Ischemic heart disease is one of the leading causes of morbidity and death worldwide. Consequently, myocardial infarctions are often encountered in clinical and forensic autopsies, and diagnosis can be challenging, especially in the absence of an acute coronary occlusion. Precise histopathological identification and timing of myocardial infarction in humans often remains uncertain while it can be of crucial importance, especially in a forensic setting when third person involvement or medical responsibilities are in question. A proper post-mortem diagnosis requires not only up-to-date knowledge of the ischemic coronary and myocardial pathology, but also a correct interpretation of such findings in relation to the clinical scenario of the deceased. For these reasons, it is important for pathologists to be familiar with the different clinically defined types of myocardial infarction and to discriminate myocardial infarction from other forms of myocardial injury. This article reviews present knowledge and post-mortem diagnostic methods, including post-mortem imaging, to reveal the different types of myocardial injury and the clinical-pathological correlations with currently defined types of myocardial infarction.

Background: Low-density lipoprotein cholesterol (LDL-C) is a well-recognized risk factor for cardiovascular diseases. However, several clinical studies demonstrated an inverse association between LDL-C and mortality risk in patients with acute myocardial infarction (AMI), known as the lipid paradox. This study aims to investigate the potential impact of inflammation on the association between LDL-C levels and mortality risks.

Background: Percutaneous coronary intervention of severely calcified lesions is limited by inadequate stent expansion and poor clinical outcomes. Over the past decade, several devices and techniques have been developed for calcium modification and lesion preparation. Intravascular lithotripsy (IVL) is a novel tool in this context.

Through bioinformatics screening, we previously found that AlkB homolog 5 (ALKBH5) expression, an mA demethylase, was higher in patients with heart failure than in the normal population. This study aimed to investigate the molecular mechanisms by which ALKBH5 regulates heart failure. We established a myocardial infarction (MI)-induced heart failure model in rats in vivo and an in vitro hypoxia model using rat primary cardiac fibroblasts (RCFs).

Aims: To assess the impact of Glucose-6-phosphate dehydrogenase (G6PD) deficiency, an enzymatic deficiency prevalent in individuals of African or Asian descent, on Hemoglobin A1c (HbA1c) levels, diabetes medication purchases, and the cumulative incidence of diabetes related complications.
Methods: A large cohort study was conducted within a national health organization, comparing 3,913 G6PD-deficient patients to a matched control group without G6PD deficiency over two decades. The main measures and outcomes were the HbA1c levels, patterns of diabetes medication purchases, and the incidence of severe diabetes-related complications.

Introduction: Various cardiovascular thrombo-embolic clinical entities use combined ATS for prevention and treatment. After PCI, AF patients are typically prescribed DOAC, DAPT/SAPT, as component of ATS to minimize stroke risk and treat pulmonary embolism and venous thromboembolism. Some small observational studies have shown that a combined ATS can clear small thrombi in LV dysfunction and/or apical aneurysms.
