Heart stent

Yes, those with diabetes have a two to fourfold risk of developing Coronary Artery Disease (CAD) and the extent and severity of CAD depends on the duration of diabetes. Whether the extent of coronary disease will warrant a stent or other treatment depends on the results of the cor...

NO – heart stents cannot be removed for any reason except in the extremely case of a stent getting infected (about 17 or so cases reported since 1986 when the first stent was implanted and of course millions of people have had stents since then). In which case heart surge...

I am afraid the evidence does point to the fact that there is a clear advantage both in terms of quality of life and mortality benefit (for instance in those patients who have a narrowing of more than 50% in the left main stem ie the major branch on the left side of the heart, only ...

You need not worry about this aspect at all. When I do the procedure I always ensure there is adequate pain relief (they are big on pain relief in the UK and the cath lab sister would always be watching the patient intently and if the patient were to wince ever so slightly th...

A heart stent should and will last for life. A stent after all, is a wire-mesh scaffold and functions as such. Once a stent has been placed the inner vessel wall (called endothelium) slowly grows over it until it “heals”. Drug-coated stents ensure that this healing is...

There is no one ‘best heart stent” in Singapore or elsewhere. There are many different stents available right from bare metal stents (used seldom nowadays) to Drug-coated stents (third and fourth generation) to absorbable stents (more recent entrants) However diffe...

Contrary to what you may have heard the number of stents should be determined only by the degree and extent of any narrowing and also how the procedure unfolds. Most cardiologists do not know the coronary anatomy before the procedure unless an angiogram has been done prior. While...
