SIRT1: a potential therapeutic target for coronary heart disease combined with anxiety or depression.

Coronary heart disease (CHD) combined with anxiety or depression is increasingly receiving attention in the clinical field of cardiology, and exploring the comorbidity pathological mechanisms of cardiovascular disease combined with psychological disorders is a hot research topic for scholars in this field. Current research suggests that Silent Information Regulatory Factor 1 (SIRT1) may serve as a potential biomarker for the comorbidity mechanism and treatment of CHD with anxiety or depression. SIRT1 is considered a promising therapeutic target for CHD combined with anxiety or depression, with the ability to regulate inflammatory cytokine levels, alleviate oxidative stress damage, activate multiple signalling pathways, reduce platelet hyperresponsiveness, and exert neuroprotective and cardioprotective effects. In this comprehensive review, we deeply studied the structure, function, and mechanism of SIRT1, and discussed its protective effects in the cardiovascular and nervous system. The latest progress in the mechanism of SIRT1's role in CHD combined with anxiety or depression was emphasised, including its specific mechanisms in regulating inflammatory response, alleviating oxidative stress, and mediating various signalling pathways. In addition, this article also summarises the therapeutic potential of SIRT1 as a potential biomarker in patients with CHD combined with anxiety or depression.
