Restore EF Observational Study
Coronary Artery DiseaseUnstable Angina3 moreA multi-center, prospective, observational, non-interventional single arm, study of the intermediate-term clinical outcomes collected from electronic health records of high-risk patients which have previously undergone standard of care prophylactic Impella support for a non-emergent percutaneous coronary intervention (PCI).
Evaluation of the LVivo Image Quality Scoring (IQS)
Heart DiseasesArrhythmia6 moreThe study includes two parts: Part 1: 100 examinations of patient referred for echo evaluation, containing clips that were acquired from the 4CH apical view were collected retrospectively. Each study includes 10 clips that represent typical user scanning errors Offline evaluation of the system (by batch processing) shall be performed by comparing the system output to preliminary quality tagging by experienced sonographers Part 2: Live scans of apical 4CH clips of patients with indication for POCUS examination will be performed by POC physicians LVivo IQS shall be used (on Lumify) during the scan for patients that meet inclusion criteria until 50 exams will be collected. 3 sec of each scan shall be saved, and Image quality score (IQS) shall be documented Saved scans shall be reviewed by an expert physician to determine whether they are clinically interpretable
Utility of a Molecular Personalized Coronary Gene Expression Test (Corus CAD or ASGES) on Cardiology...
Angina PectorisCoronary Artery Disease6 moreTo investigate whether the use of Corus CAD (Age/Sex/Gene Expression score - ASGES) blood assay changes the diagnostic testing pattern in patients referred to a cardiologist for the evaluation of chest pain or anginal equivalent symptoms.
Understanding Clinician Utilization of Corus CAD (Age/Sex/Gene Expression Score - ASGES) in Clinical...
Coronary Artery DiseaseAngina Pectoris6 moreThe purpose of this study is to understand the use of Corus CAD also known as Age/Sex/Gene Expression score (ASGES) in the clinical decision making process of patients who underwent the evaluation of chest pain or anginal equivalent symptoms. Specifically, to better understand whether the use of the assay in clinical decision making resulted in changes in noninvasive diagnostic test ordering or diagnostic yield of additional tests ordered and/or invasive angiography.
Hemodynamics During the Soccer Championship 2012
Severe CardiomyopathyAngina4 moreThe purpose of this study is to determine in soccer fans whether and to which extend positive or negative emotions during the European soccer Championship affects Central Hemodynamics, Arterial Stiffness, Heartrate and Endothelial Dysfunktion.
PCP Use of a Gene Expression Test (Corus CAD or ASGES) in Coronary Artery Disease Diagnosis
Chest PainCardiovascular Diseases6 moreThis is a prospective, multi-center study examining the clinical impact of the Corus CAD (Age/Sex/Gene Expression score - ASGES) assay in approximately 250 evaluable subjects with no history of obstructive coronary artery disease who now present with chest pain or anginal-equivalent symptoms to a primary care physician (PCP) for evaluation.
Understanding the Role of Autoimmune Disorders on the Initial Presentation of Cardiovascular Disease...
Myocardial InfarctionIschemic Stroke9 moreAutoimmune diseases are diseases in which inappropriate immune responses that have the capability of harming host cells play an important role. Evidence suggests that the presence of certain autoimmune diseases such as rheumatoid arthritis or systematic lupus erythematosus increase the risk of cardiovascular disease (CVD). However, this evidence is inconsistent for autoimmune disorders and no systematic approach has been previously used to study the relationship between a range of common autoimmune disorders and specific forms of cardiovascular diseases such as myocardial infarction, intracerebral and subarachnoid haemorrhage, or venous thrombosis. The investigators will use linked electronic health records to investigate whether commonly diagnosed autoimmune disorders are associated with increased risk of CVD development and whether effects differ in men and women and change with age.
The Role of Alcohol Consumption in the Aetiology of Different Cardiovascular Disease Phenotypes:...
Chronic Stable AnginaUnstable Angina20 moreThe association between alcohol consumption and cardiovascular disease (CVD) has mostly been examined using broad endpoints or cause-specific mortality. The purpose of our study is to compare the effect of alcohol consumption in the aetiology of a range of cardiovascular disease phenotypes.
Safety Study of Kudiezi (a Chinese Medicine Injection) Used in Hospitals in China
Coronary Heart DiseaseAngina PectorisThis study was advocated by Institute of Basic Research in Clinical Medicine, China Academy of Chinese Medical Sciences in October 2011. It was funded by China major scientific and technological specialized project for 'significant new formulation of new drugs'. Kudiezi is kind of Chinese Medicine injection used for treating coronary heart disease and angina pectoris in many Chinese hospitals. The purpose of this study is to determine adverse drug events or adverse drug reaction in large sample size 30,000 patients.
Association of Endothelial Function and Clinical Outcomes in Subjects Admitted to Chest Pain Unit...
Myocardial InfarctionDeath3 moreIt is recognized that endothelial dysfunction is a major factor contributing to the atherogenic process. Abnormal function of the endothelium is detectable prior to obvious intimal lesions in patients with risk factors for atherosclerosis. Endothelial dysfunction is a systemic disorder and a key variable in the pathogenesis of atherosclerosis and its complications. Measurement of peripheral vasodilator response with fingertip peripheral arterial tonometry (PAT) technology (EndoPAT; Itamar Medical, Caesarea, Israel) is emerging as a useful method for assessing vascular function. EndoPAT may be a potential valid test increasing the accuracy, sensitivity and specificity for detection of subjects to chest pain unit (CPU) with chest pain but no obvious coronary artery disease (CAD). This is a relatively fast non-invasive bedside test, relatively low-cost and has no side effects. Therefore, the primary objective of the study is to test the hypothesis that abnormal endothelial function as assessed by EndoPAT testing will increase the prediction of the short (in-hospital) and long-term (1-year) outcome of patients presenting to the chest pain unit.
