Active clinical trials for "Coronary Artery Disease"

This study aims to evaluate the psychometric properties of a newly developed FFQ specified for northern Chinese CHD and their high risk patients (CHD-FFQ). The psychometric properties include test-retest reliability, content validity, convergent validity, discriminant validity, concurrent validity and predictive validity. Particularly, this study will measure the physiological indicators, including plasma lipid profile (i.e. TG, TC, HDL-C, LDL-C), BG, BP and BMI twice at baseline and the end. The level of these physiological indicators will be compared with the fat intake measured by the CHD-FFQ, i.e. the baseline intake to test its convergent validity. It is also expected to predict the diet-related progression of CHD risks among high-risk individuals, i.e. patients with two or more CHD risk factors as following: raised fasting blood glucose (BG) level, increased blood pressure (BP), increased triglycerides (TG), decreased HDL-Cholesterol (HDL-C), increased LDL-Cholesterol (LDL-C), smoking and central obesity (International Diabetes Federation, 2015). In addition, this study will provide the FFQ's concurrent validity in assessing the intake of energy and nutrients against the CDC-FFQ. Moreover, whether the FFQ could detect the known differences in energy intake between men and women will be established for its discriminant validity.

The investigators sought to investigate the prognostic implication of qualitative and quantitative plaque analysis on coronary CT angiography (CCTA) according to fractional flow reserve (FFR). The main objective was to develop a comprehensive risk model by using clinical risk factors, FFR and CCTA parameters.

Left main (LM) coronary artery disease is associated with high morbidity and mortality owing to the large myocardial territory at risk for ischemia. Evidence from randomized controlled trials supports that percutaneous coronary intervention (PCI) with drug-eluting stents (DES) for LM disease is an acceptable treatment strategy compared with coronary artery bypass graft surgery in patients with low or intermediate anatomic complexity. However in-stent restenosis (ISR) after DES in LM disease is still occurring with an incidence of 9,7%. Studies comparing the percutaneous coronary intervention with coronary artery bypass grafting (CABG) in the treatment of in-stent restenosis in unprotected left main have been scarce. While surgical revascularization is considered to be the standard treatment for this kind of stent failure, owing to a high risk of perioperative morbidity and mortality, the restoration of flow with PCI may be a reliable alternative. Additionally, it is not clear whether re-PCI is safe in these patients. Therefore, the purpose of the present study was to compare long-term outcomes following PCI or CABG for UPLM-ISR disease.

A retrospective analysis of all patients that underwent carotid endarterectomy (CEA) for stenotic disease - diagnosed at pre-operative investigation - prior to CABG as staged operation within 6- months. The rate of postoperative stroke and complications was compared between CEA performed under Local anaesthetic (LA) to those performed under General anaesthetic (GA).

A prospective analytic study to evaluate the incidence, clinical and laboratory characteristics, extent of coronary artery disease and short-term outcome of newly diagnosed diabetes and pre-diabetes in patients with first-time diagnosed coronary artery disease treated in Saud Al Babtain Cardiac Center.

The development of coronary artery disease is multifactorial. Peripheral blood biomarkers paly an important role in the prediction of coronary artery disease. However, the identification of those biomarkers and their correlation with the presence and severity of coronary artery disease are unclear. The present study aims to identify the differentially expressed biomarkers from peripheral blood between normal population and patients with different disease burden confirmed by coronary angiography, and to analyze the correlation of those biomarkers with the severity of coronary artery disease. Finally, the prediction of biomarkers for clinical events.

This trial is designed to associate angiography-based fractional flow reserve (3D-angio-based FFR) values with optical coherence tomography findings in pre- and post-percutaneous coronary intervention in patients with non-ST segment elevation acute coronary syndromes.

The aim of this study is to compare coronary artery dimensions on Cardiac CT angiography amongst different ethnicities in Trinidad.

A multi-center, prospective, observational, non-interventional single arm, study of the intermediate-term clinical outcomes collected from electronic health records of high-risk patients which have previously undergone standard of care prophylactic Impella support for a non-emergent percutaneous coronary intervention (PCI).

The FLORIDA (Fractional FLOw Reserve In cardiovascular DiseAses) study sought to investigate outcomes of FFR-guided versus angiography-guided treatment strategies in a large, real-world cohort.
