620 Clinical Trials for Various Conditions
The primary objective of this study is to evaluate the effectiveness of early treatment with evolocumab plus routine lipid management vs routine lipid management alone when administered in the acute setting to reduce myocardial infarction, ischemic stroke, arterial revascularization, and all-cause death in subjects hospitalized for an acute myocardial infarction (non-ST-segment elevation myocardial infarction \[NSTEMI\] and ST-segment elevation myocardial infarction \[STEMI\]).
This study will assess the effect of lowering low-density lipoprotein cholesterol (LDL-C) with evolocumab on major cardiovascular events in adults without a prior myocardial infarction (MI) or stroke who are at high risk of a cardiovascular event.
This study is being carried out to see if a new drug called ticagrelor given twice daily in addition to the ASA therapy decreases the frequency of cardiovascular events (e.g., death from heart disease, heart attack, or stroke).
AliveCor (www.alivecor.com) has developed several electrocardiogram (ECG) devices that interface with iOS and Android smartphones and tablets via various Kardia apps. The current Kardia family of devices can measure single lead and six limb-lead ECGs, depending on the device. KardiaMobile, KardiaMobile 6L, and KardiaMobile Card have FDA clearance for ECG rhythm recording. A modified single-lead Kardia smartphone 12-lead ECG was previously validated in the multicenter ST LEUIS study for the diagnosis of ST-Segment Elevation Myocardial Infarction (STEMI) and Non-ST-Elevation Myocardial Infarction (NSTEMI). Recently, AliveCor developed a new device: AliveCor (AC) 12-lead (12L) ECG System to record simultaneously 4 leads of ECG and then generate complete 12-lead ECGs. A previous protocol at the University of Oklahoma involved 200 subjects with early prototypes of the AC 12L device with the specific aim to validate that it accurately generated 12-lead ECGs as compared to simultaneously acquired FDA-cleared 12-lead ECGs. The prototype version of the AliveCor 12L ECG System simultaneously measured four channels of ECG (leads I, II, V2, V4), calculated the remaining limb leads as is standard for 12-lead ECGs (Leads III, aVR, aVL, aVF) and synthesized the remaining 4 precordial ECG leads (V1, V3, V5, V6). This protocol will serve to validate the production version of the system against standard 12-Lead ECGs for the diagnosis of STEMI and NSTEMI in patients admitted to the Emergency Department or directly to the Cardiac Cath Lab for the evaluation of chest pain. It is anticipated that the waveforms for each of the 12 leads from the AC 12L ECG System will be highly correlated with the corresponding leads from the comparator commercially available 12-lead ECG devices used at participating sites. The purpose of this study is to clinically validate that the four-channel AC 12L ECG device can enable the diagnosis of STEMI and NSTEMI in a non-inferior manner to existing 12-lead ECG devices.
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 goal of this pilot study is to use total body PET/CT imaging to examine the relationships between stress, amygdala activation, and arterial wall inflammation in participants before and after participating in a multi-modal stress reduction program.
This is an observational study based on secondary data extracted from multiple register-based data sources in the US and Europe (Sweden, United Kingdom, Italy, Germany). The study will include patients initiating treatment with ticagrelor 60 mg after a myocardial infarction in real-world clinical practice, and describe their patient characteristics and duration of treatment. If the a priori threshold of 5,000 person-years on treatment with ticagrelor 60 mg is met, outcome events (bleeding and cardiovascular events) will also be analysed and described.
Patients whose kidneys are no longer able to work as they should and require treatment to filter wastes from the blood (hemodialysis) are at high risk for blood clots that form in blood vessels (thrombosis) blocking blood flow that causes heart attacks, strokes, and other life-threatening conditions. BAY2976217 is under clinical development for prevention of thrombosis. The goal of the study is to learn more about the safety of BAY2976217, how it is tolerated and the way the body absorbs, distributes and gets rid of the study dug given as multiple doses in participants with renal impairment who require hemodialysis.
The goal of the study was to evaluate the effect of single administration of RPH-104 at 80 mg and 160 mg on parameters of systemic inflammation and outcomes of the disease in subjects with ST-segment elevation myocardial infarction (STEMI)
This is an international, multicenter, parallel-group, randomized, double-blind, placebo-controlled trial in patients who have been stabilized during hospitalization for acute heart failure, evaluating the effect of in-hospital initiation of dapagliflozin versus placebo on the clinical outcome of cardiovascular death or worsening heart failure.
Unplanned readmissions after hospitalization for acute myocardial infarction (AMI) are among the leading causes of preventable morbidity, mortality, and healthcare costs. Digital health interventions (DHI) could be an effective tool in promoting self-management, adherence to guideline directed therapy, and cardiovascular risk reduction. A DHI developed at Johns Hopkins-the Corrie Health Digital Platform-includes the first cardiology Apple CareKit smartphone application, paired with an Apple Watch and iHealth Bluetooth-enabled blood pressure monitor. Corrie targets: (1) self-management of cardiac medications, (2) self-tracking of vital signs, (3) education about cardiovascular disease through articles and animated videos, and (4) care coordination that includes cardiac rehabilitation and outpatient follow-up appointments. In this prospective study, STEMI or type 1 NSTEMI patients are being enrolled to use the Corrie Health Digital Platform beginning early during participants' hospital stay. Enrollment sites include Johns Hopkins Hospital, Johns Hopkins Bayview Medical Center, Massachusetts General Hospital, and Reading Hospital. The primary objective is to compare time to first readmission within 30 days post-discharge among patients with the Corrie Health Digital Platform to patients in the historical standard of care comparison group.
The investigators aim to evaluate Wellframe, a patient engagement platform that includes a mobile phone application for patients, for its impact on supporting patients who have undergone a percutaneous coronary intervention. The patient mobile app has articles about cardiovascular disease and other health related topics, patient-reported outcomes surveys, physical activity tracking, reminders for medications and upcoming appointments, and two-way communication with a Wellframe Health Advocate. The Wellframe Health Advocate encourages patients to achieve their health goals and stay engaged in their health. The feasibility of onboarding patients to the app and the clinical efficacy of the platform will be evaluated.
Is the Smartphone ECG (electrocardiogram) an acceptable replacement for a standard ECG in the identification of STEMI (ST Elevation Myocardial Infarction).
This study evaluates whether achieving 25-hydroxyvitamin D (25\[OH\] Vit D) levels (\>40 ng/mL) among myocardial infarction patients will result in a reduction of cardiovascular-related adverse events. Half of the patients will be randomized to receive standard of care and half will receive clinical management of 25\[OH\] Vit D levels.
Type 2 myocardial infarction (MI) is defined as myocardial necrosis that results from an imbalance of myocardial oxygen supply and demand. Although type 2 MI is highly prevalent in patients with critical illness and strongly associated with mortality, the pathophysiology remains poorly understood. Inflammation is central to the development of atherosclerosis, plaque rupture, and other subtypes of MI, but the role of inflammation in type 2 MI and myocardial necrosis has not been defined. The investigators aim to to delineate the mechanistic role of inflammation in myocardial necrosis and type 2 MI complicating critical medical illness.
The intent of this clinical study is to answer the questions: 1) Is the proposed treatment safe? and 2) Is treatment effective in improving cardiac function and clinical outcomes?
The purpose of this study is to assess the effectiveness and safety of rivaroxaban compared with placebo (inactive medication), in reducing the risk of death, myocardial infarction or stroke in participants with heart failure and significant coronary artery disease following an episode of decompensated heart failure.
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.
This study will test whether darapladib can safely lower the chances of having a cardiovascular event (such as a heart attack or urgent coronary revascularization (e.g. medical procedures performed to restore the normal blood flow in patients with atherosclerosis)) when treatment is started within 30 days after an acute coronary syndrome (also called ACS).
The purpose of this study is to determine whether KAI-9803 is safe and effective in reducing infarct size in subjects with ST elevation myocardial infarction (heart attack) undergoing a percutaneous coronary intervention (PCI). A select number of sites will also participate in a substudy where eligible patients will undergo an additional procedure;cardiac magnetic resonance imaging.
The purpose of this study is to review cause of death in patients undergoing prostate brachytherapy at a single institution. Furthermore, we are analyzing patients undergoing androgen deprivation therapy and whether or not this contributed to cardiovascular deaths, specifically myocardial infarction.
The purpose of this study is to determine if veliflapon (DG-031)can prevent a heart attack or stroke in African American patients with a history of unstable angina or myocardial infarction.
The purpose of the study is to determine whether adult stem cells \[Provacel™(PUMP1)\] are safe and possibly effective in the treatment of acute myocardial infarction (heart attack).
The purpose of this study is to assess the effect of heart muscle viability on left ventricular (LV) remodeling after a heart attack; to explore the relationships between retained viability of the area of tissue death (infarct zone), LV remodeling, response to the Occluded Artery Trial (OAT) intervention, and response to late percutaneous coronary intervention of the infarct related artery (IRA).
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.
The goal of this observational study to measure the heart's microvascular function in the setting of a myocardial infarction (MI), or heart attack, using a method called continuous saline thermodilution (CST). The participants will include people who are experiencing MI from sudden and complete blockage of a coronary artery requiring immediate balloon and/or stent therapy. After getting the balloon and/or stent therapy, participants will have their heart's microvascular system tested using CST. The main questions it aims to answer are: * What measurements using CST can we expect from the heart's microvascular system during a treated MI? * Can CST measurements during a treated MI predict the amount of heart muscle that is injured and that recovers? For this study, participants will undergo measurement of their heart's microvascular function after balloon and/or stent therapy for the MI. They will then receive an MRI scan of the heart several days after the MI.
Prevalence of Arrhythmias in Hemorrhagic Myocardial Infarction During the Acute Post-PCI Phase
Hemorrhagic Myocardial infarctions are at high risk for mechanical complications including cardiac rupture. Prediction of vulnerable myocardial segments is an important step for the stratification of hemorrhagic MI patients. Wall motion index ratio is an important parameter to determine regions of high vulnerability within the 17-segment LV model of hemorrhagic MI.
Registry analysis for prevalence of hemorrhagic myocardial infarction in the United States
This study is open to adults aged 18 and over who have just had a heart attack. The purpose of this study is to find out whether a medicine called BI 765845 helps people who have had a heart attack. The investigators also want to test how well different doses of BI 765845 work and how they are tolerated by people who have had a heart attack. Participants are randomly assigned to receive either BI 765845 or placebo. Placebo treatments look like BI 765845 treatments but do not contain any medicine. Participants are about 3 times as likely to receive BI 765845 than placebo. Participants are in the study for 3 months. During this time, they visit the study site 7 times and get 3 phone calls from the site staff. At the visits, the doctors use clinical tests to check the health of the heart. The results are compared between the BI 765845 and placebo groups to see whether the treatment works. The doctors also regularly check participants' health and take note of any unwanted effects.
