Overview
Percutaneous Coronary Intervention (PCI) is a minimally invasive procedure used to open narrowed or blocked coronary arteries and improve blood flow to the heart muscle. It is commonly performed using balloon angioplasty, often followed by placement of a coronary stent to help keep the artery open.
PCI may be recommended for patients with significant coronary artery narrowing, persistent symptoms despite medical treatment, or certain types of acute coronary syndrome. It can also be performed as an emergency procedure during an eligible heart attack to restore blood flow to the affected heart muscle.
At Sarvodaya Hospital, the decision to perform PCI treatment is based on the patient's symptoms, clinical condition, angiography findings and overall cardiovascular risk. The cardiology team determines whether angioplasty and stenting or another form of coronary artery blockage treatment is most appropriate.
When Is PCI Recommended?
PCI may be recommended when a coronary artery is significantly narrowed or blocked and restoring blood flow is expected to improve the patient's condition.
It may be considered for significant coronary artery blockage causing symptoms, angina that is not adequately controlled with medicines, acute coronary syndrome, certain types of heart attack, a blocked or severely narrowed artery identified during coronary angiography, reduced blood flow to an important area of the heart, or in selected patients who require revascularisation based on their coronary anatomy and clinical condition.
The decision depends on factors such as the number and location of blockages, severity of narrowing, symptoms, heart function and overall health.
How Is PCI Performed?
During PCI, a thin catheter is guided through a blood vessel to the coronary arteries, where contrast dye and imaging identify the location and severity of the blockage. A small balloon may then be inflated at the narrowed section to widen the artery, and a coronary stent may be placed to help maintain blood flow.
The procedure generally involves gaining vascular access through an artery in the wrist or groin, performing coronary angiography, carefully passing a guidewire across the affected area, performing balloon angioplasty when required, placing a stent when indicated, assessing blood flow after the intervention, and removing the catheter while appropriately managing the access site. Not every patient requires the same technique, and the approach depends on the location and characteristics of the coronary blockage.
PCI for Heart Attack
PCI can be an emergency treatment for eligible patients experiencing certain types of heart attack, particularly when a coronary artery is acutely blocked.
Emergency PCI for heart attack aims to restore blood flow as quickly as possible and limit damage to the heart muscle. The patient first undergoes urgent clinical assessment and appropriate investigations, including an ECG and other tests. Coronary angiography may then identify the blocked artery, allowing PCI to be performed when indicated.
Because heart attacks are medical emergencies, patients with symptoms such as sudden chest pressure or pain, breathlessness, sweating, nausea or unexplained discomfort should seek emergency medical care immediately.
PCI Technology and Infrastructure
PCI relies on specialised cardiac imaging and catheterisation technology to guide the procedure and assess the coronary arteries.
Depending on the patient's clinical requirements, PCI may involve a cardiac catheterisation laboratory for coronary angiography and catheter-based interventions, fluoroscopy and X-ray imaging to provide real-time guidance for catheters, wires and other devices, and coronary angiography to identify the location and severity of coronary artery blockages.
Balloon catheters may be used to widen narrowed sections of the coronary arteries, while coronary stents can support the treated artery and help maintain blood flow.
Continuous cardiac monitoring helps the clinical team assess heart rhythm and vital signs throughout the procedure, while contrast imaging helps visualise blood flow and coronary artery anatomy.
Benefits of PCI
- Restores Blood Flow: PCI can improve blood flow through a significantly narrowed or blocked coronary artery.
- Minimally Invasive: The procedure is performed through a small vascular access point rather than open-heart surgery.
- Rapid Treatment During Heart Attack: Emergency PCI can restore blood flow in suitable patients with an acute coronary artery blockage.
- Relieves Symptoms: Successful treatment may reduce angina and improve exercise tolerance.
- Supports Heart Function: Timely restoration of blood flow during an appropriate heart attack can help limit damage to the heart muscle.
- Shorter Recovery Than Open Surgery: Recovery after uncomplicated PCI is generally shorter than recovery after coronary bypass surgery.
PCI Recovery
Recovery after PCI depends on the complexity of the procedure, the access site, the number of arteries treated and the patient's overall health.
After the procedure, the medical team monitors the patient for changes in heart rhythm, blood pressure and the vascular access site. Some patients may be discharged relatively soon after an uncomplicated procedure, while others may require longer observation or hospitalisation.
Post-Treatment Lifestyle Modifications
- Take Medicines as Prescribed: Continue antiplatelet medicines and other prescribed cardiac medicines exactly as directed by your cardiologist.
- Care for the Access Site: Follow the medical team's instructions for caring for the wrist or groin access site after the procedure.
- Resume Activities Gradually: Avoid strenuous activities initially and gradually return to normal activities according to your cardiologist's advice.
- Attend Follow-Up Appointments: Keep all scheduled cardiac follow-ups so your recovery and heart health can be monitored.
- Follow Heart-Healthy Habits: Maintain a balanced diet, stay physically active as advised and avoid tobacco.
- Participate in Cardiac Rehabilitation: Join a cardiac rehabilitation programme when recommended to support recovery and improve cardiovascular health.
- Recognise Warning Signs: Seek immediate medical attention for severe chest pain, significant bleeding, severe breathlessness or other concerning symptoms.
