Coronary artery disease is a disease caused by the accumulation of "fat" (cholesterol) that creates plaque that narrows or blocks one or more arteries. Complete blockage of a coronary artery will lead to a heart attack. At this time, angioplasty and coronary stenting will help treat stenosis or obstruction.

1. What are the indications for coronary angioplasty and stenting?

Catheter coronary intervention is a method of using a small catheter (catheter) to go inside the blood vessel to the coronary artery of the heart, thread the wire along this catheter through the lesion, and then put a balloon or stent up to dilate it. The narrow, blocked area of ​​the artery helps to open the artery, and finally, a stent is placed to circulate the artery. Besides coronary intervention, it is also possible to perform other special procedures at the same time, such as aspiration thrombosis, drilling to break up atheroma.
Accordingly, cases with indications for coronary angioplasty and coronary stenting include:
Patients with stable but uncontrolled angina despite optimal medical treatment Stable angina evidence of myocardial ischemia and damage to the coronary artery that supplies large areas of myocardium Unstable angina , acute myocardial infarction without ST-segment elevation that stratifies the cardiovascular risk of high patient ST-segment elevation acute myocardial infarction Patients with symptoms of coronary re-stenosis or stent occlusion after percutaneous coronary intervention MORE: Learn about coronary artery angiography, dilation and stenting at Vinmec

2. Contraindications of coronary artery angioplasty and stenting

In addition to the cases prescribed by the doctor to dilate and place coronary artery stents, the following cases will be contraindicated with this technique:
Patients with severe, diffuse lesions; multiple coronary artery lesions; distal lesion unsuitable for intervention Coronary artery injury has a high risk of death if that coronary artery is likely to be re-occluded during intervention Patients with predisposition to heavy bleeding (platelet low, blood clotting disorders ) Patients do not adhere to treatment before and after the intervention procedure Patients with multiple re-stenosis after the intervention Although it is a new intervention method, it offers many treatment opportunities, but When performing coronary artery angioplasty and stenting procedures, patients may experience some complications such as: bruising and bleeding at the needle puncture site, coronary artery narrowing and re-obstruction right after successful intervention, occlusion. pulse in the arm after a radial (below wrist) procedure. In addition, patients may also have prolonged arrhythmias, myocardial infarction.
There are also some very rare complications (less than 1%) such as:
Sudden blockage of the stent within the first month causing angina or myocardial infarction Allergic reaction to contrast Reaction to anticoagulants Renal dysfunction as a side effect of the contrast agent Stroke Vascular rupture Hemopericardium.
