The diagnostic value of circulating microRNAs for middle-aged (40–60-year-old) coronary artery disease patients

OBJECTIVE: Circulating microRNAs have been recognized as promising biomarkers for various diseases. The present study aimed to explore the potential roles of circulating miR-149, miR-424 and miR-765 as non-invasive biomarkers for the diagnosis of coronary artery disease in middle-aged (40–60-year-old) patients. METHODS: Sixty-five stable coronary artery disease patients (49–57 years old), 30 unstable coronary artery disease patients (49–58 years old), and 32 non-coronary artery disease patients (49–-57 years old) who were matched for age, sex, smoking habits, hypertension and diabete...
