Clinical Features of Patients With Heart Failure After the 2016 Kumamoto Earthquakes.

ABSTRACT

OBJECTIVE: Acute and chronic stress after severe earthquakes can contribute to cardiovascular events, including heart failure (HF). On April 14, 2016, magnitude 7 earthquakes occurred in the Aso region in the western part of Japan. This study aimed to investigate the clinical characteristics of HF in this area after these earthquakes. METHODS: We investigated the clinical characteristics and 1-y mortality rate of patients with HF. Nutritional status was evaluated with the Geriatric Nutritional Risk Index (GNRI) and the Prognostic Nutritional Index (PNI). RESULTS: Among a total of 58 cardiovascular events, HF was the most frequently observed (n = 28). The mean age of individuals with HF was 85.5 y. The total incidence of HF was significantly higher compared with the average of the prior 2 y. Disaster influence on mental health was suggested by patient history in 20 patients (71%). The 1-y mortality rate among patients with HF was 50%. Among those who died, 93% had malnutrition status (GNRI <92 and /or PNI ≤38). CONCLUSIONS: Our results demonstrated the poor prognosis of patients with HF following the disaster. The prevalence of malnutrition was high in those patients. Careful follow-up is necessary, especially for older people with frailty.
