Transcriptomics in cardiac surgery

ABSTRACT: 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

Transcription profiling of human atrial tissue from patients undergoing coronary artery bypass graft surgery to determine the effect of anesthesia on gene expression

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.

Changes in cardiac transcription profiles following on-pump coronary artery bypass grafting

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. Myocardial samples were collected, prior and after grafting, from patients undergoing on-pump coronary artery bypass grafting with cardiopulmonary bypass and cardiac arrest.

Changes in cardiac transcription profiles following off-pump coronary revascularization surgery

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. Myocardial samples were collected, prior and after grafting, from patients undergoing off-pump coronary artery bypass grafting.

Remote ischemic preconditioning in on-pump coronary artery bypass graft surgery

Project description:In this placebo-controlled randomized controlled trial, we tested whether remote ischemic preconditioning (RIPC) elicited by four 5-minute cycles of 300 mmHg of cuff inflation/deflation of the lower limb would reduce myocardial necrosis in isoflurane-anesthetized patients undergoing on-pump coronary artery bypass graft surgery. Secondary outcomes were the perioperative release of the biomarkers NTproBNP, hsCRP, S100, atrial transcriptional profiles, and short- and long-term clinical outcomes. RIPC with concomitantly applied isoflurane did not affect the release of biomarkers or clinical outcome. NTproBNP release correlated with isoflurane- but not RIPC-induced transcriptional changes.

Reversibility of etomidate-induced contractile arrest through activation of myocardial autophagy

Project description:Anesthetic management of heart failure patients undergoing noncardiac surgery remains challenging due to cardiac suppressive properties of anesthetics. Due to varying electrophysiological properties, small and large animals are not good models for studying human myocardial anesthetic responses. Here we use hypertrophic (HCM), dilated (DCM) and healthy human induced pluripotent stem cells derived cardiomyocytes (hiPSC-CMs) to evaluate the cardiac suppression of propofol and etomidate. We demonstrate that propofol and etomidate act through GABAA receptors and contractile inhibition can occur without cell-cell junction. At supraphysiological dosage (100mM), we discovered that cardiac suppression induced by etomidate is reversible while propofol is not. Using transcriptome profiling, we uncover that etomidate was capable of inducing autophagy, likely through induction of cytosolic calcium. Lack of autophagy induction in propofol treated cardiomyocytes were associated with increased apoptosis. Together, we provide the robustness of using hiPSC-CMs as an in vitro cardiotoxicity platform for anesthetics. To delineate how etomidate confers cardioprotection during contraction inhibition, we performed transcriptome profiling on DCM hiPSC-CMs treated with either 10 μM propofol, 10 μM etomidate or DMSO control.
