Filter by:The MYSTAR-5-YEAR study controls the patients 5 years after treatment with combined (intramyocardial and intracoronary) delivery of autologous BM-MNCs. The clinical endpoint of this prospective non-randomized observational study is the MACCE, defined as major adverse cardiac and cerebrovascular events. Patients will be investigated by echocardiography, SPECT and MRI. 2D (NOGA-guided SPECT) and 3D (NOGA-guided MRI) imaging will refine the evaluation with more exact analysis of the intramyocardial injected areas (ROI).
This pilot study seeks to compare the change in energy expenditure and fitness levels of patients seen in the Children's Hospital Preventive Cardiology program receiving standard of care provider exercise counseling to similar patients receiving Frequency, Intensity, Time, Type (FITT) exercise prescription and counseling combined with BodyMedia supported by an online interactive tool. The investigators primary hypothesis is that this interactive technology coupled with support from a exercise specialist will increase the energy expenditure of the investigators patients over standard of care provider counseling. The investigators Secondary hypotheses include greater improvement in measured physical fitness Peak oxygen consumption (VO2max), oxygen consumption (VO2) at anaerobic threshold (AT) and ventilation/carbon dioxide (VE/VCO2) slope, lipid profiles, blood pressure, arterial stiffness, body mass index (BMI), BMI percentile, and self-efficacy in the intervention group compared to control.
This is a prospective, observational, cohort study to evaluate the relative efficacy and safety of Resolute Integrity stent compared to other (drug eluting stents) DES.
Esophageal electrocardiography (eECG) has important advantages compared to standard ECG recordings. Coronary artery disease leading to myocardial ischemia is very common and has potentially severe consequences for patients. To date, the investigators don't know the influence of ischemia on the eECG. The goal of the present study is to assess ischemic changes of the eECG induced by balloon occlusion of coronary arteries in patients undergoing coronary angiography.
Are novel vascular closure devices noninferior to manual compression regarding access site complications after coronary angiography?
The primary objective of this observational study is to evaluate the function (patency) of cryopreserved saphenous vein allografts used as coronary artery bypass grafts (CABG) for patients with occlusive coronary artery disease.
The purpose of this study is to determine whether stress echocardiography or computed tomography (CT) of the heart is better at diagnosing emergency room chest pain patients to select appropriate candidates for hospitalization and further work-up.
The aim of the present study was to assess the efficacy of thoracic epidural anesthesia followed by postoperative epidural infusion and patient-controlled epidural analgesia with ropivacaine/fentanyl in off-pump coronary artery bypass grafting
Ionizing radiation has a number of harmful effects in humans. The most important among these is the induction of cancer. It is assumed that damage to DNA in the nucleus of a single cell can induce cancer. Among the different types of lesions inducted, DNA double-strand breaks (DSBs) are considered to be the most relevant effects that can initiate carcinogenesis. The investigators are already conducting several other studies to prospectively compare the inducted DSBs by coronary CT-angiography and conventional coronary angiography. Extending these examinations to investigate the induced DSBs by myocardial scintigraphy allows a comparison of all three relevant imaging methods of the heart that incorporate ionizing radiation. To evaluate this, the investigators are planning to examine patients who are scheduled for a clinically indicated myocardial scintigraphy. These examinations are routinely done by the Department of Nuclear Medicine in either a 1-day or a 2-day protocol according to the diagnostic reference values of the Federal Department for Radiological Protection. Blood samples will be taken from these patients at predefined time steps before and after the examination and DNA double-strand breaks will be determined from these blood samples specifically considering the applied activity of the tracer and the exposition kinetics.
The main purpose of this study is to compare myocardial perfusion imaging using Rubidium-82 PET with Tc-99m-MIBI SPET, in the evaluation of significant Coronary Artery Disease (CAD).
