-exercise systolic BP did not demonstrate increased PR of having elevated cIMT (PR 0.83, 95% CI 0.54, 1.27, p = 0.396).

Conclusions

Our findings indicate that immediate post-exercise systolic BP following a brief, moderate exercise is not associated with cIMT in older adults.
