Key result

Paramedic-led pre-hospital care cuts treatment delays and improves survival in AMI.

Why the study?

Time-sensitive intervention is critical for survival in acute myocardial infarction, and the effectiveness of paramedic-led pre-hospital interventions on patient outcomes requires systematic evaluation.

Implication

Endorses paramedic-led prehospital ECG and treatment in AMI; extends time-to-reperfusion evidence to first responders.

Key Points

To systematically evaluate the clinical impact of paramedic-led pre-hospital interventions, including early diagnostics, pharmacotherapy, and catheterization laboratory activation, on outcomes in patients with acute myocardial infarction.
Conducted a systematic review of peer-reviewed studies published between 2015 and 2024.
Evaluated pre-hospital strategies including electrocardiogram acquisition and transmission, pre-hospital thrombolysis, antiplatelet administration, pain management, and direct catheterization laboratory activation.
Analyzed patient-centered and healthcare metrics including door-to-balloon time, mortality rates, reperfusion success, myocardial salvage, and return of spontaneous circulation.
Pre-hospital electrocardiogram acquisition and telemedicine transmission reduced door-to-balloon times by 20 to 45 minutes, addressing a risk where every 30-minute delay increases 1-year mortality by a relative 7.5%.
Pre-hospital thrombolysis administered within the first hour of symptom onset reduced mortality by 17% and increased the probability of artery patency at hospital arrival by 30% compared to in-hospital administration.
Pre-hospital aspirin administration was associated with a 23% reduction in mortality, while paramedic activation of the catheterization laboratory prior to hospital arrival was associated with up to a 15% improvement in 30-day survival.

Do paramedic-led pre-hospital interventions reduce treatment delays and improve mortality in patients with acute myocardial infarction?

Population

A systematic review of studies published between 2015 and 2024 evaluating the impact of paramedic-led pre-hospital interventions on patients with acute myocardial infarction.

Intervention

Paramedic-led pre-hospital interventions including electrocardiogram (ECG) acquisition and transmission, pre-hospital thrombolysis, administration of antiplatelet agents (e.g., aspirin), pain management, and activation of catheterization laboratories.

Comparator

Delayed in-hospital treatment or standard care without early paramedic-led intervention.

Outcome

Treatment delays (door-to-balloon time) and mortality rates.hard clinical

Paramedic-led pre-hospital interventions, including early ECG transmission, antiplatelet therapy, and thrombolysis, are critical for reducing ischemic time and improving survival in acute myocardial infarction.

Limitations

Heterogeneity in study designs and outcome measures
Disparities in training, resource allocation, and protocols across regions
Geographic research gap with limited data from the Middle East, Africa, and Asia
