NCT ID: NCT03180060 Completed - Coronary Disease Clinical Trials

Meta-Analysis of Stress Myocardial Perfusion Imaging

Start date: August 3, 2015
Phase: N/A
Study type: Observational

Background: Detection of coronary artery disease (CAD) is important due to its high prevalence and its medical and economic implications. Purpose: A systematic review of the diagnostic performance of stress echocardiography (Echo), SPECT, cardiac magnetic resonance (CMR), CT Perfusion (CTP) and PET versus invasive coronary angiography (ICA) or fractional flow reserve (FFR) using hierarchical summary ROC (HSROC) methods. Data Sources: MEDLINE, EMBASE and SCOPUS for literature published in English or Spanish from January 1970 to December 2015. Study Selection: For inclusion, studies had to meet the Cochrane guidelines, had to evaluate the sensitivity and specificity methods, and use ICA and/or FFR. Only those studies with STARD methodology ≥60% were included. Data Extraction: Ten investigators extracted patient and study characteristics and 4 resolved any disagreements.

NCT ID: NCT03179592 Recruiting - Clinical trials for Coronary Artery Disease

VOLtage-based Contrast Media AdaptatioN in Coronary Computed Tomography Angiography

Start date: March 22, 2017
Phase: Phase 3
Study type: Interventional

The purpose of this study is to prospectively evaluate the effectiveness of low-volume contrast media (CM) injection protocols adapted to tube voltage in patients undergoing Coronary Computed Tomography Angiography (CCTA).

NCT ID: NCT03179137 Recruiting - Clinical trials for Coronary Artery Disease

Mitochondrial Bioenergetics and Role in Cellular Damage in Ischemic Myocardium

Start date: October 1, 2016
Phase: N/A
Study type: Observational

Cardiac ischemia is a common pathological condition, known to elicit multiple pathological processes at the cellular level. One of the most affected is thought to be cellular metabolism, key for the adequate cardiac function. The aim is to study mitochondrial bioenergetic function, interaction with other cellular systems and influence of several co-morbidities in myocardium of the affected patients.

NCT ID: NCT03178591 Recruiting - Clinical trials for Diabetes Mellitus, Type 2

Effects of DPP4 Inhibitor Versus SGLT2 Inhibitor

Start date: October 2014
Phase: Phase 4
Study type: Interventional

Type 2 diabetes mellitus (type 2 DM) is an important disease with increasing prevalence worldwide. More than 60% of diabetes patients die of CVD. Diabetes is associated with 2-to 4- fold increase in the risk of coronary artery disease (CAD). Diabetes patients with stable ischemic heart disease may have more prevalent of asymptomatic ischemia or silent ischemia due to autonomic neuropathy. Therefore, detection of total myocardial ischemia including both symptomatic and silent ischemia using ambulatory electrocardiogram monitoring may provide better accuracy in ischemic burden and prognosis in diabetes patients. DDP-4 inhibitors have favorable effects on atherosclerotic risk factors beyond glycemic control. Furthermore, DPP-4 inhibitors may have favorable effects on ischemic preconditioning in patients with CAD. For this study we aim to compare the effects of between vildagliptin and Dapagliflozin on ischemic burden defined by total ischemic time, markers of autonomic function, biomarkers of myocardial injury and biomarkers of inflammation.

NCT ID: NCT03177486 Completed - Clinical trials for Coronary Artery Disease

Frank Score and Coronary Artery Disease

Start date: December 1, 2015
Phase: N/A
Study type: Observational

Patients with coronary artery disease (CAD) were enrolled. CAD was diagnosed by coronary angiography which also resulted Syntax score. Images of left and right ears were captured by a digital camera. Frank score of each patients was calculated based on characteristics and numbers of wrinkles of the earlobes. Statistic analysis were carried out to analyze the correlation between Frank Score and Syntax Score.

NCT ID: NCT03176810 Active, not recruiting - Coronary Disease Clinical Trials

Comparison Between Optimal Coherence Tomography Guidance and Angiography Guidance in Percutaneous Coronary Intervention

Start date: April 1, 2017
Phase: N/A
Study type: Interventional

The present study aims to demonstrate the superiority of optical coherence tomography (OCT)-guided percutaneous coronary intervention (PCI) compared with Angiography-guided PCI.

NCT ID: NCT03175393 Recruiting - Clinical trials for Postprandial Dyslipidemia

Relation Between Postprandial Lipogram and Coronary Artery Disease Severity

Start date: July 1, 2017
Phase: N/A
Study type: Observational

Coronary artery disease (CAD) is usually used to refer to the pathological problem affecting the coronary arteries (usually atherosclerosis) that leads to Coronary Heart disease (CHD) which includes the diagnoses of angina pectoris, MI and silent myocardial ischemia. Despite the mortality for this condition has gradually declined over the last decades in western countries, it still causes about one-third of all deaths in people older than 35 years. Dyslipidemia is very important risk factors of atherosclerosis that is one of the causes leading to cardiovascular disease Despite management of dyslipidemia by controling fasting total plasma cholesterol and LDL cholesterol as these are the best biomarkers for prediction of cardiovascular diseases (CVD) risk. LDL elevation is absent in many patients with atherosclerosis and about 1/3 of cardiac events remains to be unpredicted using this method. Even more, in fasting normolipidemic subjects, increased CVD risk is associated with an exaggerated postprandial lipemic response. Postprandial dyslipidemia is defined as a rise in triglyceride-rich lipoproteins (TRLs), including chylomicron remnants (CMRs) and remnant lipoproteins (RLPs), after eating, has drawn an increasing interest recently because of its association with cardiovascular events. Chylomicron remnants (CMRs) have been shown to penetrate the artery wall and to be retained within the intima. Endothelial dysfunction is an initial process of atherogenesis and it contributes to the pathogenesis of CHD. Postprandial hyperlipidemia (postprandial hypertriglyceridemia) is involved in the production of proinflammatory cytokines, recruitment of neutrophils, and generation of oxidative stress, resulting in endothelial dysfunction

NCT ID: NCT03174418 Not yet recruiting - Clinical trials for Atherosclerosis, Coronary

Fluid-dynamics in Bifurcation PCI

Start date: September 2017
Phase: N/A
Study type: Observational

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.
