AKA transient apical ballooning syndrome or stress-induced<unk> 
Bulging out of LV apex with preserved function of the base looks like an octopus pot or "tako tsubo" in Japanese
Recent recognition of additional subtypes: reverse<unk>  (basal ballooning), mid-ventricular type, localized type
85% of cases caused by stressful event before symptoms (death of loved one, fear, argument, asthma, surgery, stroke, etc.)
Proposed mechanisms include vasospasm, microvascular dysfunction, and abnormal myocyte response to catecholamine surge
As high as 28% in ICU patients due to severe physical stress
