    BACKGROUND Chloroquine is used for the treatment of COVID-19 patients. However, efficacy of the chloroquine has been under discussion. Variability of clinical outputs of the drug application requires implementation of a companion diagnostic that would allow monitoring responsiveness to chloroquine. The first line of such markers would be markers already used in clinics. Analysis of reported mechanisms of COVID-19 and chloroquine may lead to such markers.METHODS Systemic analysis of molecular mechanisms and markers engaged by chloroquine and COVID-19 virus was performed. The networks of regulatory mechanisms were explored for an intersection and relevance to clinical markers.RESULTS Reported here systemic analysis describes the intersection of molecular mechanisms of chloroquine and processes engaged by COVID-19. 266 nodes provide insight into the mechanisms of chloroquine impact on the infection MESHD and represent a pool of companion diagnostic markers. As an example, an intersection with the markers of heart arrhythmia MESHD arrhythmia HP retrieved 19 nodes. Thirteen of them were reported in human plasma SERO: levels of albumin, amyloid precursor protein, and endoglin correlate with adverse cardiac effects.CONCLUSIONS Reported nodes are the candidate markers for companion diagnostic of the chloroquine application to COVID-19 patients. Some of these markers are already used in the clinic and their interpretation may contribute to monitoring for adverse effects of chloroquine.

    Background: Hydroxychloroquine and Azithromycin use is associated with QT interval prolongation MESHD and arrhythmias HP arrhythmias MESHD. Despite ongoing multiple clinical trials for treatment of COVID19 infection MESHD, no definite cardiac safety protocols were proposed. The aim of our study was to assess cardiac safety in COVID-19 patients treated with the combination of Hydroxychloroquine and Azithromycin using close monitoring and arrhythmia HP arrhythmia MESHD risk management plan.Methods and results: We retrospectively examined arrhythmia HP arrhythmia MESHD safety of treatment with Hydroxychloroquine and Azithromycin in the setting of pre-defined cardiac arrhythmia MESHD arrhythmia HP risk management plan. 81 patients were included from March 23rd to May 10th 2020. The median age TRANS was 59 years, 58.0% were female TRANS. The majority of the study population (82.7%) had comorbidities, 98.8% had radiological signs of pneumonia HP pneumonia MESHD. 7 patients (8.6%) had QTc prolongation MESHD of ≥500 ms. The treatment was discontinued in 4 patients (4.9%). 14 patients (17.3%) experienced QTc≥480 ms and 16 patients (19.8%) had an increase of QTc≥60 ms. None of the patients developed ventricular tachycardia HP ventricular tachycardia MESHD. The risk factors significantly associated with QTc≥500 ms were hypokalemia HP hypokalemia MESHD (p = 0.032) and use of diuretics during the treatment (p = 0.020). Three patients had a lethal outcome; none of them associated with ventricular arrhythmias HP ventricular arrhythmias MESHD.Conclusion: We recorded a low incidence of QTc prolongation MESHD ≥500 ms and no ventricular tachycardia HP ventricular tachycardia MESHD events in COVID-19 patients treated with Hydroxychloroquine and Azithromycin using cardiac arrhythmia MESHD arrhythmia HP risk management plan.

    Background: Coronavirus disease 2019 (COVID-19) has been reported to cause worse outcomes in patients with underlying cardiovascular disease MESHD, especially in patients with acute cardiac injury MESHD, which is determined by elevated levels of high- sensitivity SERO troponin. There is a paucity of data on the impact of congestive heart failure HP congestive heart failure MESHD ( CHF MESHD) on outcomes in COVID-19 patients. Methods: We conducted a literature search of PubMed/Medline, EMBASE, and Google Scholar databases from 11/1/2019 till 06/07/2020, and identified all relevant studies reporting cardiovascular comorbidities, cardiac biomarkers, disease severity, and survival. Pooled data from the selected studies were used for metanalysis to identify the impact of risk factors and cardiac biomarker elevation on disease severity and/or mortality. Results: We collected pooled data on 5,967 COVID-19 patients from 20 individual studies. We found that both non-survivors and those with severe disease had an increased risk of acute cardiac injury MESHD and cardiac arrhythmias MESHD arrhythmias HP, our pooled relative risk (RR) was - 8.52 (95% CI 3.63-19.98) (p<0.001); and 3.61 (95% CI 2.03-6.43) (p=0.001), respectively. Mean difference in the levels of Troponin-I, CK-MB, and NT-proBNP was higher in deceased and severely infected MESHD patients. The RR of in-hospital mortality was 2.35 (95% CI 1.18-4.70) (p=0.022) and 1.52 (95% CI 1.12-2.05) (p=0.008) among patients who had pre-existing CHF MESHD and hypertension HP hypertension MESHD, respectively. Conclusion: Cardiac involvement in COVID-19 infection MESHD appears to significantly adversely impact patient prognosis and survival. Pre-existence of CHF MESHD and high cardiac biomarkers like NT-pro BNP and CK-MB levels in COVID-19 patients correlates with worse outcomes. Keywords: Acute cardiac injury MESHD; cardiac arrhythmia MESHD arrhythmia HP; mortality risk; cardiac biomarkers, COVID-19.

    Introduction: The 2019 novel coronavirus disease MESHD (COVID-19) is a current pandemic. Cardiovascular manifestations of COVID-19 have been described in many studies; however, no studies have examined the prevalence SERO and characterizations of cardiac arrhythmias MESHD arrhythmias HP among patients with COVID-19 infection MESHD. The aim of this meta-analysis was to examine the prevalence SERO of cardiac arrhythmias MESHD arrhythmias HP among patients with COVID-19 infection MESHD.Method: PubMed, Google Scholar, and ResearchGate databases were searched for relevant articles from inception until June 14, 2020. Inclusion criteria were: 1) Cohort studies or case series studies; 2) Study population included individuals with confirmed COVID-19 infection MESHD; 3) Arrhythmic events were reported in the study. All other studies were excluded. MedCalc software was used to analyze the pooled data. The random-effect model was utilized to obtain the prevalence SERO of arrhythmia HP arrhythmia MESHD among the included patients and its 95% confidence interval. Cohran's Q and I2 index were used for heterogeneity measurements. The main planned outcome was the prevalence SERO of arrhythmia HP arrhythmia MESHD among patients with COVID-19 infection MESHD.Results: Thirteen studies with a total of 2861 patients met our inclusion criteria. The prevalence SERO of arrhythmia HP arrhythmia MESHD among patients with COVID-19 infection MESHD was 8.1% (95% CI [6.10, 10.37]). 82.8% of the patients who had arrhythmia HP arrhythmia MESHD has severe illness (95% CI [70.916, 92.124]).Conclusion: The prevalence SERO of arrhythmias HP arrhythmias MESHD among patients with COVID-19 infection MESHD is 8.1%, which is much higher than in the general population (2.35%).

    Coronavirus disease 2019 (COVID-19) is a viral pandemic caused by the severe acute respiratory syndrome coronavirus 2 MESHD (SARS-CoV-2). COVID-19 is predominantly defined by respiratory symptoms, but cardiac complications including arrhythmias HP arrhythmias MESHD, heart failure MESHD, and viral myocarditis HP myocarditis MESHD are also prevalent. Although the systemic ischemic MESHD and inflammatory responses caused by COVID-19 can detrimentally affect cardiac function, the direct impact of SARS-CoV-2 infection MESHD on human cardiomyocytes is not well-understood. We used human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) as a model system to examine the mechanisms of cardiomyocyte-specific infection by SARS-CoV-2. Microscopy and immunofluorescence demonstrated that SARS-CoV-2 can enter and replicate within hiPSC-CMs, localizing at perinuclear locations within the cytoplasm. Viral cytopathic effect induced hiPSC-CM apoptosis MESHD and cessation of beating after 72 hours of infection MESHD. These studies show that SARS-CoV-2 can infect hiPSC-CMs MESHD in vitro, establishing a model for elucidating the mechanisms of infection MESHD and potentially a cardiac-specific antiviral drug screening platform.

    Objectives. To describe the age TRANS- and sex-specific prevalence SERO of SARS-CoV-2 disease MESHD (COVID-19) and its prognostic factors. Design. Population-based prospective cohort study on archive data. Setting. Preventive services and hospital care in the province of Reggio Emilia, Northern Italy. Participants. All 2653 symptomatic patients who tested positive for SARS-CoV-2 from February 27 to April 2, 2020 in the province of Reggio Emilia. Main outcome measures. Hospitalization and death up to April 2, 2020. Results. Females TRANS had higher prevalence SERO of infection MESHD than males TRANS below age TRANS 50 (2.61 vs. 1.84 per 1000), but lower in older ages TRANS (16.49 vs. 20.86 per 1000 over age TRANS 80). Case fatality rate reached 20.7% (22/106) in cases with more than 4 weeks follow up. After adjusting for age TRANS and comorbidities, men had a higher risk of hospitalization (hazard ratio (HR) 1.4 95% confidence interval (95% CI) 1.2 to 1.6) and of death (HR 1.6, 95% CI 1.2 to 2.1). Patients over age TRANS 80 compared to < age TRANS 50 had HR 7.1 (95% CI 5.4 to 9.3) and HR 27.8 (95% CI 12.5 to 61.7) for hospitalization and death MESHD, respectively. Immigrants had a higher risk of hospitalization (HR 1.3, 95% CI 0.99 to 1.81) than Italians and a similar risk of death MESHD. Risk of hospitalization and of death MESHD were higher in patients with heart failure MESHD (HR 1.6, 95% CI 1.2 to 2.1and HR 2.3, 95% CI 1.6 to 3.2, respectively), arrhythmia HP arrhythmia MESHD (HR 1.5, 95% CI 1.2 to 1.9 and HR 1.8, 95% CI 1.3 to 2.5, respectively), dementia HP dementia MESHD (HR 1.2, 95% CI 0.9 to 1.8 and HR 1.8, 95% CI 1.1 to 2.8, respectively), ischemic MESHD heart disease MESHD (HR 1.3, 95% CI 1.0 to 1.7 and HR 1.7, 95% CI 1.2 to 2.5, respectively), diabetes MESHD (HR 1.5, 95% CI 1.3 to 1.9 and HR 1.6, 95% CI 1.1 to 2.2, respectively), and hypertensions HP hypertensions MESHD(HR 1.4, 95% CI 1.2 to 2.6 and HR 1.6, 95% CI 1.2 to 2.1, respectively), while COPD increased the risk of hospitalization (HR 1.9, 95% CI 1.4 to 2.5) but not of death MESHD (HR 1.1, 95% CI 0.7 to 1.7). Previous use of ACE inhibitors has no effect on risk of death (HR 0.97, 95% CI 0.69 to 1.34) Conclusions. The mechanisms underlying these associations are mostly unknown. A deeper understanding of the causal chain from infection MESHD, disease onset, and immune response to outcomes may explain how these prognostic factors act.

    Importance: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections MESHD outbreak in China is now a global issue. There is only a limited understanding of the clinical characteristics of patients with SARS-CoV-2 infections MESHD is available.Objective:To describe the characteristics, management strategies, and outcomes of critically ill MESHD patients with SARS-CoV-2 infection MESHD.Design, Setting, and Patients: This is aretrospective, multi-center case series of 50 critically ill MESHD patients with confirmed SARS-CoV-2 infection MESHD who were admitted at Zhongnan Hospital of Wuhan University and Wuhan Pulmonary Hospital in Wuhan, China, from January 8 to February 9, 2020.Exposures:Documented Corona Virus Disease MESHD, 2019 (COVID-19).Main Outcome Measures: Demographic, clinical, laboratory, imaging data were collected along with management strategies, complications and outcomes of enrolled individuals. Results Fifty critically ill MESHD patients with SARS-CoV-2 infections MESHD were enrolled. Their median age TRANS was 62 (range, 29-92) [IQR,49.5-69.0] years, 68% were male TRANS, and 28 (56%) patients had comorbidities, the most common being hypertension HP hypertension MESHD. In this cohort, 20(40%) patients survived ,16(32%) patients died, and the rest remained hospitalized. The invasive mechanical ventilator was used in 36(72%) patients with 15(30%) of them requiring prone positioning, and 17(34%) switched to ECMO. The compliance scores of lungs (Cstat)on the day of ICU admission among survivors were higher than those in non-survivors [42.0(18.0-47.0), vs. 19.5(14.0-24.2), p=0.038].The blood SERO IL-6 levels and neutrophils counts at the first day of ICU admission were significantly higher in non-survivors compared to survivors [123.7(85.3-228.8), vs. 20.2(6.8-67.2) ng/ml, p=0.025 for IL-6, and 20.2(6.8-67.2) vs. 4.01(1.99-7.05) × 10⁹/L, p=0.02 for neutrophils counts].The heart rates, PaCO2, lung injury MESHD scale (LIS), and positive end-expiratory pressure levels were constantly higher for 10 days in non-survivors than those who survived (p<0.05). The frequency of vasopressor uses and neuromuscular blockers was higher in non-survivors from day 1 to day 10 compared to survivors (p<0.05). In the whole cohort, the most common complications were ARDS (97%), shock HP shock MESHD (44%), arrhythmia HP arrhythmia MESHD (38%), acute cardiac injury MESHD (26%), and acute kidney injury HP acute kidney injury MESHD (22%). A secondary bacterial infection MESHD was noted in 17(34%) patients. Univariate analysis indicated that lower lung complianceand higher neutrophil counts at the day of ICU admission were related to higher mortality (p-0.03, and 0.04, respectively)ConclusionWe demonstrated that SARS-CoV-2 infection MESHD-related critical illness predominantly affected old individuals with comorbidities and characterized by severe hypoxemic respiratory failure MESHD respiratory failure HP, often requiring prolonged mechanical ventilation and rescue therapies. Low lung compliance and persistently elevated PaCO2 indicated poor outcomes.
