Cardiac Manifestations

The COVID-19 pandemic has brought devastating consequences worldwide. One of the most confusing aspects of this virus that have been discovered so far is the occurrence of severe cardiac manifestations in patients with underlying heart disease. Several studies have shown that COVID-19 patients with pre-existing cardiac conditions are at a significantly increased risk of developing adverse cardiac events, including heart failure, arrhythmias, and even sudden cardiac death. The underlying mechanisms of these cardiac complications in COVID-19 patients are yet to be fully understood, but it is hypothesized that the virus could cause a direct injury to cardiac cells, trigger an inflammatory response, and predispose patients to hypercoagulability, which eventually culminates in thromboembolic events. Further, the interactions of the SARS-CoV-2 virus with the renin-angiotensin-aldosterone system (RAAS) and other pathways may also lead to cardiovascular damage. Early recognition and management of cardiac involvement in COVID-19 patients are crucial to prevent life-threatening complications. At the same time, the importance of close monitoring of patients with cardiac conditions amidst the pandemic is emphasized, as their risk of developing severe complications with COVID-19 is higher. In summary, COVID-19 is a complex and multifaceted disease with far-reaching implications for the human body, and the cardiovascular system is no exception. Further research is required to improve our understanding of the pathophysiology of cardiac involvement in COVID-19, and more importantly, to develop effective management strategies to overcome these challenges.
