STEMI telemedicine for 100 million lives

Area of Science:

• Cardiology
• Telemedicine
• Public Health

Background:

• Developing countries face challenges in timely diagnosis and treatment of ST-segment elevation myocardial infarction (STEMI).
• Suboptimal outcomes in STEMI patients are common in resource-limited settings.

Purpose of the Study:

• To evaluate the effectiveness of the Latin America Telemedicine Network (LATIN) in improving STEMI care.
• To assess the impact of a telemedicine hub-and-spoke model on STEMI patient outcomes in South America.

Main Methods:

• The LATIN network utilized a Hub and Spoke platform across four countries (Brazil, Colombia, Mexico, Argentina).
• Telemedicine command sites provided 24/7 ECG diagnosis and teleconsultation for STEMI at 355 centers.
• Patients were triaged at remote spokes, with STEMI cases directed to 47 Hubs for treatment.

Main Results:

• Over the study period, 780,234 patients were screened, with 8395 diagnosed with STEMI.
• 46.1% of STEMI patients received urgent treatment, and 78% underwent percutaneous coronary intervention.
• Average door-to-balloon time improved from 120 to 48 minutes, with an overall STEMI mortality of 5.2%.

Conclusions:

• Telemedicine effectively expands access to critical STEMI care for millions in underserved regions.
• The LATIN initiative provides a scalable model for reducing STEMI management disparities between developed and developing nations.
