| Outline of Final Research Achievements |
Although cardiovascular events have been reported to increase after great disaster, the mechanisms remain unknown. Decreased heart rate (HR) variability predicts cardiovascular mortality in various populations. We have constructed Holter ECG big data in a project named the Allostatic State Mapping by Ambulatory ECG Repository (ALLSTAR) since 2007. We examined the impact of the Great East Japan Earthquake that occurred in 2011 on HR variability using the database of ALLSTAR project. In affected area, deceleration capacity, a powerful predictor for mortality among measures of HR variability, was decreased in 2011 compared with other years. In unaffected area, no such decrease was observed. We observed that the Great East Japan Earthquake decreased HR variability. These results suggest that decreased HR variability may contribute to an increased risk for cardiovascular mortality after great disaster.
