Our objective was to evaluate the association between immigrant status and CAD among immigrants.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Methods and Results<\/jats:title>\n                    <jats:p xml:lang=\"en\">Initial coronary angiography performed for stable CAD from 2012 to 2021 in Ontario, Canada was examined. Immigrants were categorized by their country of birth into 7 world regions. The primary outcome was the rate of obstructive CAD, defined as the presence of left main stenosis \u226550% or major epicardial vessel stenosis \u226570%. Multivariable logistic regression analyses were conducted to compare the adjusted odds of obstructive CAD among long\u2010term residents and immigrants, and then within immigrant groups. Our cohort included 208\u2009363 long\u2010term residents and 36\u2009139 immigrants; the immigrants were substantially younger than the long\u2010term residents (61.3 versus 66.6\u2009years). Male immigrants had 12.0% higher adjusted odds (95% CI, 1.17\u20131.24) of having obstructive CAD than long\u2010term residents, whereas no significant difference was observed among female immigrants and long\u2010term residents. There was also substantial variation in CAD among immigrants based on their country of origin. For example, male immigrants from South Asia had 49.0% higher adjusted odds of having CAD, whereas patients from Africa (0.75) and the Caribbean (0.63) had lower adjusted odds.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p xml:lang=\"en\">We observed earlier presentations for cardiac catheterization among immigrants with stable CAD and higher adjusted odds of having obstructive CAD among male immigrants compared with long\u2010term residents of Canada. Rates of obstructive CAD varied significantly by their region of birth.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1161\/jaha.124.037534","type":"journal-article","created":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T06:56:46Z","timestamp":1745391406000},"update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Variations of the Extent of Obstructive Coronary Artery Disease Among Canadian Immigrants"],"prefix":"10.1161","volume":"14","author":[{"given":"Hirmand","family":"Nouraei","sequence":"first","affiliation":[{"name":"University of Toronto","place":["Toronto, Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9882-7564","authenticated-orcid":false,"given":"Feng","family":"Qiu","sequence":"additional","affiliation":[{"name":"ICES (formerly Institute for Clinical Evaluative Sciences), Toronto","place":["Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olivia","family":"Haldenby","sequence":"additional","affiliation":[{"name":"ICES (formerly Institute for Clinical Evaluative Sciences), Toronto","place":["Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7105-7931","authenticated-orcid":false,"given":"Husam","family":"Abdel\u2010Qadir","sequence":"additional","affiliation":[{"name":"University of Toronto","place":["Toronto, Canada"]},{"name":"ICES (formerly Institute for Clinical Evaluative Sciences), Toronto","place":["Canada"]},{"name":"Women\u2019s College Hospital","place":["Toronto, Canada"]},{"name":"The Peter Mink Cardiac Centre","place":["Toronto, Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9056-5309","authenticated-orcid":false,"given":"Saswata","family":"Deb","sequence":"additional","affiliation":[{"name":"Sunnybrook Health Sciences Centre","place":["Toronto, Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0285-6569","authenticated-orcid":false,"given":"Mina","family":"Madan","sequence":"additional","affiliation":[{"name":"Sunnybrook Health Sciences Centre","place":["Toronto, Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3598-3628","authenticated-orcid":false,"given":"Baiju R.","family":"Shah","sequence":"additional","affiliation":[{"name":"University of Toronto","place":["Toronto, Canada"]},{"name":"ICES (formerly Institute for Clinical Evaluative Sciences), Toronto","place":["Canada"]},{"name":"Sunnybrook Health Sciences Centre","place":["Toronto, Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1936-5133","authenticated-orcid":false,"given":"Maneesh","family":"Sud","sequence":"additional","affiliation":[{"name":"University of Toronto","place":["Toronto, Canada"]},{"name":"ICES (formerly Institute for Clinical Evaluative Sciences), Toronto","place":["Canada"]},{"name":"Sunnybrook Health Sciences Centre","place":["Toronto, Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2953-2540","authenticated-orcid":false,"given":"Manav V.","family":"Vyas","sequence":"additional","affiliation":[{"name":"University of Toronto","place":["Toronto, Canada"]},{"name":"ICES (formerly Institute for Clinical Evaluative Sciences), Toronto","place":["Canada"]},{"name":"St. Michael\u2019s Hospital\u2013Unity Health Toronto","place":["Toronto, Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8464-1080","authenticated-orcid":false,"given":"Harindra C.","family":"Wijeysundera","sequence":"additional","affiliation":[{"name":"University of Toronto","place":["Toronto, Canada"]},{"name":"ICES (formerly Institute for Clinical Evaluative Sciences), Toronto","place":["Canada"]},{"name":"Sunnybrook Health Sciences Centre","place":["Toronto, Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6840-8051","authenticated-orcid":false,"given":"Dennis T.","family":"Ko","sequence":"additional","affiliation":[{"name":"University of Toronto","place":["Toronto, Canada"]},{"name":"ICES (formerly Institute for Clinical Evaluative Sciences), Toronto","place":["Canada"]},{"name":"Sunnybrook Health Sciences Centre","place":["Toronto, Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_2_2_2","unstructured":"International Migration Outlook .
