A rare presentation of an elderly patient with acute lymphocytic leukemia and platelet count of zero associated with ST-elevation myocardial infarction, pulmonary thromboembolism in the setting of SARS-CoV 2: a case report.

BACKGROUND: Novel coronavirus disease 2019 (COVID-19) is known to lead not only to severe acute respiratory syndrome, but also can result in thromboembolic events in both the venous and the arterial circulation by inducing coagulation disorders. The potential causes of coagulopathy are inflammation, platelet activation, endothelial dysfunction, and stasis. The thrombotic events including pulmonary embolism, deep venous thrombosis as well as intracatheter thrombosis are more likely to develop in patients infected with severe form of SARS-CoV-2 who are admitted to ICU. Furthermore, these events contribute to multi-organ failure. CASE PRESENTATION: Herein, we report a case of an immunocompromised COVID-19 elderly patient with acute lymphocytic leukemia who developed myocardial infarction with ST elevation in the setting of acute pulmonary thromboembolism in the presence of zero platelet count. Despite successful urgent coronary revascularization and platelet transfusion, the patient eventually died after failed resuscitation efforts. CONCLUSION: Patients with COVID-19 infection are at a greater risk of developing cardiovascular complications, but their appropriate management can decrease the risk of fatal events. Coronary thrombosis associated with pulmonary thromboembolism in the setting of thrombocytopenia is a rare and a complex to manage condition. Significance of single antiplatelet agent in STEMI with thrombocytopenia merits further studies. According to expert opinions and literature reviews, we must avoid dual antiplatelet therapy in these patients and keep platelet transfusion as a standard therapy to avoid drastic bleeding complications.

Coronavirus Disease 2019 and Catheterisation Laboratory Considerations: "Looking for Essentials".

The current coronavirus disease 2019 (COVID-19) outbreak is a significant health crisis that impacts every healthcare system worldwide, and has led to a dramatic change in dealing with different diseases during the pandemic. Interventional cardiologists are frontline workers who deal with many cardiovascular emergencies, either in patients with proven COVID-19 or in suspected cases. Many heart associations worldwide are currently setting appropriate recommendations for the management of emergency cardiac interventions. In this expert opinion, the authors highlight the essential requirements in the cardiac catheterisation laboratory during the COVID-19 pandemic.
