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

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...

Dear Joycee 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 wit...

Dear Senthamarai 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 critic...

Dear Dyah 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...

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...
