Aortic valve sclerosis was associated with significantly lower serum adiponectin levels compared to controls with normal aortic valves (9.7 vs. 11.7 μg/ml; P=0.034).

Are serum adiponectin levels associated with aortic valve sclerosis?
Serum adiponectin levels are significantly lower in patients with aortic valve sclerosis, suggesting a potential role in the progression of degenerative aortic valve disease.
Absolute Event Rate: 9.7% vs 11.7%
p-value: p=0.034
AIMS: The sclerotic lesions of the aortic valve share common features with atherosclerosis. An anti-inflammatory protein, adiponectin, seems to have a protective effect on the cardiovascular system. The goal of our study is to determine adiponectin levels in patients with aortic sclerosis and to compare these values with the control group with similar age and cardiovascular risk profile. METHODS: Sixty-eight patients with aortic sclerosis and 40 controls were included. Serum adiponectin levels were measured by solid-phase enzyme-linked immunosorbent assay. RESULTS: There were no significant differences regarding age, sex and other cardiovascular risk factors between groups. Also, mean body mass index values were similar. The rate of mitral annular calcification and left ventricular hypertrophy were significantly higher in patients with aortic sclerosis. Among laboratory variables, high-sensitive C-reactive protein (hsCRP) levels were significantly higher in patients with aortic sclerosis than in those without (4.0 ± 2.9 vs. 2.9 ± 2.3 mg/dl, P = 0.04). Adiponectin levels were found to be significantly lower in aortic sclerosis group than in controls (9.7 ± 4.4 vs. 11.7 ± 4.9 μg/ml, P = 0.034). In the whole group, adiponectin levels were significantly correlated with BMI (r = -0.22, P = 0.02), white blood cell count (r = -0.2, P = 0.03), hsCRP (r = -0.25, P = 0.008), total cholesterol (r = -0.18, P = 0.05), high-density lipoprotein (HDL) cholesterol (r = 0.31, P = 0.001) and triglyceride (r = -0.36, P < 0.001). CONCLUSION: In patients with aortic sclerosis, serum adiponectin levels were significantly lower compared with those with normal aortic valves. Our findings suggested that adiponectin might play a role in the progression of degenerative aortic valve disease.
Çabuk et al. (Thu,) conducted a case-control in Aortic valve sclerosis (n=108). Aortic valve sclerosis vs. Controls with normal aortic valves was evaluated on Serum adiponectin levels (p=0.034). Aortic valve sclerosis was associated with significantly lower serum adiponectin levels compared to controls with normal aortic valves (9.7 vs. 11.7 μg/ml; P=0.034).
