Introduction:

myocardial infarction is the main cause of death in adult patients. The election of the best strategy of revascularization requires of an interdisciplinary participation, which leads to the feedback concerning the use and effectiveness of thrombolysis.

Objective:

to determine the effectiveness of thrombolysis in the acute myocardial infarction in the emergency services at Abel Santamaria Cuadrado General Teaching Hospital during 2017.

Methods:

an observational, descriptive and cross-sectional research was conducted with patients suffering from acute myocardial infarction attending emergency services of Abel Santamaria Cuadrado General Teaching Hospital during 2017. The target group included 352 patients with acute myocardial infarction, and the sample was comprised of 252 patients who underwent thrombolysis. The techniques of processing and analysis were distributed in absolute and relative frequencies, using also the statistical chi-square test. Bioethical principles were met.

Results:

male sex and ages between 60 and 69 years old predominated. The complement of the treatment was initiated under the sis hours. As the main adverse reactions, hypotension and extrasystole stood up. The relief of the pain predominated and the regression of ischemic electrocardiographic changes as criteria of reperfusion.

Conclusions:

pharmacologic thrombolysis resulted effective in patients with acute myocardial infarction, decreasing the mortality rate and associated complications. Thrombolysis is shown as a secure reperfusion strategy applied to patients with SCACEST at Abel Santamaria Cuadrado General Teaching Hospital in Pinar del Río province.
