3.1 Baseline clinical and echocardiographic characteristics
All baseline parameters are summarized in Table 1. A total of 150
patients were included in our study, with 50 patients in each group. 16
(32%) were female in control group with an average age of 59.34±7.05
years, 17 (34%) were female in paroxysmal AF group with an average age
of 57.78±8.36 years and 15 (30%) were female in persistent AF group
with an average age of 60.94±6.70 years. In our study, EAT thickness
differed significantly among control group (3.51±0.29mm), paroxysmal AF
group (5.11±0.84mm) and persistent AF group (6.26±0.80mm). And compared
with control group, LAD in paroxysmal AF group and persistent AF group
increased in turn. However, there was no significant difference in LVEF
among three groups. The baseline clinical characteristics among three
groups also had no statistical difference, such as age, gender, BMI, BSA
and so on.
