Change in the prevalence of coronary heart disease among Finnish elderly men and women in the 1990s.
OBJECTIVE
To characterise the prevalence of, and changes in, coronary heart disease (CHD) among men and women aged between 64 and 71 years in the 1990s.


METHODS
A study of clinical epidemiology involving two cohorts of elderly persons in 1990-1991 and 1998-1999.


METHODS
Primary health care in the municipality of Lieto in southwestern Finland.


METHODS
Persons between 64 and 71 years of age in the southwest of Finland in 1990-1991 and 1998-1999.


METHODS
The occurrences of CHD were estimated using the history of a previous myocardial infarction or coronary revascularisation procedure evident in the medical records and with ischaemia or infarction as established on ECG according to the Whitehall criteria.


RESULTS
The prevalence of 'probable' CHD decreased among men and women aged between 64 and 71 years, whereas the prevalence of 'possible' CHD decreased among women alone. Silent myocardial infarctions were common among women of both cohorts. Many more men of the second cohort, compared to the first one, had undergone a coronary angioplasty or bypass operation.


CONCLUSIONS
The prevalence of CHD decreased among elderly women more clearly than among young elderly men. The favourable development illustrating a decrease in the prevalence of CHD among women should be sustained, while health promotion activities will need to be directed more actively towards men.
