NCT07536932
The goal of this prospective multicenter observational study is to learn whether an artificial intelligence model based on electrocardiograms (ECGs) can help diagnose acute type A aortic dissection (TAAD) in adults who come to the emergency department with chest pain or related symptoms. The main question it aims to answer is: Can the AI-ECG model accurately distinguish TAAD from other causes of chest pain in a real-world emergency setting? Researchers will compare the AI model's ECG-based predictions with the final diagnosis confirmed by computed tomographic angiography (CTA), which is the reference standard. Participants will undergo routine emergency ECG testing and subsequent diagnostic evaluation as part of standard care. Clinical and ECG data will be collected from five tertiary hospitals, and the model's diagnostic performance will be assessed across centers.
NCT05897632
The goal of this study is to determine if rapid outpatient evaluation vs hospitalization management is the best strategy (based on patient-centered measures and safe, equitable, and efficient resource use) for evaluating patients with acute chest pain who are at moderate risk for acute coronary syndrome (ACS). Patients will be randomized in the Emergency Department to either an outpatient evaluation (CARE-CP) or hospitalization evaluation for their symptoms.
NCT07432620
The goal of this observational study is to learn whether combining stress echocardiography (stress echo) results with routine clinical information can better predict important heart outcomes in adults (18+) with chest pain who were assessed for suspected coronary artery disease. The main questions it aims to answer are: Can an artificial intelligence / machine learning model using stress echo findings plus clinical factors (such as blood pressure, diabetes, smoking, other health conditions, medications, and body measurements) predict major heart-related events (such as heart attack, stroke, death related to heart disease, or the need for coronary procedures) more accurately than stress echo results alone? Can the model help identify which patients are most likely to benefit from further invasive assessment and possible coronary revascularisation (for example, a stent or bypass surgery)? Which combination of stress echo measurements and clinical factors contributes most to risk prediction? Participants will: Not be asked to attend extra visits or have additional tests for this study. Have their existing stress echo reports and routinely collected hospital record data analysed (approximately 3,000 people who previously had dobutamine stress echo at Milton Keynes University Hospital). In some cases, if outcomes are not fully available from hospital records, the research team may check additional sources (such as GP records, or contacting the patient if appropriate) to confirm whether a major heart-related event occurred.
NCT05809648
The purpose of the research is to see if patients that come to the Emergency Department with chest pain can be more accurately and more quickly diagnosed by magnetocardiography (MCG) to see if their chest pain is caused by coronary ischemia (reduced blood flow to the heart) in patients with normal or have non-specific changes on the ECG vs other causes by other reasons.
NCT06836466
This study aims to investigate physicians' awareness regarding patients presenting with potential acute ischemic chest pain. It focuses on various electrocardiogram (ECG) patterns requiring prompt catheter lab activation for reperfusion therapy alongside other ECG mimics that may lead to false catheter lab activations.
NCT06404515
The purpose of this study is to utilize an innovative healthcare delivery strategy via telehealth group counseling sessions to improve engagement, adherence, and ultimately outcomes in female patients with atherosclerotic cardiovascular disease (ASCVD).
NCT06670768
This prospective study aims to compare functional abnormalities detected using myocardial perfusion SPECT imaging (MPI SPECT) with the extent and severity of anatomical findings on coronary computed tomography angiography (coronary CTA). Additionally, the investigators aim to enhance the diagnostic value of MPI SPECT by quantifying myocardial blood flow and utilizing myocardial flow reserve calculated from dynamic SPECT images. 50 patients with suspected coronary artery disease are anticipated to be enrolled. Pharmacological stress and rest-phase dynamic and static MPI SPECT following an additional coronary CTA scan are to be performed. The obtained multimodality imaging data (functional and anatomical parameters) are planned to be compared and subjected to statistical analysis. The results of this study are expected to improve risk assessment for patients with moderate cardiovascular risk and enhance the diagnostic performance of MPI SPECT.
NCT06925568
This study aims to understand how patients with acute chest pain are evaluated, treated, and cared for in emergency departments (EDs) at regional hospitals in Tanzania. Chest pain can be caused by many conditions, some of which are life-threatening, like heart attacks (acute coronary syndrome, or ACS). In Tanzania and other low-resource settings, delays in diagnosis and treatment can lead to poor outcomes. This study will document current practices, identify challenges, and link these findings to patient outcomes (e.g., survival, complications) to improve care for future patients. \- Participants: Adults (18 years or older) who come to the ED with chest pain or suspected acute coronary syndrome (heart problem) at the regional referral hospitals in Dar es Salaam, Tanzania. Three regional referral hospitals and one specialized cardiac hospital (Jakaya Kikwete Cardiac Institute) will be involved in this study. Research assistants will collect data during routine care. During the study, i. Enrollment will take place over 12 months; 317 patients with chest pain will be invited to participate. ii. Researchers will record: * How quickly patients receive initial diagnostic tests (e.g., ECG, blood tests for heart damage). * Treatments given (e.g., medications, procedures to restore blood flow to the heart). * Patient outcomes over 30 days (e.g., survival, readmission to the hospital, complications like another heart attack or stroke). iii. Follow-up: Patients will be contacted by phone 30 days after their ED visit to check their health status. This study is important because-: Chest pain is a common reason for ED visits, but in Tanzania, many patients face delays in diagnosis or lack access to lifesaving treatments. This study will identify gaps in care to help hospitals improve emergency services. Understanding the challenges in chest pain care can empower families to advocate for timely treatment for their loved ones. For Healthcare Providers: The findings will guide hospitals in adopting better protocols (e.g., faster ECGs, improved use of medications) and allocating resources effectively. For Policymakers: Results can inform national strategies to reduce deaths from heart disease in Tanzania. During the study, participants should know that there will be no changes to care; patients will receive the same care they would normally get. The study only observes and records what happens. Personal information will be kept confidential, and data will be anonymized (no names or identifiers used). Participation is voluntary, and patients can choose to join or refuse without affecting their care. Key Questions the Study Will Answer 1. How quickly do patients with chest pain get critical tests (like ECGs) and treatments in Tanzanian hospitals? 2. What are the most common barriers to timely care (e.g., lack of equipment, training gaps)? 3. What percentage of patients survive 30 days after a chest pain episode, and what factors influence their outcomes? Potential Benefits * Improved Care: Findings may lead to better hospital protocols. * Resource Allocation: Highlight where hospitals need more tools (e.g., ECG machines) or medications * Global Impact: Lessons from Tanzania can help other low-resource countries improve emergency heart care. Ethical Considerations * Approval: The study has been reviewed and approved by ethics committees to ensure patient safety and rights. * Informed Consent: Participants (or their families, if critically ill) will be asked for permission before joining. How will results be shared-: Findings will be published in medical journals and shared with Tanzanian hospitals, health officials, and global organizations to drive improvements in emergency care.
NCT03439449
The aim is to determine the additional value of computerized, patient-entered medical histories for the management of patients presenting at the emergency department with chest pain.
NCT06670027
This study will be used to compare the effects of two auditory stimulation methods on improving vital signs parameters, reducing the severity of chest pain, and improving the sleep quality of cardiac patients.
NCT06718374
Cardiovascular disease is the most severe cause of death among all non-infectious diseases and accountable for 17.5 million deaths in the world. Heart mortality in patients with DM is frequently associated with prevalence silent ischemia, which is triggered by autonomic neuropathy, thereby decreasing the chest pain felt by them
NCT06669884
Chest pain accounts for 10-20 percent of all emergency department visits. The stratification of chest pain is always a challenge. Electrocardiograms (ECG) have been used in clinical practice for 100 years, which is too important to be replaced due to its advantages of non-invasive, simple, rapid and inexpensive. ECG contains numerous signals derived from depolarization and repolarization of cardiomyocytes. However, the interpretation of ECG hasn't improved much in a hundred years. Based on determine-learning, Cong W's team developed an technique called "cardiodynamicsgram (CDG)", which is an outstanding method to identify myocardial ischemia. This study will further investigate the accuracy of CDG in stratification of patients with chest pain in Emergency department.
NCT05752188
The role of the sST2 biomarker has been widely explored in heart failure, so much so that it was included in the AHA guidelines in 2013 and 2017. Recently, several studies are proposing a role of sST2 in the prognostic stratification of patients with Acute Coronary Syndrome and ischemic heart disease, in association with other biomarkers even proposing a possible therapeutic differentiation. The combined use of sST2 with high-sensitivity troponins could be a promising strategy to identify those patients who, despite having early rule-out after evaluation at the Emergency Department, have a higher risk of onset of cardiovascular events in the medium-long term.
NCT05174247
Rationale: Patients with stable chest pain enter a diagnostic pathway where Coronary Computed Tomography Angiography (CCTA) is often the first line non-invasive test to detect coronary stenosis. An anatomically significant (≥ 50% luminal narrowing) stenosis on CCTA does however not always cause cardiac ischemia (i.e. hemodynamically significant stenosis). CCTA is often followed by invasive coronary angiography (ICA) to assess the hemodynamic significance of the stenosis which is the key determinant to decide on treatment (revascularization by coronary stenting or surgery). CCTA has a very high negative predictive value but the positive predictive value is moderate. Hence, anatomically significant stenoses on CCTA often turn out not to be hemodynamically significant on ICA. Fractional Flow Reserve from coronary computed tomography (FFRct) analysis is a new non-invasive technique that uses the CCTA images as a basis for complex software based calculations and modelling to provide additional functional information based on the anatomical CCTA images. Thus, FFRct is a totally non-invasive method. Adding the FFRct analysis to the anatomical assessment of CCTA is expected to reduce the number of patients being referred to ICA where no signs of hemodynamically significant stenosis are found on ICA.
NCT06255769
This is a prospective clinical study aiming to investigate the efficacy of Magnetocardiography (MCG) in detecting myocardial ischemia in patients of a suspected non-ST-elevation-acute coronary syndrome (NSTE-ACS) by using Single photon emission computed tomography (SPECT) as the gold standard for determining the presence and severity of myocardial ischemia.
NCT04748237
The aim is to determine whether a diagnostic strategy including early coronary computed tomographic angiography in intermediate-risk patients presenting to the Emergency Department with chest pain reduces the composite endpoint of death, readmission because of myocardial infarction or unstable angina requiring revascularization.
NCT06520150
Our study consists of a combination of regional blockade ('local' anesthesia) of the anterior and lateral chest wall in the form of a thin needle prick and the supply of local anesthetic drugs to the area of the relevant chest wall structures to exclude all stimuli, including pain from the operative site. A short-acting analgesic and sedative drug will be administered intravenously throughout the procedure - in a dose that allows the required contact between the patient and the anesthetist. If necessary, the dose of the drug may be increased to maintain pain comfort throughout the procedure. The anesthetic team will be with the patient throughout the procedure to ensure comfort and safety.
NCT06507995
The primary objective was to evaluate the effectiveness of thoracic interlaminar epidural injections in alleviating pain and enhancing function in patients suffering from chronic mid and/or upper back pain. Materials and Methods One hundred patients were randomly divided into two groups, each consisting of 50 patients. Group I received only a local anesthetic, while Group II received a combination of local anesthetic and steroids. The random assignment to either Group I or Group II was determined using a simple computer-generated sequence. Outcomes were evaluated using the Numeric Rating Scale (NRS) and the revised Oswestry Disability Index (rODI). Patients who showed significant improvement for more than four weeks after the first two procedures were deemed successful. Those who did not were classified as failed participants. Significant improvement was defined as a reduction of more than 50% in both NRS and rODI scores, with assessments conducted at baseline and at 3, 6, and 12 months post-treatment. The center where the study was conducted: Ankara University, Faculty of Medicine, Department of Anesthesiology and Reanimation, Division of Algology, Ankara, Turkey

This study will evaluate the accuracy and efficiency of large language model in emergency triage.
NCT05748691
Cardiac troponin is central to the diagnosis of myocardial infarction and high-sensitivity cardiac troponin (hs-cTn) assays are the preferred choice for the assessment of patients with suspected acute coronary syndrome. Since the introduction of hs-cTn assays in Europe in 2010, most hospitals have switched from contemporary sensitive cardiac troponin assays to a hs-cTn assay. The implementation of hs-cTn assays has led to an increase in the number of patients identified with myocardial injury. Although both hs-cTnI and hs-cTnT assays are recommended in current guidelines, the impact of switching from a hs-cTnI assay to a hs-cTnT assay on clinical practice is unknown. At this point, no studies have evaluated the impact of implementing sex-specific hs-cTnT thresholds on the diagnosis of myocardial infarction and outcome in clinical practice. The investigators propose to determine the proportion of patients with and without myocardial injury admitted to the hospital before and after implementation of a hs-cTnT assay and to evaluate the impact on investigations, care and clinical outcomes in consecutive patients with suspected acute coronary syndrome.
