Introduction

The opportunity in reperfusion therapy in patients with acute myocardial infarction is associated with sociodemographic, clinical and attention factors. Regardless of the reperfusion therapy used, the important thing is to minimize the time of total ischemia.

Objective

To determine the factors associated with the lack of opportunity in myocardial reperfusion therapy.

Method

The study was conducted with empirical analytical, quantitative, cross-sectional observational approach, factors associated with the lack of opportunity in myocardial reperfusion therapy were analyzed, using the ji squared test and calculating odds ratios to study the association with a level 95% confidence.

Results

256 patients who were admitted for emergencies with ACS were analyzed, 63% of the events occurred at night, weekend or holiday, 22% of the patients admitted with ST segment elevation, of these only 47% arrived in less than 12 hours after the onset of symptoms and 52%, the inappropriate ICPP was performed in a time greater than 90 minutes, related to the time of the event (p = 0.001); ECG time (p = 0.01), general doctor and urgentologist care time (p = 0.003) and hemodynamic cardiologist care time (p = 0.015).

Conclusions

More than half of the patients who arrived at the emergency department with elevated ST receive an inappropriate reperfusion therapy and it is related to the time of the event, ECG time, time of emergency medical attention and hemodynamics.
