Single-nucleotide polymorphisms in G protein subunits are linked to an increased risk of cardiovascular events among the general population. We assessed the effects of c.825C > T, -695/-694GC > TT, and c.393C > T polymorphisms on the risk of cardiovascular events among 454 patients undergoing renal replacement therapy. The patients were followed up for a median of 4.5 years after the initiation of dialysis. Carriers of the TT/TT genotype of required stenting because of coronary artery stenosis ( = 0.0009) and developed cardiovascular events involving more than one organ system ( = 0.03) significantly earlier and more frequently than did the GC/TT or GC/GC genotypes. Multivariate analysis found that the TT/TT genotype of was an independent risk factor for coronary artery stenosis requiring stent (hazard ratio, 4.5; = 0.001), cardiovascular events (hazard ratio, 1.93; = 0.04) and cardiovascular events affecting multiple organs (hazard ratio, 4.9; = 0.03). In the subgroup of male patients left ventricular dilatation with abnormally increased LVEDD values occurred significantly more frequently in TT genotypes of than in CT/CC genotypes ( = 0.007). Our findings suggest that male dialysis patients carrying the TT genotype of are at higher risk of left ventricular dilatation and that dialysis patients carrying the TT/TT genotype of are prone to coronary artery stenosis and severe cardiovascular events.

Background: Abelacimab is a fully human monoclonal antibody that binds to the inactive form of factor XI and blocks its activation. The safety of abelacimab as compared with a direct oral anticoagulant in patients with atrial fibrillation is unknown.
Methods: Patients with atrial fibrillation and a moderate-to-high risk of stroke were randomly assigned, in a 1:1:1 ratio, to receive subcutaneous injection of abelacimab (150 mg or 90 mg once monthly) administered in a blinded fashion or oral rivaroxaban (20 mg once daily) administered in an open-label fashion.

Indocyanine green (ICG) is a water-soluble green substance that is detectable through infrared cameras and emits greenish light. Approved for medical use in the 1950s, ICG has gained prominence as a real-time visualization tool. Widely recognized as a generally safe substance, ICG is applied in diverse fields.

Background: Cardiac surgery can lead to dysregulation with a pro-inflammatory state, resulting in adverse outcomes. Hemadsorption using the AN69 membrane (Oxiris membrane) has the properties to chelate inflammatory cytokines. We hypothesized that in patients at high risk of inflammation, the use of the Oxiris membrane could decrease inflammation, preserve endothelial function, and improve postoperative outcomes.

Background: ST-segment elevation myocardial infarction (STEMI) is a common and severe form of acute myocardial infarction (AMI).
Objectives: The study aimed to investigate the relationship between serum nitric oxide (NO) and endothelin-1 (ET-1) levels with the severity of STEMI and their predictive value for major adverse cardiovascular events (MACE) within one year after percutaneous coronary intervention (PCI) in STEMI patients.
Methods: The retrospective study was conducted on 269 STEMI patients who underwent PCI.

Extracorporeal perfusion systems utilized in open-heart surgeries with cardiopulmonary bypass can affect multiple body systems. The primary adverse effects of Extracorporeal Perfusion Systems (EPS) on the hematological system include postoperative bleeding and coagulation issues. The aim of this study is to evaluate the effects of on-pump time and cross-clamp duration on total platelet count (PLT) and platelet indices in open-heart surgeries performed using cardiopulmonary bypass.
