INTRODUCTION: There is limited literature on coronavirus disease 2019 (COVID -19) complications such as thromboembolism, cardiac complications etc. as possible trigger for stroke. Hence, we aim to evaluate the prevalence and outcomes of COVID-19 related cardiovascular complications and secondary infection and their possibility as potential triggers for the stroke. METHODS: Data from observational studies describing the complications [acute cardiac injury (ACI), cardiac arrhythmias (CA), disseminated intravascular coagulation (DIC), septic shock, secondary infection] and outcomes of COVID-19 hospitalized patients from December 1, 2019 to June 30, 2020, were extracted following PRISMA guidelines. Adverse outcomes defined as intensive care units, oxygen saturation less than 90%, invasive mechanical ventilation, severe disease, and in-hospital mortality. The odds ratio and 95% confidence interval were obtained, and forest plots were created using random-effects models. A short review of these complications as triggers of stroke was conducted. RESULTS: 16 studies with 3480 confirmed COVID-19 patients, prevalence of ACI [38%vs5.9%], CA [26%vs5.3%], DIC [4%vs0.74%], septic shock [18%vs0.36%], and infection [30%vs12.5%] was higher among patients with poor outcomes. In meta-analysis, ACI [aOR:9.93(95%CI:3.95-25.00], CA [7.52(3.29-17.18)], DIC [7.36(1.24-43.73)], septic shock [30.12(7.56-120.10)], and infection [10.41(4.47-24.27)] had higher odds of adverse outcomes. Patients hospitalized with acute ischemic stroke and intracerebral hemorrhage, had complications like pulmonary embolism, venous thromboembolism, DIC, etc. and had poor outcomes CONCLUSION: The complications like acute cardiac injury, cardiac arrhythmias, DIC, septic shock, and secondary infection had poor outcomes. Patients with stroke were having history of these complications. Long term monitoring is required in such patients to prevent stroke and mitigate adverse outcomes.

Globally, coronavirus is causing more social, economic and healthcare disruption than expected. The emerging literature has reported the complications of coronavirus, and the mortality and risk factors involved, including cardiac injury and multisystem organ failure. In this meta-analysis, we aim to evaluate the association of elevated troponin I levels with outcomes in COVID-19 hospitalized patients. Observational studies describing troponin I levels and outcomes of COVID-19 hospitalized patients from 1 December 2019 to 15 August 2020 were identified. Data were extracted following PRISMA guidelines with a consensus of two independent reviewers. Adverse outcomes were defined as admission to intensive care units (ICUs), oxygen saturation <90%, invasive mechanical ventilation (IMV), and in-hospital mortality. The odds ratio (OR) and 95% confidence interval (95% CI) were obtained and forest plots were created using random-effects models. Ten studies with 3982 confirmed COVID-19 patients were included. In patients with poor outcomes, the prevalence of elevated troponin I levels was 51% (690/1341). In meta-analysis, patients with elevated troponin I levels had higher odds of poor outcomes compared to better outcomes with pooled OR of 7.92 (95% CI: 3.70-16.97; p<0.00001) with 70% heterogeneity (p=0.0005). Our meta-analysis suggests that COVID-19 patients with elevated troponin I levels had a higher risk of poor outcomes. Hence, evaluating the troponin I levels might be helpful in preventing risk of cardiac complications and other organ dysfunction.
