Hi This is Kaye from Manila Philippines, Is is true that after Angioplast Surgery, the patient will still feel the same symptoms? Easily get tired and might feel more weaker? My father has been diagnosed with Coronary Artery Disease, 1 vessel, Acute transient Atrial Fibrillation, Electrolyte imbalance, Hypertension; And also is it really necessary to do FFR (Fractional Flow reserve) to better determine the blockage is Angiogram procedure not enough?
