Patients with an MI (2016\u201320) were included. Exercise capacity (maximal workload in W) was assessed using bicycle ergometer testing performed before exercise-based cardiac rehabilitation, 2\u20138 weeks after hospital discharge. Outcomes were all-cause mortality and MACE (MI, stroke, and cardiovascular death), identified in national cause-of-death and patient registries (2016\u201323). Associations between exercise capacity and outcomes were evaluated using adjusted Cox proportional hazard models. The functional form of the association was assessed using restricted cubic splines. There were 15 945 patients (78% men), with a median age of 64 (IQR: 56\u201370) years, included. During a median follow-up of 3.2 (2.3\u20134.3) years, 420 deaths and 948 MACE occurred. Higher exercise capacity (per 10-W increase) was associated with an 18% lower hazard of death in men and a 33% lower hazard in women, with a linear association for both sexes. Similarly, MACE hazard decreased by 8% in men and 18% in women per 10-W increase in exercise capacity, with a curvilinear association for men and a linear association for women.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Higher exercise capacity measured by routine clinical exercise testing was associated with lower risk of all-cause mortality and recurrent MACE, with stronger associations in women.
