While physical activity (\n PA<\/jats:styled-content>\n ) efforts to obtain a sufficient\n PA<\/jats:styled-content>\n level are part of secondary preventive recommendations, it is still underutilized. Importantly, the effect of changes in\n PA<\/jats:styled-content>\n after\n MI<\/jats:styled-content>\n is largely unknown. Therefore, we sought to investigate the effect on survival from changes in\n PA<\/jats:styled-content>\n level, post\u2010\n MI<\/jats:styled-content>\n .\n <\/jats:p>\n <\/jats:sec>\n \n Methods and Results<\/jats:title>\n \n Data from Swedish national registries were combined, totaling 22\u00a0227 patients with\n MI<\/jats:styled-content>\n .\n PA<\/jats:styled-content>\n level was self\u2010reported at 6 to 10\u00a0weeks post\u2010\n MI<\/jats:styled-content>\n and 10 to 12\u00a0months post\u2010\n MI<\/jats:styled-content>\n . Patients were classified as constantly inactive, increased activity, reduced activity, and constantly active. Proportional hazard ratios were calculated. During 100\u00a0502\u00a0person\u2010years of follow\u2010up (mean follow\u2010up time 4.2\u00a0years), a total of 1087 deaths were recorded. Controlling for important confounders (including left ventricular function, type of\n MI<\/jats:styled-content>\n , medication, smoking, participation in cardiac rehabilitation program, quality of life, and estimated kidney function), we found lower mortality rates among constantly active (hazard ratio: 0.29, 95% confidence interval: 0.21\u20130.41), those with increased activity (0.41, 95% confidence interval: 0.31\u20130.55), and those with reduced activity (hazard ratio: 0.56, 95% confidence interval: 0.45\u20130.69) during the first year post\u2010\n MI<\/jats:styled-content>\n , compared with those being constantly inactive. Stratified analyses indicated strong effect of\n PA<\/jats:styled-content>\n level among both sexes, across age,\n MI<\/jats:styled-content>\n type, kidney function, medication, and smoking status.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n \n The present article shows that increasing the\n PA<\/jats:styled-content>\n level, compared with staying inactive the first year post\u2010\n MI<\/jats:styled-content>\n , was related to reduced mortality.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1161\/jaha.118.010108","type":"journal-article","created":{"date-parts":[[2018,12,11]],"date-time":"2018-12-11T05:00:15Z","timestamp":1544504415000},"update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":68,"title":["Increased Physical Activity Post\u2013Myocardial Infarction Is Related to Reduced Mortality: Results From the SWEDEHEART Registry"],"prefix":"10.1161","volume":"7","author":[{"given":"Orjan","family":"Ekblom","sequence":"first","affiliation":[{"name":"\u00c5strand Laboratory of Work Physiology The Swedish School of Sport and Health Sciences Stockholm Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amanda","family":"Ek","sequence":"additional","affiliation":[{"name":"\u00c5strand Laboratory of Work Physiology The Swedish School of Sport and Health Sciences Stockholm Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00c5sa","family":"Cider","sequence":"additional","affiliation":[{"name":"Department of Neuroscience and Physiology Sahlgrenska Academy & Sahlgrenska University Hospital Gothenburg Sweden"},{"name":"Department of Health and Rehabilitation\/Physiotherapy Institute of Neuroscience and Physiology University of Gothenburg and Occupational Therapy and Physiotherapy Gothenburg Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kristina","family":"Hambraeus","sequence":"additional","affiliation":[{"name":"Department of Cardiology Falun Hospital Falun Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mats","family":"B\u00f6rjesson","sequence":"additional","affiliation":[{"name":"Department of Neuroscience and Physiology Sahlgrenska Academy & Sahlgrenska University Hospital Gothenburg Sweden"},{"name":"Department of Food, Nutrition and Sport Science Center for Health and Performance University of Gothenburg Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_2_2_2","unstructured":"The National Board of Health and Welfare .
