Atrial High-Rate Episodes and Cerebral Ischemic Events in Chagasic Patients

A cohort study of 67 Chagasic patients with implantable electronic cardiac devices, followed at a university hospital in Salvador, Bahia, Brazil, between May 2016 and June 2017. The research, authored by Emanoela Lima Freitas and published in 2020, investigated the association between atrial high-rate episodes and silent cerebral ischemic events detected by computed tomography. Patients were followed for a mean of 98 days, with 11.9% exhibiting AHREs and 16.4% showing silent ischemic events.

Use Cases

• Predicting silent cerebral ischemic events based on the presence of atrial high-rate episodes (AHREs) ≥ 6 minutes.
• Analyzing the association between advanced age and ischemic event risk in Chagasic patients.
• Studying the relationship between atrial frequency (≥190 bpm) and cerebral outcomes in a specific patient cohort.

Strengths

• Study includes 67 patient records with specific demographic details (67.2% female, mean age 63.6 years).
• Follow-up period is quantified (mean 98 ± 28.8 days), providing a clear temporal scope.
• Results include specific odds ratios (e.g., OR 96.2 for AHREs) for independent predictors.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the single-center study in Bahia, Brazil.
