NCT01566305
Rationale and objective: Based on the results of a pilot study, the objective of the present study is to evaluate whether buttermilk lower serum LDL cholesterol concentrations and can prevent the serum LDL cholesterol raising effects of eggs. Study Design: The study has a randomized placebo-controlled factorial 2x2 design. The total study duration is 14 weeks, consisting of a 2 weeks run-in period and a 12 weeks experimental period. Subjects will be stratified for age, gender and BMI over the experimental groups. Study population: One hundred and eight healthy male and female subjects, aged 18-70 years, with slightly elevated serum total cholesterol concentrations (5.5-8.0 mmol/l). Intervention: During the entire study period, volunteers are instructed to consume a diet according to the Dutch dietary guidelines (35 en% fat (10 en% saturated fat), 50-55 en% carbohydrates). During the two weeks run-in period all subjects will drink daily at lunch 100 mL skimmed milk. During the 12 weeks experimental period, a first group of subjects will continue drinking the skimmed milk (control group), while a second group will consume a low-fat buttermilk, a third group skimmed milk enriched with egg-yolk, and a fourth group egg-yolk incorporated into a low-fat buttermilk based beverage. The egg-yolk will be enriched in lutein. Whole egg consumption (others than provided by us) is not allowed during the entire study. Main study parameters/endpoints: Measurements will be performed during the run-in period (days 0, 11 and 14) and during the experimental period (days 56, 95 and 98). The main effects (egg-yolk and buttermilk consumption) will be calculated as the absolute differences between values obtained at the end of the experimental (average days 95 and 98) and run-in (average days 11 and 14) periods. The primary endpoint is the change in serum LDL cholesterol concentrations. Secondary endpoints are changes in serum total and HDL cholesterol, triacylglycerol, apoA-I, apoB and hsCRP concentrations.
NCT00934037
The purpose of this study is to evaluate the diagnostic accuracy of multi-detector computed tomography using 320 detectors for identifying the combination of coronary artery stenosis ≥ 50% and a corresponding myocardium perfusion defect in a patient with suspected coronary artery disease compared with conventional coronary angiography and single photon emission computed tomography myocardium perfusion imaging.
NCT03657823
An increasing proportion of women with heart disease now go through pregnancy and childbirth. More knowledge about the risk of complications and adverse outcomes for the mother and the baby is needed to guide clinical care in this diverse patient group. The purpose of this study is to, in a cohort of pregnant women with heart disease; * determine fetal growth, and risk of fetal growth restriction and preterm birth * determine whether maternal blood biomarkers are associated with development of preeclampsia, the time of delivery and maternal and perinatal adverse outcomes * determine the risk of hypertensive pregnancy complications The expected outcome of the project is to increase the knowledge of optimal diagnosis and treatment of women with heart disease that go through pregnancy to be able to improve clinical care and the outcomes for mother and baby.
NCT03512782
What is proposed in this project is to develop and evaluate the effectiveness of an online remote monitoring system that is easily accessible to patients so that professionals with experience in monitoring patients with heart failure (HF) can monitor signs and symptoms of decompensation of the disease, as well as self-care actions. A randomized, blind trial for outcome evaluation was designed that will include patients hospitalized for acute HF at a referral institution in cardiology in southern Brazil. Patients in the intervention group will be followed up with a remote monitoring system, accessible by device (computer, tablet and cell phone) connected to the internet, by checking for signs, symptoms and self-care actions in three moments during 30 days after hospital discharge. Patients in the control group will follow up according to the routine of the hospital or physician assistant. The primary endpoint for assessing the efficacy of the system will be hospital readmission within 30 days (follow-up period). The information regarding the signs, symptoms and self-care of the patients will be monitored by the research team through an access schedule. The sample calculation points to the need to include a total of 142 patients (71 in each group). The data will be analyzed through descriptive and analytical statistics. It is hoped that the development of a remote monitoring system could be characterized as a strategy for the early detection of signs and symptoms of acute decompensation in HF patients, impacting on hospital readmission rates within 30 days after discharge. In addition, remote monitoring of signs and symptoms may promote improved adherence and self-care of patients. The scientific contribution will occur to the extent to which there is innovation in patient follow-up and feedback obtained from the patient's interaction with the system.
NCT01866904
THis study is intended to provide contemporary data on the burden of disease in patients 1 to 3 years post-MI, including a description of patient characteristics, current treatment patterns, rate of major CV events, and healthcare resource utilization in a 'real world' patient population at high atherothrombotic risk.
NCT03655496
A novel home-based tool for self-management is to be evaluated for heart failure patients. The tool assists the patient with symptom monitoring, education and titration of diuretics. Patients who were recently hospitalized for heart failure will be randomized to receiving the tool or standard care for six months. The primary end-point will be self-care behaviour, as measured with the validated instrument the European Heart failure self-care behaviour Scale 9-item questionnaire (Jaarsma et al). Secondary end-points are in-hospital days due to heart failure, quality of life (general and disease-specific) as measured by the SF-36 and KCCQ questionnaires, and finally knowledge about heart failure, assessed by the Dutch Heart Failure Knowledge Scale.
NCT03653468
Despite exercise training decrease blood fasting glicaemy in 'average' terms, there is a wide inter-individual variability after exercise training explored mainly in adults but not in adults with prediabetes comorbidities. Thus, is yet unknown the effects and influence of the concurrent training (CT) eliciting responders (R) and non-responders (NR) cases (i.e., percentage of subjects who experienced a non-change/worsened response after training in some metabolic outcomes).
NCT00201162
To determine the effects of soy on lipids, lipoproteins and lipoprotein subclass in a sample of African-American and white postmenopausal women with low-density lipoprotein (LDL) cholesterol elevations that may increase their lifetime risk for cardiovascular disease but would not qualify for definite pharmacotherapy under current guidelines.
NCT03529253
The purpose of this study is to verify whether additional administration of Alirocumab exerts a stronger stabilizing effect on the vulnerable plaque in CAD, compared with statin alone administration in patients receiving PCI. Therefore, the change in maxLCBI (4 mm) of the coronary artery 9 months after administration by addition administration of Alirocumab is evaluated as the main evaluation item as compared with statin administration alone for patients who have CAD and received PCI. Also, change of plaque properties is compared with baseline and evaluated. This study is a single-center, randomized, open-label study, using alirocumab, rosuvastatin as test drugs. Based on the findings obtained in this study, it is possible to clarify the mechanism of stabilization of the plaque in a patient with coronary artery disease, which in turn suppresses the progress of plaque in coronary artery disease, resulting in primary or secondary There is a possibility that it can contribute to prevention.
NCT02923518
In 2010 there was published new European recommendations for assessment of adult and elderly men and women, who want to start with physical activity and/or participate in endurance contests. In this study we want to test if a group of people with positive score on a self-reported questionnaire and/or high-risk score in a risk scoring system (NORRISK) have more undetected heart diseases than a control group with no reported or detected risk factors.

Assess the relationship of Aortic root distensibility and stiffness with the extent of coronary artery disease as assessed by SYNTAX score compared to a matched cohort of patients with normal coronary angiography
NCT03646019
Coronary artery disease (CAD) is a major cause of death and disability in developed countries.Human studies revealed a significant association between serum oxidative status using PON1, TBARS and thiol levels and the presence of CAD and its severity. However, these studies were addressing the severity of CAD depending on coronary angiography of patients presenting with ST elevation myocardial infarction, Non ST elevation myocardial infarction, unstable angina pectoris, while part of them even had a history of CAD. Others where admitted for an elective coronary angiography for suspected stable CAD while only few patients were assessed for atypical chest pain. This study thus aims to assess the relationship between PON1 activity, TBARS and thiol levels and the existence of CAD and its severity in patients with no previous history of CAD presenting to the emergency department (ED) with acute chest pain but with no evidence of acute myocardial infarction or acute E.C.G ischemic changes. Assessment with a Cardiac CT scan instead of coronary angiography will allow the investigators to study the status of coronary atherosclerosis and calcium burden in all participants, including those presenting with atypical chest pain that most probably will not be referred by physicians to a coronary angiography. Further sub groups analysis will estimate this relationship particularly in low-intermediate risk groups depending on 3 different validated scoring systems - TIMI, GRACE and HEART score.
