Filter by:The purpose of this study is to test whether sodium nitrite affects the expression of cellular proteins important for metabolic and vascular function in vascular offcuts and cardiac biopsies taken from patients undergoing coronary artery bypass grafting (CABG) surgery.
The accuracy of devices like the recent FDA-clearance of the Omron HeartGuide™ Blood Pressure sensor in robust clinical settings remain in question and thus form the underpinning of this research study. The objective of this pilot prospective study is to assess the accuracy of the Omron Blood Pressure sensor as compared to arterial line blood pressure monitoring.
Secondary mitral insufficiency is a common complication of heart failure, aggravating symptoms and prognosis, and may be responsible for worsening dyspnea, pulmonary edema, and excess mortality. It is essentially a ventricular rather than a valvular disease, whose origin may be ischemic or not. It is induced by a geometrical and contractile modification of the left ventricle which causes an imbalance between the tensile and the closing forces of the mitral valve thus causing a defect of coaptation and the increase of the surface between the mitral leaves and the ring in systole (tenting). Dynamic mitral insufficiency is defined by changes in the degree of severity of regurgitation as a function of hemodynamic conditions. During exercise, the course of mitral insufficiency is variable and is not predicted by the degree of regurgitation at rest. The worsening of the leak is also well correlated with the onset of dyspnea on exertion in patients with left Ventricular Ejection Fraction heart failure (LVEF reduced). Nevertheless, there is little data available in the literature on the factors predisposing to the development of stress-related mitral insufficiency, as well as its clinical and echocardiographic impact in the cardiac insufficiency patient, particularly in the case of preserved LVEF (6.7%). The identification of echocardiographic data at rest to predict and anticipate the behavior of mitral insufficiency in the effort (aggravation or stability / disappearance), would allow a simplified evaluation and a better management in this population of patients for which the evaluation in echography of effort can be technically complex and limited (difficulty of quantification of the mitral leak, time of effort sometimes too short ...).
Blood and urine samples of over 200 pediatric subjects (over 28 days to 3 years) undergoing complex cardiac surgery with cardiopulmonary bypass (CPB) will be collected at several time points to measure corresponding biomarkers such as serum creatinine, serum urea concentration, or NephroCheck test ([TIMP-2]*[IGFBP7) to evaluate the diagnostic performance of AKI by NephroCheck test .

Nowadays, minimally invasive cardiothoracic surgery techniques are being performed to treat patients with coronary heart diseases. These newly developed procedures include laparoscopic techniques that do not require median sternotomy, which has several beneficial effects for both patient and the hospital. Although retrospective data show promising results with respect to clinical outcomes (e.g. 30-day mortality rate, intensive care unit length of stay), no prospective data with respect to patient centered outcomes (e.g. quality of recovery, quality of life) are available yet. Therefore, the aim of this observational prospective study is to explore several patient centered and clinical outcomes of patients that are treated with these newly developed minimally invasive cardiac procedures. The comparative group consists of patients undergoing open CABG (invasive) and patients undergoing a Transcatheter Aortic Valve Implantation (TAVI).
Establish the effectiveness of the Bay Labs, Inc. EchoGPS software in enabling RNs to acquire echocardiograms. In this study an echocardiogram protocol using the EchoGPS interface with the Terason uSmart 3200t, an FDA 510(k)-cleared, commercially available ultrasound device will be performed. Participants will have two scans, one by a registered nurse (RN) using the Terason uSmart 3200t with EchoGPS (Study Exam) and one by a sonographer using the Reference Device without EchoGPS guidance (Control Exam), under the same protocol. Study is non-significant risk (NSR).
Aim(s)/Objective(s) - To evaluate the safety and efficacy of triple antithrombotic therapy in patients taking DAPT of aspirin and a P2Y12 inhibitor in addition to either a NOAC or warfarin for the prevention of thromboembolic or acute coronary syndrome (ACS) events in patients with non-valvular atrial fibrillation (AF), history of coronary artery disease (CAD)/stent placement or recurrent ACS event. - To determine the Methodist Health System (MHS) prescribing practices and patterns in cardiac patients with a history of AF who are admitted for CAD or an ACS event requiring PCI. Hypothesis Primary Hypothesis Cardiac patients with a history of AF and an indication for long-term NOAC who are also prescribed DAPT following an ASC event or revascularization with stenting will demonstrate a significant difference in cardiovascular outcomes and major bleeding events when compared with warfarin-based triple therapy.
The DELPhi system is a software device that is used for the noninvasive evaluation of brain plasticity and connectivity. The DELPhi software uses EEG and TMS devices as accessories. Standard electro-physiological acquisition is performed using TMS to evoke regional neuronal potentials measured as EEG data. TMS-EEG data is analyzed with regards to conventional, well established characteristics of neuronal network plasticity and connectivity.
