Abstract
BACKGROUND Possible etiologies of out-of-hospital cardiac arrest (OHCA), including aortic dissection, ruptured aortic aneurysms, and pulmonary embolism, may be classified as non-cardiac causes. We investigated whether cardiac and non-cardiac OHCAs increased following the Kumamoto earthquake and whether the impact on OHCAs extended to regions far from the epicenter. METHODS AND RESULTS We prospectively analyzed a nationwide registry of patients who experienced OHCAs between January 2013 and December 2019. Data from cases registered in 7 prefectures, including Kumamoto (Kyushu region; n=82,060), in the All-Japan Utstein Registry were analyzed for OHCAs of cardiac and non-cardiac origin. The numbers of OHCAs before and after the Kumamoto earthquake were compared using an interrupted time series analysis. The incidence of both cardiac (rate ratio [RR] 1.22) and non-cardiac (RR 1.27) OHCAs in Kumamoto Prefecture increased after the earthquake. The difference disappeared when the analysis was limited to patients with non-cardiac OHCAs with a clear cause of cardiac arrest. The number of cardiac and non-cardiac OHCAs did not increase in other prefectures within the Kyushu region. CONCLUSIONS The Kumamoto earthquake led to an increase in the incidence of cardiac and non-cardiac OHCAs. However, this was attenuated by increasing distance from the epicenter. Except for cardiac causes, cases complicated by earthquake-related events may include non-cardiac OHCAs due to vascular diseases that might be overlooked.

Abstract
Natural disasters, such as floods and landslides caused by heavy rainfall, earthquakes, and tsunamis, can induce stress, which may contribute to the onset and aggravation of various cardiovascular diseases. The circulatory system is most susceptible to the effects of stress, and stress-related cardiovascular diseases, such as Takotsubo cardiomyopathy, pulmonary thromboembolism, hypertension, stroke triggered by increased blood pressure, and acute myocardial infarction, can occur during natural disasters. The risk of developing angina pectoris, arrhythmia, sudden cardiac death, and heart failure increases rapidly and can persist for several months. Moreover, treating cardiovascular diseases is essential during the acute phase, and continuous disease management is necessary during the chronic phase. However, disaster medical care for the victims must be given priority during natural disasters, which may cause a delay in diagnosis or access to necessary treatment for pre-existing medical conditions that could worsen or may cause death in patients with cardiovascular diseases. In this review, we summarize the predisposing factors for cardiovascular diseases that have been obtained through disasters such as major earthquakes and provide potential insights to help medical staff prevent the onset and aggravation of cardiovascular diseases during disasters.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:5058. [PMID: 36981965 PMCID: PMC10049726 DOI: 10.3390/ijerph20065058] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Revised: 03/06/2023] [Accepted: 03/10/2023] [Indexed: 06/18/2023]
Abstract
This retrospective study investigated the 3-year impact of the Great East Japan Earthquake (GEJE) of 2011 on deaths due to neoplasm, heart disease, stroke, pneumonia, and senility among older adults in the primarily affected prefectures compared with other prefectures, previous investigations having been more limited as regards mortality causes and geographic areas. Using death certificates issued between 2006 and 2015 (n = 7,383,253), mortality rates (MRs) and risk ratios (RRs) were calculated using a linear mixed model with the log-transformed MR as the response variable. The model included interactions between the area category and each year of death from 2010 to 2013. The RRs in the interaction significantly increased to 1.13, 1.17, and 1.28 for deaths due to stroke, pneumonia, and senility, respectively, in Miyagi Prefecture in 2011, but did not significantly increase for any of the other areas affected by the GEJE. Moreover, increased RRs were not reported for any of the other years. The risk of death increased in 2011; however, this was only significant for single-year impact. In 2013, decreased RRs of pneumonia in the Miyagi and Iwate prefectures and of senility in Fukushima Prefecture were observed. Overall, we did not find evidence of strong associations between the GEJE and mortality.

Impact of Evacuation on the Long-Term Trend of Metabolic Syndrome after the Great East Japan Earthquake. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19159492. [PMID: 35954851 PMCID: PMC9368087 DOI: 10.3390/ijerph19159492] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/05/2022] [Revised: 07/24/2022] [Accepted: 07/27/2022] [Indexed: 11/17/2022]
Abstract
There has been an increase in lifestyle-related diseases in Fukushima Prefecture since the Great East Japan Earthquake. However, the overall long-term trends of lifestyle-related diseases in the Fukushima Prefecture according to the evacuation and other area are not reported. Therefore, we examined the long-term trends in the prevalence of metabolic syndrome before and after the Great East Japan Earthquake in Fukushima Prefecture according to these areas using a national database. The target population was approximately 330,000–440,000 per year; Fukushima Prefecture residents aged 40–74 years who underwent specific health check-ups during 2008–2017 participated in the study. Fukushima was divided into mountainous, central, coastal and evacuation areas. Using the Poisson regression model, the prevalence of metabolic syndrome in each fiscal year was determined by gender and age group for each location and compared before and after the disaster as well as between areas. Prevalence increased significantly throughout the observation period, particularly in the evacuation area. Age- and gender-adjusted prevalence rates significantly increased from 16.2% in 2010 to 19.5% in 2012 (prevalence ratios = 1.21) and 20.4% in 2017 in the evacuation area. Among other areas, coastal areas showed the highest increase with 17.9% (2017), followed by central areas with 16.5% (2017) and mountainous areas with 18.3% (2016). These increases were particularly high among men and the elderly. The prevalence of metabolic syndrome increased rapidly after the disaster, especially in evacuation area, and continued for subsequent 6–7 year. Long-term monitoring and measures to prevent lifestyle-related diseases are needed after major disasters, especially in evacuation areas, among men and the elderly.

Anger recall mental stress decreases 123I-metaiodobenzylguanidine ( 123I-MIBG) uptake and increases heterogeneity of cardiac sympathetic activity in the myocardium in patients with ischemic cardiomyopathy. J Nucl Cardiol 2022; 29:798-809. [PMID: 33034036 DOI: 10.1007/s12350-020-02372-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2020] [Revised: 08/28/2020] [Accepted: 08/31/2020] [Indexed: 11/28/2022]
Abstract
BACKGROUND Acute psychological stressors such as anger can precipitate ventricular arrhythmias, but the mechanism is incompletely understood. Quantification of regional myocardial sympathetic activity with 123I-metaiodobenzylguanidine (123I-mIBG) SPECT imaging in conjunction with perfusion imaging during mental stress may identify a mismatch between perfusion and sympathetic activity that may exacerbate a mismatch between perfusion and sympathetic activity that could create a milieu of increased vulnerability to ventricular arrhythmia. METHODS Five men with ischemic cardiomyopathy (ICM), and five age-matched healthy male controls underwent serial 123I-mIBG and 99mTc-Tetrofosmin SPECT/CT imaging during an anger recall mental stress task and dual isotope imaging was repeated approximately 1 week later during rest. Images were reconstructed using an iterative reconstruction algorithm with CT-based attenuation correction. The mismatch of left ventricular myocardial 123I-mIBG and 99mTc-Tetrofosmin was assessed along with radiotracer heterogeneity and the 123I-mIBG heart-to-mediastinal ratios (HMR) were calculated using custom software developed at Yale. RESULTS The hemodynamic response to mental stress was similar in both groups. The resting-HMR was greater in healthy control subjects (3.67 ± 0.95) than those with ICM (3.18 ± 0.68, P = .04). Anger recall significantly decreased the HMR in ICM patients (2.62 ± 0.3, P = .04), but not in normal subjects. The heterogeneity of 123I-mIBG uptake in the myocardium was significantly increased in ICM patients during mental stress (26% ± 8.23% vs. rest: 19.62% ± 9.56%; P = .01), whereas the 99mTc-Tetrofosmin uptake pattern was unchanged. CONCLUSION Mental stress decreased the 123I-mIBG HMR, increased mismatch between sympathetic activity and myocardial perfusion, and increased the heterogeneity of 123I-mIBG uptake in ICM patients, while there was no significant change in myocardial defect size or the heterogeneity of 99mTc-Tetrofosmin perfusion. The changes observed in this proof-of-concept study may provide valuable information about the trigger-substrate interaction and the potential vulnerability for ventricular arrhythmias.

Abstract
OBJECTIVES Nursing home residents are especially vulnerable to adverse outcomes after a hurricane. Prior research suggests that emergency department (ED) visits increase among community-residing older adults after natural disasters. However, little is known about the impact of hurricanes on the large population of older adults residing in assisted living (AL) settings, particularly the influence of storms on the rates and causes of ED visits. We examined whether rates of ED use for injuries and other medical reasons increased after Hurricane Irma in 2017 among AL residents in Florida. DESIGN Retrospective cohort study. SETTING AND PARTICIPANTS Samples of 30,358 Medicare fee-for-service beneficiaries in 2016 and 28,922 beneficiaries in 2017 who resided in Florida AL communities. MEASURES The number of injury-related and other medical visits per 1,000 person-days within 30 and 90 days of September 1 in 2016 and 2017. We adjusted for age, race, sex, and chronic conditions using linear regression with AL fixed effects. We compared the top 10 primary diagnoses resulting in an ED visit between 2016 and 2017. RESULTS Adjusted rates of injury-related visits were 12.5% higher at 30 days but did not differ at 90 days. Other medical visits were 12% higher at 30 days in 2017 than in 2016 and 7.7% higher at 90 days. Heart failure was a leading cause of ED visits within 90 days of September 1 in 2017, unlike in 2016. CONCLUSIONS AND IMPLICATIONS Increased attention should be paid to AL communities in disaster preparedness and response efforts given the increased likelihood of ED visits following a hurricane.

Association between Psychological Factors and Evacuation Status and the Incidence of Cardiovascular Diseases after the Great East Japan Earthquake: A Prospective Study of the Fukushima Health Management Survey. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17217832. [PMID: 33114634 PMCID: PMC7663529 DOI: 10.3390/ijerph17217832] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Revised: 10/19/2020] [Accepted: 10/20/2020] [Indexed: 12/28/2022]
Abstract
Evidence regarding the effect of psychological factors and evacuation on cardiovascular disease occurrence after large-scale disasters is limited. This prospective study followed up a total of 37,810 Japanese men and women aged 30–89 years from the Fukushima Prefecture with no history of stroke or heart disease at baseline (2012), until 2017. This period included 3000 cardiovascular events recorded through questionnaires and death certificates. The participants’ psychological distress, trauma reaction, and evacuation status were defined, and divided into four groups based on combinations of psychological factors and evacuation status. We calculated the hazard ratios and 95% confidence intervals for only psychological, only evacuation, or both of them compared with neither using Cox proportional hazard models. Psychological factors along with evacuation resulted in approximately 5% to 25% higher magnitude of stroke and heart disease risk than psychological factors only among men. Compared to neither, the multivariable hazard ratios of those with both psychological distress and evacuation were 1.75 for stroke and 1.49 for heart disease, and those of both trauma reaction and evacuation were 2.01 and 1.57, respectively, among men. Evacuation combined with psychological factors increased the risk of stroke and heart disease risks especially in men after the Great East Japan Earthquake.

Abstract
Aim After the Great East Japan Earthquake, over 160,000 residents in Fukushima Prefecture were forced to evacuate the area around the Fukushima Daiichi power plant following nuclear accident there. Health problems in these evacuees have since become a major issue. We have examined the association between evacuation and incidence of hyperuricemia among residents in Fukushima. Methods We conducted a cohort study of residents aged 40–90 years without hyperuricemia at the time of the Fukushima disaster. Among 8173 residents who met the inclusion criteria before the disaster, 4789 residents (men: 1971, women: 2818; follow-up duration: 1.38 years; and follow-up rate: 58.6%) remained available for follow-up examinations at the end of March 2013. The main endpoint was incidence of hyperuricemia, defined by the Japanese committee guidelines, using local health data from before and after the disaster. We divided participants by evacuation status and compared outcomes between groups. Using a logistic regression model, we estimated the odds ratio for incidence of hyperuricemia, adjusting for potential confounders, age, gender, waist circumference, physical activity, and alcohol consumption. Results Incidence of hyperuricemia was higher in evacuees (men 10.1%; women 1.1%) than in non-evacuees (men 7.4%, women 1.0%). Evacuees had higher body mass index, waist circumference, triglycerides, LDL-cholesterol, fasting plasma glucose, HbA1c, and lower HDL-cholesterol after the disaster than non-evacuees. We found that evacuation was associated with incidence of hyperuricemia (adjusted odds ratio: 1.38; 95% confidence interval: 1.03–1.86). Conclusion This is the first study to demonstrate an association between evacuation after a disaster and increased incidence of hyperuricemia.

Abstract
On March 11, 2011, a great earthquake, known as the Great East Japan Earthquake, hit northeastern Japan, resulting in a tsunami that caused a nuclear disaster, the Fukushima Daiichi Nuclear Power Plant accident, forcing about 160,000 people to evacuate. We, therefore, sought to examine the effects of this evacuation on the onset of cardiovascular diseases and sudden death (SD) in Fukushima Prefecture, three years after the earthquake. We divided the evacuation zone into two areas, whole evacuation zone (Area 1) and partial evacuation zone (Area 2), and we defined the north district of the prefecture as the control area (Area 3). We cross-referenced the death certificate data with data from the Fukushima Prefecture acute myocardial infarction registration survey. For each area, we tallied the number of people who fell into the SD, myocardial infarction (MI), and MI suspected groups. We calculated the age-adjusted incidence rates and analyzed the differences in the adjusted incidence rates across three years using a Poisson regression model. The age-adjusted death rate of the SD group was significantly higher in 2011 in all areas than in 2012 or 2013 (P < 0.05). The total death rate was higher in Area 1 in March 2011, just after the disaster, than in the other two areas. The rate of SD was also higher in Area 1 than in the other areas in March 2011. The incidence of sudden cardiac death might have increased just after the Great East Japan Earthquake in the evacuation area, but not in other areas in Fukushima Prefecture.

Arrhythmic Risk in Elderly Patients Candidates to Transcatheter Aortic Valve Replacement: Predictive Role of Repolarization Temporal Dispersion. Front Physiol 2019; 10:991. [PMID: 31447689 PMCID: PMC6691061 DOI: 10.3389/fphys.2019.00991] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2019] [Accepted: 07/18/2019] [Indexed: 12/30/2022] Open
Abstract
Background/Aim Degenerative aortic valve stenosis (AS) is associated to ventricular arrhythmias and sudden cardiac death, as well as mental stress in specific patients. In such a context, substrate, autonomic imbalance as well as repolarization dispersion abnormalities play an undoubted role. Aim of the study was to evaluate the increase of premature ventricular contractions (PVC) and complex ventricular arrhythmias during mental stress in elderly patients candidate to the transcatheter aortic valve replacement (TAVR). Methods In eighty-one elderly patients with AS we calculated several short-period RR- and QT-derived variables at rest, during controlled breathing and during mild mental stress, the latter being represented by a mini-mental state evaluation (MMSE). Results All the myocardial repolarization dispersion markers worsened during mental stress (p < 0.05). Furthermore, during MMSE, low frequency component of the RR variability increased significantly both as absolute power (LFRR) and normalized units (LFRRN U) (p < 0.05) as well as the low-high frequency ratio (LFRR/HFRR) (p < 0.05). Eventually, twenty-four (30%) and twelve (15%) patients increased significantly PVC and, respectively, complex ventricular arrhythmias during the MMSE administration. At multivariate logistic regression analysis, the standard deviation of QTend (QTesd), obtained at rest, was predictive of increased PVC (odd ratio: 1.54, 95% CI 1.14-2.08; p = 0.005) and complex ventricular arrhythmias (odd ratio: 2.31, 95% CI 1.40-3.83; p = 0.001) during MMSE. The QTesd showed the widest sensitive-specificity area under the curve for the increase of PVC (AUC: 0.699, 95% CI: 0.576-0.822, p < 0.05) and complex ventricular arrhythmias (AUC: 0.801, 95% CI: 0.648-0.954, p < 0.05). Conclusion In elderly with AS ventricular arrhythmias worsened during a simple cognitive assessment, this events being a possible further burden on the outcome of TAVR. QTesd might be useful to identify those patients with the highest risk of ventricular arrhythmias. Whether the TAVR could led to a QTesd reduction and, hence, to a reduction of the arrhythmic burden in this setting of patients is worthy to be investigated.

Abstract
Background Sumo wrestling is a demanding sport. Although watching sumo wrestling may have cardiovascular effects, no studies of this relationship have been performed. Thus, we aimed to evaluate the association between sumo wrestling tournaments and the rate of out‐of‐hospital cardiac arrests. Methods and Results We counted the daily number of patients aged 18 to 110 years who had an out‐of‐hospital cardiac arrest of presumed‐cardiac origin in the Tokyo metropolis between 2005 and 2014. A Poisson regression was used to model out‐of‐hospital cardiac arrests of presumed‐cardiac origin per day. Exposure days were the days on which a sumo tournament was held and broadcast, whereas control days were all other days. Events that occurred on exposure days were compared with those that occurred on control days. Risk ratios for out‐of‐hospital cardiac arrests on Grand Sumo tournaments days compared with control days were estimated. In total, 71 882 out‐of‐hospital cardiac arrests met the inclusion criteria. We recorded a 9% increase in the occurrence of out‐of‐hospital cardiac arrests on the day of a sumo tournament compared with control days. In patients aged 75 to 110 years, we found a 13% increase in the occurrence of out‐of‐hospital cardiac arrests on the day of a sumo tournament compared with control days. Conclusions We found a significant increase in the occurrence of out‐of‐hospital cardiac arrests on the days of sumo tournaments compared with control days in the Tokyo metropolis between 2005 and 2014. Further studies are needed to verify these initial findings on sumo tournaments and cardiovascular events.

Abstract
BACKGROUND We assessed whether the occurrence of out-of-hospital cardiac arrest (OHCA) with cardiac origin increased in the disaster areas during the 3-year period after the Great East Japan Earthquake (GEJE).Methods and Results:From the OHCA registry in Japan, yearly changes in occurrence after the GEJE were assessed by applying Poisson regression models. The risk ratio of the first year after the earthquake was significantly greater in both men and women, but the difference disappeared in the second and third years. CONCLUSIONS The GEJE significantly increased the occurrence of OHCA with cardiac origin in the first year after the earthquake.

Abstract
Anger and other negative emotions can precipitate sudden death, as shown in studies of population stressors. Clinical studies of patients with implantable defibrillators demonstrate that anger can trigger ventricular arrhythmias. Long-term negative emotions also increase vulnerability to arrhythmias. Mechanisms linking anger and arrhythmias include autonomic changes, which alter repolarization, possibly enhanced in patients with sympathetic denervation, which in turn trigger potentially lethal polymorphic ventricular tachycardias. Interventions which decrease negative emotions and resultant autonomic responses may be therapeutic in patients with implantable cardioverter defibrillators.

Long-Term Effects of the 2011 Japan Earthquake and Tsunami on Incidence of Fatal and Nonfatal Myocardial Infarction. Am J Cardiol 2017; 120:352-358.

Abstract
This study aimed to examine the long-term effects of the 2011 Japan earthquake and tsunami on the incidence of fatal and nonfatal myocardial infarction (MI). In the present study, the incidence of 2 types of cardiac events was comprehensively recorded. The study area was divided into 2 zones based on the severity of tsunami damage, which was determined by the percentage of the inundated area within the residential area (<10%, low-impact zone and ≥10%, high-impact zone). The standardized incidence ratio (SIR) and 95% CI for both types of cardiac events during the disaster year and the postdisaster years were determined in each zone. During the 4-year period after the disaster, the SIRs for nonfatal MI did not change to a statistically significant extent in either zones. For fatal MI, the SIR was stable during the study period in the low-impact zone. However, in the high-impact zone, the SIR was significantly elevated in the disaster year of 2011 (1.80 [95% CI 1.32 to 2.28]), and this increase was sustained for the following 3 years (2012, 2.06 [1.55 to 2.57]; 2013, 1.99 [1.49 to 2.48]; 2014, 2.12 [1.62 to 2.63]). The SIRs for fatal MI for the 4 postdisaster years in the municipal areas were significantly correlated with the percentage of the inundated area (r = 0.83; p <0.001) and the number of deaths due to the tsunami (r = 0.77; p <0.005) but not with the maximum seismic intensity (r = 0.43; p = 0.12). In conclusion, these results suggest that the devastating tsunami was associated with a continual increase in the incidence of fatal MI among disaster survivors.

Heat-Related Mortality in Japan after the 2011 Fukushima Disaster: An Analysis of Potential Influence of Reduced Electricity Consumption. ENVIRONMENTAL HEALTH PERSPECTIVES 2017; 125:077005. [PMID: 28686555 PMCID: PMC5744700 DOI: 10.1289/ehp493] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/11/2016] [Revised: 03/07/2017] [Accepted: 03/13/2017] [Indexed: 05/05/2023]
Abstract
BACKGROUND In March 2011, the Great East Japan Earthquake devastated several power stations and caused severe electricity shortages. This accident was followed by the implementation of policies to reduce summer electricity consumption in the affected areas, for example, by limiting air-conditioning (AC) use. This provided a natural experimental scenario to investigate if these policies were associated with an increase in heat-related mortality. OBJECTIVES We examined whether the reduced electricity consumption in warm season modified heat-related mortality from 2008 to 2012. METHODS We conducted prefecture-specific interrupted time-series (ITS) analyses to compare temperature-mortality associations before and after the earthquake, and used meta-analysis to generate combined effect estimates for the most affected and less affected areas (prefectures with >10% or ≤10% reductions in electricity consumption, respectively). We then examined whether the temperature-mortality association in Tokyo, one of the most affected areas, was modified by the percent reduction in electricity consumption relative to expected consumption for comparable days before the earthquake. RESULTS Contrary to expectations, we estimated a 5-9% reduction in all-cause heat-related mortality after the earthquake in the 15 prefectures with the greatest reduction in electricity consumption, and little change in the other prefectures. However, the percent reduction in observed vs. expected daily electricity consumption after the earthquake did not significantly modify daily heat-related mortality in Tokyo. CONCLUSIONS In the prefectures with the greatest reductions in electricity consumption, heat-related mortality decreased rather than increased following the Great East Japan Earthquake. Additional research is needed to determine whether this finding holds for other populations and regions, and to clarify its implications for policies to reduce the consequences of climate change on health. https://doi.org/10.1289/EHP493.

Abstract
The Great East Japan Earthquake occurred on March 11, 2011, and was followed by a nuclear accident at the Fukushima Daiichi Nuclear Power Plant. The government ordered a mandatory evacuation from the high radioactive concentration area in Fukushima. This evacuation may have forced many evacuees to change specific aspects of their lifestyles such as diet and physical activity, which in turn may lead to future incidence of lifestyle diseases such as cardiovascular diseases (CVDs). To address this concern, the association between the evacuation and changes in CVD risk factors before and after the disaster was examined in the Fukushima Health Management Survey. In the present study, we reviewed the results of longitudinal studies in the Fukushima Health Management Survey. The proportion of overweight/obese people and those with hypertension, diabetes mellitus, dyslipidemia, liver dysfunction, atrial fibrillation, and polycythemia increased after the disaster. Furthermore, the evacuation was associated with an increase of these cardiovascular risk factors. Therefore, evacuees may be more disposed to CVDs such as myocardial infarction and stroke after the disaster. The prevention of future CVDs among evacuees from Fukushima requires ongoing preventive programs for obesity, hypertension, diabetes mellitus, and dyslipidemia, in collaboration with local governments and communities.

Abstract
Objective To investigate the relationship between personal experience of the Great East Japan Earthquake and various disease types among nursery school children. Design We conducted a nationwide survey of nursery school children born between 2 April 2006 and 1 April 2007. Nursery school teachers completed questionnaires if they agreed to join the study. Questionnaire items for children consisted of their birth year and month, sex, any history of moving into or out of the current nursery school, presence of diseases diagnosed by a physician at the age of 66–78 months and type of disaster experience. The survey was conducted from September 2012 to December 2012. Setting Japan, nationwide. Participants A total of 60 270 nursery school children were included in the analysis, 840 of whom experienced the disaster on 11 March 2011. Main outcome measures The health status of children 1.5 years after the disaster based on nursery school records. Results Experiencing the disaster significantly affected the prevalence of overall and individual diseases. Furthermore, there was a difference in disease prevalence between boys and girls. In boys, experiencing the tsunami (OR 2.53, 95% CI 1.22 to 5.24) and living in an evacuation centre (OR 2.92, 95% CI 1.46 to 5.83) were remarkably associated with a higher prevalence of atopic dermatitis, but these trends were not observed among girls. Instead, the home being destroyed (OR 3.50, 95% CI 2.02 to 6.07) and moving house (OR 4.19, 95% CI 2.01 to 8.71) were positively associated with a higher prevalence of asthma among girls. Conclusions Our study indicates that experiencing the disaster may have affected the health status of nursery school children at least up to 1.5 years after the disaster. Continuous monitoring of the health status of children is necessary to develop strategic plans for child health.

Abstract
BACKGROUND We and others have previously reported that the Great East Japan Earthquake (GEJE) caused a significant but transient increase in cardiovascular diseases and deaths in the disaster area. However, it remains to be examined whether the GEJE had a long-term prognostic influence in large-scale cohort studies. This point is important when analyzing the data before and after the GEJE in the cohort studies in the disaster area. METHODS We examined 8676 patients registered in our Chronic Heart Failure Analysis and Registry in the Tohoku District-2 (CHART-2) Study (N=10,219) between 2006 and 2010 and were alive after March 10, 2011. RESULTS There were 48 GEJE-related deaths, causing a sharp and transient increase in all-cause death within a month after the GEJE. However, after excluding the GEJE-related deaths, the cubic polynomial spline smoothing showed no significant increase in all-cause death, heart failure admission, non-fetal acute myocardial infarction, or non-fetal stroke during the median 3-year follow-up after the GEJE. The extrapolation curves beyond the GEJE, which were obtained by the parametric survival models based on the survival data censored on the GEJE, were not significantly different from the Kaplan-Meier curves estimating the survival functions of deaths and cardiac events during the total follow-up period without considering the impacts of the GEJE. Furthermore, the multivariate Cox proportional hazard model applied to the matched cohort of the baseline data and the data after the GEJE showed no significant differences in the impacts of prognostic factors on all-cause mortality before and after the GEJE. CONCLUSIONS These results indicate that the GEJE had no significant long-term prognostic impact after the earthquake in cardiovascular patients in the disaster area.

Abstract
AIM After the Great East Japan Earthquake, over 160,000 residents near the Fukushima Daiichi Nuclear Power Plant were forced to evacuate due to a nuclear accident. Health problems in these evacuees have since become major issues. We examined the association between evacuation and incidence of metabolic syndrome (METS) among residents in Fukushima. METHODS We conducted a cohort study among residents aged 40-74 years without METS at the time of the disaster in Fukushima. Among 20,269 residents who met the inclusion criteria before the disaster, 8,547 residents (3,697 men and 4,850 women; follow-up proportion: 42.2%) remained available for follow-up examinations after the disaster by the end of March 2013. The main outcome was incidence of METS, defined by guidelines from the Japanese committee, using data from the Comprehensive Health Check before and after the disaster. We divided participants by evacuation status and compared outcomes between groups. Using a logistic regression model, we estimated the odds ratio for incidence of METS, adjusting for potential confounders, age, gender, waist circumference, exercise habit, and alcohol consumption. RESULTS Incidence of METS was higher in evacuees (men 19.2%, women 6.6%) than in non-evacuees (men 11.0%, women 4.6%). Evacuees had higher body mass index, waist circumference, triglycerides, and fasting plasma glucose after the disaster than non-evacuees. We found a significant association between evacuation and incidence of METS (adjusted odds ratio 1.72, 95% confidence interval; 1.46-2.02). CONCLUSION This is the first study to demonstrate that evacuation after a disaster is associated with increased incidence of METS.

Abstract
On March 11, 2011, the Great East Japan Earthquake occurred in Japan, with a nuclear accident subsequently occurring at the Fukushima Daiichi Nuclear Power Plant. The disaster forced many evacuees to change particular aspects of their lifestyles. This study assessed the hypothesis that evacuation may have increased the risk of hypertension among residents in Fukushima. A longitudinal study examined data collected from 31 252 Japanese participants aged 40 to 74 years sourced from general health checkups conducted in 13 communities between 2008 and 2010. Follow-up examinations were conducted from 2011 through 2013. A total of 21 989 participants (follow-up proportion, 70.4%) received follow-up examinations. Mean blood pressure significantly increased in both evacuees and nonevacuees after the disaster, with greater changes in blood pressure among the former. The changes in systolic and diastolic blood pressure among the evacuees and nonevacuees were +5.8/3.4 versus +4.6/2.1 mm Hg (
P
<0.01/
P
<0.0001) for men and +4.4/2.8 versus +4.1/1.7 mm Hg (
P
=0.33/
P
<0.0001) for women, respectively. Evacuation was associated with an increased risk of hypertension among men, and the age-adjusted hazard ratios of evacuation for incidence of hypertension were 1.24 (95% confidence interval, 1.11–1.39;
P
<0.001) for men and 1.05 (95% confidence interval, 0.94–1.17;
P
=0.37) for women, respectively. For men, after adjustment for confounding variables, the hazard ratio slightly decreased to 1.20, but the association was essentially unchanged. Blood pressure increased among residents, especially evacuees, in the evacuation zone of Fukushima prefecture after the Great East Japan Earthquake. Evacuation may be associated with an increased risk of hypertension among men in the 2 years after the disaster.

Effect of Evacuation on Body Weight After the Great East Japan Earthquake. Am J Prev Med 2016; 50:553-560. [PMID: 26673483 DOI: 10.1016/j.amepre.2015.10.008] [Citation(s) in RCA: 49] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2015] [Revised: 09/28/2015] [Accepted: 10/11/2015] [Indexed: 10/22/2022]
Abstract
INTRODUCTION The Great East Japan Earthquake occurred on March 11, 2011, with a nuclear accident subsequently occurring at the Fukushima Daiichi Nuclear Power Plant. The government ordered a mandatory evacuation from the high radioactive concentration area in Fukushima, which might have forced many evacuees to change particular aspects of their lifestyles. This study assessed the hypothesis that mean body weight and the proportion of overweight/obese individuals would increase among evacuees after versus before the disaster. METHODS A longitudinal study examined data collected from 41,633 Japanese participants (mean age, 67 years) sourced from general health checkups conducted in 13 communities between 2008 and 2010. Follow-up examinations were conducted from June 2011 through March 2013. RESULTS A total of 27,486 participants (12,432 men and 15,054 women; follow-up proportion, 66%) received follow-up examinations after the disaster, with an average follow-up of 1.6 years. Mean body weight significantly increased in both evacuees (n=9,671) and non-evacuees (n=17,815) after the disaster, with greater changes in body weight among evacuees than non-evacuees (+1.2 kg vs +0.3 kg, p<0.001). The proportion of overweight/obese people also increased among evacuees after the disaster, and evacuation was associated with an increased risk of being overweight, despite adjustments for confounding variables. The proportions of overweight evacuees before and after the disaster were 31.8% and 39.4%, respectively, whereas proportions among non-evacuees were 28.3% and 30.3%, respectively. CONCLUSIONS Body weight and the proportion of overweight/obese people increased among residents, especially evacuees, in the evacuation zone of Fukushima prefecture after the Great East Japan Earthquake.

Abstract
AIM: To identify patient, cardiac arrest and management factors associated with hospital survival in comatose survivors of cardiac arrest.
METHODS: A retrospective, single centre study of comatose patients admitted to our intensive care unit (ICU) following cardiac arrest during the twenty year period between 1993 and 2012. This study was deemed by the Human Research Ethics Committee (HREC) of Monash Health to be a quality assurance exercise, and thus did not require submission to the Monash Health HREC (Research Project Application, No. 13290Q). The study population included all patients admitted to our ICU between 1993 and 2012, with a discharge diagnosis including “cardiac arrest”. Patients were excluded if they did not have a cardiac arrest prior to ICU admission (i.e., if their primary arrest was during their admission to ICU), or were not comatose on arrival to ICU. Our primary outcome measure was survival to hospital discharge. Secondary outcome measures were ICU and hospital length of stay (LOS), and factors associated with survival to hospital discharge.
RESULTS: Five hundred and eighty-two comatose patients were admitted to our ICU following cardiac arrest, with 35% surviving to hospital discharge. The median ICU and hospital LOS was 3 and 5 d respectively. There was no survival difference between in-hospital and out-of-hospital cardiac arrests. Males made up 62% of our cardiac arrest population, were more likely to have a shockable rhythm (56% vs 37%, P < 0.001), and were more likely to survive to hospital discharge (40% vs 28%, P = 0.006). On univariate analysis, therapeutic hypothermia, regardless of method used (e.g., rapid infusion of ice cold fluids, topical ice, “Arctic Sun”, passive rewarming, “Bair Hugger”) and location initiated (e.g., pre-hospital, emergency department, intensive care) was associated with increased survival. There was however no difference in survival associated with target temperature, time at target temperature, location of initial cooling, method of initiating cooling, method of maintaining cooling or method of rewarming. Patients that survived were more likely to have a shockable rhythm (P < 0.001), shorter time to return of spontaneous circulation (P < 0.001), receive therapeutic hypothermia (P = 0.03), be of male gender (P = 0.006) and have a lower APACHE II score (P < 0.001). After multivariate analysis, only a shockable initial rhythm (OR = 6.4, 95%CI: 3.95-10.4; P < 0.01) and a shorter time to return of spontaneous circulation (OR = 0.95, 95%CI: 0.93-0.97; P < 0.01) was found to be independently associated with survival to hospital discharge.
CONCLUSION: In comatose survivors of cardiac arrest, shockable rhythm and shorter time to return of spontaneous circulation were independently associated with increased survival to hospital discharge.

Predictors of Hypertension in Survivors of the Great East Japan Earthquake, 2011: A Cross-sectional Study. Prehosp Disaster Med 2016; 31:17-26.

Abstract
AbstractIntroductionMany survivors of a major disaster die shortly after the event. Hypertension (HT) is one of the most important risk factors for these disaster-related diseases. An urgent need exists to establish methods to detect disaster survivors with HT and start medication immediately, as those with no injuries or symptoms may not be examined and medical teams cannot measure all survivors’ blood pressure (BP) because they often do not have sufficient time.ObjectiveThe goals of this report were: (1) to evaluate the importance of taking antihypertensive drugs continuously for patients with HT during the sub-acute phase after a major earthquake, when patients cannot attend a clinic because of destruction of the local infrastructure; and (2) to establish simple and reliable predictors to detect evacuees with HT, who require clinical examination and treatment at evacuation shelters or in their homes after a major earthquake.MethodsMedical rounds were performed at evacuation shelters in Iwate Prefecture after the Great East Japan Earthquake. Forty evacuees were enrolled in a cross-sectional study. The effect of taking antihypertensive drugs continuously was evaluated and predictors of HT in evacuees were identified using multiple logistic regression analysis.ResultsTwenty-eight evacuees were hypertensive (70%), nine of whom were asymptomatic (32%). Most evacuees who had discontinued antihypertensive medication (92%; 11/12) had very high BP, while those who had continued antihypertensive medication (80%; 8/10) were mildly hypertensive. The systolic BP of those who had discontinued antihypertensive drugs was significantly higher than that of those who had continued hypertensive drugs in the whole cohort (n=40), and also in evacuees diagnosed as having HT at evacuation shelters (n=28; P<.01 for both comparisons). A history of HT (adjusted odds ratio [aOR], 11.40; 95% confidence interval [CI], 1.03-126.08) or age >55 years (aOR, 1.10; 95% CI, 1.01-1.21) predicted HT with a sensitivity of 0.96 and specificity of 0.80.ConclusionsThe results of this study suggest that continuity of antihypertensive medication prevents serious HT at evacuation shelters in the first 10 days after a major earthquake. Onsite medical rounds focusing on simple predictors in an early stage after disasters may be an effective means of detecting and treating hypertensive disaster victims before they succumb to a fatal disease.TanakaR, OkawaM, UjikeY.

Abstract
Sudden cardiac death (SCD) from cardiac arrest is a major international public health problem accounting for an estimated 15%-20% of all deaths. Although resuscitation rates are generally improving throughout the world, the majority of individuals who experience a sudden cardiac arrest will not survive. SCD most often develops in older adults with acquired structural heart disease, but it also rarely occurs in the young, where it is more commonly because of inherited disorders. Coronary heart disease is known to be the most common pathology underlying SCD, followed by cardiomyopathies, inherited arrhythmia syndromes, and valvular heart disease. During the past 3 decades, declines in SCD rates have not been as steep as for other causes of coronary heart disease deaths, and there is a growing fraction of SCDs not due to coronary heart disease and ventricular arrhythmias, particularly among certain subsets of the population. The growing heterogeneity of the pathologies and mechanisms underlying SCD present major challenges for SCD prevention, which are magnified further by a frequent lack of recognition of the underlying cardiac condition before death. Multifaceted preventative approaches, which address risk factors in seemingly low-risk and known high-risk populations, will be required to decrease the burden of SCD. In this Compendium, we review the wide-ranging spectrum of epidemiology underlying SCD within both the general population and in high-risk subsets with established cardiac disease placing an emphasis on recent global trends, remaining uncertainties, and potential targeted preventive strategies.

Abstract
BACKGROUND The 2011 Great Japan tsunami and nuclear leaks displaced 300 000 people, but there are no large studies of psychological distress suffered by these refugees. AIMS To provide a first assessment of major factors associated with distress and dysfunctional behaviour following the disasters. METHOD All refugee families living in Miyagi were sent a questionnaire 10-12 months after the disasters. 21 981 participants (73%) returned questionnaires. Questions assessed psychological distress (Kessler Psychological Distress Scale, K6), dysfunctional behaviours, demographics, event exposure, change in physical activity, household visitors and emotional support. RESULTS Nine percent scored 13+ on the K6 indicating risk of severe mental illness. Psychological distress was greater among Fukushima refugees. Demographic variables, family loss, illness history and change in physical activity were associated with psychological distress and dysfunctional behaviours. Associations between psychological distress and dysfunction and visitors/supporters depended on relation to supporter. CONCLUSIONS Practitioners need to recognise existing disease burden, community histories and family roles when intervening following disasters. DECLARATION OF INTEREST None.

Burden of cardiovascular morbidity and mortality following humanitarian emergencies: a systematic literature review. Prehosp Disaster Med 2014; 30:80-8.

Abstract
BACKGROUND The global burden of cardiovascular mortality is increasing, as is the number of large-scale humanitarian emergencies. The interaction between these phenomena is not well understood. This review aims to clarify the relationship between humanitarian emergencies and cardiovascular morbidity and mortality. METHODS With assistance from a research librarian, electronic databases (PubMed, Scopus, CINAHL, and Global Health) were searched in January 2014. Findings were supplemented by reviewing citations of included trials. Observational studies reporting the effect of natural disasters and conflict events on cardiovascular morbidity and mortality in adults since 1997 were included. Studies without a comparison group were not included. Double-data extraction was utilized to abstract information on acute coronary syndrome (ACS), acute decompensated heart failure (ADHF), and sudden cardiac death (SCD). Review Manager 5.0 (Version 5.2, The Nordic Cochrane Centre; Copenhagen Denmark,) was used to create figures for qualitative synthesis. RESULTS The search retrieved 1,697 unique records; 24 studies were included (17 studies of natural disasters and seven studies of conflict). These studies involved 14,583 cardiac events. All studies utilized retrospective designs: four were population-based, 15 were single-center, and five were multicenter studies. Twenty-three studies utilized historical controls in the primary analysis, and one utilized primarily geographical controls. DISCUSSION Conflicts are associated with an increase in long-term morbidity from ACS; the short-term effects of conflict vary by study. Natural disasters exhibit heterogeneous effects, including increased occurrence of ACS, ADHF, and SCD. CONCLUSIONS In certain settings, humanitarian emergencies are associated with increased cardiac morbidity and mortality that may persist for years following the event. Humanitarian aid organizations should consider morbidity from noncommunicable disease when planning relief and recuperation projects.

Abstract
BACKGROUND To examine changes in the incidence of out-of-hospital cardiac arrest (OHCA) with cardiac origin in the non-disaster areas of Japan before and after the Great East Japan Earthquake of 11 March 2011. METHODS The 35 prefectures in Japan with no dead or missing caused directly by the earthquake were defined as the non-disaster areas. Data of adult OHCA patients in the non-disaster areas from March 4 to 24 each year from 2005 to 2011 were obtained from the All-Japan Utstein Registry. Risk ratios (RRs) of OHCA incidence and 95% CIs were estimated for three specific weeks in 2011 (1 week before and 2 weeks after the earthquake) by applying multivariable Poisson regression model. Incidence in the corresponding periods of March 4-24 from 2005 to 2010 was set as the baseline risk. RESULTS In the analyses from a total of 17,353 OHCA patients, the incidence statistically significantly increased in the first week after the earthquake in all adults (adjusted-RR=1.13, 95% CI=1.05 to 1.22, p=0.001) and in elderly women (adjusted-RR=1.23, 95% CI=1.11 to 1.37, p<0.001). CONCLUSIONS The Great East Japan Earthquake caused the increase of OHCA among elderly women even in the non-disaster areas.

Abstract
OBJECTIVE The incidence of cardiovascular disease (CVD) reportedly increases following a huge disaster. On March 11, 2011, the Great East Japan Earthquake hit a large area of eastern Japan. In Fukushima prefecture, many people suffered from the consequences of the earthquake, the subsequent tsunami, and especially the Fukushima Daiichi Nuclear Power Plant accident. We assessed whether the incidence of acute myocardial infarction (AMI) increased after the earthquake. METHODS We enrolled AMI patients admitted to 36 hospitals in Fukushima prefecture between March 11, 2009, and March 10, 2013 (n = 3068). We compared the incidence of AMI after the earthquake for more than 3 months and 1 year with that in the control years. RESULTS The incidence of Fukushima's annual AMI patients (per 100 000 persons) in 2011 was similar to that of previous years (n = 38.9 [2011] vs 37.2 [2009] and 38.5 [2010], P = .581). However, a significantly higher incidence of AMI was found in the Iwaki district after the disaster that corresponded to the 1-year period of observation (n = 38.7 [2011] vs 27.3 [2009] and 32.8 [2010], P = .045). CONCLUSION The Great East Japan Earthquake affected the incidence of AMI only in limited areas of Fukushima prefecture.
