Active clinical trials for "Chest Pain"

This research asks whether coronary calcium scoring, a non-invasive test based on computed tomography scanning, is a better way to diagnose chest pain patients than other currently used methods. Three of four patients will undergo calcium scoring and the remaining patients will receive standard care.

The purpose of this registry is to assess and improve the process of care and health outcomes of patients presenting to the Emergency Department with chest pain suspected to be of cardiac origin. The study will identify which methods facilitate the diagnosis and risk stratification of ST elevation myocardial infarction (STEMI) or non STEMI, including patients with occult myocardial infarction (MI), and result in a shorter time to definitive diagnosis and treatment.

The main aim of the WESTCOR study is to investigate the ability of two high sensitive cardiac troponin (hs-cTn) assays to diagnose acute coronary syndrome and predict prognosis in different patient populations (e.g. gender, age and co-morbidity) to validate the suggested 1 hour protocol for rule in and rule out of acute coronary syndrome for two hs-cTn assays in an unselected chest pain population to investigate different biomarkers ability to predict long term prognosis after hospitalization for chest pain

Dyspnea and chest pain represent 1.5% of general practice consultations. They may be a sign of many diseases, potentially serious. The concept of Gut Feelings brings a sense of alarm and reinsurance. The sense of alarm reflects a sense of mistrust about the patient's clinical situation, in the absence of objective argument. The sense of reinsurance reflects a sense of confidence about the patient's situation, in the absence of objective argument. Gut Feelings plays a key role in the diagnostic reasoning in general practice. A questionnaire measuring the Gut Feelings was validated in French after a linguistic validation procedure.

Noncardiac chest pain (NCCP) is a common clinical problem worldwide. In Hong Kong, it has been estimated that about 20% of patients with chest pain are misdiagnosed to have coronary heart disease. Despite its benign nature, this condition causes anxiety, impairs quality of life and consumes a substantial amount of healthcare resources. While acid reflux and motility disorder in the esophagus are often attributed as the cause of NCCP, visceral hyperalgesia of esophagus is now recognized to play a central role in the pathogenesis of this condition. This research project aims to evaluate the role of visceral hyperalgesia in Chinese patients with NCCP. NCCP patients will be evaluated for the prevalence of gastroesophageal reflux disease and esophageal motility disorder by endoscopy, manometry and pH study. The visceral sensory and pain thresholds of these patients will be compared with asymptomatic controls.

High Resolution Manometry is a new technology that utilizes 36 solid state sensors on a thin catheter spaced at 1-cm intervals. One can more effectively measure the pressure of the esophagus. It includes a sophisticated software to display the pressures data as color topography plot using time, length of the esophagus and pressure within the entire esophagus. It is unclear if this technology improvement actually correlates with patient's symptoms.

This study is designed to evaluate a new approach to the diagnosis of chronic or sub-acute chest pain patients in the out-patient setting. Patients in this study are selected to be "low-risk", meaning they are not having an acute or recent heart attack (AMI), based on screening blood tests and electrocardiograms (EKGs). In addition, these patients have a low or intermediate pre-test likelihood of the coronary artery disease (CAD), which means that probability of the CAD based on the available clinical and historical information, does not make a diagnosis of the CAD a certain clinical diagnosis in the particular patient and this, in turn, requires an additional diagnostic work up.

The purpose of this research study is to evaluate a better way of diagnosing heart artery disease, heart attack and damage to the heart muscle early on. Currently, it often takes several hours after admission before lab tests will show that there has been any damage to the heart muscle. Although the standard electrocardiogram is quick and non-painful it may miss many cases of significant coronary heart disease. The investigators are proposing that a new entirely non-contact tool, the Magnetocardiograph (MCG), with high accuracy is able to predict the presence of significant coronary heart disease early on before other studies become positive. The investigators hope by this that the investigators can develop an algorithm for better triage and management of patients with chest pain. This research study is designed to test the effectiveness of the investigational use of the Magnetocardiograph (MCG) that has been approved by the U.S Food and Drug Administration (FDA). While the MCG used in the study is FDA-approved as a tool for the non-contact measurement and display of the magnetic fields of the heart generated by the electrical currents, it is not yet approved for the specific diagnosis of heart artery disease (ischemia).

During the outbreak of COVID-19, among patients with chest tightness and chest pain as the main symptoms in major medical institutions in Shanghai, China, the past medical history and rapid testing were used to quickly identify the risk stratification of the patients.

This is a retrospective study, designed to be conducted at a single-center in the US. The study will conduct a one-time data abstraction from approximately 500 patient medical charts who received Age/Sex/Gene Expression score (ASGES) also knows as Corus CAD testing, by order of the Principal Investigator. Limited demographic data and patient data pertaining to cardiology referral or advanced diagnostic testing will be collected. All data will be collected anonymously.
