Filter by:Cardiovascular disease is a complication of type 1 diabetes (T1D), a life-long disease, usually diagnosed in childhood. The goal of this project is to determine the timing and factors leading to vascular damage in children from T1D diagnosis.
The purpose of this research study is to understand what effect near complete estrogen deprivation (NCED) therapy has on the heart in breast cancer patients. Investigators want to understand if NCED changes how the heart works.
Experimental data suggest that glutamine catabolism in involved in the activation of macrophages by generating TCA(Tricarboxylic acid) intermediates that promote the pro-inflammatory polarization of macrophages. The project investigates the possible link between glutaminolysis, monocytes polarization and diabetes related cardiovascular complications in humans
Cardiovascular diseases are the first mortality cause in Occidental countries. Surgery and anesthesia can provoke hemodynamic instability and stimulation of the sympathetic nervous system as well as bleeding or thrombosis. These factors as top of some post-operative factors such as tissular hypoxemia, can result in cardiovascular complications. Developing a tool to predict post-operative cardiovascular complication could influence peri-operative measures by stratifying the population at risk. UCLouvain has developed a patented technique using a paramagnetic electronic resonance spectrometry (EPR) able to quantify a paramagnetic component, nitrosylated hemoglobin (HbNO) of the erythrocytes drawn from venous blood. This HbNO has been correlated to the traditional cardiac risk factors. In this study, we will assess the HbNO of patients prior to surgery and will correlate it with cardiovascualr and non cardiovascular complications in order to evaluate the predictive aspect of our biomarker.
The primary hypothesis of the BETTER pilot trial is that B-type natriuretic peptide (BNP) directed medical therapy prior to noncardiac surgery will be associated with improved cardiovascular outcomes, when compared to standard of care.
Differences in efficacy and safety between new oral anticoagulants (NOAC) and vitamin K antagonist (VKA) in real practice remain uncertain. The few existing ambulatory studies did not answer all NOAC specific issues, such as prescription habits and motives, patients characteristics, biological monitoring, as well as the occurrence of major and minor thromboembolic events, especially in France where warfarin is less frequently prescribed. Therefore, in order to describe clinical and follow up characteristics of patients receiving oral anticoagulants, the investigators will set up a national prospective cohort to compare the occurrence of thromboembolic events between VKA and NOAC in primary care.
The National Register of Nephrology in 2007 shows, similarly to the European data, a problem of a high mortality rate among Polish dialysis patients. The main reason of death among chronically dialysis patients are cardio - vascular system diseases. According to "The Report on the Condition of Renal Replacement Therapy in Poland in 2007", these diseases are the cause of 53% deaths in Poland. The patients with chronic kidney disease (PChN) are particularly at risk of cardio - vascular complications. These complications occur on average 30 times more often than in the whole population, and among young dialysis people, these complications occur 300 times more often. In the development of cardio - vascular complications polyunsaturated Omega-3 acids (especially eicosapentaenoic acid - EPA and docosahexaenoic acid - DHA) take a special position. The reaction of polyunsaturated Omega-3 acids on the cardiovascular system results from the enrichment of phospholipids of cell membranes within EPA and DHA. It should be noted that their impact is dependent on the type of acid and on the dose. Docosahexaenoic acid reacts with lipids and lipoproteins, blood pressure, heart rate, amount of glucose, and eicosapentaenoic acid is responsible for antiplatelet effect. This project is aiming at defining and elaborating on the connection between Omega-3 acids, and cardiovascular complications, their influence on the functioning of the cardiovascular system, and moreover, a better understanding of the effects of therapeutic and pharmacological therapies in patients at different stages of chronic kidney disease. Carrying out this project will be a good start to shape an international project in this area.
Introduction: Patients undergoing noncardiac surgery are at increased risk of cardiovascular complications. The development of methods that can accurately predict the occurrence of these events is of critical importance and large studies have been published with this purpose. Based on these studies, several algorithms have been proposed to predict of cardiovascular events postoperatively. However, quantification of this risk is often difficult to measure, especially in those patients with subclinical disease, not always detected in routine evaluation. The ankle brachial index (ABI) has proved a valuable tool in the quantification of cardiovascular risk, and perhaps the most promising when compared with other methods. It is easy, cheap, fast and feasible in office care, with a great acceptance between patients and small intra and inter observer variability. Despite strong evidence of the utility of ABI as a tool in assessing cardiovascular risk, there are no data about the use of ABI in other patients referred for non vascular surgery, which constitutes the majority of operations performed worldwide. Objectives: To evaluate the use of ABI as a predictor of cardiovascular events in patients undergoing non-cardiac and non-vascular surgery and its applicability as a tool in the reclassification of patient risk groups established by guidelines for perioperative evaluation. Methods: 300 moderate to high risk patients referred for non-vascular and non-cardiac will be included. Data about risk factors, signs and symptoms, physical examination and treatment used will be collected before surgery. The ABI will be measured and the patient will be monitored for 30 days to the detection of cardiovascular events: death from any cardiovascular causes, unstable angina, nonfatal myocardial infarction, isolated elevation of troponin, decompensated heart failure, cardiogenic shock, stop nonfatal heart failure, pulmonary edema, stroke and lower limb ischemia. Postoperative electrocardiogram, total creatine kinase, MB fraction and troponin I will be measured daily until 3º day and whenever clinically indicated.
RATIONALE: Studying samples of blood and urine in the laboratory from patients with cancer receiving bevacizumab may help doctors learn more about changes that occur in DNA and identify biomarkers related to high blood pressure. PURPOSE: This phase I trial is studying potential biomarkers for bevacizumab-induced high blood pressure in patients with malignant solid tumors, including breast cancer, colorectal cancer, non-small cell lung cancer, head and neck cancer, ovarian cancer, fallopian tube cancer, or primary peritoneal carcinoma.
This randomized pilot clinical trial studies rosuvastatin in treating women with cardiovascular complications who are undergoing chemotherapy for breast cancer. Rosuvastatin may prevent or lessen cardiovascular complications in patients undergoing chemotherapy for breast cancer
