Telemetry-based insights: clinical indicators linked to unfavorable outcomes in heart failure.

OBJECTIVE

Evaluate the clinical profile of heart failure patients under telemetry and identify associations with unfavorable outcomes.

METHODS

Cross-sectional study from 2019 to 2024 at a public university hospital. Coronary Care Unit nurses collected data from electronic medical records, which were analyzed using SPSS®. The project was approved by the Ethics Committee (Nº. 2019-0046).

RESULTS

Out of 425 medical records, 43% showed events, primarily non-sustained ventricular tachycardia (14.8%). After arrhythmic events, 29.6% underwent urgent electrocardiogram, 30.1% had pharmacological adjustments, and 15.7% died after transfer to the Coronary Care Unit. Significant associations included unfavorable outcomes in males (p=0.038), while diabetes mellitus was protective (p=0.004). Previous arrhythmias were also associated with adverse outcomes. Notably, event incidence was significant within the first 10 days of telemetry.

CONCLUSION

Pre-existing arrhythmias and male sex were associated with composite unfavorable outcomes in heart failure patients remotely monitored by telemetry.
