Acute chest pain is a common presentation in patients with COVID-19. Although noninvasive cardiac imaging modalities continue to be important cornerstones of management, the pandemic has brought forth difficult and unprecedented challenges in the provision of timely care while ensuring the safety of patients and providers. Clinical practice has adapted to these challenges, with several recommendations and societal guidelines emerging on the appropriate use of imaging modalities. In this review, we summarize the current evidence base on the use of noninvasive cardiac imaging modalities in COVID-19 patients with acute chest pain, with a focus on acute coronary syndromes.

Objective: Since the emergence of the COVID-19 pandemic at the end of 2019, the number of affected cases has not stopped rising. Similarly, the number of scientific publications and pre-prints has been increasing exponentially, with an effort to understand this disease more and find a proper solution. The purpose of this article is to review the current understanding of the novel coronavirus. Background: The latest COVID-19 pandemic caused by the SARS-CoV-2 has spread globally ever since it emerged in Wuhan's city in China. This rapidly spreading disease has changed our lives in unimaginable ways, spreading fear and uncertainty due to the lack of knowledge and the flooding with new information, which lacks the scientific method and cannot be critically appraised. The purpose of this article is to gather some of the best knowledge that has been published so far in a unified narrative review, making it easy for the scientific community to review the most accurate and recent understandings about COVID-19. Methods: We screened relevant articles using a specified number of keywords and specific databases, including PubMed and Embase. We selected peer-reviewed English published material related to the topic, except for a few pre-prints that we deemed necessary to include. We also screened the reference lists of these articles to find relevant publications with the same criteria. Discussion: This narrative overview comprises several subsections that discuss the epidemiology, virology, pathogenesis, clinical manifestations, diagnostic methods, and management of the disease. We also presented a section on the implications of the disease in pregnancy. We wrapped up the review with a special division regarding the response to COVID-19,  which has been diverse in different countries. Conclusion: COVID-19 has been a serious global health threat with a high transmission and case fatality rate, particularly in vulnerable populations. Epidemiologic models have so far guided the response, but they need to be interpreted carefully, with an understanding of their limitations. The disease's response has varied among different countries; with no current vaccine or standard treatment, the world stands in fear, maximizing preventive strategies to reduce the damages caused by this virus. This manuscript presents a summary of everything that is so far known about COVID-19 to make it easier for the medical community to overview the disease that has changed the world.
