ABSTRACT
Echocardiography is indicated:
to help determine whether a mildly raised troponin level is caused by a new cardiac event or non-cardiac illness
after myocardial infarction to determine residual LV function and to look for complications
during pain or with ST segment changes to aid the differentiation between myocardial ischaemia and other causes (e.g. pericarditis or aortic dissection)
as an emergency in cardiac decompensation to look for acute complications (papillary muscle rupture, ventricular septal rupture or free wall rupture).
