Active clinical trials for "Chest Pain"

The purpose of this study is to determine whether the combination of copeptine and troponin adds diagnosis information to that provided by troponin alone or the combination of troponin and myoglobin. Hypothesis : If the values of troponin and copeptin are not elevated, diagnosis of acute myocardial infarction can be ruled out without prolonged monitoring and serial blood sampling.

The aim of this study is to define the best prognostic strategy for patients presenting suspected acute CORONARY syndrome, between MSCT and stress echocardiography.

The purpose of this study is to determine whether coronary artery computed tomography scanning is a more rapid, less expensive and safe alternative to standard diagnostic evaluation of patients with acute chest pain in the emergency room.

The purpose of this study is to see whether individuals who access the "911" emergency medical system with a heart attack or severe chest pain will receive more timely hospital treatment and better outcomes if hospital clinicians are provided with earlier and more complete electrocardiography (ECG) information.

This study will investigate the influence of intra-operative use of remifentanil versus fentanyl on the percentage of patients with chronic thoracic after cardiac surgery via sternotomy. Secondary quantitative sensory testing is performed to determine thermal and electrical detection and pain threshold and the difference in pain variability scoring. Postoperative pain scores, analgesic use, genetic variances and costs are measured.

Objectives The CATCH trial (CArdiac cT in the treatment of acute CHest pain) is a prospective randomized controlled trial designed to evaluate the clinical value of cardiac multidetector computed tomography (MDCT) as a first-line diagnostic strategy in patients with acute chest pain, compared to a conventional functional-based testing strategy. Methods: Consecutive patients admitted with acute chest pain of suspected cardiac origin, but normal electrocardiogram and biomarkers were randomized to evaluation with 320-MDCT coronary angiography (CT-guided group) or with standard bicycle exercise test and/or myocardial perfusion imaging - MPI (Control group). After one year, patients will be followed-up, with registration of clinical endpoints such as Cardiac death, myocardial infarction, need for revascularisation, admittance for heart related problems, sustained chest pain, live quality score, use of medication.

The purpose of this study is to determine whether coronary artery CT scanning or nuclear stress testing is better at diagnosing chest pain patients with coronary artery disease to select appropriate candidates for coronary catheterization and re-vascularization.

The purpose of this clinical trial is to study the ability of a radioactive drug called "Technetium Glucarate" to detect whether the cause of chest pain in patients entering the emergency department with no obvious signs of heart attack is due to a condition called Acute Coronary Syndrome (ACS). The drug will be injected intravenously. After one or two hours the patient will undergo an imaging procedure to detect if the drug has accumulated in the heart. Uptake of the radioactive drug in the heart is indicative of reduced blood flow to the heart.

There is supposed that patients with functional esophageal disorders such as functional heartburns and functional chest pain have common underlying mechanisms of symptom generation. These include esophageal dysmotility, non-acidic gastro-esophageal reflux, duodeno-gastro-esophageal reflux, esophageal hypersensitivity, and psychological comorbidity. The treatment of these patients is the growing challenge in the primary care medicine and in the gastroenterological practice. It was postulated that functional disorders of the esophagus are the main reason for PPI failure in patients with heartburn. The aim of the study is to evaluate the role of biofeedback in the treatment of patients with functional chest pain and functional heartburns.

To compare computed tomography (CT) images (pictures) of the coronary arteries using the General Electric (GE) LightSpeed VCT scanner with x-ray coronary angiography in patients with typical or atypical chest pain suspected of coronary artery disease (CAD).
