I have been reading up on apical hypertrophic cardiomyopathy (AHCM) and understand that it is genetic and there is a 50% chance of it being passed on to children. Anyone diagnosed with AHCM is told to advise their siblings to get themselves tested. Now, imagine that the one sibling is an airline pilot with a Class 1 medical who has no symptoms whatsoever. The Class 1 would have required a regular ECG which also will have not shown any problems. The ECG is the first test for AHCM but this is normally followed up with an ultrasound.
Having invested a lot of money in a career which is going along very successfully, it is very tempting not to tell the sibling pilot, or, if he is told, he must be tempted to keep the very small risk of developing serious symptoms to himself.
In this case does anybody know if the ECG and lack of any symptoms is a justifiable reason for not taking this any further.
