National trends in the prevalence and medical history of angina: 1988 to 2012.

ABSTRACT:

Background

The prevalence of angina from 1971 to 1994 was relatively flat for whites and blacks. We ask whether the prevalence and medical history of angina have changed during 1988 to 2012.

Methods and results

We used the National Health and Nutrition Examination Survey data from 1988 to 2004 and the data from the six 2-year surveys from 2001 to 2012. We calculated trends in both crude and standardized prevalence rates for the Rose questionnaire on angina (symptomatology) and a question asking whether the respondent had ever been told by a medical professional that they had angina (medical history). In 2009 to 2012, there were on average 3.4 million (95% confidence interval, 2.8-4.0 million) people aged ≥40 years in the United States each year with angina (Rose questionnair
