NCT07058857

Brief Summary

The goal of this clinical trial is to learn the effect of low level tragus stimulation (LLTS) on echocardiographic parameter in patient with ST-segment Elevation Myocardial Infarction (STEMI) who undergo primart percutaneous coronary intervention (PPCI). It will also learn about the safety of LLTS in such setting. The main questions, it aims to answer are compared with sham control: Does LLTS could alter left ventricular ejection fraction in patients with STEMI? Does LLTS could alter wall motion score index in patients with STEMI? Does LLTS could alter diastolic dysfunction in patients with STEMI? Researchers will compare LLTS to sham LLTS control to see if LLTS have benefit in participants with STEMI participants will divided into two group i.e. treatment group vs control (sham/placebo) group.. Both groups undergo transthoracal echocardiographi examination before and after PPCI..
