Diabetes is a chronic disease characterized by chronic hyperglycaemia, causing microvascular and macrovascular complications. The latter lead to various disabilities: blindness, end-stage renal failure, nerve damage, formation of leg ulcers, and atherosclerosis. In people with type 2 diabetes, the probability of these atherosclerosis associated complications is twice as high as in people without diabetes. Cardiovascular diseases are also the main cause of mortality in people with diabetes. Preventive measures are therefore crucial. In people with type 2 diabetes, in addition to good glycaemic control, the choice of antidiabetic drugs is also important. Large-scale research has shown that certain glucagon-like peptide (GLP-1) receptor agonists, in addition to improving the regulation of diabetes, also have a significant effect on reducing the macrovascular complications. It is now possible to use semaglutide, a GLP-1 receptor agonist, in the tablet form. Semaglutide lowers blood sugar only when the blood sugar value rises, due to food in the digestive tract, Thus, not increasing the risk of hypoglycaemia. In addition, semaglutide has a significant effect on weight loss and very beneficial, protective effects on the cardiovascular system. Large studies have shown that in its injectable form, it significantly reduces the incidence of cardiovascular death in patients with type 2 diabetes. Therefore, the aim of the present study is to examine how semaglutide provides protective effects on the cardiovascular system and reduces the risk of diabetes type 2 associated complications. The present study will include 100 people with type 2 diabetes and last for 12 months. The subjects will receive a semaglutide oral tablet daily in addition to their current treatment (combination of metformin and a sulphonyl urea). At the beginning of the study, after 6 months and at the end of the study (after 12 months of treatment), a detailed clinical examination will be performed and blood will be taken for laboratory parameters. In addition to basic blood tests, inflammatory and oxidative stress parameters, as well as lipid fractions parameters will also be assessed. Ultrasound examination of the changes in the carotid arteries and measures of additional properties of the arteries will also be performed. The confidentiality of the data of the participants in the research will be ensured, as the data obtained during the investigation will be encrypted before processing.
Accelerated atherosclerosis in patients with systemic lupus erythematosus (SLE) is not fully explained by Framingham risk factors. The detection in asymptomatic patients of somatic mutations in genes involved in hematopoietic malignancy- defining clonal hematopoiesis of indeterminate potential (CHIP) - predisposes to cardiovascular events (CVE) in general population. We aimed to determine whether CHIP is associated with CVE in SLE.
This study will be a placebo-controlled, double-blind, randomized, phase 3 study in participants with underlying heterozygous familial hypercholesterolemia (HeFH) and/or ASCVD to evaluate the efficacy, safety, and tolerability of obicetrapib as an adjunct to diet and maximally tolerated lipid-lowering therapy
About 20% of strokes are caused by emboli deriving from a carotid plaque. In symptomatic patients with carotid stenosis grater than 70% the Carotid Endarterectomy (CEA) reduces stroke risk by about 75% and is generally accepted as being cost effective. However also in these cases there is a part of the population that, according to the morphological plaque characteristics, could better benefit from a conservative medical treatment. Improving the Best Medical Treatment, the situation seems to be even less clear in asymptomatic patients, where probably it would need to treat at least 32 patients in order to prevent one single ictus. Different parameters have been considered in order to determine, among the asymptomatic patients the ones that more than others could benefit from a surgical revascularisation instead of a medical treatment. Between these parameters, the quality of the plaque (vulnerability) and the micro-embolic signals (MES) detection with the Transcranial Doppler (TCD) Holter seems to be the most relevant. Another interesting aspect is trying to establish whether plaques can determine a different embolic risk in relation to the different histological findings. Therefore, it seems interesting and reasonable trying to establish a correlation between these two parameters in asymptomatic patients as in the symptomatic ones in order to make more and more appropriate a surgical plaque removal according to the specific risk of each patient in a set of tailored surgery. It consists in a descriptive observational study, since it intends to describe the embolic signals detection (MES) counted in automatic way with the TCD Holter, in patients affected by carotid stenosis, before and after the surgical operation. In particular it consists in a monocentric, longitudinal, prospective cohort study since it intends to analyse a group of patients (already candidates to CEA) that experiences a specific event (MES) before and after the surgical plaque removal, in a precise span of time. Since the treatment, removing the plaque, should remove the embolic focus too, a significant reduction of microembolic signals in post-operative time is expected. This reduction has been esteemed around about the 70% among candidates to CEA. Patients taken on responsibility of the equipe will undergo an ultrasonographic investigation for the carotid stenosis, histological characterization of the plaque based on the Gray-Weale classification and TCD-Holter for MES.

To evaluate the long-term clinical outcomes and prognostic factors in patients with coronary artery disease (CAD) undergoing invasive coronary angiography (ICA), intravascular imaging, or invasive physiologic assessment.
During July 2019 to August 2020, a single-blind clinical trial was done to 36 patients with Graves' disease. At the beginning of the study, subjects were accommodated into 2 groups, 17 into PTU groups and 19 into methimazole groups. There were 24 subjects who finished the study, 13 from PTU group and 11 from methimazole group. Blood serum was collected for HOMA-IR, LDL-R, NFĸB, sICAM-1, sVCAM-1 and sE-selectin examination. Meanwhile stiffness and thickness of carotid artery was measured using PWV and cIMT.
Cardiological complications of oncological treatment, including the most serious of them cardiotoxicity and heart failure, constitute a significant and still unsolved clinical problem. A history of hypercholesterolaemia and coronary artery disease in cancer patients, is one of the risk factors for cardiotoxicity. In recent years, a protective effect of statin treatment on the development of heart failure in cancer patients has been observed. ANTEC (Atherosclerosis iN chemoTherapy-rElated Cardiotoxicity) is a prospective observational study aimed at assessing the impact of the advancement of atherosclerotic lesions in the coronary arteries assessed in computed tomography on the development of left ventricular systolic dysfunction in cancer patients at high risk of myocardial damage. A group of 80 patients diagnosed with cancer before starting high-dose anthracycline chemotherapy (doxorubicin ≥ 240 mg / m2 or epirubicin ≥ 600 mg / m2 body weight), without a history of heart failure and coronary artery disease, will be included in the study. The total follow-up of patients was planned for 12 months. The primary endpoint is time to onset of left ventricular systolic dysfunction as assessed by echocardiography. The secondary composite endpoints include all-cause death, cardiovascular death, myocardial infarction, and stroke. Additionally, the assessment will include: the severity of atherosclerotic changes in the coronary arteries and the calcification index in computed tomography, the percentage decrease in left ventricular ejection fraction, GLS (global longitudinal strain) in echocardiography, and changes in the concentration of biomarkers involved in inflammatory and atherosclerotic processes. This is the first study of this type, which we hope will contribute to a better understanding of the pathophysiology of cardiotoxicity development and to changing the standards of management of oncological patients and improving survival in this group of patients.
