Hypertension treatment status and ultrasonic cardiography findings in temporary housing residents after the Kumamoto earthquake: a cross-sectional study

Background: We aimed to investigate and report the relationship between hypertension treatment status and cardiac functions among temporary housing residents after the Kumamoto earthquake. Material and methods: Ultrasonic cardiography examinations were conducted for 56 residents at temporary housing complexes in Minami Aso village in Kumamoto Prefecture in December 2016. The subjects were divided into the following three groups according to the incidence of hypertension and the antihypertensive treatment status: normal (without hypertension), treated, and untreated. Subsequently, their cardiac functions were compared. Results: Age and BMI were found to be positive predictors for hypertension. Moreover, age, LAVI, and LVMI tended to be higher in the untreated group than in the treated group. Moderate or severe mitral regurgitation was significantly more common in the untreated group than in the treated group. Conclusions: Controlling blood pressure may help to prevent new cardiac diseases (e.g., valve regurgitation) among survivors after a major disaster. In addition, for survivors who are  severely affected by psychological stress, improving the mental stress support system may be an effective measure to reduce health problems

Deep-vein thrombosis detection rates and consideration of the living environment in a tsunami disaster area during the disaster reconstruction phase: A cross-sectional study

Introduction: Tsunami victims of the Great East Japan Earthquake were screened for deep-vein thrombosis(DVT) in order to compare the DVT incidence rates between temporary and non-temporary housing residentgroups. Material and methods: Lower extremity venous ultrasonography was performed on 290 subjects (64 menand 226 women; mean age = 71.9 ± 7.9 years) at 44 months after the disaster. All subjects completedquestionnaires to gather information about their background factors which included the Kessler PsychologicalDistress Scale: K6. Results: The DVT detection rate was 10.7% in the temporary group. In the non-temporary group, it was 11.3%among the subjects who previously lived in temporary housing. For the subjects who were living in their own homes it was 9.2%. Psychological distress levels measured by K6 were significantly higher in the temporary housinggroup than in the non-temporary housing group. The multivariate analysis showed that the background factorassociated with DVT risk was SV (soleal vein) dilatation in all subjects as well as in the non-temporary housinggroup, while hypertension and use of sleeping pills were found to be the factors in the temporary housing group. Conclusions: DVT detection rates were similar between the temporary and non-temporary housing groups,and were higher than that in the Japanese general population. The psychological distress level of the tsunamivictims measured by K6 was also higher in the temporary housing group than in the non-temporary housinggroup. It is necessary to establish a long-term and awareness-raising disaster victim support system

Ultrasound cardiography examinations detect victims’ long-term realized and potential consequences after major disasters: a case-control study

Abstract Background An increase in cardiovascular diseases has been reported following major disasters. Previous work has shown that ultrasonographic findings from ultrasound cardiography examination (UCG) increased until the 44th month after the tsunami caused by the Great East Japan Earthquake. The present study conducted UCG among victims in the tsunami disaster area and investigated the frequency of disaster-related cardiovascular diseases and changes over time until the 55th month after the disaster. Methods The subjects were residents of temporary housing complexes and neighboring housing in Watari-gun, Miyagi Prefecture, Japan. There were 207 subjects in the 18th month, 125 in the 30th month, 121 in the 44th month, and 106 in the 55th month after the disaster. Data were collected through UCG and self-report questionnaire. Results Significant changes were observed among subjects with clinical findings from the UCG, which increased over the study period—from 42.0 to 60.8, 72.7, and 73.6% beginning in the 18th month after the disaster (p < 0.0001). Conclusions It is possible that the UCG can become a useful examination to visualize the potential impact of a major disaster on the cardiac function of victims. Victims with clinical findings continued increasing not only during the acute phase after a disaster but also in the long term. We therefore need to keep this in mind, and note that it is important to establish a support system to control cardiovascular diseases from the early stage of disaster.
