See the press release:Munich, Germany – August 27 2012: The Japanese earthquake and tsunami of 11 March 2011, which hit the north-east coast of Japan with a magnitude of 9.0 on the Richter scale, was one of the largest ocean-trench earthquakes ever recorded in Japan. The tsunami caused huge damage, including 15,861 dead and 3018 missing persons, and, as of 6 June 2012, 388,783 destroyed homes...Read more

AimsWhile previous studies reported short-term increase in individual cardiovascular disease (CVD) after great earthquakes, mid-term occurrences of all types of CVDs after great earthquakes are unknown. We addressed this important issue in our experience with the Great East Japan Earthquake (March 11, 2011).
Methods and ResultsWe retrospectively examined the impact of the Earthquake on the occurrences of CVDs and pneumonia by comparing the ambulance records made by doctors in our Miyagi prefecture, the center of the disaster area, during the periods of 2008-2011 (n=124,152). The weekly occurrences of CVDs, including heart failure (HF), acute coronary syndrome (ACS), stroke and cardiopulmonary arrest (CPA), and pneumonia were all significantly increased after the Earthquake compared with the previous 3 years. The occurrences of ACS and CPA showed the rapid increase followed by a sharp decline, whereas those of HF and pneumonia showed a prolonged increase for more than 6 weeks and those of stroke and CPA showed a second peak after the largest aftershock (April 7, 2011). Furthermore, the occurrence of CPA was increased in the first 24 hours after the Earthquake, followed by other diseases later on. These increases were independent of age, sex or residence area (seacoast vs. inland).
ConclusionsThese results indicate that the occurrences of all types of CVDs and pneumonia were increased in somewhat different time-courses after the Earthquake, including the first observation of the marked and prolonged increase in HF, emphasizing the importance of intensive medical management of all types of CVDs after great earthquakes.
