Can anyone help me? I had a stroke in june. Upon leaving the hospital i was given an information pack on reducing the risks of strokes. However, it was information that particuarly useful to patients who had strokes due to cholestral or lifestyle. My stroke was caused by atrial fibrillation and have been prescibed warfarin. Now...I know taking omega 3 is good for cholestral but is it good for af prevention. Its questions like this and many others that I need help in answering because its so confusing(it didnt take much to confuse me before the stroke)!
