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 primary objective of this study is to build a repository of resting cardiac phase space signals from eligible subjects using the Phase Signal Recorder (PSR) prior to coronary angiography for the purposes of machine-learning and testing algorithms developed by Analytics 4 Life. Male and Female subjects will be uniquely and consecutively enrolled into one group to support populating a repository of phase signals.

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.

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

Coronary physiologic assessments by the pressure-derived fractional flow reserve (FFR) have become standard methods for identifying hemodynamic deprivation in coronary arterial stenosis for evidence-based percutaneous coronary intervention (PCI). Invasive physiologic indices-guidance enables on-site real time assessment for functional significance of epicardial coronary stenosis and the use of those indices has shown to be effective to guide treatment decision. Several studies further support the role of post-PCI FFR measurement as a functional marker of residual disease after PCI and prognostic indicator of patients. Although optimal cut-off values of post-PCI FFR varied across studies, an inverse relationship between post-PCI FFR and the risk of future clinical events have been reported consistently. Recently, non-hyperemic pressure ratios (NHPRs) have been introduced in clinical practice. Although there are several different NHPRs, previous studies consistently indicated that those NHPRs shares similar diagnostic performance and prognostic implications. Nevertheless, few reports were available for clinical relevance of NHPRs in evaluation of post-PCI status. In this context, we will evaluate the physiologic characteristics and prognostic implication of post-PCI NHPRs and compare with those of post-PCI FFR in patients who underwent angiographically successful PCI with 2nd generation drug-eluting stent implantation (DES).

The objective of this study is to retrospectively gather information on patients who underwent a CIED procedure with either a CanGaroo Envelope, TYRX Envelope, or no envelope.

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 of this study is to prospectively observe the incidence rate of acute kidney injury (AKI), major adverse renal and cardiovascular events (MARCE) in participants who were diagnosed with ST-segment elevation myocardial infarction (STEMI) and have completed primary percutaneous coronary intervention (PCI) procedure following an injection of iso-osmolar contrast medium iodixanol (Visipaque) during the in-hospital period and up to 30 days post-PCI follow-up period. The study will provide a better safety profile of Visipaque as the contrast medium in PCI procedure.

Study objective - to assess the efficacy, tolerability and adherence of bisoprolol/perindopril FDC in patients with HT and stable CAD in everyday practice. Type of the program: multicenter, observational, uncontrolled, open program. The program will involve 480 general practitioners (GPs) and cardiologists from the primary care facilities.Each doctor includes four patients. It is planned to include not less than 1920 patients in total.

The expression and quantification of Micro-RNA 146-a, was analyzed in the subgingival plaque samples of generalized chronic periodontitis patients with and without coronary heart disease. The demographic variables and periodontal parameters were assessed and correlated with expression of micro-RNA 146-a. The quantification of levels of micro-RNA 146-a was done using Real time Polymerase chain reaction. ( RT-PCR)
