Fig. 2. A, weekly incidents of newly referred patients with myocardial infarction before and after the earthquake. The admission rate was about 3.5-fold increased during the 4 weeks immediately after the disaster, compared with the mean incidence for each week of the previous 3 years. B, D-dimer levels were significantly increased 1 to 2 weeks after the earthquake, indicating activation of the coagulation cascade in response to the disaster. (Redrawn from Matsuo et al.
