Diagnostic Values of Galectin-3, Soluble ST2 and BNP in Predicting the Clinical Outcome of ST-Segment Elevation Myocardial Infarction Patients

Start date: March 1, 2022
Phase:
Study type: Observational

An acute ST-elevation myocardial infarction occurs due to occlusion of one or more coronary arteries, causing transmural myocardial ischemia which in turn results in myocardial injury or necrosis. Acute myocardial infarction (AMI) may lead to the development of heart failure (HF). Accessible diagnostic tools commonly used in HF such as natriuretic peptides and (NYHA) classification reflect already overt clinical HF. Troponin and creatine kinase reflect myocardial damage, but their usefulness in predicting long-term LVR is limited. Recent guidelines on HF management stressed that HF onset may be delayed or prevented through certain Interventions, such as pharmacotherapy ,post infarction rehabilitation, or modification of HF risk factors. Therefore, it is important to identify potential markers, which would be more informative of HF preclinical stages to recognize patients with an increased risk of HF onset, and to start treatment in advance (1) Gal-3 participates in inflammation and pro fibrotic pathways, while sST2 is a biomarker of inflammation, cardiac mechanical strain, and tissue fibrosis, both of which may predict LVR (2). sST is a biomarker of inflammation, cardiac mechanical strain, and tissue fibrosis(3). B_type natriuretic peptide (BNP) is elevated in acute myocardial infarction and is a quantitative biochemical marker related to the extent of infarction and left ventricular systolic dysfunction(4).

CCTA, CACS and ECG Stress Testing in Patients With Suspected CAD: Precision Phenotyping and Financial Evaluation

DATASET
Start date: January 1, 2021
Phase: N/A
Study type: Interventional

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.

Drug Coated Balloon for Side Branch Treatment vs. Conventional Approach in True Bifurcation Coronary Disease: PRO-DAVID

PRO-DAVID
Start date: October 2020
Phase: N/A
Study type: Interventional

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.

Development and Validation of a Fast, Semi-Automated Hybrid Imaging Platform to Assess Coronary Atherosclerotic Plaque Morphology, Endothelial Shear Stress and Arterial Inflammation: A Proof of Principle Study (VALID-PET-CT)

VALID-PET-CT
Start date: January 1, 2020
Phase:
Study type: Observational

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.

NCT ID: NCT02574949 Not yet recruiting - Clinical trials for Acute Coronary Syndrome

Impact of Low Frame Rate Fluoroscopy and Cine-angiography on Reducing Operator and Patient Dose

Start date: July 2015
Phase: N/A
Study type: Interventional

The investigators sought to investigate the efficacy of low frame rate (fluoroscopy at 7.5 frames per second (FPS) and Cine at 10 pulse per second (PPS) vs. conventional (15 FPS and 15 PPS) on radiation dose to the patient and the operator during coronary angiography and intervention. In addition, investigators sought to qualitatively assess the effect, if any, of the low frame rate on angiographic image quality.
