Only One-Third of Adults Know Heart Attack Signs

Only about one-third of U.S. adults are aware of the five major warning signs of heart attacks, according to a CDC survey in MMWR.

The telephone survey of 72,000 people, conducted in 2005, found that, nationally:


48% recognize pain or discomfort in the jaw, neck, or back as a warning sign;
62%, feeling weak, lightheaded, or faint;
85%, pain or discomfort in the arms or shoulder;
92%, chest pain or discomfort;
93%, shortness of breath.

The numbers were even lower among non-Hispanic blacks and Hispanics, men, and those with less than a high school education.
