Active clinical trials for "Infarction"

Enrollment of a population-based, prospective cohort of 3298 stroke-free adults was completed in 2001 and annual follow-up has continued since then. This collaborative study is the first prospective cohort study among whites, blacks and Caribbean Hispanics living in the same community. This grant supports continued follow-up and outcome detection and expansion of data collection in this cohort. The aims are to evaluate the relationship between vascular outcomes (stroke, myocardial infarction (MI), and vascular death) and insulin resistance, carotid intima-media thickness, carotid distensibility, and quantitative magnetic resonance imaging (MRI) measures of vascular subclinical brain disease and to determine if MRI subclinical disease accounts for race/ethnic differences in cognitive impairment. To accomplish these aims further data collection using the population-based, prospective cohort study is proposed. Stored baseline serum will be used to measure fasting insulin levels to evaluate insulin resistance. High-resolution carotid imaging data will be collected at subsequent visits to expand the measurements of subclinical carotid disease to 1300 subjects. MRIs and a neuropsychological battery emphasizing frontal executive domains will be done on 1300 subjects and quantitative analyses performed to measure white matter hyperintensities, silent infarcts, and silent cerebral microbleeds. Starting in 2005, subjects enrolled in the MRI substudy began to have echocardiograms and 24hour ambulatory blood pressure monitoring. Subjects will be followed by annual telephone interviews to ascertain stroke, MI, death, and changes in cognitive state. In-person assessment will be done for all subjects who screen positive. Community stroke surveillance will be maintained to insure stroke detection among the cohort. Specific diagnostic committees classify stroke, MI and vascular death.

Patients are screened for significant arrhythmias and other possibly significant ECG-patterns directly after discharge and two weeks after myocardial infarction using wearable devices. The home monitoring data will be linked with extensive data from electronic health records collected before, during hospital stay and after discharge. The purpose of the study is to clarify whether home monitoring of continuous ECG-signals can be used to predict and prevent serious adverse events after myocardial infarction.

Mechanical thrombectomy (MT) with a stent retriever (SR) device is now the standard intervention in ischemic stroke with large vessel occlusion. Favorable outcome is strongly associated with the successful reperfusion status. New device of MT such as contact aspiration seems promising to increase reperfusion status and clinical outcome. The main hypothesis is to show the superiority of combining the use of contact aspiration with a stent retriever compared to a stent retriever alone in treatment of acute stroke due to proximal arterial occlusion. The primary endpoint is the rate of perfect reperfusion score at the end of the endovascular procedure.

Glucagon-like peptide-1 (GLP-1), produced mainly in enteroendocrine cells, participates in energy homeostasis and glucose metabolism by regulating islet hormone secretion, gastrointestinal motility, and food intake, making GLP-1 agonist a treatment for diabetes and obesity. Pre-clinical and clinical studies have demonstrated that GLP-1 also has cardio-protection effects. GLP-1 agonists is able to improve markers of cardiac function, reduce myocardial infarct size and post-myocardial infarction remodeling in experimental myocardial infarction. And GLP-1 infusion improved left ventricular function and increases myocardial salvage in patients with acute myocardial infarction (AMI). The investigators' previous study found that GLP-1 analogues attenuated ischemia-reperfusion induced apoptosis of stem- and myocardial microvascular endothelial cells, and liraglutide (a GLP-1 analog) usage during hospital stay can prevent no-reflow and improve heart function in AMI. Therefore, the investigators carried out a cohort study to evaluate the association between plasma GLP-1 and in-hospital complications in patients with ST-segment elevation myocardial infarction.

Cardiac Rehabilitation, as art and acting science multiprofessional, is based on the training with exercises that provides the post-infarct patients to satisfactorily re-establish the patient's clinical condition and that improve the functional capacity of these individuals. Evidence shows that aerobic exercise training provides improvements in the endothelial function of this population. However, we do not yet have strong evidence of other modalities of exercise in these parameters in post-infarction patients treated with angioplasty.

Ischemic stroke occurs when an artery to the brain is blocked. If the artery remains blocked for more than a few minutes, the brain cells may die. This is why immediate medical treatment is critical. Luotai® is the brand name of Panax notoginseng finished product. 2 kinds of formulation are available, the lyophilized powder for Injection and gelatin based soft capsule. They are being used for decreasing incidence of cerebral infarction or ischemic stroke. This study will be conducted as an observational study, regarding the safety, effectiveness of Luotai treatment in acute ischemic stroke patients. This study will be carried out in approximately 360 patients with acute stroke in 6 hospitals in Vietnam - Bạch Mai Hospital, 108 Military Hospital, 103 Military Hospital, Trung Vuong Hospital, Phu Tho General Hospital, 115 Hospital. STUDY PROCEDURES: Participants will be enrolled in an unbiased manner (by consecutive sampling) and consecutive sampling method. The investigators will record participants' information required by the Case Report Form. The study which last for about 3 months, and in each of the visit, the information will be collected includes informed consent, demographic data, ischemic stroke assessment, concomitant medication, adverse reactions. A travel transportation allowance of VND 300,000 will be given for each visit. Participants will receive Luotai and other medications according to the local hospital practice in accordance with the terms of the local marketing authorization in Vietnam. The recommended dosage of Luotai is: Luotai™ injectable lyophilized powder for consecutive 14 days, Luotai soft capsules for 65 days. The participation of the study is fully voluntarily. Patients decide not to participate in the study will not be disadvantaged in any way. All collected information from participants is protected as confidential. The results of the study may be published in medical literature, but participants will not be identified. This study does not include any procedure/test that there were not indicated according to local clinical practice. There is no specific associated risks or discomforts in this study related to the participation. The results of this research may guide in further understanding the Ischemic Stroke.

The purpose of this study is to compare the risk of cardiovascular events associated with the use of sodium-glucose cotransporter 2 (SGLT2) inhibitors in comparison with the use of dipeptidyl peptidase-4 (DPP-4) inhibitors among patients with type 2 diabetes. The investigators will carry out separate population-based cohort studies using health care databases in seven Canadian provinces and the United Kingdom. The study cohort will be defined by the initiation of a SGLT2 inhibitor or a DPP-4 inhibitor after SGLT2 inhibitors entered the market. Patients will be followed up until the occurrence of a cardiovascular event. The results from the separate sites will be combined by meta-analysis to provide an overall assessment of the risk of cardiovascular events in users of SGLT2 inhibitors. The investigators hypothesize that the use of SGLT2 inhibitors will be associated with a decreased risk of cardiovascular events in comparison with the use of DPP-4 inhibitors.

The purpose of this study is to assess the impact of text message reminders on adherence to medications and exercise in patients recently discharged from the hospital after a myocardial infarction (MI).

The purpose of this study is to test the expression of microRNAs related to the syndromes after the intervention of Tongguan capsule,preliminarily to investigate the mechanism of the effects of Tongguan capsule, and provide the biological foundation of curative effect of Tongguan capsule.

This study is to build a Xinjiang people registry and surveillance system for acute myocardial infarction(AMI) information about patient's basic information, patient characteristics, diagnostic test mode, the program of treatment and hospitalization outcomes including mortality, treatment complications, the cost of hospitalization and follow-up events (death, major adverse cardiac events, stroke, heart failure) of AMI patients; And to propose scientific precaution strategies aimed to prevent effectively from the incidence of AMI; And to optimize the management and outcomes of AMI patients through implementation of guideline recommendations in clinical practice, and to perform analyses and development of effective treatment strategies and predictive models of clinical ourtcomes.
