borg, Sweden.
As the first phase of a longitudinal population
study of women, a cross-sectional study of altogether
1462 women aged 38-60 was carried out in 1968-1969 in
Göteborg, Sweden. The women have then been re-studied
in 1974-1975 and 1980-1981. In addition, all women of
the same age in Göteborg with myocardial infarction
during the years of 1968-1970 were examined.
A history of angina pectoris was initially reported
by 29 women, 28 of whom have been followed-up for 12
years. Among these women, 4 have died, 2 from myocar-
dial infarction and another woman has survived a myo-
cardial infarct during the period. ECG changes at
rest indicating ischaemic heart disease (IHD) was
observed in 23 women, 22 of whom have been followed-
up for 12 years. Five of these women have died, 3 of
whom from myocardial infarction, and another woman
has survived a myocardial infarct. In a respresenta-
tive subsample comprising 194 women, a maximal work
performance test was carried out. ECG changes indi-
cating IHD (Minnesota Code 4:1-2 4 min after maximal
wcrk) was observed in 30 of these women, 29 of whom
have been followed-up for 12 years. Five of these
women have died, one from myocardial infarction,
while none of the other 29 women has suffered from
myocardial infarction.
It seemed that the prognosis of women with history
of angina pectoris or ECG changes at rest or exercise
indicating IHD was moderately different from that of
other women in the population.
