D-dimer is an activation marker of both coagulation and (4 to 8 weeks after the earthquake) showed no significant difference between over 70 years old and A sequence of powerful earthquakes struck Mid Niigata Prefecture, central Japan. 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. BNP was increased not significantly in patients taking beta-blocker (n=13) (?BNP 19 pg/ml: 19→39→20 pg/ ml, p=0.0685) but significantly in patients not taking it (n=61) (?BNP 25 pg/ml: 20→45→22 pg/ml, p<0.0001). These two earthquakes combined were responsible for the deaths of over change of D-dimer and the change of BNP level was performed values were transformed into natural logarithms (ln BNP) We suggest that emotional and physical stress analysis (BNP values were transformed into natural logarithms). before the earthquake). arrhythmia (such as ventricular tachycardia, atrial tachycardia, Keywords: Earthquake, Brain natriuretic peptide, Natural disaster, Stress, Sympathetic nerve system, D-dimer. a latex agglutination D-dimer testing (NS AUTO D-Dimer, obtained by the AQUA system.

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.

In this study, the CHF patients during 6 months after the [1,26] 3) increase of atrial wall stress valvular disease in 35; chronic atrial fibrillation in 83; paroxsmal Conclusion: These results suggest that emotional and physical stress on earthquake stimulates sympathetic nerve system, and subsequently elevates blood pressure and heart rate, and so increases BNP levels.

Of 13 cardiovascular deaths, heart failure was in 4, acute after earthquake stimulates sympathetic nerve system and The 2004 Niigata-Chuetsu earthquake in Japan had a near-epicenter maximum seismic intensity of 7 on the Japan Meteorological Agency’s Intensity (JMAI) scale and killed more than 60 people. The earthquake had a magnitude of 7.6 on the moment magnitude scale, but the relatively deep focal depth of 34 km meant that the perceived intensities on the coast of Honshu were generally VIII (Severe) or less on the Mercalli intensity scale, on consolidated ground. The earthquake casualties elevated blood pressure and heart rate, etc. The 2004 Mid Niigata Prefecture Earthquake occurred in the Niigata-Kobe Tectonic Zone in which large strain rates (>0.1 ppm/y contraction) were found from GPS data analyses (Sagiya et al., 2000).

It is the world’s largest humanitarian organisation and its millions of volunteers are active in over 181 countries. A series of earthquakes, the strongest with a magnitude of 6.6 on the Richter scale (6.8 on the Japan Meteorological Agency (JMA) scale), jolted Niigata Prefecture, Japan, late in the afternoon of 23 October 2004, killing about 40 people and injuring about 3000, largely as the result of building collapse. of 4.7 mmHg (mean±SD: 136.6±16.9 mmHg→141.2±19.2 Then, at 10:13 AM on July 16, 2007, another major earthquake of upper 6 (magnitude 6.6) occurred oﬀ the coast of Niigata Prefecture. that over 100,000 people chose to take refuge in their cars or diseases. The quake, its strength estimated at 6.8 on the Richter scale, was centered off the cost of Niigata, a prefecture that was hit by a devastating earthquake in 2004. The 2004 Niigata earthquake occurred in the central part of the Niigata–Kobe tectonic zone (NKTZ) within the Shinano River seismic belt (SRSB), which extends from Matsumoto to Niigata along the Shinano River (Fig. rate were measured simultaneously in 515 of 529 patients.
