Percutaneous Coronary Intervention (PCI)

Coronary artery disease (CAD) is one of the commonest causes of death in Singapore. It can affect patients in the form of heart attacks (also known as ‘myocardial infarction’) or stable chest pain syndromes (‘stable angina’). While suitable patients with stable angina can be treated with medicines, patients with heart attack need emergency treatment.

NHCS offers 24-hour coronary angioplasty services, also known as percutaneous coronary intervention (PCI), to treat patients with heart attacks. In PCI, a special catheter is inserted into the heart (coronary) artery. This allows a very fine wire to be inserted in the artery. A balloon can then be advanced into the artery across the blockage. The balloon is inflated once it has been placed into the narrowed area of the coronary artery. The inflation of the balloon compresses the blockage in the artery and makes a larger opening inside the artery. A stent (wire mesh tube) is then placed across the blockage to keep the artery open. It restores blood flow through the coronary arteries, thereby relieving symptoms and improving heart function.

With a strong team of highly experienced and well-trained interventional cardiologists, NHCS performed 2014 coronary angioplasty and stenting procedures in 2024. The mean mortality rate for elective PCI at NHCS was 0.32% from 2020 to 2024.

PCI Mortality:

• 30-Day Mortality: Death occurs within 30 days of elective PCI procedure performed.
