Preoperative Use of Fractional Flow Reserve in CABG Use and Effectiveness of FFR-based CABG in Real-life Practice

Start date: May 2020
Phase:
Study type: Observational

The use of fractional flow reserve (FFR) to guide coronary artery bypass graft (CABG) is controversial and not ubiquitously adopted across the units. There is no definitive evidence that the use of FFR improves early clinical outcomes after CABG, with the exception of a simplification of the procedure. FFR use may help in defining the indication to the use arterial grafts, but there is no evidence that preoperative FFR lead to any benefits in terms of patency when venous grafts are used. On these grounds a large multicentric all-comers observational study is planned. The aim is to achieve a real-life picture of the FFR practice in CABG across several European and non-European units. This study will inform on the effective use rate of FFR in the CABG practice and its clinical effectiveness when compared to standard angiography-based CABG.

NCT ID: NCT04361552 Withdrawn - Clinical trials for Coronary Artery Disease

Tocilizumab for the Treatment of Cytokine Release Syndrome in Patients With COVID-19 (SARS-CoV-2 Infection)

Start date: April 7, 2020
Phase: Phase 3
Study type: Interventional

This phase III trial compares the effect of adding tocilizumab to standard of care versus standard of care alone in treating cytokine release syndrome (CRS) in patients with SARS-CoV-2 infection. CRS is a potentially serious disorder caused by the release of an excessive amount of substance that is made by cells of the immune system (cytokines) as a response to viral infection. Tocilizumab is used to decrease the body's immune response. Adding tocilizumab to standard of care may work better in treating CRS in patients with SARS-CoV-2 infection compared to standard of care alone.

NCT ID: NCT04176978 Withdrawn - Atherosclerosis Clinical Trials

PsA T2T Statin Trial on Carotid and Coronary Atherosclerosis

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

Psoriatic arthritis (PsA) is a chronic inflammatory disease associated with an increased risk of myocardial infarction (MI). Using coronary computer tomography angiogram (CCTA), it is found that a significantly higher prevalence of high-risk coronary plaque (non-calcified plaque [NCP]), supporting the notion that more aggressive cardiovascular (CV) evaluation strategy should be considered in these patients. Carotid ultrasound screening in this population may be a better alternative than traditional risk score to identify patients at high CV risk as the latter underestimated CV risk. Previous study from our group have demonstrated that achieving treatment target (minimal disease activity [MDA]) can prevent progression of carotid atherosclerosis. Nevertheless, 38% of this Treat to Target (T2T) cohort still had carotid plaque progression. Project description it is hypothesized that combination of a T2T stratgy together with high-intensity rosuvastatin treatment (Group 1: T2T-statin group) is more effective in preventing progression of coronary and carotid atherosclerosis than T2T stratgy alone (Group 2: T2T-only group) in high-risk PsA patients with carotid plaque. The primary outcome is to ascertain the effect of T2T strategy with high-intensity rosuvastain (Group 1: T2T-statin group) on the change in CIMT over a period of 12 months compared with T2T strategy alone (Group 2: T2T-only group)

Cardiac Risk Assessment Using Standard of Care Versus CTA and Heart Flow FFRct

CRASCH-Liver
Start date: June 2023
Phase: N/A
Study type: Interventional

Coronary Artery Disease (CAD) is the narrowing or blockage of the artery of the heart and is prevalent in end-stage liver disease. Consultation with cardiologist and stress tests are recommended to patients under consideration for liver transplant. The purpose of this study is to evaluate if Computed Tomography Angiogram (CTA) and CTA-derived Fractional Flow Reserve (FFRct) procedure influences decisions about further cardiac testing compared with Standard of Care (SOC) such as consultation by a cardiologist, Echocardiogram (ultrasound of the heart), Electrocardiogram (ECG) and stress tests.

NCT ID: NCT04043091 Withdrawn - Clinical trials for Coronary Artery Disease

Coronary Angiography in Critically Ill Patients With Type II Myocardial Infarction

Start date: September 2019
Phase: N/A
Study type: Interventional

Study type: prospective cohort and randomized trial. Duration: estimated 2 years. Indications: Type II myocardial infarction in critically ill patients. Purpose: 1. To recognise the incidence of type I myocardial infarction (MI) in patients with suspected type II MI. 2. Determining the safety of early coronary angiography in this population. 3. Assessment of the effect of percutaneous coronary revascularization in critically ill patients with stable obstructive coronary disease and type II MI. Hypotheses: 1. Obstructive coronary artery disease suitable for percutaneous revascularization is present in majority of patients with type II MI. 2. Type I MI (acute coronary artery thrombosis) is present in some patients and not recognised. 3. Echocardiogram and a 12-lead electrocardiogram are not reliable in predicting coronary artery disease. 4. Urgent invasive diagnostic is safe in patients with type II MI. 5. Percutaneous revascularization (if indicated) reduces the size of myocardial necrosis in patients with type II MI. Objectives: - Primary endpoint: to demonstrate that percutaneous coronary intervention (PCI) in the group with obstructive coronary disease reduces the size of MI. - Secondary endpoints: improved cardiac function after revascularization, shorter hospitalization, reduced mortality. - Safety objective: renal function, bleeding complications. Population: 140 patients with type II MI over 18 years of age with no evidence of active bleeding. Inclusion criteria: - age> 18 years - High sensitive troponin I > 40 ng / L for women and > 58ng / L for men - Critical illness (at least one vital organ support) - Imaging signs (electrocardiogram or ultrasound) signs of myocardial ischemia Exclusion criteria: - active bleeding - terminal illness Monitoring of patients: during hospitalization, 30 days after discharge, 6 months after discharge. Performance check: - PCI success (% of "thrombolysis in myocardial infarction" flow 3) - the size of MI (troponin area under the curve) - left ventricular ejection fraction - hospital stay - 30 day survival Safety Check: - monitoring of renal function - monitoring of bleeding complications - monitoring of allergic reactions to contrast and medication Patient Consent: written informed consent for inclusion in the study in conscious population. In unconscious patients, written consent will be obtained in the event of mental function improvement.

NCT ID: NCT04016363 Withdrawn - Clinical trials for Coronary Artery Disease

Impact of the ProbeFix on the Workflow of Pharmacological Stress Echocardiography Examinations

Start date: January 1, 2020
Phase: N/A
Study type: Interventional

Pharmacological stress-echocardiography examinations are routinely performed in daily clinical practice. Usually, the echo probe is manually placed on the patient's thorax by the physician. The ProbeFix is a novel device, enabling the fixation of the ultrasound probe on the patient's thorax. Therefore, there is no need to manually hold the probe. This may improve the standardization of the examination and my reduce its duration. The present trial will investigate, whether the utilization of the ProbeFix reduces the duration of stress-echocardiography examinations and improves standardization of image acquisition.

Adipose Stromal Cells Injection in the Myocardium for Induction of Revascularization

ADMIRE
Start date: December 1, 2021
Phase: Phase 3
Study type: Interventional

Treatment of ischemic myocardium has been the subject of intense research in recent years and stem cell therapy is one of the great promises. The InCor laboratory has studied cells from different backgrounds as candidates for cell therapy in the context of myocardial infarction. Evidence in preclinical studies of the application of stromal (mesenchymal) adipose tissue (hASC) in the ischemic heart by both the InCor group (in the animal model in rodents and pigs) and others in the literature suggest relevant benefits on the decrease of deterioration post-infarction. More recently it has been demonstrated that it arises mainly from the formation of new vessels due to paracrine factors, which are secreted by the injected cells. There are currently no studies in Brazil in which the safety of injecting different doses of hASC cells into the heart has been particularly evaluated. Recently, two studies have demonstrated the clinical applicability of hASC in patients with peripheral ischemic disease and stroke. Thus, the objective of this work will be to test the hypothesis that the implantation of autologous stromal cells derived from adipose tissue combined with myocardial revascularization surgery in patients with coronary artery disease
