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

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

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

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: NCT03729401 Not yet recruiting - Clinical trials for Coronary Artery Disease

Personalization of Long-Term Antiplatelet Therapy

Start date: November 2018
Phase: Phase 4
Study type: Interventional

In patients after myocardial infarction (MI) (heart attacks) and treated with percutaneous coronary intervention (PCI), the current standard is dual antiplatelet therapy (DAPT), with aspirin and a P2Y12 receptor inhibitor, for 1 year of treatment. At 1 year, there are several options including: i) Ongoing DAPT (with aspirin and ticagrelor), ii) Selective treatment use of a P2Y12 inhibitor based on risk profiles. This study is a pilot vanguard study to evaluate several strategies for choosing anti-platelet regimen among patients post MI and PCI at 1 year.

NCT ID: NCT03728127 Not yet recruiting - Clinical trials for Coronary Artery Disease

Brazilian Cardioprotective Diet and Nuts in Post-acute Myocardial Infarction

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

Coronary artery disease (CAD) is the leading cause of death worldwide. Dietary patterns and functional foods may play an important role in the management of cardiovascular risk factors such as overweight and dyslipidemia, as well as inflammation and oxidative stress. However, little is known regarding the effect of diets or specific nutrients on these parameters in individuals with acute myocardial infarction (AMI). The Brazilian Cardioprotective Diet (DicaBr) is based on Brazilian nutritional guidelines and also in a unique and ludic nutritional strategy. In a pilot study, this diet was effective in reducing blood pressure (intragroup comparison) and body weight (intergroup comparison) in individuals with established cardiovascular disease (CVD). However, the effectiveness of this dietary pattern supplemented with different kind of nuts is unknown. The aim of this study is to evaluate the effect of the DicaBr supplemented or not with 30g/day of different nuts on cardiometabolic parameters in patients with recent AMI. In this parallel randomized controlled trial, 600 patients ≥40 years with a recent diagnosis of AMI (60 to 180 days) will be allocated to one of two study groups: 1) DicaBr group (DCB, control group); or 2) DicaBr group supplemented with nuts (DCBN, intervention group). All patients will receive the same dietary prescription, the DCBN group also will receive 30g/day of nuts, according to the different regions of the country (South region: peanuts; Central-West and Northeast regions: cashew nut and Brazilian nut). The primary outcome will be LDL-cholesterol (LDL-c) levels after 16 weeks. In the baseline and at the end of the study (16 weeks), lipid and glycemic profile and anthropometric indexes will be evaluated in both groups; inflammatory and oxidative stress markers, and adipokines will be evaluated in a subsample. It is expected that DicaBr supplemented with nuts will be superior to DicaBr alone to benefit patients with AMI regarding cardiometabolic parameters.

NCT ID: NCT03718429 Not yet recruiting - Clinical trials for Coronary Artery Disease

Pharmacodynamic Effects of Low-dose Rivaroxaban With Antiplatelet Therapies

Start date: December 2018
Phase: Phase 4
Study type: Interventional

Recent studies indicate that anti-factor-Xa inhibition with low-dose rivaroxaban may have a role in the reduction of ischemic recurrences in patients with atherosclerotic disease manifestations. To date there is very little data, and not conducted in human subjects, on the interplay between anti-Xa blockade with low-dose rivaroxaban and antiplatelet therapies, and in particular how this affects profiles of platelet reactivity and thrombin generation. Given the potential role for the use of low-dose rivaroxaban for the prevention of ischemic recurrences in patients with atherothrombotic disease manifestations, including coronary artery disease (CAD) and peripheral arterial disease (PAD), the study team proposes a prospective pharmacodynamic (PD) investigation assessing the impact of low-dose rivaroxaban when used in combination with antiplatelet treatment regimens commonly used in clinical practice.
