The logic of stenting obstructed coronary arteries is simple. A stent unblocks the artery. Subscribe now Stenting stable coronary artery disease has not been convincingly proven to reduce the risk of future heart attacks or death 1. But coronary stenting is not the only way to reduce symptoms of angina. All is fixed.

One of the most common questions I get is, “ Do I need a stent to treat my heart disease?” ” Typically, several of this person’s friends have had stents, so it seems natural to ask. First, we must understand what a stent is and why it is used. The stent ‘unblocks’ it. Flow is restored.
