An alternative way of SARS-COV-2 to induce cell stress and elevated DNA damage risk in cardiomyocytes without direct infection

Genotoxic risks in patients with COVID-19

The COVID-19 pandemic has caused numerous deaths worldwide. Despite the mitigation of infection manifestations in recent months, the possible consequences of the epidemic remain difficult to predict. Genotoxicity and subsequent development of neoplasms are possible outcomes. This review summarises the data on these questions. Studies from several countries have reported increased levels of DNA damage in nucleated blood cells of patients with severe forms of COVID-19 infection. The level of DNA damage can be used as a prognostic factor for the disease outcome. It is considered that SARS-CoV-2 spike proteins play a crucial role in DNA damage; however, the virus also inhibits the DNA repair system. Co-morbidities and use of antiviral drugs may also contribute to DNA damage in patients with COVID-19.

Beyond acute infection: molecular mechanisms underpinning cardiovascular complications in long COVID

SARS-CoV-2, responsible for the global COVID-19 pandemic, has manifested significant cardiovascular implications for the infected population. These cardiovascular repercussions not only linger beyond the initial phase of illness but have also been observed in individuals who remain asymptomatic. This extended and pervasive impact is often called the post-acute COVID-19 syndrome (PACS) or "Long COVID". With the number of confirmed global cases approaching an alarming 756 million, the multifaceted challenges of Long COVID are undeniable. These challenges span from individual health complications to considerable burdens on worldwide healthcare systems. Our review comprehensively examines the complications of the persistent cardiovascular complications associated with COVID-19. Furthermore, we shed light on emerging therapeutic strategies that promise to manage and possibly mitigate these complications. We also introduce and discuss the profound concerns regarding the potential transgenerational repercussions of SARS-CoV-2, emphasizing the need for a proactive and informed approach to future research and clinical practice.
