Filter by:Aim and background: This study will seek to identify physiological and biochemical factors explaining and predicting a higher than expected central (aortic) blood pressure (BP) in patients with chronic kidney disease (CKD). The basic hypothesis of the study is that the degree of aortic calcification is an important component of elevated central BP, which, in turn, is important for the organ-damage and increased risk of cardiovascular disease associated with CKD. Methods: Adult patients with varying degrees of CKD undergoing scheduled coronary angiography (CAG) at Aarhus University Hospital will be included in this study. During the CAG procedure, systolic and diastolic BP is determined in the ascending part of aorta by a calibrated pressure transducer connected to the fluid-filled CAG catheter. Simultaneous with the registration of invasive aortic BP, estimation of central BP is performed using radial artery tonometry (SphygmoCor®), while a corresponding brachial BP is also measured. Prior to the CAG, a non-contrast CT scan of aorta in its entirety will be performed to enable blinded quantification of calcification in the wall of aorta and coronary arteries. Furthermore, echocardiography, resting BP measurement and a range of blood- and urine samples will be performed.
Patients (pts) with stable coronary artery disease (CAD) requiring coronary artery bypass graft surgery (CABG) may be physically inactive during the waiting period to avoid further risks. Aim of this study is to investigate the feasibility and safety of a preoperative aerobic exercise training in these pts during the waiting period and to analyze its effects on pre-, peri and postoperative outcomes
correlation between EFT volume measured by Cardiac MRI and the angiographic severity of coronary artery disease (Syntax Score) in diabetic vs non diabetic CAD population and detect if there is a cut off value for each group that could predict higher risk.
Since Gruntzig successfully performed percutaneous coronary balloon angioplasty in 1977, percutaneous coronary intervention has developed rapidly. From bare metal stents to drug-eluting stents (DES), the symptoms and prognosis of patients with coronary heart disease (CHD) have been greatly improved. Although DES has reduced the probability of in-stent restenosis (ISR) and thrombosis compared with BMS since its clinical application, it can not completely solve this problem. Even if the new generation of DES requires revascularization, the incidence of ISR is still as high as 5%-10%. DES treatment is associated with delayed endothelial healing, late acquired poor stent adherence and new atherosclerosis, which lead to late ISR and thrombosis. In addition, DES is still not ideal for the treatment of small vessel disease, diffuse long lesion and bifurcation lesion. Therefore, drug coated balloon (DCB) has attracted people's attention. Balloon-loaded antiproliferative drugs can fully release the drugs to the vascular wall during balloon dilation, which can inhibit the restenosis process from the beginning of injury, and show good efficacy and safety in some specific lesions. Many clinical studies have shown that DCB has good efficacy and safety in some specific lesions (ISR, small vessel disease, bifurcation disease, in situ lesion). Especially in the treatment of ISR, researchers believe that its efficacy is not inferior to DES, and it has the advantage of non-metal residues. Quantitative flow ratio (QFR) is the second generation FFR detection method based on angiographic images. The diagnostic accuracy of QFR 0.80 for myocardial ischemic stenosis was 92.7%. Compared with QCA, the positive predictive value and negative predictive value of QFR were also significantly better than those of QCA. The latest FAVOR II results also confirm that QFR is more sensitive and specific in diagnosing myocardial ischemia caused by coronary artery stenosis than QCA, and confirm the feasibility of using QFR online in catheter lab to evaluate the functional significance of coronary artery critical lesions. However, there is no report on the treatment of de novo lesions in patients with coronary heart disease by DCB under the guidance of QFR. The aim of this study was to evaluate the safety and efficacy of drug balloon therapy for de novo lesions in patients with CHD under the guidance of QFR compared with DES implantation.
1. The primary technical endpoint was the diagnostic performance of the QFR against the FFR. 2. The primary clinical endpoint was target vessel failure (TVF) between two groups distributed by a QFR cut-off value of 0.8
Background: Although patients' education programs improve health-related knowledge that promote individual capacity to understand basic health information, there is a scarcity in the studies that address cardiac educational programs for patients with coronary artery diseases in Jordan and their impact on patients` health outcomes. Aim: the aims of this study are to assess the level of knowledge and satisfaction of patients with coronary artery disease and to evaluate the effect of implementing a cardiac educational program on patient's level of knowledge and satisfaction. Methods: This study will be carried out using a true experimental two groups pre and post- test. The necessary information will be collected from 138 patients with CAD in the north of Jordan using the Coronary Artery Disease Education Questionnaire (CADE-Q) and the Patient Satisfaction Scale (PSS). The expected outcomes include establishing foundational knowledge about the effectiveness of cardiac educational program on patient health related out comes. Evidence on the effect of cardiac educational program will help patients to recover from a heart attacks, prevent future heart problems, hospital stays and death related to heart problems as well as making a necessary life style changes. Keywords: coronary artery disease, educational program, patient satisfaction, patient knowledge.
The retrospective study will investigate the clinical performance and long-term safety of scaffold implantation in a real world setting including high volume PCI centers in Italy
This study aims to gather information to what extent patients follow the treatment regimen of low-dose aspirin for primary and secondary prevention of diseases of the heart and blood vessels. Researcher will collect information about the percentage of time a patient has access to the medication, how long patients continue with the medication and of the proportion of patients who switch from dual-antiplatelet therapy (including low-dose aspirin) to a single antiplatelet therapy. The study will make use of secondary healthcare data sources converted in to Observational Medical Outcomes Partnership (OMOP) common data model within the Observational Health Data Sciences and Informatics (OHDSI) network.
The aim of this research is to know the incidence of arrhythmias in on vs. off pump CABG and to know their relations to the patient's morbidity and mortality, hospital stay and hospital costs.
Our objective is to find an effective prophylactic intervention by evaluating IV acetaminophen's impact in reducing the frequency of postoperative delirium, one of the most common and detrimental complications of cardiac surgery in older adults.
