Baseline characteristics of
the study patients
Baseline characteristics of the study participants are listed in Table
1. During a median 4.9 (4.7-5.1) years follow-up, 198 (18.4 %) patients
(group 1, mean age 72.1 ± 9 years; 59.6% female) experienced
progressive post-implant TR, whereas 877 patients (group 2, mean age
71.9 ± 12 years; 49.8% female) did not have progressive post-implant
TR. The percentage of female
individuals was higher in group 1 than group 2. Additionally, the
prevalence of atrial fibrillation (paroxysmal or non-paroxysmal) was
also higher in group 1. A higher percentage of sick sinus syndrome for
PPM was noted in group 1 (group 1 vs. group 2; 63.1% vs. 53.9%;
p=0.022). There was no difference in the distribution of ventricular
lead position, pacing QRS duration, ventricular pacing percentage, serum
creatinine level and medication used between the 2 groups.
