Filter by:This study aims to ascertain the lived experiences of 6 patients attending a nurse-led chest pain clinic via an interview, and to understand the demographics of referred patients.
The investigator aims to determine the feasibility of understanding the process of active versus chronic calcification using Na-F PET scan and contrast CT scan of the heart. The patient cohort will consist of patients diagnosed to have either acute coronary syndrome (ACS) (comprising of either unstable angina pectoris or acute myocardial infarction) or suspected coronary artery disease (CAD). The PET images will be compared to images obtained from standard contrast CT of the coronaries. This study will provide additional insights about active versus non-active calcification amongst patients with ACS or suspected CAD.
A prospective, blinded multicenter study for evaluation of chest pain patients with severe coronary calcium (Agatston score > 399). The objective is to evaluate if an initial non-invasive strategy with coronary computed tomography angiography (CCTA) including functional flow reserve derived from CCTA (FFR-CT) is as effective as invasive coronary angiography (ICA) including functional flow reserve (FFR) for the detection and exclusion of obstructive coronary artery disease (CAD). Study hypothesis: initial non-invasive anatomic and functional testing is non-inferior to an invasive anatomic and functional testing strategy.
This is a prospective, observational study to assess the efficacy of the newly developed SVEAT scoring system in identifying low-risk patients who may be eligible for early discharge. Various elements of clinical information including Symptoms, Vascular history, EKG, Age and Troponin values will be checked and entered on the scoring form to calculate the SVEAT risk score. Additionally, HEART score and TIMI risk score will be calculated for the same subjects. The primary aim is to assess the positive and negative predictive values for the SVEAT index for cardiovascular events and compare it to the HEART and TIMI Scores.
Decision aids such as the HEART Pathway, Emergency Department Assessment of Chest Pain Score (EDACS), Revised Geneva Score and PERC Score have similar ability to accurately risk stratify Emergency Department (ED) patients with possible Acute Coronary Syndrome (ACS) and Pulmonary Embolism (PE) and have become standard practice in the ED setting. This study seeks to determine whether prehospital use of these decision aids is feasible and determine which are the most sensitive and specific for prediction of ACS and PE, respectively.
This study, sponsored by Nihon Kohden, aims to determine the sensitivity and specificity of synthesized 18-lead electrocardiogram (ECG) in the diagnosis of posterior-lateral and/or right-ventricular ischemia, using actual 18-lead ECG as the gold standard. The synthesized 18-lead ECG calculates six extra leads of information from the standard 12-lead ECG done in the Emergency Department (ED). Nihon Kohden has created synECi18 Technology, which can mathematically synthesize and display the extra leads. The patient population (n=300) will consist of patients who present to the North Shore University Hospital or Long Island Jewish Medical Center ED with a chief complaint of chest pain, chest pressure, or chest discomfort. These patients will be receiving a standard 12-lead ECG as part of their routine clinical care. Patients with ST-Elevation Myocardial Infarction (STEMI) and a known positive troponin value will be excluded from the study. Trained ED study technicians will use ECG machines provided by Nihon Kohden to obtain two consecutive 15-lead ECGs. The two 15-lead ECGs are then saved onto the ECG machine.The saved information will later be input into an algorithm to calculate the synthesized 18-leads. The actual 18-leads (composed of the two 15-leads conducted in the ED) will be compared with the synthesized 18-leads produced by the synECi18 technology. A study cardiologists will evaluate the actual 18-lead ECGs and synthesized 18-lead ECGs and determine whether there is posterior-lateral and/or right-sided ventricular ischemia. The cardiologists will be blinded to the type of waveform they are analyzing (synthesized versus actual). The study will not interfere with patient care or treatment, however, the two 15-lead ECGs done in the ED will be shown to the physician who can determine whether or not to order an official 18-lead ECG in the hospital's electronic medical record system. It is hypothesized that the synECi18 synthesized 18-lead ECGs will provide high sensitivity and specificity for diagnosing posterior-lateral and/or right-ventricular ischemia, with the actual 18-lead ECGs being used as the reference for comparison.
Chest pain is a common presenting complaint at the Emergency Department (ED). Many of these patients undergo lengthy assessments in the ED or are admitted which contributes to ED and hospital crowding as well as a substantial health care burden. The now commonly used high-sensitivity cardiac troponin assays enable faster rule-out of acute myocardial infarction (AMI). The European Society of Cardiology (ESC) recommend the use of a 0h/1h high-sensitivity cardiac troponin T (hs-cTnT) protocol, but all studies so far have been observational. The safety and effectiveness of the protocol when implemented in routine care is thus unknown. The aim of this study is to determine the safety and effectiveness of the ESC 0h/1h hs-cTnT protocol, supplemented with clinical assessment and ECG, when implemented in routine care.
Prospective, single center, single arm pilot study evaluating the feasibility of delivering remote ischemic conditioning (RIC) by emergency medical services (EMS) in the prehospital setting. Eligible patients will have chest pain or anginal equivalent symptoms and require ground ambulance transport to the hospital. All subjects will undergo the standard RIC procedure (i.e., up to four cycles of alternating 5-min inflation and 5-min deflation) with the autoRIC® device (CellAegis Devices, Inc., Toronto, Ontario). The primary objective is to evaluate the number of cycles of RIC completed in patients having the procedure initiated by EMS in the prehospital setting.
This Emergency Department based study investigates the feasibility and effectiveness of a mindfulness based stress reduction (MBSR) training program referral for patients with chest pain at low risk for acute coronary syndrome but associated with anxiety. Outcomes assessed for eligible patients randomized to MBSR vs. usual care include mental health (longitudinal Generalized Anxiety Disorder - 7 (GAD-7) scores), quality of life (PROMIS Global Short Form), and ED resource utilization (return Emergency Department (ED) visits).
Non-cardiac chest pain (NCCP) is common and has substantial impact on patients' psychological wellbeing, quality of life and healthcare use. Although cardiac diagnosis is 'ruled out', many patients think they have an undetected cardiac disease (i.e. they suffer cardiac anxiety) as no other explanation is offered. They therefore avoid activities that they believe might be harmful to their heart, leading to greater ill-health, and increased healthcare use and societal costs. Targeting cardiac anxiety with psychological interventions might break this vicious circle and improve patient outcomes. Patients need to evaluate the way they perceive and handle their chest pain, which can be done with cognitive behavioral therapy (CBT). The aim of this study is therefore to evaluate the short- and long-term effects of an Internet-delivered CBT (I-CBT) program on psychological distress and other patient-reported outcomes in patients with NCCP. A second aim is to explore factors related to implementation of I-CBT in clinical care. The study has a randomized controlled design comparing I-CBT with Internet-delivered information program. Quantitative methods will be used to evaluate the effectiveness of the I-CBT program. Implementation issues will be evaluated from the perspectives of patients, healthcare professionals and policymakers using qualitative methods.
