Enhanced Trained Immunity in Peripheral Monocytes in Unstable Angina With Elevated High-Sensitivity C-Reactive Protein

ABSTRACT: Despite effective secondary prevention for coronary heart diseases, recurrent events remain high. Elevated high-sensitivity C-reactive protein (hsCRP) indicates increased inflammation risk. This study aimed to investigate the trained immunity of circulating monocytes in unstable angina (UA) patients with elevated hsCRP. We analyzed CD14+ monocytes from UA patients, comparing high-risk (hsCRP ≥3 mg/L) and low-risk (hsCRP <1 mg/L) groups. We assessed cytokine production and conducted metabolic, transcriptional, and epigenetic profiling. Patients with elevated hsCRP exhibited enhanced proinflammatory responses, glycolytic activity, and altered immune profiles, indicating sustained monocyte trained immunity, which contributes to residual inflammation risk in cardiovascular disease.

Characterisation of Myocardial Infarction and Unstable Angina with mRNA Profiles from Whole Blood of individual patients

Characterisation of Myocardial Infarction and Unstable Angina with mRNA Profiles from Whole Blood of individual patients

Project description:Coronary artery disease (CAD) remains a leading cause of death worldwide. Acute coronary syndromes (ACS) are the spectrum of diseases arising from coronary atherosclerotic plaque rupture, ranging from unstable angina (UA; clinical symptoms of cardiac ischemia without myocardial necrosis) to myocardial infarction (MI; clinical symptoms of cardiac ischemia with myocardial necrosis). We use microrray to identify changes in pathways following MI.This study examines mRNA expression levels in human whole blood at 7 and 30 days post ACS. Patients with MI are compared to those with UA (not healthy controls), thus focusing on differences in mRNA expression due to the acute clinical events rather than underlying atherosclerosis and its treatment. We recruited 26 patients presenting with acute coronary syndromes (ACS); 8 with unstable angina (UA) and 18 with MI. Supplementary files: The files contain the combined values (for each group) of the single patients' expression levels, the fold changes and the significance levels associated. Gene expression levels were estimated using probabilistic models implemented in puma (Propagating Uncertainty in Microarray Analysis, bioconductor.org), which provide estimates for the variance and credibility interval for probe level errors of each transcript. FCs were calculated after combining gene expression values within groups using Bayesian hierarchical model, incorporating probe level errors into the variance estimate. Significance levels for differentially expressed genes were detected by calculating the probability of positive log ratio (PPLR). The higher is the probability the more confident is the estimate of that positive FC, conversely the lower is the probability the more confident is the estimate of that FC to be negative. This model was implemented in the pumaComb and pumaDE modules within puma. file1 = mRNA_MI_combday30_exprs file2 = mRNA_MI_combDay7_exprs

miRNA profiling of plasma samples: patients with unstable coronary artery disease and controls

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).

Expression data from normal human and unstable angina patient.

Project description:20 patients with unstable angina were divided into patient group by using coronary angiography. The sex- and age-matched healthy individuals were enrolled as control group. Venous bloods were collected for extracting RNA. We used the Human Genome U133 plus 2.0 genechip produced by Affymetrix to detail the global gene expression in blood sample from normal human and unstable angina patient. 1 control and 2 test samples.

Profiling of circulating microRNAs in patients with unstable angina pectoris

Project description:We profiled miRNA expression in the plasma from healthy subjects and patients with unstable angina pectoris to obtain differentially expressed plasma miRNAs. We randomly selected 25 samples from each group and combined into a sample pool. In this way we obtained 7 and 6 sample pools in control group and case group, respectively. miRNA levels in the plasma were detected with miRCURY LNATM microRNA Array, 6th gen -hsa, mmu & rno.
