Coronary angioplasty and stenting are minimally invasive procedures used to treat narrowed or blocked coronary arteries that supply the heart with oxygen. These techniques are applied to restore normal blood flow in patients with coronary artery disease (CAD), angina pectoris, and in emergency situations such as acute myocardial infarction.
- Angioplasty. A procedure in which narrowed arteries are widened using an inflatable balloon.
- Stenting. Placement of a special metallic scaffold (stent) to keep the artery open after angioplasty.
When are angioplasty and stenting performed?
Main indications:
- Coronary artery disease (CAD). Narrowing of the coronary arteries due to atherosclerotic plaque formation.
- Angina pectoris. Chest pain or discomfort caused by insufficient blood supply to the heart muscle.
- Acute myocardial infarction. Emergency restoration of blood flow to minimize damage to the myocardium.
- Coronary artery pathology detected during diagnostic evaluation, including stress testing, coronary angiography, or computed tomography.
Advantages of angioplasty
- Minimally invasive approach. Procedures are performed through a small vascular puncture without open surgery.
- Rapid restoration of blood flow. Relief of symptoms and prevention of severe cardiac complications.
- Short recovery period. Most patients return to normal daily activities within a few days.
- High effectiveness. Reduced risk of myocardial infarction and improved quality of life.
How is angioplasty performed in Belarus?
Coronary angioplasty and stenting in Belarus are carried out in specialized cardiology centers equipped with modern technology. The procedure begins with patient preparation, which includes preliminary examinations such as electrocardiography (ECG), stress testing, coronary angiography to assess the condition of the coronary arteries, as well as blood and urine tests. Prior to the intervention, patients are prescribed medications to prevent thrombosis, including anticoagulants and antiplatelet agents.
The angioplasty procedure is performed under local anesthesia, most commonly via the femoral or radial artery. A catheter with a balloon at its tip is introduced into the vessel and guided to the narrowed segment of the coronary artery. The balloon is then inflated, expanding the artery and compressing the atherosclerotic plaque against the vessel wall. To prevent restenosis, a stent—a metallic scaffold—is implanted to maintain the artery in an expanded state.
Several types of stents are available:
- Bare-metal stents (BMS).
- Drug-eluting stents (DES), which release medications that inhibit excessive tissue growth within the stent.
- Bioresorbable stents, which gradually dissolve over time while maintaining vessel patency.
At the end of the procedure, the catheter is removed and the puncture site is closed. The patient is transferred to a ward for observation. During the postoperative period, rest is recommended for 1–2 days, and strenuous physical activity should be avoided for 1–2 weeks. To prevent thrombosis, patients continue antiplatelet and anticoagulant therapy, as well as lipid-lowering medications. Lifestyle modifications, including a heart-healthy diet, smoking cessation, and regular moderate physical activity, are also essential.
Clinical outcomes typically include significant improvement in symptoms such as chest pain and shortness of breath, as well as a reduced risk of myocardial infarction. Drug-eluting stents can remain effective for decades when medical recommendations are carefully followed.
Coronary angioplasty and stenting in Belarus represent modern and effective approaches to the treatment of cardiovascular diseases, enabling reliable restoration of coronary blood flow and improvement in patient quality of life. These procedures are safe, require minimal recovery time, and substantially reduce the risk of myocardial infarction and other serious complications. Regular medical follow-up and adherence to a healthy lifestyle help maintain long-term cardiac health.
