Abstract

OBJECTIVE:

To examine temporal trends in the prevalence of nonfatal coronary heart disease in the United States.

DESIGN:

Four national cross-sectional health surveys: National Health and Nutrition Examination Survey (NHANES) I (1971-1975), NHANES II (1976-1980), NHANES III (1988-1994), and Hispanic HANES (HHANES) (1982-1984).

SETTING:

United States.

PARTICIPANTS:

Persons aged 40-74 years.

MAIN OUTCOME MEASUREMENTS:

Prevalence of angina, self-reported myocardial infarction, and electrocardiographically defined myocardial infarction (ECG-MI).

RESULTS:

Generally, the age-adjusted prevalence of angina pectoris was higher among women than men, but the reverse was true for self-reported myocardial infarction and ECG-MI. Increases in the prevalence of angina pectoris occurred for Mexican-American men and women, and African-American women, but were not statistically significant for the latter. Age-adjusted rates of self-reported myocardial infarction increased among African-American men (P=.019) and women (P=.005) and Mexican-American men (P>.05), but decreased among White men (P>.05) and women (P>.05). The prevalence of age-adjusted ECG-MI decreased among African-American men and women, White women, and to a lesser degree, White men; however, none of these decreases were statistically significant. Relative standard errors for ECG-MI prevalence in NHANES I and II among African Americans were large; therefore, prevalence trends need to be interpreted cautiously.

CONCLUSIONS:

The decreases in ECG-MI could be due either to decreased incidence of coronary heart disease or myocardial infarction, or increases in the rates of timely cardiac interventions that minimize damage to the myocardium.
