What are the risks of heart stents?

What are the risks associated with heart angioplasty and stent placement?

• an allergic reaction to medication or dye.
• breathing problems.
• bleeding.
• a blockage of the stented artery.
• a blood clot.
• a heart attack.
• an infection.
• re-narrowing of the artery.

Is stent surgery high risk?

Conclusions: Despite a high-risk clinical and angiographic profile, coronary stenting can be safely performed in octogenarians with a high procedural success rate, low complication rate, and excellent 12-month outcome.

What can go wrong with a stent?

A stent can cause blood clotting, which may increase the risk of heart attack or stroke. The National Heart, Lung, and Blood Institute state that about 1 to 2 percent of people who have stented arteries develop a blood clot at the site of the stent. Doctors will usually prescribe one or more drugs to prevent clotting.

Do heart stents fail?

Stents have revolutionized percutaneous coronary interventions (PCI), impacting on both acute and long-term results. However, despite improvements in stent design, stent deployment failure is not an unusual event.

How long do you need to be on blood thinners after a stent?

It has been common practice for patients who have had a stent placed to clear a blocked artery to take an anti-clotting drug (such as Plavix, Effient, or Brilinta) plus aspirin for 12 months after the procedure. Taking these two medications, called dual anti-platelet therapy, reduces the risk of forming blood clots.

What is the failure rate of stents?

A total of 175 (3.3%) stents in 151 (4.3%) patients failed. Failure to deliver the stent to the lesion site was the main cause in 139 patients (92%) and failure either to expand adequately the stent or premature disengagement of the stent from the balloon in only 12 patients (8%).

What is the average life of a stent?

What is the typical lifespan of a stent? Stents are small tubes inserted into your body to reopen a narrowed artery. They are made to be permanent — once a stent is placed, it’s there to stay. In cases when a stented coronary artery does re-narrow, it usually happens within 1 to 6 months after placement.
