Two cases of acute right ventricular infarction associated with acute extensive anterior myocardial infarction in the absence of inferior and/or posterior left ventricular infarction are presented. Such a combination is likely to occur from acute occlusion of the left anterior descending artery in the face of severe narrowing of the infundibular (conus) artery rather than from acute occlusion of the right coronary artery.

The purpose of this study was to explore the impact of papillary muscle (PPM) infarction on left atrial and ventricular strain parameters in patients with non-anterior ST-segment elevation myocardial infarction (NA-STEMI) using cardiovascular magnetic resonance (CMR). This retrospective study performed CMR scans on 88 consecutive patients with NA-STEMI (68 males, 65 ± 10.05 years).

To investigate how PD-L1 monoclonal antibodies (mAbs) affect the left ventricular function in mice with myocardial infarction (MI) and through what mechanisms they exert their effects. In vivo experiments were conducted using 27 female BALB/c mice, which were divided equally into 3 groups. Cardiac function was assessed by ultrasound.

Despite concerted efforts to rapidly identify patients with cardiogenic shock complicating acute myocardial infarction (AMI-CS) and provide timely revascularization, early mortality remains stubbornly high. While artificially augmenting systemic flow through the use of temporary mechanical circulatory support (tMCS) devices would be expected to reduce the rate of progression to multi-organ dysfunction and thereby enhance survival, reliable evidence for benefit has remained elusive with lingering questions regarding the appropriate selection of both patients and devices, as well as the timing of device implantation relative to other critical interventions. Further complicating matters are the resource-intensive multidisciplinary systems of care that must be brought to bear in this complex patient population.

Introduction And Objectives: Cardiopulmonary exercise testing (CPET) is the gold standard for quantifying aerobic functional capacity, yet it is costly and not widely available. The CLINIMEX Aerobic Fitness Questionnaire (C-AFQ) may be a practical alternative as it estimates oxygen consumption at peak exercise (VO peak) based on patients' responses to a list of activities with known energy requirements. However, its applicability in cardiac patients is unclear and has not yet been studied.

Left ventricular (LV) pseudoaneurysm, a rare occurrence, develops when a ruptured ventricle is encapsulated by the pericardium or scar tissue. Unlike free intrapericardial rupture, which often results in cardiac tamponade and fatal outcome, there are instances where the cardiac rupture remains contained, forming a pseudoaneurysm and averting immediate tamponade. We describe a 43-year-old male who underwent successful surgical repair of LV rupture following inferior wall myocardial infarction that resulted in the formation of a large pseudoaneurysm.
