Programmed cell death, including necroptosis, plays an important role in cardiovascular diseases such as viral myocarditis. This review summarizes the evidence on the pathogenesis, molecule mechanism, diagnosis, and potential treatment strategies of viral myocarditis, with a special focus on the novel mechanism of necroptosis for cardiomyocytes death. Studies have shown that tumor necrosis factor-alpha (TNF-alpha) is involved in the activation of necroptosis and may have diagnostic implications for viral myocarditis.
Programmed cell death (PCD), including necroptosis, has emerged as a significant pathway in cardiovascular diseases. The infection of viral myocarditis (VMC) could cause cardiomyocytes degeneration, necrosis, and immune-inflammatory myocardial response. In this review, we summarized and evaluated the available evidence on the pathogenesis, molecule mechanism, diagnosis, and potential treatment strategies of viral myocarditis, with a special focus on the novel mechanism of necroptosis for cardiomyocytes death. Studies have shown that tumor necrosis factor-alpha (TNF-alpha) is an important cytokine involved in the activation of necroptosis; an elevated level of TNF-alpha is continually reported in patients suffering from VMC, implicating its involvement in the pathogenesis of VMC. It is of great interest to explore the clinical implication of TNF-alpha. We subsequently conducted a meta-analysis on the efficacy of serum TNF-alpha expression level and its diagnostic accuracy on acute viral myocarditis detection. Taken together, the review demonstrates a compelling role of necroptosis involved in the pathogenesis of VMC. Further, applying TNF-alpha as a serological marker for the diagnosis of VMC may be a useful strategy.
