Filter by:Is the surgical treatment of patients with coronary heart disease using the T-graft technique an adequate solution that provides a sufficient myocardial flow reserve? A magnetic resonance examination (MRI) is required.
64 channel multidetector-row Computed Tomography (CT) has been introduced for use in the diagnosis of coronary heart disease. The investigators aimed to characterize coronary artery disease in type 2 diabetes mellitus and metabolic syndrome, and in particular plaque natures depending on different status of metabolic diseases. The investigators also aimed to analyze the risk factors associated with number and severity of stenosis as well as plaque characteristics using logistic regression models.
Recent advances in technology have resulted in the development of scanners that can n image the heart arteries within 10 to 20 minutes but without the need for admission to hospital or insertion of catheters. This means that coronary heart disease may be more readily identified (or ruled out) and allow better diagnosis and treatment of patients with symptoms suggesting coronary heart disease. Here, we propose to assess the latest and most powerful scanners to see if it can accurately diagnose the extent of coronary artery disease and facilitate the planning of heart surgery.
Some myocardial infarctions (MI) occur as the first manifestation of coronary artery disease. These are termed 'unheralded' events as they have not been preceded by other forms of coronary artery disease. Unheralded MIs are important because of the high likelihood of missed opportunities for prevention. The proportion of MIs that are 'unheralded' is unknown. This study aims to quantify the proportion of MIs that occur 'unheralded' and also give an estimate of the incidence of 'unheralded' MI in the UK, compared to 'heralded' MI and those with angina of recent onset (MIs with premonitory symptoms).
The effects of race/ethnicity on platelet function and response to antiplatelet agents will be assessed using healthy participants and coronary heart disease patients from at least 5 racial/ethnic groups.
Multidetector-row Computed Tomography (CT) has been introduced for use in the diagnosis of coronary heart disease. The investigators aimed to characterize coronary artery disease in subjects with cardiovascular risk or not, and in particular plaque natures depending on different status of cardiovascular risk. Especially,the investigators will evaluate the relationships between the pericardial fat and severity of stenosis as well as plaque characteristics using logistic regression models.
The purpose of this study is to evaluate two approaches to red blood cell transfusion in anemic patients with acute coronary syndrome.
The purpose of this study is to compare the one-time application of Paclitaxel from SeQuent Please (Paclitaxel-coated Balloon Catheter) after using the Coroflex Blue (Cobalt Chromium Stent) with the slow releasing of small dose of Paclitaxel from the Coroflex Please (Paclitaxel-Eluting Stent) stent system in a non-inferiority trial.
Background: Retrospective analyses of long-term BASKET findings identified patients with large drug-eluting stents (DES) (>2.5mm Stents) as patients at risk for late cardiac death/nonfatal myocardial infarction. In view of new DES with absorbable polymers and new bare metal stents BMS) with thin struts and biocompatible polymers, BP-II will be launched to test their comparative clinical safety up to 12 years if treated with an aspirin/prasugrel combination, since prasugrel halved stent thrombosis rates compared to clopidogrel in a large ACS trial. The primary objective is to demonstrate non-inferiority of the Nobori DES stent compared to the Xience Prime DES stent on safety and e cacy in patients requiring stents >=3.0mm in diameter on the background of contemporary dual antiplatelet therapy (DAPT) with prasugrel and aspirin Set-up: Multicenter open-label randomized trial. Patient inclusion: Unselected series of patients in need of large (>3mm) stents only in native vessels irrespective of clinical indication. Patient exclusion: In-stent restenosis, Left-main disease, cardiogenic shock, planned surgery <12months, increased bleeding risk, no compliance expected, History of stroke or transient ischemic attack (TIA). Randomization: By centre using sealed envelopes 1:1:1: Nobori:Xience Prime:Prokinetik-stent.
Growth determination factor 15 (GDF-15) and high sensitive troponin-t (hsTnT) are emerging humoral markers for risk stratification in clinically stable heart failure patients and in patients with stable coronary artery disease. No data are available about the prognostic value of these peptides in relation to mortality and morbidity in patients undergoing cardiac surgery. Primary objective of the present study is to test the hypothesis, that GDF-15 is superior to a standard preoperative risk score, the additive Euroscore for the prediction of 30 day mortality and postoperative morbidity in patients scheduled for cardiac surgery. Secondary objectives are to test the predictive value of hsTNT, either alone, or in combination with GDF-15 and if GDF-15 adds additional information to NTproBNP levels and preoperative cerebral oxygen saturation (ScO2) levels.
