Tiempo puerta-aguja de fibrinólisis en pacientes con infarto agudo de miocardio con elevación del ST (IAMCEST) en el Hospital Teodoro Maldonado Carbo en el periodo 2023-2024.

Abstract

Introduction: Ischemic heart disease is one of the main causes of death in Ecuador. Restoring coronary blood flow is critical to reducing myocardial damage, preserving ventricular function, and reducing mortality, so its success depends on the time of treatment initiation. Objective: To calculate the door- to-needle time of fibrinolysis in ST-segment elevation acute myocardial infarction (STEMI) at the Teodoro Maldonado Carbo Hospital in the period 2023-2024. Methodology: This is an observational, descriptive, retrospective and cross-sectional study with a sample of 101 patients with STEMI undergoing fibrinolysis. Results: The mean age was 65.45 ± 10.71 years. 79.21% of the sample were male. High blood pressure and diabetes mellitus are the most frequent comorbidities. The average therapeutic window time is 4.7 ± 2.97 hours. The average door-to-needle time is 18.36 ± 8.66 minutes. The average total ischemia time is 300.79 ± 177.54 minutes. Heart failure (7.92%) is the most common cardiovascular complication. 14.85% died during the hospital stay. Conclusion: A door-to-needle time of less than 30 minutes reduces the risk of in-hospital mortality.
