Key result
Brachial-ankle pulse wave velocity in the top decile was associated with a higher risk of all-cause mortality compared to the whole study population (HR 1.56; 95% CI 1.16-2.08; P≤0.003).
Why the study?
Does high brachial-ankle pulse wave velocity predict mortality in an elderly Chinese population?
Population
3,876 elderly adults living in a suburban town of Shanghai, mean age 68.1±7.3 years, 44.2% male, including…

High baPWV may flag mortality risk in elderly Chinese hypertensives but should not yet change practice; leaves open prospective validation of incremental utility.

Does high brachial-ankle pulse wave velocity predict mortality in an elderly Chinese population?
Hazard Ratio: 1.56 (95% CI 1.16–2.08)
p-value: p=≤0.003
Markedly increased brachial-ankle pulse wave velocity is a significant predictor of all-cause mortality in elderly Chinese individuals, particularly those with hypertension.
Sheng et al. (2014) conducted a cohort in Elderly population (n=3,876). Brachial-ankle pulse wave velocity (top decile: 23.3-39.3 m/s) vs. Whole study population was evaluated on All-cause mortality (HR 1.56, 95% CI 1.16-2.08, p=≤0.003). Brachial-ankle pulse wave velocity in the top decile was associated with a higher risk of all-cause mortality compared to the whole study population (HR 1.56; 95% CI 1.16-2.08; P≤0.003).
