Filter by:The study is a randomized, double-blind, placebo-controlled (corn oil), parallel group design that will enroll approximately 13,000 patients with hypertriglyceridemia and low HDL and high risk for CVD to be randomized 1:1 to either corn oil + statin or Epanova + statin, once daily, for approximately 3-5 years as determined when the number of MACE outcomes is reached.
Cardiovascular disease (CVD) is the leading cause of death in the US. Statistics show that approximately 91% of individuals with CVD have vascular dysfunction. Hypertension is a major modifiable risk factor for CVD and approximately 60% of adults in the US are pre-hypertensive and hypertensive. In addition, the prevalence of hypertension is associated with aging in both genders; however, the increase in blood pressure (BP) in women after menopause exceeds that of men. The development of effective and safe strategies to improve vascular function is of significance as it can have a great impact on quality of life, productivity and economic burden for the affected populations. One such alternative would be to introduce into the diet food sources that are rich in naturally occurring bioactive compounds. Thus, the long-term goal of the investigators is to provide feasible and effective dietary ways for postmenopausal women to improve their vascular function and quality of life. Strawberries are a rich source of bioactive compounds and its total antioxidant content ranks third among all fruits and vegetables. Hence, the purpose of this study is to bring forth evidence that incorporation of strawberries into the diet will reduce blood pressure and improve cardiovascular function in pre- and stage 1-hypertensive postmenopausal women. Sixty eligible postmenopausal women between the ages of 45 and 65 and a seated BP of ≥ 130/85 mm Hg but ≤ 160/100 mmHg at the screening visit will be randomly assigned to one of three groups: 1. 25 g freeze-dried strawberry powder; 2. 50 g freeze-dried strawberry powder; or 3. placebo powder. Participants will be asked to consume the supplements for 8-weeks. Medical history, medication use, dietary intake, and physical activity will be assessed at 0-, 4-, and 8-weeks followed by blood draw. Serum levels of markers of cardiovascular function as well as oxidative stress and inflammation will be measured. The investigators hypothesize that regular consumption of strawberry will improve cardiovascular function, decrease BP and blood markers of oxidative stress as well as inflammation. Investigators also expect the findings of this study to provide a foundation for further studies to examine the effects of long-term incorporation of strawberry into the diet and the integrity of cardiovascular system.
An evaluation of the safety and performance of the STANZA Drug-eluting Resorbable Scaffold (DRS) system for the treatment of patients with obstructive superficial femoral artery disease.
High density lipoprotein cholesterol (HDL-C) is in the centrum of the process of reverse cholesterol transport from peripheral cells to the liver[10]. HDL-C promotes endothelial generation of nitric oxide (NO) and improves endothelial function and arterial vasoreactivity[11]. In several studies, lower HDL-C level was reported to be associated with increased coronary artery disease (CAD) risk[12-14]. HDL-C also has anti- inflammatory and anti-oxidant activities[15,16]. Concerning anti-inflammatory activity, HDL-C inhibits the activation of monocytes/macrophages and neutrophils[17,18] and inhibits the expression of endothelial adhesion molecules, such as vascular cell adhesion molecule-1 (VCAM-1) and E-selectin[15]. In this study we aimed to investigate the relation of HDL-C level with systemic inflammatory markers in patients with cardiac syndrome X (CSX).
The purpose of this study is to assess safety and efficacy of Ticagrelor versus Clopidogrel in Asian/KOREAn patients with acute coronary syndromes intended for invasive management.
The aim of this study is the comparison between the effects of supplementation with omega 3 or placebo for 8 weeks in serum level of IGF-1 and IGFBP-3 and gene expression of IGF-1 in patients with cardiovascular disease.
Evaluation of the metabolic and physiological characteristics of patients with diagnosed Cardiovascular Disease following administration of the Cardiovascular vitamin, CardioLife.
Rationale: Despite successful efforts to lower atherogenic serum low-density lipoprotein (LDL) cholesterol concentrations, a substantial residual cardiovascular risk is still present. An additive strategy to further lower this residual risk may be via raising high-density lipoprotein (HDL) cholesterol concentrations, and in particular those of its major protein constituent apolipoprotein A-I (apoA-I). However, recent evidence shows that raising HDL cholesterol (HDL-C) concentrations not always causes a reduction in cardiovascular disease (CVD) risk. To understand this it is important to know what are the targets and molecular mechanisms that underlie a shift to a HDL fraction with cardioprotective activities. There is increasing evidence that particularly the apoA-I proteins in the HDL fractions are atheroprotective. It is important to verify whether the effect of an intervention actually increases apoA-I production since that results in the formation of de-novo small pre-beta HDL particles that have full capacity to resorb cholesterol from the arterial wall and return this to the liver for secretion (reverse cholesterol transport). The investigators here propose to evaluate, in a double-blind human intervention study, the difference in intestinal apoA-I gene expression, of healthy subjects, after consumption of a high fat (HF) or low fat (LF) meal. Additionally the investigators propose to evaluate the effect of theobromine on intestinal apoA-I expression. Based on several studies, theobromine improved cardiovascular risk parameters among which an elevation in apoA-I and HDL cholesterol concentrations. It is however unknown whether this effect of theobromine originates from elevated apoA-I production, which suggest improved functionality, or decreased clearance, suggesting reduced functionality. The investigators therefore propose to also evaluate if the usage of theobromine is a better way to increase intestinal apoA-I mRNA and protein expression, than consumption of a HF meal. The investigators will do this in the same double-blind human intervention study. The theobromine will be added in a third arm in a LF condition. Study design: The proposed study will have a randomized, double-blind cross-over design. The total study duration will be 17 days, consisting of 3 experimental days with postprandial tests, each separated by a 1 week wash-out period. Study population: Ten apparently healthy male subjects, aged 18-60 years, without a history of any gastrointestinal disorders or complaints. Intervention: During the three experimental days, subjects will consume a milkshake: one HF milkshake, one LF milkshake and one LF milkshake supplemented with 850 mg theobromine. Total follow-up during each of the postprandial tests is 5 hours.
The objective was to compare the frequency and intensity of symptoms of anxiety in patients of preoperative cardiac surgery who received empathic behaviour from nurse or family or those who received no specific type of empathic behaviour. This is a randomized clinical trial. The sample consisted of 66 patients in preoperative of cardiac surgery, who were divided in three groups: empathic behaviour by nurses, without specific empathic behaviour and by family. Anxiety was assessed at two time points: before and after the intervention. The instrument used was developed and validated, comprising 19 defining characteristics of the nursing diagnosis anxiety. The hypothesis is that the group who received empathic behaviour from nurse or family will reduce the anxiety.
Cardiovascular diseases (CVD) are still considered the main cause of mortality and morbidity all over the world. In the last years, efforts have been made to define more effective therapeutic and preventive strategies.Periodontal diseases have been considered a probable risk factor for CVD with a great amount of evidence from observational studies. Although there are some interventional studies evaluating the systemic effects of periodontal therapy, there is little information regarding the impact of periodontal treatment on the prevention of cardiovascular events. To the best of our knowledge, there are no randomized controlled trials published to date assessing the effect of periodontal therapy in primary prevention of CVD.
