Active clinical trials for "Infarction"

The study will use 18F-PBR06/uExplorer to study the activation of macrophages and systemic perfusion in patients with ST-segment elevation myocardial infarction (STEMI) or stable angina (SA). Participants will receive the total-body PET/CT scan on the seventh day (Day 7, D7) and D180 of enrolment.

To compare clinical outcomes of myocardial infarction with non-obstructive coronary arteries (MINOCA) according to the coronary microvascular dysfunction (CMD), evaluated by optical coherence tomography (OCT), invasive and non-invasive coronary physiologic assessment.

Heart failure (HF) is an enormous health burden affecting approximately 5.1 million people in the US and is the cause of 250,000 deaths each year. Approximately 50% of HF is caused by myocardial ischemia and requires immediate restoration of coronary blood flow to the affected myocardium. However, the success of reperfusion is partly limited by intramyocardial hemorrhage, which is the deposition of intravascular material into the myocardium. Hemorrhagic reperfusion injury has high prevalence and patients have a much greater risk of adverse left ventricular remodeling, risk of fatal arrhythmia, impaired systolic function and are hospitalized at a greater rate. Recent magnetic resonance imaging techniques have improved assessment of reperfusion injury, however, the association between MRI contrasts and reperfusion injury is highly unclear, and lacks specificity to IMH. Improved imaging of IMH and accurate knowledge about its spatial and temporal evolution may be essential for delivery of optimal medical therapy in patients and critical to identify patients most at risk for adverse ventricular remodeling. The overall goal is to investigate the magnetic properties of hemorrhage and develop MRI techniques with improved specificity to hemorrhage. New MRI techniques permit noninvasive assessment of the magnetic susceptibility of tissues and can target tissue iron. Therefore, the investigators hypothesize that MRI imaging of myocardial magnetic susceptibility can map hemorrhagic myocardium. The investigators will perform a longitudinal observational study in patients after reperfusion injury to validate these methods, compare the methods with conventional MR contrasts and develop MR methods for imaging humans.

The Stroke Recovery Initiative is a nation-wide participant recruitment registry that connects people who have had a stroke with researchers who are working to develop new approaches to improve recovery after stroke.

This is a randomized, double-blind study. Human umbilical cord mesenchymal stem cells (hUC-MSC) will be treated on cerebral infarction patients, and evaluates their neurological function of convalescent period.

This study evaluates long-term outcome of patients diagnosed as acute myocardial infarction and treated with medication, coronary artery bypass surgery and percutaneous coronary intervention in Asan medical center, Korea.

Rural Americans are more likely to be unhealthy, older, living in poverty, uninsured, and medically underserved. The CDC has made achieving health equity and improving cardiovascular health for rural Americans one of their Healthy People 2020 overarching goals. ST-Elevation Myocardial Infarction (STEMI) is a life-threatening cardiovascular emergency that frequently affects people without warning within the communities the Participants live and work. Patients with STEMI have a linear relationship between first medical contact to Percutaneous Coronary Intervention (PCI) time and mortality. Delays are particularly important in STEMI patients with cardiogenic shock, who experience an excess 3.3 deaths per 100 for every 10 minute delay to PCI (for PCI times between 60-180 minutes). Delayed PCI is also associated with a higher rate of long term morbidity, including congestive heart failure and repeat MI. Unfortunately, many rural EMS agencies fail to consistently achieve the recommended 90 minute PCI time goal. Rural agencies are less likely than urban/suburban agencies to meet time goals and this disparity exposes rural patients to excess morbidity and mortality. The American College of Cardiology/American Heart Association (ACC/AHA) endorse the need for prehospital strategies to reduce total ischemic time, particularly in rural settings.

Despite progress in pre-hospital care, ambulance logistics, pharmacotherapy and PPCI techniques, ST-segment elevation myocardial infarction (STEMI) continues to confer a substantial burden of morbidity and mortality. Within the STEMI population, there is a spectrum of higher and lower risk patients. The aim of this cohort study is to collect prospectively and systematically clinical research data from STEMI patients. This cohort study is an open-end observational study to identify master switches in myocardial ischemia.

There is no up-to-date information regarding presentation, management and clinical course of patients with acute myocardial infarction (MI) in Turkey. TURKMI registry is designed to provide insight to the characteristics, management from symptom onset to the hospital discharge and outcome of patients with acute MI in Turkey.

The investigators will enroll the patients who underwent PCI and was based on real world clinical practice to collect the data regarding demographic, clinical, procedural information and clinical outcome using case report forms.
