HAKBREATH reports responses to a question about whether "[s]hortness of breath" is a symptom "that someone may be having a heart attack." Interviewers read a list of symptoms and asked respondents to answer "yes" or "no" to whether each was a symptom of a heart attack. These symptoms included (besides HAKBREATH):

  • Pain or discomfort in the jaw, neck, or back (HAKJAW)
  • Feeling weak, lightheaded or faint (HAKWEAK)
  • Pain or discomfort in the arms or shoulder (HAKARM)

The Mayo Clinic website mentions all of the symptoms listed above as "typical heart attack symptoms."

A related heart attack knowledge variable includes HAKBEST (Best thing to do for person having a heart attack).
