Patients with cardiovascular disease and diabetes are at potentially higher risk of infection and fatality due to COVID-19. Given the social and economic costs associated with disability due to these conditions, it is imperative that specific considerations for clinical management of these patients be observed. Moreover, the reorganization of health services around the pandemic response further exacerbates the growing crisis around limited access, treatment compliance, acute medical needs, and mental health of patients in this specific subgroup. Existing recommendations and guidelines emanating from respective bodies have addressed some of the pressure points; however, there are variations and limitations vis a vis patient with multiple comorbidities such as obesity. This article will pull together a comprehensive assessment of the association of cardiovascular disease, diabetes, obesity and COVID-19, its impact on the health systems and how best health systems can respond to mitigate current challenges and future needs. We anticipate that in the context of this pandemic, the cardiovascular disease and diabetes Bhaskar et al.CVD and Diabetes in COVID-19 Era patients need a targeted strategy to ensure the harm to this group does not translate to huge costs to society and to the economy. Finally, we propose a triage and management protocol for patients with cardiovascular disease and diabetes in the COVID-19 settings to minimize harm to patients, health systems and healthcare workers alike.

Background Diabetes is a cardiometabolic comorbidity that may predispose COVID‐19 patients to worse clinical outcomes. This study sought to determine the prevalence of diabetes in hospitalized COVID‐19 patients and investigate the association of diabetes severe COVID‐19, rate of acute respiratory distress syndrome (ARDS), mortality, and need for mechanical ventilation by performing a systematic review and meta‐analysis. Methods Individual studies were selected using a defined search strategy, including results up until July 2021 from PubMed, Embase, and Cochrane Central Register of Controlled Trials. A random‐effects meta‐analysis was performed to estimate the proportions and level of association of diabetes with clinical outcomes in hospitalized COVID‐19 patients. Forest plots were generated to retrieve the odds ratios (OR), and the quality and risk assessment was performed for all studies included in the meta‐analysis. Results The total number of patients included in this study was 10 648, of whom 3112 had diabetes (29.23%). The overall pooled estimate of prevalence of diabetes in the meta‐analysis cohort was 31% (95% CI, 0.25‐0.38; z = 16.09, P < .0001). Diabetes significantly increased the odds of severe COVID‐19 (OR 3.39; 95% CI, 2.14‐5.37; P < .0001), ARDS (OR 2.55; 95% CI, 1.74‐3.75; P = <.0001), in‐hospital mortality (OR 2.44; 95% CI, 1.93‐3.09; P < .0001), and mechanical ventilation (OR 3.03; 95% CI, 2.17‐4.22; P < .0001). Conclusions Our meta‐analysis demonstrates that diabetes is significantly associated with increased odds of severe COVID‐19, increased ARDS rate, mortality, and need for mechanical ventilation in hospitalized patients. We also estimated an overall pooled prevalence of diabetes of 31% in hospitalized COVID‐19 patients.

Stroke is a leading cause of death and disability worldwide. The advent of acute reperfusion therapy, intravenous thrombolysis and endovascular thrombectomy, has revolutionized the field of stroke medicine, and neurology in general. Recent studies have implicated a major role of cerebral collaterals in the trajectory of acute ischemic stroke patients receiving reperfusion therapy. Collaterals sustain blood supply to the tissue in the setting of acute ischemia which prevents further expansion of the hypo perfused tissue, playing an important role in determining outcomes after acute ischemic stroke. The use of collateral assessment in routine practice in acute ischemic stroke, let alone in reperfusion therapy, is far from universal and limited. Future work in embedding collateral assessment in standards of care in acute stroke and management is warranted. This article provides a comprehensive update on the diagnostic and prognostic utility of collaterals in acute ischemic stroke and recommendations on collateral-based decision making in acute stroke and steps that can be taken for its rapid uptake in clinical practice.
