MiscellaneousComparison of the Incidence of Acute Decompensated Heart Failure Before and After the Major Tsunami in Northeast Japan
Section snippets
Methods
To elucidate the effects of tsunami on health problems, we defined 2 areas (Figure 1): the coastal area in the southern San-riku region damaged by the huge tsunami (tsunami area) and the northern San-riku region and inland of Iwate where minimal tsunami damage occurred (control area). The definition was based on the percent tsunami flood area per built-up area (%TFA) in each coastal municipality.1 This ratio represented the degree and extent of damage caused by the tsunami in the residential
Results
In the tsunami area during the 8 weeks after the disaster, 97 patients with ADHF were admitted. Compared to the number of the previous 2 years (n = 104), the relative risk of ADHF incidence in the tsunami area was 1.97 (95% CI 1.50 to 2.59). In contrast, in the control area, the number of hospitalized ADHF cases for the corresponding periods were 96 (sum of 2009 and 2010) and 61 (2011). There was no significant increase in ADHF numbers in the control area (relative risk 1.29, 95% CI 0.94 to
Discussion
The present hospital-based study has demonstrated that the number of cases of ADHF in the area devastated by the huge tsunami increased significantly for several weeks after the disaster, and this growth was significantly correlated with the degree of tsunami-induced destruction in residential areas or with the number of evacuees. In contrast, the number of hospitalized patients with ADHF did not change significantly in towns with a similar magnitude of earthquake but with no critical tsunami

Relationship between the flood disaster caused by the Reiwa first year east Japan typhoon and cardiovascular and cerebrovascular events in Nagano City: The SAVE trial
2021, Journal of CardiologyCitation Excerpt :Therefore, data predicting the incidences of cardiovascular and cerebrovascular diseases related to flood disasters are crucial to prevent additional burden on the health care system. Previous reports have indicated an increase in HF due to tsunami damage caused by an earthquake [8,18]. In previous reports, the peak occurrence was observed 3 to 4 weeks after the disaster; however, in the case of the Reiwa flood, a specific increase was observed immediately after the disaster.

2020, Environment InternationalThe Impact and Effectivity of an Inventory Survey for a Stroke Registry in Iwate Prefecture
2017, Journal of Stroke and Cerebrovascular DiseasesCitation Excerpt :To maintain a disease registry with a high degree of accuracy over the long term, a nonvoluntary inventory survey system was conducted for a large cohort study in the northern part of Iwate Prefecture to determine the prevalence of cerebrovascular and cardiovascular diseases and their risk factors from 2002 onward.1,2 After the Great East Japan Earthquake of 2011, this survey system was expanded to the whole coastal area of Iwate Prefecture to maintain disease registries with a high degree of accuracy even after a catastrophic disaster, and to determine the influence of the disaster on the occurrence of cerebrovascular and cardiovascular diseases in the coastal area.3,4 For the survey of cerebrovascular diseases, trained research nurses were assigned to core hospitals with neurologists or neurosurgeons, whereas research doctors and trained research nurses were dispatched to the noncore hospitals without neurologists or neurosurgeons.
Long-term prognostic impact of the Great East Japan Earthquake in patients with cardiovascular disease – Report from the CHART-2 Study
2017, Journal of CardiologyCitation Excerpt :We also reported that the weekly occurrences of several CVDs, including heart failure (HF), pulmonary thromboembolism, and infectious endocarditis, were sharply and transiently increased after the GEJE in patients admitted to the cardiology departments at 10 hospitals in the disaster area after the earthquake [4]. Others also reported an increase of out-of-hospital cardiac arrest in the first 4 weeks after the GEJE [6] and an increase in acute decompensated heart failure (ADHF) [7,8]. These lines of evidence suggest that the GEJE caused a rapid and transient increase in all types of CVD in the disaster area.
Long-Term Effects of the 2011 Japan Earthquake and Tsunami on Incidence of Fatal and Nonfatal Myocardial Infarction
2017, American Journal of CardiologyCitation Excerpt :To examine the impact of the disaster on acute cardiac events, the study area was divided into 2 zones—the low-impact zone and the high-impact zone—according to the degree of tsunami damage in each municipality (Figure 1, right). As described in our previous study,8 this definition was based on the percentage of tsunami flooding per built up area (%TFA) in each municipality. This ratio has been suggested to represent the degree and extent of damage caused by the tsunami in the residential areas of each town.
