Active clinical trials for "Heart Diseases"

Fibrotic valvular heart diseases are known as rare complications of long-time therapy of Parkinson's disease with ergot-derivatives including some ergot-dopamine agonists. The aim of this study is to assess the incidence of valvular heart disease, which may be an ergot-drug agonists side-effect or an overall complication of all dopamine agonists. Incidence, prevalence and addiction of dose or intake duration are not known so far. The reversibility of the changes is unknown too. To answer these questions the present study is designed as a cross sectional study followed by a 2 year follow-up prospective cohort study.

This observational study will follow participants who completed follow-up in the FOURIER OUTCOMES trial to evaluate the long-term effects of evolocumab treatment. Long-term post-trial (legacy) beneficial effects have been reported with statins, niacin, hypoglycemic therapy and fibrates. Whether similar effects are seen after LDL cholesterol (LDL-c) lowering by PCSK9 inhibition is currently unknown. Evolocumab therapy causes a profound reduction in LDL cholesterol of approximately 60%. Statins have shown legacy effects over 5 years post-trial, including a 7% reduction in total mortality in meta-analysis and 12% reduction in coronary mortality. It would therefore be hypothesized that additional effects beyond the trial period would be conferred by previous evolocumab treatment. It is also important to assess the long-term safety of prior evolocumab treatment.

Patients are part of a family network. When any person in a family becomes critically unwell and requires the assistance of an Intensive Care Unit (ICU), this has an impact on all members of that family. COVID-19 changed visiting for all patients in hospitals across Scotland. It is not known what effect these restrictions will have on patients' recovery, nor do we understand the impact it may have on their relatives or staff caring for them. This study will look at the implications of the visiting restrictions as a consequence of the COVID-19 pandemic upon patients without COVID-19 who are in the cardiothoracic ICU. It will also explore the impact of these restrictions on them, their relatives and staff. This study will be carried out within a single specialised intensive care unit in Scotland using mixed methods. The first arm of this study will use retrospective data that is routinely collected in normal clinical practice. The investigators will compare patient outcomes prior to COVID-19 with outcomes following the implementation of COVID-19 visiting restrictions. The aim is to establish if the restrictions on visiting has an impact on the duration of delirium. Delirium is an acute mental confusion and is associated with longer hospital stays and worse outcomes in this patient group. The second arm of this study involves semi-structured interviews with patients, relatives and staff that will allow deeper exploration of the issues around current visiting policy. The interviews will last approximately 1 hour and will address these issues. They will then be transcribed word for word and analysed using grounded theory, meaning the theories will develop from the data as it is analysed.

The objective of this study is to determine the effectiveness of a real time continuous risk analytics algorithm in the successful de-escalation of vasoactive and inotropic support in pediatric patients following cardiac surgery.

Hypertension is a serious threat to human health and a major global economic burden. Chronic hypertension can cause left ventricular remodeling and loss of function, eventually leading to heart failure. Exploring the early changes and mechanisms of left ventricular cardiac function caused by hypertension, and to identify individuals who may develop into serious heart injury, may play a positive role in the early prevention and control of heart failure caused by hypertension. Therefore, this study intend to use two dimensional speckle tracking technology, a non-invasive method to measure left ventricular pressure-strain loop to quantitatively reflect cardiac work index , to study different hypertension patients with normal left ventricular ejection fraction the change of the global and local cardiac work, and the influence of aterosclerosis in the patients to myocardial work, and explore their relationship with ventricular remodeling and abnormal diastolic function. To improve the understanding of the pathophysiology of hypertension, hypertensive heart disease and heart failure, and to provide scientific support for the early prevention and control of such diseases. Myocardial work analysis Echocardiography plays a central role in the evaluation of patients with cardiovascular disease. Echocardiography is widely available and allows characterization of the functional and structural of heart. Thus, assessment of left lentricular (LV) global longitudinal strain (LVGLS) and Myocardial work indexes has proven benefit for both diagnosis and risk in hypertension patients.

A retrospective cohort study was performed in patients with angina pectoris who were treated with oral Chinese patent medicine and Western medicine.The hospital's medical record management system was used to collect symptoms of angina pectoris, dose and frequency of nitroglycerin use, clinical biochemical test and imaging examination.To explore the clinical efficacy of Chinese patent medicine in the treatment of coronary heart disease with angina pectoris, and provide reliable data support for its clinical application.

Patients undergoing treatment for heart disease through percutaneous interventions admitted to intensive care units often suffer from sleep deprivation, with multifactorial factors being the precursors of this problem. Sleep deprivation has a negative impact on rehabilitation, with increased morbidity and mortality. Therefore, implementing non-pharmacological measures for this population is essential for better quality care, as well as more satisfactory experiences. The Objectives are to evaluate whether the non-pharmacological intervention that includes the use of eye masks and hearing protectors has an influence on the quality of sleep of patients undergoing percutaneous interventions for the treatment of heart diseases admitted to the intensive care unit, to compare the quality of sleep between patients according to sociodemographic and clinical variables and to identify whether anxiety is a factor associated with sleep quality in patients undergoing percutaneous interventions for the treatment of heart disease in patients admitted to the intensive care unit. Randomized clinical trial blinded to the steps of data collection and data analysis, with two groups of participants in which the intervention with eye masks and ear protectors will be evaluated. The inclusion criteria in the study will be patients undergoing percutaneous intervention treatment for heart disease over the age of 18, preserved communication skills and understanding. The study site will be a cardiac intensive care unit in a private hospital of high complexity in the city of São Paulo. The intervention will be carried out during the period of hospitalization in the intensive care unit, by nurses trained by the researcher from 9 pm until the patient awakens, and variables related to sleep quality, anxiety, pain, delirium and length of stay will be collected. in bed. The sample will consist of 80 patients divided into two groups (intervention and control) and the data will be analyzed with descriptive statistics, with Student t test and Mann Whitney test for comparison between groups and with Chi-square test and Spearman for analysis of categorical variables. . Relative risk, odds ratio will be calculated and the level of significance adopted will be 5%. It is intended to know if the non-pharmacological intervention brings benefits to reduce sleep deprivation and contributes to better clinical outcomes.

Non-invasive reconstruction of electrical heart activity can yield important scientific and clinical insights in cardiac rhythm disorders. In this study, The investigators aim at developing methods for reconstructing electrical heart activity non-invasively, and to use these methods to investigate cardiac rhythm disorders to answer clinical and scientific questions.

Assessment of the clinical safety and performance of the Orsiro drug-eluting stent in a real world setting in patients with small vessels with reference vessel diameter ≤2.75 mm

The European Association for the Study of Diabetes (EASD) guidelines have not made any specific recommendations regarding the Dietary Approaches to Stop Hypertension (DASH) diet, a dietary pattern that emphasizes fruits and vegetables, low-fat or non-fat dairy, limiting saturated fat intake and usually also recommends limiting sodium intake. To update the recommendations, the Diabetes and Nutrition Study Group (DNSG) of the EASD commissioned an umbrella review of systematic reviews and meta-analyses using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach to summarize the available evidence from recent systematic reviews and meta-analyses of prospective cohort studies and randomized and non-randomized controlled trials of the relationship between the DASH dietary pattern and cardiometabolic risk.
