Tuberculosis (TB) continues to pose a significant public health burden in endemic regions, remaining a leading cause of morbidity and mortality. Although TB is associated with a range of complications, the occurrence of intracardiac thrombus is an exceptionally rare manifestation. We report the case of a 62-year-old male with active pulmonary TB, who had been on anti-tubercular therapy for one month and presented with recurrent syncope and exertional dyspnea. Transthoracic 2D echocardiography revealed a large, mobile thrombus in the left ventricular apex. Evaluation for underlying hypercoagulable states was unremarkable. The patient was managed with anticoagulation therapy in conjunction with ongoing anti-tubercular treatment. This case underscores the importance of clinical vigilance for rare thrombotic complications in TB to facilitate timely diagnosis and appropriate management.

Preterm birth, defined as delivery before 37 weeks of gestation, represents a global health concern linked to substantial cardiovascular risk later in life. Individuals born preterm, especially at earlier gestational ages, exhibit increased rates of hypertension, heart failure, and ischemic heart disease. The underlying mechanisms include disrupted fetal programming, impaired vascular remodeling, chronic neonatal inflammation, neuroendocrine immaturity, and epigenetic alterations. This review synthesizes current epidemiological evidence from large cohort studies and meta-analyses, integrating mechanistic insights from developmental biology. We discuss distinct prematurity categories—extremely preterm (< 28 weeks), very preterm (28–32 weeks), and moderate to late preterm (33–37 weeks)—highlighting their association with graded cardiovascular risk. Recent findings emphasize the role of non-transmitted parental genes and prenatal environmental toxic metal exposure as additional critical factors influencing fetal cardiovascular programming. A total of 57 articles, identified through a systematic search of PubMed, Embase, and Cochrane databases, were included to address these topics comprehensively. Early identification of preterm-born individuals as a high-risk cardiovascular group is essential for targeted screening, prevention, and interventions from childhood into adulthood. Future studies leveraging multi-omics and epigenetic approaches will further clarify these mechanisms, informing evidence-based guidelines to reduce cardiovascular morbidity associated with preterm birth.

Age-related atrial fibrillation (AF) is a common condition that has yet to be fully understood, with mechanisms to explain its development under investigation. Notably, cellular senescence, cardiac fibrosis, coronary ischemia, cardiac valvular disease, autonomic dysfunction, channelopathies, and immune system remodeling are processes that have been seen to occur with aging and ample evidence has shown their association with the development of AF. Despite robust therapeutic approaches, the incidence of AF continues to rise, suggesting that the dynamic, multi-faceted interactions leading to AF are incompletely understood. One of the newer mechanisms currently being investigated is the gut microbiome. Although more research is needed to understand its impact on the development of age-related AF and targets for therapies, the gut microbiome is a promising new avenue of research that may provide future benefits in AF prophylaxis or enhanced management. As the field works towards developing this knowledge, there are important questions to answer as to the optimal role of potential gut microbiome targeting therapies and their potential risks versus the benefits they provide. This commentary first summarizes the currently understood mechanisms contributing to age-related AF, which is then followed by an analysis of the current work investigating the role of the gut microbiome in the development of age-related AF, and concludes by highlighting notable questions to consider in future work on the role of the gut microbiome and its relationship to age-related AF.

L-Carnitine (LC) is integral to energy production and fatty acid metabolism, facilitating the transport of long-chain fatty acids into mitochondria for β-oxidation. It modulates metabolic pathways, including pyruvate dehydrogenase activity, proteolysis, and protein synthesis, while also having anti-inflammatory and antioxidant characteristics. LC can be commonly applied to win the battle against HIV and cancer cachexia. Also, it can be recruited with the aim of improving physical and cognitive functions in athletes and the elderly. Despite these benefits, long-term LC administration has been associated to cardiovascular risks due its conversion to trimethylamine-N-oxide (TMAO) by the gut microbiota. Elevated TMAO levels are linked to atherosclerosis, oxidative stress, and an increased risk of cardiovascular disease, diabetes, and chronic kidney disease. Managing TMAO levels using dietary treatments and gut microbiota-targeting techniques, such as probiotics, may reduce these risks. This comprehensive review presents the state-of-the-art information on LC’s dual role, emphasizing the balance between its therapeutic potential and the risks of prolonged supplementation. It aims to guide clinicians and researchers in optimizing LC’s benefits while addressing its long term cardiovascular safety concerns.

By offering their expertise, reviewers help authors improve their work and also support editors in selecting high-quality studies, thereby reinforcing the integrity of scientific literature. Much like in a Sergio Leone film, your manuscript encounters three possible types of reviewers on its editorial journey: the Good, the Bad, and the Ugly. The Good Reviewer is, for reasons unknown, favorably disposed toward both you and your manuscript. They find it “well-written, with literary and enjoyable style”, “original and timely”, and addressing a topic that is “scientifically and socially relevant”. Their comments are respectful, constructive, and focused on minor but meaningful improvements. Unfortunately, the Good Reviewer is as rare as a white unicorn; some researchers reach the end of their careers without ever encountering one, leading them to question their very existence. The Bad Reviewer is both bad at reviewing and a bad influence on your work. They reject your manuscript, but their reasons are vague and unconvincing. Their objections are often asinine, and when you respond thoroughly and decisively, they counter with even more nonsensical arguments. They may pressure you to cite irrelevant literature—often their work or that of their colleagues. In the end, your once-solid and cohesive manuscript emerges in a far worse state than the original. None of this would have been possible without the Bad Reviewer, who, unleashed by a negligent editor, exerts their detrimental influence on your article. The Ugly Reviewer appears with unsettling regularity—at least once a month. They believe your article is truly terrible, and often, they are right. The Ugly Reviewer, though harsh, is no fool. Their critiques are brutal and unforgiving, yet accurate. Years later, you may find yourself grateful to them for preventing you from publishing work that, in hindsight, would have irreparably tarnished your already modest scientific reputation.

The oxidation of lipoproteins has a key role in the development of atherosclerosis, a condition where plaque builds up in artery walls. Research shows that when low-density lipoprotein (LDL) oxidizes, it speeds up atherosclerosis. Oxidized LDL (Ox-LDL) causes many pathologic scenarios that lead to atherosclerosis. It was suggested as a fundamental player in endothelial dysfunction, creating foam cells, and triggering inflammation in artery walls. How Ox-LDL contributes and interacts with specific receptors on endothelial cells is crucial to these effects. This article aims to shed light on LDL oxidation, the stages of the process, and how Ox-LDL promotes atherosclerosis. A comprehensive search was conducted across various databases, including PubMed, Google Scholar, Scopus, and Ovid, to identify literature and studies that discuss Ox-LDL and their involvement in the pathogenesis of atherosclerosis and cardiovascular diseases, thereby establishing a well-defined perspective on the subject. This review will provide a closer look at the Ox-LDL particle, the different forms and stages of oxidation, and the role of various LDL receptors involved in LDL uptake and breakdown focusing on how they contribute to atherosclerosis. Then, it will discuss the role of scavenger receptors and their contribution to the uptake of Ox-LDL and how this contributes to the development of atherosclerosis.

We present the case of a woman admitted for an acute ST-segment elevation myocardial infarction. Emergency catheterization was conducted, revealing diffuse lesions affecting 70% of the anterior descending artery from the mid to the distal third but with ventriculography compatible with Takotsubo syndrome. Two magnetic resonances were performed 90 days apart, confirming the unusual coexistence of Takotsubo syndrome and transmural infarction in the same event.

Data on the use of mechanical circulatory support devices in pregnant women are limited. A 27-year-old woman at 27 weeks and 6 days of gestation was supported by three different mechanical circulatory support devices due to cardiogenic shock. She came into spontaneous labor, which was complicated by major hemorrhage at the cannulation site, fetal distress, and transverse position, requiring emergency cesarean section. The postpartum period was complicated by intra-abdominal bleeding and arterial occlusion of lower extremity. When using mechanical circulatory support devices in pregnant women, a multidisciplinary approach is recommended.

Cardiovascular diseases, particularly ischemic heart disease (IHD), are the leading cause of mortality globally, accounting for 16% of deaths. Effective management of ischemic cardiomyopathy (ICM) is crucial, as outlined in the latest European Society of Cardiology (ESC) guidelines for chronic coronary syndrome (CCS). The guidelines emphasize a structured approach comprising four key steps: a general clinical evaluation to exclude non-cardiac causes, cardiac examination, and likelihood estimation using echocardiography, diagnostic testing such as stress echocardiography and coronary CT angiography, and treatment involving lifestyle changes and medication, alongside potential revascularization. The review underscores the importance of coronary angiography and functional assessments in diagnosing ischemic heart failure (IHF) and guiding treatment strategies. Non-invasive imaging techniques, including stress echocardiography and myocardial perfusion scintigraphy, are valuable for assessing ischemia and myocardial viability while reducing unnecessary invasive procedures. Coronary CT angiography is also examined for its procedural advantages and risks. A comparative analysis of diagnostic modalities highlights the strengths and limitations of each technique, emphasizing the need for individualized approaches based on patient characteristics. The ESC 2024 guidelines advocate for a patient-centered imaging strategy based on the likelihood of coronary artery disease (CAD) while addressing the economic and environmental impacts of imaging practices. Overall, implementing these guidelines and leveraging diverse imaging modalities can optimize management strategies for IHD, ultimately improving patient outcomes.

Papillary muscle rupture is a rare but fatal complication of acute myocardial infarction. The incidence of this complication has been reduced to less than 0.1% of patients due to the advent of primary percutaneous coronary intervention. Cardiogenic shock and acute pulmonary edema are the most common clinical presentations. In this review, we describe the role of transthoracic and transesophageal echocardiography in identifying the type, location, and hemodynamic consequences of the three different echocardiographic patterns of papillary muscle rupture. This information is crucial for managing medical therapy and determining the appropriate surgical or percutaneous treatment.
