BACKGROUND: Cardiovascular diseases (CVDs) remain the leading cause of mortality globally, with mitochondrial dysfunction playing a key role in their pathogenesis. SIRT3 (Sirtuin 3), a mitochondrial deacetylase, has emerged as a critical regulator of mitochondrial function and oxidative stress, with evidence linking its reduction to the progression of CVDs. This meta-analysis aimed to evaluate the association between SIRT3 levels and CVDs in order to elucidate its role in CVD pathogenesis and its potential as a biomarker.
METHODS: A systematic search of MEDLINE and Embase databases was conducted up to August 2024, adhering to PRISMA guidelines. Observational studies evaluating SIRT3 levels in human patients with CVDs as compared to healthy controls were included.
RESULTS: 8 studies comprising 397 participants were included in this meta-analysis. Overall, SIRT3 levels were found to be significantly lower in individuals with CVDs compared to healthy controls (SMD: 1.08, 95% CI: 0.495-1.662, p = 0.0032). The reduction in SIRT3 levels was most pronounced in hypertension (SMD: 1.82) and dilated cardiomyopathy (SMD: 1.08).
CONCLUSION: This meta-analysis provides compelling evidence of gsignificantly reduced SIRT3 levels in CVD patients, highlighting its critical role in cardiovascular diseases. These findings underscore the potential of SIRT3 as a biomarker and therapeutic target in CVDs.
