Abstract
Introduction: Multisystem Inflammatory Syndrome in Children (MIS-C) is a rare but severe condition that can develop in children who have had COVID-19. It can lead to cardiovascular complications, possibly caused by endothelial dysfunction and arterial stiffness.
Methods: This study aimed to investigate the cardiovascular health of children with MIS-C compared to healthy controls. Fifty-nine children with MIS-C and Fifty-nine healthy controls were included in this cohort study. Non-invasive techniques were used to measure the brachial artery's flow-mediated dilation (FMD), aortic distensibility (AD), and aortic strain (AS).
Results: The MIS-C group had significantly higher systolic blood pressure (P= 0.012) and pulse pressure (P= 0.046) than the control group. FMD, AS, and AD were lower in the MIS-C group but with no significant differences.
Conclusion: Children suffering from MIS-C have exhibited higher pulse pressure, which indicates that they may have potential arterial stiffness. They also had lower FMD, which suggests endothelial dysfunction. FMD is a more reliable indicator of endothelial dysfunction in MIS-C patients than aortic strain. These findings highlight the significance of early assessment and monitoring of cardiovascular complications in MIS-C patients. Endothelial dysfunction and arterial stiffness are known risk factors for future cardiovascular events.
