Filter by:Purpose. Comparison of outcomes in patients underwent CABG combined with left atrial and biatrial radiofrequency ablation of long-standing persistent atrial fibrillation. Hypothesis of the study - patients with long-standing persistent atrial fibrillation and coronary artery disease after CABG in combination with biatrial RFA have a better outcomes for the freedom of AF compared with patients undergoing left atrial RFA during CABG.
The purpose of this study is to determine whether pharmacologic lowering of low density lipoprotein cholesterol (LDL), initiated in healthy young to middle aged adults can eliminate or markedly reduce the composite endpoint of incident all cause mortality, myocardial infarction, stroke or coronary revascularization.
The Cardiovascular disease research using Linked Bespoke studies and Electronic Records (CALIBER) e-health database was the data resource for this study. CALIBER links patient records from four different data sources: Clinical Practice Research Database (CPRD), MINAP (Myocardial Ischaemia National Audit Project registry) Hospital Episodes Statistics (HES), the Office for National Statistics (ONS).
The aim of the CARDIOBASE Bern PCI registry is to collect baseline clinical and procedural data as well as to assess the clinical outcomes of all patients undergoing percutaneous coronary intervention (PCI) at Bern University Hospital. All patients undergoing PCI with or without stent implantation will be prospectively registered. Device use is according to the decision of the treating physician and independent of this registry. At hospital discharge and one year, the following outcomes will be assessed: death, cardiac death, myocardial infarction, stent thrombosis, repeat revascularisation, stent thrombosis, stroke, bleeding, renal failure and vascular complications.
There are many risk prediction models. And their estimates are different. This study aimed to investigate the differences between the estimates of Fuwai and Reynolds risk model in Chinese, and investigate the reason for the differences.
To compile acute procedural performance and clinical outcomes data for the Promus PREMIER everolimus-eluting coronary stent system in understudied/underserved patient populations including women and minorities.
The investigators are going to recruit patients who have a scheduled elective coronary angiography and going to do a dobutamin stress echography (DSE) before the coronary examination. Next to a regular 2D-DSE, the investigators will perform an 3-dimensional DSE, incl ventriculography. In the interventional part (coronary angiography), they will measure each stenosis with fractional flow-reserve (FFR)and herewith graduate its stenosis severity.
The objective of the HEART Study is to develop a multiscale model of the coronary circulation based on multimodal imaging data (angiography, echocardiography). The predictive comprehensive multi-scale model, developed during this proof-of-concept study, will be used for analyzing functional aspects of coronary artery disease. Model validation is performed against invasive measurements
Patients with an impaired blood supply of the heart routinely receive oxygen in order to improve or preserve the oxygen supply of the heart muscle in acute cardiac care. In recent studies a new innovative MRI-technique that can detect changes in oxygen supply of the heart was able to show that the administration of oxygen or fast breathing can decrease the blood supply of the arteries supplying the heart muscle with oxygen. Thus, the administration of oxygen may paradoxically impair the oxygen supply of the heart muscle. In this study the investigators want to investigate, whether the administration of exogenous oxygen via a mask alone and in combination with fast breathing leads to a decrease in oxygen supply in regions with already impaired blood supply by a narrowing of a coronary artery of the heart.
The purpose of this study is to determine effects of combination therapy with rosuvastatin and fenofibrate on atheromatous plaques and its tissue characteristics of de novo coronary lesions with intermediate stenosis in patient with coronary artery disease, compared with rosuvastatin alone therapy.
