Active clinical trials for "Cardiovascular Abnormalities"

The overall objective of the AFFECTS Study is to assess agreement between SPECT and FFRct in identifying vessel-specific, hemodynamically significant CAD in patients scheduled for invasive coronary angiography (ICA) based on abnormal SPECT myocardial perfusion scans. In particular, the study will evaluate the ability of FFRct to correctly rule out hemodynamically significant CAD in patients with non-significant CAD or normal coronary arteries who had positive SPECT scans.

Prospective, non-randomized, multicenter post-approval study to collect long term clinical and echographic data on Mitroflow DL patients.

Recent case-control studies have proven that the retinal vascularization mirrors the cardiac vascularization: more the coronary network is altered, more the density of retinal vessels is reduced. No studies have yet been realised in primary prevention. This study aims to demonstrate a link between the density of the retinal vascularization and the calcium score, which is currently the gold standard for the classification of cardiovascular risk in primary prevention. Thus, a simple image of the retinal vascularization could predict the cardiovascular risk of a patient. OCT angiography would become a major aid in the classification of cardiovascular risk in asymptomatic patients.

The primary objective is to assess the effect of 2 dose levels of SNF472 (300 mg and 600 mg) compared to placebo on the progression of coronary artery calcium volume score over a 12-month (52 weeks) period in ESRD patients on HD

This observational study aims to assess the performance of the software called ausculto™. ausculto™ is a collection of computer algorithms that intend to analyse heart sounds recorded from the built-in microphone of a smartphone for abnormal sounds. Participants will have their heart sounds recorded during their regular clinic appointment after consenting to participate in this study. Researchers will manually annotate the recorded heart sounds to create a database for use in future training and testing of artificial intelligence (AI) intended for medical uses.

The phosphatidylinositol 3-kinase (PI3Kinase)/Protein Kinase B (AKT)/mammalian target of rapamycin (mTor) pathway plays a role on the development and the lymphatic-vascular organisations. The investigators want to study the efficacy and the safety of Rapamycin, an mTor inhibitor.

The purpose of this study is to evaluate the safety and short-term effectiveness of implantation of Transcatheter Pulmonary Valve (TPV) for the treatment of congenital heart disease with pulmonary valve disease.

The purpose of this study is to look at the safety (what are the side effects) and efficacy (how well does it work) of Magnevist (the study drug) used for MRI of the aortic arch and cerebral branches. The results will be compared to the results of MRI taken without Magnevist, and with the results of your X-ray angiography.

Cardiovascular diseases (CVD), primarily heart disease and stroke, are the leading causes of death and prescription drug use in Canada. Research on certain dietary supplements looks promising as a way to help reduce CVD risk factors. Studies show that supplementation of certain nutrients such as antioxidants, amino acids, electrolytes, vitamins and minerals may effectively reduce cardiovascular risk factors. The dietary supplement CardioFlex Q10, which is high in the aforementioned components, was developed to help regulate the body's production of cholesterol, strengthen the arteries and heart, and reverse oxidation. The overall objective of this study is to determine if 90 days of supplementing with CardioFlex Q10 can reduce CVD risk factors in adults, independent of other dietary or physical activity changes.

The goal of this study is to find out if giving intravenous B-vitamins before general anesthesia with nitrous oxide prevents the increase in homocysteine, a metabolite that has been linked to cardiovascular complications.
