looking at the person in front of you ,is there a valve or an artery in the back of the heart just as you are facing a person in front of you ?
if a person already has two stents in two different veins and still does not feel good ,very tired, sleepy,and does not have the pep or strengths the person had before the stents and still has chest pains,sometimes strong ,sometimes
weak,this person has had all kinds of test and passed them all,by a cardiologist.
