Acute coronary syndromes in patients with presence of ST-segment elevation in the anterior precordial leads indicates left anterior descending coronary artery occlusion. However, anterior ST-segment elevation has also been described in right ventricular myocardial infarction and is thought to be due to right coronary artery (RCA) occlusion. We present a rare case of isolated RVMI presenting with anterior ST-segment elevation due to proximal occlusion of a right coronary artery that was treated by primary coronary angioplasty. Primary coronary angioplasty and stenting of this artery was performed resulting in resolution of the chest pain and ST- segment elevation.

Background: Reduced effect of antiplatelet therapy has been reported in patients with ST-segment elevation myocardial infarction (STEMI). This could partly be explained by an increase of highly reactive immature platelets.
Objectives: To investigate changes in platelet maturity and reactivity after acute STEMI.

Objective: The aim of this paper is to discover differentially expressed genes related to ferroptosis (DEFRGs) in patients with ST-segment elevation myocardial infarction (STEMI) and to construct a reliable prognostic signature that incorporates key DEFRGs and easily accessible clinical factors.
Methods: We did a systematic review of Gene Expression Omnibus datasets and picked datasets SE49925, GSE60993, and GSE61144 for analysis. We applied GEO2R to find DEFRGs and overlapped them among the picked datasets.

Aim: Both clonal hematopoiesis of indeterminate potential (CHIP) and type 2 diabetes mellitus (T2DM) are conditions closely associated with advancing age. This study delves into the possible implications and prognostic significance of CHIP and T2DM in patients diagnosed with ST-segment elevation myocardial infarction (STEMI).
Methods: Deep-targeted sequencing employing a unique molecular identifier (UMI) for the analysis of 42 CHIP mutations-achieving an impressive mean depth of coverage at 1000 × -was conducted on a cohort of 1430 patients diagnosed with acute myocardial infarction (473 patients with T2DM and 930 non-DM subjects).

Introduction: Women increased risk of early mortality following ST-segment elevation myocardial infarction (STEMI) has been attributed to older age, more comorbidities, and less primary revascularization (PCI). Data on long-term outcomes is conflicting, and younger patients' specific evidence is limited.
Purpose: Compare gender outcomes following STEMI within a cohort of younger (≤55 years) and older (>55 years) individuals.

Background: Excimer laser coronary atherectomy (ELCA) is used for thrombotic culprit lesions in ST-segment elevation myocardial infarction (STEMI), but its effectiveness is still unclear.
Methods: Consecutive patients undergoing primary percutaneous coronary intervention within 24 h of onset were retrospectively investigated. Patients were divided into ELCA and non-ELCA groups.
