Overview

• Researchers unveiled the findings at ACC Latin America 2025 in Mexico City, focusing on cardiac intensive care patients.
• The intervention delivered a 45-minute melody at about 15 decibels once daily for five consecutive days.
• Compared with standard care, the music group showed significant reductions in heart rate, systolic and diastolic blood pressure, and patient–ventilator asynchronies.
• Participants were alert adults without hearing impairment admitted between July and September 2024 in a cardiac ICU.
• The team framed the approach as a safe, low-cost complement to conventional care, while the results remain preliminary and await peer-reviewed publication and larger trials.
