Filter by:The purpose of this study is to observe whether the electroacupuncture (EA) preconditioning for five days before operation can improve the outcomes of patients with coronary heart disease undergoing geriatric non-cardiac surgery.
The main objective of the GENOCOR project (Genetic mapping for cardiac risk assessment) is the setting up of a joint public/private laboratory (GENOCOR-LAB) dedicated to the development and testing of new cost-effective technologies exploiting the growing knowledge in the genomic correlates of cardiovascular diseases (CVD) and of their evolution; the data obtained by the GENOCOR-Lab should especially orient secondary prevention and specific treatment of ischemic heart diseases (IHD).
No previous study has assessed the potential of ranolazine to interfere with levels of platelet reactivity in patients with coronary artery disease who are treated with dual antiplatelet therapy. Aim of this study is to compare the pharmacodynamic effects of maintenance doses of ranolazine versus amlodipine on platelet reactivity in patients with coronary artery disease who are treated with dual antiplatelet therapy.
Pharmacologic alternatives in statin-intolerant patients include ezetimibe and nutraceuticals (i.e. compounds derived from foods with cholesterol lowering actions). The investigators will compare the efficacy and tolerability of ezetimibe versus a nutraceutical-based protocol in statin-intolerant patients treated with percutaneous coronary intervention.
Heart disease remains the most common cause of death in the UK. Chest pain is often the first presenting symptom in patients with heart disease, and may be a warning signal prior to a heart attack or death. The diagnosis based on symptoms alone however is unreliable and further testing is almost always necessary. Rapid access chest pain clinics (RACPCs) are able to expedite the assessment of such patients. The principal investigation used is an exercise stress electrocardiogram (s-ECG). Although simple, cheap, and convenient, the s-ECG is often inaccurate; missing the diagnosis or falsely suggesting the diagnosis. This can happen in as many as 25% of patients, resulting in a delay in treatment or unnecessary further investigation. CT Angiography (CTA) is a novel non-invasive technique where the coronary arteries can be visualised by Computerised Tomography. In previous studies it shows a high degree of correlation with invasive angiography, with a high accuracy for the diagnosis of obstructive coronary artery disease. However, the technique is relatively new, and its full role is yet to be defined in the clinical setting of a chest pain clinic. The investigators do not at present have any information as to whether it is able to speed up the diagnosis, reduce the need for other tests, and therefore also costs. In this trial, the investigators aim to examine the accuracy and cost effectiveness of CTA in patients with suspected cardiac chest pain presenting to a chest pain clinic, when compared to the more established techniques like s-ECG, myocardial perfusion scanning and coronary angiography. The study will enable us to establish the optimal and most cost effective strategy for investigation of patients presenting to chest pain clinics.
This is a comparison between Hypertonic versus isotonic solution in a double blind randomized trial for off pump Coronary Artery Bypass Graft (CABG) surgery targeting the left marginal branch. Hypertonic solution should provide better tolerance for heart mobilization with less volume expansion and less drugs.
The hypothesis is that problem based learning (PBL) in patient education positively affects self-care agency of lifestyle changes after an event of coronary heart disease (CHD). The investigators therefore aim to determine whether long-term follow-up in primary health care in patient education involving PBL affects self-care behaviour in terms of patients' beliefs, self-efficacy and empowerment to make lifestyle changes. The general aim is to evaluate if PBL in patient education after CHD affects long-term self-care in relation to present lifestyle goals. Another aim of the study is to perform an economic assessment of long term effects of life style changes reached by using PBL after en event of CHD.
Clopidogrel low response is associated with a significantly higher risk for ischemic complications after percutaneous coronary intervention. Ticagrelor and prasugrel are more potent platelet inhibitory drugs and both have been shown to significantly reduce ischemic events as compared to clopidogrel. No direct comparison between ticagrelor and prasugrel in terms of their antiplatelet efficacy exists. The aim of this study is to assess the antiplatelet treatment efficacy of ticagrelor versus prasugrel over time in confirmed clopidogrel low responders undergoing percutaneous coronary intervention.
The objective of this study is to compare a standard coronary CT angiography scan protocol with conventional image reconstruction with a scan protocol using reduced tube current and a new image reconstruction algorithm. The investigators hypothesize that the image quality of the new scan protocol is not inferior, while radiation dose estimates are reduced by around 30%. Secondary endpoints of the study include quantitative image quality parameters, prevalence of non-diagnostic studies, prevalence of coronary artery plaques and plaque characteristics (calcified, non-calcified, mixed) and prevalence of follow-up examinations.
This study is designed to evaluate the feasibility and diagnostic performance of a novel rapid regadenoson stress CMR protocol for detecting of obstructive coronary artery disease.
