NCT ID: NCT04321434 Terminated - Clinical trials for Ischemic Heart Disease

Hyperoxia and Microvascular Dysfunction

Start date: December 1, 2016
Phase: N/A
Study type: Interventional

Coronary artery disease (CAD) pathophysiology involves endothelium-dependent (e.g. nitric oxide, acetylcholine) and -independent (e.g. adenosine) vascular dilation impairment, which have been demonstrated at the level of small coronary arteries, medium sized peripheral arteries and subcutaneous microcirculation. Oxygen supplementation, which is frequently overused in clinical settings, seems harmful in acute coronary syndromes and increases microvascular resistance in myocardial and subcutaneous microcirculation through alteration of endothelium-dependent and -independent dilation by an oxidative mechanism. Whether endothelial dysfunction, that is well documented at the level of cardiac microcirculation in CAD patients, is also present at the level of subcutaneous microcirculation is unknown. Also, unknown is whether an acute oxidative stress can be used to probe myocardial microcirculatory dysfunction at the level of subcutaneous microcirculation, which is an easily accessible vascular bed for an in vivo assessment of endothelial-dependent and-independent function. Alterations in cutaneous vascular signalling are evident early in the disease processes. Thus, studying subcutaneous circulation in patients with cardiovascular risk factors could provide vascular information early in CAD processes. This study will test the following 4 hypotheses: 1. Endothelial dysfunction observed at the level of microvascular cardiac arteries is readily present at the level of subcutaneous microcirculation in a given CAD patient. 2. An acute oxidative stress such as hyperoxia can be used to test myocardial microcirculatory dysfunction at the level of the more easily accessible subcutaneous microcirculation. 3. Subcutaneous microcirculation of CAD patients has a lesser vasodilatory response to acetylcholine or sodium nipride than matched healthy subjects. In addition, CAD patients are more prone to dermal vasoconstriction in response to oxygen compared to healthy subjects. 4. Taken that oxygen is still too often given in excess in most clinical settings, the aim of this study is to rule out possible pitfalls in coronary pressure and resistance determinations in CAD patients receiving unnecessary oxygen supplementation.

NCT ID: NCT03538886 Terminated - Clinical trials for Coronary Artery Disease

Nordic-Baltic Coronary Revascularization Study in Patients With Proximal Left Descending Coronary Artery (LAD) Lesion.

NOBLE-LAD
Start date: June 1, 2018
Phase: N/A
Study type: Interventional

The Nordic-Baltic Heart Team Initiative for improved long-term coronary artery revascularization outcome compares quality of life and survival after coronary bypass grafting (CABG) vs. percutaneous coronary intervention (PCI) in patients with 1-vessel disease and proximal stenosis of the anterior descending artery (LAD/in patients with isolated proximal left descending coronary artery (LAD) lesion

NCT ID: NCT03488654 Terminated - Clinical trials for Coronary Artery Disease

CMR-Lupus Comprehensive Approach by Cardiovascular Magnetic Resonance Tomography

Start date: July 2010
Phase:
Study type: Observational

In systemic lupus erythematosus (SLE), cardiac manifestations, e.g. coronary artery disease (CAD) and myocarditis are leading causes of morbidity and mortality. The prevalence of subclinical heart disease in SLE is unknown. We studied whether a comprehensive cardiovascular magnetic resonance (CMR) protocol may be useful for early diagnosis of heart disease in SLE patients without known CAD

NCT ID: NCT03484234 Terminated - Clinical trials for Coronary Artery Disease

Percutaneous Treatment of LONG Native Coronary Lesions With Drug-Eluting Stent-VII: Sirolimus-eluting (Ultimaster) vs. Everolimus-Eluting Stents (Xience)

LONG-DES VII
Start date: July 27, 2018
Phase: N/A
Study type: Interventional

This study compares angiographic and clinical outcomes in patients with long coronary lesions treated with sirolimus-eluting stent (Ultimaster stent) or everolimus-eluting stent (Xience Alpine stent). The study uses a randomized, multicenter, controlled design approach.

NCT ID: NCT03369184 Terminated - Clinical trials for Coronary Artery Disease

Elective Percutaneous Coronary Intervention With or Without Supplemental OXYgen

EPOXY-IMR
Start date: January 1, 2018
Phase: Phase 3
Study type: Interventional

Supplemental oxygen is frequently used in patients admitted to hospital due to ischemic heart disease. In the setting of suspected myocardial infarction, clinical practice guidelines advocate the use of supplementary oxygen even in patients with normal levels of peripheral oxygen saturation. The theoretical basis for this practice is that an increase in blood oxygen content may limit ischemia and final myocardial damage and subsequent infarct size. However, although some experimental laboratory data and small studies in humans have supported the use of supplemental oxygen in patients with coronary artery disease, contradicting evidence suggests possible harmful effects, mainly through mechanisms involving coronary vasoconstriction and reduction of myocardial perfusion (hyperoxemic coronary vasoconstriction). In the EPOXY-IMR trial, the investigators aim to further explore possible detrimental effects from routine use of supplemental oxygen on the coronary circulation with special focus on the small vessels referred to as the coronary microcirculation.

NCT ID: NCT03184805 Terminated - Clinical trials for Coronary Artery Disease

STOPping Versus Continuing Antiplatelet Therapy During Noncardiac Surgery and Procedures After Next Generation Drug-eluting Stent Implantation

Start date: June 23, 2017
Phase: N/A
Study type: Interventional

Most previous trials support the absolute increase in bleeding risk with perioperative administration of antiplatelet. Furthermore, recent studies demonstrated that perioperative major bleeding may be related to increase cardiovascular risk. The investigators will compare the efficacy and safety of continuing versus stopping antiplatelet therapy during perioperative period in patients underwent PCI(Percutaneous Coronary Intervention) with next generation DES(Drug Eluting Stent).

NCT ID: NCT03068286 Terminated - Depression Clinical Trials

iCBT for Long-term Conditions in IAPT

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

SilverCloud provides internet-delivered interventions for depression and anxiety in NHS Mental Health Services. The interventions have proved successful in the management of depression and anxiety for clients presenting to mental health services, with recovery rates exceeding the national standard. Recently SilverCloud has embarked on tailoring the interventions for patients with long-term conditions including COPD, pain and diabetes. The purpose of the customisation is to make the interventions more meaningful and relevant to patients with LTCs, but all the while having the same goal of addressing depression and anxiety disorders. In doing so it would be expected that individuals might be in a better position to effectively self-manage their LTC. The current study, therefore, seeks to assess the possible effectiveness of implementing customised internet-delivered interventions for depression and anxiety for people with long-term conditions presenting to NHS mental health services.
