Arterial stiffness measurements, generally from pulse wave velocity (PWV), are widely used with little knowledge of their relationship to long-term cardiovascular mortality in general populations. Methods and Results We studied a cohort of 492 Japanese-Americans living in Hawaii (mean age: 63.7 +/- 8.8 years) to assess the relationship between PWV and cardiovascular disease mortality and all-cause mortality. During the 10-year follow-up, 43 patients died (14 from cardiovascular events). The cohort was divided into 2 groups by the cut-off value of PWV (9.9 m/s) represented in the receiver operating characteristic curve. The risk ratio for PWV values >9.9 m/s to all-cause mortality was 1.28 [95% confidence interval (CI): 1.14 - 1.42], and adjusted for other risk factors this ratio was 1.42 (95% CI: 0.96 - 2.11). The corresponding risk ratios for cardiovascular mortality was 4.46 (95% CI: 1.61 - 12.32) and 4.24 (95% CI: 1.39 - 12.96), respectively. Conclusions The present study demonstrated that an increased PWV value is associated with future cardiovascular disease death in Japanese-Americans living in Hawaii.
