HCR registry
Start date: January 15, 2019
Study type: Observational

NCT ID: NCT03783351 Not yet recruiting - Clinical trials for Acute Coronary Syndrome

Genotyping GUided Antiplatelet theRapy in pAtieNts Treated With Drug Eluting stEnts (GUARANTEE)

Start date: February 2019
Phase: Phase 4
Study type: Interventional

The aim of this study is to assess the efficacy and safety of the CYP2C19 genotype guided antiplatelet treatment strategy, using clopidogrel in non-carriers of a CYP2C19*2 or *3 allele and ticagrelor in carriers of a CYP2C19*2 or *3 allele in patients treated with new generation drug eluting stents.

NCT ID: NCT03767621 Not yet recruiting - Clinical trials for Coronary Artery Disease

Concordance Between FFR and iFR for the Assessment of Intermediate Lesions in the Left Main Coronary Artery. A Prospective Validation of a Default Value for iFR

Start date: January 14, 2019
Study type: Observational [Patient Registry]

The assessment of Left Main Coronary Artery (LMCA) lesions by means of coronary angiography renders serious limitations. Studies with a limited number of patients have shown that a value of FFR (Fractional Flow Reserve) above 0.80 identify a low risk of events in case of not performing revascularization in patients with intermediate stenosis in the LMCA. Although iFR (Instant wave Free Ratio) has recently been found equivalent to FFR The demonstration of the prognostic utility of iFR in patients with LMCA intermediate lesions could have an important clinical impact and justify its systematic use for the treatment decision in these high-risk patients.

NCT ID: NCT03702764 Not yet recruiting - Atherosclerosis Clinical Trials

Coronary Plaque Geometry and Acute Coronary Syndromes

Start date: November 1, 2018
Study type: Observational

The aim of GEOMETRY study is to investigate the correlation between coronary plaque geometric modifications and lesion vulnerability in patients with suspected coronary artery disease referred for cardiac computed tomography angiography (CCTA). Furthermore the study will evaluate the impact of plaque eccentricity and morphology on the rate of major adverse cardiovascular events (MACE) for a 2 years follow-up period.

NCT ID: NCT03702608 Not yet recruiting - Coronary Stenosis Clinical Trials

BIONICS 38 mm Trial EluNIR Ridaforolimus Eluting Coronary Stent System (EluNIR) In Coronary Stenosis Trial

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

This is a prospective, multi-center, single-arm, open-label clinical trial. Clinical follow-up will be performed at 30 days. Follow-up by phone will be performed at 6 months, and 1 year after the procedure. Study Objective is to further assess the safety and efficacy of long (38 mm) Ridaforolimus Eluting Stent - EluNIR.

NCT ID: NCT03656848 Not yet recruiting - Clinical trials for Coronary Artery Disease

The FAVOR III China Study

Start date: December 20, 2018
Phase: N/A
Study type: Interventional

The overall purpose of the FAVOR III China trial is to investigate if a strategy of quantitative flow ratio (QFR)-guided percutaneous coronary intervention (PCI) yields superior clinical outcome and cost-effectiveness compared to a strategy of standard coronary angiography-guided PCI in evaluation of patients with coronary artery disease.

NCT ID: NCT03632785 Enrolling by invitation - Clinical trials for Cardiovascular Risk Factor

Laboratory Implications of Non Obstructive Atherosclerotic Plaques Identified by Multiple Detector Coronary Angiotomography

Start date: March 27, 2017
Study type: Observational

Approximately 50% of coronary events occur in previously asymptomatic patients. Thus, the early detection of the individuals at higher risk became an important research target within the current cardiology. The various clinical scores used present a predictive accuracy for ischemic events, evaluated by the ROC curve, which ranges from 0.73 to 0, 79. Therefore, the introduction of new non-invasive techniques for the detection of atherosclerosis aims to allow a more adequate classification of risk. The development of radiological techniques, fundamentally coronary angiotomography of multiple detectors (CAMD) and electron beam computed tomography-EBCT‖, demonstrated that the degree of coronary calcification correlates with endothelial lesion and individual prognosis in the long term. Notably, the calcium score has a weak correlation with the severity of coronary stenosis per se, possibly due to variations in arterial remodeling due to coronary calcification. On the other hand, the CAMD allows the detection of a small magnitude atheromatous disease, not diagnosed clinically, nor by tests provoking ischemia, or even by coronary catheterization. The clinical relevance of the small magnitude atheromatous disease diagnosed by the ACMD and its correlation with plaque vulnerability markers, mainly platelet aggregation, vascular reactivity, and inflammation are still not well determined. This is a case and control study and we will enrolled 90 patients with low and medium risk of cardiovascular event whose cases should present discrete plaques in the CAMD e controls should present none plaque in coronary stenosis

NCT ID: NCT03606330 Recruiting - Clinical trials for Acute Coronary Syndrome

Systemic, Pancoronary and Local Coronary Vulnerability

Start date: October 22, 2018
Study type: Observational

• The aim of the VIP study is to investigate the impact of vulnerability markers (inflammatory serum biomarkers for systemic vulnerability, coronary shear stress and vulnerability mapping for pancoronary vulnerability, and imaging-based plaque features for systemic vulnerability) on the rate of major adverse cardiovascular events caused by progression of the non-culprit lesion in patients with acute ST or non-ST segment elevation myocardial infarction who undergo revascularization of the culprit lesion during the acute event. Furthermore, the study will evaluate the rate of progression of non-culprit lesions towards a higher degree of vulnerability, based on coronary computed tomography angiographic assessment at 1 year after enrollment.

NCT ID: NCT03588455 Completed - Coronary Stenosis Clinical Trials

Pronostic Impact of Flow Fraction Reserve on Intermediate Stenoses

Start date: January 1, 2018
Study type: Observational

The intermediate coronary stenoses defined by a degree of stenosis from 40 to 70 % are frequent. The Flow Fraction Reserve (FFR), realized during coronarography, is an hemodynamic evaluation by the functional impact measuring the loss of load in upstream / approval of the stenosis inthe basal state and in situation of hyperemia led by adenosine. Further to the study FAME, the threshold of definition of the significant character of one Stenosis was fixed for a value of FFR = 0,80. However, the impact forecasts intermediate values badly known rest. We hypothetized that coronary stenosis associated with borderline values of FFR 0.81-0.85 were associated with a higher rate of clinical events than those with a FFR >0.85
