compared with inotropic agents, to prevent the development of significant intraventricular gradients and subsequent hemodynamic deterioration. A word of caution should be added—in patients with cardiogenic shock associated with LVOTO, inotropic agents, vasodilators, and diuretic agents, as well as intraaortic balloon counterpulsation may lead to worsening of shock and worse outcomes (4–6). Ball...

Tako-Tsubo cardiomyopathy (TC) is a syndrome of clinical presentation, electrical impulses, and segmental impairments similar to the anterior myocardial infarction and it is characterized by the absence of significant coronary diseases causing ventricular dysfunction and by the normalization of the left ventricular function in the short term. We present the case of a 61-year-old woman, with hig...

Transient left ventricular dysfunction syndrome (TLVDS), or Tako-Tsubo cardiomyopathy (TC), is a clinical entity in which patients present with features of acute coronary syndrome, electrocardiogram abnormalities, and transient left ventricular (apical or mid-ventricular) dysfunction. Patients usually recover from this condition four to six weeks after the event. The etiology or triggering fact...

To the Editor, Stress-induced cardiomyopathy (SIC) (also known as ampulla cardiomyopathy, tako-tsubo syndrome, and broken heart syndrome) mimicking an acute myocardial infarction is a unique acute cardiac syndrome that appears under physically or emotionally stressful circumstances. It was first described in Japan and is typically characterized by chest pain, elevated ST-segment on electrocardi...
