The mean degree of stenosis was reduced from 77 \u00b112% to 29 \u00b115% and the mean systolic pressure gradient from 78 \u00b118 to 25 \u00b19 mmHg. Apart from a reversible spasm in one patient, PTCA was free of acute complications. Despite long\u2010term treatment with nifedi\u2010pine, nitrates, and warfarin (patients 1 to 5) or aspirin (patients 6 and 7) restenoses occurred in 4 of 7 patients. An aortocoronary bypass was necessary in 2 patients, 3 respectively 6 weeks after PTCA because of tighter re\u2010stenoses than before PTCA. Another patient underwent successful repeat angioplasty after 6 weeks and remained improved. During a mean follow\u2010up observation of 21 months (6 to 30 months), 4 patients were asymptomatic, even without medication. In one of these patients, the follow\u2010up angiography (6 months after PTCA) demonstrated a restenosis. These results suggest that PTCA can be performed without a higher risk of acute complications in patients with variant angina. Although the recurrence rate is high in these patients, sustained clinical improvement was achieved in a substantial percentage of patients in our study.<\/jats:p>","DOI":"10.1002\/clc.4960071206","type":"journal-article","created":{"date-parts":[[2009,2,5]],"date-time":"2009-02-05T00:42:25Z","timestamp":1233794545000},"page":"654-659","source":"Crossref","is-referenced-by-count":3,"title":["Role of percutaneous transluminal coronary angioplasty in patients with variant angina and coexistent coronary stenosis refractory to maximal medical therapy"],"prefix":"10.1002","volume":"7","author":[{"given":"F.","family":"Leisch","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"W.","family":"Herbinger","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P.","family":"Br\u00fccke","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2009,2,4]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(83)90346-6"},{"key":"e_1_2_1_3_1","first-page":"II\u2010331","article-title":"Recurrence of stenosis after successful percutaneous transluminal coronary angioplasty (abstr.)","volume":"66","author":"Dangoisse V","year":"1982","journal-title":"Circulation"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.66.4.695"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM197907123010201"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM197809282991305"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-2008-1069754"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(82)90223-5"},{"key":"e_1_2_1_9_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM197907123010209"},{"key":"e_1_2_1_10_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.61.2.296"},{"key":"e_1_2_1_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(78)90691-4"},{"key":"e_1_2_1_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/0167-5273(83)90032-3"},{"key":"e_1_2_1_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-8703(83)90640-3"},{"key":"e_1_2_1_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-8703(81)90405-1"}],"container-title":["Clinical Cardiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fclc.4960071206","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/clc.4960071206","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,19]],"date-time":"2023-10-19T22:07:26Z","timestamp":1697753246000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/clc.4960071206"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1984,12]]},"references-count":13,"journal-issue":{"issue":"12","published-print":{"date-parts":[[1984,12]]}},"alternative-id":["10.1002\/clc.4960071206"],"URL":"https:\/\/doi.org\/10.1002\/clc.4960071206","archive":["Portico"],"relation":{},"ISSN":["0160-9289","1932-8737"],"issn-type":[{"value":"0160-9289","type":"print"},{"value":"1932-8737","type":"electronic"}],"subject":[],"published":{"date-parts":[[1984,12]]}}}
