This project is evaluating the validity of regional saturation monitoring in evaluating changes in the mesenteric perfusion. Regional saturation monitoring is a standard of care in many institutions, including NCH. Advances in the technology and recent approval of the use of CASMED devices for this purpose will allow us to use this technology more effectively. We aim to evaluate if there is a change in the mesenteric blood flow during the pre, intra and post operative period for the hybrid procedure and the balloon atrial septostomy procedure (BAS).
Obstructive sleep apnea(OSA) is an important identifiable cause of hypertension. Previous study has suggested that OSA significantly increases cardiovascular morbidity and mortality, especially in patients with pre-existing cardiovascular disease.The standardized treatment of moderate/severe OSA is continuous positive airway pressure (CPAP). Most of short-term trials indicated that CPAP treatment reduced BP in patients with OSA. But relevant studies have a relative short duration with only but few more than one year. In our opinion, they are not sufficient to detect the real effect of CPAP on reduction in BP. Besides, the impact of OSA on metabolic disorder is still unclear.We hypothesized that long-term CPAP treatment could reduce blood pressure and improve metabolic disorder in patients with coronary heart disease (CHD)and OSA.
The purpose of this study evaluate the effect of the method of administration of autologous bone marrow mononuclear cells for the duration of of functioning aorto-coronary bypass grafts in the surgical treatment of coronary heart disease, to assess the degree of effectiveness depending on the method of transplantation (intramyocardial, intracoronary, combined).
The purpose of this Randomized Study to evaluate the safety and efficacy of the Excel-II DES compared to the EXCEL DES in the treatment of patients with de novo coronary artery lesions.
The purpose of the study is to assess the feasibility and safety of a transplantation of cardiac-committed progenitor cells derived from human embryonic stem cells in patients with severe heart failure.
HIV-infection is associated with an increased risk for cardiovascular disease. Especially patients with low CD4+ counts have a higher incidence of structural heart disease. Myocardial T1 relaxation time, as well as T1-derived extracellular volume fraction are relatively new methods for non-invasive myocardial tissue characterization, including diffuse myocardial fibrosis. In our study HIV-patients with high and low CD4+ counts are examined on a 3T MRI scanner (Ingenia 3T, Philips Medical, Best, Netherlands). Scanning protocol includes common SSFP sequences, STIR imaging and LGE [Late gadolinium enhancement]. All HIV patients are treated in the HIV outpatient clinic of the hospital's Internal Medicine department and have an unremarkable history of cardiac disease. Patients are recruited from all over Germany. In order to obtain reference values, a subgroup of healthy, age-matched controls is included in this study. Aim of this study is to show differences in T1- and ECV-values in the investigated subgroups. In addition, we also want to create cut-off values for healthy and affected myocardium in asymptomatic HIV-infected patients. This study could show whether myocardial T1 mapping is a potential screening parameter for beginning heart disease as part of an HIV-infection, and whether an application in routine diagnostic is reasonable.
Cardiovascular diseases are the main cause of death worldwide. Aerobic fitness is related to long-term survival and a reduction in mortality and recurrent nonfatal myocardial infarction in subjects with cardiovascular disease. However, the majority of cardiac patients do not engage in enough physical activity to obtain benefits or in the long-term struggle to maintain a physically active lifestyle. There is a need for innovative rehabilitation methods aiming at increasing longer-term adherence and hence more sustained effects on health related physical fitness. One strategy might be the use of home-based training in combination of telemonitoring guidance. Therefore, the main objective of this randomized controlled clinical trial is to compare the longer-term (=1 year) effects of a 3-month supervised center-based rehabilitation program with a patient-tailored home-based cardiac rehabilitation program with telemonitoring guidance in CAD patients (phase III). The primary outcome measure is physical fitness. It is hypothesized that patients randomized to a home-based training program with telemonitoring guidance will demonstrate higher levels of physical activity at one year of follow-up, resulting in higher levels of physical fitness, compared to patients who have been enrolled to the supervised center-based cardiac rehabilitation program or control group. Ninety patients will be randomized to Home-based training, a center-based cardiac rehabilitation program or an advice only group (= control group). Assessment will be performed at baseline, immediately at completion of the intervention and at one-year of follow-up and will include measurements of exercise tolerance, cardiovascular risk factors, physical activity, muscle strength, endothelial function, health-related quality.
The purpose of this study is to compare three different revascularization strategies in patients with multi-vessel coronary disease: MICS CABG, OPCABG and ONCABG. The study hypothesis: MICS CABG (Minimally invasive cardiac surgery coronary artery bypass grafting) has advantages in comparison with conventional off-pump (OPCABG) and on-pump coronary artery bypass grafting (ONCABG) concerning major adverse cardiac and cerebral events (MACCE) and procedural success.
The goal of this study is to gather input from patients who have undergone PCI, their family and/or caregivers, and clinicians to develop a patient decision aid. The purpose of the decision aid is to deliver information, including individualized estimates of patients' restenosis risk, in an understandable format that would be informative and assist in decision-making for patients undergoing PCI.
