For sample adults whom a doctor or other health professional had ever diagnosed as having coronary heart disease (CHEARTDIEV), CHEARTDIYR reports answers to the question, "During the past 12 months, have you had coronary heart disease?"

Coronary heart disease was not defined in the survey documentation. The Medline Plus Medical Encyclopedia defines coronary heart disease as follows: "Coronary heart disease (or coronary artery disease) is a narrowing of the small blood vessels that supply blood and oxygen to the heart (coronary arteries). Coronary disease usually results from the build-up of fatty material and plaque (atherosclerosis). As the coronary arteries narrow, the flow of blood to the heart can slow or stop. The disease can cause chest pain (stable angina), shortness of breath, heart attack, or other symptoms. Coronary heart disease (CHD) is the leading cause of death in the United States for men and women."

In 2002 and 2007, the survey identified sample adults who had other forms of heart disease during the past 12 months, including angina pectoris (ANGIPECYR), a heart attack or myocardial infarction (HEARTATYR), or any other kind of heart condition or heart disease (other than coronary heart disease, angina pectoris, or heart attack) (HEARTCONYR). Respondents for these inquiries were limited to those whom a doctor or other health professional had ever diagnosed as having the corresponding heart condition (ANGIPECEV, HEARTATTEV, and HEARTCONEV). Also in 2002, the survey identified sample adults who had congestive heart failure during the past 12 months (CONHFAILYR), again limiting the inquiry to those sample adults who had ever been diagnosed with this condition (CONHFAILEV).

The 1977 survey included a single, broad question covering all types of heart disease or heart trouble during the past 12 months. Specifically, persons age 20 and older were asked, "During the past 12 months, did you have heart disease or heart trouble?" (HEARTDISYR).
