NCT ID: NCT03739073 Recruiting - Clinical trials for Coronary Artery Disease

Can we Predict COronary Resistance By EYE Examination ? (COREYE)

COREYE
Start date: October 4, 2018
Phase: N/A
Study type: Interventional

Prospective interventional study, open, non-comparative and non-randomized. The research concerns physiological parameters of the coronary and ocular blood circulation. At the coronary level, the curves of pressure and Doppler flow will be extracted from ComboMap® (Philips). The coronary microvascular resistances, basal and hyperemic, will be determined by the average ratio of the distal pressure and flow. At the ocular level, a fundus oculi and an OCTA (angiography by tomography in optical coherence) examination will be performed. The measures of the FFR and the coronary microvascular resistance will be determined by a specific guidewire allowing simultaneous measures of pressure and Doppler flow (ComboWire®, Philips), in 200 patients with intermediate stenosis of the left anterior descending artery (LDA). Topological parameters characterizing the retinal area and choriocapillaires will be determined by statistical approaches and mathematical morphology. To establish a predictor of the coronary microvascular resistance from the eye vascular parameters, we shall use a non-linear regression by supervised machine learning. The main cardiovascular risk factors (hypertension, diabetes, dyslipidemia, age, sex) will be part of predetermined input features for the machine learning.

RETO 320
Start date: January 15, 2019
Phase:
Study type: Observational [Patient Registry]

This prospective registry is intended to evaluate the safety and efficacy of the Optimax® stent.

NCT ID: NCT03736018 Not yet recruiting - Clinical trials for Contrast-induced Nephropathy

Randomised Controlled Trial to Assess Whether Computed Tomography Cardiac Angiography Can Improve Invasive Coronary Angiography in Bypass Surgery Patients

BYPASS-CTCA
Start date: November 8, 2018
Phase: N/A
Study type: Interventional

A large number of patients with symptomatic ischaemic heart disease undergo coronary artery bypass grafting (CABG) to alleviate their symptoms and improve prognosis. Given the progressive nature of coronary disease, bypass grafts can narrow or block over time, leading to chest pain and the need for further invasive coronary angiography. Invasive coronary procedures in patients with bypass grafts can be more complicated due to the variation in bypass graft ostia. This can lead to longer procedure times, with higher doses of contrast and radiation and more discomfort for the patient. The aim of this study is to see if the use of computed tomography cardiac angiography (CTCA) in patients with previous bypass grafts prior to invasive coronary angiography will help make their procedure safer and quicker.

NCT ID: NCT03735186 Completed - Inflammation Clinical Trials

Exercise and Coronary Heart Disease Risk Markers in Male Smokers and Non-Smokers

Start date: August 4, 2017
Phase: N/A
Study type: Interventional

The present study will investigate the effect of acute exercise on fasting and postprandial risk markers for coronary heart disease (CHD) in healthy male cigarette smokers and non-smokers. Participants will complete two, 2-day trials in a random crossover design separated by an interval of at least 1 week. On day 1, participants will rest (control) or complete 60 minute of treadmill exercise at 60% of maximum oxygen uptake (exercise). On day 2, participants will rest and consume two high fat meals (breakfast and lunch) over an 8-h period during which 13 venous blood samples and nine blood pressure measurements will be taken at pre-determined intervals. It is hypothesised that men who smoke cigarettes will exhibit impaired fasting and postprandial metabolic risk markers compared to non-smokers, but a single bout of exercise will be equally, if not more, efficacious for improving the CHD risk factor profile in smokers than non-smokers.

NCT ID: NCT03732066 Recruiting - Coronary Disease Clinical Trials

Web basEd soCial Media tecHnology to Improvement in Adherence to Dual anTiplatelet Therapy Following Drug-Eluting Stent Implantation

WeChat
Start date: December 1, 2018
Phase: N/A
Study type: Interventional

Few studies have attempt to improve DAPT adherence through social media. The investigators will explore the prevalence of DAPT discontinuation and prove the hypothesis that using social media will improve DAPT adherence among patients requiring DAPT following DES implantation.

NCT ID: NCT03731936 Recruiting - Clinical trials for Coronary Artery Disease

Artificial Intelligence to Assess the Association Between Facial Characteristics and Coronary Artery Diseases

Start date: July 10, 2017
Phase:
Study type: Observational

The purposes of this study are 1) to explore the association between facial characteristics and the increased risk of coronary artery diseases; 2) to evaluate the diagnostic efficacy of appearance factors for coronary artery diseases.

NCT ID: NCT03730116 Not yet recruiting - Clinical trials for Arterial Hypertension

Assessment of the Efficacy and Tolerability of the Fixed-dose Combination of Bisoprolol/Perindopril in Patients With Arterial Hypertension and Stable CAD in Daily Clinical Practice

STYLE
Start date: November 10, 2018
Phase:
Study type: Observational

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.

NCT ID: NCT03729739 Not yet recruiting - Clinical trials for Coronary Artery Disease

Functional Assessment by Virtual Online Reconstruction. The FAVOR III Europe Japan Study

FAVOR III EJ
Start date: November 2, 2018
Phase: N/A
Study type: Interventional

Quantitative Flow Ratio (QFR) is a novel method for evaluating the functional significance of coronary stenosis. QFR is estimated based on two angiographic projections. Studies have shown a good correlation with the present wire-based standard approach Fractional Flow Reserve (FFR) for assessment of intermediate coronary stenosis. The purpose of the FAVOR III Europe Japan study is to investigate if a QFR-based diagnostic strategy will results in non-inferior clinical outcome after 12 months compared to a standard pressure-wire guided strategy in evaluation of patients with chest pain (stable angina pectoris) and intermediate coronary stenosis.

NCT ID: NCT03729531 Recruiting - Clinical trials for Coronary Artery Disease

Clinical Effect of No-touch Harvesting Technique in OPCABG

Start date: January 1, 2018
Phase: N/A
Study type: Interventional

This study aims to investigate the clinical effect of the new saphenous vein harvesting technique "No-touch" in off-pump coronary artery bypass grafting(OPCABG), comparing to the conventional technique. Adopting CTA to evaluate the 3 months patency of the graft, we will compare veins harvested using No-touch technique to saphenous veins using conventional open technique.
