In this study, a submaximal exercise parameter, oxygen uptake efficiency slope (OUES), was used to monitor the benefit of early mobilization within 48\u2009h after AMI. An early mobilization protocol within 48\u2009h after AMI has been initiated since 1 September 2012 in our center. Patients with onset time of AMI within 1 year before and 1 year after initiation of the early mobilization protocol were recruited for comparisons. Sixty patients were analyzed on the basis of this criterion, and were subjected to predischarge submaximal exercise tests. The OUES calculated with 100% exercise duration (OUES<jats:sub>100<\/jats:sub>) and calculated with the first 50% of exercise duration (OUES<jats:sub>50<\/jats:sub>) were obtained and analyzed. Both OUES<jats:sub>100<\/jats:sub> and OUES<jats:sub>50<\/jats:sub> of the AMI patients with early mobilization were significantly higher than those without early mobilization (<jats:italic toggle=\"yes\">P<\/jats:italic>=0.025 and 0.007, respectively). The OUES<jats:sub>100<\/jats:sub> and OUES<jats:sub>50<\/jats:sub> were also highly correlated (<jats:italic toggle=\"yes\">r<\/jats:italic>=0.891, <jats:italic toggle=\"yes\">P<\/jats:italic>&lt;0.001). The subgroup analysis using patients within 3 months before and 3 months after initiation of the protocol also showed a significant difference. OUES could be used to measure the exercise capacity and monitor the effect of phase I cardiac rehabilitation in patients soon after AMI. Early mobilization within 48\u2009h following AMI significantly enhanced the patient\u2019s exercise capacity.<\/jats:p>","DOI":"10.1097\/mrr.0000000000000229","type":"journal-article","created":{"date-parts":[[2017,4,13]],"date-time":"2017-04-13T20:29:43Z","timestamp":1492115383000},"page":"215-219","source":"Crossref","is-referenced-by-count":8,"title":["Improved
