| Summary: | <b>Introduction:</b> The prevention of heart failure (HF) exacerbation is crucial for patient prognosis, and preventive treatment for potential symptoms and warning signs is essential in this context. The TriageHF © algorithm has been retrospectively validated and has demonstrated good correlation with HF episodes. This study analyzes the effectiveness of the TriageHF © algorithm in routine clinical practice, emphasizing the role of episode duration in its predictive capacity. <b>Materials and methods:</b> From October 2017 to October 2020, all patients who received a Medtronic Amplia DR implant were prospectively selected for analysis. To evaluate the algorithm’s diagnostic capacity, it was compared with the clinical diagnosis of HF episodes during follow-up. <b>Results:</b> The sustained moderate-risk (more than 7 days) and high-risk alerts both showed high positive predictive values (11.25% and 27.27%, respectively), along with an increase in the relative risk of HF, particularly in high-risk alerts (hazard ratio is 46.21 times higher than for sustained moderate-risk alerts). Furthermore, there was higher event-free survival in real low-risk alerts than in both sustained medium-risk and high-risk alerts (<i>p</i> < 0.01). <b>Conclusions:</b> TriageHF © can predict the worsening of patients with ICD CRT. Medium-risk alerts lasting less than 7 days do not pose a greater risk of HF episodes, while high-risk alerts, regardless of their duration, are highly correlated with HF episodes. |
