Filter by:The aim of the study is to investigate if lesion preparation with a ScoreFlex balloon compared to a standard non-compliant balloon improve vascular healing and minimize lumen reduction after implantation of a Magmaris bioresorbable scaffold.
Ischemia-guided revascularization is the cornerstone of contemporary management of coronary artery disease (CAD). Coronary physiological assessment is advocated in the catheter laboratory to guide percutaneous coronary intervention (PCI), and it is widely accepted that an FFR ≤ 0.80 is a good indicator for vessels to benefit from revascularization. Nevertheless, a significant proportion of PCI patients continue to experience adverse events related to both stented segment and/or residual or diffuse disease. Our group recently demonstrated the feasibility of pullback pressure gradient (PPG) derived from virtual Quantitative Flow Ratio (QFR) pullback curve, which is an index of atherosclerosis functional pattern and can be used to epitomize the pathophysiological pattern of CAD as focal or diffuse. In this regard, the current study will investigate the incremental value of PPG added to QFR haemodynamic assessment in ischemia-causing vessels received PCI in predicting adverse outcomes.
This prospective, multicenter, randomized, controlled, open-label clinical study has a target enrollment of 240 subjects. It will explore whether STEMI patients transferred to a PCI center following thrombolytic therapy and expected to have stent implantation might benefit from an alternative treatment strategy and the use of new technologies designed to improve myocardial protection throughout the medical care process.
This is a double-blind, randomized placebo-controlled trial which aims to evaluate the efficacy and safety of Wen Xin granule in patients with unstable angina pectoris.
Large population cross sectional study, was conducted between 2018-2020 by attendance of 4526 patients in shiraz, Iran. Patients were undergone selective coronary angiography from radial artery approach by an expert interventional cardiologist. 25-hydroxy vitamin D and Hs-CRP levels were measured for all patients
Background: Office blood pressure (OBP) is used for diagnosing and treating hypertension but ambulatory blood pressure measurement (ABPM) associates more accurately with patient outcome. The optimal blood pressure in patients with coronary artery disease (CAD) is still unknown. Our objective was to investigate whether physician awareness of ABP after percutaneous coronary intervention (PCI) improved BP-control. Methods: A total of 201 patients performed ABPM before and after their PCI follow-up visit. Patients were randomized to open (O) or concealed (C) ABPM results for the physician at the follow-up visit. The change in ABP and antihypertensive medication in relation to baseline ABP was compared between the two groups.
Study for developing techniques to evaluate coronary artery hemodynamic profiles by conventional angiography without more dedicated measuring devices.
Chronic conditions such as knee or hip osteoarthritis (OA), chronic obstructive pulmonary disease (COPD), heart failure (HF), coronary heart disease (CHD), hypertension, type 2 diabetes mellitus (T2DM) and depression are among the leading causes of global disability and affect hundreds of millions of people around the world. In recent years, multimorbidity, commonly defined as the co-occurrence of at least two chronic conditions, has also gained interest due to its substantial impact on the person and society. Despite the significant burden of multimorbidity, little is known about how to treat this effectively. A 2016 Cochrane systematic review found that interventions targeting populations with specific combinations of conditions and addressing specific problems such as functional difficulties may be more effective. Exercise therapy is a treatment addressing functional limitations that is a safe and effective treatment of at least 26 chronic conditions, including OA, HF, CHD, hypertension, T2DM, COPD and depression. Furthermore, self-management support is increasingly recognized as an essential component of interventions to improve outcomes in patients living with multimorbidity and to support the long-term adherence to exercise. A new systematic review found that exercise seems effective in people with multimorbidity (the conditions included in the current study), however highlighting the need for further high-quality RCTs. The aim of this randomized controlled trial (RCT) is to investigate the effects of a personalized exercise therapy and self-management support program in addition to usual care on self-reported, objectively measured and physiological outcomes in people with multimorbidity (i.e. at least two of the following conditions: OA (knee or hip), heart condition (HF or CHD), hypertension, T2DM, COPD and depression). The primary endpoint is 12 months, but 4- and 6-month follow-ups are included as well and a 12-month health economic evaluation of the program will be conducted. Prior to the RCT, a feasibility trial of 20 people with multimorbidity, all undergoing the personalized exercise therapy and self-management support program, will be conducted using the same methods as in the RCT, but primarily focusing on feasibility outcomes (recruitment, retention, adherence to treatment, burden of outcomes, improvements in outcomes, adverse events). This will start recruitment in Feb 2021 and end August 2021. The MOBILIZE project has received funding from several foundations, including the European Research Council (ERC) under the European Union's Horizon 2020 research and innovation program (grant agreement No 801790).
The chronic coronary artery disease could be detected by a drop in the expression of A2A receptors to adenosine, while high values of the KD / EC50 ratio are a sign of coronary ischemia. Knowing the number of A2A receptors in circulating lymphocytes could allow detection of coronary artery disease and evaluating the functionality of A2A receptors in circulating lymphocytes could allow quantification of myocardial ischemia. Thus, a simple and unique blood sample would quickly detect patients with life-threatening coronary ischemia. This would avoid prolonged hospitalizations and costly non-invasive tests (stress echocardiography, myocardial scintigraphy) in patients without coronary artery disease.
In this study coronary artery disease patients and patients with heart failure will be randomly assigned to three training groups: combined aerobic interval training with high intensity resistance training, combined aerobic interval training with low intensity resistance training and aerobic interval training.
