Abstract
|
|
Women with CAD receive less frequently appropriate
diagnostic and therapeutic procedures. Aim of the study was to analyse 1.315
PM-implantations in 1.153 pts between 1982 an 1997 with regard to a possible
gender-difference in several factors.
Results. There was no difference between the sex- and
age-distribution and also between the ECG-indications, symptoms and etiology prior
PM-implantation.
Due to the pacing mode females received more frequently single-lead pacing devices (63% F
vs 56% M). Sequential PM were implanted more frequently in male (42 vs 32%) (p <
0.002).
No relationship could be found due to the age. But there was a relation to the underlying
ECG-diagnosis: in SSS females received VVI-PM in 76% and men in 70%, whereas the decision
for a DDD-PM in total AV-blocks was made in 53% of the men and in only 49% of the women
(ns).
Conclusion. In a large cohort of unselected PM patients collected
over a long time periode a gender difference could be found in relation to the type of
pacemaker used: women received more frequently single lead VVI pacing devices and less
frequently DDD-PM despite a lack of a difference in age, sex and underlying ECG-indication
for a PM.
