. Aim. To evaluate the importance of exercise testing (ET) parameters and leisure time physical activity in predicting long‐term prognosis in middle‐aged women hospitalized for acute coronary syndrome (ACS). Methods and results. Women aged <66 years recently hospitalized for ACS in the Greater Stockholm area in Sweden were recruited. All underwent baseline clinical examinations including ET and then were followed up for 9 years. Nonparticipation in ET had a hazard ratio of 4.26 (95% confidence interval 2.02–8.95) for total mortality and 3.03 (1.03–8.91) for cardiovascular mortality. All ET parameters were significantly different between survivors than nonsurvivors, except for chest pain and ST‐segment depression during ET. Sedentary lifestyle and ET parameters were related to total mortality and cardiovascular mortality in a multivariate analysis adjusting for potential confounders. Predictors of total mortality were sedentary lifestyle 2.94 (1.31–6.62), exercise time 1.75 (1.07–2.87) and inadequate haemodynamic responses: low increase in pulse rate 2.04 (1.16–3.60) and systolic blood pressure (SBP) 1.88 (1.19–2.95) from rest to peak exercise. Parameters that predicted cardiovascular mortality were sedentary lifestyle 3.15 (1.13–8.74) and poor increase in SBP 2.76 (1.30–5.86) from rest to peak exercise. The relation of sedentary lifestyle to survival was substantially weakened when exercise parameters were added to the multivariate analysis model. Conclusion. In female patients <66 years surviving ACS, important independent predictors of long‐term all‐cause mortality were sedentary lifestyle, low physical fitness and inadequate pulse rate and SBP increase during exercise. Predictors of cardiovascular mortality were sedentary lifestyle and inadequate blood pressure response during exercise.
