The role of lipoprotein(a) in atrial fibrillation: a systematic review.

Introduction: Atrial fibrillation (AF) is the most prevalent form of cardiac arrhythmia worldwide. Early diagnosis and treatment are essential, emphasizing the need to develop novel biomarkers. Lipoprotein(a) [Lp(a)] has recently been widely investigated as a potential risk factor for various cardiovascular conditions, including AF.

Association between standardized management algorithm and outcomes of patients undergoing high-risk percutaneous coronary interventions in the IMPELLA-PL registry.

Introduction: Impella CP is a percutaneous left ventricle assist device used in selected patients undergoing high-risk percutaneous coronary interventions (HR-PCI). To improve outcomes after Impella-supported HR-PCI, institutional Impella programs have been developed.

Objectives: We evaluated the association between the standardized periprocedural management algorithm and outcomes of patients undergoing HR-PCI in the national IMPELLA-PL Registry.

Endothelial Cell-Derived Extracellular Vesicles Allow to Differentiate Between Various Endotypes of INOCA: A Multicentre, Prospective, Cohort Study.

Ischemia and non-obstructive coronary artery disease (INOCA) might be due to coronary microvascular dysfunction (CMD), vasospastic angina (VSA) or both. We compared plasma concentration of various extracellular vesicles (EVs) in patients with different INOCA endotypes. Patients were divided into those with INOCA (CMD, VSA, mixed CMD + VSA) and non-anginal chest pain.

Cardiovascular risks and endothelial dysfunction in reproductive-age women with endometriosis.

Endometriosis is a prevalent gynecological condition, affecting around 10% of reproductive-age women. Inflammatory processes associated with endometriosis may contribute to endothelial dysfunction. Increased skin accumulation of advanced glycation end-products (AGEs), reflecting arterial stiffness, potentially links endometriosis with elevated risk of cardiovascular events.

Leukocyte Extracellular Vesicles Predict Progression of Systolic Dysfunction in Heart Failure with Mildly Reduced Ejection Fraction (LYCHEE) - A Prospective, Multicentre Cohort Study.

Risk stratification in heart failure with mildly-reduced ejection fraction (HFmrEF) remains challenging. We evaluated the predictive value of advanced glycation end products (AGEs) and plasma concentrations of extracellular vesicles (EVs) for the systolic and diastolic dysfunction progression in HFmrEF patients. Skin AGE accumulation was measured using AGE Reader.

Metabolic dysfunction-associated steatotic liver disease - A new indication for sodium-glucose Co-transporter-2 inhibitors.

Metabolic dysfunction-associated steatotic liver disease (MASLD) has been proposed as a new name for the previous non-alcoholic fatty liver disease (NAFLD). There are some differences between MASLD and NAFLD, e.g.

Same-day discharge coronary interventions: How to succeed?

Percutaneous coronary interventions (PCI) are the cornerstone of treatment in patients with coronary artery disease, generating substantial costs for the healthcare system. Considerable improvements in PCI technique, stent technology, and antiplatelet therapy led to a complication rate of <5%, a success rate of >95%, and lack of routine cardiothoracic surgical support. Thereby, the concept of same-day discharge following PCI has been proposed due to comparable efficacy, safety, and socioeconomic benefits of inpatient PCI.

Clot lysis time and thrombin generation in patients undergoing transcatheter aortic valve implantation.

Background: Aortic valve stenosis (AS) is the most prevalent valvular heart disease and is associated with a significant increase in mortality. AS has been shown to be linked with numerous coagulation system abnormalities, including increased fibrin deposition on the stenotic aortic valves. Transcatheter aortic valve implantation (TAVI) is the primary treatment method for patients at high surgical risk.

Heterogeneous and overlapping mechanisms of ischemia and nonobstructive coronary arteries: in-hospital results of the MOSAIC-COR registry.

Introduction: Ischemia and nonobstructive coronary arteries (INOCA) remains a significant clinical issue. Recent guidelines underscore the importance of comprehensive coronary physiology assessment to make specific diagnoses and implement tailored treatment strategies.

Objectives: Our primary objective was to implement comprehensive invasive diagnostics.

Extracellular Vesicles to Predict Outcomes After Transcatheter Aortic Valve Implantation - a Prospective, Multicenter Cohort Study.

Introduction: Transcatheter aortic valve implantation (TAVI) is an established treatment for aortic stenosis (AS) in patients at intermediate and high surgical risk. Circulating extracellular vesicles (EVs) are nanoparticles involved in cardiovascular diseases. We aimed to (i) determine the effect of TAVI on plasma concentrations of five EV subtypes and (ii) evaluate the predictive value of EVs for post-TAVI outcomes.

Ticagrelor downregulates the expression of proatherogenic and proinflammatory miR125-b compared to clopidogrel: A randomized, controlled trial.

Background: Platelet P2Y12 antagonist ticagrelor reduces cardiovascular mortality after acute myocardial infarction (AMI) compared to clopidogrel, but the underlying mechanism is unknown. Because activated platelets release proatherogenic and proinflammatory microRNAs, including miR-125a, miR-125b and miR-223, we hypothesized that the expression of these miRNAs is lower on ticagrelor, compared to clopidogrel.

Objectives: We compared miR-125a, miR-125b and miR-223 expression in plasma of patients after AMI treated with ticagrelor or clopidogrel.

N-terminal prohormone of brain natriuretic peptide in gestational hypertension and preeclampsia - State of the art.

N-terminal prohormone of brain natriuretic peptide (NT-proBNP) is a non-active prohormone secreted by ventricular cardiomyocytes into the circulation in response to ventricle overload, mainly due to increased blood volume. The changes in NT-proBNP levels during pregnancy have been investigated in multiple studies. In the case of hypertensive disorders of pregnancy, increased vasoconstriction leads to increased blood pressure and afterload.

Lipoprotein apheresis affects the concentration of extracellular vesicles in patients with elevated lipoprotein (a).

Lipoprotein apheresis (LA) is a therapeutic option for hyperlipoproteinemia(a) (hyper-Lp(a)) and atherosclerotic cardiovascular disease (ASCVD). LA improves blood rheology, reduces oxidative stress parameters and improves endothelial function. The underlying molecular mechanisms of LA beneficial effects are unknown, but it has been suggested that LA exhibits multiple activities beyond simply removing lipoproteins.

MicroRNAs in extracellular vesicles released from epicardial adipose tissue promote arrhythmogenic conduction slowing.

Background: Patients with excess epicardial adipose tissue (EAT) are at increased risk of developing cardiac arrhythmias. EAT promotes arrhythmias by depolarizing the resting membrane of cardiomyocytes, which slows down conduction and facilitates re-entrant arrhythmias. We hypothesized that EAT slows conduction by secreting extracellular vesicles (EVs) and their microRNA (miRNA) cargo.

The Ketogenic Effect of SGLT-2 Inhibitors-Beneficial or Harmful?

Sodium-glucose cotransporter-2 (SGLT-2) inhibitors, also called gliflozins or flozins, are a class of drugs that have been increasingly used in the management of type 2 diabetes mellitus (T2DM) due to their glucose-lowering, cardiovascular (CV), and renal positive effects. However, recent studies suggest that SGLT-2 inhibitors might also have a ketogenic effect, increasing ketone body production. While this can be beneficial for some patients, it may also result in several potential unfavorable effects, such as decreased bone mineral density, infections, and ketoacidosis, among others.
