In conclusion, simple reaction time at baseline was an independent
predictor for all-cause and cardiovascular mortality in adults aged 20
to 59 years. Furthermore, adding simple reaction time to the Framinghamrisk
factors significantly improved the value of cardiovascularmortality
predictions. Although this study has limitations due to a single
measurement of simple reaction time at baseline and a long interval between
measurement and follow-up, and the mechanisms relating delayed
simple reaction time to increased cardiovascular mortality risk
remains unclear, we suggest the importance of simple reaction time to
cardiovascular mortality and demonstrated that simple reaction time
may have the ability to determine the subjects likely to suffer future cardiovascular
mortality.
