However, there is little research on this topic, especially in health care settings with limited resources. This study aims to detect changes in QoL and its associated factors among patients with unstable angina after percutaneous coronary intervention.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A longitudinal design was conducted with two repeated rounds of measurements, 1 and 3 months after intervention, using the generic SF\u201036 questionnaire, in 120 patients from Vietnam National Heart Institute. A linear mixed\u2010effects model was used to assess changes in patient QoL over time while adjusting for other covariates.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Only two out of eight QoL subscales (social functioning and emotional well\u2010being) declined after 1 month, but these tended to rise again after 3 months, while scores of all other QoL subscales increased. Adjusting for covariates, QoL increased slightly after 1 month of intervention (<jats:italic>\u03b2<\/jats:italic> = 0.65, 95%CI = \u22120.86 to 2.16) but improved by almost six QoL points after 3 months (<jats:italic>\u03b2<\/jats:italic> = 5.99, 95%CI = 4.48 to 7.50). Four confounders significantly associated with a decline in QoL were older age, being retired, living in rural areas, and having abnormal troponin level.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>QoL of the patients with unstable angina improves significantly 3 months after intervention, rather than after 1 month. More attention should be given to patients, who are old, retired, live in rural areas and have abnormal troponin level.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jep.13416","type":"journal-article","created":{"date-parts":[[2020,6,16]],"date-time":"2020-06-16T09:06:03Z","timestamp":1592298363000},"page":"325-332","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Changes in, and predictors of, quality of life among patients with unstable angina after percutaneous coronary intervention"],"prefix":"10.1111","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5896-9661","authenticated-orcid":false,"given":"Huy","family":"Van Nguyen","sequence":"first","affiliation":[{"name":"Graduate School of Public Health St. Luke's International University  Tokyo Japan"},{"name":"Department of Population and Quantitative Health Sciences University of Massachusetts Medical School  Worcester Massachusetts USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Long Quynh","family":"Khuong","sequence":"additional","affiliation":[{"name":"Hanoi University of Public Health  Hanoi Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anh Tuan","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Vietnam National Heart Institute  Hanoi Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anh Le Tuan","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Institute for Preventive Medicine and Public Health Hanoi Medical University  Hanoi Vietnam"},{"name":"Faculty of Health University of Tasmania  Hobart Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cham Thi","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Training Center and Scientific Management National Institute of Occupational Health and Environment  Hanoi Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ha Thi Thu","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Institute for Preventive Medicine and Public Health Hanoi Medical University  Hanoi Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thu Thi Ha","family":"Tran","sequence":"additional","affiliation":[{"name":"Institute for Preventive Medicine and Public Health Hanoi Medical University  Hanoi Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"An Thi Minh","family":"Dao","sequence":"additional","affiliation":[{"name":"Department of Population and Quantitative Health Sciences University of Massachusetts Medical School  Worcester Massachusetts USA"},{"name":"Department of Epidemiology, Institute for Preventive Medicine and Public Health Hanoi Medical University  Hanoi Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stuart","family":"Gilmour","sequence":"additional","affiliation":[{"name":"Graduate School of Public Health St. Luke's International University  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Minh","family":"Van Hoang","sequence":"additional","affiliation":[{"name":"Department of Population and Quantitative Health Sciences University of Massachusetts Medical School  Worcester Massachusetts USA"},{"name":"Hanoi University of Public Health  Hanoi Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,6,16]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM200001133420207"},{"issue":"3","key":"e_1_2_9_3_1","first-page":"525","article-title":"Unstable angina and non\u2013ST\u2010segment elevation myocardial infarction: Part I. initial evaluation and management, and hospital care","volume":"70","author":"Wiviott SD","year":"2004","journal-title":"Am Fam Phys"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(00)00889-5"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0733-8651(05)70072-2"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00059-003-2388-9"},{"key":"e_1_2_9_7_1","volume-title":"What Is Quality of Life?
