To the Editor: Dr Mora and colleagues1 found that both exercise capacity and heart rate
recovery after exercise were related to risk of cardiovascular and all-cause
mortality. They concluded that their "findings support the potential use of
exercise testing as a risk-stratification tool for primary prevention in asymptomatic
women. . . ." Although the authors controlled for several cardiac risk factors,
they did not include current level of exercise in their analysis. It is possible
that simply asking women whether they regularly engage in strenuous exercise
or hard physical labor would also similarly identify those women at increased
risk of cardiovascular death.
