Filter by:The rupture or erosion of an atherosclerotic plaque with thrombosis or embolization often underlie heart attacks and strokes. The early identification of patients with atherosclerotic plaques prone to rupture or erosions, vulnerable plaques (VP), and their treatment before the occurrence of events is, therefore, one of the greatest cardiovascular challenges today. Possible approaches for early detection of VP include imaging techniques allowing visualization of plaque structure, circulating biomarkers and better understanding of the pathophysiologic mechanisms of the disease. In the carotid plaque imaging project the investigators study human atherosclerotic plaques (that are removed by endarterectomy) to disclose their underlying structure and mechanisms, finding possible novel therapeutic targets or markers for VP. The investigators also study plaque structure with imaging methods and try to develop new ways to detect VP using circulating or imaging markers.
The goal of this randomized controlled trial is to assess the impact of disclosing a high polygenic risk result for coronary artery disease on change in cardiovascular health over one year.
A significant challenge in medical care is atherosclerotic occlusion of peripheral arteries, such as lower extremities and brachiocephalic arteries, which can eventually lead to loss of limbs or fatal ischemic strokes. Revascularizing surgical interventions can restore the lumen of the arteries and provide an effective way to treat such patients. However, up to a third of patients need re-intervention or experience cardiovascular complications within a year after surgery. The purpose of this study is to evaluate the effect of adding the natural dietary supplement Allicor to conventional treatment on the incidence of cardiovascular complications and treatment effectiveness 12 months after revascularization. Another valuable area of investigation is the search for predictors of long-term cardiovascular complications after revascularization, which could be markers of inflammation and heteroplasmy levels in the patient's mitochondrial genome.
Cerebral hyperperfusion syndrome (CHS) was initially described as a clinical syndrome following carotid endarterectomy (CEA), but it may present in both CEA and carotid artery stenting, and is characterised by throbbing ipsilateral frontotemporal or periorbital headache, and sometimes diffuse headache, eye and face pain, vomiting, confusion, macular oedema, and visual disturbances, focal motor seizures with frequent secondary generalisation, focal neurological deficits, and intracerebral or subarachnoid haemorrhage. Knowledge of CHS among physicians is limited. Most studies report incidences of CHS of 1-3% after carotid endarterectomy. CHS is most common in patients with increases of more than 100% in perfusion compared with baseline after carotid revascularization procedures and is rare in patients with increases in perfusion less than 100% compared with baseline. The pathophysiological mechanism of CHS remains only partially understood. The chronic lowflow state induced by severe carotid disease results in a compensatory dilation of cerebral vessels distal to the stenosis, as part of the normal autoregulatory response, to maintain adequate cerebral blood flow (CBF). In this chronically dilated state, the vessels lose their ability to autoregulate vascular resistance in response to changes in blood pressure. In fact, it has been shown that this dysautoregulation is proportional to the duration and severity of chronic hypoperfusion. After revascularization and reperfusion, the impaired cerebral autoregulation could then contribute to a cascade of intracranial microcirculatory changes, as explained above, with an inability of reaction toward the augmentation of the CBF after the carotid recanalization. Although most patients have mild symptoms and signs, progression to severe and life-threatening symptoms can occur if CHS is not recognised and treated adequately. Because CHS is a diagnosis based on several non-specific signs and symptoms, patients may be misdiagnosed as having one of the better-known causes of perioperative complications like thromboembolism.
Primary Study Objective : To compare the effects of low-dose rivaroxaban plus aspirin versus aspirin on atherosclerotic plaque inflammation using serial FDG Positron Emission Tomography/Computed Tomography(PET-CT) imaging of carotid artery and ascending aorta. Secondary Study Objective : To compare the effects of low-dose rivaroxaban plus aspirin versus aspirin on biomarkers including high-sensitivity C-Reactive Protein(CRP) and lipid profiles.
The purpose of the SMART-EXAM (SMart Angioplasty Research Team-Pragmatic Randomized Trial for Comparing Routine versus As-Needed EXercise or Pharmacologic Stress Testing in Asymptomatic Patients with High-Risk Coronary CalciuM) trial is to compare the major adverse cardiovascular events between routine stress testing and as-needed stress testing in asymptomatic patients with high-risk coronary calcium (Agatston Score ≥ 400) without proven ASCVD.
The aim of the study is to evaluate the association between apical periodontitis (AP) and atherosclerotic cardiovascular disease (ASCVD) by assessing the multiplicative effect of AP on secondary outcomes of ASCVD. Sixty-two subjects will be enrolled from the Unit of Endodontics and Restorative dentistry and allocated into 2 distinct groups depending on the presence or absence of periapical lesions. Group 1 will be composed of 31 patients with radiographic signs of AP. On the contrary, another 31 healthy individual (free from clinical and radiographic evidence of AP) meeting the inclusion and exclusion criteria were included as controls (group 2) A complete dental examination will performed on each patient in both groups. All the patients will be subjected to a cardiovascular examination to assess carotid intima-media thickness (cIMT), presence of abdominal aortic aneurysm, presence of peripheral pulses through echo-color-doppler.
The study will show the influence of inflammatory bowel disease on the risk of development of atherosclerosis
Interventional study to compare standard of care vs standard of care plus the use of a medication therapy management smartphone app (mediteo m+, Mediteo GmbH, Heidelberg) in patients with atherosclerotic cardiovascular disease and indication to start high intensity statin therapy.
To determine whether treating to an LDL-C target of 25 to <70 mg/dL is superior to an LDL-C target of 70 to <100 mg/dL with respect to major cardiovascular events (cardiovascular death, myocardial infarction, stroke, hospitalization for unstable angina, or coronary revascularization) in patients aged ≥75 years with atherosclerotic cardiovascular disease (ASCVD). To determine whether treating to an LDL-C target of 25 to <70 mg/dL is non-inferior to an LDL-C target of 70 to <100 mg/dL with respect to major safety events (hemorrhagic stroke, new-onset diabetes, muscle-related events, neurocognitive adverse events, new or recurrent cancer, cataract, or hepatic disorder [Alanine aminotransferase (ALT)/Aspartate aminotransferase (AST) >3× ULN, or total bilirubin >2× ULN]) in patients aged ≥75 years with ASCVD.
