FFR Limitation & Disadvantage

FFR assess of lesion severity.

FFR invasive test and allows real-time estimation of the effects of a narrowed vessel.

physical exercise or some intravenous medication is to increase the workload and oxygen demand of the heart muscle, and ischemia is detected using ECG changes or Nuclear imaging.
