Filter by:In Patients with stable Angina pectoris CCS 1-3 exercise testing for ischemia detection is widely used despite the known limitations. Measurement of the FFR is invasive but gold standard for Ischemia detection. Adding of parameters of spiroergometer might help to improve diagnostic accuracy of non invasive exercise testing. Therefore the trial is evaluating diagnostic accuracy of spiroergometric parameters compared to invasive FFR measurement.
The "DATASET-PRECISE", a 3-arm parallel randomized study, aims to provide new insights in risk stratification of patients with suspected CAD in the Greek population. The convergence of information derived from exercise ECG stress test, CACS, CCTA and metabolomic profiling in artificial intelligence algorithms describes in brief the main objective of this protocol. The design of the present proposal is based on current state-of-the-art literature, incorporating, however, additional innovative elements. It is about the first randomized study to be conducted in Greece, investigating the role of CCTA and CACS in CAD diagnosis and risk assessment. Moreover, the present protocol aims to integrate information on patients' metabolomic profiling. The process of the whole information by using artificial intelligence technology will lead to the development of new risk stratification algorithms, promoting further personalized diagnostic and therapeutic approach. Regarding Greece, this is the first prospectively enrolling medical database of this scale.
Bifurcation lesions (BL) on coronary arteries account for 15-20 % of all performed percutaneous coronary interventions (PCI). Preferred approach for treatment of most bifurcation lesions is the stepwise provisional stent strategy with main branch-only stenting followed by provisional balloon angioplasty with or without stenting of the side branch (SB). Stenting of the side branch is indicated when the angiographic result in SB is clearly suboptimal and when flow remains reduced. Upfront use of two stent techniques may be indicated in very complex lesions with large calcified side branches ( most likely to supply at least 10% of fractional myocardial mass), with a long ostial side branch lesion (>5mm) or anticipated difficulty in accessing an important side branch after main branch stenting, and true distal LM bifurcations. From a technical point of view, we propose a "Provisional DCB approach" that differs from the standard provisional approach with obligatory SB predilation and good lesion preparation. In case of an adequate result of predilation, the procedure on the SB ends with the DCB deployment. This is followed by main branch stenting with DES, finished with POT. Final 'kissing' balloon dilation is generally not recommended because there is no advantage from final kissing with the one-stent technique. With this approach, there is no need for re-wiring, re-ballooning, side branching and wire jailing and final kissing. This technique is close to a contemporary approach to bifurcation lesions based on the fundamental philosophy of the European Bifurcation Club (EBC): keep it simple, systematic, and safe, with a limited number of stents that should be well apposed and expanded with limited overlap, with respect of the original bifurcation anatomy.

Imaging the inside of coronary arteries (intravascular imaging) offers great insight into the assessment and treatment of coronary artery disease. Over time, substances such as fat, cholesterol and calcium can build up into 'plaques' in the arteries, causing narrowings or even blockages. These plaques can also rupture, causing cardiovascular events such as heart attacks or strokes. By using ultrasound and infrared technology, intravascular imaging can help assess these plaques, however this is an invasive technique involving angiography. Plaque composition, structure and stability can be affected by inflammation and the stress that the arteries are under. The investigators have pioneered novel minimally-invasive methods for modelling arterial stress using computed tomography coronary angiography (CTCA), as well as imaging coronary arterial inflammation using a positron emission tomography (PET) scan. Before embarking upon a large-scale clinical outcome study to determine whether these novel methods can improve risk prediction, the aim is to perform a proof-of-principle study to further develop our methodology for hybrid image analysis, and to validate this technique against high-resolution intravascular imaging as a surrogate marker of histology.
The purpose of this study is to investigate the potential association of coronary artery geometry, based on coronary CT angiography (CCTA), with the complexity and the severity of coronary atherosclerosis.
This study, designed as a retrospective registry, aims to investigate the relationship and potential interplay between fractional flow reserve (FFR) or instantaneous waves free ratio (iFR) with wall shear stress (WSS) in the context of intermediate coronary stenosis.
Coronary artery disease (including stable angina and acute coronary disease) remains the leading mortality and morbidity worldwide. Improvement in biomarker, imaging research have led to new predictors for the prognosis, which may have great clinical value in the current era of personalized medicine. However, there is no available biomarker-based prediction rule for risk assessment of adverse events in patients with stable angina and acute coronary disease. Therefore, we aim to develop and validate a new biomarker-based risk model to improve the prognostication of adverse events (e.g. ischemic and bleeding events ) in the patient population.
Patients aged 18-89 with stable CAD and comorbidities receiving optimal medical treatment requiring PCI with iodinated contrast media. The aim of the study is to assess the prevalence of contrast-induced AKI in 2012-2013 and 2017 cohorts and to evaluate the potential risk factors of CI-AKI to better guide the prevention in patients of higher risk.
