Aim: To investigate the clinical value of HDAC4 in coronary heart disease (CHD) patients. Methods: The serum HDAC4 levels were determined by ELISA in 180 CHD patients and 50 healthy controls. Results: HDAC4 was decreased in CHD patients compared with healthy controls (p < 0.001). HDAC4 was negatively linked with serum creatinine (p = 0.014), low-density lipoprotein cholesterol (p = 0.027) and C-reactive protein (p = 0.006) in CHD patients. Moreover, HDAC4 was inversely related to TNF-α (p = 0.012), IL-1β (p = 0.002), IL-6 (p = 0.034), IL-17A (p = 0.023), VCAM1 (p = 0.014) and Gensini score (p = 0.001). Unfortunately, neither HDAC4 high (vs low) (p = 0.080) nor HDAC4 quartile (p = 0.268) estimated major adverse cardiovascular event risk. Conclusion: Circulating HDAC4 levels have disease monitoring value but are less valuable in estimating prognosis in CHD patients.

What was this article about? This study aimed to assess the clinical significance of identifying a marker named histone deacetylase 4 (HDAC4) in coronary heart disease (CHD) patients. What was done? Blood was taken from 180 CHD patients and 50 healthy controls, and their blood HDAC4 levels were evaluated. What were the results? HDAC4 levels were higher in CHD patients than in the controls. The CHD patients with a higher HDAC4 level had good kidney health and lower lipid profile, milder inflammation, good vascular status and less narrowing in their blood vessels. However, the HDAC4 level was not found to predict the risk of future cardiovascular disease. What do the results mean? A higher HDAC4 level in the blood of CHD patients suggests a better symptomatic disease status.
