Noninvasive Neuromonitoring of Surgery of the Thoracic Aorta
Cardiopulmonary ArrestAortic Aneurysm3 moreThe aim of this prospective, explorative study of noninvasive neuromonitoring was to search potential and practical methods associated with neurological outcome in the perioperative and immediate postoperative setting of surgery of the thoracic aorta. These methods include abbreviated EEG monitoring, near-infrared spectroscopy, transcranial Doppler ultrasound and biochemical markers associated with neuronal damage.
Predicting Fluid Responsiveness in on Pump Coronary Artery Bypass Graft Using Extra Systoles
HypovolemiaCoronary Artery Disease1 moreThe purpose of this study is to determine if extra systoles can be used to predict fluid responsiveness perioperatively in patients undergoing on pump coronary artery bypass graft (CABG) surgery. As an additional study we will investigate the ability of a mini fluid challenge to predict response of a larger volume of fluid.
The FAVOR II China Study
Coronary Artery DiseaseMyocardial Ischemia6 moreQuantitative Flow Ratio (QFR) is a novel method for evaluating the functional significance of coronary stenosis. The purpose of the FAVOR II China study is to evaluate the diagnostic accuracy of on-line QFR with FFR as the reference standard. The secondary purpose is to compare the diagnostic accuracies between online QFR and online QCA, with FFR as the reference standard.
CCTA to Optimize the Diagnostic Yield of Invasive Angiography
Coronary Artery DiseaseThis study aims to reduce patient risk and costs to the healthcare system by improving the diagnostic yield of invasive coronary angiography through existing triage processes to improve risk stratification using Coronary Computed Tomographic Angiography (CCTA) as a first step in low risk patients. All low-risk patients referred for invasive coronary angiography will be potentially eligible for CCTA instead of invasive angiography as a first-line diagnostic test. All CCTAs will be read by both a level 3-trained cardiologist and a radiologist. The results of the CCTA, coupled with evidence-based management recommendations will be sent to the referring physician and an invasive angiogram will be arranged by the HIU triage, only when clearly indicated
Assessment of Coronary Flow Reserve by PET-H215O and FFR. Comparison With Dynamic Acquisition Using...
Coronary Artery DiseaseThe study will assess coronary flow reserve by PET-H215O and FFR in patients suspected of coroanry artery disease. This a comparative study with dynamic acquisition using CZT camera and 99mcTc-mibi. 20 patients will have those measurements.
Patient and Provider Assessment of Lipid Management Registry
HyperlipidemiaHypercholesterolemia15 moreThe purpose of the Patient and Provider Assessment of Lipid Management Registry (PALM) is to gain a better understanding of physicians' cholesterol medication prescribing practices, patient and physician attitudes and beliefs related to cholesterol management, and current utilization of cholesterol-lowering therapies given the new ACC/AHA guideline recommendations. The PALM Registry hopes to allow for the design of ways to improve cholesterol management and decrease the burden of cardiovascular disease (CVD) in the US.
Mechanistic Study of Bleeding Risk in Coronary Patients With Cerebrovascular Disease
Coronary Artery DiseaseCerebral Stroke1 moreBackground: About 5% of patients with acute coronary syndrome (ACS) have had previously ischemic stroke (IS) or transitory ischemic attack (TIA). This is a high-risk population, with a high incidence of ischemic events, and also of bleeding events. While the high ischemic risk in this population is attributed to a higher prevalence of cardiovascular risk factors, their predisposition to bleeding events is not well understood. Hypothesis: The increased bleeding risk in ACS patients with history of cerebrovascular event may be justified by a low platelet activity. Methods: Unicentric, prospective, case-control study, which included approximately 100 post-ACS patients with history of IS/TIA previously to the acute coronary event (Case Group) and 100 patients without IS/TIA (Control group). The groups were matched for gender, age, and ACS type and year of occurrence. All patients were taking aspirin, and the main exclusion criteria were use of dual antiplatelet therapy, previous hemorrhagic stroke, severe renal dysfunction, thrombocytopenia or coagulopathy. Main analysis: Platelet aggregation was evaluated by 6 methods: VerifyNow Aspirin®, VerifyNow P2Y12®, PFA 100®, thrombelastography (ReoRox®), light transmission aggregometry with ADP (LTA ADP) and epinephrine (LTA EPI) as agonists. Additional analysis: genetic, HDL transport and inflammatory evaliation
The Long-term Results of the No-touch Vein Graft to the Left Anterior Descending Artery.
Ischemic Heart DiseaseAtherosclerosisThe purpose of this study was to investigate whether the no-touch saphenous vein grafts that were used in coronary artery bypass surgery between 2003-2008 had a patency rate comparable to the left internal thoracic artery when the vein grafts were anatomised to the left anterior descending artery.
Angina Prevalence and Provider Evaluation of Angina Relief
Stable Coronary Artery Disease CADThe purpose of this study is describe the frequency of chest pain and how chest pain impacts patients' quality of life in the outpatients with chronic coronary artery disease in contemporary cardiology practice settings.
Effects of Integrated Treatment by Traditional Chinese and Western Medicine in Reducing Cardiovascular...
Angina PectorisCoronary Artery Disease7 moreCompared with standardized western medical drug therapy, this study is mainly about whether the combination of standardized western medical drug therapy and Chinese medical continued treatment, can further decrease the rate of cardiovascular events for stable angina patients and change the condition of angina.
