Active clinical trials for "Chest Pain"

Study of diagnostic tests for heart attack for patients with chest pain.

This study is a prospective, diagnostic, cohort study within the standard care of acute coronary syndrome (ACS) patients. It compares the analytical performance of Siemens® point-of-care high sensitive troponin I testing in venous, plasma and capillary sample types. The investigators hypothesize that there is a good correlation between the Siemens® POC HS cTnI assay results for the three sample types and that the bias between different POC sample types reduces from ~10% to ≤ 5% when using heparinized transfer device for the capillary sample.

The purpose of this study is to compare different methods of collecting the amount of radiation exposure patients receive in a clinical study. As part of the PROMISE study, the Duke Clinical Research Institute Outcomes and Follow-up Group will be contacting patients every six months to ask if they had any heart procedures or testing. This information will be used to estimate the amount of radiation that they may have received from heart testing being studied in this study, PROMISE-SAFER. Patients will be asked to collect information about each heart testing they receive during the time that they are enrolled in the PROMISE study. At the conclusion of the study, we will be able to determine which method was most accurate in collecting the amount of radiation exposure for this clinical study. Through this study we hope to develop an improved methodology to estimate cumulative radiation exposure from cardiac imaging. Comprehensive measurement of cumulative radiation exposure to patients may be critically important to minimize potential harm in future studies and in clinical practice.

Compared 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.

Chest pain is an alarming symptom and one of the most frequent causes of access to the Emergency Departement. Although chest X-ray remains an essential step in the diagnostic process, several studies showed numerous limitations of radiography which frequently is inconclusive. Ultrasonography is a non-radiating imaging technique. Albeit a wide use of ultrasound, the utilization of ultrasound in the study of the lung has only recently been introduced in the clinical practice. Several studies proved that lung ultrasound is useful in the diagnosis of lung consolidation in community acquired pneumonia. Nowadays, ultrasound is not routinely used in the presence of chest pain. Our hypothesis based on clinical experience is that, in patients with pleuritic chest pain, lung ultrasound is very sensitive in detecting pneumonia and other lung diseases (such as pneumothorax) thus performing better than radiography. The primary aim of this study is to verify, in patients affected by pleuritic chest pain, the accuracy of lung ultrasound compared to chest-X-ray. The secondary aim is to evaluate the accuracy of lung ultrasound consolidations in distinguishing lung consolidation in pneumonia, atelectasis, pulmonary infarction, or tumors.

The purpose of this study is to evaluate whether new novel markers from the clinical electrocardiogram (EKG), which have been used as non-invasive measures of heart disease, can detect coronary artery disease in patients with chest pain. The researchers are especially interested in studying how changes in these unique waves evolve over time with rest and activity. It is hoped that the findings will be helpful in differentiating patients with cardiac chest pain at emergency departments from those with non-cardiac chest pain, as early identification can accelerate treatment and save lives. Eligible participants are those age 18 and older who have been referred for a nuclear stress test at University of Pittsburgh Medical Center Presbyterian Hospital to rule out coronary artery disease as part of their clinical care.

The aim of this observational study is twofold. The primary hypothesis being tested is that initial(first) high sensitivity Tn <5ng/l (limit of detection) combined with an ECG with no ischaemic changes is superior as an accelerated diagnostic tool/strategy compared to TIMI score (<2), GRACE <75 and HEART score ≤ 3. (Hs tn T- Roche elecsys HS tn T) and also against HS troponin at the 99th percentile (<15ng/l with nonischaemic changes)- again all scored with initial (first tn ) only. The second aim is to directly compare the three established methods of risk stratifying patients (predicting risk in suspected heart attacks) namely, the Global Registry of Acute Coronary Events (GRACE), Thrombolysis in Myocardial Infarction (TIMI) and HEART score in the era of high sensitivity troponins performs best.

The goal of this retrospective study is to describe emergency relevant illnesses occurring in airline passengers.

The causes of pediatric pain are often not the same for every child. Most children who visit a cardiology specialist with complaints of chest or other somatic pain have no known medical diagnosis to explain their symptoms. These children and their families often leave with no explanation for the child's distress. This early study will ask parents and children specific questions related to the stress in their lives, their emotional well-being and the children's physical functioning. The investigators want children who experience chest and other somatic pain, and those who do not, to be in their study so that they can look at both groups. The investigators hope to use these answers to better inform cardiologists who often work with children with non-cardiac pain and, in turn, help them to better serve their patients. Ultimately, the investigators hope that the answers they get will provide answers to these families. They also hope to use the results of this study to put together a short screener for the cardiologist to give to pediatric patients with complaints of chest or other somatic pain to help the cardiologists better understand their patients' symptoms.

Chest pain is a very common reason for resorting to the call center. The etiologies are very varied, ranging from benign pathologies to some that may involve, in the short term, the vital prognosis such as Acute Coronary Syndrome (ACS). ACS is a partial or complete occlusion of a coronary artery that causes potentially irreversible myocardial pain unless prompt treatment is undertaken. ACS represents 120 000 cases per year in France and causes about 18 000 deaths. There is currently no support score for the assessment of chest pain. However, reducing the duration of management of ACS is essential in order to hope to reduce the associated morbidity and mortality. In 2016, SAMU45's team established a predictive ACS score for the assessement of chest pain in SAMU 45 (France) based on the prospective study of 1367 patients. Seven items significantly associated with this risk of ACS could be highlighted: age, sex, smoking, typicality (potentially constrictive chest pain radiating potentially to the shoulders and / or jaw) pain, inaugural character of pain (ie first episode of this type), presence of sweats and the physician's belief to be in the presence of an ACS. These seven variables make up the SCARE score. This had good internal discrimination (AUC at 0.81) and excellent calibration ("p" of Hosmer-Lemeshow at 0.74). This score makes it possible to stratify the risk of ACS, by using epidemiological elements but also the physician's belief, whose Negative Predictive Value (VPN) proved excellent. The objective of this new project is to confirm by an external validation via a multicentric study the robustness of this score and thus be able to consider its use in front of any chest pain regulated in France by a call center.
