Abstract

<abstract abstract-type="author" id="abs0005"> <title id="sect0005">Abstract</title> <sec> <title id="sect0010">Background</title> <p id="spar0005">On July 12, 2012, heavy rains struck southwest Japan, particularly in the Mount Aso area. Huge mud slides in the mountains destroyed houses, and heavy rains caused severe flooding in the inhabited areas. We investigated the incidence of cardiovascular events after the disaster.</p> </sec> <sec> <title id="sect0015">Methods</title> <p id="spar0010">We investigated patients who were admitted to the emergency department (ED) from July 12 to August 31 in 2012. We reviewed all patients with cardiovascular events, including acute myocardial infarction (AMI), angina attack, worsening of congestive heart failure (CHF), cardiopulmonary arrest (CPA), arrhythmias, tako-tsubo cardiomyopathy (TC), and symptomatic venous thromboembolism (VTE).</p> </sec> <sec> <title id="sect0020">Results</title> <p id="spar0015">The total number of cardiovascular events was 28 (14 supraventricular arrhythmias, 3 angina attacks, 1 AMI, 1 VTE, 4 CHF, 1 TC and 4 CPA). There was a significant increase in cardiovascular events during the follow-up period in 2012 in comparison with the average number of these events over the same time period during the prior 2 years (16.8 vs. 5.1/month, <italic>p</italic> < 0.01). There was a sharp increase in cardiovascular events in the first week after the disaster. A second peak was observed 7 weeks after the disaster. Two patients with angina attack were previously diagnosed as having vasospastic angina. The incidence rate of AMI did not increase.</p> </sec> <sec> <title id="sect0025">Conclusion</title> <p id="spar0020">An increase in cardiovascular events was observed after severe rainfalls and mud slides. Prevention of disaster-induced cardiovascular events should be a priority regardless of the magnitude of the disaster.</p> </sec> </abstract>
