Cardiac Implantable Electronic Devices in Chagasic and Non-Chagasic Patients: A Critical Look at the Prognosis
This Short Editorial is referred by the Research article "Prognostic Evaluation of Chagasic and Non-Chagasic Patients Undergoing Pacemaker Implantation and Cardiac Resynchronization in a Tertiary Center".
Factors that may explain the results
One possible explanation for the lack of significant difference in prognosis between patients with and without Chagas disease may be related to improvements in clinical management and the structuring of health care for this population over the past few years., The study was conducted in a tertiary referral center, with likely access to cutting-edge technology and specialized monitoring. Specialized outpatient follow-up programs and adherence to recommended treatments may have reduced the disparities in outcomes between the two groups.
Furthermore, the study analyzed patient data across three different eras, which allowed for the assessment of possible changes over time. The fact that there were no differences in mortality between chagasic and non-chagasic patients in each of these eras reinforces the idea that progress in treatment, both clinical and surgical, may have diluted the adverse prognostic impact previously attributed to ChC.,
