Evaluating the effectiveness of coronary interventions and thrombolysis using myocardial strain in ST-elevation ACS patients
Abstract
Background.Reperfusion therapies, including primary percutaneous coronary intervention (PCI), thrombolysis, and salvage PCI, are crucial for treating patients with ST-segment elevation myocardial infarction (STEMI). Evaluating their effectiveness through myocardial strain provides valuable insights into myocardial recovery.
Materials and methods. A total of 200 STEMI patients underwent reperfusion therapy via primary thrombolysis, primary PCI, or salvage PCI. Myocardial strain was assessed using echocardiography at three stages: before reperfusion, immediately after reperfusion, and six months post-procedure.
Results.Patients treated with primary PCI demonstrated significantly better recovery in myocardial strain compared to those who received thrombolysis or salvage PCI. The six-month follow-up confirmed sustained improvement in myocardial contractility among primary PCI patients.
Conclusion. Primary PCI is the most effective reperfusion method for restoring myocardial function in STEMI patients, as evidenced by superior myocardial strain recovery. Early identification and application of appropriate reperfusion strategies are essential for optimizing patient outcomes.
