1. Takotsubo cardiomyopathy

   Takotsubo cardiomyopathy or Takotsubo syndrome (TTS), also known as stress cardiomyopathy, is a type of non-ischemic cardiomyopathy in which there is a sudden temporary weakening of the muscular portion of the heart. It usually appears after a significant stressor, either physical or emotional; when caused by the latter, the condition is sometimes called broken heart syndrome. Examples of physical stressors that can cause TTS are sepsis, shock, and pheochromocytoma, and emotional stressors include bereavement, divorce, or the loss of a job. Reviews suggest that of patients diagnosed with the condition, about 70–80% recently experienced a major stressor, including 41–50% with a physical stressor and 26–30% with an emotional stressor. TTS can also appear in patients who have not experienced major stressors.The pathophysiology is not well understood, but a sudden massive surge of catecholamines such as adrenaline and norepinephrine from extreme stress or a tumor secreting these chemicals is thought to play a central role. Excess catecholamines, when released directly by nerves that stimulate cardiac muscle cells, have a toxic effect and can lead to decreased cardiac muscular function or "stunning". Further, this adrenaline surge triggers the arteries to tighten, thereby raising blood pressure and placing more stress on the heart, and may lead to spasm of the coronary arteries that supply blood to the heart muscle. This impairs the arteries from delivering adequate blood flow and oxygen to the heart muscle. Together, these events can lead to congestive heart failure and decrease the heart's output of blood with each squeeze.Takotsubo cardiomyopathy occurs worldwide. The condition is thought to be responsible for 2% of all acute coronary syndrome cases presenting to hospitals. Although TTS has generally been considered a self-limiting disease, spontaneously resolving over the course of days to weeks, contemporary observations show that "a subset of TTS patients may present with symptoms arising from its complications, e.g. heart failure, pulmonary oedema, stroke, cardiogenic shock, or cardiac arrest". This does not imply that rates of shock/death of TTS are comparable to those of acute coronary syndrome (ACS), but that patients with acute complications may co-occur with TTS. These cases of shock and death have been associated with the occurrence of TTS secondary to an inciting physical stressor such as hemorrhage, brain injury sepsis, pulmonary embolism or severe COPD.It occurs more commonly in postmenopausal women. The name "takotsubo" comes from the Japanese word takotsubo "octopus trap", because the left ventricle of the heart takes on a shape resembling an octopus trap when affected by this condition.A study published in the Journal of the American Heart Association in October 2021 found a steady annual increase in takotsubo cardiomyopathy among both women and men from 2006 to 2017, with the sharpest increases among women 50 and older.

1. 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-ischaemic cardiomyopathy in which there is a sudden temporary weakening of the myocardium. Because this weakening can be triggered by emotional stress, such as the death of a loved one, a break-up, or constant anxiety, the condition is also known as broken heart syndrome. Stress cardiomyopathy is a well-recognized cause of acute heart failure, lethal ventricular arrhythmias, and ventricular rupture.

1. Takotsubo Cardiomyopathy

   A transient left ventricular apical dysfunction or ballooning accompanied by electrocardiographic (ECG) T wave inversions. This abnormality is associated with high levels of CATECHOLAMINES, either administered or endogenously secreted from tumor or during extreme stress.
