Ask Dr Nandakumar: Heart Stents
Ask Dr Nandakumar: Heart Stents

Coronary heart disease is the most common type of heart disease in many developed countries. It happens when you have fatty substance that builds up in your artery. That reduces blood flow and thus oxygen supply to the heart muscle. Heart stents are used to 'unclog' the artery and restore the blood flow. 

Learn about how heart stents are used to treat coronary heart disease as Dr Nandakumar answered questions from readers on: 

  • Best treatment for blocked heart vessels
  • What happens during an angioplasty 
  • Risks and complications associated with stent placement
  • What happens after an angioplasty

Well done indeed! Stopping smoking is the best gift you have given yourself and your family this New Year! You probably feel a better sense of smell and taste. By now more oxygen is reaching your heart and muscles easily and your immune function and circulation are getting better. ...

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...

Let me give you a very brief overview of the development in the history of stents before coming to the practical aspects. In the 1960’s Dr Dotter described the conceptual aspect of angioplasty ie using a device like a catheter to dilate a narrowed artery. Dr Andreas Gruntzi...

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...

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 ...

Yes, 100% blocked arteries can be treated and many techniques exist nowadays. If the artery can be opened up through the normal route of blood flow it is called “antegrade” technique and there are newer specialized kits available for this technique. There are also...

Recovery time after an angioplasty is pretty similar in most parts of the globe. In terms of recovery we generally aim for a 4 to 6 week period to get back to full activity. Usually the cardiac rehabilitation team will come to meet you if you have been admitted with a heart att...

I would say the chances of being completely angina free depends on the extent of the disease ie if you have diffuse multiple blockages or one or two critical blockages. With diffuse extensive disease, while you may improve the prognosis by treating the critical large vessels, ...

The coronary angiogram is the current gold standard to establish the degree of coronary artery disease and with experience one can usually determine the stenosis with just “eyeballing”. However, I do use adjunct imaging inside the blood vessel itself, and this helps...

Yes we do use devices occasionally to remove/shave/excise plaques but this is used in less than 5% of coronary angioplasties at present. The current devices licensed for plaque removal usage in the heart are called: Rotablator (a nickel plated brass burr with microscopic di...
