Active clinical trials for "Coronary Artery Disease"

To examine the role of social support in attenuating ischemic responses to psychological stress, both in the laboratory and during daily life.

The study of biochemical risk factors for cardiovascular diseases is important not only for analysis, but also for preventive measures, given that changes in the level of biomarkers can be detected before the first clinical manifestations of CVD. Accordingly, patients at high CV risk may have additional motivation to lead a healthy lifestyle. In addition, information on biochemical risk markers can be used to optimize the clinical management of patients.

18F-FMPP is a novel PET myocardial perfusion imaging (MPI) tracer which targets to mitochondria complex I (MC-I). Preclinical animal studies have shown that its uptake is highly uniform and long in the heart and rather low in the liver. It may be a promising tracer for myocardial perfusion imaging. In addition, as a myocardial PET tracer, it is capable of quantifying absolute myocardial blood flow. Thus this prospective and open-label study is going to evaluate the diagnosis performance of 18F-FMPP PET MPI in suspected or known CAD patients who will be referred for invasive coronary angiography (ICA).

Ischemia-guided revascularization is the cornerstone of contemporary management of coronary artery disease (CAD). Coronary physiological assessment is advocated in the catheter laboratory to guide percutaneous coronary intervention (PCI), and it is widely accepted that an FFR ≤ 0.80 is a good indicator for vessels to benefit from revascularization. Nevertheless, a significant proportion of PCI patients continue to experience adverse events related to both stented segment and/or residual or diffuse disease. Our group recently demonstrated the feasibility of pullback pressure gradient (PPG) derived from virtual Quantitative Flow Ratio (QFR) pullback curve, which is an index of atherosclerosis functional pattern and can be used to epitomize the pathophysiological pattern of CAD as focal or diffuse. In this regard, the current study will investigate the incremental value of PPG added to QFR haemodynamic assessment in ischemia-causing vessels received PCI in predicting adverse outcomes.

Patients with STEMI and multivessel disease in whom the culprit lesion has been successfully revascularized during prmimary PCI, will be randomized to in-hospital or after-discharge complete revascularization. The purpose of this study is to evaluate the impact of these two different strategies in terms of hospital stay.

The quality of life, linked to physical, social and mental performance in people with coronary heart disease represents the primary goals in terms of rehabilitation. This is often developed to meet the expected performance standard in order to give the person effective autonomy. However, is the occupational balance always evaluated? and this management adapted? Does occupational therapist, expert in autonomy and independence in multiple illnesses and disabilities, has a major role to play in cardiac rehabilitation? This area of expertise and the application of occupational therapy to coronary patients seems appropriate, if not necessary. However, there are few scientific studies on the need to include occupational therapy within cardiac rehabilitation protocols.

The presence of chronic blockage of coronary arteries, which we may accept as the terminal point of atherosclerotic coronary artery disease, is closely associated with a poor prognosis. The Discovery of markers that may distinguish patients with a high risk of chronic total occlusion development among patients monitored with the diagnosis of stable coronary artery disease may be important for being able to reduce the increased mortality and morbidity rates. Oxidative stress status may be one of the markers that play a role in and/or show the development of chronic total occlusion. It was reported that it has a role in the progression, erosion, and instability of atherosclerotic plaques in coronary arteries. To the best of our knowledge, the relationship between chronic total occlusion development and oxidative stress status in stable coronary artery disease has not been studied. This study investigated the relationships in the oxidative stress status evaluated over TAS, TOS, OSI, Thiol/Disulfide Homeostasis, and antioxidative vitamin levels and possible differences in patients with noncritical coronary artery disease and those with chronic total occlusion.

Cardiovascular disease, and in particular ischemic heart disease, is the main cause of morbidity and mortality worldwide today (1). Myocardial infarction (MI) presents the most serious clinical entity through its short-term life threatening involvement. The many advances in the management of IDM during the acute phase, namely the increasingly frequent and effective use of reperfusion means (angioplasty and thrombolysis) as well as pharmacological progress, in particular, the management of anti-thrombotic treatment has enabled a significant reduction in intra-hospital mortality, in the medium and long term (2). In fact, the mortality rate dropped from 25-30% before the creation of the cardiac intensive care units (ICUS) around the 1960s, to around 16% in the 1980s and reaching 4 to 6% today. In the latest data from the French FAST MI 2015 register (French Registry of Acute ST-Elevation or Non-ST-elevation Myocardial Infarction) mortality was 2.8% in hospital (3) and 5.3% at 6 months (4). Nevertheless, mortality rates diverge from one register to another and are generally higher compared to randomized controlled clinical trials. In our country, due to the aging of the Tunisian population (currently the oldest population in Africa), as well as the rise in the prevalence of cardiovascular risk factors (5), the incidence of IDM is clearly increasing. However, our local specificities concerning the management of this pathology and the intra-hospital mortality which results from it, remain little described despite the importance of these data in the development of personalized algorithms and the improvement of the quality of this support. the management of CAD ST + in the public sector poses more and more efficiency problems and moves away from international recommendations in our country, an assessment of our national situation is necessary. The objectives of the study are, primary, the incidence of new cases that consult the emergency room for CAD ST + and the treatment delivered to the emergency room, in particular the nature of the treatment for obstruction (primary angioplasty or thrombolysis). Secondary, the evaluation of hospital complications and the future of patients on D30 and after one year from the inclusion's day.

To assess diagnostic accuracy,image quality and renal safety of a double low-dose coronary CTA protocol at coronary artery evaluation in patients with diabetes by using invasive coronary angiography(ICA) as the reference method and to compare the results with those obtained traditional dose protocol. The study will randomly include about 400 consecutive participants aged 18 to 80 years old who had been diagnosed with diabetes and suspected coronary artery disease.All participants undergo ICA and coronary CT angiography performed with a whole-heart CT scan.Coronary segment interpretability,image quality based on a four-point Likert scale,blood indicators of renal function will be accessed between double low-dose CTA protocol and traditional CTA protocol. Investigators hypothesize that an individualized coronary CTA protocol that appropriately reduces radiation dose and contrast dose does not affect image quality and diagnostic accuracy, and can reduce the risk of kidney damage in high-risk patients.

The purpose is to observe and evaluate the safety and efficacy of Bingo drug-coated balloon in the real world.
