Filter by:The hypothesis is that an educational program aimed at emergency nurses and the implementation of measures at the organizational level reduce the time between arrival at the emergency room and the opening of the artery or balloon by 40% in patients attending for acute myocardial infarction.
The HIV/HEART Aging study (HIVH) is an ongoing, prospective, multicentre trial that was conducted to assess the incidence, the prevalence and the clinical course of cardiovascular diseases (CVD) in HIV-infected patients. The study population includes outpatients from specialized HIV-care units of the German Ruhr region, who were at least 18 years of age, were known to have a HIV-infection and exhibited a stable disease status within 4 weeks before inclusion into the trial. From March 2004 (Pilot phase) to October 2022 (15 year Follow-up) 1858 HIV+ patients were recruited in a consecutive manner. The standardised examinations included a targeted assessment of medical history and physical examination. Blood was drawn for comprehensive laboratory tests including HIV specific parameters (CD4 cell count, HIV-1 RNA levels) and cardiovascular items (lipid concentrations, BNP values and renal parameters). Furthermore, non-invasive tests were performed during the initial visit, including additional heart rate and blood pressure measurements, electrocardiogram (ECGs) and transthoracic echocardiography (TTE). Examinations were completed in accordance with previously defined standard operating procedures. CVD were defined as coronary, cerebrovascular, peripheral arterial disease, heart failure or cardiac vitium.
The purpose of this research study is to discover the functions of circulating white blood cells, called monocytes, and associated circulating substances in heart attack and ischemic stroke patients. Ischemic Strokes (clots) occur as a result of an obstruction within a blood vessel supplying blood to the brain. A type of monocyte carrying a surface marker called "P2X4" helps the immune system sense and respond to danger signals from the body such as heart muscle and brain tissue injuries. The researchers expect to learn more about how these monocyte cells react to heart and brain tissue injury, and how the cells may then produce proteins or other chemical substances which promote the healing of heart muscle after heart attack and brain tissue after an ischemic stroke.
INTRODUCTION: The pharmaco-invasive strategy is a safe alternative to primary percutaneous coronary intervention (PCI) in patients with ST elevation acute myocardial infarction, who cannot be in the cathlab in less than 120 minutes. However, previous studies of this strategy used the femoral artery as the main vascular access. Current studies show that the use of the radial artery in cases of acute myocardial infarction minimizes the risk of bleeding and mortality. Therefore, in the scenario where vascular access through the forearm vessels is recommended, the best timing to perform cardiac catheterization in the pharmaco-invasive strategy is not known. OBJECTIVE: To compare the 24-hour hemoglobin drop (acute anemia) between the fast pharmaco-invasive strategy (within 3 hours) and the standard pharmaco-invasive strategy (3 to 24 hours) in patients with acute myocardial infarction (AMI) by coronary occlusion treated in Sancta Maggiore hospitals in São Paulo and underwent to cardiac catheterization through the forearm vessels. METHOD: A prospective, randomized, multicenter study will be conducted in which 120 subjects will be randomly divided for fast and standard cardiac catheterization (1: 1). Stent implantation in the culprit vessel will be performed. The primary objective is to assess whether the fast cardiac catheterization is non-inferior to the standard strategy for a hemoglobin (Hb) drop within 24 hours. Considering in the control group an average drop of Hb 0.6 ± 1g / dl and that a drop greater than 3 g/dL of Hb is related to unfavorable clinical outcome, using a two-tailed alpha of 0.05 and a power of 90% to test the non-inferiority of the fast strategy with respect to standard strategy, each group will require 60 patients, totaling 120 individuals to include. However, if Hb fall in the fast strategy is greater than 3 g/dL and this result does not reproduce in the standard strategy, the study will allow us to show the superiority of the standard approach (between 3 and 24 hours).
Aim of this study is to describe clinical and procedural characteristics of real-world population initiated on triple antithrombotic therapy (double antiplatelet therapy+anticoagulant) or double antithrombotic therapy (single antiplatelet therapy+anticoagulant) after percutaneous coronary intervention (PCI). Investigator's driven trial, retrospective (2015-2019), multicenter Italian registry. Baseline clinical characteristics as well as procedural details will be collected retrospectively. Follow-up data (minimum 6 months and maximum 5 years follow-up) will focus on combined rates of stent thrombosis and myocardial infarction (primary endpoint).
Patients with Acute Coronary Syndrome associated with de novo atrial fibrillation are randomized to benefit from either a conventional therapy associating dual antiplatelet therapy (DAPT) and anticoagulant or DAPT and an implantable monitoring device with a follow-up by telecardiology
The overall aim of the study is to evaluate if remote video exercise-based cardiac rehabilitation (exCR), offered as an alternative to centre-based exCR, can increase participation in exCR sessions post myocardial infarction (MI).
Susceptibility weighted imaging (SWI) technology has developed in the decade which is being a kind of cerebrovascular disease diagnostic tools in the clinical application, especially for paramagnetic material (such as DNA hemoglobin and hemosiderin) has a high sensitivity. The change of the signal on SWI bases on the change of local oxygenated hemoglobin content in the blood and deaeration hemoglobin content ratio, which can be used to indirectly reflect the hypoxia group oxygen intake fraction (OEF) and cerebral metabolic rate. When the intracranial vascular occlusion, corresponding responsibility vascular blood flow area of brain tissue will occur hypoperfusion, brain tissue will improve the compensation in accordance with its own OEF, causing ischemia area inside the venous drainage of deaeration hemoglobin content ratio increases and the hypointensity on SWI ,which display the asymmetric cortical vessel sign (ACVS). Studies have suggested that ACVS is more prone to early neurological deterioration and has a poor long-term outcome. After recanalization of ischemic stroke, the presence of equal CVS(return to normal) on SWI is associated with a good clinical outcome. In addition, the relationship between ACVS grade and collateral circulation in patients with acute ischemic stroke has been studied. For patients with massive cerebral infarction, the relationship between ACVS on SWI and the clinical prognosis of cerebral edema and cerebral hemodynamics is not completely clear. In this study, the clinical data of patients with massive cerebral infarction will be analyzed to explore the relationship between ACVS, cerebral edema , cerebral hemodynamic and clinical prognosis. Sodium aescinate is widely used in cerebral edema caused by cerebral hemorrhage or cerebral infarction.The main mechanism of sodium aescinate is anti - inflammatory, anti - exudate, anti - oxygen free radical, anti - edema, increase vein tension, improve blood circulation and nerve protection. In this study, investigators will investigate whether the application of sodium aescinate had an effect on ACVS on SWI in patients with massive cerebral infarction. Plasma s100-β, procalcitonin, neutrophil count, serum fibronectin, and endothelin-1 could predict cerebral edema in patients with cerebral infarction, this study will analyze the relationship between these markers and ACVS on SWI in patients with massive cerebral infarction.
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 study intends to provide important data on whether the noval method using quantitative flow ratio could predict microvascular dysfunction.
