SB, light\u2010intensity PA, and moderate\u2010vigorous intensity PA were objectively assessed for 24\u2009h\/d during hospitalization and up to 7\u2009days after discharge in 165 patients. Changes in PA and SB from the hospital to home phase were evaluated using mixed\u2010model analyses, and outcomes were stratified for predefined subgroups based on patient characteristics. Patients (78% men) were aged 65\u00b110\u2009years and diagnosed with ST\u2010segment\u2013elevation MI (50%) or non\u2013ST\u2010segment\u2013elevation MI (50%). Sedentary time was high during hospitalization (12.6 [95% CI, 11.8\u201313.7] h\/d) but substantially decreased following transition to the home environment (\u22121.8 [95% CI, \u22122.4 to \u22121.3] h\/d). Furthermore, the number of prolonged sedentary bouts (\u226560\u2009minutes) decreased between hospital and home (\u22121.6 [95% CI, \u22122.0 to \u22121.2] bouts\/day). Light\u2010intensity PA (1.1 [95% CI, 0.8\u20131.6] h\/d) and moderate\u2010vigorous intensity PA (0.2 [95% CI, 0.1\u20130.3] h\/d) were low during hospitalization but significantly increased following transition to the home environment (light\u2010intensity PA: 1.8 [95% CI, 1.4\u20132.3] h\/d; moderate\u2010vigorous intensity PA: 0.4 [95% CI, 0.3\u20130.5] h\/d; both\n                      <jats:italic>P<\/jats:italic>\n                      &lt;0.001).
