Filter by:The research will be carried out in the Cardio Vascular Surgery (CVS) Intensive Care Unit (ICU) of Ankara Training and Research Hospital (TRH) . Patients will be divided into two Experimental (n=24) and control (n=24) groups. Simple randomization method will be used in the study, provided that there are equal numbers of male and female patients in the experimental and control groups, regardless of the age of the patients. Patients in the experimental group will use a digital window. The "Patient Information Form","Richard-Campbell Sleep Questionnaire_RCSQ " and " Day and Night Perception Form" will be used in the data collection phase. Ethics committee approval was received from Ankara Yıldırım Beyazıt University Ethics Committee in order to conduct the study.
The objective of the BIOSTEMI ES study is to assess the long-term clinical outcomes with the Orsiro ultrathin-strut biodegradable polymer sirolimus-eluting stent compared to the Xience thin-strut durable polymer everolimus-eluting stent up to 5 years of follow-up among patients with STEMI undergoing primary PCI, enrolled in the BIOSTEMI trial.
This traditional feasibility study aims to capture preliminary safety and effectiveness information on a near-final Investigational Device design to adequately plan the forthcoming pivotal study.
The aim of the proposed study is to evaluate microcirculatory alterations in patients undergoing open heart surgery with minimal invasive versus conventional extracorporeal circulation. Positive clinical results evidenced with goal-directed perfusion and cerebral oximetry monitoring could be attributed to preserved microcirculation at tissue level.
This trial is a prospective, two center single group registration pilot trial aiming to evaluate the product safety, and provide information for the later confirmatory test design according to the results.
This study aims to investigate the effects of cardiac rehabilitation on sleep quality and sleep duration in patients after coronary artery bypass graft.
This study aims to determine whether the neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) can be used as predictors of coronary heart disease (CHD) in CKD patients undergoing dialysis at Moewardi General Hospital Surakarta. It was hypothesized that NLR and PLR, which have been identified as inflammatory biomarkers, would be significantly related to increased arotid intima-media thickness (CIMT) in CKD patients undergoing dialysis. This study is an observational analytic study using a cross-sectional approach conducted at department of renal-hypertension and hemodialysis unit in Moewardi General Hospital in Surakarta, Indonesia from January to July 2022.
Coronary Microvascular Dysfunction has been consistently shown to play a considerable role in pathophysiology of Ischaemia with non-obstructed coronary arteries (INOCA). While the both diagnoses are individually related to remarkably worse outcome, there is no available method to simultaneously determine INOCA-CMD endotypes in vessel level, during the invasive diagnosis. The investigators hereby hypothesize that, combined intracoronary electrocardiogram (IC-ECG) (considering the high sensitivity and specificity of IC-ECG for studied vessel-territory) and intracoronary doppler can simultaneously and successfully identify vessel specific coronary microvascular dysfunction and resulting ischemia, which may potentially enable immediate diagnosis and endotyping of CMD-INOCA subgroups during the invasive assessment of first ANOCA episode, obviating the need for further ischemia-studies such es SPECT, which have considerably higher costs and lower sensitivity. Major coronary arteries of patients aged between 18 - 75 without obstructing coronary artery disease who have previously documented ischemia with non-obstructed coronary arteries (INOCA) via coronary angiogram and myocardial perfusion scan will be evaluated simultaneously with IC-ECG and intracoronary Doppler during rest and under adenosine induced hyperaemia. Performance of the combined system to identify Coronary Microvascular Dysfunction with structural and functional subgroups as defined by abnormal Coronary Flow Reserve (CFR) and Hyperemic Microvascular Resistance (HMR) and Ischemia in downstream territories of same vessel area (as defined by perfusion scan) is intended to be determined. The investigators also intend to interrogate the possible relationship between dynamic changes in IC-ECG parameters and invasively obtained intracoronary hemodynamic data.
Abstract Significance: Cardiac surgery-associated acute kidney injury (CSA-AKI) is common and has serious immediate and long-term sequelae. Better early prediction of those at highest risk and greater understanding of underlying pathological processes are needed to prevent or minimise damage. Hypotheses - Dynamic changes in systemic endothelial glycocalyx (Glx) and microcirculatory parameters during coronary artery bypass graft (CABG) surgery are predictive of CSA-AKI. - Mechanisms for Glx degradation during CABG surgery are akin to those during sepsis Aims - Investigate Glx and microcirculatory health throughout CABG surgery and recovery and their association with CSA-AKI. - Explore association between inflammation and Glx degradation during CABG surgery. Methodology 1. Prospective cohort study: serial sampling and microcirculatory perfusion imaging of 70 patients undergoing CABG surgery with evaluation of CSA-AKI predictors, including plasma Syndecan-1. 2. Examination of inflammation and cardiometabolic proteome and association with vascular changes 3. In vitro mechanistic assessment of Glx degradation and relative timing of organelle exocytosis in cultured endothelial cells in response to patient serum, targeting identified candidate mediators. Impact: Enhancing CSA-AKI risk stratification with new mechanistic biomarkers will enable individualised management of at-risk patients, and pathophysiological insights will create possible therapeutic targets, thus reducing morbidity, mortality and cost of CSA-AKI.
