Methods: This study included 529 outpatients (mean age: 69.8 years), whose BNP was measured within 4 weeks after the earthquake and additional 4 weeks after the former by immunoradiometric assay (Sionogi), and compared to BNP before the earthquake.

The October 23, 2004 Mid Niigata Prefecture earthquake of magnitude 6.8 in JMA scale and the subsequent aftershocks, which struck the inland area of Niigata prefecture, was the most severe earthquake to affect Japan since the 1995 Hyogo-ken Nambu earthquake. depth: Japan Meteorogical Agency) struck the Chuetsu with cardiac diseases, but also in those without cardiac diseases The relationship between the change of blood pressure death after the earthquake.
