The objective of this study was to evaluate the effect of RFA on mean platelet volume (MPV), an indicator of platelet activity.  METHODS  A total of 95 patients undergoing RFA were included in the study. MPV was measured before and one month after the procedure. The control group was formed by 83 individuals of the same sex and age as those in the study group.  RESULTS  Beta-blockers, non-dihydropyridine calcium channel blockers, and acetylsalicylic acid use was higher in the ablation group compared with the control group. Other baseline clinical characteristics and baseline hemoglobin, white blood cell count, platelet count, and MPV values were similar between the ablation and control groups. In the ablation group, baseline and post-procedural hemoglobin, white blood cell counts were similar. However, postprocedural MPV values were higher, and platelet counts were lower compared with the preprocedural values.  CONCLUSION  Our results indicate that MPV values are higher after RFA compared with baseline values.<\/jats:p>","DOI":"10.1590\/1806-9282.65.8.1080","type":"journal-article","created":{"date-parts":[[2019,9,11]],"date-time":"2019-09-11T19:26:38Z","timestamp":1568229998000},"page":"1080-1085","source":"Crossref","is-referenced-by-count":1,"title":["Radiofrequency catheter ablation increases mean platelet volume"],"prefix":"10.1590","volume":"65","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6480-4935","authenticated-orcid":false,"given":"Fatih","family":"Aksoy","sequence":"first","affiliation":[{"name":"Suleyman Demirel University,  Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","published-online":{"date-parts":[[2019,8]]},"reference":[{"issue":"1","key":"ref1","doi-asserted-by":"crossref","first-page":"47","DOI":"10.2174\/138161211795049804","article-title":"Mean platelet volume: a link between thrombosis and inflammation?","volume":"17","author":"Yuri Gasparyan AY","year":"2011","journal-title":"Current Pharm Des"},{"issue":"6","key":"ref2","doi-asserted-by":"crossref","first-page":"554","DOI":"10.1590\/1806-9282.64.06.554","article-title":"Platelets volume indexes and cardiovascular risk factors","volume":"64","author":"Batista TR","year":"2018","journal-title":"Rev Assoc Med Bras"},{"issue":"8","key":"ref3","doi-asserted-by":"crossref","first-page":"1125","DOI":"10.1007\/s00296-009-1345-1","article-title":"Mean platelet volume in patients with rheumatoid arthritis: the effect of anti-TNF-\u03b1 therapy","volume":"30","author":"Gasparyan AY","year":"2010","journal-title":"Rheumatol Int"},{"issue":"2","key":"ref4","first-page":"271","article-title":"Influence of platelet volume on the ability of prostacyclin to inhibit platelet aggregation and the release reaction","volume":"105","author":"Jakubowski JA","year":"1985","journal-title":"J Lab Clin Med"},{"issue":"4","key":"ref5","doi-asserted-by":"crossref","first-page":"542","DOI":"10.1016\/0002-9343(78)90571-5","article-title":"Heterogeneity of platelet function.
