    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.

    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 MESHD 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 HP torsades de pointes MESHD ( TdP MESHD) 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 MESHD arrhythmia or ventricular HP ventricular tachycardia MESHD tachycardia HP ( VT MESHD) or cardiac arrest HP cardiac arrest MESHD, (5) discontinuation of treatment due to drug-induced QT prolongation or arrhythmias MESHD 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 MESHD were reported; the pooled incidence of TdP arrhythmia MESHD arrhythmia HP or VT MESHD or cardiac arrest HP cardiac arrest MESHD 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 MESHD 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 HP hypertension MESHD, diabetes MESHD, 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 MESHD, which is a harbinger for drug-induced TdP MESHD/ VT MESHD or cardiac arrest HP cardiac arrest MESHD. CQ/HCQ use resulted in a relatively higher incidence of TdP MESHD 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 MESHD, with adequate safety monitoring.

    Background The novel severe acute respiratory syndrome coronavirus 2 MESHD (SARS-CoV-2) has subsequently spread worldwide. The number of death MESHD has increased rapidly. However, the possible risk factors that lead to death in critical inpatients with coronavirus disease MESHD 2019 (COVID-19) are not yet fully known. This study was to explore the risk factors for mortality of critical inpatients with COVID-19.Methods In this single-centered, retrospective study, we enrolled 113 critical patients with COVID-19 in Renmin Hospital of Wuhan University between Feb 1, 2020 and Mar 15, 2020. Data were collected using a standard method including clinical records and laboratory findings. Outcomes of survivors and death were compared.Results A total of 113 critical patients (from 29 to 95 years) with COVID-19 were recruited, 50 (44.25%) died and 63 recovered (55.75%). The proportion of patients with ventricular arrhythmia HP ventricular arrhythmia MESHD was higher in the death group than the recovery group (24.0% vs 4.4%; p = 0.021), and was higher among myocardial damage MESHD cases than non-myocardial damage cases (26.1% vs 4.3%; p = 0.013). Multivariate analysis confirmed four independent predictors related to mortality of COVID-19: age > 70 yrs (HR 1.84, 95% CI 1.03–3.28), initial neutrophil count more than 6.5 × 109/L (HR 3.43, 95% CI 1.84–6.40), C-reactive protein greater more than 100 mg/L (HR 1.93, 95% CI 1.04–3.59), and lactate dehydrogenase more than 300 U/L (HR 2.90, 95% CI 1.26–6.67). Immunoglobulin treatment (HR 0.39, 95% CI 0.21–0.73) can reduce the risk of death MESHD. There was no significant difference in the QT interval between patients with and without hydroxychloroquine treatment.Conclusions Old age TRANS (> 70 years), neutrophilia HP, C-reactive protein greater more than 100 mg/L and lactate dehydrogenase more than 300 U/L are high-risk factors for mortality of critical patients with COVID-19. The incidence of ventricular arrhythmia HP ventricular arrhythmia MESHD was higher in deceased patients than survivors.
