Circulating endothelial cells were isolated from patients experiencing acute myocardial infarction (n=49) and from healthy cohorts (n=50). The patients were separated into a discovery cohort (n=43) for biomarker discovery and model training; and into a validation cohort (n=56) for biomarker validation and model testing.
Twenty-eight patients with ST-segment elevation myocardial infarction (STEMI) were included. The blood was collected on the 1st day of myocardial infarction, after 4-6 days, and after 6 months. Control group comprised 14 patients with stable coronary artery disease (CAD), without history of myocardial infarction. Gene expression analysis was performed with Affymetrix GeneChip® Human Gene 1.0 ST microarrays and GCS3000 TG system.
The genome-wide study used matched case-control design, with 97 samples of 90 patients in three disease groups. Matched control samples were used and several (7) technical replicates were performed.
Three patients with acute myocardial infarction and three healthy people in Northeast Chinese Han people were recruited,total RNA of each samples were extracted from peripheral blood to hybridize with Affymetrix microarrays.
In this study, we used exon array profiling to investigate biomarker gene analyzing 49 patients samples (six time points) and 6 control samples. Whole-blood cell drawn from an antecubital vein at six time points following STEMI diagnosis. The first time (T0) was on patient admission to the Emergency Unit prior to receiving any medication. The second time (T2) blood collection occurred after successful mechanical reperfusion and stenting of the infarct artery within 2 h after T0. Collectio...
338 individuals in the Emory Cardiovascular Biobank in Midtown Atlanta., 219 men and 119 women. The age of individulas were between 26 and 85 (mean 62). 333 Caucasian (CAU), 4 African American (AFA), 1 South Asian (SAS).
The 32 patients of this study were divided in 2 groups corresponding to the extreme quartiles of FE values. The first group are the patients with low Ejection fraction and the second group are the patients with high ejection fraction.Blood sample: 2.5 mL harvested in PAXgene® Blood RNA tubes (PreAnalytix)RNA extraction: PAXgene® Blood RNA kit (Qiagen)We used a Universel Reference RNA (Stratagene)RNA amplification and labelling: kit Amino Allyl MessageAmp II (Ambion)We hybridized 4 microarray...
Monocytes play a central role in the inflammatory response that follows acute myocardial infarction (MI). In order to study phenotypic adaptation of this cell type, we investigated patterns of monocyte gene expression in circulating monocytes at various stages of MI. Circulating monocytes were isolated from venous blood of MI patients at three time points: t1: within 6 hours after onset of chest pain (acute phase), t2: 3 days after MI (subacute phase), t3: 90 days after MI (chronic phase).
