The study interest was reached

Metabolic syndrome and hyperuricemia were both associated with inflammation, leading to diversities of cardiovascular disease such as left ventricular diastolic dysfunction, but the relationship among these entities remained unclear. The aim of the present study focuses on the association among hyperuricemia, diastolic dysfunction and inflammatory biomarkers in apparently healthy individuals with metabolic syndrome

Apparently healthy individuals with metabolic syndrome were prospectively and consecutively enrolled since August 2017. Blood samples were obtained after participants are fasting for at least 12 hours, including serum uric acid, high-sensitivity C-reactive protein, high-sensitivity interleukin-6, tumor necrotizing factor alpha, fasting glucose, glycosylated hemoglobin, insulin, lipid profile, creatinine, alanine aminotransferase, sodium, potassium, and calcium. All echocardiographic parameters were measured in accordance with the American Society of Echocardiography guidelines.

Inclusion Criteria:

1. Age between 20 to 75 years
2. Metabolic syndrome

Exclusion Criteria:

1. Left ventricular ejection fraction <40%
2. Severe valvular heart disease
3. Significant structure heart diseases such as hypertrophic, dilated, infiltrative or restrictive cardiomyopathy, or congenital heart disease
4. Persistent or chronic atrial fibrillation
5. Status post cardiac surgery, including coronary artery bypass surgery of valve intervention
6. Status post intra-cardiac device implantation
7. Chronic obstructive pulmonary disease
8. Severe anemia
9. An obvious systemic disease that interferes left ventricular diastolic dysfunction such as acute coronary syndrome
