Project description:This SuperSeries is composed of the following subset Series: GSE12485: Changes in cardiac transcription profiles following off-pump coronary revascularization surgery GSE12486: Changes in cardiac transcription profiles following on-pump coronary artery bypass grafting Refer to individual Series
Project description:To investigate changes in cardiac transcription profiles caused by off-pump cardiac surgery, we collected myocardial samples, prior and after grafting, from patients undergoing off-pump coronary revascularization surgery. The transcriptional profile of the mRNA in these samples was measured with gene array technology. Changes in transcriptional profiles can be correlated with the stress response of heart to off-pump surgery. Keywords: human, cardiac, OPCAB coronary surgery, gene expression.

Project description:To investigate changes in cardiac transcription profiles caused by on-pump cardiac surgery, we collected myocardial samples, prior and after grafting, from patients undergoing on-pump coronary artery bypass grafting with cardiopulmonary bypass and cardiac arrest. The transcriptional profile of the mRNA in these samples was measured with gene array technology. Changes in transcriptional profiles can be correlated with the stress response of heart to surgery, cardiopulmonary bypass and cardiac arrest. Keywords: human, cardiac, CABG coronary surgery, gene expression, cardiopulmonary bypass.

Project description:Anesthetic gases elicit organ protection in patients undergoing coronary artery bypass graft (CABG) surgery. This study aimed at identifying myocardial transcriptional phenotypes and anesthetic-induced changes in gene expression to predict cardiovascular biomarkers and cardiac function after off-pump CABG. Keywords: cardiac surgery, anesthetics
Project description:Anesthetic gases elicit organ protection in patients undergoing coronary artery bypass graft (CABG) surgery. This study aimed at identifying myocardial transcriptional phenotypes and anesthetic-induced changes in gene expression to predict cardiovascular biomarkers and cardiac function after off-pump CABG. Experiment Overall Design: Patients scheduled for off-pump CABG were randomized into a group with the anesthetic gas sevoflurane (n=10) or the intravenous anesthetic propofol (n=10). Atrial samples were collected at the beginning and end of bypass surgery to determine gene expression profiles.
