New results from a vast Mayo Clinic meta-analysis suggest that combining ezetimibe with statins to lower LDL-C could have significant mortality and MACE benefits over statin monotherapy. Statins are one of the most prescribed drugs in the U.S., with over 25% of all adults 40 and up taking them. However, not everyone with high cholesterol benefits from statins, leading many drug developers to focus on novel ways to lower LDL-C levels.

ST-elevation myocardial infarction (STEMI) is a critical cardiovascular emergency characterized by acute coronary artery occlusion and subsequent myocardial injury. The current standard of care is primary percutaneous coronary intervention (PPCI), which aims to rapidly restore epicardial blood flow. However, despite successful revascularization, microvascular obstruction (MVO) remains a major challenge, contributing to adverse clinical outcomes.
Background Heart failure with preserved ejection fraction is a recognised outcome in patients with myocardial infarction, although heart failure with reduced ejection fraction is more common. Identifying early indicators specific to heart failure with preserved ejection fraction in patients with myocardial infarction could support targeted preventive strategies.
Background High-sensitivity cardiac troponin tests have enhanced early myocardial infarction diagnosis, yet many patients still land in the observe zone (OZ). Guidelines suggest a 3-hour troponin measurement for those in the European Society of Cardiology (ESC) 0/1 hour-algorithm’s OZ, but evidence on extended troponin testing times and their impact on diagnostic accuracy and outcomes remains sparse.

Perseverance, hard work, integrity and commitment can transform aspiration into reality.
BackgroundThere is a growing body of evidence indicating that metabolites are associated with an increased risk of cardiovascular diseases (CVDs), the underlying causality of these associations remains largely unchallenged. Given the inherent difficulty in establishing causality using epidemiological data, we employed the technique of Mendelian randomization to investigate the potential role of plasma metabolite factors in influencing the risk of CVDs.MethodsThe exposure was based on 1,400 plasm
Heart failure (HF) is a complex syndrome which leads to significant morbidity and mortality, poor quality of life and extremely high costs to healthcare systems worldwide. Although progress in the management of HF in high-income countries is leading to an overall reduction in the incidence and mortality of HF, there is a starkly different scenario in low- and middle-income countries (LMICs).
Background Heart failure with preserved ejection fraction (HFpEF) is a complex clinical syndrome in which signs and symptoms of heart failure (HF) occur despite a normal left ventricular ejection fraction. Transthoracic echocardiography (TTE) is the first-line imaging modality but disparities in patient pathways across the UK can lead to delayed diagnosis and treatment.
Experts discuss the long-term efficacy and safety of abrocitinib and upadacitinib in atopic dermatitis (AD), with sustained monotherapy results showing significant improvements in Investigator Global Assessment (IGA), Eczema Area and Severity Index (EASI), and Validated IGA-AD (vIGA-AD) scores. They also consider the safety profiles and potential risks, particularly in older patients, for long-term use of JAK inhibitors.
Observational studies and randomised controlled trials (RCTs) have yielded conflicting results regarding the outcomes of multiple arterial grafts (MAG) vs. single arterial grafts (SAG) in coronary artery bypass graft (CABG) surgery. We conducted a comprehensive search across multiple databases for RCTs that directly compared MAG and SAG. The clinical outcomes assessed included all-cause mortality, cardiac-specific mortality, myocardial infarction (MI), repeat revascularization, stroke, sternal w
tim.hodson Thu, 03/27/2025 - 12:18 March 27, 2025 Abbott recently announced it has received CE Mark in Europe for the Volt PFA System to treat patients battling atrial fibrillation (AFib). With the earlier-than-expected CE Mark, Abbott has begun commercial PFA cases in the EU with physicians who have already gained experience with the Volt PFA System within Abbott's PFA clinical studies.
Background Mechanical stress on the heart is commonly considered the sole stimulus explaining the synthesis and release of circulating natriuretic peptides and their derivatives. While one of the most critical paradigms in cardiology is that mechanical load increases oxygen consumption, clinical studies on these peptides have neglected the relationship between mechanical stress and oxygen metabolism.
Advances in molecular genetics during the past decades led to seminal discoveries in the genetic basis of cardiovascular diseases, resulting in a new understanding of their pathogenesis, determinants of natural history and more recently paved the way for innovative therapies. A significant gap, however, exists between the rapidly increasing knowledge, especially of cardiovascular Mendelian disorders, and the medical applications in daily practice.
IntroductionVentricular septal defect (VSD) is a common congenital heart disease (CHD), accounting for 2030% of all CHD cases. While surgical closure has been the gold standard for treatment, transcatheter closure has emerged as a less invasive alternative, particularly for perimembranous VSDs. This study aimed to evaluate the early and mid-term outcomes of transcatheter closure using a double-disc occluder device in a single-center Vietnamese cohort.MethodA prospective descriptive study was con
Panelists discuss how Bruton tyrosine kinase (BTK) inhibitors represent a promising new therapeutic class for chronic spontaneous urticaria (CSU) by offering rapid symptom control through targeted inhibition of both mast cell and B cell pathways, with newer agents like remibrutinib showing high selectivity, favorable safety, and robust efficacy in clinical trials that could position them as an important oral therapy option between antihistamines and biologics.
Introduction Atrial fibrillation is the most prevalent sustained arrhythmia worldwide and is expected to increase substantially within the coming years. Although lifestyle changes and risk factor modification are now acknowledged as central components of atrial fibrillation management, the effects of exercise on disease-specific outcomes are still not extensively documented due to few high-quality randomised trials.
Pericardial complications are very common following cardiac surgery. It is estimated that up to 30–40% of patients may develop a postpericardiotomy syndrome (PPS) and >50–60% of patients show pericardial effusions after cardiac surgery. 1 2 Pericardial complications may range from asymptomatic pericardial and/or pleural effusion to cardiac tamponade, and may include PPS, and postoperative atrial fibrillation (POAF), triggered by pericarditis in predisposed individuals. 3 All thes
