Abstract

Purposes : To evaluate clinical outcomes and identify factors associated with the success or failure of Streptokinase (SK) administration in patients with ST-elevation myocardial infarction (STEMI) at Yang Talad Hospital.

Study design : A retrospective descriptive study.

Materials and Methods : This study was conducted among 74 STEMI patients who received Streptokinase (SK) at Yang Talad Hospital between July 1, 2022, and September 30, 2025. Data were collected using standardized data collection forms, which included demographic information, initial clinical presentation, and treatment outcomes. Statistical analysis was performed using descriptive statistics, and associations were determined using Crude Odds Ratios (OR) at a significance level of p < .05

Main findings: The cohort was 58.1% male with a mean age of 66.72 years. The most frequent infarct location was the inferior wall (47.3%). Treatment efficacy showed that 59.5% of patients had persistent chest pain 90 minutes post-thrombolysis, and (40.5%) failed to achieve ST-segment resolution of less than (50.0%). The mortality rate was (10.8%). Infarction of the lateral wall was significantly associated with a reduction in chest pain compared to the anterior wall (p = .043). The strongest predictor of mortality was initial presentation with Killip Class IV, which increased the risk of death by 24.82 times (p = .004). Additionally, a median door-to-needle time of 63 minutes was observed, exceeding the 30-minute international standard.

Conclusion and Recommendations: Streptokinase therapy achieved successful reperfusion in approximately 60% of cases, with clinical severity upon admission being the primary determinant of survival. It is recommended to enhance the "Fast Track" system to reduce door-to-needle time to meet international standards. Furthermore, high-risk patients (Killip Class IV) require intensive monitoring and timely referral for rescue percutaneous coronary intervention (PCI).
