The reality is that the number of heart attacks is plummeting in the western world. An ECG plus an exercise ECG at 60 is pure screening and we could add cardiac CT and other tests but there is the issue of cost vs return as well as the conundrum of what to do with an abnormal result in an asymptomatic pilot.....
Statins do reduce the incidence of sudden death which is why many doctors take them. However the main risk factors are smoking, diet, obesity, family history, exercise and hypertension. Hopefully this is common knowledge amongst professional pilots with an interest in preserving their medicals.
So RIP Douglas Davis but no need for the rest of us to panic.
