A simple neck scan could detect men at high risk of heart failure

> However, the carotid arteries may be a red flag for heart failure also. This is because, when the carotid arteries become less flexible, they do not expand properly to let blood through. This can raise blood pressure, which forces the heart muscle to work harder. Over time, this can lead to heart failure.

SO - why can't a simple blood pressure measurement screen for that "become less flexible" issue? Without needing any fancier equipment, higher-skill personnel, or longer test?

Because high blood pressure can have many transient causes: caffeine, exercise, stress, dehydration, even high salt intake. Further, other diseases can also cause high blood pressure, such as diabetes, and Hypertension (high blood pressure) is also it's own disease.

Unless non-high blood pressure is rare, this looks like optimal code

   bp = TakeBloodPressure()
   IF( NotHigh( bp ) )
      THEN
         DONE
      ELSE
         InvestigateCause( bp )
