This means that blockages in the arteries of the heart might be giving your mom that choking
sensation. With current evidence, it may be reasonable to obtain a stress echocardiogram
or nuclear study to see how big or small is the area of ischemia; if it is relatively small, then heart medications are very effective at controlling symptoms and improving outcomes; if the area is actually big, then an angiography
of the heart could be indicated (look at the vessels of the heart with dye for blockages)..
