The aim of the present article was to investigate changes in circadian BP profile parameters using two\u2010step statistical approach by Fourier analysis in relation to day and night urinary catecholamine excretion in 35 patients with pheochromocytoma (mean age 42 \u00b1 19 years). Twenty\u2010four\u2010hour ambulatory BP measurements (ABPM) were obtained using the SpaceLabs 90,207 monitor. Daytime and night\u2010time urine collection was obtained in all patients to determine circadian catecholamine excretion. Fourier analysis was applied to estimate measures of BP circadian rhythm in ABPM, including the highest (Max) and lowest (Min) systolic (SBP) and diastolic (DBP) BP values, norad (ampSBP, ampDBP), and early acrophase (APSBP, APDBP). The Fourier indices of circadian BP rhythm were: MaxSBP 153 \u00b1 28 mm Hg, MaxDBP 99 \u00b1 16 mm Hg, MinSBP 117 \u00b1 17 mm Hg, MinDBP 69 \u00b1 11 mm Hg, ampSBP 18 \u00b1 8 mm Hg, ampDBP 14 \u00b1 5 mm Hg, APSBP 10 \u00b1 5 (h), and APDBP 11 \u00b1 3 (h). Urine noradrenaline (NA), adrenaline (A), and dopamine (DA) excretion during the day (d) and night (n) were: dNA 103.5 \u00b1 89.8 \u03bcg\/14 h, nNA 52 \u00b1 70.8 \u03bcg\/10 h, dA 13.2 \u00b1 17.9 \u03bcg\/14 h; nA 6.13 \u00b1 9.6 \u03bcg\/10 h, dD 181.8 \u00b1 87.3 \u03bcg\/14 h, and nD 89.3 \u00b1 59.8 \u03bcg\/10 h. A positive correlation was observed between urine dNa excretion and MaxDBP (<jats:italic>r<\/jats:italic>= 0.37, <jats:italic>P<\/jats:italic> &lt; 0.05), and urine nNA and urine dA excretion were correlated with APDBP (<jats:italic>r<\/jats:italic>= 0.47, <jats:italic>r<\/jats:italic>= 0.35, respectively, both <jats:italic>P<\/jats:italic> &lt; 0.05). Thus, in addition to the effect on mean 24\u2010h BP values, catecholamines released by tumor may also disturb circadian BP rhythm in patients with pheochromocytoma.<\/jats:bold> <\/jats:p>","DOI":"10.1196\/annals.1353.008","type":"journal-article","created":{"date-parts":[[2006,11,14]],"date-time":"2006-11-14T00:28:06Z","timestamp":1163464086000},"page":"79-85","source":"Crossref","is-referenced-by-count":2,"title":["Catecholamine Excretion and Circadian Blood Pressure Profile in Patients with Pheochromocytoma"],"prefix":"10.1111","volume":"1073","author":[{"given":"ELZBIETA","family":"DABROWSKA","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JACEK","family":"LEWANDOWSKI","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"PIOTR","family":"JEDRUSIK","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"BARTOSZ","family":"SYMONIDES","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"BOZENA","family":"WOCIAL","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"MARIUSZ","family":"LAPINSKI","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"ZBIGNIEW","family":"GACIONG","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2006,9,7]]},"reference":[{"key":"e_1_2_5_2_2","doi-asserted-by":"publisher","DOI":"10.1097\/00004872-199715120-00056"},{"key":"e_1_2_5_3_2","doi-asserted-by":"publisher","DOI":"10.1161\/hy1201.097302"},{"key":"e_1_2_5_4_2","doi-asserted-by":"publisher","DOI":"10.1097\/00004872-200309000-00017"},{"key":"e_1_2_5_5_2","first-page":"397","article-title":"Effect of removal of pheochromocytoma on diurnal variability of blood pressure, heart rhythm and excretion of catecholamines","volume":"4","author":"Dabrowska B.","year":"1990","journal-title":"J.
