Percutaneous coronary intervention is a common medical procedure. Serious complications don't occur often. However, they can happen no matter how careful your doctor is or how well he or she does the procedure.
Serious complications include:
Bleeding from the blood vessel where the catheters were inserted. Blood vessel damage from the catheters. An allergic reaction to the dye given during the percutaneous coronary intervention. An arrhythmia (irregular heartbeat). The need for emergency coronary bypass surgery during the procedure (2–4 percent of people). This may occur if an artery closes down instead of opening up. Damage to the kidneys caused by the dye used. Heart attack (3–5 percent of people). Stroke (less than 1 percent of people).
Sometimes chest pain can occur during percutaneous coronary intervention because the balloon briefly blocks blood supply to the heart.
As with any procedure involving the heart, complications can sometimes, though rarely, cause death. Less than 2 percent of people die during percutaneous coronary intervention.
Complications from stents include:
After percutaneous coronary intervention, the treated coronary artery can become narrowed or blocked again, often within 6 months of percutaneous coronary intervention. This is called restenosis.
Studies suggest that there's a higher risk of blood clots forming in medicine-coated stents compared to bare metal stents. However, no conclusive evidence shows that these stents increase the chances of having a heart attack or dying, if used as recommended.
The risk of complications is higher in:
People aged 75 and older People who have kidney disease or diabetes Women People who have poor pumping function in their hearts People who have extensive heart disease and blockages in their coronary (heart) arteries
