翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Takotsubo cardiomyopathy ： ウィキペディア英語版 Takotsubo cardiomyopathy Takotsubo cardiomyopathy, also known as transient apical ballooning syndrome, apical ballooning cardiomyopathy, stress-induced cardiomyopathy, Gebrochenes-Herz-Syndrom, and stress cardiomyopathy is a type of non-ischemic cardiomyopathy in which there is a sudden temporary weakening of the muscular portion of the heart. Because this weakening can be triggered by emotional stress, such as the death of a loved one, a break-up, or constant anxiety, it is also known as broken-heart syndrome. Stress cardiomyopathy is a well-recognized cause of acute heart failure, lethal ventricular arrhythmias, and ventricular rupture. ==Signs and symptoms== The typical presentation of takotsubo cardiomyopathy is a sudden onset of congestive heart failure associated with ECG changes mimicking a myocardial infarction of the anterior wall. During the course of evaluation of the patient, a bulging out of the left ventricular apex with a hypercontractile base of the left ventricle is often noted. It is the hallmark bulging out of the apex of the heart with preserved function of the base that earned the syndrome its name "tako tsubo", or octopus pot in Japan, where it was first described. Stress is the main factor in takotsubo cardiomyopathy, with over 85% of cases are set in motion by either a physically or emotionally stressful event that prefaces the start of symptoms.〔Sharkey, S., Lesser, J., & Maron, B. (2011). Takotsubo (stress) cardiomyopathy. American Heart Association. Retrieved from http://circ.ahajournals.org/content/124/18/e460.full〕 Examples of emotional stressors may include grief from the death of a loved one, fear from public speaking, arguing with a spouse, relationship disagreements, betrayal or financial problems.〔 Acute asthma, surgery, chemotherapy, and stroke are examples of physical stressors.〔 Takotsubo cardiomyopathy is more commonly seen in postmenopausal women. Often there is a history of a recent severe emotional or physical stress.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Takotsubo cardiomyopathy」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
