Fatores clínicos e sociodemográficos associados à dependência de marca-passo

Abstract

Background: Pacemaker dependence (MPD) is a little studied entity. Knowing the clinical and demographic profile of patients with this condition is of fundamental importance to prevent serious and catastrophic situations, such as sudden death. In addition, it is a way to prevent these patients from reaching the emergency room, often occupying beds for long stays because there are no specialists who can deal with their problem. Objective: The objective is to measure the frequency of MPD and to evaluate the clinical and demographic variables in a sample of patients with MCP (Permanent Pacemaker) who received these devices by bradycardia. Methods: The MPD criteria were initially established, and soon after, searches were performed in the medical records of patients with MCP that contained all the medical and demographic information necessary for the purpose of the study. Results: The 291 individuals included in the present study were aged 20 to 102 years (69.6 ± 14.7) and one time of implantation of the MCP from zero to 220 months (45.0 ± 44.8). The frequency of MPD patients was 50.9% in the sample studied. The variables, Chagas disease, AV block and the use of Amiodarone were associated with a higher risk of MPD. Conclusion: Of the patients with pacemakers studied, it was verified that PMD was present in a little more than half of the sample and that the variables, Chagas disease, AV block and the use of Amiodarone were positively associated with the outcome.
