    Background: Hydroxychloroquine and Azithromycin use is associated with QT interval prolongation and arrhythmias HP. 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 risk management plan.Methods and results: We retrospectively examined arrhythmia HP 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 MESHD pneumonia HP. 7 patients (8.6%) had QTc prolongation 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 MESHD ventricular tachycardia HP. The risk factors significantly associated with QTc≥500 ms were hypokalemia MESHD hypokalemia HP (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.Conclusion: We recorded a low incidence of QTc prolongation ≥500 ms and no ventricular tachycardia MESHD ventricular tachycardia HP events in COVID-19 patients treated with Hydroxychloroquine and Azithromycin using cardiac arrhythmia MESHD arrhythmia HP risk management plan.

    Background: Hydroxychloroquine and chloroquine have been proposed as treatments for coronavirus disease MESHD 2019 (COVID-19) on the basis of in vitro activity, uncontrolled data, and small randomized studies. Methods: The Randomised Evaluation of COVID-19 therapy (RECOVERY) trial is a randomized, controlled, open-label, platform trial comparing a range of possible treatments with usual care in patients hospitalized with COVID-19. We report the preliminary results for the comparison of hydroxychloroquine vs. usual care alone. The primary outcome was 28-day mortality. Results: 1561 patients randomly allocated to receive hydroxychloroquine were compared with 3155 patients concurrently allocated to usual care. Overall, 418 (26.8%) patients allocated hydroxychloroquine and 788 (25.0%) patients allocated usual care died within 28 days (rate ratio 1.09; 95% confidence interval [CI] 0.96 to 1.23; P=0.18). Consistent results were seen in all pre-specified subgroups of patients. Patients allocated to hydroxychloroquine were less likely to be discharged from hospital alive within 28 days (60.3% vs. 62.8%; rate ratio 0.92; 95% CI 0.85-0.99) and those not on invasive mechanical ventilation at baseline were more likely to reach the composite endpoint of invasive mechanical ventilation or death MESHD (29.8% vs. 26.5%; risk ratio 1.12; 95% CI 1.01-1.25). There was no excess of new major cardiac arrhythmia MESHD arrhythmia HP. Conclusions: In patients hospitalized with COVID-19, hydroxychloroquine was not associated with reductions in 28-day mortality but was associated with an increased length of hospital stay and increased risk of progressing to invasive mechanical ventilation or death MESHD.

    Background: Coronavirus disease MESHD 2019 (COVID-19) has been reported to cause worse outcomes in patients with underlying cardiovascular disease MESHD, especially in patients with acute cardiac injury, 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 heart failure MESHD (CHF) 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 MESHD 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 MESHD 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 MESHD had an increased risk of acute cardiac injury 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 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 and hypertension MESHD hypertension HP, respectively. Conclusion: Cardiac involvement in COVID-19 infection MESHD appears to significantly adversely impact patient prognosis and survival. Pre-existence of CHF and high cardiac biomarkers like NT-pro BNP and CK-MB levels in COVID-19 patients correlates with worse outcomes. Keywords: Acute cardiac injury; 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 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 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 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 has severe illness (95% CI [70.916, 92.124]).Conclusion: The prevalence SERO of arrhythmias HP among patients with COVID-19 infection MESHD is 8.1%, which is much higher than in the general population (2.35%).

    Abstract Importance The antimalarial agents chloroquine (CQ) and hydroxychloroquine (HCQ) have been proposed as a potential treatment for COVID-19 due their effect on several cellular processes that impact viral replication. Although more than 100 ongoing trials are testing their efficacy, CQ and HCQ are being used widely in clinical practice, exposing COVID-19 patients to potentially significant cardiac adverse effects. Objective To systematically review the literature and estimate the risk of cardiac toxicity in patients receiving CQ or HCQ for COVID-19. Data Sources A systematic search was conducted on May 27, 2020 of Ovid EBM Reviews, Ovid Embase (1974+), Ovid Medline (1946+ including epub ahead of print, in-process & other non-indexed citations), Scopus (1970+) and Web of Science (1975+) and preprint servers (Medrvix and ResearchSquare) and manual search of references lists. Study Selection Studies that included COVID-19 patients treated with CQ or HCQ, with or without azithromycin, were included as follows: (1) COVID-19 patient population, (2) the study included more than 10 patients receiving either one of the medications, (3) reported electrocardiographic changes and/or cardiac arrhythmias MESHD arrhythmias HP. Data Extraction and Synthesis Study characteristics and endpoints incidence were extracted. Due to the very low incidence of torsades de pointes MESHD torsades de pointes HP (TdP) and other endpoints (rare events), the arcsine transformation was used to obtain a pooled estimate of the different incidences using a random-effects meta-analysis. Meta-regression analyses were used to assess whether the incidence of different endpoints significantly varied by multiple study-level variables specified a priori. Main Outcomes and Measures Pooled Incidence of: (1) change in QTc value from baseline [≥] 60 ms, (2) QTc [≥] 500 ms, (3) the composite of endpoint 1 and 2, (4) TdP arrhythmia or ventricular HP ventricular tachycardia MESHD tachycardia HP (VT) or cardiac arrest HP, (5) discontinuation of treatment due to drug-induced QT prolongation or arrhythmias HP. Results A total of 19 studies with a total of 5652 patients were included. All included studies were of high methodological quality in terms of exposure ascertainment or outcome assessment. Among 2719 patients treated with CQ or HCQ, only two episodes of TdP were reported; the pooled incidence of TdP arrhythmia HP or VT or cardiac arrest HP was 3 per 1000, 95% CI (0-21), I2=96%, 18 studies with 3725 patients. Among 13 studies of 4334 patients, the pooled incidence of discontinuation of CQ or HCQ due to prolonged QTc or arrhythmias HP was 5%, 95% CI (1-11), I2=98%. The pooled incidence of change in QTc from baseline of [≥] 60 ms was 7%, 95% CI (3-14), I2=94% (12 studies of 2008 patients). The pooled incidence of QTc [≥] 500 ms was 6%, 95% CI (2-12), I2=95% (16 studies of 2317 patients). Among 11 studies of 3127 patients, the pooled incidence of change in QTc from baseline of [≥] 60 ms or QTc [≥] 500 ms was 9%, 95% CI (3-17), I2=97%. Mean/median age TRANS, coronary artery disease MESHD, hypertension MESHD hypertension HP, diabetes, concomitant QT prolonging medications, ICU care, and severity of illness in the study populations explained between-studies heterogeneity. Conclusions and Relevance Treatment of COVID-19 patients with CQ or HCQ is associated with a significant risk of drug-induced QT prolongation, which is a harbinger for drug-induced TdP/VT or cardiac arrest HP. CQ/HCQ use resulted in a relatively higher incidence of TdP as compared to drugs withdrawn from the market for this particular adverse effect. Therefore, these agents should be used only in the context of randomized clinical trials, in patients at low risk for drug-induced QT prolongation, with adequate safety monitoring.

    Background SARS-CoV2 infection MESHD are frequently associated with cardiovascular manifestations, in particular with symptomatic acute coronary syndromes MESHD, cardiac arrhythmias MESHD arrhythmias HP and acute heart failure MESHD. However, the elevation of serum SERO troponin seems to be non specific, and a cardiologic diagnostic workup should be performed. We aimed to assess the clinical characteristic and the prevalence SERO of left ventricular (LV) dyssynergy patterns in a cohort of hospitalized non-critically ill COVID-19 patientsMethods Consecutive patients with an objective diagnosis of COVID-19, from February to April 2020. Baseline characteristics and comorbidities was collected. In case of increased troponin levels or symptoms suggestive for a concomitant cardiac syndrome MESHD, patients undergo to serial electrocardiograms, serial Troponin tests and bedside transthoracic echocardiogram.Results 402 consecutive patients were enrolled: 55 patients underwent an echocardiographic exam because of an increase in troponin levels or a suspected myocardial injury. Segmental left ventricular abnormalities were found in 10 (median WMSI 2.03 IQR 1.38-2.75) with a median LV ejection fraction was 30.1 % IQR, median troponin level was 3083 ng/L, median BNP was 761 ng/L. Death MESHD for any cause occurred in 4 patients among patients with regional LV abnormalities and in 3 with normal regional function (p= 0,02).Discussion A single bedside transthoracic echocardiogram performed in non critically ill COVID-19 patients with suspected cardiac injury has the potential to better assist clinicians in their challenging decision process. As an isolated increase of troponin levels is common in COVID patients, a bed-side echocardiographic evaluation of cardiac function should be routinely implemented during their early evaluation.

    Background Exploring the association of coronavirus-2019 disease MESHD (COVID-19) mortality with chronic pre-existing conditions may promote the importance of targeting these populations during this pandemic to optimize survival. The objective of this systematic review and meta-analysis is to explore the association of pre-existing conditions with COVID-19 mortality. Methods We searched MEDLINE, OVID databases, SCOPUS, and medrxiv.org for the period December 1, 2019, to May 1, 2020. The outcome of interest was the risk of COVID-19 mortality in patients with and without pre-existing conditions. Comorbidities explored were cardiovascular diseases MESHD ( coronary artery disease MESHD, hypertension MESHD hypertension HP, cardiac arrhythmias MESHD arrhythmias HP, and congestive heart failure HP heart failure MESHD), chronic obstructive pulmonary disease MESHD chronic obstructive pulmonary disease HP, type 2 diabetes, cancer, chronic kidney disease HP kidney disease MESHD, chronic liver disease MESHD, and stroke MESHD stroke HP. Two independent reviewers extracted data and assessed the risk of bias. All analyses were performed using random-effects models and heterogeneity was quantified. Results Ten chronic conditions from 19 studies were included in the meta-analysis (n = 61,455 patients with COVID-19; mean age TRANS, 61 years; 57% male TRANS). Overall the between-study study heterogeneity was medium and studies had low publication bias and high quality. Coronary heart disease MESHD, hypertension MESHD hypertension HP, congestive heart failure HP heart failure MESHD, and cancer significantly increased the risk of mortality from COVID-19. The risk of mortality from COVID-19 in patients with coronary heart disease MESHD was 2.4 times as high as those without coronary heart disease MESHD (RR= 2.40, 95%CI=1.71-3.37, n=5) and twice as high in patients with hypertension MESHD hypertension HP as high as that compared to those without hypertension MESHD hypertension HP (RR=1.89, 95%CI= 1.58-2.27, n=9). Patients with cancer also were at twice the risk of mortality from COVID-19 compared to those without cancer (RR=1.93 95%CI 1.15-3.24, n=4), and those with congestive heart failure HP heart failure MESHD were at 2.5 times the risk of mortality compared to those without congestive heart failure HP heart failure MESHD (RR=2.66, 95%CI 1.58-4.48, n=3). Conclusions COVID-19 patients with all any cardiovascular disease MESHD, coronary heart disease MESHD, hypertension MESHD hypertension HP, congestive heart failure HP heart failure MESHD, and cancer have an increased risk of mortality. Tailored infection MESHD prevention and treatment strategies targeting this high-risk population are warranted to optimize survival.

    A 59 year old male TRANS patient was admitted to our hospital diagnosed with COVID-19 associated pneumonia MESHD pneumonia HP. Upfront treatment with hydroxychloroquine and azithromycin was started. Because of clinical deterioration MESHD with ARDS, circulatory shock MESHD shock HP and increased hyperinflammatory markers six days later, a cytokine storm rose to the top of differential diagnosis and off-label treatment with IL 6 receptor antagonist Tocilizumab was initiated. Subsequently we observed a dramatic rise of D-dimers indicating coagulopathy. Perimyocarditis with severe cardiac arrhythmia MESHD arrhythmia HP occurred after a second dose was administered. Later the patient died due to multi organ failure. Exacerbation of cytokine storm following treatment with Tocilizumab could not be ruled out, despite a hitherto unreported relationship with COVID-19.
