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.
