27 Clinical Trials for Various Conditions
The objective of the present study is to establish the safety and efficacy of Prochymal® following first acute myocardial infarction.
The purpose of this study is to demonstrate the benefit of bivalirudin in combination with clopidogrel with provisional GPIIb/IIIa inhibitor use, in reducing the bleeding complications associated with early invasive management of patients presenting with an ST Elevation Myocardial Infarction (STEMI) and undergoing primary PCI, while providing similar rates of ischemic events when compared to published results of relevant trials.
The purpose of this study is to collect real-world data on the TherOx DownStream System® to assess the effectiveness and cost- effectiveness of SSO2 Therapy, compared with PCI alone for treatment of patients with acute anterior MI.
Given the existing controversy regarding the appropriate determination time for placement of implantable cardioverter-defibrillator (ICD) in patients at risk for sudden cardiac death (SCD) following acute myocardial infarction (AMI), the modest ability of current criteria to determine which patients will experience SCD, and the high impact of SCD to society, we propose to conduct a prospective non-randomized observational study to determine: * Whether quantification of left ventricular (LV) scar volume by cardiac magnetic resonance (CMRI) prior to hospital discharge helps to predict which patients will have a low ejection fraction (35%) at follow up and qualify for ICD implantation. * Whether quantification of infarct scar volume by CMRI will help to identify which patients will experience malignant ventricular arrhythmias and/or SCD at follow-up, independent of the LV ejection fraction (LVEF). Primary hypothesis: Percentage of left ventricular scar volume as measured by CMRI post-MI strongly correlates with LVEF at 40 days and 3 months. Secondary hypothesis: 1. A volume of \>40% of left ventricular scar measured by CMRI post-MI is predictive of LVEF less than 35% at 40 days and at 3 months 2. Volume scar as measured by Cardiac magnetic resonance imaging after AMI (at day 5) is predictive of clinical outcomes: SCD, total mortality, heart failure admission and life-threatening malignant ventricular arrhythmias regardless of ejection fraction at 40 days and at 3 months. Safety hypothesis: ICDs will be implanted if patients meet criteria at 40 days post MI as per the current American College of Cardiology (ACC) /American Heart Association (AHA) /Heart Rhythm Society (HRS) 2008 Guidelines for Device-Based Therapy of Cardiac Rhythm Abnormalities
This pilot feasibility study will test whether a home-based cardiac rehabilitation intervention, using physical therapist visits combined with mobile health technology, will prevent decline in high-risk patients post acute myocardial infarction (AMI). Participants will be randomized to either an intervention arm (home-based physical therapy), or a control (usual care) arm. Prior to discharge, participants in the intervention arm will receive a 1-hour educational session by a research physical therapist that includes information on cardiac risk factor management, postoperative recovery, education on medication adherence, and a prescription for home exercise that is tailored to each patient's baseline abilities and limitations. Participants assigned to the control arm will receive a 30-minute counseling session on risk factor modification prior to discharge, in addition to usual care post-AMI.
The overall objectives of this study are to improve medication adherence of patients and subsequent health outcomes. This study is designed to examine the existence of strong associations between social networks and health behavior. This study intends to demonstrate that social forces are particularly effective at building enduring habits for healthy behavior, specifically adherence to statin medication for this study. The investigators believe the improved medication adherence will result in fewer additional vascular events, following the most recent of these events, and will result in fewer patient hospitalizations. The investigators will leverage insights from the fields of social comparison (being provided with information about the actions of others prompts social comparison that can significantly influence behavior), social pressures (encouragement or discouragement from others is a powerful social force that can influence individual behavior), and social triggers (cues in the environment can motivate people to take certain actions and have powerful effects on purchasing behavior). The results of this study and experience gained from the implementation of these interventions will be used to inform new versions of a larger trial intervention to be tested in new patient cohorts in a rapid cycle framework.
Subjects with anterior acute STEMI who receive an IABC before primary PCI will have decreased MI size.
A prospective, randomized multicenter study of subjects with a high-risk of having a myocardial infarction (MI) due to acute coronary syndrome or bypass surgery. There is no differential intervention administered to the two arms of the ALERTS Study. The study evaluates whether or not a patient alarm from the Guardian System will provide benefit (e.g. shorten pre-hospital delay) compared to symptoms-only ER presentation in the event of a heart attack. An amendment to the data analysis protocol was collaboratively created by AngelMed and FDA, and was adopted by AngelMed on 4/22/2017.
The primary goal of this study is to evaluate the effectiveness of direct-to-patient mailings designed to increase patient's adherence to prescribed beta-blockers following an acute myocardial infarction (AMI). Prior to developing patient materials, focus groups were conducted with patient who had previously suffered an acute myocardial infarction (AMI) to identify the issues and information that patients felt were important to include in our materials as well as the best way to present the information. Additionally, patient materials were "pre-tested" with AMI patients to ensure that the materials were clear and easy to read and that the key messages were understood.
The research study is being done to see if ziltivekimab can be used to treat people who were admitted to hospital because of a heart attack. Ziltivekimab might reduce development of heart disease, thereby preventing new heart attacks or strokes. Participants will either get ziltivekimab (active medicine) or placebo (a dummy medicine which has no effect on the body). Which treatment participants get is decided by chance. The chance of getting ziltivekimab or placebo is the same. The participant will need to inject the study medicine into a flat skin surface in there stomach, thigh, or upper arm once every month. Ziltivekimab is not yet approved in any country or region in the world. It is a new medicine that doctors cannot prescribe. The study will last for about 2 years.
The objective of this protocol is to use established standard criteria and methods for the collection of hMSC (human mesenchymal stromal cells) from healthy bone marrow donors. The hMSC collected from the donors will use to develop well-defined and reproducible cell banks. Standard manufacturing procedures and quality control testing methods will be used to characterize and evaluate the final cell product. After the cell banks are created, these cell products will be used in future translational or clinical research.
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.
The goal of this proposal is to test the implementation of an innovative approach to improving health and lowering cost for a high risk population of patients with acute myocardial infarction (AMI) immediately post-hospitalization. The investigators will implement a new service delivery approach that will provide a foundation for a payment system that rewards keeping high-risk patients healthy and that deploys technology and a health care workforce of the future to implement prevention, care coordination, care process re-engineering, team-based care, and the use of data to support new care delivery models. This program is focused on coronary artery disease (CAD), but we expect that a successful implementation of this model will demonstrate a sustainable pathway to the three-part aim not just for CAD, but for many other conditions whose outcomes are highly sensitive to post-discharge coordination. This proposal has three main principles: 1. Principles of behavioral economics that have been developed, refined, and tested over the past decade offer practical insights into health behaviors that were previously unavailable and are not reflected in existing care models. 2. New technology, typically wireless devices for pill bottles, and mobile telephones, make engagement with patients substantially easier and more immediate now than ever before. 3. While randomized clinical intervention trials provide exceptional confidence of comparative effectiveness in narrow interventions, they are slow and rigid and dont reflect the urgency that health care transformation currently requires. Principles of rapid cycle innovation are gaining acceptance as an alternative to or supplement of these traditional methods in supporting evidence for implementation success.
In the setting of reperfusion therapy in an acute myocardial infarction using primary percutaneous intervention (PCI), the body's own inflammatory system involving the complement cascade may be harmful. This study will test the safety and efficacy of a novel complement inhibitor, pexelizumab to reduce mortality at 30 days.
The observational study titled "Observational Assessment of Support with Impella Best Practices in Acute Myocardial Infarction Complicated by Cardiogenic Shock (OASIS-AMICS)" aims to evaluate the safety outcomes of patients with acute myocardial infarction complicated by cardiogenic shock (AMICS) who receive Impella CP during percutaneous coronary intervention (PCI) and who are managed with Impella best practices while receiving guideline-directed standard of care. This prospective, multicenter study will enroll up to 250 hemodynamically unstable patients with cardiogenic shock of less than 12 hours duration and acute myocardial infarction (AMI) of less than 24 hours duration. Cardiogenic shock will be confirmed by tissue hypoperfusion (lactate ≥ 2.5mmol/L and/or SvO2 \<55% with a normal PaO2) and systolic blood pressure \<100 mmHg and/or need for vasopressor therapy (dopamine/norepinepherine or epinephrine). Patients will be assessed for various safety endpoints, including a composite safety endpoint involving major bleeding, acute limb ischemia, and acute kidney injury. Secondary endpoints will evaluate all-cause mortality, major adverse cardiovascular and cerebrovascular events (MACCE), and hospitalizations through 1-year post-Impella implant. All patients presenting with AMICS at study sites will be screened for inclusion in the study after hospital discharge (or after death, if prior to hospital discharge). IRB approved consent waiver will be used to collect data from electronic health records from; Impella placement to discharge and post-discharge at 30 days post-Impella implant, 6 months post-Impella implant, and 1 year post-Impella implant.
This is a double-blind, sham-controlled clinical study to evaluate the safety and feasibility of AMI MultiStem therapy in subjects who have had a heart attack (Non-ST elevation MI).
SILVER-AMI is a research study of older persons who are admitted to the hospital with a heart attack. Patients will be interviewed in the hospital and again 6 months later. The researchers will also collect detailed medical record information to understand the effect of heart attacks on older persons. The research team at Yale University will use this information to develop a risk model that can be used to help doctors predict recovery. The goal of the study is to help older people in the future make well-informed decisions about their health care during a heart attack.
Background: * INFUSE AMI is an ongoing clinical trial examining how patients with heart attacks are treated. The study's aim is to help determine the best way to treat patients with specific kinds of heart attacks caused by blood clots. * To evaluate the effect of the heart attack on the heart tissue and function, participants in the INFUSE-AMI study will have magnetic resonance imaging (MRI) scans of the heart at specific times after their heart attack. Objectives: - To perform cardiac MRI scans on patients who are participating in the INFUSE-AMI study. Eligibility: - Individuals at least 18 years of age who are enrolled in the INFUSE-AMI study. Design: * Participants will have an MRI scan of the heart about 5 days and between 23 and 44 days after their heart attack. The MRI scan at day 5 is optional. * Participants will provide a blood sample prior to the MRI scan. * During the scan, participants will be given a contrast drug to show the blood flow to and within the heart. An electrocardiogram will be used to monitor the heart during the procedure. * No other treatment will be provided in this protocol.

Local infusion of abciximab following thrombus aspiration 2. Local infusion of abciximab and no thrombus aspiration 3. No local infusion and thrombus aspiration 4. No local infusion and no thrombus aspiration In addition, a cardiac magnetic resonance imaging (MRI) sub-study evaluating microvascular obstruction (MVO) will be performed with up to 160 subjects at up to 20 sites.
The purpose of this study is to determine if escalating doses of AMI MultiStem® delivered by catheter can safely be given to patients that have had a recent heart attack treated with stent implantation.
This study is a multicenter, randomized, double-blind, placebo-controlled clinical trial. The primary objectives of this study are to examine the safety, tolerability, and efficacy of intravenous MCC-135 in limiting final infarct size, as measured by single photon emission computed tomography (SPECT), in patients who require percutaneous coronary intervention (PCI) for a first-documented ST-segment elevation acute myocardial infarction (AMI).
Prevalence of Arrhythmias in Hemorrhagic Myocardial Infarction During the Acute Post-PCI Phase
The purpose of this study is to evaluate the efficacy and safety of LCZ696 titrated to a target dose of 200 mg twice daily, compared to ramipril titrated to a target dose of 5 mg twice daily.
This is a 6-month pilot study intended to test the effect of financial incentives on improving medication adherence in AMI patients; to test the effect on adherence of removing financial incentives; and to test the effect on the enrollment rate of modifying recruitment procedures.
The purpose of this study is to measure T-Wave Alternans (TWA) in patients with acute coronary syndrome. Researchers are blinded to clinical TWA measurements. The investigators will then try to determine if T-Wave alternans correlates with clinical outcome of patients with Acute Coronary Syndrome. During routine care of the patient, the T Wave Alternans is measured.
A novel Cardiac MRI sequence, developed by Dr. Maria Altbach (Double Inversion radial fast Spin Echo T2 mapping), has been tested clinically. It demonstrated a high sensitivity to the heart muscle swelling ("edema") in different types of heart injury, including heart attacks. The investigators propose to use T2-Map methodology in patients with acute heart attacks and to compare value of this method with other clinical and imaging parameters in predicting short-term (30 day) clinical outcomes of these patients. If successful, the project will provide an effective risk-stratification tool to identify patients with heart attack as a result of atherosclerotic disease, who require more aggressive therapeutic approach and closer follow-up after initial hospitalization.
Primary objective: To demonstrate that in hyperglycemic subjects with anterior STEMI (ST Elevation Myocardial Infarction) undergoing Percutaneous Coronary Intervention (PCI), tight glycemic control using insulin glulisine and insulin glargine, i.e. Intensive Insulin Therapy (IIT), results in reducing infarct size at day 60 versus (vs) Standard Glycemic Care (SGC). Secondary objectives: To demonstrate that tight glycemic control using insulin glulisine and insulin glargine reduces markers of inflammation and improves Left Ventricular (LV) function and Cardio-Vascular (CV) outcomes from baseline values, in hyperglycemic subjects with STEMI undergoing Percutaneous Coronary Intervention (PCI).
