The goal of this study is to compare the efficacy of a new harvesting technique for an arterial conduit(LIMA - Left Internal Mammary artery) in patients undergoing Coronary artery bypass grafting. The researcher will compare the 1. Time taken to harvest the artery 2. Flow of blood between the two techniques
The objective of this study is to investigate the incidence of death and early postoperative complications, identify potential risk factors, and examine the demographic characteristics of patients and epidemiology of cardiovascular procedures. Our hypothesis is that gaining a more comprehensive understanding of the characteristics of patients who undergo cardiac surgery has the potential to improve outcomes for this patient profile. Thus, information was sought regarding the patient characteristics, surgeries performed, anesthesia administered, incidence of intraoperative and postoperative complications, and risk factors associated with complication and mortality in the ICU. The main questions it aims to answer are: - Incidence of mortality or severe postoperative complications that occur within the first 3 postoperative days or until discharge from the ICU. - Risk factors associated with severe complications in patients who undergo cardiac surgery. - Characteristics of patients, anesthesia and surgical procedures performed - Incidence of severe intraoperative complications and moderate postoperative complications - Evaluate the influence of accumulated fluid balance on outcomes, mortality, and length of ICU stay. - Evaluate mortality in the ICU. - Describe the risk factors associated with mortality.
This goal of this study is to better understand when and where intraoperative transesophageal echocardiography (TEE) should (or should not) be used during coronary artery bypass graft (CABG) surgeries.
The current study evaluated the diagnostic performance for myocardial ischemia of on-site automatic CCTA-derived FFR (CT-FFR) using a commercially available workstation as compared with invasive FFR as a reference. The diagnostic performance of CT-FFR was compared to that of CCTA diameter stenosis.
Early feasibility study of the DurVena Photochemical Tissue Passivation (PTP) device for treatment of saphenous vein grafts in participants undergoing elective coronary artery bypass graft (CABG) surgery. Study to be conducted outside the U.S.
This is a Phase IIA, randomized, double blind, placebo controlled, multicenter study designed to assess the safety, feasibility, and efficacy of umbilical cord derived mesenchymal stromal cells (UC MSCs), administered intravenously (IV) as a single dose or repeated doses, in patients with ischemic cardiomyopathy (ICM).
The feasibility and clinical benefit of using a patient's genotype to guide antiplatelet therapy prescribing has been demonstrated. However, a more precise understanding of who to genotype, what to include on a genetic testing panel, and how to change antiplatelet therapy based on genotype results and other patient-specific factors is needed to optimize the impact of genotype-guided antiplatelet therapy on patient outcomes. The Precision PCI registry is a collaboration between the University of Florida, Gainesville and Jacksonville, USA, the University of North Carolina, Chapel Hill, USA, and University of Maryland, Baltimore, USA. This registry will include a diverse population of patients who undergo Percutaneous Coronary Intervention and clinical CYP2C19 genotyping, assess clinical outcomes over 12 months and collect DNA samples for additional genotyping, and conduct pharmacodynamic analysis of platelet function in a subset of patients. Objectives of the study: 1. Define the influence of African ancestry and other patient-specific factors on clinical outcomes with genotype-guided antiplatelet therapy following PCI in a real-world setting 2. Evaluate the safety and effectiveness of genotype-guided de-escalation of antiplatelet therapy (i.e., switching to less potent antiplatelet therapy) after PCI in a real-world setting 3. Elucidate the effect(s) of genotypes beyond CYP2C19 on platelet reactivity and clinical outcomes with clopidogrel after PCI
Exercise training in cardiac rehabilitation (rehab) is a key part of managing a patient with heart disease. It has been shown that cardiac patients who increase their aerobic ("cardio") fitness by exercise training live longer, have better quality of life, and stay out of hospitals more than patients who do not improve their aerobic fitness. The more a patient improves their aerobic fitness the greater the benefit. But it has been shown that more than half of patients do not improve their aerobic fitness even after participating in cardiac rehab. This may be related to how hard patients are asked to train (their training "intensity"). The way intensity is chosen in current programs is commonly based on a "one-size fits all" method that may not consider that different patients have different abilities. There are more personalized methods to determine training intensity that exist, but these have never been used in cardiac rehab. One method divides intensity into three zones (zone 1 = moderate intensity; zone 2 = heavy intensity; zone 3 = very high intensity) that are based on when an individuals' biological responses to exercise change. The purpose of this study is to see if this approach gives better results in terms of changes in aerobic fitness and if training in the different zones makes a difference. Three groups of patients will be asked to train for 3 months in one of the three intensity zones. Aerobic fitness before and after exercise training will be compared to see which intensity zone results in the largest change.
Given the limited understanding of the impact of statin and N-acetyl cysteine use before angiography in preventing contrast-induced nephropathy (CIN), the objective of this study is to evaluate the effectiveness of atorvastatin in preventing CIN among patients undergoing coronary angiography.
The goal of this clinical trial is to investigate how walking in different environments affects the psychophysiological responses to the stress of individuals with coronary artery disease (CAD) according to their weather sensitivity. Awareness about the potential influence of weather sensitivity on the psychophysiological reactions to stress in patients with CAD disease may contribute to the planning and implementation of actions leading to improved medical care services and preventative measures that help to avoid the worsening of health and well-being in the future.
