My echo and
EKG looked normal, blood tests were normal but an angiogram revealed a sorry state of
a left coronary artery. So when people feel something like sudden shortness of breath and chest
pains, it doesn't mean nothing has gone wrong simply because a few simple tests say so. They should take the matter seriously and
determine the exact cause. A Carotid artery needs to be pretty blocked to notice any symptoms, there is one in either side of the neck and
routes to the brain are numerous.
