Filter by:In this proposal, the investigators will demonstrate the feasibility and noninferiority of telerobotic ultrasonography as compared to traditional manual acquisition in performing a limited carotid Duplex examination and in carotid plaque detection.
The aim of GEOMETRY study is to investigate the correlation between coronary plaque geometric modifications and lesion vulnerability in patients with suspected coronary artery disease referred for cardiac computed tomography angiography (CCTA). Furthermore the study will evaluate the impact of plaque eccentricity and morphology on the rate of major adverse cardiovascular events (MACE) for a 2 years follow-up period.
• The aim of the VIP study is to investigate the impact of vulnerability markers (inflammatory serum biomarkers for systemic vulnerability, coronary shear stress and vulnerability mapping for pancoronary vulnerability, and imaging-based plaque features for systemic vulnerability) on the rate of major adverse cardiovascular events caused by progression of the non-culprit lesion in patients with acute ST or non-ST segment elevation myocardial infarction who undergo revascularization of the culprit lesion during the acute event. Furthermore, the study will evaluate the rate of progression of non-culprit lesions towards a higher degree of vulnerability, based on coronary computed tomography angiographic assessment at 1 year after enrollment.
Recent studies have shown that the systemic inflammation caused by periodontal disease (PD) can determine important changes in the coronary arteries, favoring atherosclerosis progression and development of acute coronary syndromes (ACS). The aim of ATHERODENT study is to assess the interrelation between PD, inflammation and progression of coronary atherosclerosis in patients with ACS. Material and methods: This case-control observational study will enroll 100 patients (group 1 - ACS and associated PD, and group 2 -ACS and no PD), in whom the following data will be collected: (1) demographic and clinical data, (2) cardiovascular risk factors, (3) full characterization of PD markers, (4) systemic inflammatory biomarkers, (5) imaging biomarkers derived from transthoracic echocardiography, computed tomography, coronary angiography, optical coherence tomography and intravascular ultrasound, and (6) assessment of the presence of specific oral bacteria in samples of coronary plaques collected by coronary atherectomy, which will be performed during percutaneous revascularization interventions, when indicated in selected cases, in the atherectomy sub-study. The follow-up will be performed at 1, 3, 6, 12, 15, 18 and 24 months. The primary endpoint of the study will be represented by the rate of major adverse cardiovascular events (MACE rates) in PD vs non-PD patients and in correlation with: (1) the level of systemic inflammation triggered by PD and/or by ACS at baseline; (2) the vulnerability degree of atheromatous plaques in the coronary tree (culprit and non-culprit lesions); and (3) the presence and burden of oral bacteria in atheromatous plaques. Secondary endpoints will be represented by: (1) the rate of progression of vulnerability degree of non-culprit coronary plaques; (2) the rate of progression of atheromatous burden and calcium scoring of the coronary tree; and (3) the rate of occurrence of left ventricular remodeling and postinfarction heart failure.
The aim of Multiplaque clinical study is to assess the vulnerability degree of the atheromatous plaques, before and after a myocardial infarction (MI), based on multiomics analysis, associated with invasive and non-invasive data. In this study, a multi-parametric model for risk prediction will be developed, for evaluation of the risk that is associated with the vulnerable coronary plaques in patients that have suffered an acute coronary syndrome. In the study, evaluation of the imaging characteristics of these coronary plaques will be performed with the use of CT, OCT, IVUS and invasive angiography. We will study the correlation between plaque evolution and (1) the degree of vulnerability at baseline, (2) multiomics profile of the patients and (3) clinical evolution during follow-up. Also, new techniques for evaluation of the functional significance of coronary stenoses will be studied and validated, such as calculation of the fractional flow reserve or determination of shear stress in areas that are localized within the near vicinity of the vulnerable coronary plaques.
The present study aims at assessing the ability of 68Ga-NODAGA-RGD PET/CT for the detection of inflammatory atheromatous plaques in the carotid arteries, compared to 18F-FDG PET/CT, MRI and US and to determine the contribution of each imaging technique. Current gold standard for inflammation is histopathology. Hypothesis : 68Ga-NODAGA-RGD might give a better initial evaluation of patients with atheromatous plaques in the carotid artery eligible for endarterectomy.
