    Background: Hypercoagulopathy in coronavirus disease MESHD 2019 (COVID-19) causing deep vein thrombosis MESHD and pulmonary artery embolism MESHD necessitate systemic anticoagulation. Case reports of intracerebral hemorrhages MESHD in ventilated COVID-19 patients warrant precaution. It is unclear however, if COVID-19 patients with acute respiratory distress HP syndrome MESHD (ARDS) with and without extracorporeal membrane oxygenation therapy (ECMO) have more intracerebral hemorrhages MESHD (ICH) compared to other ARDS patients.Methods: We conducted a retrospective observational single center study enrolling all patients with ARDS from 01/2018-05/2020. Patients with ARDS positive for SARS-CoV2 PCR were allocated to the COVID-19 group. Propensity score matching was performed for age TRANS, ECMO and risk of bleeding according to HAS-BLED score.Results: A total of 163, mostly severe ARDS patients were identified, 116 (71.2%) without COVID-19 and 47 (28.8%) positive for SARS-CoV-2. The two groups were comparable concerning the main confounders of ICH including age TRANS, HAS-BLED score, need for ECMO-therapy as well as anticoagulation levels reported. In 63/163 cases (38.7%), veno-venous ECMO therapy was required and ICU survival was 52.8%. Although HAS-BLED-score on admission was generally low (1.6±1.3), intracerebral hemorrhage MESHD was detected in 22 patients (13.5%) with no statistical difference between the groups (11.2 vs. 19.1% with and without SARS-CoV-2, respectively, p=0.21). Propensity score matching confirmed similar intracerebral bleeding rates in both groups (12.8 vs. 19.1% with and without SARS-CoV-2, respectively, p=0.57). Conclusions: Intracerebral hemorrhage MESHD was detectable in every tenth patient with ARDS. We found no statistically significant increased bleeding rate in patients with ARDS due to COVID-19 compared to other causes of ARDS.

    Covid-19 disease MESHD is caused by SARS Cov-2 virus. Despite its high transmissibility TRANS, the CFR (Case Fatality Rate) of COVID-19 seems to be lower than the SARS (9,5%) and MERS (34,4%) ones93 , but higher than the influenza one (0-1%)94,95 . The disease is asymptomatic MESHD asymptomatic TRANS or paucisymptomatic in most of the patients, although in few cases it can be characterized by serious complications. The main causes of hospitalization in intensive care are represented by ALI ( Acute Lung Injury MESHD), ARDS (Acute Respiratory Distress HP Syndrome MESHD), cardiovascular problems and coagulopathies (diffuse thrombosis MESHD, microthrombosis, embolisms MESHD, myocarditis MESHD myocarditis HP, arrhytmias, heart failure MESHD, stroke MESHD stroke HP)96-98, acute nephropathy99,100 and encephalopathies101. The virus presence in the vascular wall can cause endotheliitis, which triggers the process of diffuse coagulation that can lead to a worsening of the systemic inflammation MESHD. The exaggerated inflammatory response seems to be connected with the development of ARDS, MOF ( Multiple Organ Failure MESHD) and coagulopathies102-107.

    Objective: To describe the ischemic stroke HP stroke MESHD etiopathogenesis related to COVID-19 in a cohort of NYC hospitals. Background: Extra-pulmonary involvement of COVID-19 has been reported in the hepatic, renal and hematological systems. Most neurological manifestations are non-focal but few have reported the characteristics of ischemic strokes HP strokes MESHD or investigated its pathophysiology. Methods: Over the last 6 weeks, data from four centers in New York City were collected to review the possible ischemic stroke HP stroke MESHD types seen in COVID-19 positive patients. Their presentation, demographics, other related vascular risk factors, associated laboratory and coagulation markers, as well as imaging and outcomes were collected. Results: In our study, age TRANS range of patients was 25-75 with no significant male TRANS preponderance. 70% presented for acute hospitalization due the stroke MESHD stroke HP. About a fifth did not have common risk factors for ischemic stroke HP stroke MESHD like diabetes and hypertension MESHD hypertension HP. None had history of atrial fibrillation MESHD atrial fibrillation HP or smoking. 50% had poor outcome with four ending in mortality and one in a critical condition due ARDS. All had high Neutrophil/Lymphocyte ratio except one who demonstrated some neurological recovery. In 70% of our cases, D-dimer levels were collected, and all showed mild to severe elevation. None of the emergent large vessel occlusion (LVO) cases had known cardiac risk factors but two out of five were found to have cardiac abnormalities during the course of their hospitalization. All LVOs had hypercoagulable lab markers especially elevated D-dimer and/or Fibrinogen. The LVO patients were younger and sicker with a median age TRANS of 46 and mean NIHSS of 24 as opposed to non-LVOs with a median age TRANS of 62 and mean NIHSS of 6 respectively. Conclusion: COVID-19 related ischemic events can be small vessel, branch emboli or large vessel occlusions. The latter is often associated with either a hypercoagulable state or cardio- embolism MESHD. Patient outcomes were worse when multi-organ or pulmonary system failure prevailed.
