24 Feb 2025 • A new study highlights the role of heart rate fluctuations in predicting mortality outcomes for patients with acute myocardial infarction (AMI) admitted to the ICU.

Larger heart rate fluctuations within the first 24 hours post-admission were significantly associated with higher 30-day (HR = 1.76), 1-year (HR = 1.59), and 3-year (HR = 1.43) mortality rates. The analysis revealed a J-shaped curve relationship, with heart rate fluctuations of 28 beats/min linked to the best prognosis.

These findings suggest monitoring and managing heart rate early in ICU care could improve patient outcomes.
