Key result
Male sex and pre-existing arrhythmias are linked to higher unfavorable outcome rates during heart failure telemetry.
Why the study?
The clinical profile and associations with unfavorable outcomes in heart failure patients under telemetry monitoring were not well characterized.
Cross-Sectional (n=425)
No

In heart failure patients on telemetry, male sex and pre-existing arrhythmias are associated with composite unfavorable outcomes, with events primarily occurring within the first 10 days.
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.

Cruz et al. (2026) conducted a cross-sectional in Heart failure (n=425). Male sex and pre-existing arrhythmias vs. Female sex and absence of pre-existing arrhythmias was evaluated on Composite unfavorable outcomes (p=0.038). Male sex (P=0.038) and pre-existing arrhythmias were significantly associated with composite unfavorable outcomes in heart failure patients monitored by telemetry, with an overall event rate of 43%.
