The COVID-19 pandemic had a significant impact on both the incidence of acute cerebral circulatory disorders and the structure of mortality. SARS-CoV-2 increases the risk of both ischemic and hemorrhagic stroke. The key pathogenetic links underlying the development of cerebral stroke in COVID-19 are impaired functioning of angiotensin 2 receptors, accompanied by the accumulation of excess angiotensin 2, endothelial dysfunction, hypercoagulation, hyperproduction of proinflammatory cytokines and oxidative storm. In patients with stroke and COVID-19, the severity of the lesion is associated with a dual mechanism of ischemia - systemic and cerebral. The possibilities of medical correction of systemic disorders associated with coronavirus infection, as well as local ones caused by ischemic or hemorrhagic brain damage, are limited. Substances with antioxidant activity could potentially be effective in patients with stroke and COVID-1.

Respiratory tract infections (RTIs) caused by bacteria or viruses are associated with stroke severity. Recent studies have revealed an imbalance in the von Willebrand factor (VWF)-ADAMTS13 axis in patients with RTIs, including COVID-19. We examined whether this imbalance contributes to RTI-mediated stroke severity.

Background And Objectives: Methylenetetrahydrofolate reductase (MTHFR) is a key enzyme that regulates folate and homocysteine metabolism. Genetic variation in has been implicated in cerebrovascular disease risk, although research in diverse populations is lacking. We thus aimed to investigate the effect of genetically predicted MTHFR activity on risk of ischemic stroke (IS) and its main subtypes using a multiancestry Mendelian randomization (MR) approach.

The recently introduced concept of 'exposome' emphasizes the impact of non-traditional threats onto cardiovascular health. Among these, air pollutants - particularly fine particulate matter < 2.5 μm (PM2.

Background: Chronic kidney disease (CKD) is associated with higher risk of myocardial infarction and anemia. Among patients with anemia and CKD who experience myocardial infarction, it remains uncertain if a liberal red blood cell transfusion threshold strategy (hemoglobin cutoff [Hgb] < 10 g/dL) is superior to a restrictive transfusion threshold (Hgb 7-8 g/dL) strategy.
Methods: Among the 3,504 patients enrolled in the Myocardial Ischemia and Transfusion (MINT) trial with non-missing creatinine, we compared baseline characteristics and 30-day and 6-month outcomes of patients without CKD (N = 1279), CKD with eGFR 30-60 mL/min/1.

Background: Ventricular tachycardia (VT) in patients with cardiac sarcoidosis (CS) can lead to sudden cardiac death. The role of ventricular tachycardia ablation (VTA) in CS has been investigated in a few small, single-center, and larger observational studies, but the evidence still needs to be provided. This study aimed to investigate the clinical outcomes of VTA in patients with CS admitted with a diagnosis of VT.
