Codes and Frequencies
CHEARTDIEV identifies sample adults whom a doctor or other health professional ever diagnosed as having coronary heart disease. In 2002 and 2007, individuals who acknowledged ever being diagnosed with coronary heart disease were asked the follow-up question, "During the past 12 months, have you had coronary heart disease?" (CHEARTDIYR).
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 1997 and subsequent years, the survey collected information from sample adults about a number of other conditions related to coronary heart disease. In 1997 forward, sample adults were asked whether they were ever told by a doctor or other health professional that they had angina pectoris (ANGIPECEV). Sample adults were also consistently asked whether they had ever been diagnosed with a heart attack or myocardial infarction (HEARTATTEV) or any other heart condition or heart disease (other than heart attack, angina pectoris, and coronary heart disease) (HEARTCONEV). In 2002 and 2007, follow-up questions for those giving affirmative answers covered whether sample adults had a heart attack (HEARTATYR), angina pectoris (ANGIPECYR), or any other heart condition or heart disease (HEARTCONYR) during the past 12 months. The 1999 survey collected information on age when first diagnosed with a heart attack (HEARTATAGE).
In 1999 and 2002, the survey collected information on whether sample adults were ever diagnosed with congestive heart failure (CONHFAILEV) and, in 2002, about whether they had congestive heart failure during the past 12 months (CONHFAILYR).
The 1977 survey included a single, broad question covering all types of heart disease or heart trouble. Specifically, persons age 20 and older were asked, "During the past 12 months, did you have heart disease or heart trouble?" (HEARTDISYR).
For sample children, from 1997 forward, information was collected on whether the child was ever diagnosed with congenital heart disease (CONGHARTEV) or with some other (non-congenital) heart condition (NONCONHARTEV).
Other than changes to the universe and the questionnaire redesign introduced in 2019, this variable is comparable over time. The NHIS questionnaire was substantially redesigned in 2019 to introduce a different data collection structure and new content. For more information on changes in terminology, universes, and data collection methods beginning in 2019, please see the user note.
