FFR in 2024: Current Status in PCI Management

WebFractional flow reserve, also known as FFR, is a measurement of how well blood can flow through the coronary arteries. These arteries bring oxygen-rich blood to the heart to be pumped throughout the rest of the body. Narrowing or blockages in these arteries is called coronary artery disease. This can lead to a heart attack without treatment. Your provider uses an instrument to take blood pressure readings on both sides of a blockage inside your coronary artery. The equipment uses these readings to calculate your fractional flow reserve.
