I assume 160/95 is the threshold to get flying again?
JAR regulations actually specify 160/90, but this is more than just a numbers game.
Once BP is found to be raised, the question has to be asked : "
is there any other increased risk of incapacitation from cardio-vascular causes ?" So, as well as treating and recording the BP, the AME will want to assess other things such as family history, blood tests (lipids & electrolytes), exercise ECG, echocardiograph (especially if any murmurs heard).
Once all that is deemed satisfactory, then a return to flying status can be considered.
