ABSTRACT
Occurrence of cardiac arrhythmias in COVID-19 patients with myocardial injuries is common, and it is potentially a lifethreatening complication. The current study presents the published literature on cardiac arrhythmia occurrence in COVID-19 patients during 2020. We aimed to evaluate the association among cardiac arrhythmias, acute cardiac injury, and disease severity. Databases, including PubMed, Science Direct, and Scopus, were searched to find studies describing subjects with cardiac arrhythmias and COVID-19. In this study, we recruited 4,355 patients with COVID-19, collected from 13 studies. Relevant data were manually extracted and compared among two groups: arrhythmia as a complication of COVID-19 and cardiac injury as a complication of COVID-19. The pooled prevalence of cardiac arrhythmia was 19% (95%CI: 12% to 29%), compared to 9% (95%CI: 5% to 18%) in acute cardiac injury. Compared to patients without arrhythmias, the probability of developing severe symptoms was increased by ten folds in patients with arrhythmias. In addition, acute cardiac injury significantly increased the severity of COVID-19 by nearly 15-folds. No significant publication bias was indicated by either the visual symmetry or the Egger’s test. In conclusion, the incidence of cardiac arrhythmias and acute cardiac injury is highly associated with the severity and the mortality rate of COVID-19.

ABSTRACT
Background: The literature on COVID-19 infection is growing every single day, and evidence of presence or absence of association between obesity and COVID-19 adverse outcomes should be revisited. Therefore, this study summarizes the pooled association of obesity with COVID-19 adverse outcomes and mortality. Methods: We searched PubMed and Science direct databases using specific terms and defined criteria. Data were analyzed using Comprehensive Meta-Analysis V2 (Biostat, Englewood, NJ, USA)) random-effect models were used to calculate the odds ratio (OR) with 95% confidence intervals (95% CIs) of infection severity and mortality associated with obesity. Results: Results revealed that obesity is not associated with COVID-19 mortality (OR = 1.1; 95%CI: 0.8 to 1.3) but with other adverse outcomes (OR = 2.4; 95%CI: 1.7 to 3.3). Conclusion: Our findings support previous findings that obesity is associated with COVID-19 severity.
ABSTRACT
Objectives: The aim of this study was to evaluate the association of pre-existing cardiovascular comorbidities, including hypertension and coronary heart disease, with coronavirus disease 2019 (COVID-19) severity and mortality. METHODS: PubMed, ScienceDirect, and Scopus were searched between January 1, 2020, and July 18, 2020, to identify eligible studies. Random-effect models were used to estimate the pooled event rates of pre-existing cardiovascular disease comorbidities and odds ratio (OR) with 95% confidence intervals (95% CIs) of disease severity and mortality associated with the exposures of interest. RESULTS: A total of 34 studies involving 19,156 patients with COVID-19 infection met the inclusion criteria. The prevalence of pre-existing cardiovascular disease in the included studies was 14.0%. Pre-existing cardiovascular disease in COVID-19 patients was associated with severe outcomes (OR, 4.1; 95% CI, 2.9 to 5.7) and mortality (OR, 6.1; 95% CI, 2.9 to 12.7). Hypertension and coronary heart disease increased the risk of severe outcomes by 2.6 times (OR, 2.6; 95% CI, 1.9 to 3.6) and 2.5 times (OR, 2.5; 95% CI, 1.7 to 3.8), respectively. No significant publication bias was indicated. Conclusion: COVID-19 patients with pre-existing cardiovascular comorbidities have a higher risk of severe outcomes and mortality. Awareness of pre-existing cardiovascular comorbidity is important for the early management of COVID-19.
ABSTRACT
The emerging coronavirus disease (COVID-19) swept the world, affecting more than 200 countries and territories. As of August 22, 2020, the pandemic infected more than 23,329,752 including 807,054 patients who have died. Although the main clinical features of the pandemic disease are respiratory, cerebrovascular comorbidities emerged as one of the leading causes of death associated with COVID-19. Different case reports have indicated that C-reactive protein (CRP) and D-dimer (pro-inflammatory biomarkers) were elevated in COVID-19 patients, which can significantly increase the risk of ischemic stroke. Available data on cerebrovascular complications in COVID-19 patients were collected and a meta-analysis was designed and carried out to evaluate the risk of severity and mortality associated with high levels of CRP and D-dimer levels in COVID-19 patients. In addition, we aimed to describe the overall event rate of pre-existing cerebrovascular disease in COVID-19 patients. In our analysis, 5,614 cases have been studied, out of these patients 164 cases have developed cerebrovascular comorbities. Cerebrovascular comorbidity increased the risk of disease severity (odd ratioâ=â4.4; 95% CI: 1.48 to 12.84) and mortality (odd ratioâ=â7.0; 95% CI: 2.56 to 18.99). Statistical analyses showed that CRP and D-dimer serum levels were elevated by six-folds in the severe cases of COVID-19 patients. This significant increase in these two proteins levels can serve as a vital indicator for COVID-19 patients who are at increased risk of severe COVID-19 cerebrovascular complications, such as stroke.
