Filter by:The goal of this prospective cohort study is to investigate cardiac comorbidity in a random sample of approximately 1200 patients from a population of outpatients with rheumatoid arthritis and axial spondyloarthritis referred to collectively as inflammatory arthritis (IA). The main questions it aims to answer are: - Using conventional echocardiography, the investigators aim to determine the prevalence of overt and asymptomatic cardiac dysfunction in a large random sample of outpatients with IA. Cardiac dysfunction will be evaluated by echocardiography and cardiac biomarkers (NT-pro-BNP, hs-TNT and hs-CRP). - In patients without known heart disease: Using 2, 5 and 10 year follow-up, the investigators aim to examine if advanced echocardiography can be used to detect early signs of heart disease by investigating the clinical significance of adding deformation measures - alone and in combination with selected biomarkers - to conventional risk factors in the cardiac risk assessment of patients with IA Participants will undergo an echocardiographic examination in combination with a general health assessment including obtainment of cardiac biomarkers and a electrocardiogram. Using advanced echocardiography - Tissue Doppler Imaging, 2- dimensional speckle tracking echocardiography, 3D-echocardiography and 3-dimensional speckle tracking echocardiography - the investigators also aim to compare myocardial deformation parameters of patients with IA to a gender and age matched control group without IA from the Copenhagen City Heart Study.
This is an retrospective extended study of a randomized clinical trial (The HOST-EXAM trial ClinicalTrials.gov Identifier: NCT02044250). Investigators will perform a retrospective analysis of all participants enrolled in this trial will be performed, until the longest follow-up duration.
The Super Rehab: Can we Achieve Coronary Artery Disease Regression? (a feasibility study) proposes to test the use of a novel lifestyle intervention (Super Rehab), in addition to standard care, for patients with both coronary artery disease and metabolic syndrome. This is a feasibility study that will test study processes, enable optimisation of the intervention and provide data for power calculations to enable design of pivotal trials of the clinical effectiveness of Super Rehab.
The purpose of this study is to evaluate respiratory parameters and functional capacity in coronary artery patients.
Surgical coronary bypass surgery (CABG) has been demonstrated to confer significant survival benefit over medical therapies patients with LMCA in earlier clinical trials1,2,3 and therefore was the revascularization modality of choice for a long time. Recently, several randomized controlled trials and meta-analyses have shown percutaneous coronary intervention (PCI) to be non-inferior to CABG in the treatment of LMCA disease4,5,6,7,8. PCI is now considered to be an appropriate alternative to CABG for LMCA disease in patients with suitable anatomy9,10. Over recent decades, LMCA PCI has been performed in patients with increasing anatomical complexity and higher risk profiles (e.g. elderly, heart failure, renal failure etc). 11,12. In recent years, remarkable advancement in interventional techniques and technologies such as 2nd/3rd generation DES and potent antiplatelet therapy have contributed to the improvement of PCI success rates and reduction in complications and adverse events. Knowledge related to long term temporal variation of clinical and procedural characteristics and outcomes in patients with LMCA disease treated with PCI will therefore be important to inform and define future treatment strategies. This proposal aims to evaluate time-trends and regional differences in clinical characteristics and outcomes of patients with LMCA disease treated with PCI in the Asia-Pacific region
ECG is one of the classic tests for coronary artery disease, but patients with coronary artery disease often have no onset of typical symptoms at the time of consultation, so it is difficult to capture ischemic changes on a conventional ECG. In this study, a diagnostic test was performed to assess the diagnostic value of wearable ECG for coronary artery disease, with the gold standard of coronary angiography and quantitative flow fraction. In addition, we followed up with the enrolled participants for 1 year to assess the relationship between wearable ECG and long-term prognosis.
Background: Despite improvements in surgical and anesthesia procedures over the past 15 years complications during cardiac surgery still remain high. Bridgewater B et al. describes mortality during on-pump coronary artery bypass grafting (CABG) at 2%-3%, and the rate postoperative complications about 20%-30%. At the same time, the standard of care in patients undergoingon-pump CABG is not fully established. Hypothesis, Research Need: Use of multimodal low-dose opioid anesthesia during CABG decreases inflammatory response and the incidence of early postoperative cardiac complications due to a reduction in interleukin-6. Methodology: According to anesthesia standard protocol, all patients were divided into two groups - study group with multimodal low-dose opioid anesthesia (60 patients) and control group with a high-dose opioid anesthesia (60 patients). Primary (IL-6 at the end of the operation) and secondary clinical outcomes (postoperative atrial fibrillation (POAF), low cardiac output syndrome (LCOS), duration of mechanical ventilation (MV), length of intensive care unit (ICU) stay, length of hospital stay) were compared between the groups. Analysis Tools: Clinical observations; instrumental research methods (electrocapdiography, echocardiography); labs (blood gases, hemoglobin, electrolytes); enzyme-linked immunosorbent assay (IL-6); statistical (Student's t-test, Mann-Whitney U test, χ2-test, correlation analysis). Expected Outcomes: Use of multimodal low-dose opioid anesthesia during CABG will decrease inflammatory response (lower levels of IL-6 at the end of the surgery) and the incidence of early postoperative cardiac complications, expressed as lower incidence of LCOS and POAF, lower duration of MV and lower length of ICU stay.
The aim of the DYNAMITE study is to investigate the (a) acute procedural and (b) 9-month follow-up performance of DynamX Drug-Eluting Coronary Bioadaptor System implantation in complex coronary lesions.
The purpose of this study to determine the prognostic value of the Selvester QRS score for perioperative myocardial injury following elective non-cardiac surgery.
