Filter by:Non-commercial, multicentre, randomised, double-blind, parallel group, placebo-controlled clinical trial. Eligible patients were randomly assigned (1:1) using a secure, central, interactive, web-based response system, to intervention FCM or placebo arm. Time of observation 12 months [12 main study + 3 years follow up in substudy B]. Primary Study Objective: Primary: Evaluation of the effect of i.v. FCM treatment compared with placebo on the risk of cardiovascular (CV) death, the risk of heart failure events (HFE*) (number of events and time to first event) during the 12-month follow-up and the change in quality of life (QoL) assessed using EQ-5D during the 8-month follow-up in patients with recent AMI and ID (with an implementation of a win ratio approach in a hierarchical descending order). *HFE: unplanned hospitalization for HF (including unplanned visit at emergency department due to HF), ambulatory significant intensification of diuretic therapy (either starting i.v. loop diuretic or more than doubling oral loop diuretic dose or de novo initiation of oral loop diuretic therapy due to HF signs/symptoms).
In this study the investigators aim to examine the role that fibrosis plays in heart conditions such as aortic stenosis , chemotherapy-induced cardiotoxicity and carcinoid syndrome . Fibrosis is a common final result following any injury to the heart muscle and the investigators aim to identify this process early and in its active state. This will be examined by using a radiotracer 68Ga-FAPI or 18F-AlF-FAPI and PET-MRI or PET-CT.
This is an European prospective cohort study from February 2023 until February 2024. The investigators want to analyze the clinical success, efficacy and safety of consecutive patients who presented with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) for de novo heavily calcified culprit lesion using plaque modification devices before stent implantation.
The goal of this prospective study is to evaluate the role of cardiovascular magnetic resonance (CMR) in patients with suspected non-ST elevation myocardial infarction (NSTEMI). The main endpoint is the reclassification rate, defined as the number of patients in whom the information provided by pre-angiography CMR affects the revascularization strategy or the final diagnosis. Participants will undergo to CMR before invasive coronary angiography (ICA).
Among patients early following ST-segment (ST) elevation myocardial infarction, transcutaneous vagus nerve stimulation is associated with a reduce of the burden of premature ventricular contractions in the first 40 days post-myocardial infarction (MI). The above hypothesis will be tested with a randomized, prospective, parallel, single-blind clinical trial. The expected study duration is approximately 12 months from the time the first subject is enrolled (planned for June 2023) to the time of study's termination date (December 2024). Patient enrollment is planned to take place at two major centers in Greece. The researchers will obtain approval by the institutional review board (IRB).
Cardiac troponin is central to the diagnosis of myocardial infarction and high-sensitivity cardiac troponin (hs-cTn) assays are the preferred choice for the assessment of patients with suspected acute coronary syndrome. Since the introduction of hs-cTn assays in Europe in 2010, most hospitals have switched from contemporary sensitive cardiac troponin assays to a hs-cTn assay. The implementation of hs-cTn assays has led to an increase in the number of patients identified with myocardial injury. Although both hs-cTnI and hs-cTnT assays are recommended in current guidelines, the impact of switching from a hs-cTnI assay to a hs-cTnT assay on clinical practice is unknown. At this point, no studies have evaluated the impact of implementing sex-specific hs-cTnT thresholds on the diagnosis of myocardial infarction and outcome in clinical practice. The investigators propose to determine the proportion of patients with and without myocardial injury admitted to the hospital before and after implementation of a hs-cTnT assay and to evaluate the impact on investigations, care and clinical outcomes in consecutive patients with suspected acute coronary syndrome.
Study of role of colchicine in reducing periprocedural myocardial injury in patients prepared for elective PCI and its role in reduction of MACEs.
Despite the use of guideline directed optimal medical therapy, 12% of patients with stable coronary heart disease and 18% of patients with recent acute coronary syndrome experience recurrent major adverse cardiovascular events 1. The risk of recurrent cardiovascular events may be related to persistent elevation of thrombin beyond the index event 2,3 which leads to progression of cardiovascular disease by inducing inflammation, endothelial dysfunction and thrombosis 4. In patients with coronary heart disease, vitamin K antagonists (VKAs) and direct oral anticoagulants (DOACs) have been explored as secondary prevention strategies and have shown cardiovascular benefits at the cost of higher bleeding events 5,6,7,8. howeverLeft ventricular thrombus (LVT) usually appearswithin 1 month after ST-segment elevation myocardial infarction (STEMI) and mostlyforms after anterior STEMI.9,11Although the prevalenceof LVT after acute myocardial infarction hasdecreased dramatically in modern times due to the progress of reperfusion therapy, LVT incidence in patients with anterior STEMI remains at 4% to 26%.10,12 It complicates acute myocardial infarction and is associated with a higher incidence of poor outcomes.9
TITACIPPI (Tirofiban with Intravenous Thrombolysis in Acute Anterior Choroidal Infarction [ACI] and Paramedian Pontine Infarction [IPP]) study aimed to evaluate the efficacy and safety of simultaneous infusion of tirofiban with intravenous thrombolysis (IVT + tirofiban group) compared to IVT alone (IVT alone group) in patients with ACI or PPI. TITACIPPI study is a retrospective, single-center observational study conducted from March 01, 2014, to December 31, 2022.
A single center, prospective, observational study to compare fractional flow reserve (FFR) and intravascular ultrasound (IVUS) percutaneous coronary intervention (PCI) optimization strategies on the functional PCI result (assessed with FFR) immediately post PCI and at 9-12 months after the treatment of long coronary artery lesions.
