Active clinical trials for "Coronary Artery Disease"

Phytosterols and ezetimibe each reduce intestinal cholesterol absorption by 30-55% but appear to have different mechanisms of action. The investigators' hypothesis is that phytosterols and ezetimibe given together will block cholesterol absorption in an additive fashion. In a randomized, placebo-controlled crossover trial the effects of placebo, ezetimibe treatment and ezetimibe plus phytosterol treatment will be measured.

A randomized control trial is planned to evaluate an interactive voice response (IVR) mediated follow-up and triage system, against usual care, to help smokers hospitalized with Coronary Heart Disease (CHD) to quit smoking. The investigators hypothesize that compared to usual care, participants in the IVR group will; a) have a significantly higher 7-day point prevalence abstinence rate at 26 and 52 weeks after hospital discharge, b) will have a higher rate of continuous abstinence at 26 and 52 weeks after hospital discharge, c) will use a greater number of proven effective interventions over time, and d) will develop greater self-efficacy with respect to smoking cessation, over time.

The purpose of this study is to determine whether comprehensive post-hospitalization interdisciplinary care management can be an effective care delivery model to improve outcomes in low-income frail elderly.

The purpose of this study is to investigate the impact of supraphysiologic oxygen (hyperoxia) on myocardial function in anaesthetized patients with coronary artery disease.

The effects of SGB on the cardiovascular system remain controversial since the cardiac sympathetic nerves pass through the stellate ganglion. SGB is expected to have an ameliorative effect on impaired coronary circulation and cardiac function and thus to be well suited to the treatment of angina pectoris and myocardial infarction

Sleep-wake disturbances were found to be a common problem among patients with CHD either earlier during hospitalization or/ and after discharge Although there is an evidence that sleep-wake disturbanes occur in high rate among patients with CHD little was found about assessment and management of this problem. This randomized controlled study will assess sleep quality of stable CHD patients who were admitted for undergoing coronary angiography electively. Then it will test the hypothesis that atlas cedar wood essential oil aromatherapy have a positive effect on sleep quality of CHD patients.

Flaxseed and olive oil consumption have beneficial effects on cardiovascular risk factors. Nonetheless the effects of their simultaneous consumption have not yet been studied.The purpose of this study is to investigate the effects of a healthy diet containing flaxseed and olive oil compared with healthy dietary advice on cardiovascular disease risk markers in patients with coronary artery disease (CAD), in improving flow-mediated dilation, plasma lipid profile and fatty acids composition of red blood cells.

Abstract Anaesthetic support for cardiac surgery significantly influences the course of the intraoperative period and the success of the postoperative period. Total intravenous anaesthesia and inhalation anaesthesia are the traditional methods of anaesthesia in cardiac surgery. However, there are few studies assessing the effectiveness of surgical aggression protection in cardiac surgery. Objectives: To study the effectiveness of body protection against surgical aggression by TIVA and inhalational anaesthesia in cardiac surgery. Materials and methods. The examination and treatment data of 89 patients were included in the study. All patients underwent coronary artery bypass grafting, mitral valve replacement/plasty, aortic valve replacement cardiopulmonary bypass conditions. The patients were divided into 2 groups according to the type of disease: the first (1) group with coronary heart disease. The second (2) group with valvular heart disease. There were 65 patients in the first group and 22 in the second. Both groups were divided into 3 subgroups according to the type of anaesthesia: patients anaesthetised with propofol, with sevoflurane, with isoflurane.

MACCHUS is a randomized, single-center, controlled, cross-over interventional study in which coronary artery resistances will be measured at baseline and during temporary occlusion of the coronary sinus.

Coronary artery disease and the benefit of bypasses: Despite considerable advances in medicine, cardiovascular diseases remain the number one cause of death globally, primarily consequence of myocardial infarction (MI). Coronary collaterals exert a protective effect by providing an alternative source of blood flow to a myocardial territory potentially affected by an acute coronary occlusion. Coronary collaterals represent pre-existing inter-arterial anastomoses and as such are the natural counter-part of surgically created bypasses. Sufficient coronary collaterals have been shown to confer a significant benefit in terms of overall mortality and cardiovascular events. In this regard, the concept of augmenting coronary collateral function as an alternative treatment strategy to alter the course of CAD, as well as to control symptoms, is attractive. Durable promotion of coronary collateral circulation: Before the advent of coronary artery bypass grafting, permanent augmentation of coronary collateral supply by a single structural modification has already been attempted. Bilateral ligation of the internal mammary arteries (IMA) was performed in CAD patients to alleviate angina pectoris and electrocardiographic (ECG) signs of ischemia. The prevalent in vivo function of natural IMA-to-coronary artery bypasses and their anti-ischemic effect has - for the first time - been recently demonstrated by our research group. The acute functional changes observed in response to temporary distal IMA balloon occlusion are expected to result in larger chronic structural adaptations of the IMA-to-coronary-artery connections when the distal IMA is permanently occluded. In contrast to the previously employed arteriogenic approaches in humans, the attractiveness of such an intervention lies in the potential durability of the effect. In a first step, catheter-based IMA occlusion ought to be conceptually investigated in the setting of the less frequently grafted right IMA among patients with ischemia in the right coronary artery territory.
