Active clinical trials for "Heart Diseases"

Prospective registry for multifactorial risk factor assessment, enrolling consecutive ischemic stroke/transient ischemic attack patients with structural, inflammatory, or arrhythmogenic cardiac disease, who are admitted to our University Hospital.

Percutaneous coronary intervention is currently one of the effective methods for the treatment of ACS. Unfortunately, the incidence of ISR is as high as 10%-20% at 3-6 months after PCI. So it is necessary to identify the potential risk factors to provide evidence for the prevention of ISR. Current research shows that anxiety and depression are related to the increased risk of major adverse cardiac events and mortality in patients with acute myocardial infarction. But there remains a relative paucity of evidence for the association between anxiety and depression and in-stent restenosis (ISR) .So a retrospective cohort study was conducted in the first hospital of Qinhuangdao in 2015-2020. The patients who underwent coronary angiography 1 year after PCI in our hospital from January 2015 to September 2020 were selected. Patients were divided into ISR and non-ISR groups depending on the follow-up coronary angiography results. Logistic regression model was utilized for analyzing the association of depression and anxiety with the in-stent restenosis (ISR) after PCI.

The purpose of this study is to investigate the efficacy and mechanism of Adipokines Cardiac Protection in Obese Patients With coronary artery disease (CAD).

Prostaglandin E1 (PGE1) has been used in the medical treatment of ductal dependent critical congenital heart disease in neonates. Apnea/ bradycardia, hypotension, hypokalemia, feeding difficulties, fever, jitteriness are the most important side effects of PGE1. Also gastric outlet has been reported. We aimed to determine effect of PGE1 treatment on pyloric wall thickness in newborn period. In this study, the side effect of increase of pylorus muscle wall thickness will be monitored with weekly ultrasonography. No intervention in the treatment, medical decisions and follow-up of these patients will be made. After reaching the sufficient number of cases (20 cases), increases in the pyloric wall thickness dimensions will be compared with statistical analysis. The number of cases was determined in accordance with the rate of hospitalization in our unit during the determined period (18 months).

Despite the rapid development of medical and nursing technology, the prognosis of valvular heart disease has been greatly improved. However, compared with young patients, the mortality and adverse event rate of elderly patients with valvular heart disease are still high, surgical complications are more frequent and hospitalization time is longer. The complexity of valvular heart disease and the poor prognosis in the elderly forces us to continue to look for other potential prognostic factors. In addition to the adverse outcomes caused by disease factors, elderly patients with valvular heart disease also have the gradual decline of physiological and psychological reserve function caused by age factors. These adverse outcomes include osteopenia, disability, prolonged hospitalization and even death are all closely related to frailty. Frailty is 'a biologic syndrome of decreased reserve and resistance to stressors, resulting from cumulative declines across multiple physiologic systems, and causing vulnerability to adverse outcomes. The essence of frailty is the decline of individual resistance, which eventually leads to the increase of individual brittleness and susceptibility to adverse health outcomes. At present, the research in the field of elderly vulnerable groups of cardiovascular disease in China started late, mostly focusing on the study of pathological mechanism, the introduction of evaluation tools, conceptual analysis and so on. Almost all of the existing studies are about the debilitation status of elderly patients with heart valve disease, and most of them mainly try to find the influencing factors of debilitation from the aspects of patients' physical diseases, ignoring the impact of factors such as the mental health status of the elderly on debilitation, there are few reports of short-term adverse events in elderly patients with valvular heart disease. This study will analyze the influencing factors of the weakness of elderly patients with valvular diseases from the multi-dimensional aspects of demographic data, physical diseases, psychology and society, and track the short-term prognosis of patients with death, fall and unconventional rehospitalization, so as to provide a research basis for relevant research in the future.

Congenital heart disease (CHD) is the leading cause of birth defects, with an incidence of 0.8%. Among CHD, univentricular heart disease or "single ventricle" is rare and complex. As a result of the improved patient care over the last decades, the number of children and adults with single ventricle is increasing significantly. Today, the main challenge is to ensure an optimal follow-up of these new patients in order to improve their life expenctancy as well as their quality of life (QoL). Currently, echocardiography and cardiopulmonary exercice test (CPET) are central in management of patients with single ventricle as part of good clinical practice guidelines. Single ventricle volumes and function are very difficult to asses with conventional echocardiography because of their complex geometry. Indeed, single ventricle size and morphology vary depending on the patient characteristics and on the initial CHD (before surgical repair). That's why conventional 2D echocardiographic parameters are not reliable for single ventricle assessment. Magnetic resonance imaging (MRI) is more effective in assessing single ventricle volumes and function. Nevertheless, MRI is not universally available, is not practical in many situations, is expensive, and is a relative contraindication in patients with pacemakers. Over the past decade, the use of the 3D echocardiography has increased. This is an available tool that can assess ventricular function and volumes in few seconds. Recent studies shown a good correlation between 3D echocardiography and MRI for assessment of ventricular volumes and function in patient with CHD and especially in those with single ventricle. Moreover, according to some authors, CPET parameters are strongly correlated with risk of hospitalization, risk of death, physical activity and quality of life, especially in patients with single ventricle. To date, there is no study performed about the relationship between 3D echocardiography and CPET parameters in patients with single ventricle.

The purpose of this study is to develop imaging protocols when using cardiovascular magnetic resonance (CMR) to assess cardiac functions, morphology and tissue characterization. The National Heart Research Institute Singapore (NHRIS) houses two dedicated CMR scanners to support the numerous investigator initiated projects in patients with various cardiac pathologists. By optimizing novel CMR sequences used in these studies, scanning time can be shortened for patients with underlying cardiac diseases.

Current European Society of Cardiology Guidelines recommend concomitant atrial fibrillation (AF) ablation for all symptomatic patients undergoing other cardiac surgeries, but the safety and potential benefits of concomitant atrial fibrillation (AF) ablation at the time of double valve replacement remains unexamined. A retrospective review of patients with AF who underwent double valve replacement with or without concomitant surgical ablation in our institute starting from April 2006.

The purpose of this study is to evaluate the incidence of late incomplete stent apposition (ISA) and un-coverage by optical coherence tomography (OCT) following everolimus-eluting stent (EES) with bioabsorbable polymer (SYNERGY™, Boston Scientific,Nattick, MA, USA) versus zotarolimus-eluting stent (ZES) with permanent polymer(Resolute Onyx™, Medtronic, Santa Rosa, CA, USA) implantation in patients with AMI at 12 months.
