Inflammation and Clotting Abnormalities in Aneurysmal Coronary Artery Disease
Coronary Artery AneurysmAbdominal Aortic Aneurysm1 moreThe main objective of the CARE-ANEURYSM project is to evaluate inflammation and clotting abnormalities in patients with aneurysmal coronary artery disease in relation to patients with abdominal aortic aneurysm or coronary artery disease (acting as controls).
Evaluation of the Benefit of Exercise Testing for the Diagnosis of Obstruction in the Coronary Arteries...
Coronary Artery DiseaseThe purpose of this study is to determine whether exercise testing can detect an obstruction in a coronary artery, and, thereby, can avoid performing a coronary imaging in some cases. Patients with a suspicion of coronary artery disease perform an exercise test on an exercise bike with increasing load. EKG, blood pressure, and other parameters are monitored. Patients benefit also of either a cardiac CT scan or a coronary angiography to establish whether they really have coronary obstruction.
Neural Interfaces to Monitor Fatigue and Sleepiness in the Cathlab
Coronary Artery DiseaseMental Stress2 moreImprovement of patients' care and outcome is largely based on development and validation of drugs and technologies, especially in rapidly evolving fields as Interventional Cardiology. In fact, even though the optimal efficiency of a cathlab can be influenced by Interventional Cardiologist's mental workload, stress' accumulation and performance, little if any attention is paid to the monitoring and optimization of his/her mental status. Electroencephalogram (EEG)-based neural-interfaces are able to estimate workload, fatigue and the degree of sleepiness through spectral analysis techniques. In particular, the amplitude of alpha waves is a widely validated indicator of mental engagement's level. Developing a low cost and highly feasible device to monitor and analyze operator's mental engagement level and performance could be extremely appealing, especially considering both the lack of data in literature for interventional disciplines and the recent technology developments.
PericOronary INflammaTion in Non-Obstructive Coronary Artery Disease
Non-Obstructive Coronary AtherosclerosisAmong patients with ischemic heart disease who are referred for coronary angiography, a substantial proportion have non-obstructive coronary artery disease (CAD). Myocardial infarction (MI) with non-obstructive coronary artery disease (MINOCA) accounts for 5-20% of patients with MI and preferentially affects women. MINOCA pathogenesis is varied and may include atherosclerotic plaque rupture, plaque erosion with thrombosis, vasospasm, embolization, dissection or a combination of mechanisms. Other patients may have clinically unrecognized myocarditis, or takotsubo syndrome masquerading as MI. Among patients referred for coronary angiography for the evaluation of stable ischemic heart disease, non-obstructive CAD is present in up to ~30% of men and ~60% of women. Stable ischemia with non-obstructive coronary arteries (INOCA) may be due to coronary microvascular dysfunction in up to 40% of these patients. Our understanding of mechanisms of MINOCA and INOCA remain incomplete. Coronary inflammation has been hypothesized as a potential mechanism contributing to coronary spasm in MINOCA and microvascular disease in INOCA.
WARRIOR Ancillary Study for CCTA Analysis
Coronary Artery DiseaseNon-Obstructive Coronary Atherosclerosis1 moreIn this study, quantitative characterization of plaque using coronary computed tomographic angiography (CTA) will be used to determine if women who were treated with intensive medical therapy have a greater reduction in the amount and type of cholesterol plaque compared to women receiving usual care and if this results in beneficial changes in clinical symptoms. The study will provide an understanding of how intensive medical therapy works in providing clinical benefit in women with nonobstructive plaque.

Additive Value of Physiology Coronary in Clinical Practice
Microvascular Coronary Artery DiseaseThe important evidence of coronary microcirculation for the management of patients with coronary artery disease is only increasing. Thus, in recent years, a number of studies have shown that the demonstration of coronary microvascular disease (CMVD) contributes to cardiovascular morbidity and mortality increases independently of epicardial damage. This has been shown in stable coronary artery disease with screening for CMVD when there is no significant epicardial involvement and allowing the implementation of an adapted treatment then reducing the symptoms and improving the quality of life of our patients. (1). The prognostic nature of CMVD has also been identified in stable disease after coronary angioplasty (2) but also in patients with infarcts reperfused by coronary angioplasty (3). The complete exploration of the epicardial and microvascular coronary vascularization is grouped under the name of the subspecialty: coronary physiology. Thus, an internationally recognized algorithm for exploring coronary physiology has been published (4). However, this algorithm is still little followed. The PRINCIPE registry aims to assess the prevalence of CMVD with the use of a standardized algorithm for exploring coronary physiology by coronary angiography in our center in current practice.
Usefulness of Coronary Computed Tomography Angiography for Therapeutic Decision- Making; Revascularization...
Coronary Artery DiseaseIschemic Heart DiseaseAs the prospective, observational, cross-sectional study, the accuracy of CT angiography-based therapeutic decision-making for revascularization will be evaluated. The primary objective of this study is to evaluate the accuracy of CT angiography-based therapeutic decision-making for revascularization prior to conventional angiography whether CT angiography is an accurate non-invasive technique to determine the most appropriate therapeutic strategies.
