Filter by:Patients with atherosclerotic cardiovascular disease (i.e. peripheral artery disease, ischemic heart failure, myocardial infarction) are randomised to (1) treatment as usual (i.e. best medical care) or (2) treatment as usual (i.e. best medical care) in combination with an eight-week mindfulness-based stress reduction programme.
Cardiovascular disease is a leading cause for morbidity and mortality in general population. The incidence of cardiovascular disease and their poor outcome is well documented in a broad spectrum of connective tissue diseases, especially in rheumatoid arthritis (RA). The risk of incident CVD is increased by 48% in patients with RA compared to the general population. RA is associated with 50% increase in the mortality in patients with cardiovascular disease (CVD). One reason is the more frequent cardiovascular risk factors in RA patients compared with the general population. Patients with RA have a high risk of premature cardiovascular disease (CVD). The aim of the present study is to assess whether there are non-invasive measures that might predict arteriosclerosis in RA patients.
Determining whether we could visualize uptake of the fluorescent tracer Bevacizumab-800CW, targeting VEGF-A in atherosclerotic plaques by using the new imaging technique Multispectral Optoacoustic Tomography both in- and ex vivo.
This study was to investigate the Effect of Sitagliptin, a dipeptidyl peptidase-4 inhibitor, on progression of coronary atherosclerosis in patients with type 2 diabetes.
This study will look at the effects of standardised balloon inflation times, pressure and balloon types and atherosclerotic plaque morphology on the procedural results of percutaneous coronary intervention (PCI).
Studying and investigating the association between dietary habits and risk factors for atherosclerotic cardiovascular diseases in Assiut governorate
the study will be carried out to standardize normal parameters of vascular duplex ultrasound of the cranial vessels in the Egyptian population.
A total of 210 coronary atherosclerosis patients without indications for stent implantation are included. The baseline values of platelet aggregation rate, plasmaThromboxaneB2 and urinary 11-dh ThromboxaneB2 are measured by Light Transmittance Aggregometry method and ELISA after aspirin 100 mg /d ≥5d. Then the patients are randomly divided into 7 groups: Group1: aspirin 100 mg/d; Group2: aspirin 100 mg /2d; Groups3: aspirin 100 mg / 3d; Groups4: morning 50mg evening 50mg; Group5: aspirin 75mg / d; Group6: aspirin 50mg / d; Group7: indobufen100mg bid. One month later,arachidonic acid-induced platelet aggregation rate , plasma TXB2 and urine 11-dh TXB2 are analyzed again. All patients are followed-up for 1 year. The stomach Intestinal reactions, small bleeding events are recorded.
Recently, the investigators have been screening for anti-atherogenic or pro-atherogenic amino acids (AAs) in the macrophage model system to better understand their role in atherogenesis. The findings so far suggest that specific AAs induce selective anti-atherogenic effects (glycine, alanine, leucine and cysteine) or pro-atherogenic effects (glutamate and glutamine) in macrophages. Taking together the above previous reports with the mechanisms behind macrophage foam cell formation and atherogenesis, it is possible that AAs could be anti-atherogenic or pro-atherogenic via their mechanism of action on macrophage foam cell formation. This paradigm may serve as a basis for the development of novel cardio-protective, anti-atherogenic nutritional, or therapeutic approaches, that should be studied in human trials.
Investigator-initiated, international, multicentre, observational study with two cohorts. The two study cohorts will be: Cohort A: to understand if the local blood flow patterns (associated with low WSS), as evaluated by computational fluid dynamic tools from combined angiographic and OCT invasive images, may better predict the clinical outcome of patients with bifurcated coronary lesions treated by PCI. Cohort B: to understand if the local blood flow patterns (associated with low WSS), as evaluated by computational fluid dynamic tools from combined angiographic and OCT invasive images, may better predict the clinical outcome of patients with sub-critical bifurcated lesions managed conservatively. Coronary angiography and OCT images will be combined to obtain a three-dimensional model of the diseased coronary vessels that will be used to calculate the local blood flow patterns and the time-averaged WSS at the bifurcated lesion level by using computational fluid dynamics software. Baseline (in patients both managed conservatively and treated by PCI) and post-PCI (in patients treated by PCI) images will be processed.
