ECG abnormalities were present in 75 patients; there were isolated Q waves in 20, an abnormal R wave in lead V<jats:sub>1<\/jats:sub> with or without inferior and\/or lateral Q waves in 21, and isolated ST\u2010T wave changes in 34 cases. Inferior abnormalities on the electrocardiogram were similar in patients with proximal or distal stenoses of the LCx, but an abnormal R wave in lead V<jats:sub>1<\/jats:sub> correlated with proximal LCx stenosis (p&lt;0.01). Lateral abnormalities were more common in stenoses of the obtuse marginal branch and proximal LCx than in distal stenosis (all p&lt;0.01). Compared with patients without myocardial infarction with or without ST\u2010T\u2010wave changes and those with infarction without an abnormal R wave in lead V<jats:sub>1<\/jats:sub>, patients with LCx\u2010related infarction and an abnormal R wave in lead V<jats:sub>1<\/jats:sub> associated with inferior and\/or lateral Q waves had larger left ventricular end\u2010diastolic and end\u2010systolic volumes, lower ejection fraction, higher incidence of total occlusion of proximal LCx without collateral vessels, and more cardiac events during follow\u2010up. This study suggests that an abnormal R wave in lead V<jats:sub>1<\/jats:sub> associated with lateral abnormalities on the standard electrocardiogram may be clinically useful in predicting proximal LCx stenosis and identifying a subset of postinfarction patients with left ventricular dysfunction due to a large infarct size.<\/jats:p>","DOI":"10.1002\/clc.4960140905","type":"journal-article","created":{"date-parts":[[2009,2,4]],"date-time":"2009-02-04T15:23:02Z","timestamp":1233760982000},"page":"720-724","source":"Crossref","is-referenced-by-count":4,"title":["Relationship between electrocardiographic patterns and angiographic features in isolated left circumflex coronary artery disease"],"prefix":"10.1002","volume":"14","author":[{"given":"Wei Feng","family":"Shen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christophe","family":"Tribouilloy","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean\u2010Philippe","family":"Lesbre","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2009,2,4]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.69.3.477"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.1810020305"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.72.2.292"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(87)90285-2"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(84)80390-3"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(84)80204-1"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.51.4.5"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(89)91037-0"},{"key":"e_1_2_1_10_2","doi-asserted-by":"crossref","first-page":"1025","DOI":"10.1093\/oxfordjournals.eurheartj.a061805","article-title":"Left ventricular response to exercise in patients with coronary artery disease: Relation to myocardial ischemia and effects of nifedipine","volume":"6","author":"Shen WF","year":"1985","journal-title":"Eur Heart J"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1097\/00004424-196904020-00005"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-8703(86)90549-1"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(85)90388-1"},{"key":"e_1_2_1_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(83)90343-0"},{"key":"e_1_2_1_15_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.61.5.973"},{"key":"e_1_2_1_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(88)91380-X"},{"key":"e_1_2_1_17_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.43.3.428"},{"key":"e_1_2_1_18_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8159.1989.tb01844.x"},{"key":"e_1_2_1_19_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(84)80204-1"},{"key":"e_1_2_1_20_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-8703(05)80274-1"}],"container-title":["Clinical Cardiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fclc.4960140905","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/clc.4960140905","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,23]],"date-time":"2023-10-23T07:33:01Z","timestamp":1698046381000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/clc.4960140905"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1991,9]]},"references-count":19,"journal-issue":{"issue":"9","published-print":{"date-parts":[[1991,9]]}},"alternative-id":["10.1002\/clc.4960140905"],"URL":"https:\/\/doi.org\/10.1002\/clc.4960140905","archive":["Portico"],"relation":{},"ISSN":["0160-9289","1932-8737"],"issn-type":[{"value":"0160-9289","type":"print"},{"value":"1932-8737","type":"electronic"}],"subject":[],"published":{"date-parts":[[1991,9]]}}}
