Filter by:The goal of this clinical trial is to assess the effect of a vegetarian diet on innate immunity of patients with a recent acute myocardial infarction and healthy participants. Also, we will assess the willingness to adapt a more vegetarian eating habit. Study subjects will follow a vegetarian diet for five weeks, whereafter a stabilisation period of six weeks will follow. Then, participants will follow to the other dietary intervention for five weeks. Blood will be drawn at given time points to analyse inflammatory parameters.
Dysphagia is an important complication in patients with medullary infarction, the incidence rate is 57%-69%. Compared with other brain infarctions, the medulla oblongata involves multiple swallowing-related nerve nuclei, and the possibility of brain remodeling after injury is small. Dysphagia has become a prominent clinical problem in patients with medullary infarction, which can lead to malnutrition, decrease the quality of life of patients and affect the prognosis of the disease. Solving this clinical problem is particularly important for patients with medullary infarction. The incidence of UES opening disorder in patients with medullary infarction is as high as 80%, and the clinical problem of UES opening disorder is enthusiastically studied at home and abroad. At present, the intervention measures include balloon dilatation, surgical incision and botulinum toxin injection. Balloon dilatation is easy to cause mucosal edema and damage, and cricopharyngeal myotomy often has complications such as local infection, massive hemorrhage and local nerve injury. There is no significant difference between the success rate of UES botulinum toxin injection and surgical incision. Among the above measures, UES botulinum toxin injection has a good clinical application prospect, but the drug dosage and injection method are still not unified in clinic. In particular, how to accurately locate has become a hot topic in current research. On this basis, this study uses ultrasound combined with balloon localization to inject UES botulinum toxin and make clinical observation.
This Randomized controlled intervention study recruited patients diagnosed with ST-segment elevation myocardial infarction (STEMI). A total of 240 patients were enrolled in either Henagliflozin group or control group. Patients in Henggliflozin group will be given by oral administration of Henggliflozin for 6 months post acute myocardial infarction. Prior to procedure, dynamic changes in myocardial enzymes were monitored. Major cardiovascular events, including non-fatal myocardial infarction, all-cause death, revascularization due to angina, and hospitalization for acute heart failure. This study aims to assess the impact of Henggelizin intervention on the reduction of myocardial infarction size (evaluated by cardiac enzyme) and improvement of left ventricular remodeling in patients with ST-segment elevation myocardial infarction.
Pulmonary hypertension (PH) has a negative effect on acute myocardial infarction (AMI) patients and appears to be closely associated with reduced left ventricular function. However, its impact on AMI patients with reduced left ventricular function remains unclear. This retrospective study included AMI patients with reduced left ventricular function to investigate the prognostic value of PH in this specific type of patient. Meanwhile, a nomogram would be established basing on the identified independent risk factors, hoping to provide a novel risk stratification for them.
Cocaine use has increased in our country in recent decades. It is associated with cardiovascular events and early atherosclerotic disease. Acute coronary syndrome (ACS) is one of its most frequent and serious manifestations. There is a lack of scientific information on ACS associated with acute and chronic cocaine use in Argentina. This study aims to describe the socioeconomic, clinical, and coronary angiographic characteristics, as well as the extent of atherosclerotic disease in patients with ACS associated with cocaine use, and to compare them with ACS not associated with cocaine use. Methods: We propose an observational, analytical, single-center, two-phase study, with a retrospective and a prospective component. Patients with a diagnosis of ACS admitted to the coronary care unit of a high-complexity public hospital will be included. Clinical, biochemical, coronary angiographic, extracoronary atherosclerotic disease extension and prognostic variables will be described. These variables will be compared between patients with cocaine-associated ACS and non-cocaine-associated ACS.
The goal of this clinical trial is to assess the safety and efficacy of SGLT2i in limiting infarct size in patients with STEMI referred for PPCI. Eligible STEMI patients enrolled into the trial will be randomized to a SGLT2i or placebo. Cardiovascular Magnetic Resonance (CMR) imaging will be used to determine the infarct size.
Coronary heart disease and its acute complication, myocardial infarction (MI), represent the leading causes of death in Europe and the United States. Although novel treatment strategies have helped to improve survival in patients with MI, a large proportion of patients develops heart failure and is at risk of life-threatening arrhythmias. Complications arising after MI constitute a severe burden not only for the patients themselves, but also for health care systems worldwide. The likelihood of these complications depends on the area of myocardial tissue lost and the process of myocardial repair and scar tissue formation after MI ('remodeling') which are modified by the local and systemic immune response after MI. The immune response is critical after myocardial infarction. In particular, sustained overactive and prolonged inflammatory reactions lead to accentuated myocardial damage and dysfunction. Important mediators of the inflammatory reaction after MI are monocytes, T-cells, B-cells and hematopoietic stem and progenitor cells. Following MI, myeloid cells derived from the hematopoietic system drive a sharp increase in systemic leukocyte levels that correlates closely with mortality. T- and B-cells in particular act in response to specific antigens. Most of the data regarding the inflammatory response after MI, however, are derived from animal models. The immunological phenotypes after MI and their association with clinical outcome in humans are insufficiently characterized. Aims: The aim of this project is to provide establish clinically and immunologically well-characterized cohort of patients after MI This will aid in identifying novel prognostic cellular and humoral biomarkers that may be used to identify patients at a high inflammatory and immune risk and to guide clinical management. Furthermore, these mediators, in the future, may be targeted by novel antigen-specific immunomodulatory approaches. Patients with myocardial infarction (STEMI and NSTEMI) will be recruited after PCI within 24h and receive a structured follow-up. Clinical read-outs include a detailed and standardized patient history, clinical examination, standard blood work, coronary angiography, ECG, echocardiography and for subgroups, MRI. Patients will present for study visits at 6 weeks, 3 months and 12 months after the initial event. Blood will be sampled at the inclusion and during follow-up visits. Peripheral blood mononuclear cells and plasma will be stored at the Cardiovascular BioBank (CVBB) and FREEZE, both institutions at the University Hospital in Freiburg. Major adverse cardiac events (myocardial infarction, stroke, hospitalization for heart failure, cardiovascular death) will be recorded using telephone interviews and standardized queries to the local authorities. Several laboratory read-outs are planned including flow cytometry, mass cytometry, single cell RNA sequencing, T cell and B cell receptor sequencing and bulk-RNA-sequencing. In an initial approach we aim to recruit 400 patients with MI, of which we expect ≈40 to develop ischemic cardiomyopathy. Differences in immunological profiles between patients that develop MI and a propensity-matched control group will then be analyzed and correlated with clinical outcome data.
