ABSTRACT

In this study, we present a comprehensive analysis of the electrocardiogram (ECG), coronary angiography, and optical coherence tomography (OCT) findings in three patients who experienced acute myocardial infarction (AMI) resulting from acute occlusion of the proximal and mid-segments of the right coronary artery (RCA). The findings demonstrate that the all-encompassing evaluation of both positive and negative coronary blood flow in the context of acute myocardial infarction (AMI) plays a decisive role in determining not only whether the ST segment on the electrocardiogram (ECG) leads pertaining to the affected myocardium undergoes changes, but also the inherent characteristics of said changes, whether it manifests as elevation, depression, or remains unchanged. However, the intricate relationship between ST-segment elevation and the composition of thrombus components within the infarct-related artery (IRA) remains an enigma that awaits further exploration.
