EARLY HEART DISEASE

ANCHOR LEAD: AN INTERNATIONAL TEAM IS LOOKING AT THE BEST WAY TO ASSESS CORONARY ARTERY DISEASE, ELIZABETH TRACEY REPORTS

Atherosclerosis is the process of plaque development on the inside of arteries that can give rise to heart attacks, strokes and other critical health problems, but surprisingly, sometimes such plaques may be present but aren’t limiting blood supply.  Now an international study led by Joao Lima and others at Johns Hopkins is using two different imaging techniques to assess whether blood supply, or perfusion, is compromised in the heart.

LIMA: There is mounting evidence that the benefits of revascularization are much greater when they are done for lesions that are also limiting blood perfusion so we would hope that by creating this method we will guide the interventional procedures to be more effective and therefore benefit patients more in the long run because of their greater effectiveness.         :28

Restoring the blood flow, or revascularization, should likely be done only when a perfusion problem exists.  At Johns Hopkins, I’m Elizabeth Tracey.
