Baseline characteristics of the patients
Table 1 showed the baseline demographic data of the patients. The mean
age of the patients was 71 years in the CM group and 70 years in the MM
group. The prevalence of paroxysmal atrial fibrillation (PAF) was 55.6%
and 50.0% in the CM and MM groups, respectively. The
CHA2DS2-VASc scores were similar in the
two groups. The mean HAS-BLED score was also similar in the two groups.
There were significantly more patients with the combined procedure
(67.9% vs 45.8%, P=0.003) and with prior stroke (65.5% vs 50.8%,
P=0.048) in the MM group than in the CM group.
