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.

Paradoxical embolisation
For a right-sided thrombus (e.g. DVT) to cause a left-sided embolism (e.g. stroke) it must obviously pass from the right-to-left side of the heart
The following cardiac lesions may cause such events
patent foramen ovale - present in around 20% of the population
atrial septal defect - a much less common cause
TOE is preferred to TTE for Dx ('coz it provides superior view of the atrial septum)
Myxoma
rare primary cardiac tumor
syncope and death due to obstruction by a "ball valve" mechanism
Use of ACE inhibitors (GISSI-3 Diabetic Subgroup Study) is associated with a 30% relative-risk reduction in the 6-week mortality rate (8.7% vs 12.4%).
