Active clinical trials for "Chest Pain"

Ischemic Heart Disease (IHD) is a condition of recurring chest pain or discomfort that occurs when a part of the heart is not receiving sufficient blood flow. It is a major public health concern internationally and in Singapore, the leading cause of death from cardiovascular disease. Cardiovascular magnetic resonance (CMR) has the ability to assess heart structures, scarring or lack of blood supply to the heart muscle with great accuracy and without any radiation involved. A CMR-compatible cycle ergometer can offer a safe and low cost stress equipment to assess heart function and motion abnormalities, and restrictions of the blood supply to the heart tissues due to partial or complete blockages of the blood vessels. This study aims to develop an exercise-CMR stress protocol by testing its feasibility and robustness in assessing changes in cardiac volumes and function due to physical exertion in healthy individuals and to assess the accuracy of the multiparametric stress-CMR as a diagnostic tool for ischemic-causing coronary artery disease (CAD) with coronary fractional flow reserve (FFR) as a reference. to measure the overall economic impact of ischaemic heart disease by estimating the direct and indirect medical costs for each participant. The current sample costs will be extrapolated to estimate the annual costs of treating and managing ischaemic heart disease in the local population. to evaluate the effects of coronary microvascular dysfunction on coronary flow and regulation, physiological response and cardiac sympathetic signaling in patients with chest pain.

The goal of this observational study is to develop a decision support system in patients presenting with chest pain in the prehospital setting. The main question it aims to answer is: • Performance of a machine learning based model for decision support of patients in contact with emergency medical services due to chest pain Participants will be asked to: respond to questions asked by the clinician at the scene regarding previous known risk factors and pain characteristics consent to the collection of routinely available data from medical records consent of taking one blood sample capillary or venous (if perifer catheter is placed for standard care reasons) troponin and glucose which is measured at the scene, disposed, and the result is entered in the clinical report form.

The goal of this clinical trial is to test mindfulness practices in children with idiopathic chest pain, which is chest pain that does not have a known cause. The main question this study aims to answer is whether children who experience idiopathic chest pain are able to follow a mindfulness program. This study also aims to determine whether mindfulness affects the way children with idiopathic chest pain cope, and if it affects their stress levels, quality of life, frequency of chest pain episodes, and chest pain intensity. Participants will: Complete a survey at the beginning of the study that asks questions about their sex, ethnicity, and history of chest pain and other chronic pains. Complete a short survey every day for the entirety of the study that asks about the number, intensity, and duration of chest pain episodes experienced that day. Complete 4 surveys, 2 weeks after they have been enrolled in the study: pain coping survey, perceived stress survey, quality of life survey, and mindfulness survey. Be randomly placed into either the control group or the mindfulness-based intervention group, 2 weeks after they have been enrolled in the study. Receive the standard of care for children with idiopathic chest pain, if they are placed into the control group. Use the mobile app Headspace to complete daily mindfulness sessions for the remaining 30 days of the study (starting after the initial 2 week period), if they are placed in the mindfulness-based intervention group. Complete 4 surveys at the end of the study: pain coping survey, perceived stress survey, quality of life survey, and mindfulness survey. Complete a mindfulness program evaluation survey at the end of the study, only if they are in the mindfulness-based intervention group. Researchers will collect information from Headspace to see how well participants in the mindfulness-based intervention group are able to follow the mindfulness program. This will help guide future, larger studies that look at the effects of mindfulness-based interventions in children with idiopathic chest pain. Researchers will also compare survey results between the control group and the mindfulness-based intervention group to see if the mindfulness program affects the way children with idiopathic chest pain cope, as well as their stress levels, quality of life, frequency of chest pain episodes, and chest pain intensity.

Most patients presenting to hospital with symptoms of a heart attack are sent home without further tests once a heart attack has been ruled out. Current strategies to assess patients with a suspected heart attack involve blood tests to measure troponin, a protein released into the bloodstream when the heart muscle is damaged. Despite having had a heart attack ruled-out, some patients have unrecognised heart disease and are at risk of having a heart attack in the future. However, clinicians do not know what is the best approach to identify and treat these patients. This study will use a heart scan known as computed tomography coronary angiogram (CTCA) to look for unrecognised heart disease in patients who have had a heart attack ruled out. In an earlier study, the Investigators performed this scan in patients referred to the outpatient cardiology clinic with stable chest pain and found that this improved the diagnosis of heart disease, leading to improvement in patient care that prevented future heart attacks. Previous research from the Investigators has also found that troponin levels below those used to diagnose a heart attack may help to identify those who are at greater risk of having a heart attack in the future. The aim of this study is to find out if patients with these low levels of troponin, where a heart attack has been ruled out, will benefit from CTCA to look for unrecognised coronary heart disease.

The Purpose of this study is to better understand changes in obstructive coronary artery disease in different organs other than the heart such as the brain and the kidneys using a new generation total body PET scanner.

This is a prospective four-site cohort study, which will accrue adults with symptoms concerning for acute coronary syndrome over a period of 12 months. After application of inclusion and exclusion criteria, Physicians will complete HEART Pathway and EDACS risk assessments on eligible participants. Major adverse cardiac events as defined by our study will be assessed at 30 days using electronic health record, telephone contact, and national death and health events search. Outcomes for all patients will then be matched against the existing pathway of care for acute chest pain that is being used currently to compare diagnostic accuracy of both scores to diagnose low risk chest pain in this population. The objective of this study is to compare the test performance of the HEART and EDACS pathway in a large cohort of patients presenting to the Emergency department with chest pain in the United Arab Emirates and to determine if either accelerated diagnostic pathway can achieve a negative predictive value of ≥99% for 30-day MACE as well as to externally validate EDACS-ADP and the HEART pathway in the UAE population and gain further insight into the applicability of these decision-making aids in different clinical settings in order to assess which score is best suitable for the UAE population. Our third objective is to compare the effectiveness of both scores to the existing framework for chest pain work up in each hospital and have the opportunity to unify Emergency Departments in their chest pain pathways in the UAE. The investigators will be testing the null hypothesis that there is no difference in using the EDACS-ADP to safely classify patients to low-risk category and early discharge from the ED versus the HEART pathway.

The PRESC1SE-MI study compares two algorithms for triage of patients presenting with chest pain and symptoms of heart attack (myocardial infarction) to the emergency department. Both algorithms are recommended by the European Society of Cardiology: the 0/3-hour algorithm and the 0/1-hour algorithm. Currently, most emergency departments worldwide use the 0/3-hour troponin algorithm. Cardiac troponin (cTn) is a heart-specific biomarker which indicates damage of the heart muscle and which increases after a heart attack. In the 0/3-hour algorithm, the amount of troponin in the bloodstream is measured with a high-sensitivity assay at admission and 3 hours thereafter. Likewise, the 0/1-hour algorithm means that the blood sample in which the troponin is measured is collected at admission and 1 hour later. Since recent clinical studies suggest that the 0/1-hour algorithm is superior to the 0/3-hour algorithm, many hospitals consider switching to the 0/1-hour algorithm. The aim of this study is to assess how feasible the time-saving 0/1-hour algorithm would be in reality and whether it provides the same accuracy and safety in the diagnosis of myocardial infarction as the current practice the 0/3-hour algorithm.

This study is an extension of a planned quality improvement project that aims to promote standard of care by increasing the use of evidence-based clinical decision rules amongst emergency medicine providers in the University of Utah Emergency Department. Patient-specific information from the EHR will be used to recommend the use of relevant clinical decision rules to emergency medicine providers at the point-of-care. These recommendations will be in the form of non-interruptive alerts with one-click access to the suggested decision rules through the MDCalc Connect EHR add-on application. Specific aims of the study are to determine if 1) patient-specific non-interruptive alerts increase the use of clinical decision rules amongst emergency medicine providers and 2) an increase in the use of clinical decision rules affects provider ordering habits.

The study will systematically evaluate how an emergency manual-a collection of checklists and fact sheets-affects the performance of resuscitation teams during the management of priority one patients in an emergency department.

Primary prevention of coronary disease and especially its major complication, inaugural myocardial infarction, is based on any prodromal symptoms identification and on risk profile establishment. About 50% of myocardial infarctions are caused by an unstable non-stenosing plaque, asymptomatic before the event since without significant reduction in coronary flow, particularly during a stress test or during stress imaging. Study purpose is to set up, in medical emergency department, check-up unit and cardiology department, a primary prevention strategy articulated around a routine examination: calcium scoring. The latter makes it possible to categorize patients according to their risk of generating atheromatous plaques and to classify them into several risk levels (groups) according to their score: low (<40th percentile), intermediate (between the 40th percentile and the 65th percentile: group III) or high risk (>65th percentile, group IV). 18F-Na PET scan can mark unstable coronary plaques. For the intermediate risk population who would demonstrate within 6 to 18 months after first calcium score either an increase of percentile of more than 20% or an increase above 20 points of the calcium score and for high risk population, 18F-Na PET scan will be recommended and repeated 6 months later. Secondary prevention treatment will then be administered in the event of an abnormal examination.
