Background Fibrinolysis using streptokinase or tenecteplase remains the primary reperfusion strategy for ST-elevation myocardial infarction (STEMI) in many Asian countries, including Malaysia. Comparative outcomes of these two fibrinolytic agents in the Asian population were inconclusive despite being widely used. Aim We aimed to assess and compare the outcomes of streptokinase versus tenecteplase in STEMI reperfusion of an Asian population. Method This single-centre retrospective study analysed data on STEMI patients who received fibrinolytic therapy from 2016 to 2020 in the Emergency Department of the largest tertiary hospital in Malaysia. Total population sampling was used in this study. Based on the propensity score matching, 359 patients receiving streptokinase were matched against 359 patients receiving tenecteplase by incorporating 16 variables that potentially affect mortality. 30-day mortality, stroke and major bleeding were the primary outcome measures. Results There was no significant difference in 30-day mortality between streptokinase (n = 39, 11.2%) and tenecteplase (n = 46, 13.2%) groups (p = 0.418). The rates of ischemic strokes [streptokinase (n = 1, 0.3%) versus tenecteplase (n = 3, 0.9%), p = 0.624], intracranial haemorrhage [streptokinase (n = 3, 0.9%) versus tenecteplase (n = 1, 0.3%), p = 0.624] and major bleeding [streptokinase (n = 4, 1.1%) versus tenecteplase (n = 3, 0.9%), p = 0.624], were comparable for the two groups. The incidences of failed thrombolysis were significantly higher in the tenecteplase arm. Hypotension and allergic reaction were significantly higher in the streptokinase arm. Conclusion Streptokinase and tenecteplase are fibrinolytic agents with similar efficacy and safety in STEMI reperfusion therapy in our Asian population. [ABSTRACT FROM AUTHOR] |
