New Delhi: Patients with blocked coronary artery can now go for `Fractional Flow Reserve (FFR)` test to determine if a bypass surgery or angioplasty is needed or theblockage can be treated safely with medical therapy.At present, the general practice is that anyone who has a blockage of the coronary artery of over 50 percent is operated upon, according to doctors.
Blockages above 70 percent of the coronary artery are always advised for surgery to unclog it while below it is treated with medication. But the percentage of blockage on theborderline which are between 50 and 70 becomes difficult to decide and the FFR technique proves useful in taking a decision.The FFR is a guidewire-based procedure that can accurately measure blood pressure and flow through a specific part of the coronary artery. The measurement has been usefulin assessing whether or not to perform angioplasty or stenting.PTI
