Clinical characteristics in adults and children with vasovagal syncope / 中华心血管病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the clinical characteristics in adults and children with vasovagal syncope (VVS).</p><p><b>METHODS</b>Clinical data including head-up tilt table (HUTT) results were analyzed and compared in 136 children (mean age 12.3 +/- 2.7 years, 50 boys, 86 girls) and 119 adults (mean age 36.4 +/- 14.0 years, 29 men, 90 women) with VVS.</p><p><b>RESULTS</b>(1) There were more female VVS patients in adults group than that in children group (male and female ratio children group 11.7 and adults group 13.1, P = 0.033) in this cohort. (2) The incidence of chest distress in adults group was significantly higher than that in children group [45.4 (54/119) vs. 27.2% (37/136), P = 0.003] while the incidence of headache [10.9% (13/119) vs. 20.6% (28/136), P = 0.036] and abdominal pain in children group was significantly higher than that in adults group [7.6% (9/119) vs. 19.1% (26/136), P = 0.008]. (3) Incidences of muggy environment [22.8% (26/114) vs. 12.5% (17/136), P = 0.032] and urination VVS [9.7% (11/114) vs. 1.5% (2/136), P = 0.004] were significantly higher in adults group than those in children group. (4) The mean time of mixed response vasogal episode in adults group was significantly longer than that in children group in sublingual nitroglycerin head-up tilt table test (SNHUT) stage (5.04 +/- 2.27 min vs. 3.50 +/- 1.24 min, P = 0.036).</p><p><b>CONCLUSIONS</b>The incidences of chest distress, muggy environment and urination VVS were more often and the mean time of vasogal episode of mixed response in SNHUT stage was longer in adults VVS while the incidence of abdominal pain and headache was higher in children VVS patients compared to adults VVS patients.</p>
