Multicenter Registry of Coronary Flow-Derived Indexes (MulticenterFLOW)

Coronary Microvascular DiseaseCoronary Artery Disease1 more

MulticenterFlow is a prospective, multi-center, registry study. The aim of the study is twofold: To evaluate prognostic implications of coronary microvascular disease (CMD) in patients with ischemic heart disease (IHD) undergoing revascularization decision using fractional flow reserve (FFR) or other non-hyperemic pressure ratios in deferred population To evaluate the efficacy of intravascular imaging-guided optimization to enhance post-revascularization coronary circulatory function, compared with angiography-only guided revascularization in revascularized population.

Parenteral Antiplatelet Agents in Real-world Spanish PCI Patients

Ischemic Heart DiseaseAcute Coronary Syndrome

This registry will provide exploratory and descriptive information regarding contemporary practice patterns of parenteral antiplatelet therapy in the PCI (Percutaneous Coronary Intervention) setting and will investigate as well the short-term effectiveness and safety of the currently available parenteral antiplatelet agents in a cohort of "real-world" patients undergoing PCI in Spain.

Coronary Artery Disease

This is a hospital-based registry study that will be to describe clinical and paraclinical features, procedural-related characteristics, short and long-term outcomes, hospital costs of patients undergoing percutaneous coronary intervention (PCI) at University Medical Center of Ho Chi Minh City (UMC), together with investigating predictors for patients' adverse clinical outcomes. The specific objectives of this study are: To validate a framework/model of PCI registry in UMC To investigate the demographic, clinical of cardiovascular diseases and procedural characteristics of patient undergoing PCI in UMC To investigate the procedural success, in-hospital adverse events and patient outcomes at one-month, three-month, twelve-month, three-year and five-year follow-up after PCI in UMC To estimate in-hospital and procedural costs associated with PCI in UMC To develop a prognostic prediction model for patients after PCI in UMC

Coronary Artery DiseasePercutaneous Coronary Intervention1 more

In this prospective, multicenter observational study, The investigators evaluated the safety and effectiveness of DAPT over 1 year in all patients with coronary artery disease, including patients with complex high-risk coronary artery disease (CHIP), who underwent PCI using the Genoss DES stent, and performed subgroup analysis. Through this, the investigators aim to determine whether there are differences in safety and effectiveness depending on whether or not the patient is a subject with complex high-risk coronary artery disease.

DCB Treatment in CTO Guided by IVUS

Coronary Artery Disease

The percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) coronary artery disease is difficult, the success rate is low, and the incidence of re-occlusion and restenosis is high. With the wide application of imaging technology represented by intravascular ultrasound (IVUS), the success rate of CTO PCI has been significantly improved. Drug-coated balloons (DCB), as a treatment without metal implantation, has lower lumen loss and no significant increase in the rate of revascularization. Through IVUS measurement of vascular lumen after CTO opening, appropriate instruments can be selected for adequate dilation, and appropriate treatment methods can be selected according to different lumen structures. Therefore, the purpose of this study was to evaluate the clinical effect of IVUS-guided DCB therapy on CTO lesions.

Coronary Microcirculatory Disease and Inflammation in Patients With Chronic Coronary Syndrome and...

Coronary Artery DiseaseIschemia and No Obstructive Coronary Arteries3 more

Patients with chronic coronary syndromes (CCS) diagnosed without significant lesions in invasive coronary angiography (ischemia non-obstructive coronary artery disease - INOCA) represent approximately 50% of all patients with CCS. Results of FAME study clearly showed that evaluation of coronary circulation should not be accomplished only with visual assessment in resting conditions. Current European Society of Cardiology Guidelines of diagnosis and treatment of CCS published in 2019 emphasize the necessity of performing complex coronary physiology assessment. Invasive physiological measurements and vasoreactivity provocative tests emerged as key tools to differentiate between vasospastic angina, microcirculatory angina, overlap of both conditions or non-cardiac disease. According to contemporary literature, identification of heterogeneity of patients with INOCA is crucial for determination of adequate treatment. An appropriate pharmacotherapy has a potential to improve outcomes including grade of angina, quality of life, exertional tolerance and most important - MACCE (major adverse cardiac and cardiovascular events) free survival. However, there is a lack of evidence on each of the subtypes of INOCA especially in those with signs and symptoms of vasospasm in provocative test but without visual spasm in epicardial vessels.

Tilburg Health Outcomes Registry of Emotional Stress in Coronary Intervention

Coronary Heart Disease

Background of the study: Percutaneous coronary interventions (PCI) have become mainstay treatment for acute coronary artery disease and the number of patients receiving PCI is vastly growing. However, relatively little long-term follow-up studies of large real-world clinical samples exist that have looked at the real-world effects of PCI treatment and adherence to current guidelines. Psychological risk factors are important in determining prognosis after PCI, and undergoing PCI may increase the risk of low mood. To date, studies have examined single psychological risk factors, without taking into account their relatedness. Moreover, guidelines are advocating psychosocial screening in early cardiovascular disease, but the screening test as proposed in the prevention guideline has not yet been validated or tested. Although the detrimental effects of psychological risk factors on cardiovascular prognosis are known, the mechanisms through which they exert these effects are yet unclear. It is to be expected that not one but multiple biological (inflammation, endothelial dysfunction) and behavioural (coping styles, poor self-care, consultation behaviour) pathophysiological processes play a role, and that these processes interact with each other. In PCI patients the mechanisms linking psychological risk to poor prognosis are still to be investigated. Objective of the study: To examine the adherence to the prevention and PCI guidelines and the effects thereof on long term prognosis in PCI patients. To evaluate the effectiveness of the psychosocial screening instrument of the European Society of Cardiology Prevention guideline 2012. To examine effects of clustering psychological risk factors on several networks of potentially mediating mechanisms and long term outcomes in a large sample of PCI patients.
