Project description:This study describes a circulating miRNA signature of unstable angina (UA), which may be used as a novel biomarker for unstable coronary artery disease (CAD). The Taqman low-density miRNA array were used to identify distinct miRNA expression profiles in the plasma of patients with typical UA and angiographically documented CAD (UA group, n = 13) compared to individuals with non-cardiac chest pain (control group, n = 13). EDTA-plasma samples were obtained before the cardiac catheterization procedure.The study included 2 groups that were classified according to angiographic evidence and clinical evaluation of chest pain. Patients with chest pain or discomfort but with angiographic exclusion of coronary atherosclerosis were enrolled in the control group (n = 13). Chest discomfort referred to the following complaints: chest pain, pressure, tightness, or heaviness; pain that radiated to the neck, jaw, shoulders, back, or one or both arms; and persistent shortness of breath. Patients with typical unstable angina (UA) and angiographically documented CAD were enrolled in the UA group (n = 13).

Project description:To understand the mechanism of coronary artery aneurysmal dilatation, we identified and compared the expression of circulating miRNAs in three groups of patients. Group 1 enrolled patients with aneurysmal dilatation of coronary arteries (n = 20), Group 2 included patients with angiographically confirmed coronary artery disease (CAD), whereas Group 3 included 20 patients with normal coronary arteries. The miRNAs were isolated from plasma and profiled using PCR arrays miRCURY LNA Serum/Plasma Focus PCR Panels. We demonstrated that the plasma miRNAs levels were significantly different in Group 1 in collation with Group 2 and Group 3 (fold change > 2 and p < 0.05). The comparison of Group 1 with Group 3 identified twenty-one significantly up-regulated and two down-regulated miRNAs in patients with aneurysmal coronary artery dilatation compared to the control groups. Moreover, we identified six up-regulated and two down-regulated miRNAs in patients with CAD compared to the controls. The third comparison revealed four up-regulated and three down-regulated miRNAs in Group 1, when compared to CAD patients. In conclusion, this study demonstrates the specific signature of plasma miRNA, namely up-regulated and down-regulated, in patients with abnormal dilatation of coronary arteries and the comparison between the groups consisting of atherosclerotic and control patients.
Project description:Coronary artery disease (CAD) is the leading cause of mortality worldwide. We aimed to compare expression of miRNA in the affected artery of acute myocardial infarction (ST-elevation myocardial infarction) male patients versus healthy individuals (control). Blood samples were collected during coronary catheterization from proximal culprit coronary arteries aimed for the interventions or from a random artery in control samples. RNA isolated from serum was used for miRNA high throughput sequencing.
Project description:In this research, two 4-hydroxy-2-nonenal modified peptides with differential performance were identified in the plasma of patients with coronary artery disease, whether their antibodies were different in the plasma of patients with coronary artery disease and healthy people.
Project description:We took samples of subcutaneous adipose tissue from the sternum (SAT) and epicardial adipose tissue (EAT) from a site adjacent to the right coronary artery in cases with coronary disease and controls without coronary disease. Cases had significant coronary disease and were undergoing coronary artery bypass surgery. Controls all had coronary angiograms and did not have significant coronary disease.
