ASK DR NANDAKUMAR: HEART STENTS

Dr Nandakumar Ramasami
Cardiologist
Singapore
Consult Doctor
FOLLOW
Dr Nandakumar Ramasami
Cardiologist
Singapore

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

Can heart stents be removed for any reasons?

What are the chances of being completely angina-free after having a successful angioplasty?

What is the best heart stent in Singapore for blocked coronary arteries?

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...

How do cardiologists determine how many heart stents are necessary?

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...

How accurate is a CT coronary angiogram versus a cardiac MRI or “traditional” angiogram?

Why do doctors not perform angioplasties for minor blocked heart vessels?
