Abstract

Background: Although acute coronary syndrome (ACS) and stroke are known to increase after earthquake, few data exist regarding the effect of earthquake on these cardiovascular events in rural areas. Methods and Results: The Noto Peninsula earthquake with a magnitude of 6.9 occurred at 9:45 a.m. on 25 March 2007. The first case of ACS occurred approximately 15 min later, whereas cerebral hemorrhage (CH) occurred 72 h after the onset of earthquake. During the 35 days after earthquake, among 49 patients who were attended by local ambulance, 5 patients with ACS (10.2%) and 8 with CH (16.3%) were documented and 4 died. The total number of both ACS and CH cases was greater than the averages for the same period of the past 3 years in this area (2.0 vs 5 and 2.3 vs 8, P<0.01). Interestingly, the most cases of ACS had occurred within 7 days after earthquake and for CH not until 35 days later. Conclusions: Even in rural areas a severe earthquake results in increased incidence of ACS and CH, which can occur at different times after the event, although the effects of other environmental factors should be further investigated.
