Features of pregnancy in women with pacemaker

The aim of the study. To identify the features of the pregnancy course in patients with an implanted pacemaker (EP). Material and methods. The course of singleton pregnancy was analyzed in 68 women with an EP (main group) and in 60 women without cardiac pathology (comparison group). Results. In the main group, 39 women (57.4%) were primiparous, 29 (42.6%) were multiparous, in the comparison group — 41 (68.3%) and 19 (31.7%) women, respectively (p=0.20). The threat of termination of pregnancy in the first trimester was noted in 33.8% of women in the main group and in 16.7% of women in the comparison group, which is 2 times (p=0.044) lower, there were no statistically significant differences in the frequency of other complications. In women of the main group, the weight gain was 11 (9; 14) kg and was 18.5% (p=0.0019) less than in women of the comparison group — 13.5 (11.5; 15.5) kg. In general, pregnancy was complicated in 53 (77.9%) women of the main group and in 37 women (61.7%) of the comparison group (p=0.044). A correlation was found between the presence of cardiac pathology and the development of pregnancy complications (G=0.23, p=0.042). Cardiac complications were noted in 1 patient. In 3 cases, reimplantation of the pacemaker was required during pregnancy, it was performed at 26—38 weeks. Conclusion. In patients with a pacemaker, pregnancy was characterized by less weight gain and in the first half was often complicated by the threat of termination. Dynamic observation together with a cardiologist, timely treatment of complications allowed most women to successfully carry their pregnancies to term.
