The reliability of the STENTS depends on how well you take your medicines after stenting, how well you take the advised precautions, no smoking ( if you do ), adapting healthy lifestyle habits life daily morning walks, no junk or fried food, healthy diet, weight control and how your body respond to stent.2.
