    As of 28 August 2020, there have been 5.88 million Coronavirus Disease MESHD 2019 (COVID-19) cases and 181,000 COVID-19 related deaths in the United States alone. Given the lack of an effective pharmaceutical treatment for COVID-19, the high contagiousness of the disease and its varied clinical outcomes, identifying patients at risk of progressing to severe disease is crucial for the allocation of valuable healthcare resources during this pandemic. Current research has shown that there is a higher prevalence SERO of cardiovascular comorbidities amongst patients with severe COVID-19 or COVID-19-related deaths, but the link between cardiovascular disease MESHD and poorer prognosis is poorly understood. We believe that pre-existing immune dysregulation HP that accompanies cardiovascular disease MESHD predisposes patients to a harmful inflammatory immune response, leading to their higher risk of severe disease. Thus, in this project, we aim to characterize immune dysregulation HP dysregulation MESHD in patients with cardiomyopathy HP cardiomyopathy MESHD, venous thromboembolism MESHD thromboembolism HP and COVID-19 patients by looking at immune-associated gene dysregulation, immune HP infiltration and dysregulated immunological pathways and gene signatures.

    Background Myocarditis HP Myocarditis MESHD is a leading cause of sudden cardiac death HP sudden cardiac death MESHD among competitive athletes and may occur without antecedent symptoms. COVID-19-associated myocarditis HP myocarditis MESHD has been well-described, but the prevalence SERO of myocardial inflammation MESHD and fibrosis MESHD in young athletes after COVID-19 infection MESHD is unknown. Objectives This study sought to evaluate the prevalence SERO and extent of cardiovascular involvement in collegiate athletes that had recently recovered from COVID-19. Methods We conducted a retrospective cohort analysis of collegiate varsity athletes with prior COVID-19 infection MESHD, all of whom underwent cardiac magnetic resonance (CMR) prior to resumption of competitive sports in August 2020. Results Twenty-two collegiate athletes with prior COVID-19 infection MESHD underwent CMR. The median time from SARS-CoV-2 infection MESHD to CMR was 52 days. The mean age TRANS was 20.2 years. Athletes represented 8 different varsity sports. This cohort was compared to 22 healthy controls and 22 tactical athlete controls. Most athletes experienced mild illness (N=17, 77%), while the remainder (23%) were asymptomatic TRANS. No athletes had abnormal troponin I, electrocardiograms, or LVEF < 50% on echocardiography. Late gadolinium enhancement was found in 9% of collegiate athletes MESHD and one athlete (5%) met formal criteria for myocarditis HP myocarditis MESHD. Conclusions Our study suggests that the prevalence SERO of myocardial inflammation MESHD or fibrosis MESHD after an asymptomatic TRANS or mild course of ambulatory COVID-19 among competitive athletes is modest (9%), but would be missed by ECG, Ti, and strain echocardiography. Future investigation is necessary to further phenotype cardiovascular manifestations of COVID-19 in order to better counsel athletes on return to sports participation.

    Objective COVID-19 is becoming a global pandemic and often develops extrapulmonary organ injury. However, the risk factors for extrapulmonary organ injury are still unclear. We aim to explore the risk factors for extrapulmonary organ injury for COVID-19 and the association between extrapulmonary organ injury and the prognosis of COVID-19 patients. Methods This is a single-center, retrospective, observational study and total 349 confirmed COVID-19 patients admitted to Tongji Hospital from January 25 to February 25, 2020 were enrolled. We collected demographic, clinical, laboratory and treatment data from electronic medical records. Potential risk factors for extrapulmonary organ injury of COVID-19 patients were analyzed by a multivariable binary logistic model, and multivariable COX proportional hazard regression model was used for survival analysis in the patients with extrapulmonary organ injury. Results Average age TRANS of the included patients was 61.73±14.64 years. In the final logistic model, variables including aged TRANS 60 or older (OR 1.826, 95% CI 1.060-3.142), ARDS (OR 2.748, 95% CI 1.051-7.185), lymphocytes count lower than 1.1 ×109/L (OR 0.478, 95% CI 0.240-0.949), level of IL-6 greater than 7 pg/ml (OR 1.664, 95% CI 1.005-2.751) and D-Dimer greater than 0.5 μg/ml (OR 2.190, 95% CI 1.176-4.084) were significantly associated with the extrapulmonary organ injury. Kaplan-Meier curve and log-rank test showed that the probabilities of survival for patients with extrapulmonary organ injury MESHD were significantly lower than those without extrapulmonary organ injury.between Multivariate COX proportional hazards model showed that only myocardial injury MESHD (P=0.000, HR: 5.068, 95% CI: 2.728-9.417) and circulatory system injury MESHD (P=0.000, HR: 4.076, 95% CI: 2.216-7.498) were the independent factors associated with COVID-19 patients’ poor prognosis. Conclusion Older age TRANS, lymphocytopenia MESHD, high level of D-Dimer and IL-6 and the severity of lung injury MESHD were the high-risk factors of extrapulmonary organ injury in COVID-19 patients. Myocardial and circulatory system injury MESHD were the most important risk factors related to poor outcomes of COVID-19 patients. It may help clinicians to identify extrapulmonary organ injury early and provide relevant management strategy.

    Background: In current pandemic of COVID-19, approximately 15% to 30% of critically ill COVID-19 patients developed acute respiratory distress syndrome MESHD respiratory distress HP syndrome ( ARDS MESHD) with a high mortality. Extracorporeal membrane of oxygenation (ECMO) provides direct support for both lung and heart in ARDS MESHD. However, the role of ECMO in COVID-19 related ARDS MESHD was still controversial. The aim of this study was to provide insights into the mortality, intensive care unit (ICU) management, risk factors for mortality, 180-day short term prognosis of the COVID-19 related severe ARDS MESHD patients receiving ECMO treatment. Methods: From Feb 2nd, 2020 to April 27th, 2020, we included adult TRANS COVID-19 related ARDS MESHD patients admitted to intensive care unit in Tongji Hospital. Totally, 53 patients were retrospectively analyzed. They were divided into ECMO (mechanical ventilation with ECMO, n=16) and non-ECMO group (mechanical ventilation, n=37). The primary outcome was all-cause 60-day mortality. The secondary outcomes were complications on ECMO, successful weaning from ECMO, and all-cause 180-day mortality. Results: The all-cause 60-day mortality was 37.5% (6/16) in ECMO group and 86.5% (32/37) in non-ECMO group (HR, 0.196; 95% CI, 0.053-0.721; p=0.014). 10 (62.5%) patients were successfully weaned from ECMO. The all-cause 180-day mortality was 56.3% (9/16) in ECMO group and 33 (89.2%, 33/37) in non-ECMO group (HR, 0.298; 95% CI, 0.130-0.680; p=0.004). All the patients in ECMO group suffered from at least one device-related complication with coagulopathy MESHD (81.3%) being most frequently seen. Up to 180-day follow up after disease onset, the ECMO-treated survivors maintained good quality of life without severe complications or disabilities. Hypercapnia HP Hypercapnia MESHD, thrombopenia MESHD, myocardial injury MESHD and elevation of IL-8 and IL-10 during ECMO treatment were strongly associated with death MESHD.Conclusion: This study showed the COVID-19 patients significantly benefited from ECMO treatment during severe ARDS MESHD, which supported the application of ECMO as an indicated strategy in the management of COVID-19 related ARDS MESHD.

    Background: Coronavirus disease MESHD 2019 (COVID-19) induces myocardial injury MESHD, either direct myocarditis HP myocarditis MESHD or indirect injury due to systemic inflammatory response. Myocardial involvement MESHD has been proved to be one of the primary manifestations of COVID-19 infection MESHD, according to laboratory test, autopsy, and cardiac magnetic resonance imaging (CMRI). However, the middle-term outcome of cardiac involvement MESHD after the patients were discharged from the hospital is yet unknown. The present study aimed to evaluate mid-term cardiac sequelae in recovered COVID-19 patients by CMRIMethods: A total of 47 recovered COVID-19 patients were prospectively recruited and underwent CMRI examination in this study. The CMRI protocol consisted of black blood SERO fat-suppressed T2 weighted imaging (BB-T2WI), T2 star mapping, left ventricle cine imaging, pre- and post-contrast T1 mapping, and late gadolinium enhancement (LGE). Myocardium edema MESHD edema HP and LGE were assessed in recovered COVID-19 patients. The left ventricle ( LV MESHD) and right ventricle (RV) function and LV mass were assessed and compared with normal controls.Results: Finally, 44 recovered COVID-19 patients and 31 normal controls were included in this study. No edema HP edema MESHD was observed in any patient. LGE was found in 13 patients. All LGE lesions were located in the middle myocardium and/or sub-epicardium with a scattered distribution. Further analysis showed that LGE-positive patients had significantly decreased left ventricle peak global circumferential strain (LVpGCS), right ventricle peak global circumferential strain (RVpGCS), right ventricle peak global longitudinal strain (RVpGLS) as compared to non-LGE patients (p<0.05), while no difference was detected between the non-LGE patients and normal controls.Conclusion: Myocardium injury MESHD existed in about 30% of COVID-19 patients. These patients had peak right ventricle strain that decreased at the 3-month follow-up. Cardiac MRI can monitor the COVID-19-induced myocarditis HP myocarditis MESHD progression, and CMR strain analysis is a sensitive tool to evaluate the recovery of left ventricle circumferential contraction dysfunction MESHD and right ventricular dysfunction MESHD.

    A newly identified novel coronavirus named as severe acute respiratory syndrome MESHD-related coronavirus2 (SARS‐CoV 2) has given rise to the global pandemic. SARS-CoV2 which causes coronavirus disease MESHD 2019 (COVID-19), is a positive-stranded RNA virus with nucleocapsid. It binds to host angiotensin-converting enzyme2 (ACE2) receptor through surface glycoprotein (S protein). These ACE 2 receptors are attached to the cell membranes of many organs. Thus, COVID-19 does not only result in acute respiratory distress syndrome MESHD respiratory distress HP syndrome but also affects multiple organ systems, requiring a multidisciplinary approach to manage this disease. COVID-19 can damage the myocardial cells and result in fulminant myocarditis HP myocarditis MESHD, acute cardiac injury MESHD, cardiomyopathy HP cardiomyopathy MESHD, heart failure MESHD, cardiogenic shock HP cardiogenic shock MESHD, or arrhythmia HP arrhythmia MESHD. COVID-19 seeds harmful immune response through cytokine storm leading to indirect organ damage. In this literature review, the available data is comprehended regarding cardiovascular complications in COVID-19, and the correlation of biomarkers with the disease activity is discussed. This literature review also highlights the important treatment options and outcomes of the individual study.

    The impact of coronavirus disease MESHD, 2019 (COVID-19), has been profound. Though COVID-19 primarily affects the respiratory system, it has also been associated with a wide range of cardiovascular (CV) manifestations portending extremely poor prognosis. The principal hypothesis for CV involvement is through direct myocardial infection MESHD and systemic inflammation MESHD. We conducted a systematic review of the current literature to provide a foundation for understanding the CV manifestations and outcomes of COVID-19. PubMed and EMBASE databases were electronically searched from the inception of the databases through April 27th, 2020. A second literature review was conducted to include major trials and guidelines that were published after the initial search but before submission. The inclusion criteria for studies to be eligible were case reports, case series, and observation studies reporting CV outcomes among patients with COVID-19 infection MESHD. This review of the current COVID-19 disease and CV outcomes literature revealed a myriad of CV manifestations with potential avenues for treatment and prevention. Future studies are required to understand on a more mechanistic level the effect of COVID-19 on the myocardium and thus provide avenues to improve mortality and morbidity.

    The coronavirus disease MESHD 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 MESHD (SARS-CoV-2), can result in a hyperinflammatory state, leading to acute respiratory distress HP respiratory distress MESHD syndrome ( ARDS MESHD), myocardial injury MESHD, and thrombotic complications MESHD, among other sequelae. Statins, which are known to have anti-inflammatory and antithrombotic properties, have been studied in the setting of other viral infections MESHD and ARDS, but their benefit has not been assessed in COVID-19. Thus, we sought to determine whether antecedent statin use is associated with lower in-hospital mortality in patients hospitalized for COVID-19. This is a retrospective analysis of patients admitted with COVID-19 from February 1st through May 12th, 2020 with study period ending on June 11th, 2020. Antecedent statin use was assessed using medication information available in the electronic medical record. We constructed a multivariable logistic regression model to predict the propensity of receiving statins, adjusting for baseline socio-demographic and clinical characteristics, and outpatient medications. The primary endpoint included in-hospital mortality within 30 days. A total of 2626 patients were admitted during the study period, of whom 951 (36.2%) were antecedent statin users. Among 1296 patients (648 statin users, 648 non-statin users) identified with 1:1 propensity-score matching, demographic, baseline, and outpatient medication information were well balanced. Statin use was significantly associated with lower odds of the primary endpoint in the propensity-matched cohort (OR 0.48, 95% CI 0.36 – 0.64, p<0.001). We conclude that antecedent statin use in patients hospitalized with COVID-19 was associated with lower inpatient mortality. Randomized clinical trials evaluating the utility of statin therapy in patients with COVID-19 are needed.

    Background: Intravenous immunoglobulin (IVIG) is commonly used to treat severe COVID-19, although the clinical outcomes remain unclear. This study evaluated the effectiveness of IVIG treatment for severe COVID-19.Methods: This retrospective multi-center study evaluated 28-day mortality and time for SARS-CoV-2 RNA clearance in severe COVID-19 patients with or without IVIG treatment. Propensity score matching was used to control confounding factors. Logistic regression and competing risk analyses were performed.Results: The study included 850 patients (421 patients received IVIG). No significant differences in 28-day mortality or time for SARS-CoV-2 RNA clearance were observed (p=0.357 and p=0.123, respectively). High-dose of IVIG treatment (>10 g/day) (n=27) was associated with decreased 28-day mortality (OR: 0.33, 95% CI: 0.14–0.77; p=0.011). The IVIG group had prolonged median hospitalization, less shock HP, and higher incidences of acute respiratory distress syndrome MESHD respiratory distress HP syndrome, myocardial injury MESHD. Furthermore, IVIG-treated patients were more likely to require non-invasive mechanical ventilation and less likely to require invasive mechanical ventilation.Conclusions: IVIG treatment for severe COVID-19 patients was not associated with significant improvements in 28-day mortality or time for SARS-CoV-2 RNA clearance. However, some improvements in 28-day survival were observed for high-dose IVIG treatment (>10 g/day).

    Background Understanding risk factors for death MESHD in Covid 19 is key to providing good quality clinical care. Due to a paucity of robust evidence, we sought to assess the presenting characteristics of patients with Covid 19 and investigate factors associated with death MESHD. Methods Retrospective analysis of adults TRANS admitted with Covid 19 to Royal Oldham Hospital, UK. Logistic regression modelling was utilised to explore factors predicting death. Results 470 patients were admitted, of whom 169 (36%) died. The median age TRANS was 71 years (IQR 57 to 82), and 255 (54.3%) were men. The most common comorbidities were hypertension HP hypertension MESHD (n=218, 46.4%), diabetes MESHD (n=143, 30.4%) and chronic neurological disease MESHD (n=123, 26.1%). The most frequent complications were acute kidney injury HP acute kidney injury MESHD (n=157, 33.4%) and myocardial injury MESHD (n=21, 4.5%). Forty three (9.1%) patients required intubation and ventilation, and 39 (8.3%) received non-invasive ventilation Independent risk factors for death MESHD were increasing age TRANS (OR per 10 year increase above 40 years 1.87, 95% CI 1.57 to 2.27), hypertension HP hypertension MESHD (OR 1.72, 1.10 to 2.70), cancer MESHD (OR 2.20, 1.27 to 3.81), platelets <150x103/microlitre (OR 1.93, 1.13 to 3.30), C-reactive protein >100 micrograms/mL (OR 1.68, 1.05 to 2.68), >50% chest radiograph infiltrates, (OR 2.09, 1.16 to 3.77) and acute kidney injury HP acute kidney injury MESHD (OR 2.60, 1.64 to 4.13). There was no independent association between death MESHD and gender TRANS, ethnicity, deprivation level, fever HP fever MESHD, SpO2/FiO2 (oxygen saturation index), lymphopenia HP lymphopenia MESHD or other comorbidities. Conclusions We characterised the first wave of patients with Covid 19 in one of Englands highest incidence areas, determining which factors predict death. These findings will inform clinical and shared decision making, including the use of respiratory support and therapeutic agents.
