Codes and Frequencies
ANGIPECEV identifies adults whom a doctor or other health professional ever diagnosed as having angina or angina pectoris. Refer to the Comparability and Universe tabs for complete information on the universe.
Angina pectoris, which was not defined in the survey documentation, consists of sudden attacks of constricting pressure or pain, often in the chest, resulting from not enough blood and oxygen getting to the heart muscle.
In the 2002 and 2007 surveys, persons who acknowledged ever being diagnosed with angina were asked the follow-up question, "During the past 12 months, have you had angina pectoris?" (ANGIPECYR).
Angina is generally caused by 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 coronary heart disease (CHEARTDIEV). 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), coronary heart disease (CHEARTDIYR), 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).
Changes in universe limit the comparability of this variable in 1984 and 1989 to other years. In 1984, this question was asked of sample persons ages 55 and older. In 1989, this question was included in the Diabetes supplement and asked only of persons ages 18 and older who also had confirmed diabetes.
In all other years, this question was asked of sample persons ages 18 and older.
Questionnaire design changes introduced in 2019 limit comparability with earlier years. 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.
