The adjusted risk of cardiovascular death was evaluated by landmark analysis starting at the time of the MI through 180 days after the event. Patients who experienced an MI during follow-up had a higher risk of cardiovascular death at 6 months than patients without an MI (6.5% versus 1.3%,\n              <jats:italic>P<\/jats:italic>\n              &lt;0.001).

After adjustment for important clinical covariates, the occurrence of any MI was associated with a 5-fold higher risk of death at 6 months (95% confidence interval 3.8\u20137.1), with similarly increased risk across subtypes.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions\u2014<\/jats:title>\n            <jats:p>MI is associated with a significantly increased risk of cardiovascular death, with a consistent relationship across all types as defined by the universal classification system.
