According to the last available data TTS may represent 2% of all admissions for acute coronary syndromes. Despite the reliable prevalence, diagnosis of TTS remains difficult. The initial presentation, both clinically and electrocardiographically, is similar to an acute myocardial infarction (AMI). The biomarker profile is also similar, although the peaks of troponin and creatinine kinase levels are lower, and brain natriuretic peptide levels are higher in patients with TTS compared with ST-segment elevation AMI. Modified Mayo diagnostic criteria are the most common for the diagnosis. Pathogenesis of TTS currently is not well understood. Catecholamines appear to play a central role in the pathophysiology of TTS. However, it is conceivable that some people have a genetic predisposition to stress-induced TTS. A genetic predisposition has been suggested based on the few familial TTS cases described. Despite reversible myocardial dysfunction, acute heart failure is the most common complication in the acute phase of TTS. In-hospital mortality rate is comparable to that of ST-segment elevation AMI. There are no randomized clinical trials to support specific treatment recommendations in TTS. It is believed that the tactics of managing patients with TTS hospitalized with suspicion of acute coronary syndrome should comply with the protocol of management of patients with AMI while acute coronary pathology is not excluded.</p></abstract><trans-abstract xml:lang="ru"><p>Синдром такоцубо – это остро развивающаяся и, как правило, обратимая дисфункция миокарда левого желудочка. Наиболее часто синдром такоцубо проявляется локальной гипокинезией апикальных сегментов миокарда левого желудочка в ответ на эмоциональные или физические триггеры. Синдром такоцубо составляет около 2% от всех госпитализаций с подозрением на острый коронарный синдром. Диагностика синдрома такоцубо остается затруднительной. Клиническая картина острой фазы синдрома такоцубо зачастую не отличима от симптомов острого коронарного синдрома с подъемом или без подъема сегмента ST. Заболевание также сопровождается повышением маркеров повреждения миокарда, которое, однако, отличается от такового у пациентов с инфарктом миокарда с подъемом сегмента ST. Наиболее распространенными для постановки диагноза являются модифицированные критерии клиники Mayo. Патогенез заболевания также мало изучен и представлен различными теориями, в которых главную роль играют катехоламины и их воздействие на миокард. На основании описанных семейных случаев синдрома такоцубо нельзя исключить генетическую предрасположенность к развитию заболевания. Несмотря на обратимую дисфункцию миокарда, почти в половине случаев синдром такоцубо осложняется развитием острой сердечной недостаточности, а госпитальная летальность сопоставима с таковой при инфаркте миокарда с подъемом сегмента ST. Вопрос о лечении синдрома такоцубо на сегодняшний день малоизучен. Проспективных клинических исследований каких-либо препаратов не проводилось. Считается, что тактика ведения пациентов с синдромом такоцубо, госпитализированных с подозрением на острый коронарный синдром, должна соответствовать протоколу ведения больных с инфарктом миокарда, пока острая коронарная патология не исключена. На сегодняшний день заболевание требует дальнейшего изучения.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>синдром такоцубо</kwd><kwd>патогенез</kwd><kwd>прогноз</kwd><kwd>распространенность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>takotsubo syndrome</kwd><kwd>pathogenesis</kwd><kwd>prognosis</kwd><kwd>prevalence</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Y-Hassan S., De Palma R.
