Results from these patients were compared to those of 39 age and sex-matched normotensive controls. Sixteen (26.2%) of the hypertensive patients and 6 (15.4%) of the controls had the sickle-cell trait (HbAS); the rest were normal homozygotes (HbAA).<\/jats:p>\n Although there were no significant difference between WBF in the HbAA hypertensive and control groups, the former had a significantly lower EF than the latter (p < 0.025). Both WBF and EF were highly significantly decreased in the HbAS-hypertensives (p < 0.001). Significant differences in H'ct and Hb lev els between HbAA-hypertensives and controls were attributed to sex rather than to hypertension per se. Plasma fibrinogen concentration values were consist ently and significantly elevated in all hypertensives irrespective of sex or haemo globin genotype. In contrast to the HbAA-hypertensives, all 16 HbAS-hypertensives had a persistently raised diastolic blood pressure above 90 mm Hg, suggesting that these patients are either resistant or are less responsive to conventional anti-hypertensive therapy.<\/jats:p>\n A more extensive follow-up study is in progress to assess the possible rela tionship of these parameters and blood pressure, particularly in hypertensive individuals with sickle-cell trait (HbAS).<\/jats:p>","DOI":"10.1177\/000331978503600607","type":"journal-article","created":{"date-parts":[[2007,11,26]],"date-time":"2007-11-26T17:46:29Z","timestamp":1196099189000},"page":"379-386","source":"Crossref","is-referenced-by-count":5,"title":["Haemorheological Parameters in Hypertensive Nigerians With and Without Sickle-Cell Trait"],"prefix":"10.1177","volume":"36","author":[{"given":"H.L.","family":"Reid","sequence":"first","affiliation":[{"name":"Departments of Physiology and Medicine, School of Medicine, College of Medical Sciences, University of Benin, Benin City, Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.O.","family":"Anah","sequence":"additional","affiliation":[{"name":"Departments of Physiology and Medicine, School of Medicine, College of Medical Sciences, University of Benin, Benin City, Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1985,6,1]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-8703(66)90440-6"},{"key":"atypb2","first-page":"241","volume":"32","author":"Oviasu VO","year":"1979","journal-title":"Trop Geogr Med"},{"key":"atypb3","first-page":"26","volume":"25","author":"Johnson TO","year":"1971","journal-title":"Brit J Prev Sco Med"},{"key":"atypb4","volume-title":"Oral communication No. 64 at the 2nd European Conference on Clinical Haemorheology","author":"Chien Shu"},{"key":"atypb5","volume-title":"Oral communication No. 204 at the 3rd European Conference on Clinical Haemorheology","author":"Proenca MC"},{"key":"atypb6","doi-asserted-by":"publisher","DOI":"10.1007\/BF02591099"},{"key":"atypb7","author":"Oli JM","year":"1984","journal-title":"Trop Geogr Med"},{"key":"atypb8","first-page":"43","volume":"34","author":"Reid HL","year":"1982","journal-title":"Trop Geogr Med"},{"key":"atypb9","doi-asserted-by":"publisher","DOI":"10.1136\/jcp.29.9.855"},{"key":"atypb10","doi-asserted-by":"publisher","DOI":"10.1136\/jcp.14.4.356"},{"key":"atypb11","first-page":"211","volume":"47","author":"Dormandy JA","year":"1970","journal-title":"Ann Roy Surg Eng"},{"key":"atypb12","doi-asserted-by":"publisher","DOI":"10.1016\/0002-8703(69)90139-2"},{"key":"atypb13","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9681(65)90151-7"},{"key":"atypb14","volume-title":"Oral communication No. 41 at the 3rd European Conference on Clinical Haemorheology","author":"Chien Shu"},{"key":"atypb15","doi-asserted-by":"publisher","DOI":"10.1001\/archinte.1956.00250210061005"},{"key":"atypb16","volume-title":"Oral communication No. 141 at the 3rd European Conference on Clinical Haemorheology","author":"Solerete SB"},{"key":"atypb17","doi-asserted-by":"publisher","DOI":"10.1177\/000331977802900112"}],"container-title":["Angiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/000331978503600607","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/000331978503600607","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T10:14:19Z","timestamp":1777371259000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/000331978503600607"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1985,6]]},"references-count":17,"journal-issue":{"issue":"6","published-print":{"date-parts":[[1985,6]]}},"alternative-id":["10.1177\/000331978503600607"],"URL":"https:\/\/doi.org\/10.1177\/000331978503600607","relation":{},"ISSN":["0003-3197","1940-1574"],"issn-type":[{"value":"0003-3197","type":"print"},{"value":"1940-1574","type":"electronic"}],"subject":[],"published":{"date-parts":[[1985,6]]}}}
